    A prospective study identified 45 patients with malignancy-related ascites among 448 ascites patients (10% of the total). Patients were categorized into five subgroups based on the pathophysiology of ascites formation. Each subgroup had a distinctive ascitic fluid analysis. Patients with peritoneal carcinomatosis but without massive liver metastases (53.3% of the patients with malignancy-related ascites) had a uniformly positive ascitic fluid cytology, high ascitic fluid protein concentration and low serum-ascites albumin gradient. Patients with massive liver metastases and no other cause for ascites formation (13.3% of the series) had a negative cytology, low ascitic fluid protein concentration, high serum-ascites albumin gradient and markedly elevated serum alkaline phosphatase. Those with peritoneal carcinomatosis and massive liver metastases (13.3% of the series) had a nearly uniformly positive ascitic fluid cytology, variable protein concentration, high serum-ascites albumin gradient and markedly elevated serum alkaline phosphatase. Chylous ascites (6.7%) was characterized by a milky appearance, negative cytology and an elevated ascitic fluid triglyceride concentration. Patients with hepatocellular carcinoma superimposed on cirrhosis (13.3%) had negative ascitic fluid cytology, low ascitic fluid protein concentration, high serum-ascites albumin gradient and elevated serum and ascitic fluid alpha-fetoprotein concentration. Two-thirds of patients with malignancy-related ascites had peritoneal carcinomatosis; 96.7% of patients with peritoneal carcinomatosis had positive ascitic fluid cytology. Ascitic fluid analysis is helpful in identifying and distinguishing the subgroups of malignancy-related ascites.

    Ascites is a common complication of hepatic cirrhosis and portal hypertension. Patients present systemic and splanchnic circulation disorders, which cause central hypovolemia and arterial hypotension, with the subsequent activation of vasoconstrictor systems and increased renal reabsorption of sodium and water. Approximately 5%-10% of patients present refractory ascites. Refractory ascites is considered when it is not controllable with standard dietary (sodium restriction) and diuretic (furosemide up to 160 mg a day and spironolactone up to 400mg a day) treatment or when patients present adverse effects due to diuretics that impede their administration at optimum dosages. The current therapeutic options for these patients are repeated evacuative paracentesis and the percutaneous intrahepatic portosystemic shunt. Despite these treatments, refractory ascites has a poor prognosis; patients should therefore be assessed for liver transplantation.

  3. [Laboratory chemical analysis in ascites].

    Chemical analysis of ascitic fluid may be helpful in determining the underlying disease. We discuss the diagnostic accuracy of the common and newer chemical parameters (protein, LDH, lactate, glucose, cholesterol, triglycerides, phospholipids, fibronectin, albumin gradient [value of serum minus value of ascites], ferritin, tumor markers, immunomodulators, leukocytes, bacterial and cytologic examinations). We also review the pathogenesis and clinical findings of the most frequent ascites forms (benign hepatic, infective, malignant ascites, ascites associated with liver metastases or hepatocellular carcinoma, cardiac and pancreatic ascites) and the most important diagnosis criteria. In the malignant ascites a high cholesterol, a narrow albumin gradient or a high ferritin value have high diagnostic accuracy, but diagnosis is by the finding of malignant cells. For the diagnosis of infective ascites, bacteriology is mandatory even though the results are negative in most cases, particularly in spontaneous bacterial peritonitis where diagnosis has to be established clinically, by a low pH or by a high leukocyte count. Benign hepatic ascites is diagnosed by demonstrating an underlying chronic liver disease and laboratory examinations of the peritoneal fluid to exclude other causes. The laboratory tests in ascites associated with liver metastases or with hepatocellular carcinoma were similar to those in benign hepatic ascites and the two ascites forms must be separated by other clinical and technical findings. Pancreatic ascites can easily be distinguished from the other forms by the high amylase and lipase content.

  4. Diagnosis of malignant ascites. Comparison of ascitic fibronectin, cholesterol, and serum-ascites albumin difference.

    1988-07-01

    The ascitic fluid concentrations of cholesterol and fibronectin and the serum-ascites albumin difference were compared with two conventional tests of ascitic fluid, total protein and LDH, in their diagnostic ability for detection of malignancy in ascitic samples from 69 patients with ascites: 54 with ascites due to liver disease and 15 whose ascites was caused by peritoneal metastases. Sixteen cirrhotic patients with superimposed hepatocellular carcinoma in whom ascites was of uncertain etiology were considered separately. The mean ascitic fluid total protein, LDH, cholesterol, and fibronectin values in the peritoneal metastases group were 3.70 +/- 1.20 g/dl, 247.26 +/- 148.14 units/liter, 109.06 +/- 29.85 mg/dl, and 91.57 +/- 41.52 micrograms/ml, respectively, and all were significantly higher than the corresponding values in the liver disease group (P less than 0.001), which were 1.37 +/- 0.59 g/dl, 75.40 +/- 110.70 units/liter, 23.75 +/- 11.22 mg/dl, and 31.86 +/- 10.51 micrograms/ml, respectively. Mean serum-ascites albumin difference in the peritoneal metastases group was 0.62 +/- 0.38 g/dl, which was significantly different from the corresponding value in the liver disease group (1.92 +/- 0.41 g/dl, P less than 0.001). Both ascitic cholesterol above 46 mg/dl and an ascitic fibronectin concentration greater than 50 micrograms/ml had high diagnostic accuracy (97%) for malignancy, being higher than that achieved using a serum-ascites albumin difference under 1.1 g/dl and an ascitic total protein above 2.5 g/dl, which had accuracies of 94% and 93%, respectively. Ascitic fluid LDH was the least reliable test. No differences in the ascitic fluid analysis were found between cirrhotic patients with and without hepatocellular carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

  5. Usefulness of serum-ascites albumin difference in separating transudative from exudative ascites. Another look.

    PubMed

    Mauer, K; Manzione, N C

    1988-10-01

    The serum-ascites albumin difference is reported to be superior to ascitic total protein, ascitic-to-serum total protein ratio, lactic dehydrogenase, and ascitic-to-serum lactic dehydrogenase ratio in differentiating between ascites from liver disease and malignant ascites, S-A greater than 1.1 reflecting portal hypertension. We analyzed ascitic fluid from 46 consecutive patients with chronic liver disease, 28 patients with ascites associated with malignancy, 10 patients with right-sided heart failure, 4 patients with hypothyroidism, and 6 patients with miscellaneous causes of ascites to determine if this albumin difference is indeed a more valuable parameter. Analysis of our data confirms with a larger number of patients that the serum-ascites albumin difference is a more reliable indicator of transudative ascites, better termed portal hypertensive ascites. Malignant ascites without liver metastases had features of nonportal hypertensive ascites, and the serum-ascites albumin difference confirms this. The characteristics of malignant ascites associated with liver metastases, however, resemble those of the portal hypertensive ascites complicating liver disease. This new parameter is also helpful in distinguishing congestive heart failure with high protein ascites and portal hypertensive ascitic features from malignant ascites without liver metastases. Of particular note, myxedematous ascitic fluid, classically categorized as exudative, had an S-A greater than 1.1, indicating the possible role of portal hypertension in the development of ascites in these patients.

    Ascites has been a common pathological sign among prehispanic Mexican people, as a result from hepatic and cardiac ailments. In this sense it represents a significant epidemiological problem. But it also is important because is related to Tlaloc and the rain gods and goddesses. The hidropic body is a symbolic water container and have a special function: serve as a Tlaloc and related gods vehicle to transport the precious liquid. In this paper we analyze the Tlaloc role as water and alimentary substances provider and his capital importance for people survival. We also describe five different plastic ways to represent water in the body, all of them with clear relationships to Tlaloc.

  7. Massive ascites of unknown origin

    Massive ascites of unknown origin is an uncommon condition, which represent a diagnostic challenge. Patients with delayed diagnosis and treatment may have a poor prognosis. A 22-year-old female was referred to this hospital due to a 4-year progressive abdominal distension with massive ascites of unknown origin. By thorough investigations, she was eventually diagnosed as chronic calcified constrictive pericarditis. She received pericardiectomy and had an uneventful postoperative course. With a few day paracentesis, ascites did not progress any more. She was doing well at 5-month follow-up and has returned to work. Extracardiac manifestations, such as massive ascites and liver cirrhosis, were rare in patients with constrictive pericarditis. Pericardiectomy can be a radical solution for the treatment of chronic constrictive pericarditis. In order to avoid delayed diagnosis and treatment, physicians have to bear in mind this rare manifestation of chronic calcified constrictive pericarditis. PMID:24600502

    Cirrhosis is the final stage of most of the chronic liver diseases and is most invariably complicated by portal hypertension resulting in ascites. A case of chronic liver disease with portal hypertension (cryptogenic cirrhosis), managed at Amrita School of Ayurveda is discussed in this paper. The clinical picture was that of an uncomplicated cirrhotic ascites. Snehapāna (therapeutic oral administration of lipids) followed by virecana (purgation) was done after an initial course of nityavirecana (daily purgation). Later Vardhamāna pippalī rasāyana [administration of single drug - pippalī (piper longum) in a structured dose pattern] was administered with an intention of rejuvenating liver cells. Ascites and lower limb oedema were completely resolved after the therapy. No recurrence of ascites has been reported after a follow up period of one year. PMID:27621523

    Serial ascites and plasma volumes were measured during diuresis in nine patients with ascites caused by peritoneal carcinomatosis, four patients with chylous malignant ascites, and three patients with portal hypertension-related ascites caused by massive hepatic metastases. Oral diuretics were given to achieve an adequate natriuresis on a sodium-restricted diet. During the study period (7.8 +/- 3.2 days), patients with peritoneal carcinomatosis and chylous ascites lost 0.49 +/- 0.31 and 0.51 +/- 0.42 kg/day in weight, respectively, with negligible change in ascites volumes (-0.03 +/- 0.11 and 0.02 +/- 0.09 L/day). Patients with ascites caused by massive hepatic metastasis lost 1.06 +/- 0.15 kg/day in weight (P = 0.01 for massive hepatic metastasis vs. peritoneal carcinomatosis) and 0.23 +/- 0.13 L/day of ascites (P less than 0.05 vs. other groups). Plasma volume changes were not significantly different among the three groups. Patients with edema (9/16) had a greater natriuresis and daily weight loss. Three patients with peritoneal carcinomatosis and one with chylous ascites developed renal dysfunction or symptomatic hypotension. No patient with massive hepatic metastasis developed these complications. In patients with ascites caused by peritoneal carcinomatosis or chylous malignant ascites there is no mobilization of ascites, whereas in patients with massive hepatic metastasis, ascites may be mobilized with diuretics.

    2013-01-01

    Ascites is a pathologic accumulation of peritoneal fluidcommonly observed in decompensated cirrhotic states.Its causes are multi-factorial, but principally involve significant volume and hormonal dysregulation in the setting of portal hypertension. The diagnosis of ascites is considered in cirrhotic patients given a constellation of clinical and laboratory findings, and ultimately confirmed, with insight into etiology, by imaging and paracentesis procedures. Treatment for ascites is multi-modal including dietary sodium restriction, pharmacologic therapies, diagnostic and therapeutic paracentesis, and in certain cases transjugular intra-hepatic portosystemic shunt. Ascites is associated with numerous complications including spontaneous bacterial peritonitis, hepato-hydrothorax and hepatorenal syndrome. Given the complex nature of ascites and associatedcomplications, it is not surprising that it heralds increased morbidity and mortality in cirrhotic patients and increased cost-utilization upon the health-care system. This review will detail the pathophysiology of cirrhotic ascites, common complications derived from it, and pertinent treatment modalities. PMID:23717736

    Less than four percent of patients with hypothyroidism develop ascites. Ascites as the presenting feature of hypothyroidism is uncommon, hence diagnosis is often delayed. Once it is diagnosed, treatment of hypothyroidism leads to quick clinical improvement in ascites. We report a case of a female patient who presented with ascites secondary to severe hypothyroidism and discuss the diagnostic characteristics of the ascitic fluid in myxedema ascites on the basis of literature review.

    1. B- and M-mode echocardiography was used to compare cardiac function in broilers with spontaneous ascites syndrome with that of normal chickens. 2. Thirty ascitic chickens and 15 normal chickens aged three, 4, 5, and 6 weeks from the same flock (180 birds in total) were examined. They were restrained gently in a natural standing position, and echocardiographs were obtained from a 7.0-MHz linear transducer placed on the left pectoral apterium. Indices of cardiac structure and functioning were calculated from the echocardiographs, and some were normalised to body weight. Heart rate was also measured. 3. All cardiac structural indices in both ascitic and normal chickens increased with age. Compared with normal chickens, right ventricular diameter at the end of systole in ascitic chickens was greater at 4, 5 and 6 weeks of age. Ventricular septal thickness at the end of both systole and diastole was greater in ascitic chickens at 5 and 6 weeks. Left ventricular free wall thickness at the end of diastole was less in ascitic chickens at 3 weeks. However, all the structural indices decreased with age after normalisation with body weight. 4. The heart rate of ascitic chickens was lower at 4, 5 and 6 weeks. Normalised left ventricular fractional shortening was lower in ascitic chickens at 4, 5 and 6 weeks, as was normalised right ventricular fractional shortening. Incrassation of the ventricular septum (Delta T), which changed little in normal chickens, was less at 4, 5 and 6 weeks in ascitic chickens. Left ventricular fractional shortening, right ventricular fractional shortening and Delta T were all negatively correlated with ascites heart index at all ages. 5. Taken together the results suggest heart failure of both ventricle, but that right ventricular dysfunction is more extensive than left ventricular dysfunction. We suggest that secondary pulmonary hypertension would result in these ascitic chickens due to volume overload.

    The ascitic fluid ferritin concentrations were compared with serum-ascites albumin gradient (SAAG), in their diagnostic ability for detection of malignancy in 60 patients with ascites: 29 with chronic liver disease alone (CLD) and 31 patients with various neoplasms. Of the patients with malignancy, 12 had liver metastases, 9 had no evidence of liver involvement, and 10 had hepatocellular carcinoma (HCC) with or without coexisting liver cirrhosis. Analysis of our data confirms that the ascitic ferritin is a more accurate indicator of malignant ascites (MA) than the SAAG. This new parameter is particularly helpful in distinguishing MA associated with HCC and/or metastatic liver disease from nonmalignant ascites due to CLD alone.

    Massive hemorrhagic ascites (4470 mL, range 1-10 L) in women with endometriosis is a rare condition occurring predominantly in black women. Of the 43 case reports published, 42 are compatible with the hypothesis that the hemorrhagic ascites is predominantly a consequence of excessive ovarian transudation similar to a Meigs syndrome. Indeed, bilateral ovariectomy cures the condition without recurrences, whereas after unilateral ovariectomy or cystectomy recurrence rate is more than 50%; during ovarian suppression by luteinizing hormone-releasing hormone agonist ascites disappears, but reappears after treatment. Superficial pelvic endometriosis also contributes to the ascites because after superficial endometriosis destruction the recurrence rate is only 4 in 14. Based on these data, it is suggested, to scrutinize the ovaries for tumors given the analogy with Meigs syndrome. In women desiring fertility, conservative treatment with destruction of endometriosis only can be attempted given the cure rate of some 20%. It is unknown what the effect of ovulation induction would be.

    The aim of this study was to test the diagnostic value of ascitic fluid cholesterol and triglycerides concentrations and of serum-ascites albumin concentration gradient in the differentiation between cirrhotic and malignant ascites. These biological parameters were determined, on the one hand in 34 cirrhotic patients, 6 of them having an hepatocellular carcinoma and 6 others having a spontaneous bacterial peritonitis and, on the other hand, in 16 patients with malignant ascites, 13 of them having an abdominal extra-hepatic or pelvic cancer, and 3 others having an extra-abdominal cancer with multiple liver metastases. Ascitic carcinoembryonic antigen assay and ascitic fluid cytology were also done in the 50 patients. In differentiating the cirrhotic patients from those with malignancy, ascitic fluid cholesterol concentration (discriminating value less than 1.1 mmol/l) ascitic fluid triglycerides concentration (discriminating value 0.5 mmol/l) and serum-ascites albumin concentration gradient (discriminating value greater than 11 g/l) allowed a diagnostic efficiency of 0.92, 0.80 and 0.77, respectively. Ascitic fluid cytology showed presence of malignant cells in 3/6 patients with hepatocellular carcinoma associated with cirrhosis, in 9/16 patients having a malignant ascites, and was negative in other patients. Ascitic carcinoembryonic antigen assay was abnormal only in 3/16 patients with malignant ascites. These results suggest that measurement of ascitic fluid cholesterol concentration must be included in the initial evaluation of patients with ascites of unknown origin.

    An African pygmy hedgehog (Atelerix albiventris) was diagnosed as chylous ascites with biliary cirrhosis. Abdomenocentesis revealed a milky fluid with a 324 mg/dl triglyceride level. On serum biochemical examination, the hedgehog had hypoalbuminemia, hypoglycemia, and high blood urea nitrogen. There was no cytologic or genomic evidence of infection, and a blood culture was negative. Histopathologic examination revealed a liver with proliferative bile ducts that were often surrounded by prominent septa of fibrous connective tissue. In the area of ductular reaction, proliferative cells positive for CD66, an embryogenic antigen of epithelial cells, were revealed. The potential association between chylous ascites and liver cirrhosis is undetermined but could be an aspect of future study. This is the first description of chylous ascites in a hedgehog.

    2016-01-01

    Eosinophilic gastroenteritis (EGE) is a rare condition characterized by eosinophilic infiltration of the gastrointestinal tract. Depending on the dominant layer of infiltration it is classified into three types namely, mucosal, muscularis and subserosal. The most uncommon variant is the subserosal type characterized by primarily subserosal disease, eosinophilic ascites and peripheral hypereosinophilia. The clinical features are non-specific with history of atopic predisposition and allergy. Endoscopic biopsy is frequently non-diagnostic due to an uninvolved gastrointestinal mucosa rendering its diagnosis a challenge. The mainstay of diagnosis is peripheral hypereosinophilia and eosinophil-rich ascitic fluid on diagnostic paracentesis. Oral steroid therapy is usually the first line of treatment with dramatic response. Due to a propensity for relapse, steroid-sparing therapy should be considered for relapses of EGE. We report a case of subserosal EGE with diagnostic clinical features and treatment response and review the current strategy in the management of eosinophilic ascites. PMID:27721930

    2016-01-01

    Background. Pelvic inflammatory disease (PID) rarely results in diffuse ascites. Severe adhesive disease secondary to PID may lead to the formation of inclusion cysts and even pelvic peritoneal nodularity due to postinflammatory scarring and cause an elevation of serum CA-125 levels. The constellation of these findings may mimic an ovarian neoplasm. Case. We report a case of a 22-year-old female who presented with multiple pelvic cysts and diffuse ascites due to Chlamydia trachomatis infection. The initial gynecologic exam did not reveal obvious evidence of PID; however, a positive Chlamydia trachomatis test, pathologic findings, and the exclusion of other etiologies facilitated the diagnosis. Conclusion. Chlamydia trachomatis and other infectious agents should be considered in the differential diagnosis of a young sexually active female with abdominal pain, ascites, and pelvic cystic masses. Thorough workup in such a population may reduce the number of more invasive procedures as well as unnecessary repeat surgical procedures. PMID:27747116

    In a prospective study of 98 consecutive patients with undiagnosed ascites examined by laparoscopy a correct immediate diagnosis was made in 76 (78%) and a final diagnosis in 92 (94%) of those who underwent laparoscopy. Visual diagnosis was highly accurate in patients with tuberculous peritonitis but only moderately accurate in those with carcinomatosis and liver disease. When the laparoscopic findings were compared with histological and microbiological results visual diagnosis was found to be the most accurate diagnostic method. Laparoscopy may readily be used in rural hospitals for diagnosing ascites. PMID:3160432

    Cirrhotic patients with refractory ascites (RA) can be treated with repeated large volume paracentesis (LVP), with the insertion of a transjugular intrahepatic portosystemic shunt (TIPS) or with liver transplantation. However, side effects and complications of these therapeutic options, as well as organ shortage, warrant the development of novel treatments. The automated low-flow ascites pump (alfapump(®)) is a subcutaneously-implanted novel battery-driven device that pumps ascitic fluid from the peritoneal cavity into the urinary bladder. Ascites can therefore be aspirated in a time- and volume-controlled mode and evacuated by urination. Here we review the currently available data about patient selection, efficacy and safety of the alfapump and provide recommendations for the management of patients treated with this new method.

    Chylous ascites is a rare complication of abdominal surgery in children. Particularly, reports of postoperative chylous ascites are rare. This report describes the very rare case of a 10-month-old girl complicated by chylous ascites after resection of a choledochal cyst with a Roux-en-Y hepaticojejunostomy, who was successfully treated medically. To date, we have found a few cases of postoperative chylous ascites in the paediatric literature. To the best of our knowledge, this is the first report of chylous ascites after the resection of a choledochal cyst in a child who was successfully treated solely by no fasting. No fasting might be a therapeutic option of paediatric postoperative chylous ascites after the resection of a choledochal cyst if the outflow volume of chylous ascites is small.

    An ascites syndrome was induced in 17 to 28 per cent of specific pathogen-free (SPF) Light Sussex (LSX) chickens given a low protein (16 per cent crude protein) high calcium (3.5 per cent calcium) layer crumble feed on two separate occasions 6 months apart. Affected chickens had increased right ventricular weight as a proportion of either total heart weight or live-weight at 3 weeks of age, compared with non-affected LSX chickens on the same feed, thus indicating right ventricular hypertrophy. The incidence of ascites was not increased by infection with avian nephritis virus, nor by limited cold-stress during brooding. It was not produced in LSX chickens given other feeds, nor in SPF Rhode Island Red chickens.

    1990-01-01

    The authors have analyzed sixty cases of ascites including twenty of neoplastic origin and thirty-six of cirrhotic origin in order to evaluate the usefulness of several laboratory tests for the differential diagnosis of ascites. The tests which gave more than 85% diagnostic accuracy were ascitic fluid concentrations of fibronectin and total protein, serum-ascites gradients of albumin and total protein concentrations, ascitic fluid concentrations of albumin and cholesterol. The last three tests gave a diagnostic accuracy of more than 92% at discriminant levels of 3.8 gr/dl, 1.6 gr/dl and 60 mg/dl, respectively. For these six tests, neoplastic ascites due to liver metastasis had values intermediate between cirrhotic ascites and neoplastic ascites due to peritoneal carcinomatosis. A serum-ascites albumin gradient of more than 1.1 gr/dl was indicative of portal hypertension in cirrhotic patients; the total protein serum-ascites gradient had a better diagnostic accuracy. Flow cytometry had less diagnostic accuracy than cytology; moreover, all cases with abnormal flow cytometry were already recognized by cytology.

    Preeclampsia is defined as new onset hypertension and proteinuria after 20 weeks of gestation and complicates approximately 2-8% of all pregnancies. Release of vasoconstrictive agents, endothelial damage, hyperpermeability of the capillaries and microangiopathic haemolysis involves the basic pathophysiology. It has variable clinical presentation. Here, we report a case of severe preeclampsia who developed postpartum massive ascites and pleural effusion. Primigravid patient was admitted to our clinic at 35 weeks of gestation with very high blood pressure. In biochemical analysis, Alanine aminotransferase (ALT) was 401 U/L, Aspartate aminotransferase (AST) was 292 U/L. An emergency caesarean section was performed because of fetal distress. On the 2nd post-operative day, abdominal distension and severe abdominal pain occurred. On the 3rd post-operative day, her abdominal distension increased and Ultrasonography (USG) revealed massive ascites. Abdominal drainage was performed and albumin infusion was administered. On postoperative day 4, she still had abdominal distension and concomitant respiratory distress. Computed Tomography (CT) showed ascites and bilateral pleural effusion. Her complaint regressed on the following days.

    The case of a 42-year-old woman with no previous disease admitted for abdominal pain and ascites is presented. Analysis of the ascitic fluid demonstrated high concentrations of amylase with normal lipase. The diagnosis of peritoneal mesothelioma was obtained by laparotomy. This association has not been previously described. The authors suggest that this diagnostic possibility should be considered in patients without pancreatic disease and high amylase levels in ascitic fluid.

    AIM: To study the patients with low gradient ascites in hospitals of Guilan Province (northern Iran). METHODS: Patients admitted in hospitals of Guilan Province with low gradient ascites from 1993 to 2000 were enrolled in the study. Serum and ascitic fluid albumin levels were determined by biochemical reactions. The serum-ascitic albumin gradient (SAAG) less than 1.1 g/dL was considered low. Statistical analysis was performed with SPSS 9.0 software and P<0.05 was considered statistically significant. RESULTS: Of the 148 patients enrolled in the study, 72 (48.6%) were males and 76 (51.4%) were females with a mean age of 59.03±13.54 years. Tuberculous peritonitis was the most frequent cause of low gradient ascites in 68 (45.9%). Other most frequent causes were cancer in 62 (41.9%), nephrotic syndrome in 9 (6%), pancreatitis in 6 (4%). Peritoneal cancer was found in 22 (35%), ovarian and gastric cancers were found in 14 (22.5%) and 12 (19.3%), respectively. All of which were the causes of ascites. The mean SAAG was 0.68±0.19 g/dL. The mean serum and ascitic fluid albumin concentrations were higher in tuberculous patients (P<0.006), but lactate dehydrogenase (LDH) level was higher in cancer patients (P<0.0001). In peritoneal tuberculosis, mean ascitic glucose concentration was significantly lower than other patients (P<0.0001). CONCLUSION: Tuberculosis should be considered in all patients with low gradient ascites especially in developing countries (like Iran), as the first cause of ascites. In the approach to patients with low gradient ascites, ascitic fluid glucose, and LDH level are useful indicators for decision making. PMID:15818749

    Spontaneous fungal peritonitis (SFP) is an infrequent but severe complication most commonly described in patients with liver cirrhosis. We present the first case of culture-proven SFP occurring in cardiogenic ascites. The diagnosis of SFP was clinically challenging as the initial ascites was consistent with the more common diagnosis of spontaneous bacterial peritonitis (SBP). The patient did not respond to antibacterial therapy, however, and the final diagnosis was only made with positive ascitic cultures that grew Candida glabrata. SFP should be considered in patients with either cardiac or cirrhotic ascites and have a delayed or lack of response to traditional SBP treatment. PMID:28386572

    Broiler chickens are intensively selected for productive traits. The management of these highly productive animals must be optimal to allow their full genetic potential to be expressed. If this is not done, inefficient production and several metabolic diseases such as ascites become apparent. The causes of the ascites are multifactorial but diet and, particularly, interactions between diet, other environmental and genetic factors play an important role. The relatively high heritability estimates for ascites-related traits and the significance of maternal genetic effects for most of the traits indicate that direct and maternal genetic effects play an important role in development of the ascites syndrome. An imbalance between oxygen supply and the oxygen required to sustain rapid growth rates and high food efficiencies causes ascites in broiler chickens. Because of the relationship to oxygen demand, ascites is affected and/or precipitated by factors such as growth rate, altitude (hypoxia) and environmental temperature. As the high metabolic rate (fast growth) is a major factor contributing to the susceptibility of broilers to ascites, early-age feed or nutrient restriction (qualitative or quantitative) or light restriction in order to slow down the growth rate seem practically viable methods, since final body weight is not compromised. Manipulation of the diet composition and/or feed allocation system can have a major effect on the incidence of ascites. Optimization of the house temperature and ventilation in cold weather seem helpful practices to decrease ascites incidence.

    This was a cohort analysis evaluating patients with pancreatic adenocarcinoma who presented with or developed ascites. Among the 180 patients analyzed, the use of serial paracenteses and indwelling catheters is a common practice to effect symptom palliation. The complication rate was higher in patients with indwelling catheters. Analyzing ascitic fluid and calculating the serum ascites albumin gradient can help attribute the etiology of the ascites and potentially identify which patients may benefit from diuretics or other intervention. Background Ascites develops in a subset of patients with pancreatic adenocarcinoma (PAC) at presentation or as the disease advances. Limited data exist on the prognostic importance of malignant ascites in PAC. Our hypothesis is that this information will provide an understanding of the natural history and facilitate management decisions. Methods We conducted a retrospective analysis of 180 patients treated at Memorial Sloan Kettering Cancer Center diagnosed between January 1, 2009 and December 31, 2014, with PAC and with ascites either at presentation or that developed during the disease course. Results For the 180 patients, the overall survival was 15 months. The time from diagnosis to ascites presentation was 11 months, and the survival time after ascites development was 1.8 months (range, 1.6–2.3 months; 95% confidence interval). Of 62 patients (34%) who had ascitic fluid analyzed, 36 (58%) had positive cytology. Fifty-one (82%) patients had a serum ascites albumin gradient ≥ 1, and 11 (18%) had serum ascites albumin gradient < 1. Sixty-four (36%) patients had their ascites managed solely by serial paracenteses. A total of 116 patients required a catheter; of these, 108 (93%) had a Tenckhoff catheter, 4 (3%) a Pleurx catheter, 4 (3%) a pigtail catheter, and 1 (1%) a Denver catheter. Eight (7%) patients required 2 catheters to be placed, and in 6 (5%), Tenckhoff catheters had to be removed. The main observed complications were

    Ascites, in 20% of cases, is not linked to liver cirrhosis. The pathophysiology is most often different. The understanding of these pathophysiological mechanisms can lead to etiologic diagnosis. The diagnostic approach is mainly based on the biological study of ascites, especially protein concentration and albumin gradient between serum and ascites. In Western countries, tumors and heart diseases are the predominant causes, while developing countries are mainly concerned by infectious diseases, among which tuberculosis is the leading cause. Other uncommon causes must be recognized, as ascites may be the presenting feature of the disease. Their knowledge will facilitate the therapeutic approach.

    The serum-ascites albumin (SAA) gradient has been defined as the serum albumin concentration minus the ascitic fluid albumin concentration. The SAA gradient is superior to the exudate-transudate concept to classify ascites, being a exact portal hypertension (PH) marker. An elevated SAA gradient (1.1 g/L or greater) correlates with PH, whereas a low gradient indicates no PH. The SAA gradient correlates well with PH in cirrhotic patients. It is also of particular utility to differentiate between congestive heart failure and malignant ascites without liver metastases (both of them with elevated ascites fluid proteins -AFP-). However, a low SAA gradient do not differentiate between tuberculous and malignant ascites. Consequently, there are still need for tests a cytology, culture for mycobacteria or ascites fluid polymorphonuclear cell count in some cases. The level of AFP, apart from the exudate-transudate concept, has some value for certain cases (a low level of AFP implicates a high risk of spontaneous bacterial peritonitis). The SAA gradient should replace the AFP concentration as the initial test to classify ascites.

    Malignant ascites affects approximately 10% of patients with gastric cancer (GC), and poses significant difficulties for both patients and clinicians. In addition to the dismal general condition of affected patients and the diversity of associated complications such as jaundice and ileus, problems in assessing scattered tumors have hampered the expansion of clinical trials for this condition. However, the accumulation of reported studies is starting to indicate that the weak response to treatment in GC patients with malignant ascites is more relevant to their poor prognosis rather than to the ascites volume at diagnosis. Therefore, precise assessment of initial state of ascites, repetitive evaluation of treatment efficacy, selection of suitable treatment, and swift transition to other treatment options as needed are paramount to maximizing patient benefit. Accurately determining ascites volume is the crucial first step in clinically treating a patient with malignant ascites. Ultrasonography is commonly used to identify the existence of ascites, and several methods have been proposed to estimate ascites volume. Reportedly, the sum of the depth of ascites at five points (named “five-point method”) on three panels of computed tomography images is well correlated to the actual ascites volume and/or abdominal girth. This method is already suited to repetitive assessment due to its convenience compared to the conventional volume rendering method. Meanwhile, a new concept, “Clinical Benefit Response in GC (CBR-GC)”, was recently introduced to measure the efficacy of chemotherapy for malignant ascites of GC. CBR-GC is a simple and reliable patient-oriented evaluation system based on changes in performance status and ascites, and is expected to become an important clinical endpoint in future clinical trials. The principal of treatment for GC patients with ascites is palliation and prevention of ascites-related symptoms. The treatment options are various, including a

    Ascites is the most common complication of cirrhosis and is associated with 50% mortality at 2 years if patients do not receive orthotopic liver transplantation. Recently the International Ascites Club defined ascites into three groups: In grade I ascites fluid is detected only by ultrasound; in grade II, ascites is moderate with symmetrical distention of the abdomen; and in Grade 3 ascites is large or tense with marked abdominal distention. About 10% of patients with ascites are refractory to treatment with diuretics. In refractory ascites, patients do not respond to highest doses of diuretics (spironolactone 400 mg/day and furosemide 160 mg/ day) or develop side effects (hyperkalemia, hyponatremia, hepatic encephalopathy, or renal failure) that prohibit their use. Patients may be treated either by repeated large volume paracentesis plus albumin or transjugular intrahepatic portosystemic shunts (TIPS). Dilutional hyponatremia in cirrhotic patients is defined as serum sodium < or = 130 mEq/L in the presence of an expanded extracellular fluid volume, as indicated by the presence of ascites and/or edema. This complication of cirrhotic patients with ascites has recently gained attention given that several reports indicate that when serum sodium concentration is combined with the Model for End-Stage liver disease (MELD) it improves the prognostic accuracy of MELD score in patients awaiting orthotopic liver transplant (OLT). The first step in the management of dilutional hyponatremia is fluid restriction and discontinuation of diuretics. Water restriction at 1,000 mL/day helps prevent the progressive decrease in serum sodium concentration but usually does not correct hyponatremia in most cases. Actually are developing drugs that are active orally and act by selectively antagonizing the specific receptors (V2 receptor) of arginine vasopressin. These agents act in the distal collecting ducts of the kidneys, by increasing solute free water excretion and, thus, improving

    Ehrlich ascites cells, in which replication units at the beginning of the S phase started and grew synchronously, were obtained by the following protocol: (1) selection of G{sub 1} cells by zonal centrifugation, (2) hypoxia for 12 h, (3) reaeration, (4) addition of cycloheximide (30 {mu}M) within the first minute after reoxygenation. Studies on the effectiveness of the different steps revealed: (i) G{sub 1} cells reoxygenated after 12 h of hypoxia traverse two succeeding cell cycles high synchronously. This was shown by monitoring the thymidine incorporation rate, the thymidine pulse-labeling index, and the mitotic index. (ii) Cycloheximide, like hypoxia, suppresses replicon initiation in Ehrlich ascites cells without interfering with DNA chain growth and DNA maturation. The reversibility of the suppression is less complete than in the case of hypoxia. This was shown by DNA fiber autoradiography and by analyzing the length distribution of pulse- or pulse/pulse-chase-labeled daughter DNA in alkaline sucrose gradients. The alkaline sedimentation patterns of daughter-strand DNA, pulse labeled immediately after the cycloheximide addition at the end of the elaborated protocol and 1 and 2 h later, indicated synchronous initiation and growth of a homogeneous population of DNA molecules to replicon-sized lengths.

    Ascites caused by hypothyroidism is rare and the pathogenesis is unclear. Several reports have presented cases of progressive ascites with hypothyroidism and elevated tumor markers. We report a 31-year-old female case with massive ascites and elevated serum CA 125 concentrations. The patient had no typical feature of hypothyroidism except an accumulation of ascitic fluid which showed elevated total protein concentration and a high serum-ascites albumin gradient (SAAG). There was no finding of malignancy. Following thyroid hormone replacement, the ascites was completely resolved accompanied by reduced concentrations of serum CA125. In general, primary hypothyroidism with ascites presents with coexisting massive pericardial or pleural effusion. The massive ascites and increased serum CA125 concentrations may have led us to make the incorrect diagnosis of ovarian malignancy. The evaluation of thyroid function is useful to determine the pathology of high-protein ascites or elevated tumor markers, and ascites may be treatable by thyroid replacement therapy.

    Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract with an estimated prevalence of one in 100,000. The typical presentation consists of vague gastrointestinal symptoms with the mucosal involvement of the digestive system. Rarely, it presents as eosinophilic ascites. We report the case of a 22-year-old female who presented with acute onset abdominal pain and ascites. The laboratory studies were remarkable for eosinophilia and the ascitic fluid demonstrated high eosinophilic counts. Push enteroscopy with biopsy supported the diagnosis of eosinophilic gastroenteritis, with likely serosal involvement. Other differential diagnoses were excluded. A prednisone taper along with dietary treatment was initiated. We report complete resolution of symptoms two weeks following the initiation of therapy. Nine months later, she remains asymptomatic without recurrence of ascites. PMID:27843730

While the dose of tolvaptan was thereafter increased to 7.5 mg/day on the 7th hospital day, the ascites still persisted. However, she continued to receive tolvaptan (7.5 mg/day) because the worsening of her subjective symptoms was mild and she wished to do so.

We describe a patient with no prior history of inflammatory bowel or liver disease, presenting with rapid onset gross ascites and scrotal swelling. Further investigations revealed severe hypoalbuminemia and transudative ascitic fluid with normal other liver function tests and a negative liver screen. Computed tomography revealed widespread ascites and pleural effusions with no features of malignancy or portal hypertension, and a small bowel barium series showed features of fistulating small bowel Crohn's disease. An ileo-colonoscopy confirmed the presence of terminal ileal inflammatory stricture.

    A 50-year-old male presented with intractable ascites due to systemic mastocytosis. The diagnosis of systemic mastocytosis was established by histology of the bone marrow which showed mast cell infiltration and fibrosis. Ascites was related to portal hypertension which was documented by esophageal varices at endoscopy and by an increase of wedged-free hepatic venous pressure gradient. Liver biopsy disclosed dense fibrosis of hepatic arterial and portal venule walls, resulting in complete obstruction of some portal radicles. Peliosis hepatis and fibrous deposits in the walls of hepatic venules were also present. Because of intractable ascites and significant malnutrition, a portacaval shunt was performed which cleared ascites and dramatically improved the general condition of the patient.

    Some patients with ascites due to liver cirrhosis become no longer responsive to diuretics. Once other causes of ascites such as portal vein thrombosis, malignancy or infection and non-compliance with medications and low sodium diet have been excluded, the diagnosis of refractory ascites can be made based on strict criteria. Patients with refractory ascites have very poor prognosis and therefore referral for consideration for liver transplantation should be initiated. Search for reversible components of the underlying liver pathology should be undertaken and targeted therapy, when available, should be considered. Currently, serial large volume paracentesis (LVP) and transjugular intrahepatic portasystemic stent-shunt (TIPS) are the two mainstay treatment options for refractory ascites. Other treatment options are available but not widely used either because they carry high morbidity and mortality (most surgical options) rates, or are new interventions that have shown promise but still need further evaluation. In this comprehensive review, we describe the evaluation and management of patients with refractory ascites from the prospective of the practicing physician. PMID:19115470

    Patient: Male, 65 Final Diagnosis: Peritoneal amyloidosis Symptoms: Anasarca • Dyspnea • Orthopnea Medication: — Clinical Procedure: Paracentesis and peritoneal biopsy Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: The clinical manifestations of amyloidosis depend on the type of insoluble protein as well as the location of amyloid deposits in tissues or organs. In the gastrointestinal tract, the small intestine is the most common site of amyloid deposits, whereas peritoneal involvement and ascites are rare. Case Report: We report on a case of ascites due to peritoneal amyloidosis. A 65-year-old patient was admitted to our institution due to anasarca and pulmonary congestion, mimicking heart failure. We started the patient on diuretics and vasodilators. Despite improvement in pulmonary congestion and peripheral edema, his ascites was not reduced. Echocardiogram revealed restrictive cardiomyopathy and a speckle-tracking pattern suggestive of cardiac amyloidosis. Subcutaneous and peritoneal biopsies revealed amyloidosis. Conclusions: Amyloidosis is rare in the peritoneum and is usually asymptomatic. Ascites occurs in only 20% of patients with peritoneal amyloidosis. We searched PubMed using “ascites” and “amyloidosis” and identified only eight case reports of amyloidosis with ascites. Physicians should be particularly careful in heart failure and anasarca cases when ascites is disproportional or not responsive to diuretic treatment. To date, there is no specific treatment for peritoneal amyloidosis. PMID:27353538

    Non hepatic origin of refractory ascites is not a rarity. Hemolytic anemias are known to cause inspissated bile and biliary obstruction. Distal biliary obstruction can lead to biliary perforation. The authors report a case of hereditary spherocytosis leading to inspissated bile causing bile duct perforation and biliary ascites. A high index of suspicion for biliary ascites should be kept in a child with refractory ascites in the setting of progressive ascites with decreasing bilirubin. Ascitic fluid bilirubin analysis will clinch the diagnosis. Surgical repair is the optimal management.

With a diagnosis of chylous ascites, total parenteral nutrition was started. Nine days after starting total parenteral nutrition, cloudiness of ascites decreased, and triglycerides in ascites decreased to 93 mg/dL. Oral intake was restarted, and the patient was discharged on postoperative day 46. Chylous ascites is a rare complication after living-donor liver transplantation for which total parenteral nutrition may be useful. PMID:23294080

    Increased metabolic rates, pulmonary hypertension and cardiac dysfunction are the most important features of the ascites syndrome in broiler chickens. However, the mechanism of cell injury causing the pathogenesis of the syndrome is not clearly understood. Our study aimed to examine the generation of hydroxyl radicals (OH*) in broiler chickens experiencing ascites. The hundred and fifty 1-d-old chickens were purchased from a local hatchery and reared in an open poultry house for 46 d. They were divided at random into three groups and ascites was induced in two groups by exposing them to low temperature or administration of triiodothyronine (T(3)). The third group served as control and was reared normally. Haematological, biochemical and pathological tests were used to determine the incidence of ascites: including total red blood cell (RBC), packed cell volume (PCV), release of alanine transaminase (ALT) and aspartate transaminase (AST) and ratio of right ventricular weight to total ventricular weight (RV/TV). A salicylate hydroxylation method was used to examine the generation of hydroxyl radicals (OH*) in treated groups. TWo hydroxylated salicylic acid metabolites, 2,3- and 2,5-dihydroxy benzoic acid (2,3- and 2,5-DHBA), were measured by HPLC to detect the generation of OH*. An ascites syndrome was observed in T(3) and low-temperature treated groups, as shown by necropsy changes and increases in f RBC, PCV, ALT, AST and the ratio of RV/TV. Concentrations of 2,3- and 2,5-DHBA were increased in groups experiencing ascites compared to control group. It is suggested that reactive oxygen species that is OH* ions, may be involved in the pathogenesis of the ascites syndrome in broiler chickens.

    Epithelial ovarian cancer (EOC) is worldwide the sixth most lethal form of cancer occurring in women. More than one third of ovarian patients have ascites at the time of diagnosis and almost all of them have it when recurrence occurs. Although its effect on tumor cell microenvironment remains poorly understood, its presence is correlated with bad diagnosis. In previous studies, we proposed a novel glycan-based biomarker for the diagnosis of EOC, which showed an improved sensitivity and specificity at any stage of the disease and an improved discrimination between malignant and benign ovarian tumors. In this work, we report for the first time the N-glycome profiles of ascitic fluid from primary serous EOC patients and compare them with the serum N-glycomes of the same patients as well as of healthy controls. N-Glycans were digested from equivalent amount of ascites and serum from 18 EOC patients and from serum of 20 age-matched controls and measured by MALDI-TOF-MS. Ascites N-glycome showed increased antennarity, branching, sialylation and Lewis(X) motives compared to healthy serum. In addition, a correlation was established between ascites volume and degree of sialylation.

    As many as 50% of end-stage cancer patients will develop ascites and associated symptoms, including pain, tiredness, nausea, depression, anxiety, drowsiness, loss of appetite, dyspnea, perceived abdominal bloating, and immobility. Abdominal massage may stimulate lymph return to the venous system and reduce ascites-related symptoms. The purpose of this study was to test the effect of abdominal massage in reducing these symptoms and reducing ascites itself as reflected in body weight. For a randomized controlled design using repeated measures, a sample of 80 patients with malignant ascites was recruited from gastroenterology and oncology units of a medical center in northern Taiwan and randomly assigned to the intervention or the control group. A 15-minute gentle abdominal massage, using straight rubbing, point rubbing, and kneading, was administered twice daily for 3 days. The control group received a twice-daily 15-minute social interaction contact with the same nurse. Symptoms and body weight were measured in the morning for 4 consecutive days from pre- to post-test. In generalized estimation equation modeling, a significant group-by-time interaction on depression, anxiety, poor wellbeing, and perceived abdominal bloating, indicated that abdominal massage improved these four symptoms, with the greatest effect on perceived bloating. The intervention had no effect on pain, tiredness, nausea, drowsiness, poor appetite, shortness of breath, mobility limitation, or body weight. Abdominal massage appears useful for managing selected symptoms of malignant ascites.

    Animal data indicate that ascites is reabsorbed by a lymphatic mechanism and that these vessels are subdiaphragmatic in location. We evaluated the relative role of lymphatics in ascites reabsorption in man by comparing the ascites clearance and plasma appearance rates of intraperitoneally injected radiolabeled albumin to those of intraperitoneally injected labeled autologous red blood cells, which require, owing to their large size, lymphatic removal, in patients with cirrhosis and ascites. To evaluate the location of reabsorption, we repeated these measurements after replacing ascites in the subdiaphragmatic region with 500-1000 ml of intraperitoneally injected air, reasoning that this maneuver should slow or eliminate ascites reabsorption occurring at this site. We found that the transfer rates of albumin and red cells out of ascites were similar and that creation of pneumoperitoneum did not influence these rates. These data confirm that ascites protein reabsorption occurs via a lymphatic mechanism in man. They suggest, however, that these vessels may not be subdiaphragmatic in location.

    A rational approach to the diuretic therapy of ascites is proposed. Fifty-five patients were classified according to their ability to excrete sodium and free water. Patients with a high urinary sodium excretion can be treated by low sodium intake alone. In most patients with a low sodium excretion but high free water clearance, distal diuretics (spironolactone or triamterene) with a low sodium diet will relieve ascites. Patients with low values for sodium excretion and free water clearance also have poor glomerular filtration rate and only a few of these will respond to diuretic therapy. PMID:1234341

    Ascites in systemic lupus erythematosus (SLE) is rarely massive, and either accompanies the typical manifestations of active disease or results from nephrotic syndrome, protein-losing enteropathy, constrictive pericarditis, and conditions unrelated to lupus. Marked ascites has been attributed to chronic lupus peritonitis, characterized by the insidious onset of massive, painless ascites and unrelated to disease activity. Regardless of the etiology, ascites typically has a gradual onset and occurs after a diagnosis of SLE has been made. We describe a young woman presenting with the rapid development of massive ascites as the initial manifestation of SLE.

    Abstract Malignant ascites (MA) is most commonly observed in patients scheduled for epithelial ovarian cancer (EOC) surgery and is supposed as a major risk factor promoting perioperative hemodynamic deterioration. We aimed to assess the hemodynamic consequences of MA on systemic circulation in patients undergoing cytoreductive EOC surgery. This study is a predefined post-hoc analysis of a randomized controlled pilot trial comparing intravenous solutions within a goal-directed algorithm to optimize hemodynamic therapy in patients undergoing cytoreductive EOC surgery. Ascites was used to stratify the EOC patients prior to randomization in the main study. We analyzed 2 groups according to the amount of ascites (NLAS: none or low ascites [<500 mL] vs HAS: high ascites group [>500 mL]). Differences in hemodynamic variables with respect to time were analyzed using nonparametric analysis for longitudinal data and multivariate generalized estimating equation adjusting the analysis for the randomized study groups of the main study. A total of 31 patients in the NLAS and 16 patients in the HAS group were analyzed. Although cardiac output was not different between groups suggesting a similar circulatory blood flow, the HAS group revealed higher heart rates and lower stroke volumes during surgery. There were no differences in pressure-based hemodynamic variables. In the HAS group, fluid demands, reflected by the time to reindication of a fluid challenge after preload optimization, increased steadily, whereas stroke volume could not be maintained at baseline resulting in hemodynamic instability after 1.5 h of surgery. In contrast, in the NLAS group fluid demands were stable and stroke volume could be maintained during surgery. Clinically relevant associations of the type of fluid replacement with hemodynamic consequences were particularly observed in the HAS group, in which transfusion of fresh frozen plasma (FFP) was associated to an improved circulatory flow and reduced

    The decrease of erythrocyte deformability may be one of the predisposing factors for pulmonary hypertension and ascites in broiler chickens. In mammals, the cytoplasmic calcium is a major regulator of erythrocyte deformability. In this study, the erythrocyte deformability was measured, and the precise locations of Ca2+ and Ca2+ -ATPase in the erythrocytes were investigated in chickens with ascites syndrome induced by low ambient temperature. The results showed that ascitic broilers had higher filtration index of erythrocyte compared with control groups, indicating a decrease in erythrocyte deformability in ascitic broilers. The more calcium deposits were observed in the erythrocytes of ascitic broilers compared with those of the age-matched control birds. The Ca2+ -ATPase reactive grains were significantly decreased on the erythrocyte membranes of ascitic broilers. Our data suggest that accumulation of intracellular calcium and inhibition of Ca2+ -ATPase might be important factors for the reduced deformability of the erythrocytes of ascitic broilers.

    Objective: To report a rare cause of cerebrospinal fluid ascites. Methods: A 37-year-old female with history of intracranial hypertension and a ventriculo-peritoneal shunt was referred to liver clinic for evaluation of newly developed ascites. Results: Initially, the cause of ascites was thought to be secondary to a liver etiology. However, this was excluded after a comprehensive evaluation including portal pressure measurements. We determined the ascites to be infected cerebrospinal fluid secondary to a rare commensal organism, Corynebacterium non-Jeikeium, which resolved after removing ventriculo-peritoneal shunt, appropriate antibiotics and conversion to a ventriculo-atrial shunt. Conclusion: Cerebrospinal fluid ascites is a rare complication of VP shunts and since 1976 only 8 cases of Corynebacterium non jk VP shunt infections have been reported in the literature but none associated with ascites. Also this report highlights the beneficial role of transjugular portal pressure measurements in the evaluation of ascites. PMID:27489721

    Effects of coenzyme Q10 (CoQ10) supplementation on growth performance and ascites were studied in broilers. One hundred eighty 1-d-old Arbor Acre male broiler chicks were randomly allocated into 3 groups with 6 replicates each. From d 8, the diets were supplemented with CoQ10 at levels of 0, 20, and 40 mg/kg, respectively. From d 15 to 21, all the chicks were exposed to low ambient temperature (15 to 18 degrees C) to induce ascites. Average feed intake, BW gain, and feed conversion ratio of the broilers during 0 to 3 wk, 3 to 6 wk, and 0 to 6 wk were measured. The results showed that there were no influences observed on broilers' growth performance, but the mortality due to ascites was reduced by CoQ10 supplementation (P < or = 0.05). Erythrocyte osmotic fragility (EOF) was significantly decreased by 40 mg/kg CoQ10 compared with the control, but no significant changes were observed on blood packed cell volume (PCV) among the treatments. Pulmonary arterial diastolic pressure was significantly decreased on d 36, but no significant changes were observed on right ventricular pressure (RVP), pulmonary arterial systolic pressure, and the maximum change ratio of right intraventricular pressure (+/- dp/ dtmax). Ascites heart index (AHI) was significantly decreased by 40 mg/kg CoQ10 supplementation (P < or = 0.05). The results of this study suggested that CoQ10 has a beneficial effect in reducing ascites mortality in broilers, and 40 mg/kg CoQ10 seems to be more effective than 20 mg/ kg CoQ10.

    2008-05-01

    The high growth rate (GR) of contemporary broilers is driven by high rate of feed intake and metabolism. Because of the consequent high oxygen demand, especially when coupled with exposure to high altitude or low temperatures, some broilers fail to regulate oxygen supply and develop the ascites syndrome (AS), which leads to mortality and economic losses. Because of the association between high GR, oxygen demand, and AS, it has been suggested that AS is induced by high GR. If true, further GR enhancement should be avoided because it will increase the proportion of AS-susceptible individuals in contemporary stocks. An alternative hypothesis claims that AS is associated with high actual GR only because the latter increases oxygen demand and that there are genetically AS-resistant broilers that do not develop AS, even when exhibiting high GR. These hypotheses were tested in trials in the years 2002 and 2006, with broilers differing in potential GR: contemporary fast-growing commercial lines and an experimental line derived from commercial broilers in 1986, and (in 2002 only) divergently selected AS-susceptible and AS-resistant lines. A protocol of high-challenge ascites-inducing conditions (AIC) from d 19 was used to distinguish between AS-susceptible and AS-resistant individuals and to determine their GR up to this age. The difference in AS incidence between the divergent lines (93.9 vs. 9.5%) was not explained by the 5% difference in their GR, thus indicating a lack of genetic correlation. In the broiler lines, AS incidence was 31 and 47% in 2002 and 2006, respectively, and 32% in the 1986 slow-growing line. Most broilers that remained healthy under the high-challenge AIC exhibited the same early GR and BW as those that later developed AS. These results, and the relatively high incidence of AS in the slow-growing line, indicate that there is very little, if any, direct genetic association between AS and genetic differences in potential GR, and suggest that AS

    The rapid growth of modern broilers is associated with enhanced appetite and high metabolic rate and, consequently, high O(2) demand. Ascites syndrome (AS) develops in individuals that fail to fully supply the increasing demand for O(2) in their bodies under ascites-inducing conditions (AIC) such as high altitude or low temperatures. The tendency of broilers to develop AS is heritable, but efficacious selection against AS susceptibility (without affecting the normal expression of other important traits) requires identification of indirect selection criteria. In the present study, divergent AS-susceptible (AS-S) and AS-resistant (AS-R) lines were developed to confirm the heritability of AS and to facilitate future detection of criteria for indirect selection against AS susceptibility. The base population consisted of 85 sire families with a mean of 73 progeny per sire, reared in a commercial broiler house under low-challenge AIC (cold environment and pelleted feed). Chicks dying with AS manifestations were designated AS-susceptible, whereas the surviving birds were designated AS-resistant. By the end of the trial (d 48), AS mortality had accumulated to 17.2%, but AS incidence per family (%ASF) ranged from 0 to 49%, with a high heritability (0.57). Parents of 7 families with very high %ASF produced the first generation (S(1)) of the AS-S line, and parents of 7 families with very low %ASF produced the S(1) of the AS-R line. The S(1) males and females reproduced generation S(2) of the selected lines, whereas additional S(1) males were tested under high-challenge AIC (individual cages, cool wind, and pelleted feed). Progeny testing under this high-challenge AIC, followed by sib selection, was repeated in generations S(2) and S(3), resulting in a divergence of 86.6% in the incidence of AS between the AS-S (91.3%) and AS-R (4.7%) lines. The rapid genetic divergence, and family analysis of %ASF suggested that a single or few major genes are responsible for the difference

    Ascites is one of the main features of liver decompensation in cirrhosis, and it is considered to be a dynamic process. In this study, we aimed to (1) measure the reabsorption rate of ascites; (2) evaluate whether these findings were related to features of ascites, hemodynamics, and serum measurements; and (3) examine morphologic changes in the diaphragm of cirrhotic patients. In all, 42 cirrhotic patients with ascites were enrolled in the study to comprise our study group. Using the dextran 70 test, patient ascites volumes and reabsorption rates were measured. Biopsies from the peritoneal side of the diaphragm were also processed for scanning electron microscopy and lymphatic immunohistochemical studies from the cirrhotic patients and control cadavers. The mean ascites reabsorption rate was 4.5 +/- 4.5 (0.18-14.6) mL/min, which correlated significantly with the calculated ascites volume (r = 0.75, P < 0.001). The mean ascites viscosity was 1.07 +/- 0.07 (0.99-1.17) centipoise, which demonstrated a high degree of negative correlation with the ascites reabsorption rate (r = -0.77, P < 0.001). Patients with a history of spontaneous bacterial peritonitis had significantly lesser ascites reabsorption rates than patients without this particular history. The size of lymphatic stomata in scanning electron microscopy depictions was increased, and lymphatic lacunae were dilated in immunohistochemical studies in the cirrhotic patients with ascites. However, these findings were not uniform in every cirrhotic patient with ascites. The volume and viscosity of ascites seem to influence its reabsorption rate. Additionally, previous episodes of spontaneous bacterial peritonitis may be responsible for the decreased ascites reabsorption rates observed in certain patient populations.

The objectives of the current study were to investigate the effect of incidence rate (5%, 10%, 20%, 30% and 50%) of ascites syndrome on the expression of genetic characteristics for body weight at 5 weeks of age (BW5) and AS and to compare different methods of genetic parameter estimation for these traits. 2. Based on stochastic simulation, a population with discrete generations was created in which random mating was used for 10 generations. Two methods of restricted maximum likelihood and Bayesian approach via Gibbs sampling were used for the estimation of genetic parameters. A bivariate model including maternal effects was used. The root mean square error for direct heritabilities was also calculated. 3. The results showed that when incidence rates of ascites increased from 5% to 30%, the heritability of AS increased from 0.013 and 0.005 to 0.110 and 0.162 for linear and threshold models, respectively. 4. Maternal effects were significant for both BW5 and AS. Genetic correlations were decreased by increasing incidence rates of ascites in the population from 0.678 and 0.587 at 5% level of ascites to 0.393 and -0.260 at 50% occurrence for linear and threshold models, respectively. 5. The RMSE of direct heritability from true values for BW5 was greater based on a linear-threshold model compared with the linear model of analysis (0.0092 vs. 0.0015). The RMSE of direct heritability from true values for AS was greater based on a linear-linear model (1.21 vs. 1.14). 6. In order to rank birds for ascites incidence, it is recommended to use a threshold model because it resulted in higher heritability estimates compared with the linear model and that BW5 could be one of the main components of selection goals.

    Background Most patients with advanced ovarian cancer and some patients with advanced endometrial cancer need repeated drainage for malignant ascites. Guidelines to advise those involved in the drainage of ascites are usually produced locally and are generally not evidence-based but mainly based on clinicians’ anecdotal evidence and experience. To discover whether there are ways of managing drains that have been demonstrated to improve the efficacy and quality of the procedure is key in making recommendations which could improve the quality of life (QOL) for women at this critical period of their lives. Objectives To evaluate the benefit and harms of different practices in the management of drains for malignant ascites in the care of women with advanced or recurrent gynaecological cancer. The review aimed to evaluate the evidence regarding the following questions; How long should the drain stay in place? Should the volume of fluid drained be replaced intravenously? Should the drain be clamped to regulate the drainage of fluid? Should any particular vital observations be regularly recorded? Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 1, 2009, Cochrane Gynaecological Cancer Group Trials Register, MEDLINE1950 to February Week 3 2009, Embase 1980 to 2009 Week 8 2009. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of review articles and contacted experts in the field. Selection criteria We searched for randomised controlled trials (RCTs), quasi-RCTs and non-randomised studies that compared a range of interventions for management of multiple paracentesis in women with malignant ascites who had a confirmed histological diagnosis of gynaecological cancer. Data collection and analysis Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. No trials were found and therefore no data were analysed.

    Ascites syndrome is a metabolic disorder in broilers. Mortality due to ascites results in significant economic losses and has a negative impact on animal welfare. It has been shown that genetic factors play a considerable role in susceptibility of birds to ascites, which offers perspectives for selection against this syndrome. The aim of the present study was to evaluate the consequences of alternative selection strategies for BW and resistance to ascites syndrome using deterministic simulation. In addition to the consequences of current selection (i.e., selection for increased BW only) alternative selection strategies including information on different ascites-related traits measured under normal or cold conditions and the consequences of having information on the underlying genes (i.e., MAS) were quantified. Five different breeding schemes were compared based on the selection response for BW, ascites susceptibility, and the rate of inbreeding. Traits investigated in the index as indicators for ascites were hematocrit value (HCT) and ratio of right ventricle to the total ventricular weight of the heart (RV:TV). The results indicated that by ignoring ascites susceptibility in the breeding goal, the gain for BW is 130 g and the birds will become more susceptible to ascites. Testing 50% of the birds under cold temperature conditions and including information of ascites related traits (HCT and RV:TV) measured under normal and cold conditions makes it possible to achieve a relatively high gain for BW (111.4 g) while controlling the genetic level for ascites susceptibility (selection response was 0). The results of scenarios including QTL information of ascites susceptibility showed that QTL information could be used very effectively in controlling ascites susceptibility.

    The early phase of the ConA-induced inflammatory ascites was studied, with special reference to histamine. Concanavalin A (ConA), a cell-surface binding lectin was injected i.p. (25 mg/kg bw) to mice. After 1 h the animals were killed, the ascitic fluid collected and measured. Other agents were injected s.c., 10 min before the ConA-challenge. Exogenous histamine markedly inhibited the ConA-induced ascites. Release of endogenous vasoactive agents from the mast cells by Compound 48/80 had a similar, but slight effect. Cromolyn, a mast cell stabilizing agent, and chloropyramine, a histamine H1 receptor antagonist was ineffective. Although histamine increases endothelial permeability, it did not enhance the formation of ascitic fluid, on the contrary, it inhibited the ConA-induced ascites, presumably due to its known hypotonic effect. It is concluded that ConA-induced ascites is not mediated by mast cell histamine.

    Ascites syndrome is a metabolic disorder found in modern broilers that have insufficient pulmonary vascular capacity. Commercial breeding programs have heavily focused on high growth rate, which led to fast-growing chickens, but as a negative consequence, the incidence of ascites syndrome increased. However, not all birds with a high growth rate will suffer from ascites syndrome, which might indicate a genetic susceptibility to ascites. Information on blood gas parameters measured early in life and their relation to ascites susceptibility is expected to contribute to identification on the cause of ascites syndrome. In this study, several physiological parameters, such as blood gas parameters [pH, partial pressure of CO(2) in venous blood (pvCO(2)), and partial pressure of O(2) in venous blood], hematocrit, electrolytes (Na(+), Ca(2+), and K(+)), metabolites (lactate and glucose), were measured at d 11 to 12 of age from 100 female and 100 male broilers. From d 14 onward, the birds were challenged to provoke the development of ascites syndrome. Our results showed that high pvCO(2) values together with low pH values (males) or high pH values (females) in the venous blood of juvenile broilers coincided with ascites. Therefore, blood pvCO(2) and pH in both juvenile male and female broilers seem to be critical factors in ascites pathophysiology and can be used as phenotypic traits to predict ascites susceptibility in juvenile broilers at d 11 to 12. A prediction model was built on a subpopulation of the broilers without any loss in sensitivity (0.52) and specificity (0.78) when applied to the validation population. The parameter sex was included in the prediction model because levels of pvCO(2) and pH that associated with ascites susceptibility are different between males and females. Commercial breeders can include these phenotypic traits in their genetic selection programs to reduce the incidence of ascites syndrome.

    Ascites syndrome is still a problem for chicken industry in various parts of the world. Despite the intensive investigations of this syndrome for many years, its pathogenesis remains unclear. The objective of this study was to analyze the difference in hepatic proteomics between ascites and healthy broilers by two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS). Changes of biochemical parameters of liver and blood were also determined. The results indicated that red blood cell counts (RBC), hematocrit (HCT) and haemoglobin (HGB) of ascites broilers were significantly greater than healthy broilers. Hepatic malondialdehyde (MDA) level of ascites broilers was significantly increased, and the activity of total superoxide dismutase (T-SOD) was significantly decreased. Hepatic lactic acid (LD) level of ascitic broilers were significantly lower than healthy ones. Serum glucose and cholesterol level of ascites broilers were significantly increased, and serum globulin level was significantly decreased in ascites broilers. There was no significant difference in triglyceride (TG) and blood urea nitrogen (BUN) level. The activity of liver hexokinase (HK) and succinodehydrogenase (SDH) in ascites broilers was significantly decreased, and there was no significant difference in the activity of liver pyruvate kinase (PK) and Na+-K+-ATPase. The hepatic proteomics analysis showed that 18 proteins expression difference were identified between ascites and healthy broilers. These proteins were mainly involved in: 1) cytoskeleton; 2) glucose, lipids and amino acid metabolism; 3) cell secretion; 4) cell apoptosis; 5) signal transduction; 6) immune and inflammatory response; and 7) cellular redox homeostasis. Mitochondrial isoform phosphoenolpyruvate carboxykinase (M-PEPCK) mainly participates in gluconeogenesis of chicken liver. In conclusion, liver oxidative damage was significantly aggravated, but

    2012-01-01

    Resistance and tolerance are two complementary mechanisms to reduce the detrimental effects of parasites, pathogens, and production diseases on host performance. Using body weight and ascites data on domesticated chicken Gallus gallus domesticus, we demonstrate the use of random regression animal model and covariance functions to estimate genetic parameters for ascites resistance and tolerance and illustrate the way individual variation in resistance and tolerance induce both genotype re-ranking and changes in variation of host performance along increasing ascites severity. Tolerance to ascites displayed significant genetic variance, with the estimated breeding values of tolerance slope ranging from strongly negative (very sensitive genotype) to weakly negative (less sensitive). Resistance to ascites had heritability of 0.34. Both traits are hence expected to respond to selection. The two complementary defense strategies, tolerance and resistance, were genetically independent. Ascites induced changes to the correlations between ascites resistance and body weight, with the genetic correlations being weak when birds were ascites-free but moderately negative when both healthy and affected birds were present. This likely results because ascites reduces growth, and thus high ascites incidence is genetically related to low adult body weight. Although ascites induced elevated phenotypic and genetic variances in body weight of affected birds, heritability displayed negligible changes across healthy and affected birds. Ascites induced moderate genotype re-ranking in body weight, with the genetic correlation of healthy birds with mildly affected birds being unity but with severely affected birds 0.45. This study demonstrates a novel approach for exploring genetics of defense traits and their impact on genotype-by-environment interactions. PMID:22670223

    This study reports novel insight into the aetiology of pulmonary hypertension and ascites in broiler chickens. The scope of measurements was focused on anatomical and functional parameters, and blood flow patterns in leghorns (resistant to ascites), fast-growing broilers (susceptible to ascites), broilers developing ascites, and ascitic broilers evaluated in vivo using echocardiography, and further examined in the context of postmortem findings. Both, in vivo observed features and postmortem findings, showed clear differences between broilers and leghorns, and between normal and ascitic broilers. Abnormalities in the heart chamber geometry and blood flow patterns were detected upon echocardiographic examination in all ascitic broilers. Right and left atrio-ventricular (AV) valve regurgitation were common findings in ascitic broilers and some apparently normal broilers, with left AV valve insufficiency being a predominant feature with respect to degree and frequency of occurrence. Blood flow disturbances were not detected in leghorns. Left ventricular fractional shortening (functional parameter) was considerably reduced (P < 0.01) in ascitic birds (mean: 21.7 +/- 2.0 SE) in comparison with normal broilers (mean: 39.1 +/- 3.6 SE), or leghorns (mean: 43.3 +/- 2.4 SE). The presented findings indicate that pathological and functional changes in the left ventricle and atrium play a significant role in the pathogenesis of ascites in broilers. Severe dilation of the left atrium and pulmonary veins seen on postmortem examination, as well as regurgitant blood flow in the left atrium, demonstrated by Doppler study in ascitic birds, provide evidence that chronically elevated pressure in the left atrium is involved in the aetiology of pulmonary hypertension and ascites in fast-growing broilers.

    Acute kidney injury in the setting of ascites and cirrhosis is a medical emergency characterized by significant morbidity and mortality. Clinicians other than gastroenterologists are often the front line against acute kidney injury for patients with ascites. Owing to the specifics of cirrhotic physiology, the treatment and prevention of acute kidney injury in the setting of ascites has unique features, widespread knowledge of which will benefit our patients with cirrhosis. Early detection and treatment of infection, maximization of cardiac output, and avoidance of medications that limit cardiorenal adaptations to arterial underfilling are part of a multipronged strategy to protect the renal function of our patients with cirrhosis and ascites.

    (1) Pulmonary hypertension syndrome followed by ascites is a metabolic disorder in broilers that occurs more often in fast-growing birds and at cool temperatures. (2) Knowledge of the genetic relationships among ascites-related traits and performance traits like carcase traits or feed efficiency traits is required to design breeding programmes that aim to improve the degree of resistance to ascites syndrome as well as production traits. The objective of this study was to estimate these genetic correlations. (3) Three different experiments were set up to measure ascites-related traits (4202 birds), feed efficiency traits (2166 birds) and carcase traits (2036 birds). The birds in different experiments originated from the same group of parents, which enabled the estimation of genetic correlations among different traits. (4) The genetic correlation of body weight (BW) measured under normal conditions and in the carcase experiment with the ascites indicator trait of right ventricle to total ventricle ratio (RV:TV) measured under cold conditions was 0.30. The estimated genetic correlation indicated that single-trait selecting for BW leads to an increase in occurrence of the ascites syndrome but that there are realistic opportunities of multi-trait selection of birds for improved BW and resistance to ascites. (5) Weak but positive genetic relationships were found between feed efficiency and ascites-related traits suggesting that more efficient birds tend to be slightly more susceptible to ascites. (6) The relatively low genetic correlation between BW measured in the carcase or in the feed efficiency experiments and BW measured in the ascites experiment (0.49) showed considerable genotype by environment interaction. (7) These results indicate that birds with high genetic potential for growth rate under normal temperature conditions have lower growth rate under cold-stress conditions due to ascites.

    2013-01-01

    Pulmonary arterial hypertension (PAH) syndrome in broilers (also known as ascites syndrome and pulmonary hypertension syndrome) can be attributed to imbalances between cardiac output and the anatomical capacity of the pulmonary vasculature to accommodate ever-increasing rates of blood flow, as well as to an inappropriately elevated tone (degree of constriction) maintained by the pulmonary arterioles. Comparisons of PAH-susceptible and PAH-resistant broilers do not consistently reveal differences in cardiac output, but PAH-susceptible broilers consistently have higher pulmonary arterial pressures and pulmonary vascular resistances compared with PAH-resistant broilers. Efforts clarify the causes of excessive pulmonary vascular resistance have focused on evaluating the roles of chemical mediators of vasoconstriction and vasodilation, as well as on pathological (structural) changes occurring within the pulmonary arterioles (e.g., vascular remodeling and pathology) during the pathogenesis of PAH. The objectives of this review are to (1) summarize the pathophysiological progression initiated by the onset of pulmonary hypertension and culminating in terminal ascites; (2) review recent information regarding the factors contributing to excessively elevated resistance to blood flow through the lungs; (3) assess the role of the immune system during the pathogenesis of PAH; and (4) present new insights into the genetic basis of PAH. The cumulative evidence attributes the elevated pulmonary vascular resistance in PAH-susceptible broilers to an anatomically inadequate pulmonary vascular capacity, to excessive vascular tone reflecting the dominance of pulmonary vasoconstrictors over vasodilators, and to vascular pathology elicited by excessive hemodynamic stress. Emerging evidence also demonstrates that the pathogenesis of PAH includes characteristics of an inflammatory/autoimmune disease involving multifactorial genetic, environmental, and immune system components.

    An investigation of the efficacy of astatine-211-tellurium colloid for the treatment of experimental malignant ascites in mice reveals that this ..cap alpha..-emitting radiocolloid can be curative without causing undue toxicity to normal tissue. By comparison, negatron-emitting phosphorus-32 as colloidal chromic phosphate had no antineoplastic activity. The most compelling explanation for this striking difference is the dense ionization and short range of action associated with ..cap alpha..-emission. These results have important implications for the development and use of ..cap alpha..-emitters as radiocolloid therapy for the treatment of human tumors.

    Some cytochemical and immunocytochemical investigations were carried out on actively growing Yoshida ascites sarcoma cells. These cells displayed an intense granular alpha-naphthylacetate esterase (ANAE) staining while the alpha-naphthylbutyrate esterase (ANBE) reaction was in part fluoride-sensitive and marked particularly in the large-size malignant cells. Acid phosphatase as well as peroxidase activities were not detected. The lack of immunoreactive lysozyme and alpha 1-antitrypsin suggested a poor differentiation of the above-mentioned tumor cells, but fibronectin and S-100 protein where highly expressed, as in tumors arising from the mononuclear phagocyte system.

CCA is a rare condition, and there is limited understanding of its pathophysiology and treatment options. We also review the patient’s treatment course mitigated with octreotide and total parenteral nutritional support, as there are no current established guidelines for CCA. Early recognition of possible association with Ehlers-Danlos syndrome is important for quick intervention and successful management of pediatric patients. PMID:28119937

    Ascites is more difficult to detect when only a small quantity is present. The aim of this pilot study was to determine the optimal bowel sound characteristics in order to distinguish no ascites from small-volume ascites by advanced processing of bowel sound wave patterns. This analysis results in the definition of the normal range of bowel sound patterns, thus providing a novel, simple, and noninvasive way of determining on abnormal pattern, which may reflect presence of small volume ascites. Cirrhotic patients with radiologically proven small-volume ascites and a control group were subjected to bowel sound recordings. The latter were analyzed using a denoising wavelet transform-based filter and a higher-order crossings-based technique in a blinded fashion for linearly distinguishing the two classes. Scatter plots of third-order zero crossings reflect distinct changes seen in the denoised bowel sound pattern between patients and controls due to altered transmission path, providing a distinct separation of all cirrhotic patients with small ascites from controls (P < 0.0001). We conclude that the proposed bowel sounds analysis appears to provide new information regarding the changes of the bowel sound patterns due to the presence of small-volume ascites, potentially contributing towards a safe, effective, noninvasive, and easily implemented alternative method for the diagnosis of small volume ascites at the bedside.

    Cirrhosis is a major cause of morbidity and mortality worldwide with liver transplantations as it only possible cure. In the face of a significant organ shortage many patients die waiting. A major complication of cirrhosis is the development of portal hypertension and ascites. The management of ascites has barely evolved over the last hundred years and includes only a few milestones in our treatment approach, but has overall significantly improved patient morbidity and survival. Our mainstay to ascites management includes changes in diet, diuretics, shunt procedures, and large volume paracentesis. The understanding of the pathophysiology of cirrhosis and portal hypertension has significantly improved in the last couple of decades but the changes in ascites management have not seemed to mirror this newer knowledge. We herein review the history of ascites management and discuss some its current limitations. PMID:27729954

    Borderline ovarian tumors are benign but relatively large tumors that are often initially mistaken as ovarian cancers. We report three cases of stage I borderline ovarian tumors having massive ascites that we (preoperatively) suspected of being advanced ovarian cancer. The three patients (35, 47, and 73 years old) reported feeling fullness of the abdomen before consulting their gynecologist. By CT scan, they were diagnosed with a pelvic tumor accompanied by massive ascites, the diameters of which were 11, 20, and 11 cm, respectively. Postsurgical pathology showed all were stage I borderline ovarian tumors without dissemination; two were mucinous and one was serous. The amount of ascites was 6,300, 2,600, and 3,600 mL, respectively, and was serous in all. Cytodiagnosis of the ascites found that one was positive for tumor cells and two were negative. After resection of the mass, the ascites disappeared in all three cases. No pleural effusion was present at any time. The literature is reviewed concerning ascites and pleural effusions linked to ovarian tumors, and a supposition is forwarded of why pleural effusion presents sporadically in these cases.

    Ascites is a multi-faceted disease commonly observed in fast growing broilers, which is initiated when the body is insufficiently oxygenated. A series of events follow, including an increase in pulmonary artery pressure, right ventricle hypertrophy, and accumulation of fluid in the abdominal cavity and pericardium. Advances in management practices along with improved selection programs have decreased ascites incidence in modern broilers. However, ascites syndrome remains an economically important disease throughout the world, causing estimated losses of $100 million per year. In this study, a 60 K Illumina SNP BeadChip was used to perform a series of genome wide association studies (GWAS) on the 16th and 18th generation of our relaxed (REL) line descended from a commercial elite broiler line beginning in 1995. Regions significantly associated with ascites incidence were identified on chromosome 2 around 70 megabase pairs (Mbp) and on chromosome Z around 60 Mbp. Five candidate single nucleotide polymorphisms (SNP) were evaluated as indicators for these 2 regions in order to identify association with ascites and right ventricle to total ventricle weight (RVTV) ratios. Chromosome 2 SNP showed an association with RVTV ratios in males phenotyped as ascites resistant and ascites susceptible (P = 0.02 and P = 0.03, respectively). The chromosome Z region also indicates an association with resistant female RVTV values (P = 0.02). Regions of significance identified on chromosomes 2 and Z described in this study will be used as proposed candidate regions for further investigation into the genetics of ascites. This information will lead to a better understanding of the underlying genetics and gene networks contributing to ascites, and thus advances in ascites reduction through commercial breeding schemes.

    Ovarian cancer (OC) is the eighth most lethal gynecological malignancy and the main cause of gynecological cancer death in industrialized countries. Malignant ascites is often found in OC, with about 10% of patients suffering from recurrent OC. Tumor cells in OC-associated malignant ascites promote disease recurrence and patient mortality is mainly associated with widespread metastasis to serosal surfaces and accompanying peritoneal effusions. Targeted therapies have recently been developed as novel therapeutic options for malignant ascites. The tri-functional anti-epithelial cell adhesion molecule and anti-cluster of differentiation 3 monoclonal antibody catumaxumab has been assessed in the therapy of malignant ascites, and proven to significantly reduce the ascitic flow rate when applied into the peritoneal cavity. The anti-angiogenic targeted agent bevacizumab has also shown good effects in the symptomatic treatment of malignant ascites, significantly prolonging the time until the next paracentesis. Vascular endothelial growth factor (VEGF) Trap, or aflibercept, is a fusion protein that inhibits VEGF-receptor binding. Aflibercept has proven to be effective in reduction of ascites, diminishing clinical symptoms of ascites and prolonging the time to next paracentesis. All three agents we review in the present article are effective in symptomatic control of ascites, leading to a rapid reduction of effusion and prolonging the time interval between paracenteses. However, no improvement in overall survival was observed in any of the clinical trials reported. We, thus, conclude that further investigations on larger patient series are needed to clarify whether the reduction of ascites by these targeted agents leads to a prolongation in tumor-related survival or not.

    The concept that host immunization may be achieved by heat-induced antigenic modifications of cancer cells and/or the release of immunogenic products by dead or dying tumor cells following in vitro heating was examined. Ehrlich ascites cells were used, inasmuch as it was claimed that in vitro hyperthermia increased the immunogenicity of these cells. Tumor cell populations of different viability were obtained by heating Ehrlich cells at 42.5 degrees, 45 degrees, or 60 degrees C. Viable and nonviable cells were separated by Ficoll-Hypaque density centrifugation; viable nonreplicating cells were obtained by treatment with mitomycin C. Cell populations of different viability after heating were left to die slowly over 3 days at 37 degrees C. Swiss TO mice were then given injections of the treated cells and/or medium. No survival benefit occurred in mice inoculated with any of these different components and then challenged with viable tumor cells. Injection of irradiated cells, however, did produce host immunity. Similarly, D23 rat hepatoma ascites cells produced host immunity after 15,000 rad but not after heating. The claim that in vitro hyperthermia increases the immunogenicity of tumor cells was not confirmed.

    Background Renal cysts are common in old patients, and usually remain untreated. Giant renal cyst measuring more than 15 cm in diameter and containing more than 1500 mls of serous fluid are rarely seen. We report a case of a 75-year-old man with a giant right renal cyst. Case presentation A 75-year-old man presented with a five years history of suprapubic pain, abdominal distension. He had no urological symptoms. Physical examination revealed a distended abdomen with shifting dullness. Routine hematology, biochemistry, and serum tumor markers were within normal limits. Erroneously diagnosed as ascites on ultrasonographic examination. Abdominal paracentesis of supposed ascites was performed. The diagnosis of giant renal cyst was finally made by Computed tomography (CT) and patient underwent continuous percutaneous catheter drainage with negative pressure, whereby 8 liters of fluid were removed with negative cytology. Subsequent Computed tomography after 6 months revealed disparition of the cysts, and the patient remained asymptomatic. Conclusion Giant renal cysts are uncommon; we conclude that the CT remains the best exam in patients evaluated for giant renal cyst. This to the best of our knowledge is the largest renal cyst in the medical literature. Studies are needed with particular attention to the factors associated with renal cyst enlargement.

    A flying spot ultraviolet microscope, employing a fast scan and pulsed operation of the raster, has been used to induce radiation damage in ascites tumor slide cultures, and to study by time-lapse cinematography the progressive stages of cell damage. The cells observed came from a strain (EF7) of the Ehrlich ascites carcinoma. Irradiated cells were found to show a characteristic syndrome of damage, involving blebbing at the cell surface, while control cells in the adjacent areas of the preparation remained unchanged. The end of the blebbing period is marked by swelling of the cells, and the time taken for this phenomenon to occur was used as a measure of the severity of the damage. It was found that the time required for swelling is dependent on the size of the dose employed, as well as on the sensitivity of the cells. This latter sensitivity was found to decline as the physiological age of the tumor increased. If ultraviolet illumination below 255 mµ is excluded, no symptoms of damage occur, even when very large doses are used. These observations are discussed in relation to the nature of the system in the cell which is affected. PMID:13654439

    Background The purpose of this study was to determine risk factors for development of malignant ascites and its prognostic significance in patients with pancreatic cancer. Methods A prospective database was queried to identify patients with pancreatic cancer who develop ascites. Stage at presentation, size, and location of primary tumor, treatment received and length of survival after onset of ascites were determined. Results A total of 15 patients were identified. Of which 4 patients (1 stage II, 3 stage III) underwent pancreaticoduodenectomy and manifested with ascites 2, 3, 24 and 47 months after surgery (tumor size 2.9 ± 1.32 cm). All but one of the remaining 11 patients (tumor size 4.4 ± 3.38 cm) presented with metastatic disease, and all developed malignant ascites 9 months after diagnosis, dying 2 months later. Resected patients lived longer before the onset of ascites, but not after. Conclusion Once diagnosed, ascites in pancreatic cancer patients heralds imminent death. Limited survival should be considered when determining the aggressiveness of further intervention. PMID:16569225

    This study examined the putative role of blood vessel pathology in the development of ascites in broilers. Major blood vessels (aorta, brachiocephalic arteries, pulmonary arteries, and vena cava) from normal commercial male broiler chickens, and broilers that developed congestive heart failure (CHF) with or without ascites were subjected to gross and microscopic examination. On cross-section, grossly, the arteries from normal broilers and those showing dilated cardiomyopathy without ascites appeared circular, with firm wall tone characteristic of the normal artery. In contrast, the arteries from ascitic broilers appeared flaccid and lacked elasticity, which was evidenced by collapsing, ellipsoid cross-sectional arterial lumen owing to the structural weakness of the arterial walls. Microscopically, ascitic broilers showed thinning or occasionally total loss of elastic elements in the arterial wall, and reduced network density of the structural matrix of the vascular wall, as well as increased thickness of fibers in vena cava. The structural changes seen in the major arteries from ascitic broilers are maladaptive, and as such would definitively impose an increased hemodynamic burden on the already failing heart pump. The changes in veins are indicative of pathological remodeling conducive to increased permeability of the vascular wall, particularly in the situation when a poorly distensible structure is further subjected to wall stress associated with increased pressure and volume overload. Taken together, increased hemodynamic burden and reduced structural density of the venous wall constitute conditions conducive for seepage and accumulation of ascitic fluid.

    AIM: To measure plasma D-dimer levels in cirrhotic patients with and without ascites, assessing the effect of ascites resolution in D-dimer concentration. METHODS: Seventy consecutive cirrhotic patients (M = 44, F = 26, mean age 65 years, SD ± 13), observed from October 2005 to March 2006 were enrolled. Circulating D-dimer levels were measured using a latex-enhanced, immunoturbidimetric test. In patients with ascites (n = 42) the test was repeated after ascites resolution. RESULTS: Ascites was present in 42 patients (group A) and absent in 28 (group B). Group A patients had more advanced liver disease. Hepatocellular carcinoma (HCC) was diagnosed in 14 patients and was more frequent in group B. Above normal range D-dimers were found in 45/70 patients. High D-dimers were more frequent in group A than in group B (P = 0.001). High D-dimers were associated with presence of HCC (P = 0.048) only in group B. After ascites resolution, obtained in all patients, mean D-dimer values decreased in those 34 patients with high basal levels (P = 0.007), returning to normal in 17. CONCLUSION: In patients with liver cirrhosis, ascites and HCC are the main factors associated with increased fibrinolytic activity. PMID:18330946

    Genetic selection based on rapid growth rates, improved feed conversion, and increased body weights has led to a predisposition to ascites in broiler populations. Sire-family selection was applied to a commercial elite line to produce divergent lines of ascites-resistant (RES) and ascites-susceptible (SUS) broilers by the 8th generation. One objective of this research was to determine the effects of hypobaric hypoxia on gut morphology in these genetic lines. In two separate trials, pedigree broiler chickens were randomly assigned to cages in a hypobaric chamber (simulated 2,900 m above sea level) or a matching local altitude chamber (390 m above sea level). Ascites incidence was characterized by heart enlargement and fluid accumulation in the abdominal cavity. At the end of the study on d 42, all surviving birds were killed and evaluated for the presence of ascites and 2-cm sections from the duodenum and lower ileum were collected from 5 chickens per line, per altitude for each trial for morphometric analysis. At a high altitude, ascites incidence was lower in the RES line (20.9 and 3.7%) than in the SUS line (86.4 and 66.9%, Trials 1 and 2, respectively). No ascites was observed at a local altitude. Under hypoxic conditions, duodenum villus surface area was higher (P < 0.05) in the RES line (181.3 +/- 16.8 and 219 +/- 10.9 microm) compared with the SUS line (130.1 +/- 10.5 and 134.3 +/- 9.3 microm; Trials 1 and 2, respectively). No differences in ileum villus morphology were observed for any of the parameters measured. The reduced surface area in the duodenum of birds selected for ascites susceptibility suggests reduced enteric function and may provide clues as to why these birds have increased incidence of ascites.

    During the course of ascites development in broilers, many factors can interact to cause hypoxia. To counteract hypoxia, birds with ascites develop greatly increased hematocrit and red cell counts. Increasing hematocrits result in more viscous blood. Prostaglandins are involved in the regulation of constriction and dilation of pulmonary blood vessels and in the formation of blood clots. Dietary aspirin, a prostaglandin inhibitor, was used in an attempt to promote vasodilation and inhibit blood clotting in broilers, with the objective of determining the effect of aspirin on ascites progression. The experimental design consisted of two trials with a total of 1,360, 1-d-old male broiler chicks, which were placed at either local altitude (390 m above sea level) or in a hypobaric chamber that simulated an altitude of 2,900 m above sea level. At each elevation, five dietary treatments were employed: [control, 0.025% crystalline acetylsalicylic acid (aspirin), 0.05% aspirin, 0.10% aspirin, and 0.20% aspirin]. Bird and feed weights were recorded weekly. At the end of 5 wk, blood samples and organ weights were collected, and all birds were examined for signs of ascites. In both trials, birds raised at high altitudes were significantly lighter, had a higher incidence of ascites, and had differences in hematology, compared with birds raised at local elevation. Only in Trial 2, however, did dietary aspirin appear to have any effect on ascites incidence. At the 0.20% aspirin level, a reduction in ascites incidence approached significance compared with controls (34% vs. 56%, P < or = 0.06). Unfortunately, birds fed 0.20% aspirin also were significantly (P < or = 0.01) lighter than controls. Because slowing growth rate is known to reduce ascites, this decrease in BW may have been partially responsible for any beneficial effect on ascites development and progression obtained through feeding aspirin.

    Breeding against a production disease is complicated by multiple relationships between productivity, disease, and environment. Ascites in broilers is such a disease. The combination of the reasonably well understood etiology (a physiological/pathological cascade due to inadequate oxygen supply) and the practical relevance makes ascites a relevant case for demonstrating and partly revealing these complex relationships. Chickens (n = 2,788) were tested in an ascites-challenging (cold) environment. Genetic analysis of mortality and pathology in combination with performance and physiological traits (especially blood gas traits) revealed ample opportunities for selection against ascites expression. The genetic correlation structure indicated that different mortality traits and pathology traits roughly represent one common characteristic. Direct selection against pathology is more effective than selection on the basis of growth or blood gas traits. The observed negative correlation (-0.26) between productivity and ascites was unexpected. From the etiology of ascites (inadequate supply of oxygen relative to the demand), a positive (unfavorable) correlation was expected. To demonstrate that the actual disease occurrence caused this apparent contradiction, the data from the undiseased subpopulation were reanalyzed. In the undiseased subpopulation, the genetic correlation between productivity and ascites was positive (0.29). This discrepancy was confirmed by comparing regression of ascites expression on actual performance with regression of ascites on independently assessed performance breeding values. The lability of the genetic correlation was explained from complex interactions between productivity, disease susceptibility, and actual occurrence of the disease. The revealed mechanism can be generalized to other production-related diseases and results in systematically lower genetic correlations between disease and productivity. It was inferred that genetic correlations

    Postoperative ascites is a very rare complication of laparoscopic surgery. Significant iatrogenic injuries to the bowel, the urinary tract, and the lymphatic system should be excluded promptly to avoid devastating results for the patient. In some cases, in spite of investigating patients extensively, no definitive causative factor for the accumulation of fluid can be identified. In such cases, idiopathic allergic or inflammatory reaction of the peritoneum may be responsible for the development of ascites. We present a case of ascites of an unknown origin in a young female patient following a laparoscopic appendicectomy. PMID:24822146

    Malignant ascites presents a considerable clinical challenge to the management of ovarian cancer, but also provides a wealth of opportunities for translational research. The accessibility of ascitic fluid and its cellular components make it an excellent source of tumour tissue for the investigation of prognostic and predictive biomarkers, pharmacodynamic markers and for molecular profiling analysis. In this Opinion article, we discuss recent advances in our understanding of its pathophysiology, the development of new methods to characterize its molecular features and how these findings can be used to improve the treatment of malignant ascites, particularly in the context of ovarian cancer.

    We report two cases of gastric varices complicated by massive ascites that disappeared after balloon-occluded retrograde transvenous obliteration (B-RTO). The first patient had progressive gastric varices that continued to enlarge even after three episodes of esophagogastric variceal bleeding, and the second patient was admitted to our hospital because of the bleeding from gastric varices. After B-RTO procedures in both patients, significant improvement of the ascites, hepatic function reserve, and hypoalbuminemia was observed. Although further experience is needed, our experience points to the likelihood of the amelioration of ascites after B-RTO.

    The rhythms of cell proliferation and DNA synthesis were studied in a hypotetraploid strain of Ehrlich's ascites tumor (EAT) and compared with data obtained previously on the hyperdiploid strain of EAT. Eighty-five noninbred male albino mice were used. An injection of tritium-thymidine, with specific radioactivity of 4.1 Ci/mmole, was given to the mice one hour before sacrifice. The results obtained are presented; it is shown that the number of DNA-synthesizing cells in the hypotetraploid strain during the 5th and 6th days of growth of EAT was 503 and 479 /sup 0//00, respectively. Fluctuations of the radioactive index during these days were not significant. Only a significant fall in the radioactive index toward noon on the seventh day of development of the hypotetraploid strain of EAT was observed.

    Ehrlich ascites-tumour cells were investigated with regard to their stability to transport L-lactate by measuring either the distribution of [14C]lactate or concomitant H+ ion movements. The movement of lactate was dependent on the pH difference across the cell membrane and was electroneutral, as evidenced by an observed 1:1 antiport for OH- ions or 1:1 symport with H+ ions. 2. Kinetic experiments showed that lactate transport was saturable, with an apparent Km of approx. 4.68 mM and a Vmax. as high as 680 nmol/min per mg of protein at pH 6.2 and 37 degrees C. 3. Lactate transport exhibited a high temperature dependence (activation energy = 139 kJ/mol). 4. Lactate transport was inhibited competitively by (a) a variety of other substituted monocarboxylic acids (e.g. pyruvate, Ki = 6.3 mM), which were themselves transported, (b) the non-transportable analogues alpha-cyano-4-hydroxycinnamate (Ki = 0.5 mM), alpha-cyano-3-hydroxycinnamate (Ki = 2mM) and DL-p-hydroxyphenyl-lactate (Ki = 3.6 mM) and (c) the thiol-group reagent mersalyl (Ki = 125 muM). 5. Transport of simple monocarboxylic acids, including acetate and propionate, was insensitive to these inhibitors; they presumably cross the membrane by means of a different mechanism. 6. Experiments using saturating amounts of mersalyl as an "inhibitor stop" allowed measurements of the initial rates of net influx and of net efflux of [14C]lactate. Influx and efflux of lactate were judged to be symmetrical reactions in that they exhibited similar concentration dependence. 7. It is concluded that lactate transport in Ehrlich ascites-tumour cells is mediated by a carrier capable of transporting a number of other substituted monocarboxylic acids, but not unsubstituted short-chain aliphatic acids.

    Liver transplantation preserving the retrohepatic inferior vena cava, the so-called piggyback technique, is becoming more frequently used because it avoids caval cross-clamping during the anhepatic phase of surgery. However, hepatic venous outflow blockade causing ascites seems to be less infrequent after piggyback than with cavo-caval anastomosis. We report a 62-year-old patient who underwent liver transplantation using the piggyback technique and developed a stenosis in the anastomosis between the hepatic veins and the inferior vena cava leading to severe postoperative ascites. Ascites was unresponsive to diuretic therapy and was associated with renal function impairment. Since the etiology of the stenosis was mechanical (torsion), percutaneous transluminal angioplasty was unsuccessful. Finally, an autoexpandable prosthesis was placed across the anastomosis resulting in rapid and permanent (3 years of follow-up) resolution of ascites.

    A genome-wide SNP survey was used to identify chromosomal regions that showed linkage disequilibrium with respect to ascites susceptibility and ventricular hypertrophy in an F2 cross between previously described ascites-resistant and -susceptible lines. Variable number tandem repeats were used to obtain genotype data to further characterize these regions. A region on chromosome 9 (12 to 13 Mbp in 2011 assembly) shows association with ascites in the ascites lines and in several commercial broiler breeder lines with a significant sex effect. There are 2 candidate genes, AGTR1 (an angiotensin II type 1 receptor) and UTS2D (urotensin 2 domain containing), in this region that have been associated with hypertension and hypoxic response in mammals.

    Previously, we reported a genome wide association study (GWAS) that had shown association of a region between 11.8 and 13.6 Mbp on chromosome 9 with ascites phenotype in broilers. We had used microsatellite loci to demonstrate an association of particular genotypes for this region with ascites in experimental ascites lines and commercial broiler breeder lines. We identified two potential candidate genes, AGTR1 and UTS2D, within that chromosomal region for mediating the quantitative effect. We have now extended our analysis using SNPs for these genes to assess association with resistance or susceptibility to ascites in these same broiler lines. Surprisingly, in contrast to our previous GWAS and microsatellite data for this region, we find no association of the SNP genotypes or haplotypes in the region suggesting that the two genes might have limited association with the disease phenotype.

    Ascites is a metabolic disorder of modern broilers that is distinguished by cardiopulmonary insufficiency in the face of intense oxygen demands of rapidly growing tissues. Broilers with ascites exhibit sustained elevation of pulmonary arterial pressure and right ventricular hypertrophy, the end result of which is heart failure. It has been shown that mitochondrial function is impaired in broilers with ascites. In the current study, mitochondrial matrix protein levels were compared between ascites-resistant line broilers and ascites-susceptible line broilers with and without ascites using two-dimensional (2-D) gel electrophoresis. One hundred seventy-two protein spots were detected on the gels, and 9 of the spots were present at different levels in the 4 groups of broilers. These 9 protein spots were selected for identification by mass spectrometry. Two of the spots were found to contain single mitochondrial matrix proteins. Both mitochondrial matrix proteins, the dihydrolipoamide succinyltransferase component of the 2-oxoglutarate dehydrogenase complex and the alpha-subunit of mitochondrial trifunctional enzyme, were present at higher levels in ascites-resistant line broilers with ascites in the present study. The elevated levels of 2 key proteins in aerobic metabolism in ascites-resistant line broilers with ascites observed in the present study suggests that the mitochondria of broilers with this disease may respond inappropriately to hypoxia.

    Background Intractable ascites is one of the causes of graft loss after adult-to-adult living donor liver transplantation (LDLT) using a small graft. Identification of factors associated with increasing posttransplant ascites has important implications for prevention and treatment. Methods All 59 consecutive adult patients who underwent left lobe LDLT without portal inflow modulation between October 2002 and February 2016 were prospectively enrolled. Factors associated with the average daily amount of ascites for 2 weeks after LDLT were assessed. Results The median daily amount of ascites during the 2 weeks was 1052 mL (range, 52-3480 mL). Although 16 of the 59 patients developed intractable ascites, exceeding 1500 mL daily (massive ascites group), the remaining 43 patients produced less than 1500 mL of ascites daily (nonmassive ascites group). The presence of pretransplant ascites (P = 0.001), albumin (P = 0.011), albumin/globulin ratio (P = 0.026), cold ischemia time (P = 0.004), operation time (P = 0.022), and pretransplant portal vein pressure (PVP) (P = 0.047) differed significantly between the 2 groups. Neither posttransplant PVP nor portal vein flow differed between the 2 groups. The variables associated with intractable ascites that remained significant after logistic regression analysis were pretransplant PVP (P = 0.047) and cold ischemia time (P = 0.049). After appropriate fluid resuscitation for intractable ascites, 58 (98%) of the 59 recipients were discharged from hospital after removal of the indwelling drains. Conclusions It is important to shorten the scold ischemia time to reduce massive ascites after LDLT. Pretransplant portal hypertension is more closely associated with ascites production than posttransplant hemodynamic status. PMID:28361122

    The objective of the present study was to use bivariate mixture models to study the relationships between body weight (BW) and ascites indicator traits. Existing data were used from an experiment in which birds were housed in 2 groups under different climate conditions. In the first group, BW, the ratio of right ventricular weight to total ventricular weight (RV:TV), and hematocrit value (HCT) were measured in 4,202 broilers under cold conditions; in the second group, the same traits were measured in 795 birds under normal temperature conditions. Cold-stress conditions were applied to identify individuals that were susceptible to ascites. The RV:TV and HCT were approximately normally distributed under normal temperature conditions, whereas the distributions of these traits were skewed under cold temperature conditions, suggesting different underlying distributions. Fitting a bivariate mixture model to the observations showed that there was only one homogeneous population for ascites traits under normal temperature conditions, whereas there was a mixture of (2) distributions under cold conditions. One distribution contained nonascitic birds and the other distribution contained ascitic birds. In the distribution of nonascitic birds, the inferred phenotypic correlations (phenotypic correlations with 2 distinguishing underlying distributions) of BW with RV:TV and HCT were close to zero (0.10 and -0.07, respectively), whereas in the distribution of ascitic birds, the inferred phenotypic correlations of BW with RV:TV and HCT were negative (-0.39 and -0.4, respectively). The negative inferred correlations of BW with RV:TV and HCT in the distribution of ascitic birds resulted in negative overall correlations (correlations without 2 distinguishing distributions) of BW with RV:TV (-0.30) and HCT (-0.37) under cold conditions. The present results indicate that the overall correlations between BW and ascites traits are dependent on the relative frequency of ascitic and

The diaphragmatic peritoneum of patients with ascites was markedly thickened with infiltration of inflammatory cells and collagen bundles resembling the interstitial changes of peripheral lymphedema. Obliteration of diaphragmatic lymphatic stomata with restricted lymph flow as well as excess lymph formation from portal hypertension are both major factors in the magnitude and intractability of ascites associated with schistosomal hepatic fibrosis.

    Background Malignant ascites is a pathological condition caused by intra- or extra-abdominal disseminated cancer. The object of treatment is palliation. In search of an effective and minimally invasive palliative treatment of malignant ascites placement of a permanent intra peritoneal catheter has been suggested. Purpose To evaluate our experiences with treatment of malignant ascites by implantation of a permanent PleurX catheter. Material and Methods A retrospective study was conducted, comprising 20 consecutive patients with terminal cancer, who had a permanent PleurX catheter implanted because of malignant ascites in the period from February to November 2014. Using the patients’ medical records, we retrieved data on patients and procedures. Results The technical success rate was 100%. Catheter patency was 95.2%, one catheter was removed due to dislocation. Ten patients (50.0%) experienced minor adverse events. No procedural difficulties were reported and there was no need for additional treatment of malignant ascites after catheter implantation. Median residual survival after catheter implantation was 27 days. Conclusion Implantation of a permanent PleurX catheter is a minimally invasive and effective procedure with only minor adverse events and a high rate of catheter patency in patients with malignant ascites caused by terminal cancer disease.

    We investigated the therapeutic role of the herbal combination Euphorbia kansui (GS) and Glycyrrhiza (GC) in ascites during hepatocellular carcinoma (HCC). The AVPR2 and AQP2 expression in kidney tissues of ascites mice in different groups was determined by immunohistochemistry, Western blot, and real-time PCR analyses. When the dose of GS was less than 0.70 g/kg at a ratio of GC : GS not exceeding 0.4 : 1, the combination of GS and GC exhibited synergistic effects on HCC ascites and significantly elevated the expression levels of AVPR2 and AQP2 (all P < 0.05). On the contrary, when GS ≥ 0.93 g/kg and GC ≥ 1.03 g/kg with the GC-to-GS ratio exceeding 1.11 : 1, the combination of GS and GC displayed antagonistic effects on HCC ascites and dramatically reduced the expression levels of AVPR2 and AQP2 (all P < 0.05). Furthermore, the administration of herbal pair GS and GC at different ratios did not exacerbate the pathological changes in liver and kidney tissues of HCC ascites mice. The different combinations of GS and GC exerted synergistic or antagonistic effects on HCC ascites, partially by regulating the expression of AVPR2 and AQP2. PMID:27247609

    The purpose of this retrospective review of the charts of 6 children who underwent surgical treatment of chylous ascites refractory to conservative measures between 1993 and 2006 was to evaluate the efficiency of fibrin glue application for control of lymph leakage. Five children had postoperative chylous ascites (neuroblastoma, 4; cystic lymphangioma, 1) and 1 had a congenital malformation. Surgical exploration revealed large areas of diffuse lymphatic leakage in all of the patients. Lymphatic fistula was not identified intraoperatively in any patient. Ingestion of lipophilic dye in a concentrated fatty meal was not helpful in locating a lymph fistula. Absorbable mesh was used in association with glue application in the last 3 patients treated. Control of ascites was achieved immediately in 2 patients and within 3 weeks in 2 patients. Repeat surgery was required in the remaining 2 patients. The mean follow-up time was 4.3 years. One patient died of tumor recurrence 12 months after surgical treatment without relapse of the ascites. Two mild late recurrences were observed at 6 and 11 months after surgery and were managed conservatively. The findings of this study show that fibrin glue application on absorbable mesh after dissection of the leakage zones is easy, safe, and effective. We recommend that surgery with glue application be repeated until control of ascites is achieved. We suggest fibrin glue application as a preventive measure against postoperative chylous ascites.

    Ehrlich ascites-tumour cells accumulate Ca2+ when incubated aerobically with succinate, phosphate and rotenone, as revealed by isotopic and atomic-absorption measurements. Ca2+ does not stimulate oxygen consumption by carefully prepared Ehrlich cells, but des so when the cells are placed in a hypo-osmotic medium. Neither glutamate nor malate support Ca2+ uptake in 'intact' Ehrlich cells, nor does the endogenous NAD-linked respiration. Ca2+ uptake is completely dependent on mitochondrial energy-coupling mechansims. It was an unexpected finding that maximal Ca2+ uptake supported by succinate requires rotenone, which blocks oxidation of enogenous NAD-linked substrates. Phosphate functions as co-anion for entry of Ca2+. Ca2+ uptake is also supported by extra-cellular ATP; no other nucleoside 5'-di- or tri-phosphate was active. The accumulation of Ca2+ apparently takes place in the mitochondria, since oligomycin and atractyloside inhibit ATP-supported Ca2+ uptake. Glycolysis does not support Ca2+ uptake. Neither free mitochondria released from disrupted cells nor permeability-damaged cells capable of absorbing Trypan Blue were responsible for any large fraction of the total observed energy-coupled Ca2+ uptake. The observations reported also indicate that electron flow through energy-conserving site 1 promotes Ca2+ release from Ehrlich cells and that extra-cellular ATP increase permeability of the cell membrane, allowing both ATP and Ca2+ to enter the cells more readily.

    DNA from Ehrlich ascites tumor cells is nicked or gapped by a reaction which is induced by proteases such as autodigested pronase, proteinase K, trypsin, chymotrypsin and subtilisin. The cleavage of the protease-sensitive sites is inhibited by protease inhibitors. The nicks or gaps induced by proteases can be demonstrated by nuclease S1 sensitivity of native DNA and by a change of the sedimentation rate of alkali-denatured DNA. The limit size of denatured DNA released after optimal protease treatment is 8.5 x 10(6) daltons (27 kilo bases). The molecular weight of the native DNA pieces released after nuclease S1 degradation of DNA containing the protease-induced nicks or gaps is in the same order indicating that the protease-sensitive sites are alternatively arranged on the opposite DNA strands at an average distance of 13.5 kilo base pairs. Since the protease-induced nicks or gaps in phosphatase-treated DNA are not attacked by Escherichia coli polymerase I, one or both ends liberated by the protease treatment must be blocked by a material other than phosphate groups. The results are most compatible with peptide/protein linkers joining adjacent single-strand DNA subunits. Alternative explanations such as alkali-stable RNA linkers, protein-protected RNA linkers, site-specific nuclease contaminations in the protease preparations or cellular nucleases activated by the protease treatment are eliminated by the results presented in this paper.

    (1) Ascites syndrome is a growth-related disorder of broilers that occurs more often in fast-growing birds and at low temperatures. The objective of this study was to estimate genetic and phenotypic correlations among ascites-related traits measured either under cold or under normal temperature conditions, and to estimate genetic correlations between ascites-related traits measured under cold and normal conditions. (2) Several traits related to ascites were measured on more than 4000 chickens under cold conditions and on more than 700 chickens under normal conditions. (3) The heritability estimates for body weight (BW) measured under cold and normal conditions were 0.42 and 0.50, respectively, for haematocrit value 0.46 and 0.17, respectively, and for ratio of right to total ventricular weight 0.45 and 0.12, respectively. (4) The genetic correlation between BW and haematocrit value under cold conditions was -0.23 and between BW and ratio of right to total ventricular weight -0.27. Under normal conditions, however, these genetic correlations were 0.55 and 0.50, respectively. (5) These results demonstrate that the heritability estimates of ascites-related traits as well as genetic correlations between ascites-related traits and BW depend on the temperature conditions under which animals are kept. (6) Strong positive genetic correlations (around 0.8) were observed between total mortality, fluid in the abdomen and ratio of right to total ventricular weight under cold conditions. The genetic correlation between ratio of right to total ventricular weight under cold and normal conditions was 0.91. (7) These results suggest that the ratio of right to total ventricular weight measured under normal temperature conditions might serve as a good indicator trait for ascites.

    Modern broilers have been genetically selected for an increased growth rate and improved feed conversion, but they are also more susceptible to ascites. Ascites occurs when there is an imbalance between available oxygen and the oxygen demand of the broiler. We hypothesized that promoting neonatal gut development with a prebiotic, such as Aspergillus meal (Prebiotic-AM), would enhance gut efficiency, decrease the oxygen demand of the gut, and reduce ascites incidence. In this study, we compared the effect of Prebiotic-AM on ascites incidence and gut development in commercial broilers reared at a local altitude (390 m above sea level) and a simulated high altitude (2,900 m above sea level). Half of the birds received a National Research Council recommended corn-soybean ration, and the other half received the same ration supplemented with 0.2% Prebiotic-AM. These 2 groups were further divided into a local altitude group and a simulated high altitude group for a total of 4 treatment combinations. Tissues were collected on d 1, 3, 7, 14, and 21 from the duodenum and lower ileum and placed in 10% buffered formalin for morphometric analysis. At a simulated high altitude, ascites incidence was 68% for birds fed the Prebiotic-AM supplement compared with 92% ascites incidence in birds given the control feed. The simulated high altitude decreased (P < 0.05) gut development, but prebiotic-treated birds reared in hypoxic conditions had similar gut development to control birds reared at local altitude. These data suggest that a feed ration supplemented with Prebiotic-AM may reduce the effect of hypoxia on broiler gut development and ascites incidence.

    Upon hemolysis extracellular hemoglobin causes oxidative stress and cytotoxicity due to its peroxidase activity. Extracellular hemoglobin may release free hemin, which increases vascular permeability, leukocyte recruitment, and adhesion molecule expression. Pancreatitis-associated ascitic fluid is reddish and may contain extracellular hemoglobin. Our aim has been to determine the role of extracellular hemoglobin in the local and systemic inflammatory response during severe acute pancreatitis in rats. To this end we studied taurocholate-induced necrotizing pancreatitis in rats. First, extracellular hemoglobin in ascites and plasma was quantified and the hemolytic action of ascitic fluid was tested. Second, we assessed whether peritoneal lavage prevented the increase in extracellular hemoglobin in plasma during pancreatitis. Third, hemoglobin was purified from rat erythrocytes and administered intraperitoneally to assess the local and systemic effects of ascitic-associated extracellular hemoglobin during acute pancreatitis. Extracellular hemoglobin and hemin levels markedly increased in ascitic fluid and plasma during necrotizing pancreatitis. Peroxidase activity was very high in ascites. The peritoneal lavage abrogated the increase in extracellular hemoglobin in plasma. The administration of extracellular hemoglobin enhanced ascites; dramatically increased abdominal fat necrosis; upregulated tumor necrosis factor-α, interleukin-1β, and interleukin-6 gene expression; and decreased expression of interleukin-10 in abdominal adipose tissue during pancreatitis. Extracellular hemoglobin enhanced the gene expression and protein levels of vascular endothelial growth factor (VEGF) and other hypoxia-inducible factor-related genes in the lung. Extracellular hemoglobin also increased myeloperoxidase activity in the lung. In conclusion, extracellular hemoglobin contributes to the inflammatory response in severe acute pancreatitis through abdominal fat necrosis and inflammation

    Systemic lupus erythematous (SLE) is an auto-immune disease with multiple organ involvements that occurs mainly in young women. Literature data suggest that serositis is more frequent in late-onset SLE. However, peritoneal serositis with massive ascites is an extremely rare manifestation. We report a case of old-onset lupus peritonitis treated successfully by Hydroxychloroquine. A 77-year-old Tunisian woman was hospitalized because of massive painful ascites. Her family history did not include any autoimmune disease. She was explored 4 years prior to admission for exudative pleuritis of the right lung without any established diagnosis. Physical examination showed only massive ascites. Laboratory investigations showed leucopenia: 3100/mm3, lymphopenia: 840/mm3 and trace protein (0.03 g/24 h). Ascitic fluid contained 170 cells mm(3) (67% lymphocytes), 46 g/L protein, but no malignant cells. The main etiologies of exudative ascites were excluded. She had markedly elevated anti-nuclear antibody (ANA) titer of 1/1600 and a significantly elevated titer of antibody to double-stranded DNA (83 IU/mL) with hypo-complementemia (C3 levl was at 67 mg/dL). Antibody against the Smith antigen was also positive. Relying on these findings, the patient was diagnosed with SLE and treated with Hydroxychloroquine 200 mg daily in combination with diuretics. One month later, there was no detectable ascitic fluid and no pleural effusions. Five months later she remained free from symptoms while continuing to take chloroquine. This case was characterized by old age of onset of SLE, the extremely rare initial presentation with lupus peritonitis and massive painful ascites with dramatic response to only hydroxychloroquine treatment.

    Genetic selection for an ascites-resistant line of broilers is seen as a permanent solution to the ascites problem. Ascites-resistant and ascites-susceptible lines have been developed using sire family selection based on mortality data taken from siblings reared in a hypobaric chamber (simulated 2,900 m above sea level). The relaxed line is representative of the original commercial pureline stock randomly mated with no artificial selection pressure. The objectives of this study were to evaluate the differences between the lines when reared in floor pens and subjected to an ascites-inducing cold stress. Seven hundred eighty three straight run broilers were reared in floor pens at local elevation (390 m above sea level). Feed and water were available ad libitum. Birds were brooded at 32 C during the first week. The second week birds were maintained at 30 degrees C. Cold stress was applied for the remaining 4 wk at 14 degrees C. Mortalities were necropsied daily to determine cause of death. Birds and feed were weighed weekly. At 6 wk, five birds per pen were bled, and half the survivors in each pen (8 to 15 birds) were killed, necropsied, and scored for ascites. Blood gases, clinical chemistries, and blood cell counts were taken. Liver, spleen, split heart, and lung weights were recorded. Body weights were not different among the resistant, susceptible, and relaxed lines (P < 0.05). Feed conversion was better in the resistant line when compared to the susceptible and relaxed lines (P < 0.05). Ascites incidence, as measured by mortality and lesion score at necropsy, was higher in the susceptible and relaxed lines when compared to the resistant line; 18.8, 12.7, and 1.6% respectively (P < 0.001). Susceptible and relaxed lines showed more right ventricular hypertrophy when compared with the resistant line (P < 0.05). The results show that under severe cold stress at local altitude (390 m above sea level), the ascites-resistant line was growing as rapidly as the other

    Within-line opportunities for selection against ascites were studied in a data set comprising a 10-line comparison. The study attempted to reveal whether contrasts between lines provide reliable candidate traits for within-line selection. Mortality was chosen as the reference trait. As no pedigree information was available, a trait was required that related mortality to the nonmortality data. By principal component analysis, such a trait (ASC_INDIC = ascites indicator) was developed from pathology data. The composite trait ASC_INDIC ranked lines well for their mortality figures (r = 0.96), from which it was concluded that ASC_INDIC represents an underlying continuous ascites trait. Between lines, blood gas traits seemed to be the most promising traits. Within lines, performance traits appeared to be highly correlated to ascites. Comparison of within-line variation to between-line contrasts revealed considerable differences. The high correlation of the blood gas traits with mortality was not present within lines. However, although the magnitude was considerably reduced, the nature of the blood gas traits in their relationship to ascites was similar within and between lines. The study primarily demonstrates that contrasts between lines carry systematic but limited information for within-line coherence. Therefore, line contrasts must be interpreted with care when aiming to study genetic variation and coherence within lines.

  14. The transjugular intrahepatic portosystemic shunt for the management of cirrhotic refractory ascites.

    PubMed

    2006-07-01

    Cirrhotic ascites results from sinusoidal hypertension and sodium retention, which is secondary to a decreased effective arterial blood volume. Transjugular intrahepatic portosystemic shunt (TIPS) placement is currently indicated in cirrhotic patients with refractory ascites who require large-volume paracentesis (LVP) more than two or three times per month. TIPS placement is associated with normalization of sinusoidal pressure and a significant improvement in urinary sodium excretion that correlates with suppression of plasma renin activity, which is, itself, indicative of an improvement in effective arterial blood volume. Compared with serial LVP, placement of an uncovered TIPS stent is more effective at preventing ascites from recurring; however, increased incidence of hepatic encephalopathy and shunt dysfunction rates after TIPS placement are important issues that increase its cost. Although evidence suggests that TIPS placement might result in better patient survival, this needs to be confirmed, particularly in light of the development of polytetrafluoroethylene-covered stents. Favorable results apply to centers experienced in placing the TIPS, with the aim being to decrease the portosystemic gradient to <12 mmHg but >5 mmHg. This article reviews the pathophysiologic basis for the use of a TIPS in patients with refractory ascites, the results of controlled trials comparing TIPS placement (using uncovered stents) versus LVP, and a systematic review of predictors of death after TIPS placement for refractory ascites.

    POEMS syndrome is a multisystem disorder characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes. POEMS syndrome is a rare cause of refractory ascites. We report the case of a patient with POEMS syndrome presenting with massive ascites who was treated with very-low-dose lenalidomide and dexamethasone. A 57-year-old Japanese man was admitted to our hospital with pleural effusion, massive ascites, and leg edema. The diagnosis of POEMS syndrome was made based on the combination of the following findings: peripheral neuropathy, organomegaly, endocrinopathy, serum monoclonal protein elevation, skin changes, plasma VEGF elevation, and evidence of extravascular volume overload. Renal dysfunction induced by biopsy-proven renal involvement of POEMS syndrome was observed. Massive ascites of the patient dramatically diminished with long-time treatment of very-low-dose lenalidomide and dexamethasone. Lenalidomide seems to be a very promising therapy for POEMS syndrome presenting with extravascular volume overload such as edema, pleural effusion, and ascites. Very-low-dose lenalidomide might be effective especially for the patients with POEMS-related nephropathy. PMID:24782932

    Carbohydrate antigen 125 (CA125) is a tumor-marker frequently associated with ovarian malignancies; however, benign gynecologic conditions (e.g. ovarian cysts) commonly cause a smaller increase in CA125 levels. This report describes an elderly Japanese woman with high CA125 levels and massive ascites caused by hypothyroidism. A 67-year-old woman presented herself with a weight gain of about 12 kg and abdominal distension. Her serum CA125 level was markedly elevated (822 U/ml) and abdominal CT revealed a right ovarian cyst and massive ascites. Hormonal laboratory data showed severe primary hypothyroidism with a serum TSH of 594 IU/L and a free thyroxin level of 0.05 ng/dl. Ascitic fluid was found to be exudate with a high protein content of 42 g/L. Cytological analysis and FDG-PET showed no evidence of malignancy. The ascites completely disappeared and serum CA125 normalized after adequate hormonal replacement therapy. These data suggest that hypothyroidism should be considered in patients with ascites and elevated serum CA125.

    Pulmonary hypertension syndrome (PHS), or ascites, is characterized by elevated pulmonary arterial pressure and pulmonary vascular resistance accompanied by right ventricular hypertrophy (RVH) and fluid accumulation in the abdominal cavity. Experimental models are required for triggering PHS to study the pathogenesis of this syndrome and to select resistant genetic lines. Caffeine increases vascular resistance and promotes systemic hypertension in mammals, but a similar effect of caffeine on the pulmonary circulation had not previously been demonstrated. Two experiments were conducted to evaluate the impact of caffeine alone (Exp. 1) or in combination with cold temperature (Exp. 2) on parameters associated with PHS in young broiler chicks. In Exp. 1, 288 chicks were distributed among 24 pens and brooded at standard environmental temperatures, and on d 3 through 42 caffeine was added to the water at doses of 0 (control), 6.25, 12.5, 25, 50, and 100 mg/(kg BW·d). In Exp. 2, 192 chicks were distributed among 16 pens and brooded at cool environmental temperatures, and on d 3 through 42 caffeine was added to the water at doses of 0 (control), 15, 30, and 45 mg/(kg BW·d). In Exp. 1 caffeine administered at or above 12.5 mg/(kg BW·d) induced severe PHS and resulted in acute mortality and RVH ( < 0.05). Hematocrit also slightly increased by caffeine supplementation ( = 0.07). In Exp. 2 caffeine-treated broilers exposed to cold temperatures remarkably exhibited PHS incidences and developed RVH with right ventricular to total ventricular weight ratios of 30% or greater. Moreover, hematocrit significantly increased because of caffeine supplementation in cool ambient temperature ( = 0.002). Our data demonstrate that caffeine induces high incidences of PHS in broilers, which is exacerbated by exposure to low temperatures.

    Next to water, tea is the most ancient and widely consumed beverage in the world. Epidemiological studies have suggested a cancer protective effect, but the results obtained so far are not conclusive. In the current study, mechanisms of the apoptogenic effect of black tea extract were delineated. Black tea administration to Ehrlich's ascites carcinoma (EAC)-bearing Swiss albino mice caused a significant decrease in the tumor cell count in a dose-dependent manner. Flowcytometric analysis showed an increase in the number of cells in the sub-G(0)/G(1) population signifying tumor cell apoptosis by black tea. These results were further confirmed by nuclear staining that demonstrated distinct morphological features of apoptosis. Our data also revealed an increase in the expression of pro-apoptotic protein p53 in EAC. It is known that upon p53 induction, multiple downstream factors contribute to the decision making between growth arrest and apoptosis. Among those, pro-apoptotic gene Bax is up regulated during p53-mediated apoptosis. On the other hand, p53-mediated growth arrest involves p21 as a major effecter. In our system, increase in p53 expression was followed by moderate expression of p21/Waf-1 and high expression of Bax at protein levels. Interestingly, anti-apoptotic protein Bcl-2 was down regulated resulting in decrease in Bcl-2/Bax ratio. All these observations together signify that black tea-induced apoptogenic signals overrode the growth-arresting message of p21, thereby leading the tumor cells towards death.

    The objective of this study was to evaluate the gluconeogenic response of in vitro stimulated hepatocytes from control broilers and broilers with clinical manifestations of the ascites syndrome. The basal rate of glucose synthesis from lactate was found to be threefold greater in sick birds than in the control group and stimulation obtained with epinephrine was found to be quantitatively similar in both groups. Under basal conditions, the hepatocytes from the sick broilers exhibited 60% more ammonium than the control birds. In addition, the quantification of thiobarbituric acid reactive substances, as indicators of cellular lipoperoxidation, showed an increase of over 100% in heart and liver of sick broilers fowl. In conclusion, the complex integrated response of gluconeogenesis to epinephrine is maintained in broilers with ascites, although their hepatocytes present changes compatible with those observed in cases of oxidative stress. It is not known whether this stress is a cause or a consequence of the ascites syndrome.

    Arterioportal fistulas (APFs) are a group of vascular disorders, in which systemic arteries communicate with the portal circulation, presenting as a congenital syndrome or more commonly acquired from iatrogenic instrumentation or abdominal trauma. We report the case of a 58-year-old man who developed ascites without underlying risk factors for portal hypertension, which was attributed to an APF found on imaging, manifesting 43 years after sustaining a liver laceration. After angiographic embolization of the APF, the patient’s ascites resolved completely. The prolonged latent period between the patient’s abdominal trauma and eventual presentation with ascites highlights the need to consider vascular malformations in the differential diagnosis of unexplained noncirrhotic portal hypertension.

    A six-year-old Rottweiler with chronic ascites and moderate panhypoproteinaemia that had been treated with large volume paracentesis over several months duration was diagnosed with a large bi-atrial mass and hepatic fibrosis. For palliative treatment, a peritoneo-vesical automated fluid shunt system with an integrated chargeable battery and an integrated computer to control pump function and to transmit data transcutaneously was implanted by coeliotomy. The pump was left in place for 10 weeks, eliminating the need for further paracentesis during this time. At the end of this period, no ascites was discernible and serum protein concentrations had returned to their respective reference intervals. As a complication, decubitus with skin perforation had developed above the pump. Besides palliative treatment of chronic refractory ascites, this pump may have application in other conditions characterised by chronic cavity effusion or in peritoneal dialysis.

    Image-guided percutaneous thermal ablation is increasingly utilized in the treatment of hepatic malignancies. Peripherally located hepatic tumors can be difficult to access or located adjacent to critical structures that can be injured. As a result, ablation of peripheral tumors may be avoided or may be performed too cautiously, leading to inadequate ablation coverage. In these cases, separating the tumor from adjacent critical structures can increase the efficacy and safety of procedures. Artificial ascites and artificial pneumoperitoneum are techniques that utilize fluid and gas, respectively, to insulate critical structures from the thermal ablation zone. Induction of artificial ascites and artificial pneumoperitoneum can enable complete ablation of otherwise inaccessible hepatic tumors, improve tumor visualization, minimize unintended thermal injury to surrounding organs, and reduce post-procedural pain. This pictorial essay illustrates and discusses the proper technique and clinical considerations for successful artificial ascites and pneumoperitoneum creation to facilitate safe peripheral hepatic tumor ablation.

    The objective of this report was to evaluate the ascitic fluid of a patient with refractory lupus ascites (proband) at different time points-pre- and post-intraperitoneal treatment with dexamethasone-using a multiparametric approach which included the presence of autoantibodies and pro- and anti-inflammatory cytokines and chemokines, and a proteomic analysis. As controls, we studied two additional patients also with lupus ascites (only at basal evaluation) and two patients with ascites due to alcoholic liver cirrhosis. High levels of anti-dsDNA and anti-nucleosomes autoantibodies were detected in the ascitic fluid of all lupus patients and remained elevated in the proband throughout the follow-up. All lupus patients have detectable ascitic high levels of IL-6, IL-8, IL-10, TNF-α, MCP-1, and IGF-1 which diminished gradually in the proband after intraperitoneal dexamethasone. In the proteomic analysis of the ascitic fluid, a marked increment of apolipoprotein A1 was observed and again, it diminished gradually after intraperitoneal treatment. Our findings further support the use of intraperitoneal steroids as an effective therapeutic option for refractory ascites in systemic lupus erythematosus.

    Purpose: Peritoneal venous shunts (PVSs) are widely used for palliating symptoms of refractory malignant ascites and are recognized as one of the practical methods. However, reliable clinical data are insufficient because most previous reports have been small studies from single centers. We conducted a retrospective, multicenter study to evaluate the safety and efficacy of radiologically placed PVSs in patients with malignant refractory ascites. Methods: A total of 133 patients with malignant ascites refractory to medical therapies were evaluated for patient characteristics, technical success, efficacy, survival times, adverse events, and changes in laboratory data. Results: PVSs were successfully placed in all patients and were effective (i.e., improvement of ascites symptoms lasting 7 days or more) in 110 (82.7%). The median duration of symptom palliation was 26 days and median survival time was 41 days. The most frequent adverse event was PVS dysfunction, which occurred in 60 (45.1%) patients, among whom function was recovered with an additional minimally invasive procedure in 9. Abnormalities in coagulation (subclinical disseminated intravascular coagulation) occurred in 37 (27.8%) patients, although only 7 (5.3%) developed clinical disseminated intravascular coagulation. Other major adverse events were gastrointestinal bleeding (9.8%), sepsis (3.8%), and acute heart failure (3.0%). PVS was least effective in patients with elevated serum creatinine, bloody ascites, or gynecologic tumor. Conclusions: Radiological PVS is a technically feasible and effective method for palliating the symptoms from refractory malignant ascites, but preoperative evaluation and monitoring the postprocedural complications are mandatory to preclude severe adverse events after PVS.

    1974-07-01

    Much of the lipid present in the ascites plasma in which Ehrlich cells grow is contained in very low density lipoproteins (VLDL). Chemical measurements indicated that triglycerides were taken up by the cells during in vitro incubation with ascites VLDL. When tracer amounts of radioactive triolein were incorporated into the ascites VLDL, the percentage uptakes of glyceryl tri[1-(14)C]oleate and triglycerides measured chemically were similar. The cells also took up [2-(3)H]glyceryl trioleate that was added to VLDL, but the percentage of available (3)H recovered in the cell lipids was 30-40% less than that of (1 4)C from glyceryl tri[1-(1 4)C]oleate. This difference was accounted for by water-soluble (3)H that accumulated in the incubation medium, suggesting that extensive hydrolysis accompanied the uptake of VLDL triglycerides. Radioactive fatty acids derived from the VLDL triglycerides were incorporated into cell phospholipids, glycerides, and free fatty acids, and they also were oxidized to CO(2). Triglyceride utilization increased as the VLDL concentration was raised. These results suggest that one function of the ascites plasma VLDL may be to supply fatty acid to the Ehrlich cells and that the availability of fatty acid to this tumor is determined in part by the ascites plasma VLDL concentration. Although Ehrlich cells incorporate almost no free glycerol into triglycerides, considerable amounts of [2-(3)H]glyceryl trioleate radioactivity were recovered in cell triglycerides. This indicates that at least some VLDL triglycerides were taken up intact. The net uptake of VLDL protein and cholesterol was very small relative to the triglyceride uptake, suggesting that intact triglycerides are transferred from the ascites VLDL to the Ehrlich cells and that hydrolysis occurs after the triglyceride is associated with the cells.

    The leaves of Chenopodium ambrosioides L. [Chenopodiaceae] ('mastruz') have been indicated for the treatment of several diseases, among which the cancer. There are no results focusing the effect of C. ambrosioides treatment on tumor development in vivo. The aim of this study was to investigate the effect of treatment with C. ambrosioides on Ehrlich tumor development. Swiss mice were treated by intraperitoneal route (i.p.) with hydroalcoholic extract from leaves of C. ambrosioides (5 mg/kg) or with PBS (control group) 48 h before or 48 h later the Ehrlich tumor implantation. The tumor cells were implanted on the left footpad (solid tumor) or in the peritoneal cavity (ascitic tumor). To determine the solid tumor growth, footpad was measured each 2 days until the fourteenth day, when the feet were weighed. Ascitic tumor development was evaluated after 8 days of tumor implantation by quantification of the ascitic fluid volume and tumor cell number. The i.p. administration of C. ambrosioides extract before or after the tumor implantation significantly inhibited the solid and ascitic Ehrlich tumor forms. This inhibition was observed in ascitic tumor cell number, in the ascitic volume, in the tumor-bearing foot size and foot weight when compared to control mice. The treatments also increased the survival of tumor-bearing mice. In conclusion, C. ambrosioides has a potent anti-tumoral effect which was evident with a small dose and even when the treatment was given two days after the tumor implantation. This effect is probably related with anti-oxidant properties of C. ambrosioides.

    BACKGROUND AND AIMS. In cirrhotic patients with spontaneous bacterial peritonitis (SBP) higher polymorphonuclear (PMN) count in ascitic fluid have been reported in infections caused by Gram-negative bacilli (GNB) as opposed to Gram-positive cocci (GPC). However, the influence of other associated factors on the PMN count, such as the specific microorganism causing the episode of SBP, has not been well established. METHODS. Retrospective observational study of 194 episodes of positive ascitic and/or blood culture SBP in 159 patients with liver cirrhosis (2001-2009). Parameters associated with PMN count in ascitic fluid at diagnosis were evaluated. RESULTS. The multivariate analysis (model 1) showed that a virulent etiology of the infection [coefficient 3.941 (95% confidence interval (95 CI): 0.421-7.461)] and the model for end-stage liver disease (MELD) score [coefficient 0.196 (95 CI: 0.007-0.384)] were positively associated with the PMN count in ascites, while a nosocomial acquisition was inversely associated [coefficient -3.546 (95 CI: -6.855 - -0.238)]. A nonsignificant trend toward higher PMN count was found in GNB versus GPC, but there were differences between groups of microorganisms: pyogenic streptococci [median (p25-p75): 3211 (1615-8004)], Enterobacteriaceae [2958 (917-7690)], Vibrionaceae [9215 (375-17280)], nonfermenting GNB [1384 (565-3865)], viridans group streptococci [1044 (503-2354)] and enterococci [1050 (476-4655)](p = 0.005). No clear cut-offs of ascitic PMN count predicting a particular etiology could be calculated out of these data. CONCLUSIONS. In cirrhotic patients with SBP, the causing microorganism, the place of acquisition of the infection and the host liver condition were the main factors determining PMN count in ascitic fluid. Third-generation cephalosporin resistance was associated with low PMN count probably because this group included bacteria with inherent low virulence.

    A case of spontaneous bacterial peritonitis (SBP) developed in an old man whose ascitic fluid was related neither to portal hypertension nor nephrotic syndrome, but with severe hypoalbuminemia emerged after a massive bleeding from a gastric ulcer in a malnutrition state. Ascitic fluid, increasing day by day, yielded Enterobacter cloacae and Bacteroides fragilis. Though autopsy was not carried out because of refusal of his family, neither liver necropsy, nor abdominal CT scan nor repeated abdominal ultrasonography showed findings suggesting existence of liver cirrhosis. In the presence of his ascites, the extent of a chemiluminescence (CL) response of polymorphonuclear cells from volunteers was significantly lower than that of his serum. This report shows that SBP can develop in a patient with ascites unrelated to portal hypertension when ascitic fluid induces little CL response.

    Ethacrynic acid is a loop diuretic little used today because of its side-effect profile and the availability of multiple alternative agents. However, in our clinical experience, ethacrynic acid can alleviate acute congestive heart failure and ascites resistant to other diuretics. Two patients aged 89 and 94 in life-threatening pulmonary edema were stabilized by ethacrynic acid after furosemide proved ineffective. A third patient, aged 83, with a pleural effusion and ascites secondary to end-stage hepatitis B and C, responded to ethacrynic acid when spironolactone and furosemide produced little urine output. Ethacrynic acid may have a unique niche as a diuretic of last resort, especially in geriatric practice.

    1. Male broilers of two different genetic stocks, a pure broiler sire line (A) and commercially available Ross broilers (B), were used to study the effect of differences in haematocrit values in 12-d-old chickens on the development of ascitic symptoms. Body weight gain (BWG), feed intake (FI) and feed conversion ratio (FRC) were measured from 2 to 5 weeks of age. Mortality was recorded from 2 to 6 weeks. The birds were kept at a low ambient temperature to stimulate the incidence of ascites. 2. From each stock 32 birds with the highest (High Ht) and 32 birds with the lowest (Low Ht) haematocrit values in venous blood were selected at 12 d of age for an examination on susceptibility for the ascites syndrome at 5 weeks. 3. At 2 weeks 448 birds per stock (including High Ht and Low Ht birds) were allotted to 32 floor pens (1 High Ht and 1 Low Ht in each pen). Venous blood samples were taken weekly in High Ht and Low Ht birds for haematocrit measurements and at week 5 also thyroid hormone (T3, T4) concentrations in plasma were measured. At 5 weeks all High Ht and Low Ht birds were examined post-mortem and arterial pressure index, heart weight, lung weight and liver weight (all relative to body weight) were recorded. High values for arterial pressure index, relative heart and liver weights and low values for relative lung weights and plasma thyroid hormone were considered to be indicators for ascites susceptibility. 4. Stock A, with the highest ascites mortality, had lower values for BWG and FCR than stock B. Throughout, a clear difference in Ht values between High Ht and Low Ht birds was maintained. No significant effects of 12-d haematocrit values were found on the incidence of ascitic symptoms until week 5. High Ht values tended to correlate with low relative lung weights and low plasma T3 concentrations in High Ht birds. 5. Within the groups of selected birds, there was an effect of stock on ascitic symptoms (arterial pressure index, relative heart weight and T3

    The use of paracentesis has recently been reproposed as a safe and effective alternative to diuretics for management of ascites. We have investigated the clinical and biochemical effects of large-volume paracentesis in 19 cirrhotics with tense ascites, and the relative changes in the hormones involved in sodium and water renal handling. Plasma renin activity (PRA), aldosterone (PA), and arginine vasopressin (AVP) levels and conventional liver and renal function tests were measured before and after 1, 2, and 7 days after the paracentesis. No complications were observed, but patients regained 37% of the weight lost after 1 wk. Percent weight regained was significantly and directly correlated with PA concentration measured before the paracentesis. No changes were recorded after paracentesis in biochemical and clinical data, except for a significant drop in diastolic blood pressure. No changes in AVP levels were observed. A significant increase in PA occurred after paracentesis, with a maximum peak after 48 h. The increase in PA was not accompanied by changes in PRA, but was associated with a reduction of urinary sodium excretion. A relevant fraction of body aldosterone was confined to the ascitic fluid. We conclude that the clinical results of a large-volume paracentesis can be predicted in part on the basis of PA measurement, and that removal of ascites is followed by an increase of PA of uncertain origin and effectiveness.

    The objective of the present study was to estimate heritabilities for ascites-related traits in broilers and to assess the importance of maternal genetic effects for these traits. Several traits related to ascites were measured on more than 4,000 broilers kept under cold conditions. Heritabilities were estimated using an animal model with a direct genetic effect and a model with direct and maternal genetic effects. Estimated heritabilities from the direct genetic effects model were 0.46 for hematocrit value, 0.42 for BW, 0.47 for right ventricular weight, 0.46 for total ventricular weight, 0.45 for ratio of right ventricular weight to the total ventricular weight, 0.32 for total mortality, and 0.18 for fluid accumulation in the heart sac. Maternal effects significantly influenced the traits BW, total ventricular weight, and total mortality. Direct and maternal heritabilities, respectively, for BW were 0.21 and 0.04, for total ventricular weights were 0.29 and 0.03, and for total mortality were 0.16 and 0.05. The heritability estimates for ascites-related traits and the significance of maternal genetic effects for most of these traits indicate that direct and maternal genetic effects play an important role in the development of the ascites syndrome.

    The effects of graded atmospheric O2 concentration (12, 14, 16, 18, and 20.6%) on chick performance and propensity to develop ascites were investigated using commercial male broilers. Chicks were housed in calorimetry chambers for 2 wk with incoming air diluted with N to provide the desired O2 concentration at thermoneutral (TN) ambient temperature. Day 14 body weight, weight gain, feed consumption, and gain-to-feed ratio increased (P < 0.01) as O2 concentration incrementally rose from 12 to 20.6%. Body weight was 138 g for the lowest atmospheric O2 level compared to 371 g for 20.6% O2. The greatest treatment difference occurred between the 12 and 14% O2 concentrations. Growth depression appeared related to feed consumption. Ascites heart ratio (AHR), ascites score (AS), right ventricular mass (RVM), and hematocrit (HCT) all increased (P < 0.01) as O2 concentration decreased. Blood HCT appeared to be a more sensitive indicator of physiological change attributable to atmospheric O2 than AHR, AS, or RVM. The data reported herein suggests that 19.6% atmospheric O2 is the minimal allowable level for housing birds within a relatively stress-free, TN environment to avoid cardiac and HCT changes related to ascites.

    Malignant ascites indicates the presence of malignant cells in the peritoneal cavity and is a grave prognostic sign. While survival in this patient population is poor, averaging about 20 wk from time of diagnosis, quality of life can be improved through palliative procedures. Selecting the appropriate treatment modality remains a careful process, which should take into account potential risks and benefits and the life expectancy of the patient. Traditional therapies, including paracentesis, peritoneovenous shunt placement and diuretics, are successful and effective in varying degrees. After careful review of the patient’s primary tumor origin, tumor biology, tumor stage, patient performance status and comorbidities, surgical debulking and intraperitoneal chemotherapy should be considered if the benefit of therapy outweighs the risk of operation because survival curves can be extended and palliation of symptomatic malignant ascites can be achieved in select patients. In patients with peritoneal carcinomatosis who do not qualify for surgical cytoreduction but suffer from the effects of malignant ascites, intraperitoneal chemotherapy can be safely and effectively administered via laparoscopic techniques. Short operative times, short hospital stays, low complication rates and ultimately symptomatic relief are the advantages of laparoscopically administering heated intraperitoneal chemotherapy, making it not only a valuable treatment modality but also the most successful treatment modality for achieving palliative cure of malignant ascites.

    A Probabilistic Neural Network (PNN) was trained to predict ascites in broilers based on minimally invasive inputs (i.e., physiological factors that do not require the death of the bird). A PNN is a supervised, three-layer, artificial neural network that classifies input patterns (e.g., physiological data) into specific output categories (e.g., ascites or no ascites). The PNN inputs were O2 level in the blood, body weight, electrocardiogram (ECG), hematocrit, S wave, and heart rate of individual birds. These data were from three experiments that have been described previously (Roush et al., 1996a,b). The three data sets were pooled into a combined data set for a total of 170 observations. From the pooled data, a training set (117 birds), a calibration set (17 birds), and a verification set (36 birds) were extracted. The PNN was trained on the training data set. To prevent the PNN from overfitting the training data, the neural network was evaluated on its ability to make correct predictions of the calibration data set. At the point at which the neural network made the highest number of correct classifications for the calibration data set, the trained neural network was saved on the computer. When the PNN was applied to the complete data set, the sensitivity or proportion of the birds with ascites that the PNN correctly diagnosed was 0.97 (75/77 birds). The specificity or proportion of birds that the PNN made a correct diagnosis of not having ascites was 0.98 (91/93 birds). When the PNN was applied to the verification data set, which was not subjected to neural network training, the sensitivity was 0.95 (19/20) and the specificity was 0.88 (14/16 birds). Use of models developed with artificial neural networks may enhance the diagnosis of ascites in broilers. The results may be useful in choosing and developing broiler strains that do not have a propensity for ascites.

    It has been demonstrated that the incidence of ascites can be significantly reduced through feed restriction. This method is thought to have an effect by slowing the growth rate of the birds. Interestingly, when birds are grown in a hypobaric chamber, ascites incidence increases while the overall growth rate of the birds is decreased. Unfortunately, the restriction programs practiced also have a detrimental effect on growth characteristics. An experiment was conducted to determine if the timing and duration of feed restriction can be used to reduce the incidence of ascites for broilers reared under high altitude and local elevation without having a negative impact on growth. A total of 600 commercial broiler males were used. Birds were divided, placing 360 birds in the hypobaric chamber at a simulated 2900 m (9,500 ft) above sea level, and 240 birds were placed at local elevation [390 m (1,300 ft) above sea level]. At each altitude there were four treatments: 1) fully fed controls; 2) feed available for 8 h/d for 6 wk (the duration of the study); 3) feed available for 8 h/d during the first 3 wk, then full feed for the remaining 3 wk; and 4) full feed for the first wk, then 3 wk of 8 h of feed availability, then 2 wk of full feed. Birds and feed were weighed weekly, and mortalities were necropsied to determine the cause of death. At the end of 6 wk, blood samples were taken, and the birds were weighed, necropsied, and scored for ascites, and organ weights were recorded. All feed restriction treatments significantly reduced ascites incidence, when compared with the fully fed controls. Treatment 2 birds were significantly lighter than any other group at both altitudes. The fully fed controls at local elevation were heavier than the fully fed controls at simulated high altitude, as seen in past experiments.

    AIM: To investigate the role of tolvaptan in regulating aquaporin (AQP)-2 expression and fecal water content in cirrhotic rats with ascites. METHODS: Cirrhosis with ascites was induced in rats by repetitive dorsal injection of CCl4 for 14 wk. In total, 84 cirrhotic rats with ascites divided into three groups (vehicle, 3 mg/kg and 5 mg/kg tolvaptan), and then further divided into five subgroups (days 1, 2, 3, 4, and 5). Blood samples were obtained to measure vasopressin and sodium concentrations. Rats were killed and colonic mucosa was scraped for analysis of protein expression and AQP-2 transcriptional level. The whole layer was fixed for hematoxylin&eosin (HE) staining and feces were collected for determination of fecal water content. CONCLUSION: Compared with vehicle, vasopressin decreased significantly in the tolvaptan groups from day 2 to a similar level in each treatment group. AQP-2 showed significant upregulation in cirrhotic rats with ascites compared with an untreated control group (100% ± 22.9% vs 22.2% ± 10.23%, P < 0.01). After administration of tolvaptan, AQP-2 expression began to decrease significantly from day 2 in each treatment group, but no significant difference was finally found between the treatment groups. Fecal water content in the distal colon was increased by 5 mg/kg tolvaptan on day 1 (66.8% ± 9.3% vs 41.4% ± 6.3%, in the vehicle group, P < 0.05). Fecal water content returned to baseline at day 4 at the latest in both treatment groups, and did not correspond to the change in AQP-2 expression. HE staining of the colonic mucosa showed no mucosal damage related to tolvaptan. CONCLUSION: Upregulation of AQP-2 in the distal colon is found in cirrhotic rats with ascites. Tolvaptan inhibits its expression and may decrease water reabsorption and induce diarrhea. PMID:27022218

    Background In human cirrhosis, adrenergic hyperfunction causes proximal tubular fluid retention and contributes to diuretic-resistant ascites, and clonidine, a sympatholytic drug, improves natriuresis in difficult-to-treat ascites. Aim To compare clonidine (aspecific α2-adrenoceptor agonist) to SSP-002021R (prodrug of guanfacine, specific α2A-receptor agonist), both associated with diuretics, in experimental cirrhotic ascites. Methods and Results Six groups of 12 rats were studied: controls (G1); controls receiving furosemide and potassium canrenoate (G2); rats with ascitic cirrhosis due to 14-week CCl4 treatment (G3); cirrhotic rats treated (over the 11th-14th CCl4 weeks) with furosemide and canrenoate (G4), furosemide, canrenoate and clonidine (G5), or diuretics and SSP002021R (G6). Three rats of each group had their hormonal status and renal function assessed at the end of 11th, 12th, 13th, and 14th weeks of respective treatments.Cirrhotic rats in G3 and G4 gained weight over the 12th-14th CCl4 weeks. In G4, brief increase in sodium excretion over the 11th-12th weeks preceded worsening of inulin clearance and natriuresis (diuretic resistance). In comparison with G4, the addition of clonidine (G5) or guanfacine (G6) to diuretics improved, respectively, sodium excretion over the 11th-12th CCl4 weeks, or GFR and electrolytes excretion over the 13th-14th CCl4 weeks. Natriuretic responses in G5 and G6 were accompanied by reduced catecholamine serum levels. Conclusions α2A-receptor agonists restore glomerular filtration rate and natriuresis, and delay diuretic-resistant ascites in experimental advanced cirrhosis. Clonidine ameliorates diuretic-dependent natriuresis just for a short time. PMID:27384184

    The study objective was to compare the effect of different angles of lying positions on the physiological indices of patients with cirrhosis ascites. Chronic liver disease and cirrhosis were ranked 9th among the top 10 causes of death. Ascites is the most common cirrhosis comorbidity. Body posture can affect pulmonary ventilation and arterial oxygen partial pressure, making it an important clinical nursing intervention significantly affecting patient recovery. This was a quasi-experimental study design. From a medical center in Taiwan, 252 patients with cirrhosis ascites were recruited. Subjects were randomly divided into three groups by bed angle: 15°, 30°, and 45°. Physiological indices were measured at 5, 10, 15, 20, 25, and 30 minutes to determine any changes in heart rate, respiration rate, and oxygenation saturation. Data analysis included descriptive statistics and the generalized estimating equation for statistical analysis with significance set at α= 0.05. After controlling for confounding variables, the three groups differed significantly in heart rate at 20, 25, and 30 minutes, oxygenation saturations at 15 and 20 minutes, and respiration rate at 5 and 10 minutes (α< 0.05). Body posture can affect pulmonary ventilation and arterial oxygen partial pressure and is thus an important clinical nursing intervention that significantly affects the recovery of patients. When caring for patients with cirrhosis ascites, nurses should help patients to choose the most comfortable angle for them with no particular restrictions. Our results can be used to guide nurses in making a plan for health education and nursing that improves the quality of care for patients with chronic liver disease and cirrhosis patients with ascites.

    The pocket ultrasound device (PUD) is a new tool that may be of use in the early detection of ascites. Abdominal ultrasound-guided paracentesis has been reported to decrease the rate of complications due to the procedure, but must be performed in a healthcare setting; this new tool may be a useful on an ambulatory basis. The aim of this study was to determine the diagnostic usefulness of the PUD in the diagnosis of ascites and the safety of guided paracentesis. We conducted a retrospective study that included adult patients suspected of having ascites and in whom an evaluation was performed with the PUD to identify it. Concordance with abdominal ultrasound (AUS) was determined with the Kappa coefficient. Sensitivity (Se), specificity (Sp) and likelihood ratios (LR) were determined and compared with physical examination, AUS, computed tomography and procurement of fluid by paracentesis. Complications resulting from the guided paracentesis were analyzed. 89 participants were included and 40 underwent a paracentesis. The PUD for ascites detection had 95.8 % Se, 81.8 % Sp, 5.27 +LR and 0.05 -LR. It had a concordance with AUS of 0.781 (p < 0.001). Technical problems during the guided paracentesis were present in only two participants (5 %) and three patients (7.5 %) developed minor complications that required no further intervention. There were no severe complications or deaths. This study suggests that the PUD is a reliable tool for ascites detection as a complement to physical examination and appears to be a safe method to perform guided paracentesis.

    Broilers from three consecutive hatches were exposed to cool temperatures to amplify the incidence of pulmonary hypertension syndrome (PHS, ascites). The largest apparently healthy individuals on Day 42 were evaluated using minimally invasive diagnostic indices [percentage saturation of hemoglobin with oxygen, hematocrit (HCT), heart rate, electrocardiogram (ECG) Lead II, body weight), then they were subjected to the ongoing pressures of fast growth and cool temperatures to determine which of these indices are predictive of the subsequent onset of PHS. Approximately 20% of the males and females evaluated on Day 42 subsequently developed PHS by Day 51. When data for all hatches were pooled and broilers that subsequently developed ascites were compared with those that did not (nonascitic), body weights, heart rates, and percentage saturation of hemoglobin with oxygen were lower on Day 42 for ascitic than for nonascitic males, and HCT was higher in ascitic males and females than in nonascitic males and females, respectively. Comparisons of the ECG Lead II wave amplitudes for all hatches pooled indicated that RS-wave amplitude was larger in ascitic than in nonascitic males, and that S-wave amplitude was more negative in ascitic males and females than in nonascitic males and females. Necropsies conducted on Day 51 revealed higher right:total ventricular weight ratios in ascitic than in nonascitic broilers, whereas normalizing the left ventricle plus septum weight for differences in body weight generated similar values for ascitic and nonascitic males and females, respectively. These results support a primary role for pulmonary hypertension but not cardiomyopathy in the pathogenesis of ascites triggered by cool temperatures. Values obtained for minimally invasive diagnostic indices on Day 42 also establish predictive thresholds that can be used to evaluate the PHS susceptibility of large and apparently healthy male and female broilers.

    Ascites, also called pulmonary hypertension syndrome, is a metabolic disorder in chickens that have an insufficient pulmonary vascular capacity. The tendency of broilers to develop ascites is heritable, and successful selection against this susceptibility would benefit from good and easy-to-measure indicator traits. Blood gas parameters have been suggested as indicator traits for ascites susceptibility. Therefore, the aim of the present study was to estimate the heritability of blood gas parameters and the genetic and phenotypic correlations between blood gas parameters, heart ratio (postmortem indicator for ascites), and BW at 2 different ages. For this purpose, blood gas parameters, including the partial pressure of carbon dioxide in venous blood (pvCO(2)), the partial pressure of oxygen in venous blood (pvO(2)), and blood oxygen saturation, were measured at an average age of 22 d in nearly 3,000 broilers. To challenge the resistance of the birds to ascites, they were kept under cold conditions. Heritability for heart ratio was 0.43, and the heritability estimates were low: 0.02 for pvCO(2), 0.03 for pvO(2), and 0.07 for blood oxygen saturation. The estimated heritability for pH was 0.15, for bicarbonate was 0.19, and for total carbon dioxide content was 0.19. The genetic correlations between heart ratio and total carbon dioxide content (0.31 +/- 0.15) and between heart ratio and bicarbonate (0.31 +/- 0.15) were moderate and positive. For pvO(2), the genetic correlation with heart ratio was stronger and negative (-0.62 +/- 0.21); however, this correlation could not be estimated accurately because of the low heritability of pvO(2). For pvCO(2), the genetic correlation with the heart ratio was close to zero (-0.04 +/- 0.45). Phenotypic correlations between traits were, in general, similar to the genetic correlations. Heritabilities for blood gas parameters and the genetic correlations between blood gas parameters and the heart ratio estimated in the present study

    A new technique using cyanoacrylate glue is suggested for closing the transparenchymal tract following metallic endoprosthesis placement in a patient with malignant biliary obstruction complicated by ascites. With this technique, complications related to bile reflux through the transparenchymal tract would be avoided after transhepatic endoprosthesis placement in patients who have ascites. This technique would also be useful for avoiding bleeding following transhepatic portal venous puncture.

    One hundred and forty patients with an intractable ascites complicating a chronic liver disease received a peritoneovenous shunt (PVS) using the LeVeen valve. Operative mortality was ten per cent but was 25% in patients with severe liver failure. Intraoperative drainage of ascites sharply decreased postoperative complications and mortality. One-year actuarial survival rate was 81.4%, respectively 77.7%, 61.3%, and 24.7% in patients with good liver function and moderate or severe liver failure. Variceal hemorrhage occurred in 11 patients and late infection in another 11 patients. Thirty-eight patients (30.5%) had recurrence of ascites. This was mostly due to an obstruction on the venous side of the shunt. An elective portacaval shunt had to be done in 23 patients for recurrence of ascites or variceal bleeding. Among the 57 patients still alive at time of writing, 51 were free of ascites. These results suggest that PVS is an efficient operation. This procedure may be largely indicated in the selected and small group of cirrhotic patients with true intractable ascites and moderate or no liver insufficiency. Images FIG. 1. FIG. 2.

    Congenital ascites is rare, but when it occurs, urinary ascites secondary to posterior urethral valve obstruction is the most common, and tumors are the least. Among the tumors in the pediatric population, the central nervous system tumors are common, but spinal cord tumors are rare. We describe a very rare case of congenital malignant spinal cord glioma presenting as isolated congenital ascites secondary to neurogenic bladder. A female infant was diagnosed sonographically with isolated congenital ascites at 40 weeks' gestational age, with uneventful development prior to 40 weeks' gestational age. Magnetic resonance imaging of the spine done within the first week of life identified a lobulated spinal mass with heterogeneous enhancement within the conus medullaris. Spinal fluid analysis showed evidence of small round blue cells and the pathology from the excision biopsy of the mass confirmed a WHO grade III or IV malignant glioma. The postoperative course was uneventful with resolution of the ascites and spontaneous micturition. The patient was discharged home without an indwelling urinary catheter. We report the first documented case of a newborn infant with isolated congenital ascites from neurogenic bladder secondary to a spinal cord glioma. PMID:27597917

    Chronic granulomatous disease (CGD) is a rare inherited immunodeficiency syndrome that results from abnormal nicotinamide adenine dinucleotide phosphate (NADPH) oxidase function. This defect leads to recurrent catalase-positive bacterial and fungal infections as well as associated granuloma formation. We review the case of a 2-year-old boy who presented with ascites and fever of an unknown origin as manifestations of CGD. Cultures were negative for infection throughout his course, and CGD was suspected after identification of granulomas on peritoneal biopsy. Genetic testing revealed a novel mutation in the CYBB gene underlying his condition. This paper highlights the importance of considering CGD in the differential diagnosis of fever of unknown origin and ascites in children.

Injectable and hydrogel prospidin in doses from 250, 500 to 1000 mg/kg and hydrogel phosphate dextran in doses of 500 and 1000 mg/kg were administered to rats intraperitoneally in a single dose in a volume of 1 or 2 ml per each 100 g of animal body weight. The study has shown that irrespective of rats with Seidel ascites hepatoma and significantly increase in the dosage of prospidin preparations and hydrogel dextran phosphate results in a longer average life expectancy of rats Compared with its injectable variant, hydrogel prospidin appears to produce more than twice as high antineoplastic effect, and is found to provide prolonged therapeutic effects, as well as cure of animals in more than 60 % of cases.

    We present the first case report of chylous ascites following total robot-assisted donor nephrectomy. A 39-year-old female underwent a transperitoneal left-sided total robot-assisted donor nephrectomy. The procedure was uneventful and the patient was discharged without any symptoms. At postoperative Day 29, the patient presented with abdominal pain, nausea and a distended, painful abdomen with shifting dullness. She was diagnosed with chylous ascites by ultrasonography and puncture analysis, and treated with therapeutic drainage and dietary restriction. After 4 weeks, she was free of symptoms. The occurrence of this complication is rare after donor nephrectomy. Fortunately, the complication can be successfully treated within a few weeks with minimal discomfort for the patient as demonstrated in this case. It is of utmost importance to minimize the risks and limit discomfort for live kidney donors who willingly undergo major surgery to improve the well-being of another individual. PMID:27381018

    The lymphatic system is part of the circulatory system and plays a key role in normal vascular function. Its failure plays a crucial role in the development and maintenance of various diseases including liver diseases. Lymphangiogenesis (the growth of lymphatic vessels) and changes in the properties of lymphatic vessels are associated with pathogenesis of tumor metastases, ascites formation, liver fibrosis/cirrhosis and portal hypertension. Despite its significant role in liver diseases and its importance as a potential therapeutic target for those diseases, the lymphatic vascular system of the liver is poorly understood. Therefore, how the lymphatic vascular system in general and lymphangiogenesis in particular are mechanistically related to the pathogenesis and maintenance of liver diseases are largely unknown. This article summarizes: 1) the lymphatic vascular system; 2) its role in liver tumors, liver fibrosis/cirrhosis and portal hypertension; and 3) its role in ascites formation.

    Experiments on white random-bred male mice were made to study the effect of L-thyroxine on cell proliferation of the hypotetraploid strain of Ehrlich's ascites carcinoma. It was shown that prolonged thyroxine administration (during 6 days of carcinoma growth) lead to synchronization of cell proliferation and the maximum values of the mitotic index was found 3 hours earlier then in the control experiments. At the same time thyroxine did not exert any noticeable effect on the average daily magnitudes of the number of DNA-synthesizing cells and did not change the pattern of modulations in the radioactive index. The changes in the mitotic index and radioactive index were asynchronous in control and experimental animals. Analogous results were found for hyperdiploid strain of Ehrlich's ascites tumor. Ploidy of cells did not influence the tipe rhythms of the cell proliferation and its reaction on the action of thyroxine.

    An experiment with 250 one-day-old male broilers (Ross 308) was conducted to investigate the differences of some blood parameters of cold-induced ascitic and healthy broiler chicks in a 6-wk period. The chickens were divided into 2 groups of 5 replicates each. One group of these chickens was raised in normal temperature (NT) treatment and the other in cold temperature (CT) treatment to induce ascites. Mortality was necropsied daily to determine cause of death. At the end of the experiment (wk 6), 5 chickens from each replicate were randomly selected and slaughtered. The heart was removed; the right ventricle was dissected away from the left ventricle and septum. Weights of right and left ventricles were determined separately. Average BW gain and average feed intake were measured weekly, and weekly average feed conversion ratio was calculated. Serum glucose, total protein, cholesterol, triglyceride, activity of lactate dehydrogenase, as-partate aminotransferase, and alanine aminotransferase were determined. Throughout the study, the right ventricle-to-total ventricle ratio and total mortality percentage due to ascites of CT-treated birds at the end of experiment was greater (P < or = 0.05) than those of NT-treated ones. Fasting blood sugar of CT-treated birds in wk 4 and 6 was greater (P < or = 0.05) than NT-treated birds. Total blood protein of CT treatment was lower than NT-treated birds in every week and whole period, but this difference was only significant (P < or = 0.05) in wk 6. There was not a significant difference between 2 treatments for triglyceride and cholesterol, lactate dehydrogenase, aspartate aminotransferase, and alanine aminotransferase. It was concluded that cold-induced ascites could affect serum protein and fasting blood sugar of broiler chickens.

    Refractory ascites (RA) is a challenging complication after orthotopic liver transplantation. Its treatment consists of the removal of the precipitating factors. When the etiology is unknown, supportive treatment can be attempted. In severe cases, transjugular intrahepatic portosystemic shunts, portocaval shunts, and liver retransplantation have been used with marginal results. Recently, splenic artery embolization (SAE) has been described as an effective procedure for reducing portal hyperperfusion in patients undergoing partial or whole liver transplantation. Here we describe our experience with SAE for the treatment of RA. Between June 2004 and June 2010, 6 patients underwent proximal SAE for RA. Intraoperative flow measurements, graft characteristics, embolization portal vein (PV) velocities before and after SAE, and spleen/liver volume ratios were collected and analyzed. The response to treatment was assessed with imaging (ultrasound/computed tomography) and on the basis of clinical outcomes (weight changes, diuretic requirements, and the time to ascites resolution). The PV velocity decreased significantly for each patient after the embolization (median = 66.5 cm/second before SAE and median = 27.5 cm/second after SAE, P < 0.01). All patients experienced a significant postprocedural weight loss (mean = 88.1 ± 28.4 kg before SAE and mean = 75.8 ± 28.4 kg after SAE, P < 0.01) and a dramatic decrease in their diuretic requirements. All but 1 of the patients experienced a complete resolution of ascites after a median time of 49.5 days (range = 12-295 days). No patient presented with postembolization complications. In conclusion, SAE was effective in reducing the PV velocity immediately after the procedure. Clinically, this translated into a dramatic weight loss, a reduction of diuretic use, and a resolution of ascites. SAE appears to be a safe and effective treatment for RA.

    AIM: To evaluate the efficacy and safety of tolvaptan to treat refractory ascites in decompensated liver cirrhosis patients with or without further complications, such as hepatorenal syndrome and/or hepatocellular carcinoma. METHODS: Thirty-nine patients (mean age 55 years, males: 32) with decompensated liver cirrhosis and refractory ascites were enrolled. All patients received a combination of tolvaptan (15 mg/d for 5-14 d) and diuretics (40-80 mg/d of furosemide and 80-160 mg/d of spironolactone). The etiology of cirrhosis included hepatitis B (69.2%), hepatitis C (7.7%) and alcohol-induced (23.1%). Changes in the urine excretion volume, abdominal circumference and edema were assessed. The serum sodium levels were also measured, and adverse events were recorded. A follow-up assessment was conducted 1 mo after treatment with tolvaptan. RESULTS: Tolvaptan increased the mean urine excretion volume (1969.2 ± 355.55 mL vs 3410.3 ± 974.1 mL, P < 0.001), and 89.7% of patients showed improvements in their ascites, 46.2% of whom showed significant improvements. The overall efficacy of tolvaptan in all patients was 89.7%; the efficacies in patients with hepatocellular carcinoma and hepatorenal syndrome were 84.2% and 77.8%, respectively. The incidence of hyponatremia was 53.8%. In patients with hyponatremia, the serum sodium levels increased after tolvaptan treatment (from 128.1 ± 4.22 mEq/L vs 133.1 ± 3.8 mEq/L, P < 0.001). Only mild drug-related adverse events, including thirst and dry mouth, were observed. CONCLUSION: Tolvaptan is a promising aquaretic for the treatment of refractory ascites in patients with decompensated liver cirrhosis. PMID:25170228

    Background Large volume paracentesis is found to be safer and more effective for the treatment of tense ascites compared with larger-than-usual doses of diuretics according to studies. The objectives of the study was to evaluate patients with refractory ascites regarding clinical profile, technique of paracentesis, complications, amount of ascites drained, prognosis and co-morbid conditions associated with it. Methods Retrospective study was performed including patients between January 2011 and December 2013 with data pooled from total of five hospitals. A total of 4,389 paracenteses were performed on the 1,218 patients with a mean volume of 4,900 ± 2,795 mL ascitic fluid drained. Blind technique, ultrasound-guided technique of paracentesis and pig tail catheter drainage were evaluated. Diabetes mellitus data from available patients and data regarding co-morbidities were analyzed. Coagulation abnormalities in patients were studied. Results Study group age ranged from 34 to 79 years, and alcohol is the main cause of cirrhosis. Dyslipidemia was observed in 1,080 patients (88.66%). At the time of inclusion in the study, 40% of the patients had ≥ 2 other cirrhosis-related complications and 20% of the study population had ≥ 3 complications. Early complications occurred in 27.5% (337) of patients and late complications constituted 16.83% (205 patients). Conclusions Even with abnormal coagulation, paracentesis is a safe procedure. But significant co-morbidities should be addressed with care in cirrhosis patients. Ultrasound guidance during the procedure whenever required should be encouraged. PMID:27785301

    Beta-adrenergic agonists have been shown to be capable of improving growth performance in poultry when added to the feed at 1.0 ppm. However, no reference has been made concerning the cardiovascular responses when one of these agents is added to the feed at a lower concentration during the whole production cycle. The aim of this paper was to assess the effects on the ascites syndrome of 0.25 ppm clenbuterol in the feed, throughout 52 d, in broiler chicks. Results showed a lack of difference in growth and feed conversion rate between the untreated control groups and the experimental group. There were differences in mortality due to the ascites syndrome, abdominal fat:body weight ratio, and ventricular index. A statistically significant positive correlation was also found between ventricular index and mortality rate (r = 0.98). If adequate withdrawal times are ensured, the use of clenbuterol at 0.25 ppm is suggested to reduce mortality due to the ascites syndrome in broilers.

    Trisomy 7 is a frequent aneuploid change in lymphomas, adenocarcinomas, and malignant mesenchymal and neurogenic tumors. Moreover, it has been observed in cultured and uncultured non-neoplastic cells from brain, kidney, liver, lung, and atherosclerotic plaques, among other tissues, opening debate on the role of this change in normal and neoplastic tissue. We used nonradioactive in situ hybridization (ISH) with a biotinylated chromosome 7-specific alpha-satellite DNA probe to seek an extra copy of chromosome 7 in ascitic and pleural fluid interphase cells from 26 donors. The donors comprised 24 patients with nonmalignant clinical history, one patient with non-Hodgkin's malignant lymphoma (positive control), and one patient with chronic myeloid leukemia (CML, negative control). The highest frequency of fluid cells with three hybridization signals in patients without neoplasia was 0.5%, in contrast to the frequency of 40.5% noted in the fluid cells of the patient with non-Hodgkin's malignant lymphoma. The results demonstrate that the frequency of trisomic cells in pleural as well as in ascitic fluid is very low, making possible use of the cells in ascitic or pleural fluids in identification of malignancy.

    Infections are an important cause of morbidity and mortality in patients with decompensated cirrhosis and ascites. Hypothesizing that innate immune dysfunction contributes to susceptibility to infection, we assessed ascitic fluid macrophage phenotype and function. The expression of complement receptor of the immunoglobulin superfamily (CRIg) and CCR2 defined two phenotypically and functionally distinct peritoneal macrophage subpopulations. The proportion of CRIghi macrophages differed between patients and in the same patient over time, and a high proportion of CRIghi macrophages was associated with reduced disease severity (model for end-stage liver disease) score. As compared with CRIglo macrophages, CRIghi macrophages were highly phagocytic and displayed enhanced antimicrobial effector activity. Transcriptional profiling by RNA sequencing and comparison with human macrophage and murine peritoneal macrophage expression signatures highlighted similarities among CRIghi cells, human macrophages, and mouse F4/80hi resident peritoneal macrophages and among CRIglo macrophages, human monocytes, and mouse F4/80lo monocyte-derived peritoneal macrophages. These data suggest that CRIghi and CRIglo macrophages may represent a tissue-resident population and a monocyte-derived population, respectively. In conclusion, ascites fluid macrophage subset distribution and phagocytic capacity is highly variable among patients with chronic liver disease. Regulating the numbers and/or functions of these macrophage populations could provide therapeutic opportunities in cirrhotic patients. PMID:27699269

    AIM: To evaluate the accuracy of spot urinary Na/K and Na/creatinine (Cr) ratios as an alternative to 24-h urinary sodium in monitoring dietary compliance in patients with liver cirrhosis and ascites treated with diuretics. METHODS: The study was carried on 40 patients with liver cirrhosis and ascites treated with diuretic therapy. Patients were divided into two groups according to 24-h urinary sodium. We measured spot urine Na/K ratio, Na/Cr ratio and 24-h urinary sodium. Student’s t test was used to compare the interval variables and χ2 test to compare the nominal variables between the two groups. Receiver operator characteristic curve was used to identify the best cutoff point for Na/K and Na/Cr ratio. RESULTS: The best cutoff point for Na/K ratio was 2.5 (P < 0.001) and area under the curve (AUC) was 0.9, and for Na/Cr ratio, the best cutoff point was 35 (P < 0.001) and AUC was 0.885. Na/K ratio showed higher sensitivity and accuracy compared to Na/Cr ratio (87.5% and 87% for Na/K ratio; 81% and 85% for Na/Cr ratio, respectively). CONCLUSION: Spot urine Na/K ratio has adequate accuracy for assessment of dietary sodium restriction compared with 24-h urinary sodium in patients with liver cirrhosis and ascites. PMID:19653340

    Pulmonary hypertension is a common finding in patients with advanced liver disease. Similarly, among patients with advanced pulmonary arterial hypertension, right heart failure leads to congestive hepatopathy. Diuretic resistant fluid overload in both advanced pulmonary hypertension and chronic liver disease is a demanding challenge for physicians. Venous congestion and ascites-induced increased intra-abdominal pressure are essential regarding recurrent hospitalization, morbidity and mortality. Due to impaired right-ventricular function, many patients cannot tolerate extracorporeal ultrafiltration. Peritoneal dialysis, a well-established, hemodynamically tolerated treatment for outpatients may be a good alternative to control fluid status. We present a patient with pulmonary arterial hypertension and congestive hepatopathy hospitalized for over 3 months due to ascites induced refractory volume overload treated with peritoneal ultrafiltration. We report the treatment benefits on fluid balance, cardiorenal and pulmonary function, as well as its safety. In conclusion, we report a case in which peritoneal ultrafiltration was an efficient treatment option for refractory ascites in patients with congestive hepatopathy.

    Ascites is a metabolic disorder that accounts for over 25% of overall mortality in the broiler industry. This disorder is manifested between wk 5 and 6 posthatch, but there are previous indications that predisposition may be identified during embryonic development. In this current study, we determined embryonic physiological and metabolic parameters that may be associated with ascites predisposition. For this purpose, we used broiler eggs from 3 lines that differed in ascites sensitivity. These included an ascites-sensitive dam line (DAS), an ascites-resistant dam line (DAR), and an ascites-sensitive sire line (SASL). Eggs were incubated for 21 d under standard conditions. The following parameters were measured during incubation: egg weights at setting, egg weight losses at 18 d, embryo body weights and embryo heart weights throughout development, air cell partial gas pressures (pCO2 and pO2) levels at d 18 and at internal pipping (IP); plasma triiodothyronine, thyroxine, and corticosterone levels at d 18, IP, and hatch; heat production from d 17 until hatch, hematocrit values at hatch, and posthatch growth rate to 7 d along with hematocrit values. The data obtained revealed that selection for ascites sensitivity or rapid growth rate had no consistent influence on some of these parameters such that they could be wholly associated with ascites sensitivity for predictive purposes. Whereas differences in embryonic developmental patterns were apparent throughout embryonic development, these differences in physiological and metabolic parameters may be due partly to genetic differences unrelated to ascites sensitivity.

    Objective To study the prevalence and predictive factors of spontaneous bacterial peritonitis (SBP) in patients of cirrhosis with ascites and to study the clinical characteristics and prognosis of patients with SBP. Materials and Methods The present study was conducted on 122 cases admitted in Department of Medicine, through emergency, in Guru Gobind Singh Medical College and Hospital, Faridkot, Punjab, India. Cases of cirrhosis (irrespective of aetiology) with ascites between the ages of 18-75 years were included in this study. Ascitic fluid of every patient was aspirated under all aseptic measures, before initiation of antibiotic therapy and was sent for biochemical analysis, culture and cytological analysis. Results Mean age of patients enrolled was 50.30± 10.98 years. 85% were male and 15% were female. Alcohol (73.8%) was the leading cause of cirrhosis followed by HCV (37.7%) and HBV (4.9%). Of the 122 patients studied, 27 (20.4%) patients were diagnosed as having SBP and its variants. Monomicrobial Bacterascites (BA) was present in 5 patients and Culture Negative Neutrocytic Ascites (CNNA) was present in 22 patients. Escherichia coli were the most common isolated organism followed by Klebsiella. The various factors that predispose to development of SBP include low ascitic fluid protein concentration, a high level of serum bilirubin, deranged serum creatinine, high Child-Pugh score and high MELD score. Conclusion Ascitic fluid analysis remains the single most important test for identifying and assessing a course of SBP. Bedside inoculation of 10-20ml of ascitic fluid into culture bottle at patient bedside will yield better results. Early diagnosis and treatment will reduce the mortality rate in these patients.

    The binding of Ricinus communis lectins to HeLa cells, Sarcoma 180 ascites tumor cells and human erythrocytes was studied in detail. Scatchard plots of binding of 125I-lectins to these cells gave biphasic lines except for HeLa cells at 0 degree C. The association constants of lectins for the three cell types at 37 degrees C were lower than those at 0 degree C. The numbers of total binding sites were estimated to be 7 to 16 X 10(7) per HeLa cell, 3 to 4 X 10(7) per Sarcoma 180 ascites tumor cell and 0.4 to 1 X 10(6) per erythrocyte. A fraction, 16 to 27% of the total amount of cell-bound lectin at 37 degrees C, appeared to be bound irreversibly as judged by non-removal on washing with 0.1 M lactose, whereas no lectin was irreversibly bound at 0 degree C. In the case of erythrocytes, no lectin became irreversibly bound even at 37 degrees C. The toxicity of lectins on HeLa cells and Sarcoma 180 ascites tumor cells was investigated. The toxicity of ricin D was 50 times for Sarcoma 180 ascites tumor cells and 140 times for HeLa cells as much as that for castor bean hemagglutinin. As to the sensitivities of both cell types to these lectins, it became apparent that Sarcoma 180 ascites tumor cells were more susceptible than HeLa cells.

    Ovarian cancer ascites consist of a proinflammatory environment that is characterized by the presence of abundant human peritoneal mesothelial cells (HPMCs). Cytokines and growth factors in ascites modulate cell activities of tumor cells. The expression of proinflammatory cytokines in ascites is associated with a more aggressive tumor phenotype. The effect of ascites on HPMCs is for the most part unknown but this interplay is thought to be important for epithelial ovarian cancer (EOC) progression. Here, we examine the components of ascites, which stimulate patient-derived HPMC migration, from women with advanced EOC. We show that ovarian cancer ascites enhanced the migration of HPMCs. This effect was inhibited by heat treatment, hepatocyte growth factor (HGF) blocking antibodies and a HGF receptor (cMet) inhibitor. In ovarian cancer ascites, HGF is present at high concentration compared to benign fluids. Ascites-mediated activation of cMet was associated with Akt and EKR1/2 phosphorylation. This response was partly inhibited by heat treatment and cMet inhibitor. Ascites-induced migration and a cMet phosphorylation were strongly inhibited by epidermal growth factor receptor (EGFR) inhibitor PD153035, suggesting the transactivation of cMet by EGFR. Our study suggests that HGF and ligands of EGFR are factors that mediate ovarian cancer ascites-mediated migration of HPMCs by activating cMet and possibly downstream ERK1/2 and Akt pathways. The study provides evidence for the first time that ascites not only support tumor growth but also enhance the migratory potential of cancer-associated mesothelial cells, which in turn may support cancer progression.

  12. Changes in gut bacterial populations and their translocation into liver and ascites in alcoholic liver cirrhotics

    PubMed Central

    2014-01-01

    Background The liver is the first line of defence against continuously occurring influx of microbial-derived products and bacteria from the gut. Intestinal bacteria have been implicated in the pathogenesis of alcoholic liver cirrhosis. Escape of intestinal bacteria into the ascites is involved in the pathogenesis of spontaneous bacterial peritonitis, which is a common complication of liver cirrhosis. The association between faecal bacterial populations and alcoholic liver cirrhosis has not been resolved. Methods Relative ratios of major commensal bacterial communities (Bacteroides spp., Bifidobacterium spp., Clostridium leptum group, Enterobactericaea and Lactobacillus spp.) were determined in faecal samples from post mortem examinations performed on 42 males, including cirrhotic alcoholics (n = 13), non-cirrhotic alcoholics (n = 15), non-alcoholic controls (n = 14) and in 7 healthy male volunteers using real-time quantitative PCR (RT-qPCR). Translocation of bacteria into liver in the autopsy cases and into the ascites of 12 volunteers with liver cirrhosis was also studied with RT-qPCR. CD14 immunostaining was performed for the autopsy liver samples. Results Relative ratios of faecal bacteria in autopsy controls were comparable to those of healthy volunteers. Cirrhotics had in median 27 times more bacterial DNA of Enterobactericaea in faeces compared to the healthy volunteers (p = 0.011). Enterobactericaea were also the most common bacteria translocated into cirrhotic liver, although there were no statistically significant differences between the study groups. Of the ascites samples from the volunteers with liver cirrhosis, 50% contained bacterial DNA from Enterobactericaea, Clostridium leptum group or Lactobacillus spp.. The total bacterial DNA in autopsy liver was associated with the percentage of CD14 expression (p = 0.045). CD14 expression percentage in cirrhotics was significantly higher than in the autopsy controls (p = 0

    MircoRNA’s (miR) have been recognised as important modulators of gene expression and potential biomarkers. However, they have been rarely investigated in bio fluids apart from blood. We investigated the association of miR-125b and miR-155 with complications of cirrhosis. Ascites was prospectively collected from patients with cirrhosis undergoing paracentesis at our department. miR’s were determined in the supernatant using qPCR and normalized by SV-40. Clinical parameters were assessed at paracentesis and during follow-up. 76 specimens from 72 patients were analysed. MiR’s were not associated to age, sex or aetiology of cirrhosis. MiR-125b levels differed between patients with low and high MELD score, and miR-125b levels showed an inverse correlation to serum creatinine (r2 = −0.23; p = 0.05). MiR-155 was elevated in patients with spontaneous bacterial peritonitis (SBP) (n = 10; p = 0.04). MiR-155 levels differed between patients with and without 30-day survival (p = 0.02). No association of ascites levels of investigated miR’s to size of varices, episodes of gastrointestinal bleeding or hepatorenal syndrome was observed. While miR-125b levels in ascites seem to be associated with liver and renal dysfunction, miR-155 might be implicated in local immune response in SBP. PMID:28074870

    Congenital leukemias are a rare group of hematologic neoplasms with a wide range of clinical signs and symptoms. Here we reported a neonate presenting with jaundice, pleural effusion and ascites. The total protein and serum albumin were markedly low at 48 and 12 g/L. Computerized tomography showed the density of liver was asymmetry with several hypoechoic regions. Initial blood routine examination revealed only thrombocytopenia while blood white cells increased to 30.0×10(9)/L with 17% blast cells several days later. Bone marrow biopsy showed the proportion of blasts and promonocytes increased and she was diagnosed as acute monoblastic leukemia.

    A hypothesis was tested that providing the breeder hens with exogenous thyroxine (T(4)) would help their offspring to better survive the ascites-inducing condition during the growing period. In total, 132 broiler breeder hens were randomly assigned to one of 3 treatments: control (CON), hypothyroid [HYPO; 6-N-propyl-2-thiouracil (PTU)-treated], and hyperthyroid (HYPER; T(4)-treated). The hens were artificially inseminated, and the hatching eggs (n = 1,320) were incubated. No eggs in the HYPO group hatched. The 1-d-old male chicks (n = 288) from other groups were reared for 42 d under standard or low ambient temperature to induce ascites. Blood samples were drawn from the hens, embryos, and broilers for determination of T(4) and triiodothyronine (T(3)). The hematocrit was also determined in broilers. The PTU-treated hens had an increased BW along with lower plasma T(3) and T(4) concentrations. Plasma T(4) was higher in the HYPER hens compared with CON hens, but T(3) concentration was not different between these groups. The fertility rate was not affected by either hypo- or hyperthyroidism. The embryos in the HYPO group had lower plasma T(3) and T(4) concentrations at d 18 of embryonic development and internal pipping. Higher plasma T(4) was recorded in the HYPER birds at internal pipping, although plasma T(3) concentration was not affected at this stage. Maternal hyperthyroidism decreased the overall incidence of ascites in the cold-exposed chickens (10.0 vs. 33.4% for HYPER and CON groups, respectively). Although the effect of maternal PTU or T(4) treatment on plasma thyroid hormones and on the right ventricle-to-total ventricular weight ratio in the broilers was not significant, the cold-exposed healthy CON chicks showed higher hematocrit values, compared with the HYPER birds. It was concluded that maternal hyperthyroidism could decrease the incidence of cold-induced ascites in broiler chickens; however, probable causal mechanisms remain to be elucidated.

    The aim of the current study was to determine how a control temperature and acute and chronic high eggshell temperatures during the last three days of incubation, can affect hatchability, chick quality, and organ development on day of hatch as well as broiler performance and ascites incidence in later life. The eggshell temperature manipulations were applied during hatching term (days 19 to 21) as follows: control EST (37.3 to 38.0°C), acute high eggshell temperature manipulations (38.4- to 39.0°C for three hours daily) and chronic high eggshell temperature manipulations (38.4 to 39.0°C). The lowest hatchability and the highest cull chick rate were in the chronic high eggshell temperature manipulations group. Lower chick quality parameters correlated with lower chick weights and heavier residual yolk sac weights that were in the chronic high eggshell temperature manipulations group depending on hatch time. The live weights on the 1(st) day of the growing period were higher in the control and acute high eggshell temperature manipulations groups than the chronic high eggshell temperature manipulations group. At 6 wk of age, live weights of broilers were the highest in the control than in the acute and chronic high eggshell temperature manipulations groups. The total mortality was 2.5, 9.2, and 13.3%, the mortality due to ascites was 2.1, 8.3, and 12.9% in the control, acute ,and chronic high eggshell temperature manipulations groups, respectively. The right ventricular/total ventricular ratios for the control, acute and chronic high eggshell temperature manipulations groups were 0.22, 0.28, and 0.30%, respectively. In conclusion, short-term and long-term higher temperatures during the hatching term affect embryo development, incubation results, broiler performance, and ascites incidence. Although the acute high eggshell temperature manipulations did not affect the chick quality parameters at hatch, it negatively affected incubation results and broiler performance

    Two patients with pancreatic malignancies presented with biliary obstruction which could not be treated from an endoscopic approach. Standard transhepatic biliary drainage was relatively contraindicated because of moderate ascites and coagulopathy related to underlying liver disease. In one patient, a transjugular, transvenous approach was used to deliver a Wallstent endoprosthesis across the distal common bile duct obstruction in a single step procedure. In the second case, a previously placed biliary Wallstent was revised with an additional stent from a similar approach. Transjugular biliary catheterization offers a valuable alternative approach for primary stent placement or revision in patients with contraindication to standard transhepatic drainage.

    Leiomyosarcoma is one of the soft tissue sarcomas that could originate from different parts of body and are mostly presented as retropritoneal mass. Leiomyosarcomas of vascular origin are particularly rare tumors occurring mainly in inferior vena cava (IVC). Here, we report the case of a 35-year-old male patient who presented with ascites and jaundice. Further evaluation revealed large hepatic and cardiac masses with extension to IVC. Since it was not possible to determine the point of origin of leiomyosarcoma, the patient received chemotherapy under diagnosis of metastatic leiomyosarcoma but unfortunately passed away.

    An 11-yr-old female cheetah (Acinonyx jubatus) was diagnosed clinically with hepatic and renal disease and euthanatized after an extended illness. Postmortem examination revealed 8-10 L of milky white fluid in the abdominal cavity and markedly dilated lymphatic vessels within the intestinal mesentery. The abdominal fluid was a chylous effusion based on the cytologic predominance of lymphocytes and macrophages and comparison of cholesterol and triglyceride levels in the fluid and in serum. Gross and histopathologic lesions in the liver were consistent with a diagnosis of venoocclusive liver disease. Chylous ascites is uncommon with human chronic liver disease and is rarely identified in animals.

    We present the case of a female patient with arrhythmogenic dysplasia of the right ventricle who evolved to refractory heart failure, ascites, and peripheral edema. As a result, heart transplantation was performed. Subsequently, refractory ascites impaired the patient's respiratory function, resulting in prolonged mechanical ventilation. She was successfully treated with transjugular intrahepatic portosystemic shunt (TIPSS) placement, which allowed satisfactory weaning of ventilatory support.

    Ascites is a prevalent cardiovascular disease among modern broilers with negative impacts on production and animal welfare. The peak of mortality due to ascites occurs at the end of the growing period, but the etiology of this problem may start during embryonic development. A few recent reports have demonstrated that the signs of ascites susceptibility are manifested during the late stages of incubation. In the current study, we used a nondestructive method based on egg acoustic resonance parameters [resonant frequency (RF) and damping] to establish a relationship between embryo physiological events during early development in broiler eggs and susceptibility to ascites. The hatching eggs of 3 broiler lines differing in ascites susceptibility were used for this study: ascites-resistant dam line (DAR), ascites-sensitive dam line (DAS), and ascites-sensitive sire line (SASL). These lines were selected on the basis of fast growth, high breast meat yield, and ascites induction at low temperatures such that the order of ascites susceptibility in terms of mortality was SASL > DAS > DAR. Eggs were incubated under standard conditions in forced-draft incubators. We measured egg weights at setting, albumen pH, Haugh units (HU) at setting, and embryo weights at d 11 and 18, at internal pipping (IP), and at hatch. The durations of IP, external pipping (EP), and hatching were also determined. At 2 hourly periods during incubation, egg RF and damping were also measured. There were differences in egg weights between DAR and SASL vs. DAS, but albumen HU, albumen pH, and the ratio of yolk weight to egg weight were similar. There were differences in RF, damping, embryonic growth rates, and hatching events. Changes in resonant frequency and damping, which certainly suggest eggshell differences among lines, were not totally related to variations in physiological events during early and late embryonic development.

    Glycogen phosphorylase a activity in 7 rat ascites hepatoma cell lines treated with adrenergic agents, phenylephrine, epinephrine and isoproterenol, was investigated as compared with that in freshly isolated rat hepatocytes. Basal phosphorylase activities in hepatoma cells except AH7974 cells were lower than that in hepatocytes. Phosphorylase in hepatoma cells was not activated by any of the agents, while the enzyme activity in hepatocytes was clearly increased in a dose- and time-dependent manner. Phosphorylase in hepatocytes was sensitive to glucagon, but it was found to be insensitive to glucagon in all hepatoma cells. The present results suggest that rat ascites hepatoma cells may escape the glycogenolytic regulation by catecholamines and glucagon.

    The inhibitory effects of a new boron compound of guanidine biboric acid adduct (GB) and guanidium chloride (L1) on the growth of ascites tumour in female Swiss mice were studied by monitoring the survival, tumour weight, tumour cell count, transplantability of Ehrlich ascites cells, precursor incorporation and the haematological parameters of the treated mice. 5-Fluorouracil, a known anticancer drug, was used as a positive control. The most important parameter was the survival time, which increased significantly when tumour-bearing mice were treated with the boron compound. Haematological parameters of the treated animals showed minimum toxic effects when boron was coupled with guanidine.

    Despite initial response to chemotherapy, at least 50% of ovarian cancer patients will relapse within 18 months. Progression-free survival is related to tumour infiltration with cytotoxic T lymphocytes (CTL). We recently demonstrated that CD8+ T cell responses to recall antigens improve following tumour response to chemotherapy. Vaccination designed to expand CTL, specific for tumour-associated antigens, may be a means of improving outcome. We are planning a clinical trial in advanced ovarian cancer patients undergoing chemotherapy using a combination of a Toll-like receptor 3 (TLR3) agonist and tumour-associated ascites-derived exosomes. Tumour-derived exosomes are a potential source of tumour antigens able to induce CD8+ T cell responses when loaded on mature dendritic cells (DC). DC maturation can be achieved with Toll-like receptor (TLR) agonists, such as the GMP-grade synthetic double stranded RNA, poly[I]:poly[C12U] (Ampligen) which is a TLR-3 agonist. Here, we describe the development of a method suitable for the preparation of GMP-grade exosomes from the ascites fluid of ovarian cancer patients, and the methods used for the molecular and immunological characterisation of these exosomes preceding their use in a clinical trial.

    Calcium signaling has been reported to be involved in the pathogenesis of hypertension. Verapamil, one of the calcium antagonists, is used to characterize the role of calcium signaling in the development of pulmonary arterial hypertension syndrome in broilers. The suppression effect of verapamil on pulmonary arterial hypertension and pulmonary vascular remodeling was examined in broilers, from the age of 16 days to 43 days. Our results showed that oral administration of lower dose of verapamil (5 mg/kg body weight every 12 h) prevented the mean pulmonary arterial pressure, the ascites heart index and the erythrocyte packed cell volume of birds at low temperature from increasing, the heart rate from decreasing, and pulmonary arteriole median from thickening, and no pulmonary arteriole remodeling in broilers treated with the two doses of verapamil at low temperature was observed. Our results indicated that calcium signaling was involved in the development of broilers' pulmonary arterial hypertension, which leads to the development of ascites, and we suggest that verapamil may be used as a preventive agent to reduce the occurrence and development of pulmonary arterial hypertension in broilers.

    1979-06-10

    Initial rate measurements of the stoichiometric relationships between H+ ejection, K+ and Ca2+ uptake, and electron transport were carried out on mitochondria from Ehrlich ascites tumor cells grown in mice. With succinate as substrate and N-ethylmaleimide to prevent interfering H+ reuptake via the phosphate carrier, close to 8 H+ were ejected per oxygen atom reduced (H+/O ejection ratio = 8.0); with the NAD-linked substrates pyruvate or pyruvate + malate, the H+/O ejection ratio was close to 12. The average H+/site ratio (H+ ejected/2e-/energy-conserving site) was thus close to 4. The simultaneous uptake of charge-compensating cations, either K+ (in the presence of valinomycin) or Ca2+, was also measured, yielding average K+/site uptake ratios of very close to 4 and Ca2+/site ratios close to 2. It was also demonstrated that each calcium ion enters the respiring tumor mitochondria carrying two positive electric charges. These stoichiometric data observed in mitochondria from Ehrlich ascites tumor cells thus are in complete agreement with similar data on normal rat liver and rat heart mitochondria and suggest that the H+/site ratio of mitochondrial electron transport may be 4 generally. It was also observed that the rate of deltaH+ back-decay in anaerobic tumor mitochondria following oxygen pulses is some 6- to 8-fold greater than in rat liver mitochondria tested at equal amounts of mitochondrial protein.

  8. Inhibition of oxidative phosphorylation in ascites tumor mitochondria and cells by intramitochondrial Ca2+.

    Accumulation of Ca2+ (+ phosphate) by respiring mitochondria from Ehrlich ascites or AS30-D hepatoma tumor cells inhibits subsequent phosphorylating respiration in response to ADP. The respiratory chain is still functional since a proton-conducting uncoupler produces a normal stimulation of electron transport. The inhibition of phosphorylating respiration is caused by intramitochondrial Ca2+ (+ phosphate). ATP + Mg2+ together, but not singly, prevents the inhibitory action of Ca2+. Neither AMP, GTP, GDP, nor any other nucleoside 5'-triphosphate or 5'-diphosphate could replace ATP in this effect. Phosphorylating respiration on NAD(NADP)-linked substrates was much more susceptible to the inhibitory effect of intramitochondrial Ca2+ than succinate-linked respiration. Significant inhibition of oxidative phosphorylation is given by the endogenous Ca2+ present in freshly isolated tumor mitochondria. The phosphorylating respiration of permeabilized Ehrlich ascites tumor cells is also inhibited by Ca2+ accumulated by the mitochondria in situ. Possible causes of the Ca2+-induced inhibition of oxidative phosphorylation are considered.

    Eighty % of ovarian cancer patients diagnosed at an advanced-stage have complete remission after initial surgery and chemotherapy. However, most patients die within <5 years due to episodes of recurrences resulting from the growth of residual chemoresistant cells. In an effort to identify mechanisms associated with chemoresistance and recurrence, we compared the expression of proteins in ascites-derived tumor cells isolated from advanced-stage ovarian cancer patients obtained at diagnosis (chemonaive, CN) and after chemotherapy treatments (chemoresistant/at recurrence, CR) by using in-depth, high-resolution label-free quantitative proteomic profiling. A total of 2,999 proteins were identified. Using a stringent selection criterion to define only significantly differentially expressed proteins, we report identification of 353 proteins. There were significant differences in proteins encoding for immune surveillance, DNA repair mechanisms, cytoskeleton rearrangement, cell-cell adhesion, cell cycle pathways, cellular transport, and proteins involved with glycine/proline/arginine synthesis in tumor cells isolated from CR relative to CN patients. Pathway analyses revealed enrichment of metabolic pathways, DNA repair mechanisms and energy metabolism pathways in CR tumor cells. In conclusion, this is the first proteomics study to comprehensively analyze ascites-derived tumor cells from CN and CR ovarian cancer patients. PMID:27470985

    Decompensated liver cirrhosis (LC), a life-threatening complication of chronic liver disease, is one of the major indications for liver transplantation. Recently, mesenchymal stem cell (MSC) transfusion has been shown to lead to the regression of liver fibrosis in mice and humans. This study examined the safety and efficacy of umbilical cord-derived MSC (UC-MSC) in patients with decompensated LC. A total of 45 chronic hepatitis B patients with decompensated LC, including 30 patients receiving UC-MSC transfusion, and 15 patients receiving saline as the control, were recruited; clinical parameters were detected during a 1-year follow-up period. No significant side-effects and complications were observed in either group. There was a significant reduction in the volume of ascites in patients treated with UC-MSC transfusion compared with controls (P < 0.05). UC-MSC therapy also significantly improved liver function, as indicated by the increase of serum albumin levels, decrease in total serum bilirubin levels, and decrease in the sodium model for end-stage liver disease scores. UC-MSC transfusion is clinically safe and could improve liver function and reduce ascites in patients with decompensated LC. UC-MSC transfusion, therefore, might present a novel therapeutic approach for patients with decompensated LC.

    When Erhlich ascites tumor and normal mouse liver extracts were incubated with (/sup 3/H-CH/sub 3/)-S-adenosylmethionine and E. coli tRNA, the tumor extracts had a ten-fold higher methyltransferase activity than mouse liver extracts. However, only a two-fold higher methyltransferase activity was observed when methyl deficient mouse liver tRNA was used as a substrate. DEAE-Sephadex chromatography of alkaline hydrolysates of methyl deficient mouse liver tRNA (tRNA isolated from mice treated with ethionine) showed 70% of the /sup 3/H-methyl groups in the mononucleotide peak and 30% in alkaline stable di-, tri- and oligonucleotide peaks demonstrating methylation of both the base and ribose moieties. Perchloric acid digest of material isolated from the di-, tri- and oligonucleotide peaks confirm that the /sup 3/H-methyl groups are on the ribose moieties. In hydrolysates of E. coli tRNA /sup 3/H-methyl groups appeared in only the mononucleotide peak, i.e. only base methylation. These data, from Erhlich ascites cells, suggest that ribose methyltransferases may have greater RNA substrate specificity than the base methyltransferases and may act processively to produce alkaline stable oligonucleotides.

    The present study was designed to compare the anatomical parameters of the cardiopulmonary system in three different lines of chickens with different susceptibility to ascites syndrome. Eggs from three different genetic lines-commercial broiler and layer lines and one native to Iran--were incubated and hatched, and 1-day-old chicks used. The relative heart and lung weights, the volumes of the heart, lung and thorax cavity, the incidence of ascites, and the related physiological parameters in these chickens were followed. Lung weight as a percentage of body weight, the relative lung and heart volume, and the volumes of the thorax cavity, before and after removing heart and lung tissues, were lower in fast-growing broiler chickens compared with the layer and native chickens. Additionally, most of these parameters (e.g. relative lung weight, lung volume and thorax cavity) were significantly decreased with age in broiler chickens but were increased in layer and native chickens, which was concomitant with the incidence of ascites in broiler chickens. Our data indicate that all cardiopulmonary parameters investigated are extremely unfavourable to broiler chickens and suggest a reduction in gas exchange area in broilers, and therefore higher susceptibility to pulmonary hypertension and ascites.

    Intraperitoneal administration of concanavalin A (ConA, 25 mg/kg b.w.), a cell-binding plant lectin was used for inducing inflammatory ascites, and potential inhibitors were tested in 1 h and 2.5 h experiments, i.e. still before the major influx of leucocytes. At the end of the experiment the peritoneal fluid was collected and measured. The ConA-induced ascites was significantly (p<0.01) and dose-dependently inhibited by icatibant (HOE-140), a synthetic polypeptide antagonist of bradykinin receptors. Aprotinin, a kallikrein inhibitor protein also had significant (p<0.01), but less marked inhibitory effect. L-NAME, an inhibitor of NO synthesis, and atropine methylnitrate, an anticholinergic compound, were ineffective. It is concluded, that the kallikrein/kinin system contributes to the mediation of the ConA-induced ascites by increasing subperitoneal vascular permeability, independent of the eventual vasodilation produced by NO. It is known, that membrane glycoproteins are aggregated by the tetravalent ConA and the resulting distortion of membrane structure may explain the activation of the labile prekallikrein. Complete inhibition of the ConA-induced ascites could not be achieved by aprotinin or icatibant, which indicates the involvement of additional mediators.

    An 85-year-old woman was admitted to our hospital for steroid therapy for relapsing nephrotic syndrome. During hospitalization, she complained of sudden epigastric pain at night. Although there were signs of peritoneal irritation, CT showed a large amount of ascitic fluid, but no free intraperitoneal gas. Gram staining of ascitic fluid obtained by abdominal paracentesis showed Gram-negative rods, which raised a strong suspicion of gastrointestinal perforation and peritonitis. Therefore, emergency surgery was performed. Exploration of the colon showed multiple sigmoid diverticula, one of which was perforated. The patient underwent an emergency Hartmann's procedure. Imaging studies failed to reveal any evidence of gastrointestinal perforation, presenting a diagnostic challenge. However, a physician performed rapid Gram staining of ascitic fluid at night when laboratory technicians were absent, had a strong suspicion of gastrointestinal perforation, and performed emergency surgery. Gram staining is superior in rapidity, and ascitic fluid Gram staining can aid in diagnosis, suggesting that it should be actively performed. We report this case, with a review of the literature on the significance of rapid diagnosis by Gram staining.

    Herpes simplex virus (HSV) infection is usually observed in the oral cavity and external genitals, and HSV peritonitis is extremely rare. Herein, we report a case of type II HSV peritonitis successfully diagnosed by ascitic cytology. A 66-year-old Japanese man, who had been treated with steroid inhalation for 5 years due to chronic obstructive pulmonary disease, was suspected to have acute cholecystitis. Laparoscopic cholecystectomy and intraoperative cytological examination of ascitic fluid were performed. Cytological study of ascitic fluid revealed that abundant granular cell debris, degenerative cells and apoptotic bodies were present, as well as some single or multinucleated cells with ground glass nuclei. However, vivid mesothelial cells were rarely seen. Immunocytochemical staining for type II HSV was positive in single or multinucleated cells with ground glass nuclei. Therefore, a diagnosis of type II HSV peritonitis was made. This is the first reported case of type II HSV peritonitis successfully diagnosed by ascitic cytology. This report highlights that the presence of abundant cell debris, degenerative cells and apoptotic bodies, and the absence of vivid mesothelial cells are the key cytological findings to suspect HSV peritonitis, and the diagnosis can be confirmed by careful surveillance for characteristic nuclear findings of single or multinucleated cells. The frequency of opportunistic infection is increased because of the increased numbers of iatrogenic immunocompromised patients as seen in this case, therefore, cytological examination is a useful method for early detection of the causative agent of peritonitis including HSV.

    The effects of diurnal temperature fluctuations and removal of respirable dust, by application of canola oil to straw litter, on growth, carcass traits, and the degree of ascites was evaluated with 1,200 male broilers studied in two replicated 6-wk trials. Each trial used four pens of 150 birds. The temperature treatment consisted of a fluctuation of 3 C in temperature above the required temperature during the day (0600 to 1800 h) and 3 C below the required temperature at night (1800 to 0600 h) for a 6 C change in daily temperature. The control temperature was constant. All pens had the same mean daily temperature. In each trial, one control temperature pen and one fluctuation temperature pen received bi-weekly applications of canola oil to the litter (1.1 L/m2 of oil over 6 wk). At 6 wk of age, 30 birds from each pen were killed for determination of breast muscle, fatpad, and heart weights. All birds were scored for lesions of ascites at time of processing. A score of 0 or 1 represented slight pericardial effusion, slight pulmonary congestion, and edema. A score of 4 represented birds with marked accumulation of ascitic fluid in one or more ceolomic cavities (other than the pericardium) and advanced liver lesions. A cross-sectional image of each 4-mm heart slice (cross-section of the ventricles) was digitally recorded, and with image analysis we determined the right ventricular area (RVA), left ventricular area (LVA), and total heart area (HA). The final BW of the broilers were significantly different, the oiled-litter treatment (2,249 g) had lower weight gain compared with the nonoiled litter treatment (2,293 g). There were no differences in fatpad weight, shank length, lung weight, and percentage breast muscle between the main treatments. The Pectoralis minor and Pectoralis major weight were significantly heavier in the temperature fluctuation treatment than in the control temperature treatment by 3.0 and 12.0 g, respectively.

    Background The diagnosis of peritonitis as a complication of cirrhosis is an important clinical problem. Objectives The aim of this study was to evaluate serum C-reactive protein levels as a diagnostic factor for spontaneous bacterial peritonitis (SBP) in child patients with liver disease. Methods In this study, 150 children diagnosed with liver disease and ascites upon admission to Nemazee Teaching Hospital (Shiraz, Iran) were examined. Patients were divided into spontaneous bacterial peritonitis and sterile ascetic fluid groups according to the PMN count ≥ 250/mm3 in the ascetic fluids. Routine laboratory tests were conducted and quantitative C-reactive protein (CRP) levels were measured for all of the patients. Accuracy, sensitivity, and specificity of CRP was evaluated for diagnosis of SBP. Results Of 150 cirrhotic patients, 109 patients presented without SBP (52.29% male, mean age: 5.02 ± 4.49 years) and 41 patients presented with SBP (51.21% male, mean age: 4.71 years). Cell counts, protein levels, albumin levels, and lactate dehydrogenize (LDH) levels of the ascetic fluid and serum samples in the SBP group were higher than the rates for those without SBP (P < 0.05(. The mean ± SD of CRP in the SBP group (36.89 ± 23.43) increased significantly compared to the rate among those without SBP (21.59 ± 15.43, P = 0.001). The percentages for sensitivity and specificity of CRP, the diagnosis of SBP based on the PMN count ≥ 250/mm3, and cultured ascites were 69.23%, 90.25%, 88.43%, and 84.32%, respectively. The areas under the curve of CRP for SBP based on the PMN count ≥ 250/mm3 and cultured ascites was 0.94 (CI 95%: 0.90 to 0.96) and 0.85 (CI 95%: 0.84 to 0.92), respectively (P < 0.001). Conclusions Our study showed that CRP is a marker with high sensitivity and specificity for the diagnosis of SBP in cirrhotic children. PMID:27795726

    Although massive cirrhotic ascites is generally considered a contraindication for the placement of percutaneous endoscopic gastrostomy (PEG), such patients are usually poorly nourished. Preceding paracentesis of ascites is one method for controlling ascites and allowing the safe placement of PEG, but it often results in overuse of albumin. Preceding peritoneal-venous (P-V) shunting can avoid excessive use of albumin, but this introduces the risk of infectious contamination. We encountered an 88-y-old woman with massive cirrhotic ascites, a giant esophageal hernia with dislocation of the proximal stomach into the mediastinum, hypertrophy of the lateral segment of the liver, and malnutrition who had suffered from appetite loss and a swallowing disorder for 4 mo. She underwent PEG using a staged sequential introduction method using a Funada-style gastric wall fixation kit as follows: 1) full stretching and pushing out of the stomach from the mediastinum into the peritoneal cavity by deep insertion and a turning-over procedure of the endoscope, 2) full distention by air to adhere the gastric wall to the peritoneal wall without migration of the colon, 3) four-point square fixation under gastroenterological endoscopy without migration of the visceral organ, and 4) puncture of the needle introducer of the PEG tube in the center of the fixations under repeated gastroenterological endoscopy 3 d after the fixation. She underwent P-V shunting under local anesthesia on the 28th day after placement of PEG and enteral nutrition. Her case shows that we can achieve proper enteral nutritional support even for patients with massive cirrhotic ascites.

    Ascitic feline coronavirus (FCoV) RNA was examined in 854 cats with suspected feline infectious peritonitis (FIP) by RT-PCR. The positivity was significantly higher in purebreds (62.2%) than in crossbreds (34.8%) (P<0.0001). Among purebreds, the positivities in the Norwegian forest cat (92.3%) and Scottish fold (77.6%) were significantly higher than the average of purebreds (P=0.0274 and 0.0251, respectively). The positivity was significantly higher in males (51.5%) than in females (35.7%) (P<0.0001), whereas no gender difference has generally been noted in FCoV antibody prevalence, indicating that FIP more frequently develops in males among FCoV-infected cats. Genotyping was performed for 377 gene-positive specimens. Type I (83.3%) was far more predominantly detected than type II (10.6%) (P<0.0001), similar to previous serological and genetic surveys.

    The antitumor activity of ethanol extract of Prosopis glandulosa Torr. (EPG) was evaluated against Ehrlich ascites carcinoma (EAC) tumor model in Swiss albino mice on dose dependent manner. The activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. Oral administration of EPG at the dose of 100, 200 and 400 mg/Kg, significantly (p < 0.001) increased the survival time and decreased the average body weight of the tumor bearing mice. After 14 days of inoculation, EPG was able to reverse the changes in the hematological parameters, protein and PCV consequent to tumor inoculation. Oral administration of EPG was effective in reducing solid tumor mass development induced by EAC cells. The results indicate that EPG possess significant antitumor activity on dose dependent manner.

    The attachment of allergised and non-allergised lymph-node cells from C57B1 mice to BP8 ascites tumour cells were compared in vitro in the presence of vaso-active agents and mediators of the inflammatory reaction. It was found that Priscol, noradrenaline, adrenaline, 5-HT and histamine caused some cell adherence, while bradykinin and lysolecithin caused a marked increase of adherence of the allergised lymph-node cells to the BP8 cells. Electrophoretic studies of BP8 cells in the presence of polyornithine showed an abolition of the anodic mobility. Theories of action of the various agents are discussed.

    1. Blood oxygen saturation (SaO) is a potential indicator trait for resistance to ascites in chickens. 2. The objective of the study was to investigate the genetic architecture of SaO in a meat-type chicken line reared in commercial conditions. 3. Data were collected over 15 generations of selection and were divided into two data sets on the basis of a change in recording age from 6 to 5 weeks of age, approximately halfway through the period. The resulting pedigrees comprised in excess of 90,000 birds each and, on average, 12% of these birds had SaO records. 4. Segregation analyses of SaO were carried out assuming a mixed inheritance model that included a major locus segregating in a polygenic background. 5. The analyses suggest that a major gene is involved in the genetic control of SaO in this line. The putative gene acts in a dominant fashion and has an additive effect of around 0.90 sigma(p), equivalent to a predicted difference in SaO between the two homozygous classes of more than 10%. The frequency of the allele that increases SaO changed from 0.53 to 0.65 from the first to the second set of data, consistent with selection on SaO scores. 6. Using estimated genotype probabilities at the putative major locus, we inferred that it acts in an overdominant fashion on body weight and fleshing score. If the low SaO allele leads to susceptibility to ascites, its combined effects are consistent with it being maintained in the population by a balance of natural selection on fitness nad artificial selection on growth and carcase traits. 7. Even with selection on both SaO and growth traits, the combined genotypic effects would make it difficult to remove the unfavourable low-SaO allele by means of traditional selection without the use of genetic markers.

    Background Marine environment is inestimable for their chemical and biological diversity and therefore is an extraordinary resource for the discovery of new anticancer drugs. Recent development in elucidation of the mechanism and therapeutic action of natural products helped to evaluate for their potential activity. Methods We evaluated Gracilaria edulis J. Ag (Brown algae), for its antitumor potential against the Ehrlich ascites tumor (EAT) in vivo and in vitro. Cytotoxicity evaluation of Ethanol Extract of Gracilaria edulis (EEGE) using EAT cells showed significant activity. In vitro studies indicated that EEGE cytotoxicity to EAT cells is mediated through its ability to produce reactive oxygen species (ROS) and therefore decreasing intracellular glutathione (GSH) levels may be attributed to oxidative stress. Results Apoptotic parameters including Annexin-V positive cells, increased levels of DNA fragmentation and increased caspase-2, caspase-3 and caspase-9 activities indicated the mechanism might be by inducing apoptosis. Intraperitoneally administration of EEGE to EAT-bearing mice helped to increase the lifespan of the animals significantly inhibited tumor growth and increased survival of mice. Extensive hematology, biochemistry and histopathological analysis of liver and kidney indicated that daily doses of EEGE up to 300 mg/kg for 35 days are well tolerated and did not cause hematotoxicity nor renal or hepatotoxicity. Conclusion Comprehensive antitumor analysis in animal model and in Ehrlich Ascites Tumor cells was done including biochemical, and pathological evaluations indicate antitumor activity of the extract and non toxic in vivo. It was evident that the mechanism explains the apoptotic activity of the algae extract. PMID:24274337

    Previously, it was demonstrated that acute (4 min) and chronic (12 d) occlusion of an extrapulmonary primary bronchus triggers pulmonary hypertension but not pulmonary hypertension syndrome (PHS, ascites) in broilers. The present study was conducted to determine whether a more prolonged period of bronchus occlusion causes PHS similar to that induced by clamping one pulmonary artery. Male and female broiler chicks, 14 to 18 d old, were anesthetized, the thoracic inlet was opened, and a silver clip was positioned to fully obstruct the left extrapulmonary primary bronchus (BRONCHUS CLAMP group) or the left pulmonary artery (PA-CLAMP group). Sham-operated chicks were anesthetized and the thoracic inlet was opened; however, neither the pulmonary artery nor the bronchus was clamped (SHAM group). An electrocardiogram (ECG) was obtained whenever clinical ascites became apparent in individual broilers, or prior to the final necropsy for broilers surviving to the end (Day 36) of the experiment. The right:total ventricular weight ratio (RV:TV) was evaluated as an index of pulmonary arterial pressure. Early post-surgical mortality (up to 21 d of age) was higher in the PA-CLAMP group (27% for males and females combined) than in the BRONCHUS CLAMP (10%) and SHAM (2%) groups. Cumulative ascites mortality (Days 22 to 36) also was higher in the PA-CLAMP group (86% for males, 77% for females) than in the BRONCHUS CLAMP (69% for males, 41% for females) and SHAM (23% for males, 0% for females) groups. Ascitic birds in all treatment groups had higher RV:TV ratios and more negative ECG Lead II S-wave amplitudes than nonascitic birds, reflecting the right ventricular hypertrophy and generalized ventricular dilation typically associated with PHS. These results demonstrate that unilateral bronchus occlusion is an effective experimental model for triggering ascites at a lower incidence than that obtained by occluding one pulmonary artery. Following the onset of pulmonary hypertension, the

    The development of ascites was investigated in broilers at low versus high altitudes, cold versus normal ambient temperatures (AT), and 3 feeding regimens. One-day-old chicks obtained at sea level were reared at high altitude (highA; 1,720 m; n = 576) with 2 AT treatments, low AT from 3 wk onward at highA (highA/cold) and normal AT from 3 wk onward at highA (highA/norm), or at sea level (normal AT from 3 wk onward at low altitude, lowA/norm; n = 540). Under highA/cold, AT ranged between 16 to 17 degrees C in the fourth week, 17 to 19 degrees C in the fifth week, and 19 to 21 degrees C thereafter. Under highA/norm and lowA/norm, AT was 24 degrees C in the fourth week and ranged between 22 to 24 degrees C thereafter. Broilers in each condition were divided into 3 groups: feed restriction (FR) from 7 to 14 d, FR from 7 to 21 d, and ad libitum (AL). Ascites mortality and related parameters were recorded. Low mortality (0.4%) occurred under lowA/norm conditions. Under highA/norm, mortality was lower in females (8.6%) than in males (13.8%) and was not affected by the feeding regimen. The highA/cold treatment resulted in higher mortality but only in males; it was 44.2% among highA/cold AL-fed males and only about 26% under the FR regimens, suggesting that FR helped some males to better acclimatize to the highA/cold environment and avoid ascites. However, mortality was only 13.3% in AL-fed males at highA/norm and FR did not further reduce the incidence of ascites under these conditions. Thus, avoiding low AT in the poultry house by slight heating was more effective than FR in reducing ascites mortality at highA. Compared with FR from 7 to 14 d, FR from 7 to 21 d did not further reduce mortality and reduced growth. At 47 d, the majority of surviving broilers at highA had high levels of hematocrit and right ventricle:total ventricle weight ratio (>0.29), but they were healthy and reached approximately the same BW as their counterparts at low altitude.

    We determined mRNA expression of genes of endothelin-1 (ET-1), and of the transforming growth factor beta ligands (TGFβ1, TGFβ2 and TGFβ3), their receptors (TβRI and TβRII) and their pseudoreceptor BAMBI in the heart of broilers raised under cold temperature conditions and affected by pulmonary hypertension. Gene expression was determined by RT-qPCR in right myocardial ventricle samples from 4-week-old chickens (n = 48) raised either under normal (control) or cold temperature conditions (22 °C versus 14 °C). We do not find differences among healthy birds, birds with cardiac failure and ascitic birds in the mRNA levels of TGFβ2, TGFβ3 and BAMBI. In the control group, ET-1 mRNA level was increased in the ascitic birds as compared with healthy birds and birds with cardiac failure (p < 0.05) whereas in the cold treated group, no increase was observed (p > 0.05); yet, ascitic birds in the cold group showed lower mean than ascitic birds in the control group (p < 0.05). TβRII mRNA expression was higher in ascitic than in healthy birds (p < 0.05) in both control and cold treated groups; however, in the ascitic birds of the cold treated group TβRII expression was lower than in ascitic birds from the control group (p < 0.05). Thus, the higher ET-1 and TβRII levels observed in ascitic birds seem to be attenuated by cold.

    Aim: This study investigated the immunomodulatory and anti-tumor effects of Nigella glandulifera Freyn and Sint seeds (NGS) on Ehrlich ascites carcinoma in a mouse model. Materials and Methods: Kunming mice with transplanted Ehrlich ascites tumor cells (EAC) were treated with NGS by oral administration. On the 11th day after the EAC implant, mouse thymus, liver, spleen and kidney tumors were removed for histopathological analysis. Blood samples were taken for hematological and biochemical analyses. Results: The results indicate that NGS treatment leads to an increase in TNF-α, IL-1β, and IL-2 blood serum levels. Absence of viable EAC and presence of necrotic cells were observed in the tumor tissue of the NGS-treated animals. Conclusions: The study results indicated that a water extract of NGS had the highest anti-tumor effect. Moreover, NGS treatment also showed an increase in the immune system activity. PMID:23929999

The isolated particles show a high specific activity for aryl sulfatase, representing an 80–90-fold purification over the homogenate, and a 15–18% yield of the total enzyme activity. Mitochondrial and microsomal marker enzymes are present in negligible amounts (0.2% of the activity of the homogenate). The biochemical evidence for a rather high degree of homogeneity of the fraction is supported by the electron microscopic examination of the purified lysosomes. The intracellular localizations of N-acetyl-β-glucosaminidase, NADH-cytochrome c reductase and NADPH-cytochrome c reductase in Ehrlich ascites cells are also reported, the first two being present in highest concentration in the combined mitochondrial-lysosomal fraction and the third in the microsomal fraction.

Mitochondrial and microsomal marker enzymes are present in negligible amounts (0.2% of the activity of the homogenate). The biochemical evidence for a rather high degree of homogeneity of the fraction is supported by the electron microscopic examination of the purified lysosomes. The intracellular localizations of N-acetyl-beta-glucosaminidase, NADH-cytochrome c reductase and NADPH-cytochrome c reductase in Ehrlich ascites cells are also reported, the first two being present in highest concentration in the combined mitochondrial-lysosomal fraction and the third in the microsomal fraction.

    Bleeding from gastro-esophageal varices can often present as the first decompensating event in patients with cirrhosis. This can be a potentially life threatening event associated with a 15%-20% early mortality. We present a rare case of new onset ascites due to intra-abdominal hemorrhage from ruptured mesenteric varices; in a 37 years old male with newly diagnosed nonalcoholic steatohepatitis induced cirrhosis as the first decompensating event. The patient was successfully resuscitated with emergent evacuation of ascites for diagnosis, identification and control of bleeding mesenteric varices and eventually orthotopic liver transplantation with successful outcome. Various clinical presentations, available treatment options and outcomes of ectopic variceal bleeding are discussed in this report.

    Malignant ascites is an abnormal accumulation of fluid in the peritoneal cavity of patients with intraperitoneal cancer dissemination. This clinical condition could represent the terminal evolution of a lethal disease and could influence the prognosis, severely impairing the patients' quality of life. Treatment options include a multitude of different procedures with limited efficacy and some degree of risk; diuretics, paracentesis, peritoneo-venous shunts and intraperitoneal biologic agents like anti-VEGF molecules, metalloproteinase inhibitors and immunomodulators are included. None of these approaches have been established as a standard of care because of their low efficacy or severe side effects. The last two decades saw the emergence of cytoreductive surgery with hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) as a viable therapeutic approach resulting in an effective cure against refractory malignant ascites. The following describes our experiences with 3 cases together with a literature review.

    PurposeTo investigate the efficacy and safety of the use of transjugular intrahepatic portosystemic shunt (TIPS) creation to treat cirrhosis-related chylous collections (chylothorax and chylous ascites).MethodsWe retrospectively reviewed data from four patients treated for refractory cirrhosis-related chylous collections with TIPS at our institution over an 8 year period.ResultsOne patient had chylothorax, and three patients had concomitant chylothorax and chylous ascites. There were no major complications, and the only procedure-related complications occurred in two patients who had mild, treatable hepatic encephalopathy. All patients had improvement as defined by decreased need for thoracentesis or paracentesis, with postprocedure follow-up ranging from 19 to 491 days.ConclusionTIPS is a safe procedure that is effective in the treatment of cirrhosis-related chylous collections.

    Ascites syndrome, also known as pulmonary hypertension syndrome (PHS), is a common metabolic disorder in rapidly growing meat-type chickens. Environmental factors, such as cold, altitude, and diet, play significant roles in development of the disease, but there is also an important genetic component to PHS susceptibility. The human disease familial primary pulmonary hypertension (FPPH) is similar to PHS in broilers both genetically and physiologically. Several recent studies have shown that mutations in the bone morphogenetic protein receptor type II (BMPR2) gene are a cause of FPPH in humans. To determine whether mutations in the chicken BMPR2 gene play a similar role in PHS susceptibility, BMPR-II mRNA from ascitic and nonascitic commercial broilers were sequenced and compared with the published Leghorn chicken BMPR-II mRNA sequence. Fourteen single nucleotide polymorphisms (SNP) were identified in the commercial broiler BMPR-II mRNA. No mutations unique to ascites-susceptible broilers were present in the coding, 5' untranslated or 3' untranslated regions of BMPR-II mRNA. The twelve SNP present within the coding region of BMPR-II mRNA were synonymous substitutions and did not alter the BMPR-II protein sequence. In addition, analysis of BMPR2 gene expression by reverse transcriptase-PCR indicated that there were no differences in BMPR-II mRNA levels in ascitic and nonascitic birds. Therefore, it appears unlikely that mutations in the BMPR2 gene were responsible for susceptibility to PHS in these commercial broilers.

    Three experiments were conducted, from January until September 2001, to estimate the optimized age to apply feed restriction to control mortality from ascites, with no negative effects on production and carcass characteristics of broilers. For each experiment, 1,200 1-d-old mixed Ross x Peterson chicks were reared in floor pens (50 chicks in each) and fed commercial feed. Feed restriction was applied for 8 h/d for 14 d at 21 or 28 d of age in experiment 1, 14 or 21 d in experiment 2, and 7 or 14 d in experiment 3. In experiments 2 and 3, a microelement supplement (without or with) was tested; the control groups received feed ad libitum and no supplement. Body weight gain, feed conversion, total mortality, and mortality from ascites, leg problems, and carcass characteristics were considered at the end of each experiment. The data were analyzed as a completely randomized design, or as a 2 x 2 factorial to estimate main and interaction effects (experiments 2 and 3). Additional analyses, including the control, were done; means comparisons were by orthogonal contrasts. The production and carcass characteristics of the restricted groups were lower than the control but were not statistically different in experiments 2 and 3, although the optimized age for feed restriction was at 7 d. Total mortality and mortality from ascites decreased by restriction, but leg problems increased without supplement. The results indicated that quantitative feed restriction and microelement supplementation at 7 d of age reduced mortality from ascites and leg problems and permitted compensatory growth sufficient to equal the production characteristics of the control group at 49 d of age. However, it is necessary to determine the specific microelements to be supplemented and to estimate the effects of season and genetic line.

    The effect of feed restriction and the application of canola oil to broiler straw litter to contain respirable dust on growth performance, carcass traits, and the incidence of ascites was evaluated with 800 male broilers studied in two 6-wk periods. Two pens of birds were feed restricted. Two pens of birds received feed ad libitum for the 6-wk trial. One restricted and one ad libitum pen received biweekly addition of canola oil to the litter. At 6 wk of age, 30 birds from each pen were killed for determination of breast muscle, fat pad, and heart weights. All birds were scored for the incidence of ascites at processing. A cross sectional image of each heart was digitally recorded and, using image analysis, the right ventricular area (RVA), left ventricular area (LVA), and total heart area (HA) were determined. The right ventricular wall was removed and its weight was expressed as a percentage of total heart weight (PRVW). The 40-d BW was significantly greater in the ad libitum birds (2.07 kg) than in the feed-restricted birds (1.86 kg). The right ventricular weight (RVW) (1.69 and 1.92 g) and the RVA (0.35 and 0.40 cm2) were also significantly different between the two feeding treatments. The ascites score was significantly correlated to the RVW (r = 0.50) and RVA (r = 0.52). The RVA was also correlated to the RVW (r = 0.63). Oiling the litter did not result in differences in carcass characteristics. Litter oiling significantly reduced the RVA of the ad libitum birds (0.36 cm2) compared to the ad libitum birds that did not have oiled litter (0.44 cm2). Feed restriction reduced the incidence of ascites, but also reduced gain. Litter oiling in the feed-restricted groups reduced the RVA, but did not reduce mortality.

    Ascites syndrome (AS) is a major cause of economic losses to the broiler industry. The tendency of broilers to develop AS was found to be heritable, suggesting that selective breeding could provide a solution to this problem. To further elucidate the genetic control of AS, AS-susceptible (AS-S) and AS-resistant (AS-R) lines were established by 3 cycles of divergent selection on pedigree data of AS mortality under AS-inducing conditions. The rapid divergence between the lines suggested the involvement of a major gene with dominance for AS resistance. It was hypothesized that the difference between the lines is controlled by a single dominant gene, denoted A, with AA (and some Aa) individuals in the AS-R line, and aa individuals in the AS-S line. The current study was designed to test this hypothesis by test-crossing heterozygous (Aa) sires from the AS-R line and F(1) from the AS-R x AS-S cross, with recessive homozygous (aa) dams from the AS-S line. A ratio of 1:1 was expected between progeny with AS vs. healthy progeny when reared under AS-inducing conditions. Test-cross progeny of 5 sires from the AS-R line segregated 1:1, indicating that these sires were heterozygous (Aa) in the suggested major gene and thus supporting the hypothesis of a single major gene with dominance of AS resistance. There was segregation among test-cross progeny of 8 F(1) sires, but with a 3:1 ratio of AS progeny to healthy progeny. The 3:1 ratio is expected if the F(1) sires are heterozygous (AaBb) with complementary interaction between the dominant alleles in 2 unlinked major genes. The segregation among test-cross progeny of the 9 heterozygous AS-R sires could also be explained by the same model. These results suggested that 2 major genes are responsible for the difference between the AS-R and AS-S lines. Resource populations derived from these lines will facilitate an efficient genomic search for these 2 genes. Once the alleles of these genes are identified and genotyping tests are

    1,4,6,8-Tetramethyl-2H-furo[2,3h]quinolin-2-one (FQ) belongs to a series of furocoumarin isosters, designed to obtain new drugs for photochemotherapy. The objective of this study was to characterize the disposition of orally administered 3H-FQ in normal and ascitic tumor bearing mice and to evaluate the influence of UVA irradiation in control mice. This compound was rapidly absorbed and its decay in serum was biphasic. Binding to serum proteins, which was maximum at 30 min (74 %), time-dependently declined. FQ was distributed to all the studied tissues, primarily to the liver and kidneys. The administered radioactivity was excreted mostly in the urine (43 %) and was associated with polar metabolites. The unchanged compound was not present to any detectable extent in the urine. Elimination in the faeces, that may include FQ not absorbed, was low (14 % of administered radioactivity), emphasizing the quantitatively efficient gastrointestinal absorption of the drug. UVA irradiation of FQ-treated mice for 2 h caused a significant increase in radioactivity measured in serum as well as in the liver. In mice bearing Ehrlich ascitic tumor, serum and tissue concentrations were lower than in control animals, possibly due to the larger volume of body fluids (10+/-4 ml of ascitic fluid) available for drug distribution.

    Ascites syndrome (AS) is manifested in flocks of contemporary broilers that are allowed to fully manifest their genetic potential for rapid growth. After successful selection, a pair of divergent lines was established, AS-susceptible (AS-S) and AS-resistant (AS-R). These lines facilitate comparisons between genetically resistant and susceptible healthy young broilers when reared under standard brooding conditions (SBC). The aim of the present study was to look for predictive indicators for AS susceptibility by comparing relevant physiological parameters in the AS-S and AS-R lines under SBC and after exposure to extreme ascites-inducing conditions (AIC). In this design, a trait differing significantly between the 2 lines under SBC is expected to be a reliable indicator for selection against AS susceptibility in breeding stocks when reared under noninducing conditions. Males from the AS-S and AS-R lines were reared together under SBC to 19 d of age, then under the AIC protocol. Cumulative incidence of AS mortality was 93.2% in the AS-S line and only 9% in the AS-R line, confirming the genetic divergence between the lines. Exposure to AIC enhanced the imbalance between oxygen demands and supply in the AS-S birds and induced differences in blood parameter level between the 2 lines. The AS-S birds exhibited elevated hematocrit and red blood cell counts and a decline in oxygen saturation in the arterial blood. No difference in hemoglobin concentration was found, but calculation of hemoglobin content per 1,000 red blood cells revealed a significant reduction in hemoglobin content in the AS-S birds. Under SBC, there were no significant differences between the lines for hematocrit, red blood cell count, hemoglobin concentration, hemoglobin count per 1,000 red cells, and blood oxygen saturation. However, heart rate during the first week of life was significantly higher in the AS-S birds than in the AS-R birds on d 1 and 7, suggesting that high heart rate may potentially

    1. Three experiments were conducted using a low temperature model to induce pulmonary hypertension (PH) and ascites in broiler chickens. Diets containing 25 g or 50 g flax oil/kg food and control diets with an equivalent amount of animal/vegetable (A/V) blend oil, with and without supplemental antioxidants (vitamin C and vitamin E) were used. The amount of PH was assessed by the ratio of right ventricle weight to total ventricle weight (RV/TV ratio). Birds were considered to suffer from pulmonary hypertension syndrome (PHS) if the RV/TV ratio was greater than 0.299. 2. In experiment 1, the test diets contained 50 g oil/kg food and were given during the grower period only. Birds fed on the flax oil diet tended to have a lower incidence of PHS, ascites and lower RV/TV ratios than birds fed on the control diet. However, when the flax oil diet was supplemented with antioxidants, the incidence of ascites, PHS, haematocrit and whole blood and plasma viscosity increased compared with birds fed on the flax oil diet without antioxidants. These effects were not seen in experiment 2, when the test diets containing 30 g oil/kg food (25 g flax oil plus 5 g A/V blend oil/kg food compared to 30 g A/V blend oil/kg food) were given during the grower period. However, in experiment 3, when the test diets containing 30 g oil/kg food were given from day 1 to week 8, birds fed on the control diet supplemented with antioxidants had a higher incidence of PHS than those fed on the control diet alone. 3. In all 3 experiments, there was no significant effect of dietary fat source or supplemental antioxidants on total food intake or food conversion. 4. We conclude that diets containing 50 g flax oil/kg food tend to reduce the incidence of PHS and ascites in broilers using a low temperature model but the results were not statistically significant. In some cases, supplementing diets with a combination of vitamin E and vitamin C increased the incidence of ascites and PHS.

    The study was conducted to determine the effects of dietary L-carnitine and coenzyme Q10 (CoQ10) supplementation on growth performance and ascites mortality of broilers. A 3 x 3 factorial arrangement was employed with three levels (0, 75 and 150 mg/kg) of L-carnitine and three levels of CoQ10 (0, 20 and 40 mg/kg) supplementation during the experiment. Five hundred and forty one-day-old Arbor Acre male broiler chicks were randomly allocated into nine groups with six replicates each. All birds were fed with the basal diets from day 1 to 7 and changed to the experimental diets from day 8. During day 15 to 21 all the birds were exposed to low ambient temperature (15-18 degrees C) to induce ascites. The results showed that under this condition, growth performance of broilers were not significantly affected by CoQ10 or L-carnitine + CoQ10 supplementation during week 0-3 and 0-6, but body weight gain (BWG) of broilers was significantly reduced by 150 mg/ kg L-carnitine during week 0-6. Packed cell volume (PCV) of broilers was significantly decreased by L-carnitine and L-carnitine + CoQ10 supplementation (P < 0.05). Erythrocyte osmotic fragility (EOF), ascites heart index (AHI) and ascites mortality of broilers were significantly decreased by L-carnitine, CoQ10 and L-carnitine + CoQ10 supplementation. Though no significant changes were observed in total antioxidative capability (T-AOC), total superoxide dismutase (T-SOD) was increased by L-carnitine, CoQ10 and L-carnitine + CoQ10 supplementation (P < 0.05). Malonaldehyde (MDA) content was significantly decreased by CoQ10 and L-carnitine + CoQ10 supplementation. The results indicate that dietary L-carnitine and CoQ10 supplementation reduce ascites mortality of broilers; the reason may be partially associated with their antioxidative effects.

    OBJECTIVE. This single-center study evaluated the use of expanded polytetrafluoroethylene (ePTFE)-covered stent-grafts for transjugular intrahepatic portosystemic shunt (TIPS) placement to manage portal hypertension-related refractory ascites. MATERIALS AND METHODS. One hundred patients at a single tertiary care center in a major metropolitan hospital underwent TIPS placement with an ePTFE-covered stent-graft (Viatorr TIPS Endoprosthesis). Patients with portal hypertension-related ascites and preexisting hepatocellular carcinoma or liver transplant were excluded from the analysis. Records were reviewed for demographic characteristics, technical success of the TIPS procedures, and stent follow-up findings. Clinical results were assessed at 90- and 180-day intervals. RESULTS. Immediate technical success of the TIPS procedure was 100%. Of the 61 patients with documented follow-up, 55 (90.2%) had a partial or complete ascites response to TIPS creation. Of these 55 patients, nine experienced severe encephalopathy. Six of 61 patients (9.8%) did not experience a significant ascites response. Overall survival was 78.7% at 365-day follow-up. The 365-day survival was 84.2% for patients with a model for end-stage liver disease (MELD) score of less than 15, 67.0% for those with a score of 15-18, and 53.8% for those with a score of greater than 18 (p = 0.01). For patients with a MELD score of less than 18, the 365-day survival was 88.0% for those with an albumin value of 3 mg/dL or greater and 72.8% for those with an albumin value of less than 3 mg/dL (p = 0.04). CONCLUSION. TIPS placement using an ePTFE-covered stent-graft is an efficacious therapy for refractory ascites. Patients with preserved liver function-characterized by a MELD score of less than 15 or a MELD score of less than 18 and an albumin value of 3 mg/dL or greater-experience the greatest survival benefit.

    Thioredoxin reductase (TrxR) is a target for cancer therapy and the anticancer mechanism of cisplatin involves TrxR inhibition. We hypothesize that the anticancer drug nedaplatin (NDP), an analogue of cisplatin and a second-generation platinum complex, also targets TrxR. Furthermore, we investigate whether the therapeutic efficacy of NDP can be enhanced by simultaneous modulation of 1) TrxR, via NDP, and 2) glutathione (GSH), via the GSH synthesis inhibitor buthionine sulfoximine (BSO). Mice bearing ascitic hepatoma 22 (H22) cells were treated with NDP alone or NDP plus BSO. TrxR activity of H22 cells was inhibited by NDP in a dose-dependent manner. A high correlation between the inhibition of TrxR activity at 6 h and the inhibition of ascitic fluid volume at 72 h was established (r = 0.978, p < 0.01). As an adaptive response, the viable ascitic cancer cells after NDP treatment displayed an enlarged cell phenotype, assembled with several-fold more antioxidant enzymes and GSH-predominant non-protein free thiols. This adaptive response was largely eliminated when BSO was co-administered with NDP, leading to the decimation of the H22 cell population without enhancing renal toxicity, since at this dose, NDP did not inhibit renal TrxR activity. In conclusion, the pharmacological effect of NDP involves TrxR inhibition, and the adaptive response of NDP-treated ascitic H22 cells can be efficiently counteracted by BSO. Simultaneous modulation of TrxR and GSH on ascitic H22 cells using NDP plus BSO greatly enhances therapeutic efficacy as compared with the single modulation of TrxR using NDP alone. -- Highlights: ► Nedaplatin at a pharmacological dose inhibits TrxR in cancer cells but not in kidney. ► The nedaplatin-treated cancer cells exhibit adaptive response. ► Buthionine sulfoximine inhibits glutathione in both cancer cells and kidney. ► Buthionine sulfoximine counteracts the adaptive response to the nedaplatin treatment. ► Buthionine sulfoximine does not

    Objective To evaluate the antitumor activity of Manilkara zapota (M. zapota) L. stem bark against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Methods The in vivo antitumour activity of the ethyl acetate extract of stem bark of M. zapota L. (EASM) was evaluated at 50, 100 and 200 mg/kg bw against EAC using mean survival time. After administration of the extract of M. zapota, viable EAC cell count and body weight in the EAC tumour hosts were observed. The animal was also observed for improvement in the haematological parameters (e.g., heamoglobin content, red and white blood cells count and differential cell count) after EASM treatment. Results Intraperitoneal administration of EASM reduced viable EAC cells, increased the survival time, and restored altered haematological parameters. Significant efficacy was observed for EASM at 100 mg/kg dose (P<0.05). Conclusions It can be concluded that the ethyl acetate extract of stem bark of M. zapota L. possesses significant antitumour activity. PMID:23569811

    (1) Genetic parameters for the sudden death syndrome (SDS) were estimated in meat-type chickens. Data were collected over 11 generations of selection for body weight within two distinct breeds (Cornish and White Rock). (2) The animal model was used exclusively with linear methods (LM) to estimate genetic parameters. Heritability (h2) of SDS on the liability scale was 0.30 +/- 0.002 and 0.25 +/- 0.002 in the Cornish and White Rock breeds, respectively. (3) A positive genetic correlation (r(g)) with ascites (AS) was determined (approximately 0.3 +/- 0.006). However, it was not possible to estimate the rg of SDS with body weight because of the low prevalence of the defect trait studied (1.8% in the Cornish and 1-5% in the White Rock). (4) Heritability of SDS calculated using male records only was 0.45 +/- 0.009 and 0.35 +/- 0.009, and r(g) with body weight was 0.30 +/- 0.010 and 0.27 +/- 0.009, in the Cornish and White Rock breeds, respectively.

    The aim of the present investigation was to evaluate Zingiber officinale paste against Dalton's lymphoma ascites (DLA)-induced tumours in Swiss albino mice. Experimental animals received Z. officinale paste (low dose 100 mg/kg bw and high dose 500 mg/kg bw) orally for eight alternative days. Treatment with Z. officinale paste showed significant increase in haemoglobin level and decrease in aspartate amino transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transferase (γ-GT) level. Z. officinale paste reduced the inflammatory mediators and cytokine levels, such as inducible nitric oxide (iNOS), tumour necrosis factor level (TNF-α) and interleukin-1β (IL-1β). Treatment with Z. officinale paste also significantly increased the antioxidant enzyme level, such as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and glutathione transferase (GST), and decreased the lipid peroxidation. Treatment also increased the vitamin C and E levels in treated animals compared with the DLA-bearing host. Histopathological studies also confirmed the protective influence of Z. officinale paste against DLA. The present study suggested that Z. officinale paste could be used as natural spice and a potent antitumour agent.

    Several aspects of the interaction of various lectins with the surface of Ehrlich ascites carcinoma cells are described. The order of agglutinating activity for various lectins is Ricinus communis greater than wheat germ greater than or equal to concanavalin A greater than or equal to soybean greater than Limulus polyphemus. No agglutination was noted for Ulex europaeus. Using 125I-labeled lectins it was determined that there are 1.6 and 7 times as many Ricinus communis lectin binding sites for concanavalin A and soybean lectins. Sodium deoxycholate-solubilized plasma membrane material was subjected to lectin affinity chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The lectin receptors of the plasma membrane appeared to be heterogeneous and some qualitative differences could be discerned among the electrophoretically analyzed material, which bound to and was specifically eluted from the various lectin affinity columns. The characteristics of elution of bound material from individual lectin columns indicated secondary hydrophobic interactions between concanavalin A or wheat germ agglutinin and their respective lectin receptor molecules.

    The assumption of upright posture by patients with liver cirrhosis leads to striking activation of adrenergic and renin-angiotensin systems. The tilting-induced modifications in renal function of eight healthy controls and 14 untreated patients with liver cirrhosis and ascites were related to plasma concentrations of noradrenaline, renin activity and aldosterone. All patients had preserved renal blood perfusion. All parameters were evaluated during bed rest for two hours and in the sitting posture for one hour. Basal plasma renin activity (0.1 greater than p greater than 0.05), aldosterone and noradrenaline concentrations (p less than or equal to 0.01) were raised in cirrhotics. The renal function tests (creatinine clearance, filtered sodium, tubular rejection fraction, urinary sodium excretion) were significantly reduced in cirrhosis. Under basal conditions, in cirrhotic patients tubular rejection fraction and urinary sodium excretion were inversely related to both noradrenaline and aldosterone concentrations. After tilting, the noradrenaline and aldosterone integrated outputs (sigma delta) were significantly greater in cirrhosis. All renal function tests significantly decreased in cirrhotics, whereas creatinine clearance only significantly decreased in controls. Patient's tubular rejection fraction of sodium and sodium excretion were related to sigma delta aldosteronaemia (r = -0.72; p less than 0.01), but no longer to sigma delta plasma noradrenaline.

Reserpine remarkably enhanced the cytotoxic effect of 1-(gamma-chloropropyl)-2-chloromethylpiperidine hydrobromide (CAP-2) both on AH13 and AH44 cells. In the in vivo combined experiments, reserpine also synergistically enhanced the life-prolonging effect of CAP-2 on AH13-bearing rats and, although CAP-2 was not potent on the prolongation of life span of AH44-bearing rats and reserpine was also ineffective at the doses examined, the life span of tumor-bearing rats receiving the combined administration was apparently prolonged compared with control groups. Thus, there was a parallelism between in vitro and in vivo experiments. These findings suggested that the antitumor-enhancing effect of reserpine might be due to the direct action on the tumor cells, and a possible mechanism that reserpine inhibited the DNA damage-repairing activity of the cells was contradictory. Other mechanisms are also discussed.

    The effect of radiation on tumor tissue can be optimized by adding radiosensitizing agents, in order to achieve a greater degree of tumor damage than expected from the use of either treatment alone. The ethanolic extract of Aphanamixis polystachya (APE) was tested in Swiss albino mice transplanted with Ehrlich ascites carcinoma (EAC) and exposed to various doses of gamma-radiation. EAC mice received 0, 10, 25, 50, 75, 100, 150 or 200 mg/kg body wt APE before exposure to 6 Gy gamma-radiation followed by once daily administration for another 8 consecutive days post-irradiation. The optimum radiosensitizing dose was found to be 50 mg/kg APE that was further tested in EAC mice exposed to 0, 1, 2, 4, 6 or 8 Gy hemi body gamma-radiation. The best effect of APE and radiation was observed for 6 Gy gamma-radiation. The splitting of 50 mg into two equal fractions of 25 mg and administering the split dose with a gap of 8 h on 1, 3, 5, 7 or 9 d of tumor inoculation resulted in an increased survival even when the drug was administered at late stages (day 5) of tumor development. The APE treatment before irradiation elevated lipid peroxidation followed by a reduction in the glutathione contents. Treatment of tumor bearing mice with APE before irradiation further reduced the activities of various antioxidant enzymes like glutathione peroxidase, glutathione-s-transferase, superoxide dismutase and catalase at different post last drug administration (PLDA) times.

    Tumor plasminogen activator (PA) has been alleged to play a role in the growth and metastasis of tumors. Before such a role can be realized, PA first must be released from tumor cells. Having determined intra- and extracellular PA and PA-inhibitor activities in an experimental pancreatic ascites tumor grown in hamsters, the release of PA from these cells was investigated. No PA activity was detected in the suspension medium of freshly isolated tumor cells; inclusion of plasminogen, fibrinogen, or collagen in the medium yielded similar negative results. On the other hand, PA activity was demonstrated to be released in a time-dependent manner from these tumor cells embedded in fibrin clots. Plasminogen activator activity also was not found in the suspension medium of frozen-thawed tumor cells, despite the fact that most of them had breaks on their cell membrane. Unlike freshly isolated tumor cells, PA was not released from frozen-thawed cells embedded in fibrin clots. Full PA activity was demonstrated in frozen-thawed cells treated with Triton X-100, however. Frozen-thawed cells exhibited signs of severe damage, and more than 80% of them failed to exclude trypan blue. Obviously PA is released from viable tumor cells embedded in fibrin clots but not suspended in artificial medium. The PA-release mechanism, not PA itself, is destroyed in cells rendered nonviable by freeze thawing. Images Figure 1 Figure 5 Figure 6 Figure 7 PMID:1902626

    Bi-212 is an alpha-emitting radionuclide being investigated as a therapeutic agent in the intraperitoneal treatment of micrometastatic ovarian carcinoma. In evaluating a new therapeutic modality, cell-survival studies are often used as a means of quantifying the biological effects of radiation. In this analysis, Ehrlich ascites cells were irradiated under conditions similar to therapy in various concentrations of Bi-212. Immediately following irradiation, a cell survival assay was performed in which cells were plated and colonies were counted after 10--14 days. Both a macrodosimetric and a microdosimetric approach were used in analyzing these data. These models used as input the fraction of activity within the cell and in solution, the distribution of cell sizes, and the variation of LET along individual alpha-particle tracks. The results indicate that the energy deposited within the nucleus varies significantly among individual cells. There is a small fraction of cell nuclei which receive no hits, while the remaining cells receive energy depositions which can differ significantly from the mean value. These dosimetric parameters are correlated with measured cell survival and will be a useful predictor of outcome for therapeutic doses.

    1. An enzyme has been partially purified from Ehrlich ascites tumour cells which specifically hydrolyses dinucleosidetetraphosphates, with Km values of around 2 microM. The products of the hydrolysis are the corresponding nucleoside tri- and monophosphates. Dinucleoside Tri- and diphosphates were not substrates of the reaction. 2. The enzyme requires Mg2+ or Mn2+, is maximally active at a pH value of approx. 7.5 and has a mol, wt of 19,800 as estimated by filtration on Sephadex G-75. Nucleoside mono-, di- and triphosphates were competitive inhibitors of the reaction with Ki values in the 0.1 mM range. 3. Particularly relevant is the inhibition of this enzyme by adenosine and guanosine 5'tetraphosphates. In the course of this investigation, the presence of uridine 5'-tetraphosphate was detected in a commercial preparation of UTP. Adenosine, guanosine and uridine 5'-tetraphosphates were very strong inhibitors of the reaction with Ki values in the nM range.

    Ascites or pulmonary hypertension syndrome is a metabolic disorder in broilers. Male broilers have a higher BW and are therefore expected to be more prone to developing ascites than females. As genetic parameters might be affected by the ascites incidence, genetic parameters might differ between male and female broilers. The aims of this study were to estimate the heritability for the ratio of right ventricular weight to total ventricular weight (RATIO) and BW in male and female broilers, the genetic correlation between RATIO and BW separately for male and female broilers, and the genetic correlations between BW for ascitic and nonascitic broilers. Data were available from 7,856 broilers (3,819 males and 4,037 females). The broilers in the experiment were kept under a cold temperature regimen and increased CO(2) levels. In this study, we showed that the incidence of ascites is higher in male than in female broilers. Heritability estimates for BW at 7 wk of age were higher for male (0.22) than for female (0.17) broilers, and for RATIO heritability, estimates were higher for female (0.44) than for male (0.32) broilers. The genetic correlations between RATIO and BW measured at different ages changed from slightly positive at 2 wk of age to moderately negative at 7 wk. The change in genetic correlation was more extreme for male (from 0.01 to -0.62) than for female (from 0.13 to -0.24) broilers. The difference in ascites incidence between male and female broilers is the most likely reason for the difference in genetic correlations. The genetic correlation between BW traits measured in broilers with fluid in the abdomen and without fluid in the abdomen decreased from 0.91 at 2 wk to 0.69 at 7 wk. We conclude that under circumstances with ascites, data from male and female broilers should be analyzed separately.

    Objective To evaluate risk factors for massive lymphatic ascites after laparoscopic retroperitoneal lymphadenectomy in gynecologic cancer and the feasibility of treatments using intranodal lymphangiography (INLAG) with glue embolization. Methods A retrospective analysis of 234 patients with gynecologic cancer who received laparoscopic retroperitonal lymphadenectomy between April 2006 and November 2015 was done. In June 2014, INLAG with glue embolization was initiated to manage massive lymphatic ascites. All possible clinicopathologic factors related to massive lymphatic ascites were determined in the pre-INLAG group (n=163). Clinical courses between pre-INLAG group and post-INLAG group (n=71) were compared. Results In the pre-INLAG group (n=163), four patients (2.5%) developed massive lymphatic ascites postoperatively. Postoperative lymphatic ascites was associated with liver cirrhosis (three cirrhotic patients, p<0.001). In the post-INLAG group, one patient with massive lymphatic ascites had a congestive heart failure and first received INLAG with glue embolization. She had pelvic drain removed within 7 days after INLAG. The mean duration of pelvic drain and hospital stay decreased after the introduction of INLAG (13.2 days vs. 10.9 days, p=0.001; 15.2 days vs. 12.6 days, p=0.001). There was no evidence of recurrence after this procedure. Conclusion Underlying medical conditions related to the reduced effective circulating volume, such as liver cirrhosis and heart failure, may be associated with massive lymphatic ascites after retroperitoneal lymphadenectomy. INLAG with glue embolization can be an alternative treatment options to treat leaking lymphatic channels in patients with massive lymphatic leakage. PMID:27171674

    Analysis of ascitic fluid should help to identify and characterize malignant cells in gastrointestinal cancer. However, despite a high specificity, the sensitivity of traditional ascitic fluid cytology remains insufficient, at around 60%. Since 2004 the CellSearch ® technology has shown its advantages in the detection of circulating tumor cells (CTCs) in peripheral blood, which can perform an accurate diagnosis and molecular analysis at the same time. To our knowledge, no previous study has explored the potential utility of this technology for the detection and quantification of tumor cells in ascitic fluid samples. Herein we report a case of metastatic esophageal adenocarcinoma in a 70-year-old man presenting with dysphagia and a large amount of fluid in the peritoneal cavity. Analysis of a peripheral blood sample and ascites sample with the CellSearch ® technology both revealed the presence of putative tumor cells that were positive for epithelial cell adhesion molecule (EpCAM) and cytokeratin (CK) expression. This study confirmed the hematogenous dissemination of esophageal cancer by the detection of circulating tumor cells in the peripheral blood, and is the first to demonstrate that tumor cells can be identified in ascitic fluid by using CellSearch ® technology.

    1. Male broilers of 5 genetic stocks (A, B, C, D, E) selected in different ways for fast growth and low food conversion ratio (FCR) and differing in ascites sensitivity were subjected to 2 different ambient temperature step down regimens: high temperature (HT: 33 to 20 degrees C over 33 d) and low temperature (LT: 30 to 15 degrees C over 17 d). 2. Ascites incidence was recorded daily. Food intake and body weight gain were measured weekly and FCR was calculated. Heat production (Hp) was calculated using the comparative slaughter method. At 28 d venous samples were taken for blood gas analysis and haematocrit and relative heart, lung and liver weights were recorded. 3. Populations A and C showed the highest growth rates combined with a low FCR and a higher ascites incidence. A low FCR in these stocks was attributable to low values for Hp. These stocks also had low PO2 and high pCO2 in venous blood at low ambient temperature compared with other stocks. Stock B, which exhibited the slowest growth rate and the highest FCR, was not susceptible to ascites and showed higher Hp and PO2 and pCO2 at low ambient temperature. Populations D and E were intermediate for almost all variables. Heart and lung weights were both increased at LT, while liver weight did not differ between temperature regimes. 4. Our results show that a high haematocrit is not necessarily linked with an increased susceptibility to ascites.

    To examine whether an angiotensin converting enzyme (ACE) inhibitor, benazepril, can be transformed to the active metabolite, benazeprilat, by severely injured liver of dogs with ascitic heartworm disease, benazepril hydrochloride was administered orally to dogs once daily for 7 consecutive days at a dose rate of 0.29 mg/kg to 0.63 mg/kg of body weight, and plasma benazepril and benazeprilat concentrations were determined on the 1st and 7th administration days. In 7 dogs with ascitic pulmonary heartworm disease, plasma benazeprilat concentrations tended to be higher than in 7 control dogs both on the 1st and 7th administration days. The peak concentration and area under the concentration-time curve tended to be greater in dogs of the ascites group than in control dogs, but the statistics could not detect significant differences in the time to peak concentration and t(1/2) between the control and ascites groups. Plasma ACE activities decreased after administration of benazepril. In dogs with ascitic heartworm disease, benazepril was readily transformed to benazeprilat by the liver, and was effective for suppression of plasma ACE activity.

    ABSTRACT The present study was carried out to assess the antitumor effect of venomous peptide from the cephalopod Octopus aegina on Ehrlich's ascites carcinoma (EAC). Male albino Swiss mice were used in the present study. Four groups of animals were treated with three doses of the sublethal dose of venom, 15, 75, and 150 mug/kg body weight (intraperitoneal injection), along with the standard drug 5-fluorouracil (20 mg/kg b.w.). After 10 days of treatment, six animals from each group were sacrificed for the biochemical analysis and the rest were left to calculate the mean survival time. In EAC-bearing mice, mean lifespan, tumor volume, hemoglobin, red blood cells, and lymphocytes were significantly decreased when compared to the normal animals. While body weight, neutrophils, and viable tumor cell count were increased in the EAC-bearing mice, these changes were brought back to near normal levels in different treatment groups. The macromolecule concentration of peritoneal cells, such as DNA, RNA, and protein, were altered in the EAC-bearing mice and observed to be near normal in the treatment groups. The caspase-3 activity was significantly increased in the peritoneal cells of the treatment groups when compared to the EAC-bearing mice. The role of apoptotic cascade in EAC cell death was confirmed by the DNA fragmentation on agarose gel. Apart from the antitumor effect, octopus venom reduced the tumor burden on the liver and altered the changes in the activities of alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP). Therefore, the venom from O. aegina has a potential antitumor effect on the EAC-bearing mice.

    Background Pulmonary arterial hypertension, also known as Ascites syndrome (AS), remains a clinically challenging disease with a large impact on both humans and broiler chickens. Pulmonary arterial remodeling presents a key step in the development of AS. The precise molecular mechanism of pulmonary artery remodeling regulating AS progression remains unclear. Methodology/Principal Findings We obtained pulmonary arteries from two positive AS and two normal broilers for RNA sequencing (RNA-seq) analysis and pathological observation. RNA-seq analysis revealed a total of 895 significantly differentially expressed genes (DEGs) with 437 up-regulated and 458 down-regulated genes, which were significantly enriched to 12 GO (Gene Ontology) terms and 4 KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways (Padj<0.05) regulating pulmonary artery remodeling and consequently occurrence of AS. These GO terms and pathways include ribosome, Jak-STAT and NOD-like receptor signaling pathways which regulate pulmonary artery remodeling through vascular smooth cell proliferation, inflammation and vascular smooth cell proliferation together. Some notable DEGs within these pathways included downregulation of genes like RPL 5, 7, 8, 9, 14; upregulation of genes such as IL-6, K60, STAT3, STAT5 Pim1 and SOCS3; IKKα, IkB, P38, five cytokines IL-6, IL8, IL-1β, IL-18, and MIP-1β. Six important regulators of pulmonary artery vascular remodeling and construction like CYP1B1, ALDH7A1, MYLK, CAMK4, BMP7 and INOS were upregulated in the pulmonary artery of AS broilers. The pathology results showed that the pulmonary artery had remodeled and become thicker in the disease group. Conclusions/Significance Our present data suggested some specific components of the complex molecular circuitry regulating pulmonary arterial remodeling underlying AS progression in broilers. We revealed some valuable candidate genes and pathways that involved in pulmonary artery remodeling further contributing to the AS

    Kabuki syndrome (MIM 147920) is a well-described, multiple congenital anomaly syndrome characterized by growth and developmental delay, cardiac, renal, and vertebral anomalies, as well as persistent fetal finger pads and distinct facial features. Facies are characterized by long palpebral fissures with eversion of lateral third of the lower eyelid, resembling the "Kabuki make-up" theatre genre after which the syndrome is named. Kabuki syndrome is estimated to affect 1/32,000 births, with 55-80% of patients showing nonsense or frameshift mutations in the KMT2D (MLL2) gene, which encodes a histone transferase located on chromosome 12q. Additionally, owing to the heterogeneous nature of Kabuki syndrome, a smaller number of diagnosed patients have been identified with mutations or deletions in KDM6A (a component of the same transcriptional complex as KMT2D) with no mutations in KMT2D, or as those diagnosed with Kabuki syndrome and without alterations in either KMT2D or KDM6A. Diagnosis of the syndrome in newborns and infants is difficult, as the facial features are not as evident as in toddler- or childhood. There are no known "tell-tale" signs of Kabuki syndrome prenatally, and there are no reports of common, specific findings in fetuses that might suggest the diagnosis. We present here two infants who presented with prenatal hydrops/ascites, who were subsequently diagnosed with Kabuki syndrome. Although relatively non-specific, we suggest that Kabuki syndrome be added to the list of genetic syndromes that are suspected in cases of prenatal hydrops, review the molecular etiology of Kabuki syndrome, and broaden the phenotype of this well-described disorder. © 2016 Wiley Periodicals, Inc.

    To best of our knowledge, this is the first reported case of pericardial and pleural effusions combined with ascites, precipitated with severe sunitinib-induced hypothyroidism. A 58-year-old man presented in our emergency department due to dyspnoea and dry cough. Sixteen months earlier, the patient underwent left nephrectomy due to metastatic renal cell adenocarcinoma (RCC), and therapy with sunitinib was initiated postoperatively. Thyroid function was not assessed during the therapy. On admission, all laboratory findings were within normal range. Computed tomography of the chest detected voluminous bilateral pleural effusions and mild pericardial effusion, and echocardiography revealed pericardial effusion. Thoracocentesis was carried out three times, and cytological examination showed no signs of malignant cells. After assessment of the thyroid function, neglected hypothyroidism was registered. Substitution therapy with levothyroxine was initiated, and thyroid function normalised 2 weeks later. Few days after the last thoracocentesis, his condition suddenly got worse. Thoracocentesis was repeated, and microbiological analysis of the exudate came positive for Klebsiella pneumoniae and Streptococcus pneumoniae. Despite the implemented therapeutic measures, his clinical condition progressively deteriorated. The patient died 27 days after the admission, hospital-acquired pneumonia was identified as the cause of death. Our case emphasises the necessity of careful monitoring and management of side-effects in patients who receive sunitinib. Hypothyroidism is a known cause of pleural, pericardial and abdominal effusions, as reported in several case reports. Timely initiation of substitution levothyroxine therapy can decrease unnecessary pauses in the therapy with sunitinib, as well as prevent development of severe symptoms.

    Forskolin increased intracellular cyclic AMP and augmented cyclic AMP formation by prostaglandin E1 (PGE1) in normal rat hepatocytes and ascites hepatoma AH66 cells. However, in AH66F cells which were derived from the AH66 cell line, the diterpene only slightly increased the cyclic AMP level, and dose-dependently inhibited the accumulation caused by PGE1. Forskolin dose-dependently activated adenylate cyclase in these membranes, and the magnitude of activation by forskolin was largest in the following order: hepatocytes, AH66 cells, and AH66F cells. This difference may be based on the number of forskolin-binding sites. The binding affinity of forskolin for each cell membrane was similar. The number and affinity of forskolin-binding sites in these cells were not influenced by 5'-guanylylimidodiphosphate [Gpp(NH)p]. In hepatocytes and AH66 cells, forskolin and other adenylate cyclase activators such as PGE1, GTP, Gpp(NH)p, F-, and Mn2+ synergistically increased the enzyme activity. In AH66F cells, the forskolin-stimulated activity was hardly influenced by the GTP analog, and forskolin diminished the activities induced by the GTP analog in a manner similar to that of diterpene alone. Forskolin (10 microM) also significantly inhibited the activities induced by PGE1, GTP, and F-. The effect of forskolin with Mn2+ was additive in AH66F cells. The data suggest that forskolin promotes the interaction between the stimulatory guanine nucleotide-binding protein and the catalytic unit in the membrane of normal hepatocytes and AH66 cells, but it interferes with the coupling in AH66F cells.

    Adenylate cyclase activation through adrenergic receptors in rat ascites hepatoma (AH) 130 cells in response to adrenergic drugs was studied, and receptor binding and displacement were compared with those of normal rat hepatocytes. Epinephrine (Epi) and norepinephrine (NE) activated AH130 adenylate cyclase about half as much as isoproterenol (IPN) but equaled IPN after treatment with the alpha-antagonist phentolamine or islet-activating protein (IAP). The three catecholamines in hepatocytes were similar regardless of phentolamine or IAP. These catecholamines activated adenylate cyclase in order of IPN greater than NE greater than Epi in AH130 cells but IPN greater than Epi greater than NE in hepatocytes. We then used the alpha 1-selective ligand [3H]prazosin, the alpha 2-selective ligand [3H]clonidine, and the beta-ligand [125I]iodocyanopindolol [( 125I]ICYP), and found that AH130 cells had few prazosin-binding sites, about eight times as many clonidine-binding sites with high affinity, and many more ICYP-binding sites than in hepatocytes. The dissociation constant (Ki) of the beta 1-selective drug metoprolol by Hofstee plots for AH130 cells was lower than that for hepatocytes. The inhibition of specific ICYP binding by the beta 2-selective agonist salbutamol for AH130 cells gave only one Ki value which was much higher than both high and low Ki values of the drug for hepatocytes. These findings indicate that the alpha- and beta-adrenergic receptors in hepatocytes are predominantly alpha 1-type and beta 2-type, but that those in AH130 cells are predominantly alpha 2-type and beta 1-type, and the low adrenergic response of AH130 cells is due to the dominant appearance of alpha 2-adrenergic receptors, linked with the inhibitory guanine-nucleotide binding regulatory protein, instead of alpha 1-adrenergic receptors, and beta 1-adrenergic receptors with low affinity for the hormone.

  6. Action of the antitumor and antispermatogenic agent lonidamine on electron transport in Ehrlich ascites tumor mitochondria.

    1983-10-01

    The effect of lonidamine, an antispermatogenic and antitumor drug, on the oxygen consumption, ATPase activity, and redox state of the electron carriers of Ehrlich ascites tumor mitochondria has been studied. Lonidamine inhibits ADP- and uncoupler-stimulated respiration on various NAD- and FAD-linked substrates, but does not affect state 4 respiration. Experiments to determine its site of action showed that lonidamine does not significantly inhibit electron flow through cytochrome oxidase. Electron flow through site 2, the ubiquinone-cytochrome b-cytochrome c1 complex, also was unaffected by lonidamine, which failed to inhibit the oxidation of duroquinol. Moreover, inhibition of electron flow through site 2 was also excluded because of the inability of the N,N,N',N'-tetramethyl-p-phenylenediamine bypass to relieve the lonidamine inhibition of the oxidation of pyruvate + malate. The F0F1ATPase activity and vectorial H+ ejection are also unaffected by lonidamine. The inhibition of succinate oxidation by lonidamine was found to take place at a point between succinate and iron-sulfur center S3. Spectroscopic experiments demonstrated that lonidamine inhibits the reduction of mitochondrial NAD+ by pyruvate + malate and other NAD-linked substrates in the transition from state 1 to state 4. However, lonidamine does not inhibit reduction of added NAD+ by submitochondrial vesicles or by soluble purified NAD-linked dehydrogenases. These observations, together with other evidence, suggest that electron transport in tumor mitochondria is inhibited by lonidamine at the dehydrogenase-coenzyme level, particularly when the electron carriers are in a relatively oxidized state and/or when the inner membrane-matrix compartment is in the condensed state. The action of lonidamine in several respects resembles the selective inhibition of electron transport in tumor cells produced by cytotoxic macrophages (D. L. Granger and A. L. Lehninger (1982) J. Cell Biol. 95, 527).

    The influence of boric acid, a boron carrier, on Ehrlich ascites carcinoma (EAC) cell-bearing mice was investigated in view of its importance in the boron neutron capture therapy and the influence of boron on proliferation and progression of cancer cells mediated by proteoglycans and collagen. The present study included the evaluation of boric acid for the effects on total count and viability of EAC cells in addition to their non-protein sulfhydryls (NP-SH) and malondialdehyde (MDA) contents as parameters for conjugative detoxication potency and possible oxidative damage. The EAC cell-bearing animals were also observed for the effect on survival, body weight changes, and histopathological evaluation of the tumors grown at the site of inoculation. The treatment with boric acid significantly increased the total number of peritoneal EAC cells and their viability. A significant increase in the body weight was observed that dose-dependently reached plateau levels by 20 days of treatment. Conversely, a reduction in the duration of survival of these animals was evident with the same protocol. Boric acid treatment resulted in a decrease in NP-SH contents with a concomitant increase in MDA levels in EAC cells as revealed by the results of the biochemical analysis. These data are supported by our results on histopathological investigations, which apparently showed fast growth, in addition to several mitotic figures and mixed inflammatory reaction, after treatment with boric acid. It seems likely that a particular combination of properties of boric acid, rather than a single characteristic alone, will provide useful information on the use of this boron carrier in neutron capture therapy.

    The continuing threat to biodiversity lends urgency to the need of identification of sustainable source of natural products. This is not so much trouble if there is a microbial source of the compound. Herein, violacein, a natural indolic pigment extracted from Chromobacterium violaceum, was evaluated for its antitumoral potential against the Ehrlich ascites tumor (EAT) in vivo and in vitro. Evaluation of violacein cytotoxicity using different endpoints indicated that EAT cells were twofold (IC(50)=5.0 microM) more sensitive to the compound than normal human peripheral blood lymphocytes. In vitro studies indicated that violacein cytotoxicity to EAT cells is mediated by a rapid (8-12h) production of reactive oxygen species (ROS) and a decrease in intracellular GSH levels, probably due to oxidative stress. Additionally, apoptosis was primarily induced, as demonstrated by an increase in Annexin-V positive cells, concurrently with increased levels of DNA fragmentation and increased caspase-2, caspase-9 and caspase-3 activities up to 4.5-, 6.0- and 5.5-fold, respectively, after 72 h of treatment. Moreover, doses of 0.1 and 1.0 microg kg(-1) violacein, administered intraperitoneally (i.p.) to EAT-bearing mice throughout the lifespan of the animals significantly inhibited tumor growth and increased survival of mice. In view of these results, a 35-day toxicity study was conducted in vivo. Complete hematology, biochemistry (ALT, AST and creatinine levels) and histopathological analysis of liver and kidney indicated that daily doses of violacein up to 1000 microg kg(-1) for 35 days are well tolerated and did not cause hematotoxicity nor renal or hepatotoxicity when administered i.p. to mice. Altogether, these results indicate that violacein causes oxidative stress and an imbalance in the antioxidant defense machinery of cells culminating in apoptotic cell death. Furthermore, this is the first report of its antitumor activity in vivo, which occurs in the absence of toxicity to

    Background: Cissampelos pareira (Menispermaceae) is used in folk Indian system of alternative medicine, for its analgesic, antipyretic, diuretic, antilithic, and emmenagogue properties. Objective: To evaluate Cissampelos pareira (C. pareira) for in vitro cytotoxicity and in vivo antitumor activity against Dalton's Lymphoma Ascites (DLA) cells in Swiss mice. Materials and Methods: Cissampelos pareira was successively extracted using different solvents. In vitro cytotoxicity was assessed by the MTT assay. An in vivo study was carried out in methanol extract. Twenty-four hours after intraperitoneal inoculation of the DLA cells in mice, the methanol extract of C. pariera (MECP) was administered at 200 and 400 mg/kg body weight for 14 consecutive days. On day 14, six mice were sacrificed and the rest were kept alive for assessment of increase in life-span. The antitumor effect was assessed by evaluating the packed cell volume, viable tumor cell count, increase in body weight, and increase in life-span. The hematological and serum biochemical parameters and anti-oxidant properties were assessed by estimating the superoxide dismutase (SOD), catalase (CAT), and lipid peroxidation. Results: Methanol Extract of Cissampelos pariera (MECP) showed a potent cytotoxic activity, with an IC50 value of 95.5 μg/ml and a significant (P < 0.001) decrease in packed cell volume, viable cell count, and an increased lifespan (54 and 72%). The hematological and serum biochemical profiles were restored to normal levels in MECP-treated mice. The MECP-treated group significantly (P < 0.001) decreased SOD, lipid peroxidation, and CAT to normal. Conclusion: This study demonstrated that C. pariera exhibited significant in vitro and in vivo anti-tumor activities and that it was reasonably imputable to its increasing endogenous mechanism of antioxidant property.

    Previously, we demonstrated that caffeine, a natural alkaloid, stimulates increased incidences of pulmonary hypertension syndrome (ascites) in broilers. The present study was designed to evaluate the ergogenic effects of caffeine on broiler performance and blood parameters. One-hundred-and-ninety-two Ross 308 male broiler chicks were randomly assigned at one d of age to 16 pens with 4 treatment groups. On d 3, the drinking water was supplemented with caffeine at levels of zero, 12.5, 25, and 50 mg/kg BW/day. Caffeine supplementation linearly improved (P < 0.01) body weight gain (BWG) and the feed conversion ratio (FCR); however, feed intake was not affected by caffeine (P > 0.05). On d 28, increasing caffeine supplementation caused linear reductions in plasma albumin, total protein, globulin, and triglyceride concentrations, and caffeine supplementation increased plasma uric acid concentrations (P < 0.05). On d 42, caffeine did not consistently affect plasma albumin, globulin, triglyceride, total protein, uric acid, or urea concentrations (P > 0.05), whereas plasma glucose concentrations increased linearly with increasing caffeine levels (P < 0.05). Plasma T4 concentrations were not affected by caffeine (P > 0.05), but plasma T3 concentrations were reduced by caffeine supplementation on d 28 and 42 (P < 0.05). The T3:T4 ratios also were reduced by caffeine supplementation on d 42. Skin temperature was not influenced by caffeine supplementation (P > 0.05). There was a negative correlation between thyroid hormone concentrations and BW on d 42 (P < 0.05). It can be concluded that caffeine supplementation at the levels of 12.5 to 25 mg/kg BW/day increased BWG, decreased FCR and T3, and significantly altered blood biochemistry parameters.

  11. Ca2+ transport by mitochondria from L1210 mouse ascites tumor cells.

    Mitochondria isolated from the ascites form of L1210 mouse leukemia cells readily accumulate Ca(2+) from the suspending medium and eject H(+) during oxidation of succinate in the presence of phosphate and Mg(2+), with normal stoichiometry between Ca(2+) uptake and electron transport. Ca(2+) loads up to 1600 ng-atoms per mg of protein are attained. As is the case in mitochondria from normal tissues, Ca(2+) uptake takes precedence over oxidative phosphorylation. However, Ca(2+) transport by the L-1210 mitochondria is unusual in other respects, which may possibly have general significance in tumor cells. The apparent affinity of the L1210 mitochondria for Ca(2+) in stimulation of oxygen uptake is about 3-fold greater than in normal liver mitochondria; moreover, the maximal rate of Ca(2+) transport is also considerably higher. Furthermore, when Ca(2+) pulses are added to L1210 mitochondria in the absence of phosphate or other permeant anions, much larger amounts of Ca(2+) are bound and H(+) ejected per atom of oxygen consumed than in the presence of phosphate; up to 7 Ca(2+) ions are bound per pair of electrons passing each energy-conserving site of the electron-transport chain. Such "superstoichiometry" of Ca(2+) uptake can be accounted for by two distinct types of respiration-dependent interaction of Ca(2+) with the L1210 mitochondria. One is the stimulation of oxygen consumption, which is achieved by relatively low concentrations of Ca(2+) (K(m) congruent with 8 muM) and is accompanied by binding of Ca(2+) up to 40 ng-atoms per mg of protein. The second process, also dependent on electron transport, is the binding of further Ca(2+) from the medium in exchange with previously stored membrane-bound protons, in which the affinity for Ca(2+) is much lower (K(m) congruent with 120 muM).

    Introduction C-Reactive Protein (CRP) is an acute phase reactant. Its level increases in the presence of acute or chronic inflammation and infections. High sensitive CRP (hs-CRP) is more sensitive than CRP as an inflammatory marker. High sensitive CRP has been known to be elevated in chronic liver diseases and Spontaneous Bacterial Peritonitis (SBP). Aim The aim of the study was to establish the role of ascitic fluid high sensitive C-reactive protein (hs –CRP) as a prognostic indicator in patients with SBP. Materials and Methods A total of 100 patients with decompensated cirrhosis admitted in medicine ward and ICU were included, of which 50 patients of acute bacterial peritonitis were used as study group and 50 patients of sterile ascites were used as control group. Hs-CRP level of cases and controls were estimated. SBP cases were treated with its standard recommended antibiotic therapy and hs-CRP level was again estimated after 5 days of antibiotic therapy or at the time of discharge. Results The mean level of hs-CRP before antibiotic therapy of the patients with SBP was significantly higher than that of the patients without spontaneous bacterial peritonitis (t98=17.72; p=0.0001). The mean level of hs-CRP at 5th day or discharge after initiation of antibiotic therapy was significantly lower than that of level of hs-CRP before initiation of antibiotic therapy (p<0.05). The mean hs-CRP of the cases with poor outcome (death and prolonged hospital stay) was significantly higher than others. Conclusion Ascitic fluid hs-CRP level can be considered as a surrogate prognostic marker in cases of Cirrhosis with SBP. PMID:27190862

  13. Proteomic identification of fucosylated haptoglobin alpha isoforms in ascitic fluids and its localization in ovarian carcinoma tissues from Mexican patients

    2014-01-01

    Background Ovarian cancer is the most lethal gynecologic disease due to delayed diagnosis, and ascites production is a characteristic of patients in advanced stages. The aim of this study was to perform the proteomic analysis of ascitic fluids of Mexican patients with ovarian carcinoma, in order to detect proteins with a differential expression pattern in the continuing search to identify biomarkers for this disease. Methods Samples were collected from 50 patients from the Instituto Nacional de Cancerología of México under informed consent and with approval of the bioethics and scientific committees. After elimination of abundant proteins (Albumin/IgGs) samples were processed for 2D electrophoresis and further protein identification by Mass Spectrometry (MALDI-TOF). Molecules of interest were followed by western blot and lectin binding assays, and their tissue location by histo-immunofluorescence and confocal analysis. Results and discussion An area with a differential expression pattern among samples was located in the 2D gels. Identified proteins were 6 alpha 1 isoforms and 1 alpha 2 isoform of Haptoglobin, and 2 isoforms of Transthyretin. While Transthyretin isoforms were constitutively expressed in all samples, clear differences in the expression pattern of Haptoglobin alpha isoforms were found. Moreover, increased levels of fucosylation of Haptoglobin alpha isoforms analyzed in 40 samples by Aleuria aurantia lectin binding by 1D overlay assay showed a positive correlation with advanced stages of the disease. Tissue detection of Haptoglobin and its fucosylated form, by histo-immunofluorescence in biopsies of ovarian cancer, also showed a correlation with ovarian cancer progression. Moreover, results show that fucosylated Haptoglobin is produced by tumor cells. Conclusions Increased numbers of highly fucosylated Haptoglobin alpha isoforms in ascitic fluids and the presence of fucosylated Haptoglobin in tumor tissues of ovarian cancer Mexican patients

    Background Overexpression of inducible nitric oxide synthase (iNOS) and increased nitric oxide generation may be associated with the hyperdynamic circulation of patients with cirrhosis. We have, for the first time, used the highly selective iNOS inhibitor, 1400W, to determine whether iNOS activity contributes to the regulation of vascular tone in patients with cirrhosis and ascites. Methods Bilateral forearm blood flow was measured using strain gauge plethysmography in eight patients with cirrhosis and ascites, and eight matched healthy volunteers during intrabrachial infusion of 1400W (0.1–1 μmol/min), NG‐monomethyl‐L‐arginine (L‐NMMA, a non‐selective NOS inhibitor; 2–8 μmol), and norepinephrine (a control vasoconstrictor; 60–480 pmol/min). Results In patients with cirrhosis, 1400W, L‐NMMA, and norepinephrine caused dose dependent reductions in forearm blood flow: peak reductions of 11 (5)%, 37 (4)%, and 48 (5)%, respectively (p<0.05 for all). In contrast, 1400W had no effect on blood flow (+4 (8)%; NS) in healthy controls despite similar reductions in blood flow with L‐NMMA and norepinephrine (39 (5)% and 49 (5)%, respectively; p<0.05 for both). Conclusions We have, for the first time, demonstrated that 1400W causes peripheral vasoconstriction in patients with cirrhosis but not healthy matched controls. This suggests that iNOS contributes to the regulation of peripheral vascular tone in patients with cirrhosis and ascites, and may contribute towards the hyperdynamic circulation associated with this condition.

    A 56-year-old man was diagnosed with aplastic anemia and paroxysmal nocturnal hemoglobinuria at 43 years of age and treatment with cyclosporin A was started. Liver cirrhosis, ascites, and thrombus in the hepatic veins were found at 56 years of age and Budd-Chiari syndrome (BCS) was diagnosed according to angiography findings. He was treated with diuretics and paracentesis was performed several times, but with limited efficacy. A DenverⓇ peritoneovenous shunt (PVS) was inserted into the right jugular vein; his ascites and renal function improved immediately and his general condition has remained good for 12 months since starting the above treatment regimen. A PVS is a treatment option for ascites due to BCS. PMID:27746432

    Ascites is a major complication of liver cirrhosis which carries a poor prognosis. Diuretics are used in treatment of ascites in addition to salt restriction. Monitoring of diuretic response can be achieved by measurement of 24 hours urinary sodium. This study evaluated the accuracy of using spot urinary sodium/potassium ratio as a reliable alternative to 24 hours urinary sodium in assessment of dietary sodium compliance in patients with liver cirrhosis receiving diuretics. Fifty patients presented with liver cirrhosis and ascites were divided into 2 groups: GI 14 (28%) patients diuretic resistant with 24 hours urinary sodium < 78 mEq) and GII 36 (72%) patients diuretic sensitive with 24 hours urinary sodium > 78 mEq. The results showed highly significant correlation between 24 hours urinary sodium and spot urine sodium/potassium ratio with sensitivity 87.5% specificity 56% and accuracy 70% at cutoff point of 1.8.

    To clarify unknown rationalities of herbaceous compatibility of Euphorbia Pekinensis (DJ) and Glycyrrhiza glabra (GC) acting on hepatocellular carcinoma (HCC) ascites, peritoneum transcriptomics profiling of 15 subjects, including normal control (Con), HCC ascites mouse model (Mod), DJ-alone, DJ/GC-synergy and DJ/GC-antagonism treatment groups were performed on OneArray platform, followed by differentially expressed genes (DEGs) screening. DEGs between Mod and Con groups were considered as HCC ascites-related genes, and those among different drug treatment and Mod groups were identified as DJ/GC-combination-related genes. Then, an interaction network of HCC ascites-related gene-DJ/GC combination-related gene-known therapeutic target gene for ascites was constructed. Based on nodes’ degree, closeness, betweenness and k-coreness, the Frk-Arhgdib-Inpp5d-Avpr2-Aqp4 axis with highly network topological importance was demonstrated to be a candidate target of DJ/GC combination acting on HCC ascites. Importantly, both qPCR and western blot analyses verified this regulatory effects based on HCC ascites mice in vivo and M-1 collecting duct cells in vitro. Collectively, different combination designs of DJ and GC may lead to synergistic or antagonistic effects on HCC ascites partially via regulating the Frk-Arhgdib-Inpp5d-Avpr2-Aqp4 axis, implying that global gene expression profiling combined with network analysis can offer an effective way to understand pharmacological mechanisms of traditional Chinese medicine prescriptions.

    Liver cirrhosis is frequently accompanied by malnutrition and hypoalbuminemia, which in turn commonly induces ascites in patients with liver cirrhosis. Ascites leads to abdominal distention and appetite loss, resulting in a deteriorated quality of life (QOL). Administration of branched-chain amino acid (BCAA)-rich supplements reduces hepatic encephalopathy and malnutrition. In addition, BCAAs by themselves up-regulate albumin synthesis through an increase in Fisher's ratio. Thus, in patients with liver cirrhosis, BCAA-rich supplements seem to be effective at reducing ascites and improving the QOL. Here, we report the case of a 58-year-old Japanese man with liver cirrhosis with severe ascites and peripheral edema. The hepatic function of the patient was classified as Child-Pugh grade C. To reduce protein-energy malnutrition, BCAA-rich supplements were administered as a late evening snack as part of a regimen including 2000 kcal/day (32.5 kcal/kg/day) of total energy and 83.5 g/day (1.3 g/kg/day) of total protein intake. Eight weeks after admission, ascites and edema had decreased. Nutritional status also improved from the time of admission to discharge; the serum BCAA level increased from 365.4 to 450.2 µmol/l. Furthermore, the ratio of BCAAs to tyrosine (BTR) increased from 1.70 to 3.65. We also evaluated the effects of nutritional therapy on the patient's QOL using the Medical Outcomes Study 36-Item Short-Form Health Survey upon admission and at discharge. All subscores showed marked improvement and reached a level greater than the Japanese norm with nutritional treatment. In conclusion, BCAA supplementation not only reduced ascites, but also improved the QOL in a patient with liver cirrhosis.

    Pulmonary vascular remodelling, mainly characterized by arterial medial thickening, is an important pathological feature of broiler ascites syndrome (AS). Since vascular smooth muscle cells (VSMC) form the major cellular component of arterial medial layer, we speculate that VSMC proliferation is one of the causes of pulmonary arterial medial thickening in ascitic broilers. Hence, the present study was designed to investigate the role of VSMC proliferation in pulmonary vascular remodelling in development of AS induced by low ambient temperature. Broilers in control group (22 +/- 1.5 degrees C) and low temperature group (11 +/- 2 degrees C) were sampled every week at 15-50 days of age. Proliferative indexes of VSMC in pulmonary arteries were assessed with proliferating cell nuclear antigen, and the relative medial thickness (RMT) and relative wall area (RWA), as indexes of pulmonary vascular remodelling, were examined by computer-image analysing system. The results showed that the high incidence (18.75%) of AS was induced by low temperature, and a significantly increased VSMC proliferation was observed in pulmonary arteries in the low temperature group at 22-50 days of age (P < 0.05). In addition, RMT and RWA in pulmonary arteries were significantly elevated in the low temperature group from 36 days of age (P < 0.05), indicating that pulmonary vascular remodelling occurred following VSMC proliferation in AS. Our data suggest that proliferation of VSMC may facilitate pulmonary vascular remodelling and have a pivotal role in AS induced by low ambient temperature.

    The inhibitory effect of phenothiazines in tumor growth and cancer cell proliferation in vitro and in vivo has been established. These reports motivated us to investigate the genotoxic, cytotoxic, and cytostatic potential of chlorpromazine, alone or in combination with mitomycin C, in vitro and in vivo. Sister chromatid exchange levels were assessed providing a quantitative index of genotoxicity. In-vitro studies were performed on human lymphocyte cultures and in-vivo studies involved Ehrilch ascites tumor (EAT) cells. An antitumour study was also conducted on the survival time and the ascitic volume in EAT-bearing Balb/C mice. The combination of chlorpromazine plus caffeine and mitomycin C exerted cytostatic and cytotoxic actions in human lymphocytes. The combination of chlorpromazine plus mitomycin C exerted cytostatic and cytotoxic actions in EAT cells, significantly increased the survival span of the mice inoculated with EAT cells, and suppressed the expected tumor growth increase. The findings of this basic study illustrate that high chlorpromazine concentrations increase chemotherapeutic effectiveness of mitomycin C. Chlorpromazine concentrations within the observed human plasma concentration range need to be tested along with antineoplastic agents in vitro for its synergistic action so as to evaluate a potential clinical application. Further investigation including other phenothiazines, biological systems, and cancer models is required.

    Distinguishing reactive changes from neoplastic processes during lymphoid tissue evaluation is oftentimes difficult. Ancillary studies, such as flow cytometry, may aid the diagnosis by demonstrating monotypic or polytypic light chain expression on the B cells. The detection of immunoglobulin light chain restricted B cell population is considered a surrogate marker of clonality, which can be confirmed by molecular assays. In general, the presence of a monotypic B cell population in the ascitic fluid is considered lymphomatous involvement rather than a reactive condition. We describe a young, previously healthy male patient who developed ascites with a lambda light chain restricted B cell population. Further investigation revealed florid follicular hyperplasia, histologically mimicking diffuse large B cell lymphoma, in the terminal ileum. Follicular hyperplasia in the gastrointestinal tract with lambda light chain restricted B cells has been recently described in the pediatric population. Importantly, our case demonstrates that such entity can occur in older age groups. This recognition could prevent misdiagnosis and unnecessary treatment in similar cases.

    Background: North East India is a rich source of medicinal plants and a number of plant extracts are used by tribal peoples living in this area for various disorders. L.aspera is such a plant, traditionally used as an antitumor agent. Aim: In the present study, aerial parts of L.aspera were investigated for antitumor activity in Dalton's lymphoma (DAL) bearing mice. The ability of plant extract in free radical scavenging, neoangiogenesis inhibition and macrophage stimulation were also checked. Materials and Methods: Based on the preliminary in vitro cytotoxicity studies ethyl acetate fraction of L.aspera (EALA) was selected for the detailed study. DAL ascites tumor model was performed to check the antitumor activity of EALA (200 and 400mg/kg of body weight). Hematological and histopathological parameters were estimated. Antioxidant levels, neoangiogenesis and peritoneal macrophage count were also determined. Results: In vitro MTT and Trypan blue assay results showed the cytotoxic effect of EALA in DAL cells lines. EALA treatment resulted in significant decrease in ascites tumor volume and viable cell count. Hematological and liver antioxidant parameters were normalised by EALA treatment. It was also found that EALA treatment inhibits neovascularisation and produce macrophage stimulation in treated mice. Conclusion: The results showed that EALA is a promising anticancer agent and its activity is comparable to the standard drug 5-Flouro uracil (5-FU). PMID:24914276

    Usnic acid (UA) can be found in certain lichen species. Growing evidence suggests that UA possesses antitumoral, antioxidative and anti-inflammatory activities. Bleomycin (BLM) is widely used in the treatment of malignant ascites, however, it unexpectedly causes pulmonary fibrosis (PF). Researches show that excessive inflammatory response and oxidative stress in lung tissue is conspicuous causes of BLM-induced PF. Here we investigated mechanism underlying the effect-enhancing and toxicity-reducing activity of UA on H22-bearing mice treated with BLM. UA combined with BLM was significantly more effective than BLM alone in inhibiting the tumor growth, arresting the cell cycle at G0/G1 phase, and promoting the cleaved caspase-3 and cleaved caspase-8 activities to induce cancer cellular apoptosis. The mechanism may be associated with the transcriptional regulation of p53/p21/Cyclin pathway. Furthermore, UA effectively moderated the histopathological changes, reduced the content of MDA, HYP, TNF-α, IL-1β, IL-6 and TGF-β1, and increased the level of SOD when combined with BLM in lung tissues of H22-bearing mice, which was believed to be related to the inhibition on the protein level of p-Smad2/3 and enhancement of Smad7 expression. These findings suggested that UA might be a potential effect-enhancing and toxicity-reducing candidate for BLM in the treatment of malignant ascites.

    This cross sectional study was carried out in the department of gastroenterology, BIRDEM, Dhaka from January 2010 to May 2011 to determine the role of ascitic fluid ADA and serum CA-125 in the diagnosis of clinically suspected tubercular peritonitis. Total 30 patients (age 39.69 ± 21.26, 18M/12F) with clinical suspicion of tuberculosis peritonitis were included in this study after analyzing selection criteria. Laparoscopic peritoneal biopsy with 'histopathological diagnosis' was considered gold standard against which accuracics of two biomarkers (ADA & CA-125) were compared. Cut off value of ADA and CA-125 are 24 u/l, 35 U/ml respectively. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ADA as a diagnostic modality in tuberculos peritonitis were 87.5%, 83.33%, 95.45%, 62.5% and 86.67% respectively where as CA-125 was found to have 83.33% sensitivity, 50% specificity, 86.9% positive predictive value, 42.85% negative predictive value and 76.6% accuracy. Both biomarkers are simple, non-invasive, rapid and relatively cheap diagnostic test where as laparoscopy is an invasive procedure, costly & requires trained staff and not without risk and also not feasible in all the centre in our country. So ascitic fluid ADA and serum CA-125 are important diagnostic test for peritoneal tuberculosis.

    Introduction Ovarian cancer ascitic fluid, which contains malignant cells, is usually present in women with an advanced stage disease. There are currently no effective therapies for the treatment of ovarian cancer ascitic fluid. We developed a new therapeutic strategy to target expression of the diphtheria toxin fragment A gene in ovarian tumor cells under the control of H19 regulatory sequences. Case presentation A 64-year-old Caucasian woman was diagnosed with a stage IIIc epithelial ovarian cancer. She suffered from progressive disease, accumulation of malignant ascites that needed to be drained weekly, abdominal pain, vomiting, anorexia and severe weakness. Infusion of the diphtheria toxin A chain-H19 plasmid into the peritoneum of our patient resulted in complete resolution of the ascites with minimum adverse events. Conclusion On the basis of this preliminary experience, we are currently conducting an extensive Phase I study on a larger number of patients in order to assess the safety and preliminary efficacy of this novel patient-oriented treatment approach.

    Two experiments were conducted to evaluate the effects of early feed restriction on lipid peroxidation, pulmonary vascular remodelling and ascites incidence in broilers under normal and low ambient temperature. In experiment 1, the restricted birds were fed 8h per day either from 7 to 14 d or from 7 to 21 d, while the controlled birds were fed ad libitum. In experiment 2, the restricted birds were fed 80 or 60% of the previous 24-h feed consumption of full-fed controls for 7 d from 7 to 14 d. On d 14, half of the birds in each treatment both in experiment 1 and experiment 2 were exposed to low ambient temperature to induce ascites. Body weight and feed conversion ratio were measured weekly. The incidences of ascites and other disease were recorded to determine ascites morbidity and total mortality. Blood samples were taken on d 14, 21, 28, 35 and 42 to measure the plasma malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). On d 42, samples were taken to determine the right/total ventricular weight ratio (RV/TV), vessel wall area/vessel total area ratio (WA/TA) and mean media thickness in pulmonary arterioles (mMTPA). Low-temperature treatment increased plasma MDA concentration. When broilers were exposed to a cool environment for 3 weeks, plasma SOD and GSH-Px activity were decreased compared with normal-temperature chicks. RV/TV, WA/TA and mMTPA on d 42 were increased in birds exposed to cold, consistent with the increased pulmonary hypertension and ascites morbidity. Early feed restriction markedly decreased plasma MDA concentration. The plasma SOD and GSH-Px activity of feed-restricted birds were markedly higher than those fed ad libitum on d 35 and d 42. All early feed restriction treatments reduced ascites morbidity and total mortality. On d 42, the RV/TV, WA/TA and mMTPA of feed-restricted broilers were lower than that of the ad libitum-fed broilers. The results suggested that early feed restriction alleviated the lipid

    The effects of dietary garlic bulb were studied separately on hematological parameters, ascites incidence, and growth performance of an ascites susceptible broiler hybrid under both standard temperature conditions ( STC: ) and cold temperature conditions ( CTC: ). A total of 336 one-day-old male broiler chickens were allocated to 4 experimental groups with 4 replicates of 21 birds each under STC. In addition, the same grouping with another 336 birds was used for CTC. Under CTC, the birds were exposed to cold temperatures for induction of ascites. Experimental groups were defined by the inclusion of 0 (control), 5, 10 or 15 g/kg garlic bulbs in the diets under both STC and CTC. Growth performance, systolic blood pressure (as a measure of systemic arterial blood pressure), physiological and biochemical parameters, as well as ascites indices (right ventricle [ RV: ], total ventricle [ TV: ] weights, and RV/TV: ) were evaluated. Systolic blood pressure was determined using an indirect method with a sphygmomanometer, a pediatric cuff, and a Doppler device. The final body weight decreased quadratically (P = 0.003), with increasing garlic bulb levels in the diets under STC. The feed conversion ratio showed no significant differences among all groups under both STC and CTC. No significant differences were observed in total mortality and ascites-related mortality in all groups under STC, although total mortality (L: P = 0.01; Q: P = 0.001) and ascites-related mortality (L: P = 0.007; Q: P = 0.001) were significantly different among the diets under CTC. Under STC, the systolic blood pressure, packed cell volume, hemoglobin, RV, TV, and RV/TV did not vary significantly among the diets. However, red blood cell count and erythrocyte osmotic fragility decreased linearly (P < 0.005) with increasing garlic bulb levels in the diets under STC. Under CTC, the systolic blood pressure, packed cell volume, red blood cell count, and erythrocyte osmotic fragility decreased

    AIM: To observe the regulatory effect of Chinese herbal medicine on peritoneal lymphatic stomata and its significance in treating ascites in liver fibrosis model mice. METHODS: Two Chinese herbal composite prescriptions were used separately to treat the carbon tetrachloride-induced mouse model of liver fibrosis. The histo-pathologic changes of the liver sections (HE and VG stainings) were observed. The peritoneal lymphatic stomata was detected by scanning electron microscopy and computer image processing. The changes of urinary volume and sodium ion concentration were measured. RESULTS: In the model group, lots of fibrous tissue formed in liver and extended into the hepatic lobules to separate them incompletely. In the treated and prevention groups, the histo-pathologic changes of liver was rather milder, only showed much less fibrous tissue proliferation in the hepatic lobules. The peritoneal lymphatic stomata enlarged with increased density in the experimental groups (diameter: PA, 3.07 ± 0.69 µm; PB, 2.82 ± 0.37 µm; TA, 3.25 ± 0.82 µm and TB, 2.82 ± 0.56 µm; density: PA, 7.11 ± 1.90 stomata·1000 µm-2; PB, 8.76 ± 1.45 stomata·1000 µm-1; TA, 6.55 ± 1.44 stomata·1000 µm-2 and TB, 8.76 ± 1.79 stomata·1000 µm-2), as compared with the model group (diameter: 2.00 ± 0.52 µm; density: 4.45 ± 1.05 stomata·1000 µm-2). After treatment, the urinary volume and sodium ion excretion increased in the experimental groups (PA, 231.28 ± 41.09 mmol·L-1; PB, 171.69 ± 27.48 mmol·L-1 and TA, 231.44 ± 34.12 mmol·L-1), which were significantly different with those in the model group (129.33 ± 36.75 mmol·L-1). CONCLUSION: Chinese herbal medicine has marked effects in alleviating liver fibrosis, regulating peritoneal lymphatic stomata, improving the drainage of ascites from peritoneal cavity and causing increase of urinary volume and sodium ion excretion to reduce the water and sodium retention, and thus have favorable therapeutic effect in treating ascites

    Normalization of the increased vascular nitric oxide (NO) generation with low doses of NG-nitro-L-arginine methyl ester (L-NAME) corrects the hemodynamic abnormalities of cirrhotic rats with ascites. We have undertaken this study to investigate the effect of the normalization of vascular NO production, as estimated by aortic cyclic guanosine monophosphate (cGMP) concentration and endothelial nitric oxide synthase (eNOS) protein expression in the aorta and mesenteric artery, on sodium and water excretion. Rats with carbon tetrachloride-induced cirrhosis and ascites were investigated using balance studies. The cirrhotic rats were separated into two groups, one receiving 0.5 mg/kg per day of L-NAME (CIR-NAME) during 7 d, whereas the other group (CIR) was administrated the same volume of vehicle. Two other groups of rats were used as controls, one group treated with L-NAME and another group receiving the same volume of vehicle. Sodium and water excretion was measured on days 0 and 7. On day 8, blood samples were collected for electrolyte and hormone measurements, and aorta and mesenteric arteries were harvested for cGMP determination and nitric oxide synthase (NOS) immunoblotting. Aortic cGMP and eNOS protein expression in the aorta and mesenteric artery were increased in CIR as compared with CIR-NAME. Both cirrhotic groups had a similar decrease in sodium excretion on day 0 (0.7 versus 0.6 mmol per day, NS) and a positive sodium balance (+0.9 versus +1.2 mmol per day, NS). On day 7, CIR-NAME rats had an increase in sodium excretion as compared with the CIR rats (sodium excretion: 2.4 versus 0.7 mmol per day, P < 0.001) and a negative sodium balance (-0.5 versus +0.8 mmol per day, P < 0.001). The excretion of a water load was also increased after L-NAME administration (from 28+/-5% to 65+/-7, P < 0.05). Plasma renin activity, aldosterone and arginine vasopressin were also significantly decreased in the CIR-NAME, as compared with the CIR rats. The results thus indicate

    The present study examines ultrastructural and molecular changes in ventricular myocardium associated with ascites cases in fast-growing broilers raised at low altitude. Extensive ultrastructural lesions were seen in the left and right ventricular myocardium of broilers with fulminant heart failure and ascites. Significant changes included lesions in the myofibril contractile apparatus, altered mitochondria, marked reduction in the myofibril component, and changes in the extracellular matrix (ECM) architecture. No lesions were observed in hearts of slow growing broilers, but mild to moderate changes (predominantly in the left ventriculum) were apparent in the hearts from some clinically normal, fast-growing broilers. SDS-PAGE profiles of washed myofibrils showed several distinctly different bands in preparations from left ventricular myocardium of ascitic birds. Western blot analysis of these samples revealed several fragments of myosin heavy chain, M-protein, and titin. Based on gelatinolytic activity, matrix metalloproteinases (MMP) in the cytosolic fraction of ventricular myocardium homogenates were identified as MMP-2. The relative activity of this enzyme appears to be considerably higher in preparations from broilers, particularly in the preparations from the left ventriculum of fast-growing broilers, in comparison to leghorns or slow growing broilers. The nature and distribution of the changes in the heart indicate that chronic cardiomyopathic process in the left ventricular myocardium occurs during the development of ascites. It is postulated that progressive deterioration of the left heart pump function caused by initial lesions in the left ventricular myocardium is a significant factor in the development of pulmonary hypertension and the pathogenesis of ascites in broilers raised at low altitude.

    Ascites is a major cause of mortality and morbidity in modern broiler production. Reduction of early growth, followed by compensatory gain, seems a practical and viable method to minimize losses caused by ascites. An experiment was conducted to determine if early feed restriction can reduce the incidence of ascites in broilers exposed to cool temperatures. Ross 308 cockerels (N=180) were assigned to 5 diet treatments and 2 temperature regimes, with 3 replicate pens of 6 birds per treatment and temperature. A standard grower diet was diluted by adding rice hulls at 0, 15, 30, 45, and 60% by weight from 7 to 14 d of age. On d 21 through 42, the temperature was maintained at 20 to 25°C (thermoneutral), or at 11 to 15°C (cool). Broilers exposed to cool temperatures developed higher right ventricle (RV) to total ventricle (TV) and RV to BW ratios, increased plasma triiodothyronine (T3) and thyroxine (T4) concentrations, and elevated blood values for hemoglobin concentration, mean cell volume, and hematocrit (P<0.05) but did not develop clinical ascites. Diluting the feed with rice hulls from d 7 to 14 resulted in proportional reductions in BW by d 14 (P<0.001) that tended to persist through d 28 (P=0.005), after which compensatory growth eliminated all differences in BW between diet treatment groups by d 35 (P=0.099) and d 42 (P>0.1). Exposure to cool temperatures increased key indices of ascites susceptibility, and these preascitic changes were partially prevented by diluting the feed to reduce growth performance.

Here, we modeled the effects of GS/GC combination with a target interaction network and clarified the associations between the network topologies involving the drug targets and the drug combination effects. Moreover, the "edge-betweenness" values, which is defined as the frequency with which edges are placed on the shortest paths between all pairs of modules in network, were calculated, and the ADRB1-PIK3CG interaction exhibited the greatest edge-betweenness value, suggesting its crucial role in connecting the other edges in the network. Because ADRB1 and PIK3CG were putative targets of GS and GC, respectively, and both had functional interactions with AVPR2 approved as known therapeutic target for ascites, we proposed that the ADRB1-PIK3CG-AVPR2 signal axis might be involved in the effects of the GS-GC combination on ascites. This proposal was further experimentally validated in a H22 hepatocellular carcinoma (HCC) ascites model. Collectively, this systems-level investigation integrated drug target prediction and network analysis to reveal the combination principles of the herbal pair of GS and GC. Experimental validation in an in vivo system provided convincing evidence that different combination designs of GS and GC might result in synergistic or antagonistic effects on HCC ascites that might be partially related to their regulation of the ADRB1-PIK3CG-AVPR2 signal axis.

    ATP depletion in EL-4 ascites tumour cells rapidly induced the changes in cell morphology (blebbing), cytoskeletal protein assembly and finally resulted in cell death. After 1 hr of incubation with 2 microM rotenone (inhibitor of respiration) in glucose-free medium, when ATP level was 4% of the initial level, there were increases in triton-insoluble actin and vinculin levels (2.5-fold and 2.8-fold, respectively) and 44% of cells showed blebs; such treatment damaged cells irreversibly. Ca2+ removal did not diminish the effect of ATP depletion on cytoskeleton, blebbing and cell death, although the elevation of free intracellular Ca2+ in rotenone-treated cells was prevented. The role of ATP in maintaining cytoskeleton and cell shape is discussed.

    The pharmacological specificity of adrenergic receptors in the plasma membrane of rat ascites hepatoma AH130 cells was compared with that in normal rat hepatocytes. The number of [125I]iodocyanopindolol-binding sites was much greater in AH130 cells than in the hepatocytes. We characterized the alpha-adrenergic receptor subtypes using the alpha 1-selective ligand [3H]prazosin and the alpha 2-selective ligand [3H]clonidine. AH130 cells had fewer prazosin-binding sites than the hepatocytes and about 8 times as many clonidine-binding sites of high affinity. The results showed that the adrenergic receptors in AH130 cells have pharmacological properties that are very different from those of the receptors in normal rat hepatocytes.

    The budding of a tumor-adapted strain of influenza A0 virus at the surface of Ehrlich ascites tumor cells was studied by electron microscopy. Thin sections of budding sites showed the formation of a fuzzy coat on the outside of the cell membrane and simultaneously the apposition of a dark layer on the inner side. The continuity of cellular and viral membrane seemed to be preserved up to the point where the virion remained attached by only a thin stalk. Freeze-etching of virus budding sites yielded pictures in which a clear differentiation between the viral membrane and the host cell membrane was visible. The breaks across the fuzzy coat revealed striations corresponding to the “spikes” seen in negative contrast, whereas tangentially broken virus particles were best interpreted by assuming that splitting occurred midway between the two outer layers of the envelope.

    Abstract Background: Plasmacytoid urothelial carcinoma (PUC) is a distinct variant of urinary bladder cancer, with a high propensity for invasion and poor prognosis. These tumors occur most commonly in male patients with the age of reported cases ranging from 46 to 87 years. Case report: We present a case of a 74-year-old male patient having massive ascites and bilateral lower leg edema. Colonoscopy showed a 3-cm lesion in the sigmoid colon and an edematous nonpapillary tumor was found by cystoscopy in the bladder. Histopathology analysis of the biopsies showed adenocarcinoma of colon and PUC of bladder. The diagnosis of PUC with peritoneal carcinomatosis was then confirmed by immunohistochemical stain. Conclusion: The diagnostic dilemmas of the unusual variant of urothelial malignancy, the origin of peritoneal metastasis, and its clinical impact are discussed in the present case. PMID:28207504

    2,5-Anhydromannitol decreases lactate formation and 3H2O formation from [5-3H]glucose in isolated rat hepatocytes metabolizing high concentrations of glucose. The inhibition of glycolysis is accompanied by a slight decrease in the cellular content of fructose-6-P and a more substantial decrease in the cellular content of fructose-1,6-P2, with no change in the content of glucose-6-P. The 3H2O release data and changes in hexosephosphate distribution indicate possible inhibitions at phosphofructokinase-1 and phosphoglucose isomerase. 2,5-Anhydromannitol also inhibits glycolysis in Ehrlich ascites cells, but the tumor cells, unlike hepatocytes, must be treated with 2,5-anhydromannitol prior to exposure to glucose to obtain the inhibition. The decrease in 3H2O formation from [5-3H]glucose and the metabolite pattern that results from the addition of low concentrations (less than or equal to 0.25 mM) of 2,5-anhydromannitol indicate an inhibition at phosphofructokinase-1 that cannot be attributed to a decrease in the cellular content of fructose-2,6-P2. Higher concentrations (greater than or equal to 0.5 mM) of 2,5-anhydromannitol cause a substantial decrease in the cellular content of ATP that is accompanied by decreases in the content of glucose-6-P and fructose-6-P and transient increases in fructose-1,6-P2. In Ehrlich ascites cells, 2,5-anhydromannitol is metabolized to 2,5-anhydromannitol mono- and bisphosphate. The inhibition of glycolysis caused by 2,5-anhydromanitol decreases with time, because the phosphorylated metabolites formed during the preliminary incubation in the absence of glucose are rapidly dephosphorylated during the incubation in the presence of glucose.

    Cancerous cells secrete alpha-N-acetylgalactosaminidase (NaGalase) into the blood stream, resulting in deglycosylation of serum vitamin D3-binding protein (known as Gc protein), which is a precursor for macrophage activating factor (MAF). Incubation of Gc protein with immobilized beta-galactosidase and sialidase generates the most potent macrophage activating factor (designated GcMAF). Administration of GcMAF to cancer-bearing hosts can bypass the inactivated MAF precursor and act directly on macrophages for efficient activation. Therapeutic effects of GcMAF on Ehrlich ascites tumor-bearing mice were assessed by survival time and serum NaGalase activity, because serum NaGalase activity was proportional to tumor burden. A single administration of GcMAF (100 pg/mouse) to eight mice on the same day after transplantation of the tumor (5 x 10(5) cells) showed a mean survival time of 21 +/- 3 days for seven mice, with one mouse surviving more than 60 days, whereas tumor-bearing controls had a mean survival time of 13 +/- 2 days. Six of the eight mice that received two GcMAF administrations, at Day 0 and Day 4 after transplantation, survived up to 31 +/- 4 days whereas, the remaining two mice survived for more than 60 days. Further, six of the eight mice that received three GcMAF administrations with 4-day intervals showed an extended survival of at least 60 days, and serum NaGalase levels were as low as those of control mice throughout the survival period. The cure with subthreshold GcMAF-treatments (administered once or twice) of tumor-bearing mice appeared to be a consequence of sustained macrophage activation by inflammation resulting from the macrophage-mediated tumoricidal process. Therefore, a protracted macrophage activation induced by a few administrations of minute amounts of GcMAF eradicated the murine ascites tumor.

    Objectives: With the development of sophisticated instruments for the isolation and elucidation of natural products structures from marine and freshwater organisms, major advances have been made in the discovery of aquatic derived therapeutics. Present investigations were carried out to evaluate cuttlefish (Sepia officinalis) ink extract (IE) and freshwater clam (Coelatura aegyptiaca) extract (CE) for their anticancer and antioxidant activities as compared to 5-flurouracil (5-Fu), in Ehrlich ascites carcinoma (EAC). Methods: Sixty female Swiss albino mice were divided into five groups (n = 12). All groups except group I received EAC cells (5 × 106 cells/mouse i.p.) and this was taken as the 0th day. Group I served as saline control (5 ml/kg 0.9% NaCl w/v p.o). Group II served as EAC control. Rats of groups III, IV and V received IE, CE (200 mg/kg body weight i.p.), and reference drug (5-Fu, 20 mg/kg body weight i.p.), respectively. Results: The reduction in tumor volume, packed cell volume, tumor cell counts and increase in median survival time and percentage increase in life span in treated animals were observed. There was a significant increase in RBC count; Hb content in treated animals and reduction in total WBC count. There was a significant decrease in AST, ALT, ALP and liver MDA levels and increase in GSH, SOD and NO levels were observed in all treated animals. Conclusion: Both IE and CE were effective in inhibiting the tumor growth in ascitic tumor models. The biochemical, antioxidants and histopathological studies were also supported their antitumor properties. PMID:26097537

    Granulocyte colony-stimulating factor (G-CSF)-producing pancreatic tumors are extremely rare. These tumors have an aggressive clinical course and no established treatment. Here, we report an autopsy case of G-CSF-production in pancreatic anaplastic carcinoma (PAC). A 72-year-old woman presented with a large pancreatic head mass and multiple liver metastases. Laboratory data showed leukocytosis (leukocyte count 113.3 × 10(3) /µL) and high serum G-CSF levels (441 pg/mL; normal range: <39.0 pg/mL). The ascitic fluid was submitted to our pathology laboratory at initial diagnosis. Cytopathology showed that smears from the ascitic fluid were highly cellular and contained numerous malignant cells, mainly in loose groupings. Occasional pseudoglandular formations and giant cells were also present. The malignant cells were round, and no spindle-shaped cells were visible. The nuclei were round to ovoid with coarsely granular chromatin and large prominent nucleoli. Upon immunocytochemistry, tumor cells were positive for G-CSF and vimentin; there was no E-cadherin expression. Histopathological examination of the tumor showed a mixed composition of adenocarcinomatous and sarcomatous regions. Upon immunohistochemistry, both components were positive for G-CSF. Few CD34-positive myeloblasts were observed in the bone marrow. Thus, we diagnosed this as a case of G-CSF production in PAC with leukocytosis. To the best of our knowledge, this is the first report on G-CSF expression immunocytochemically confirmed in PAC. Diagn. Cytopathol. © 2017 Wiley Periodicals, Inc.

    The intracellular synthesis and retention of polygammaglutamyl derivatives of methotrexate and their interactions with H/sub 2/ folate reductase was evaluated. Methotrexate polyglutamates were detected within 15 minutes in hepatocytes exposed to 1 microM methotrexate, and continued to accumulate for at least 60 minutes producing a large transmembrane gradient. These derivatives appeared to be preferentially retained within the cell. In studies with the Ehrlich ascites tumor accumulation of methotrexate polyglutamates was increased over 5-fold by the addition of 5 mM L-glutamine or L-glutamate and exhibited a positive correlation with the extracellular concentration of methotrexate. When Ehrlich ascites tumor cells were exposed to 10 microM methotrexate and 5 mM L-glutamine intracellular polyglutamates were detected within 10 minutes and their levels increased linearly over 4 hours. As these derivatives accumulated, there was a decline in intracellular methotrexate due at least in part to a replacement of methotrexate on H/sub 2/ folate reductase by polyglutamates and subsequent efflux of the previously bound methotrexate from the cell. When polyglutamate derivatives were in excess of the H/sub 2/ folate reductase binding capacity and extracellular methotrexate removed, methotrexate rapidly exited the cell whereas the majority of its metabolites were retained and eventually saturated the major portion of the enzyme. These studies indicate that (1) intracellular methotrexate is rapidly converted to polygammaglutamyl derivatives, (2) these metabolites effectively compete with methotrexate for binding sites on H/sub 2/ folate reductase, (3) these derivatives are retained within the cell more effectively than methotrexate, and (4) vincristine and probenecid may be potentially useful for selectively increasing methotrexate polyglutamates in tumor cells.

    Nitric oxide (NO) is a potent pulmonary vasodilator that modulates the pulmonary vasoconstriction and pulmonary hypertension (PH) triggered by bacterial lipopolysaccharide (LPS) in broilers. The amplitude and duration of the LPS-induced PH are markedly enhanced following pretreatment with N(omega)-nitro-L-arginine methyl ester (L-NAME), which inhibits NO synthesis by both the constitutive (endothelial) and inducible (inflammatory) forms of nitric oxide synthase (eNOS and iNOS, respectively). In the present study L-NAME and the selective iNOS inhibitor aminoguanidine (AG) were administered to differentiate between iNOS and eNOS as the primary source of NO that attenuates the pulmonary vascular response to LPS. Clinically healthy male progeny from ascites-susceptible and ascites-resistant lines were anesthetized, and their pulmonary artery was cannulated. The initial pulmonary arterial pressure (PAP) was recorded, then the broilers either remained untreated (control group) or were injected i.v. with AG. Ten minutes later all birds received an i.v. injection of LPS, followed 40 min later by an i.v. injection of L-NAME. When compared with untreated controls, AG neither increased the baseline PAP nor did it increase or prolong the PH response to LPS. The ascites-susceptible broilers maintained a higher PAP than the ascites-resistant broilers throughout the experiment, and the ascites-resistant broilers exhibited greater relative increases in PAP in response to LPS than did the ascites-susceptible broilers. Within 40 min after the LPS injection, PAP subsided to a level that did not differ from the respective preinjection value for each line. Injecting L-NAME reversed the decline in PAP, and within 5 min PAP returned to hypertensive levels approaching the maximum peak PH response to LPS. The absence of any impact of AG coupled with the profound response to L-NAME indicates that NO synthesized by eNOS rather than iNOS likely modulated the acute (within 1 h) PH elicited by

    Effects of dietary L-carnitine and coenzyme Q10 (CoQ10) at different supplemental ages on performance and some immune response were investigated in ascites-susceptible broilers. A 3 x 2 x 2 factorial design was used consisting of L-carnitine supplementation (0, 75, and 100 mg/kg), CoQ10 supplementation (0 and 40 mg/kg) and different supplemental ages (from day 1 on and from day 10 on). A total of 480 one-day-old Arbor Acre male broiler chicks were randomly allocated to 12 groups, every group had five replicates, each with eight birds. The birds were fed a corn-soybean based diet for six weeks. From day 10-21, all the birds were exposed to a low ambient temperature (12-15 degrees C) to increase the susceptibility to ascites. No significant effects were observed on growth performance by L-carnitine, CoQ10 supplementation, and different supplemental ages. Packed cell volume was significantly decreased by L-carnitine supplementation alone, and ascites heart index and ascites mortality were decreased by L-carnitine, CoQ10 supplementation alone, and L-carnitine + CoQ10 supplementation together (p < 0.05). Heart index of broilers was significantly improved by L-carnitine, CoQ10 supplementation alone during 0-3 week. Serum IgG content was improved by L-carnitine supplementation alone (p < 0.05), but lysozyme activity was increased by L-carnitine + CoQ10 supplementation together (p < 0.05). A significant L-carnitine by supplemental age interaction was observed in lysozyme activity. L-carnitine supplementation alone had no effects on the peripheral blood lymphocyte (PBL) proliferation in response to concanavalin A (ConA) and lipopolysaccharide, but supplemental CoQ10 alone and L-carnitine+ CoQ10 together decreased the PBL proliferation in response to ConA (p < 0.05). The present study suggested that L-carnitine + CoQ10 supplementation together had positive effects on some immune response of ascites-susceptible broilers, which might benefit for the reduction of broilers

    Experiments were carried out on noninbred male albino mice to assess the effects of varying doses of chalone-containing alcohol precipitates on mitotic activity and DNA synthesis in Ehrlich ascites tumor. Histological preparations of the tumor and small intestine were made by standard methods. Hydrolysis of the tumor in HCl was carried out before application of the nuclear photographic emulsion in order to prepare autoradiographs of the tumor. Tritium-labelled thymidine was injected as the radioactive marker.

    The reduction of a new series of tetrazolium salts to red fluorescent formazans by Ehrlich ascites tumor cells is described. The qualitative effect on this reaction of two cell surface-active compounds and of six exogenous electron carriers was investigated by varying the incubation conditions. After incubation of Ehrlich ascites cells with the new colourless, water soluble 5-cyan-2.3-ditolyltetrazolium salts, bright red water-insoluble formazan crystals on the cell surface can be observed under fluorescence microscopy. The production of formazan is enhanced by 12-0-tetradecanoyl-phorbol-13-acetate (TPA) or digitonin (DIG), two potent stimulators of oxygen consumption or by the electron carriers phenazine methosulphate (PMS), 1-methoxy-phenazine methosulphate (MPMS), meldola blue (MB), methylene blue (MTB), and 2.6-dichlorindophenol (DCIP). These results provide further evidence for the existence of redox enzymes bound to the plasma membrane of intact ascites cells and for a free radical mechanism of tetrazolium salt reduction. The fluorescence property of the new redox dyes offers the advantage of high sensitivity. Moreover, their greater homogeneity relative to the commonly used di-tetrazolium salts lowers the chances of misinterpretations due to impurities. The possible application of these new mono-tetrazolium salts to cytochemical investigations of oxidative metabolic reactions is discussed.

    The pharmacological properties of beta-adrenoceptors in rat ascites hepatoma cells were compared with those in normal rat liver cells which were cultured for 24 hr after collagenase digestion. Adenylate cyclases in the homogenates of cultured normal rat liver cells and rat ascites hepatoma cells, AH44, AH66, AH109A, AH130 and AH7974, were all activated by isoproterenol or NaF to different degrees. The enzyme in rat liver cells was activated by several beta 2-agonists but those in all hepatoma cells hardly responded. Furthermore, salbutamol, a beta 2-partial agonist, antagonized the cyclase activation by isoproterenol in AH130 cells. The Kact value of isoproterenol for the activation of adenylate cyclase in AH130 cells was smaller than that in rat liver cells. A comparison of the Ki values of beta-antagonists for the inhibition of isoproterenol-stimulated cyclase activity shows that while the Ki values of propranolol and butoxamine in AH130 cells were similar to those in rat liver cells, a significant difference was observed in the values for beta 1-selective antagonists between AH130 cells and rat liver cells. The Ki values of metoprolol and atenolol for AH130 cells were 137- and 90-fold lower, respectively, than for normal rat liver cells. From these findings, it is strongly suggested that beta-adrenoceptors in rat ascites hepatoma cells including AH130 cells have similar properties to the mammalian beta 1-receptor.

    The O-linked glycosylation of the main acidic high-molecular-weight glycoprotein from ascites fluid from patients with ovarian cancer were analyzed. The O-linked oligosaccharides were shown to consist of mainly highly sialylated core 1 and 2 structures with a smaller amount of sulfated core 2 structures. These structures were shown to be able to be further extended into small keratan sulfate (KS)-type oligosaccharides with up to four N-acetyllactosamine units. Proteomic studies of the acidic fraction of ascites fluid from patients with ovarian cancer showed that this fraction was enriched in proteoglycans. Among them, lumican, agrin, versican and dystroglycans were potential candidates, with threonine- and serine-rich domains that could carry a significant amount of O-linked glycosylation, including also the O-linked KS. Glycomic analysis using liquid chromatography (LC)-tandem mass spectrometry (MS/MS) also showed that the disialic acid NeuAc-NeuAc- was frequently found as the terminating structure on the O-linked core 1 and 2 oligosaccharides from one ascites sample. Also, a small amount of the epidermal growth factor (EGF)-associated O-linked fucose structure Gal-GlcNAc-Fucitol was detected with and without sialic acid in the LC-MS/MS analysis. Candidate proteins containing O-linked fucose were suggested to be proteoglycan-type molecules containing the O-linked fucose EGF consensus domain.

    Water accumulation in the interstitium (edema) and the peritoneum (ascites) of nephrotic patients is classically thought to stem from the prevailing low plasma albumin concentration and the decreased transcapillary oncotic pressure gradient. However, several clinical and experimental observations suggest that it might also stem from changes in capillary permeability. We addressed this hypothesis by studying the peritoneum permeability of rats with puromycin aminonucleoside-induced nephrotic syndrome. The peritoneum of puromycin aminonucleoside rats displayed an increase in the water filtration coefficient of paracellular and transcellular pathways, and a decrease in the reflection coefficient to proteins. It also displayed oxidative stress and subsequent activation of NF-κB. Scavenging of reactive oxygen species and inhibition of NF-κB prevented the changes in the water permeability and reflection coefficient to proteins and reduced the volume of ascites by over 50%. Changes in water permeability were associated with the overexpression of the water channel aquaporin 1, which was prevented by reactive oxygen species scavenging and inhibition of NF-κB. In conclusion, nephrotic syndrome is associated with an increased filtration coefficient of the peritoneum and a decreased reflection coefficient to proteins. These changes, which account for over half of ascite volume, are triggered by oxidative stress and subsequent activation of NF-κB.

    Recently, a small subset of T cells that expresses the B cell marker CD20 has been identified in healthy volunteers and in patients with rheumatoid arthritis and multiple sclerosis. The origin of these CD20-positive T cells as well as their relevance in human disease remains unclear. Here, we identified that after functional B cell/T cell interaction CD20 molecules are transferred to the cell surface of T cells by trogocytosis together with the established trogocytosis marker HLA-DR. Further, the presence of CD20 on isolated CD20+ T cells remained stable for up to 48h of ex vivo culture. These CD20+ T cells almost exclusively produced IFNγ (∼70% vs. ∼20% in the CD20− T cell population) and were predominantly (CD8+) effector memory T cells (∼60–70%). This IFNγ producing and effector memory phenotype was also determined for CD20+ T cells as detected in the peripheral blood and ascitic fluids of ovarian cancer (OC) patients. In the latter, the percentage of CD20+ T cells was further strongly increased (from ∼6% in peripheral blood to 23% in ascitic fluid). Taken together, the data presented here indicate that CD20 is transferred to T cells upon intimate T cell/B cell interaction. Further, CD20+ T cells are of memory and IFNγ producing phenotype and are present in increased amounts in ascitic fluid of OC patients. PMID:26137418

    The objective of this study was to investigate the effects of L-carnitine on growth performance, organ weight, biochemical parameters of blood, heart and liver, and ascites susceptibility of broilers at different ages reared under a low-temperature environment. A total of 420 1-d-old male Ross 308 broilers were randomly assigned to two dietary treatments with fifteen replicates of fourteen broilers each. Treatment diets consisted of L-carnitine supplementation at levels of 0 and 100 mg/kg. At 11-d of age, low temperature stress was used to increase ascites susceptibility. Blood, heart and liver samples were collected at different ages for analysis of boichemical parameters. The results showed that, there was no significant difference in growth performance with L-carnitine supplementation, but the mortality due to ascites was significantly decreased. Dietary L-carnitine supplementation significantly reduced heart index (HI) and ascites heart index (AHI) on d 21, lung index (LUI) on d 35 and liver index (LI) on d 42. The broilers fed diets containing L-carnitine had significantly lower red blood cell counts (RBC), hemoglobin (HGB) concentration and hematocrit (HCT) on d 42. Dietary L-carnitine supplementation significantly reduced malondialdehyde (MDA) content of heart tissue on d 21 and 35, and significantly increased total superoxide dismutase (T-SOD) and Glutathione peroxidase (GSH-Px) activity of the heart on d 21 and 42. L-carnitine supplementation significantly reduced serum triglyceride (TG) content on d 28 and 35 and serum glucose (GLU) on d 35 and 42, and significantly increased serum total protein (TP) and globulin (GLO) content on d 42. L-carnitine supplementation significantly enhanced liver succinodehydrogenase (SDH), malic dehydrogenase (MDH) and Na+-K+-ATPase activity on d 28, and tended to reduce the lactic acid (LD) level of liver on d 35 (p = 0.06). L-carnitine supplementation significantly reduced serum uric acid (UA) content on d 28, 35 and 42

    Intensive selection of broilers for faster growth and better feed efficiency resulted in greater susceptibility to metabolic disorders such as ascites syndrome, which is one of the major causes of mortality and economic loss in broiler industry. Whereas cool temperature is one of the primary triggers for ascites, early feed restriction (FDR) significantly alleviates its incidence and mortality. However, little is known about effects of FDR, cold environmental temperature and their interaction on physiological responses in broiler chickens. For this purpose, 320 one-day-old male broilers were divided into two treatment groups of Ad libitum (Ad) and feed restricted (FR) with eight pen replicates each. Chickens in FR group underwent feed access limitation from days 7 to 14 of age. On day 21 half of the birds (four pens) in each group exposed to the cold temperature (CT) and the other half (four pens) continued at normal temperature (NT). Average daily feed intake, average daily weight gain and feed conversion ratio (FCR) were measured at days 7, 14, 21, 28 and 42. At 39 and 46 days of age two chicks with a BW around the pen average were selected from each pen and slaughtered after collecting blood samples. Then, relative weight of internal organs and right ventricle weight per total ventricle weight (RV : TV) ratio were calculated. Compared with NT group, CT birds had higher daily feed intake and FCR (P<0.05) from day 28 to 42. Cumulative ascites mortality in CT chickens was higher (P<0.001) than NT chicks. Within the CT group, ascites mortality in FR chickens was reduced (P<0.001) to 1.25% compared with 8.75% in Ad chicks. Birds in CT group had significantly (P<0.05) thicker right ventricle and greater relative weight of heart, hematocrit and triiodothyronine concentration. However, none of these parameters were affected by FDR. Under cold stress conditions, FDR reduced activity of alanine aminotransferase and aspartate aminotransferase (P<0.05). Serum triglyceride

    The effect of methylglyoxal on the oxygen consumption of Ehrlich-ascites-carcinoma (EAC)-cell mitochondria was tested by using different respiratory substrates, electron donors at different segments of the mitochondrial respiratory chain and site-specific inhibitors to identify the specific respiratory complex which might be involved in the inhibitory effect of methylglyoxal on the oxygen consumption by these cells. The results indicate that methylglyoxal strongly inhibits ADP-stimulated alpha-oxo-glutarate and malate plus pyruvate-dependent respiration, whereas, at a much higher concentration, methylglyoxal fails to inhibit succinate-dependent respiration. Methylglyoxal also fails to inhibit respiration which is initiated by duroquinol, an artificial electron donor. Moreover, methylglyoxal cannot inhibit oxygen consumption when the NNN'N'-tetramethyl-p-phenylenediamine by-pass is used. The inhibitory effect of methylglyoxal is identical on both ADP-stimulated and uncoupler-stimulated respiration. Lactaldehyde, a catabolite of methylglyoxal, can exert a protective effect on the inhibition of EAC-cell mitochondrial respiration by methylglyoxal. We suggest that methylglyoxal possibly inhibits the electron flow through complex I of the EAC-cell mitochondrial respiratory chain.

    Transforming growth factor-{beta}1 (TGF-{beta}1) is a multifunctional growth factor that plays a role in cell proliferation, differentiation, extracellular matrix production, apoptosis, and cell motility. We show here that TGF-{beta}1 increased the invasiveness of MM1 cells, which are a highly invasive clone of rat ascites hepatoma cells. Both mRNA and protein levels of RhoC but not RhoA in TGF-{beta}1-treated MM1 cells increased. In parallel with this increase in expression, RhoC activity was induced by TGF-{beta}1 treatment. When RhoC was overexpressed in MM1 cells, the invasive capacity increased. The RhoC-overexpressing cells formed more nodules than did mock cells when injected into rat peritoneum. Furthermore, when RhoC expression was reduced by transfection with shRNA/RhoC, the invasiveness of MM1 cells decreased with concomitant suppression of RhoC expression. Thus, the induced expression of RhoC by TGF-{beta}1 in MM1 cells plays a critical role in TGF-{beta}1-induced cell migration.

    In this study, we report evidence of the damage effects of sonodynamic therapy (SDT) on a novel intracellular target, cytoskeletal F-actin, that has great importance for cancer treatment. Ehrlich ascites carcinoma (EAC) cells suspended in PBS were exposed to ultrasound at 1.34 MHz for up to 60s in the presence and absence of protoporphyrin IX (PPIX). To evaluate the polymeric state and distribution of actin filaments (AF) we employed FITC-Phalloidin staining. The percentage of cells with intact AF was decreased with 10-80 microM PPIX after ultrasonic exposure, while only few cells with disturbed F-actin were observed with 80 microM PPIX alone. The fluorescence intensity of FITC-Phalloidin labeled cells was detected by flow cytometry. The morphological changes of EAC cells were observed by scanning electron microscope (SEM). The nuclei were stained with Hoechst 33258 to determine apoptosis. Cytoskeletal F-actin and cell morphological changes were dependent on the time after SDT. Some cells suffered deformations of plasma membrane as blebs that reacted positively to FITC-Phalloidin at 2h after SDT treatment. Many of the cells showed the typically apoptotic chromatin fragmentation. The alterations were more significant 4h later. Our results showed that cytoskeletal F-actin might represent an important target for the SDT treatment and the observed effect on F-actin and the subsequent bleb formation mainly due to apoptosis formation due to the treatment.

    The objective of this study was to assess the effects of dietary supplementation with lipoic acid (LA) on broilers maintained at 2235 m above sea level with high risk to develop ascites syndrome (AS). A total of 2040 chicks were fed under commercial conditions with water and specific diets ad libitum during 7 weeks in two consecutive experiments. Mortality and indicators of performance and oxidative stress were compared weekly in broilers fed a basal diet plus 0, 10, 20, or 40 parts/10(6) LA. The effects of LA at 40 parts/10(6) were also studied during the initial 3 weeks or the last 4 weeks of the production cycle. Diets supplemented with 40 parts/10(6) of LA during 7 weeks significantly improved feed conversion, decreased general mortality and mortality attributable to AS, and lowered thiobarbituric acid reactive substances and hydroxyl radicals in liver, and increased total glutathione pool. Smaller doses or shorter periods of exposure to LA were partially effective. In conclusion, LA under our experimental conditions has a prophylactic action in broilers with high risk to develop AS due to oxygen availability limitation.

    2001-04-01

    By using a series of chemical inhibitors of mitochondrial respiration, a site-specific defect in the electron transport chain was identified in mitochondria obtained from broilers with pulmonary hypertension syndrome (PHS; ascites). Located at the succinate:ubiquinone oxido-reductase (Complex II:CoQ) interface, this defect would allow electrons to leak from the respiratory chain and consume oxygen by forming reactive oxygen species at a greater rate than in control mitochondria. Lower levels of the primary antioxidants, alpha- and beta-tocopherol, and glutathione (GSH) in PHS mitochondria confirmed the presence of oxidative stress. Respiration studies of PHS liver mitochondria also revealed disease-associated decreases in the respiratory control ratio (RCR, an index of electron transport chain coupling). Differences in the RCR as well as the adenosine diphosphate (ADP) to O ratio (an index of oxidative phosphorylation) between control and PHS mitochondria were accentuated by sequential additions of ADP to isolated mitochondria. In a second experiment, similar improvements in functional indices following sequential additions of ADP and responses to respiratory chain inhibitors were observed in liver mitochondria isolated from Single Comb White Leghorn (SCWL) males (resistant to PHS) similar to that observed in control broiler mitochondria in Experiment 1. The combined results indicate the presence of a site-specific defect at either Complex II, ubiquinone, or both in liver mitochondria obtained from broilers with PHS that may be responsible for the oxidative stress and mitochondrial dysfunction observed in this costly metabolic disease.

    Rat ascites hepatoma (AH) cells (10(6) cells/head) inoculated intraperitoneally into rats had host-killing ability (malignancy) in the order AH66F > AH44 > AH13 > AH7974 > AH109A > AH66 > AH130. The life span of the rats after inoculation closely correlated with the activity of cyclic AMP-dependent protein kinase (protein kinase A) in the tumor cells but not the activity of Ca2+/phospholipid-dependent protein kinase (protein kinase C). N-[2-[N-[3-(4-chlorophenyl)-1-methyl-2-propenyl]amino]ethyl]-5- isoquinoline-sulfonamide (H-87), a potent, selective inhibitor of protein kinase A, inhibited in vitro growth of these hepatoma cells with a similar potency and, intraperitoneally injected, prolonged the lives of rats bearing less malignant AH66 cells (with high protein kinase A activity) but did not affect the life span of rats bearing highly malignant AH66F cells (with low protein kinase A activity). On the other hand N-(2-methylpiperazyl)-5-isoquinolinesulfonamide (H-7), an inhibitor of protein kinase C, inhibited AH66F cells more than AH66 cells, but did not influence the life span of rats bearing either hepatoma. From these results it is deduced that protein kinase A may be important in the regulation of malignancy and in vivo proliferation of AH cells.

We herein report a successful conversion of unresectable to resectable disease using combination chemotherapy with trastuzumab. The patient was a 39-year-old woman with human epidermal growth factor receptor 2-positive gastric cancer with peritoneal, pulmonary and bilateral ovarian metastases. After 6 cycles of S-1 plus cisplatin with trastuzumab, followed by 15 cycles of intravenous and intraperitoneal paclitaxel with S-1 and trastuzumab, the pulmonary and peritoneal metastases exhibited complete response and no evidence of malignancy was found on diagnostic laparoscopy. We performed metastasectomy of the bilateral sizeable ovaries, followed by total gastrectomy. The patient had no recurrence for 16 months after the gastrectomy. Therefore, satisfactory response to systemic and intraperitoneal chemotherapy may convert unresectable to resectable disease, and primary tumor resection with ovarian metastasectomy may prolong survival. This combination chemotherapy has the potential of becoming a conversion therapy for gastric cancer with peritoneal metastases, even if ascites and ovarian metastases are extensive. PMID:28105352

    Irradiation of Ehrlich ascites carcinoma (EAC) cells in the presence of pheomelanin, i.e., red hair melanin (RHM), has been reported to produce extensive cell lysis. Irradiation in the presence of eumelanin, i.e., black hair melanin (BHM), or irradiation in the absence of either type of melanin did not produce this effect. We observed that RHM particles penetrated the cell membrane without apparent structural damage to the cell or the cell membrane. Irradiation of the cells in the absence of melanin did not produce any changes in the ultrastructure of the cells. Incubation of the cells in the dark in the presence of RHM produced only minor structural, mainly cytoplasmic changes. Irradiation of the cells in the presence of RHM produced extensive ultrastructural changes prior to complete cell lysis; these changes were more severe than the effects of incubation of the cells in the dark in the presence of RHM. When the cells incubated in the dark or irradiated in the presence of latex particles or either one of the eumelanins particles, viz. BHM or synthetic dopa melanin, these particles did not penetrate into the cells or produce any ultrastructural changes. These particles were in fact not even ingested by the cells.

    1. The total lipid was extracted from BP8/C3H ascites-sarcoma cells with acetone, light petroleum, pyridine and chloroform–methanol successively. Each extract was treated with mild alkali. The alkali-stable lipids from the pyridine and chloroform–methanol extracts, which included the glycolipids, were fractionated on silicic acid and silica gel G columns. 2. The total yield of glycolipid was about 60 mg./100 g. dry wt. of tumour cells, about 0·4% of the total lipid. Four classes of glycolipid were isolated and characterized as ceramide monohexoside (G1), ceramide dihexoside (G2), ceramide trihexoside (G3) and ceramide hexosaminyltrihexoside (G4). 3. G1, G2, G3 and G4 constituted 55, 21, 9 and 15% of the total glycolipid respectively. 4. G1 was a mixture of ceramide glucoside (70%) and ceramide galactoside. 5. The general structures of the oligosaccharide moieties of G2, G3 and G4 were elucidated by partial acid hydrolysis of the glycolipids with water-soluble polystyrenesulphonic acid. G2 was mostly ceramidelactoside with about 10% of ceramide galactosylgalactoside. G3 and G4 were probably a ceramide digalactosylglucoside and a ceramide N-acetylgalactosaminylgalactosylgalactosylglucoside respectively. 6. The fatty acid compositions of the glycolipids were very similar; lignoceric acid and nervonic acid were the major components and all contained monohydroxy acids in proportions varying from 10 to 25% of the total acids.

    Background M1 macrophages target tumor cells. However, many tumors produce anti-inflammatory cytokines, which reprogram the anti-tumor M1 macrophages into the pro-tumor M2 macrophages. We have hypothesized that the problem of pro-tumor macrophage reprogramming could be solved by using a special M3 switch phenotype. The M3 macrophages, in contrast to the M1 macrophages, should respond to anti-inflammatory cytokines by increasing production of pro-inflammatory cytokines to retain its anti-tumor properties. Objectives of the study were to form an M3 switch phenotype in vitro and to evaluate the effect of M3 macrophages on growth of Ehrlich ascites carcinoma (EAC) in vitro and in vivo. Material/Methods Tumor growth was initiated by an intraperitoneal injection of EAC cells into C57BL/6J mice. Results 1) The M3 switch phenotype can be programed by activation of M1-reprogramming pathways with simultaneous inhibition of the M2 phenotype transcription factors, STAT3, STAT6, and/or SMAD3. 2) M3 macrophages exerted an anti-tumor effect both in vitro and in vivo, which was superior to anti-tumor effects of cisplatin or M1 macrophages. 3) The anti-tumor effect of M3 macrophages was due to their anti-proliferative effect. Conclusions Development of new biotechnologies for restriction of tumor growth using in vitro reprogrammed M3 macrophages is very promising. PMID:28123171

    AIM: To report the incidence and potential risk factors of small-volume chylous ascites (SVCA) following laparoscopic radical gastrectomy (LAG). METHODS: A total of 1366 consecutive gastric cancer patients who underwent LAG from January 2008 to June 2011 were enrolled in this study. We analyzed the patients based on the presence or absence of SVCA. RESULTS: SVCA was detected in 57 (4.17%) patients, as determined by the small-volume drainage (range, 30-100 mL/24 h) of triglyceride-rich fluid. Both univariate and multivariate analyses revealed that the total number of resected lymph nodes (LNs), No. 8 or No. 9 LN metastasis and N stage were independent risk factors for SVCA following LAG (P < 0.05). Regarding hospital stay, there was a significant difference between the groups with and without SVCA (P < 0.001). The 3-year disease-free and overall survival rates of the patients with SVCA were 47.4% and 56.1%, respectively, which were similar to those of the patients without SVCA (P > 0.05). CONCLUSION: SVCA following LAG developed significantly more frequently in the patients with ≥ 32 harvested LNs, ≥ 3 metastatic LNs, or No. 8 or No. 9 LN metastasis. SVCA, which was successfully treated with conservative management, was associated with a prolonged hospital stay but was not associated with the prognosis. PMID:25741151

    Cisplatin (CP) is a widely used cytotoxic agent against cancer, and high doses of CP have been known to cause nephrotoxicity and hepatotoxicity. Some reports claim that antioxidants can reduce CP-induced toxicity. This study investigated the hepatoprotective, nephroprotective, and antioxidant activity of Urtica dioica L methanolic extract (UDME) against CP toxicity in Erhlich ascites tumor (EAT)-bearing mice. Levels of serum hepatic enzymes, renal function markers, and oxidant/antioxidant parameters of liver tissue were measured. Mice were inoculated with EAT on day 0 and treated with nothing else for 24 hours. After a single dose of CP administration on day 1, the extract was given at the doses of 50, 100, 200, and 400 mg/kg body weight daily during 6 days. Almost all doses of UDME performed a significant (P < 0.05) preventive role against CP toxicity by decreasing aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, blood urea nitrogen, creatinine, lipid peroxidation, protein oxidation levels, and myeloperoxidase activity, as well as increasing reduced glutathione content, superoxide dismutase, catalase, glutathione S-transferase, and glutathione peroxidase activities. This suggests that UDME has a protective capacity and antioxidant activity against CP toxicity in EAT-bearing mice, probably by promoting antioxidative defense systems.

    This study was concerned with the role of copper (Cu) and Cu-metallothionein (Cu-MT) in oxidative stress. Hydrogen peroxide (H(2)O(2))-induced oxidative injury was examined in Ehrlich ascites tumour cells isolated from host mice pretreated with 0, 1 or 2mg of CuSO(4) (ip) 24h earlier. Control Ehrlich cells contained low levels of Cu and Cu treatment produced dose-related increases in cellular Cu and Cu-MT levels and corresponding increases in sensitivity to oxidative toxicity of H(2)O(2) (LC(50), cell blebbing, lipid peroxidation, GSH depletion, and increase in intracellular free [Ca(2+)](i)). Hydrogen peroxide treatment also resulted in the oxidation of MT thiolates, reduction in the binding of Cu to MT resulting in translocation of Cu to other subcellular sites. d-penicillamine, a Cu-chelating agent, obliterated the sensitization effect of Cu-pretreatment and reduced the redistribution of MT-bound Cu, suggesting the participation of Cu ions derived from MT in promoting oxidant stress. Additional experiments with desferoxamine and mannitol have revealed the involvement of a Cu-dependent Fenton reaction in the mediation of the prooxidative effect of Cu-MT. These data suggest that cells with high levels of Cu-MT may be particularly susceptible to oxidative stress.

    Bioflavonoids are plant compounds touted for their potential to treat or prevent several diseases including cancer caused by various stress conditions. Galangin (4H-1-Benzopyran-4-one, 3, 5, 7-trihydroxy-2-phenyl-), a flavonoid, is a polyphenolic compound found primarily in medicinal herb, Alpinia galanga. This study aims to demonstrate the galangin as a pharmacological lead compound using in vitro, in vivo, and in silico model targeting specific cancer condition and proteins. The proliferation of MCF-7 and Ehrlich ascites carcinoma (EAC) cells was significantly inhibited with an IC₅₀ of 34.11 and 22.29 μg/ml, respectively. In an animal model system, galangin has inhibited the tumor growth by 73.51% ± 4.742 in EAC-induced Swiss Albino mice with no evidences of mortality as compared to standard drug, 5-fluorouracil. The effectiveness of galangin is proven in an animal system suggesting its pharmacokinetics behavior in an animal model which is also complemented by outcome of in silico analysis with more than 88 % of human intestinal absorption and significant Caco-2 cell, MDCK cell, and skin permeability as predicted by in silico methods. Galangin was docked against 19 different proteins involved in tumorogenesis and apoptosis; the energetic analysis indicates that it exhibits higher predicted binding free energy of -12.7 kcal/mol with Bcl-xL protein.

    A single injection of irradiated Ehrlich ascites tumor (EAT) cells induces immunity in normal mice but fails to do so in T-cell-deficient-thymectomized, lethally irradiated, bone marrow-reconstituted (TIR) mice. TIR mice injected with normal syngeneic T cells develop an immune response to EAT when injected with irradiated EAT cells and reject a subsequent tumor cell challenge. In the present studies allogeneic T cells were unable to protect against EAT in TIR recipients even if harvested from donors tolerant to the recipient's transplantation antigens and injected into the TIR mice tolerant to the transplantation antigens of the injected T cells. Tolerance was produced by establishing long-term radiation chimeras of the P ..-->.. F/sub 1/ type. Semiallogeneic T cells also failed to afford protection against EAT in TIR recipients. Whereas tolerance to other parental-strain transplantation antigens did not reverse the inability of parental T cells (cells from P ..-->.. F/sub 1/ chimeric donors) to protect against EAT in F/sub 1/ TIR mice, it did enable F/sub 1/ T cells to afford protection in P ..-->.. F/sub 1/ TIR mice.

    Ehrlich ascites tumor cells were permeabilized using low concentrations of digitonin, 8 micrograms/10(6) cells. Permeabilization was monitored by the assay of lactate dehydrogenase released into the incubation medium and of hexokinase partially bound to mitochondria. Integrity of the cellular organelles was unaffected as determined by assay of the mitochondrial enzyme glutamate dehydrogenase. Cells were stained with rhodamine 123 as a mitochondrial specific dye and propidium iodide/mithramycin as DNA specific dyes. The green fluorescence of bound rhodamine 123 versus red fluorescence of DNA in individual cells was analysed by dual parameter flow cytometry. Incubation of cells with inhibitors of mitochondrial energy metabolism, such as, potassium cyanide and carbonyl cyanide m-chlorophenylhydrazone abolished binding of rhodamine 123. Flow cytometric data allowed a correlation between cell position in the mitotic cycle with total mitochondrial activity. In addition, comparison of the characteristics of propidium iodide and ethidium bromide staining further elucidated the molecular basis of the staining with the positively-charged fluorescent dye rhodamine 123.

    A reduction in effective (nonportal) plasma volume is considered the basis for renal sodium retention, a spontaneous reduction in glomerular filtration rate (GFR), and a fall in GFR occurring during drug-induced diuresis in patients with cirrhosis and ascites. In the present study the concept of a reduced effective plasma volume in cirrhosis is challenged by two lines of evidence, even though effective plasma volume itself could not be measured. (a) Total plasma volume failed to rise in 10 patients with the spontaneous loss of ascites, the appearance of sodium in the urine, and a rise in GFR. Portal pressure remained constant in these patients as ascites left, suggesting that effective plasma volume had not increased while portal plasma volume decreased. (b) Reduction of GFR could not be prevented in five patients with cirrhosis and ascites while total plasma volume was prevented from falling with albumin infusions during drug-induced diuresis. Reduction of GFR during drug-induced diuresis in 15 patients with cirrhosis and ascites was completely reversed with saline infusion despite continued diuresis with the identical drugs, excluding drug nephrotoxicity as the cause for the reduced GFR. The ascites of cirrhosis might no longer be regarded as a cause of effective plasma volume contraction, stimulating renal sodium retention and a reduction in GFR. More likely, this form of ascites is a result of plasma volume expansion and sodium retention. The causes for renal sodium retention and a spontaneous reduction in GFR remain unknown. The cause for a fall in GFR during drug-induced diuresis also remains unknown, but effective plasma volume contraction and drug nephrotoxicity seem excluded. Images PMID:5771197

    Ascites syndrome (AS) still has an unacceptably high incidence rate in both humans and animals although there have been many studies on AS. To continue our previous pathological and biochemical investigation on the underlying mechanisms of AS incidence in broiler chickens, cutting-edge technologies including RNA-seq and metabolimics were used by directly comparing AS chickens and healthy controls. The RNA-seq analysis in the liver identified 390 differentially expressed genes (DEGs), among which 212 genes were up-regulated and 178 genes were down-regulated in the AS group compared to the control. For the down-regulated DEGs, further gene ontology (GO) analysis suggested that lipid metabolism, cell differentiation, enzyme linked receptor protein signaling pathway and steroid biosynthesis pathway were significantly enriched. For up-regulated DEGs, the cholesterol metabolic process has the lowest p value (0.000966) of fold enrichment while the cholesterol biosynthetic process has the highest fold enrichment (46.67). The metabolomic analysis of serum revealed statistically significant changes in the concentrations of LysoPC(20 : 4), LysoPC(16 : 0), LysoPC(18 : 0), LysoPC(18 : 1), LysoPC(18 : 2), PC(14 : 1/20 : 1), PC(20 : 4/18 : 0), PC(14 : 1/22 : 1), dihydroxyacetone, indoleacrylic acid, ursodeoxycholic acid, l-valine, and l-tryptophan. The integrative analysis of transcriptome and metabolome indicated that two biological pathways of tryptophan biosynthesis and metabolism, and glycerophospholipid metabolism may contribute to the induction of AS in broilers. These findings have provided novel insights into our understanding of molecular mechanisms of AS incidence in broilers.

    Ascites syndrome (AS), also known as pulmonary artery hypertension, remains a challenging disease that severely affects both humans and broiler chickens. Pulmonary artery remodeling presents a key step in the development of AS. In this study, we obtained pulmonary artery tissues from broilers with and without AS to perform miRNA sequencing analysis, miRNA-mRNA association analysis and pathological examinations. 29 significantly differentially expressed miRNAs were found both in known and novel miRNAs with 18 up-regulated and 11 down-regulated miRNAs. Their predicted potential targets were involved in a wide range of functional clusters as indicated via GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) analyses. The upregulation of miR-155, miR-23b-3p, miR-146b-5p and miR-146b-3p were found closely associated with the pathogenesis of pulmonary artery remodeling in AS progression. The association analysis for the miRNAs-mRNAs showed that these 29 significantly differentially expressed miRNAs regulate 162 differentially expressed target genes. Among them, 20 miRNAs correlated with 18 predicted target genes that appear to be involved in pulmonary artery remodeling, mainly in three broad physiological processes: the hypoxia sensing response (HIF1α, NHE1, STAT5 and STAT3), endothelial permeability dysfunction (CD44, TRAF2, CDK2AP1, LZTFL1, JAZF1, PEBP1, LRP1B, RPS14 and THBS2) and inflammation (MEOX2, STAT5, STAT3, IRF8, MAP3K8, IL-1BETA and TNFRSF1B). Pathological pulmonary artery remodeling in the AS broilers was consistently observed in the present study. Taken together, the current analysis further illuminates the molecular mechanism of pulmonary artery remodeling underlying AS progression.

    Recently, a lectin was purified from the potato cultivated in Bangladesh locally known as Sheel. In the present study cytotoxicity of the lectin against Ehrlich ascites carcinoma (EAC) cells was studied by MTT assay in vitro in RPMI-1640 medium and 8.0-36.0 % cell growth inhibition was observed at the range of 2.5-160 μg/ml protein concentration when incubated for 24 h. The lectin-induced apoptosis in EAC cells was confirmed by fluorescence and optical microscope. The apoptotic cell death was also confirmed by using caspase inhibitors. Cells growth inhibition caused by the lectin (36 %) was remarkably decreased to 7.6 and 22.3 % respectively in the presence of caspase-3 and -8 inhibitors. RT-PCR was used to evaluate the expression of apoptosis-related genes Bcl-X, p53, and Bax. An intensive expression of Bcl-X gene was observed in untreated control EAC cells with the disappeared of the gene in Sheel-treated EAC cells. At the same time, Bax gene expression appeared only in Sheel-treated EAC cells and the expression level of the p53 gene was increased remarkable after the treatment of EAC cells with the lectin. The lectin showed strong agglutination activity against EAC cells. Flow cytometry was used to study the cell cycle phases of EAC cells and it was observed that the lectin arrested the G2/M phase. In conclusion, Sheel lectin inhibited EAC cells growth by inducing apoptosis.

    A study was made to determine the effectiveness of treating tumor-injected mice with verapamil, a calcium antagonist, and hyperthermia. The co-treatment reduced the incidence of tumors in animals injected with Meth A solid cells. It was shown that the decrease in tumors corresponded to increases in natural killer (NK) cell activity measured in a /sup 51/Cr release assay, in the amount of anti-Meth A antibody measured in an immunofluorescence assay, and a decrease in the amount of intra-tumor cyclic AMP measured by radioimmunoassay in co-treated compared to untreated sarcoma-injected animals. A role of the immune system for mediating the prevention of sarcoma growth was indicated by Winn assays. Splenocytes sensitized in vivo against Meth A solid cells for 14 days exhibited an enhanced cytotoxic activity against syngeneic target cells compared to untreated tumor-sensitized splenocytes following heat-drug co-treatment. It was established that the stimulation of cytotoxic T cells against a histocompatibility antigen (H-2/sup d/) present on Meth A sarcoma cells resulted in tumor cell lysis. Animals bearing established Meth A solid sarcomas did not manifest tumor regressions following the administration of co-treatment alone or the adoptive transfer of co-treated tumor-sensitized splenocytes. The growth of Meth A ascites and Meth A ascites-derived solid sarcomas, unlike Meth A solid cell tumors, were not prevented in Winn assays. Additionally, the lifespan of animals injected with Meth A ascites cells was reduced by 50% compared to animals injected with Meth A solid sarcoma cells.

    Experiments were carried out using various levels of sodium (Na+) from NaCl or NaHCO3 to determine: 1) the level of Na+ required to induce ascites alone or in combination with cold temperature and 2) the effect of Na+ on weight gain and fat deposition in broiler chickens. In experiment 1, there were no cases of ascites using levels of Na+, from NaCl at 0.14% to 0.44% in the feed from day 3 or using added Na+, from NaCl at 0.0% to 0.12% in the water from day 3 with a level of 0.14% in the feed. There was no significant difference in 21 or 42 day body weight, feed conversion, or right ventricle:total ventricle (RV:TV) ratio between treatment groups. Day 3 to 4 body weight gains were significantly increased in all treatment groups with added Na+ (p less than 0.01). In experiment 2, with levels of added Na+, from NaCl, at 0.0% to 0.12% in the water with a level of 0.20% in the feed there were two cases of ascites, one at day 7 and one at day 40 at the 0.12% level. There were no significant differences in body weight at days 21 or 42 or in the RV:TV ratios between groups. Feed conversions were improved (p less than 0.01) with the lowest and highest levels of Na+ and a significant increase in day 3 to 4 body weight gain, with increasing Na+ in all treatment groups, was observed.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1423057

    Introduction Patients with chronic liver diseases are usually thin as a result of hypermetabolism and malnutrition expressed by reduced levels of leptin and impairment of other adyponectins such as visfatin. Aims We evaluated the metabolic and inflammatory effects of intravenous high-dose furosemide plus hypertonic saline solutions (HSS) compared with repeated paracentesis and a standard oral diuretic schedule, in patients with cirrhosis and refractory ascites. Methods 59 consecutive cirrhotic patients with refractory ascites unresponsive to outpatient treatment. Enrolled subjects were randomized to treatment with intravenous infusion of furosemide (125–250mg⁄bid) plus small volumes of HSS from the first day after admission until 3 days before discharge (Group A, n:38), or repeated paracentesis from the first day after admission until 3 days before discharge (Group B, n: 21). Plasma levels of ANP, BNP, Leptin, visfatin, IL-1β, TNF-a, IL-6 were measured before and after the two type of treatment. Results Subjects in group A were observed to have a significant reduction of serum levels of TNF-α, IL-1β, IL-6, ANP, BNP, and visfatin, thus regarding primary efficacy endpoints, in Group A vs. Group B we observed higher Δ-TNF-α, Δ-IL-1β, Δ-IL-6, Δ-ANP, Δ-BNP, Δ-visfatin, Δ-Leptin at discharge. Discussion Our findings underline the possible inflammatory and metabolic effect of saline overload correction in treatment of cirrhosis complications such as refractory ascites, suggesting a possible role of inflammatory and metabolic-nutritional variables as severity markers in these patients.

    Ascites cells were labeled by intraperitoneal injection of [3H]cholesterol and aortic smooth muscle cells by addition of [3H]cholesterol to the serum component of the culture medium. The release of cholesterol from cells into a serum-free medium supplemented with the various "acceptors" was studied using ascites cells in suspension and aortic smooth muscle cells in a multilayer culture. Unfractionated human high-density apolipoprotein was somewhat more effective in the removal of labeled cellular free cholesterol, in both cell types, than apolipoprotein derived from rat high-density lipoprotein. Following separation of human high-density apolipoprotein into four fractions by Sephadex chromatography, the effect of each fraction on the removal of cellular cholesterol from ascites cells was studied. The individual fractions had a lower capacity for cholesterol removal than the original unfractionated high-density apolipoprotein and the lowest activity was detected in Fraction II which comprised 75% of the total apolipoprotein. The effectiveness to remove cholesterol could be restored to all the fractions, as well as enhanced, by addition of sonicated suspensions of lecithin or sphingomyelin, which by themselves promoted a more limited removal of cellular cholesterol. Negatively stained preparations of mixtures of the four fractions and sonicated dispersion of lecithin were shown to consist of vesicles and discs of various sizes. Addition of the apolipoprotein fractions (especially Fractions II and IV) to sonicated dispersion of sphingomyelin resulted in a pronounced formation of discs which showed a high tendency towards stack formation. Mixtures of Fraction II and lecithin or sphingomyelin were effective in the release of cellular cholesterol from multilayers of aortic smooth muscle cells in culture. These results show the feasibility of net removal of cholesterol from cells which grow in a form resembling a tissue and thus provide a model to study the role of

    Vitamin D3-binding protein (DBP; human DBP is known as Gc protein) is the precursor of macrophage activating factor (MAF). Treatment of mouse DBP with immobilized beta-galactosidase or treatment of human Gc protein with immobilized beta-galactosidase and sialidase generated a remarkably potent MAF, termed DBPMAF or GcMAF, respectively. The domain of Gc protein responsible for macrophage activation was cloned and enzymatically converted to the cloned MAF, designated CdMAF. In Ehrlich ascites tumor-bearing mice, tumor-specific serum alpha-N-acetylgalactosaminidase (NaGalase) activity increased linearly with time as the transplanted tumor cells grew in the peritoneal cavity. Therapeutic effects of DBPMAF, GcMAF, and CdMAF on mice bearing Ehrlich ascites tumor were assessed by survival time, the total tumor cell count in the peritoneal cavity, and serum NaGalase activity. Mice that received a single administration of DBPMAF or GcMAF (100 pg/mouse) on the same day after transplantation of tumor (1 x 10(5) cells) showed a mean survival time of 35 +/- 4 days, whereas tumor-bearing controls had a mean survival time of 16 +/- 2 days. When mice received the second DBPMAF or GcMAF administration at day 4, they survived more than 50 days. Mice that received two DBPMAF administrations, at days 4 and 8 after transplantation of 1 x 10(5) tumor cells, survived up to 32 +/- 4 days. At day 4 posttransplantation, the total tumor cell count in the peritoneal cavity was approximately 5 x 10(5) cells. Mice that received two DBPMAF administrations, at days 0 and 4 after transplantation of 5 x 10(5) tumor cells, also survived up to 32 +/- 4 days, while control mice that received the 5 x 10(5) ascites tumor cells only survived for 14 +/- 2 days. Four DBPMAF, GcMAF, or CdMAF administrations to mice transplanted with 5 x 10(5) Ehrlich ascites tumor cells with 4-day intervals showed an extended survival of at least 90 days and an insignificantly low serum NaGalase level between days 30 and 90.

    Mouse Ehrlich ascites carcinoma (EAC) cells proved to be a semipermissive substrate for in vivo cultivation of adenovirus 5 (Ad5) and SV40. The multiplication of SV40 in EAC cells was facilitated by the coinfection with Ad5. As demonstrated by ID and EID reactions, the virus progens isolated at the first passage after the mixed infection of EAC cells with Ad5 and SV40 possess an antigenic mosaic with fractions characteristic of the parental viruses and of the cell substrate in which they had cultivated in vitro and in vivo. The progens gave positive seroneutralization and complement fixation reactions only with antiserum to SV40.

    Les tumeurs de Krukenberg (TK) se définissent comme des métastases ovariennes d'un cancer, le plus souvent digestif. Elles représentent 5 à 15% des tumeurs malignes ovariennes. Notre objectif était de décrire les caractéristiques épidémiologiques, diagnostiques, thérapeutiques et évolutives. Nous rapportons deux observations de tumeur de Krukenberg découvertes à l'occasion de l'exploration d'une ascite fébrile.Il s'agit de deux patientes multipares âgées respectivement de 32 ans et 50 ans. Les signes d'appel étaient essentiellement digestifs. La découverte de ces métastases ovariennes était survenue à distance des foyers primitifs. L'atteinte des ovaires était bilatérale dans le premier cas et unilatérale droite dans le second cas. Le diagnostic est apporté par la tomodensitométrie abdominopelvienne dans les deux cas. La fibroscopie œsogastroduodénale avait permis de retrouver le foyer primitif respectivement sous forme d'un processus bourgeonnant et d'un ulcère en position antrale avec des stigmates d'hémorragies. L'examen anatomopathologique des biopsies réalisées mettait en évidence un adénocarcinome tubuleux moyennement différencié de l'estomac avec composante mucineuse dans la première observation et un adénocarcinome de type intestinal moyennement différencié dans la seconde. Le traitement chirurgical confirme le diagnostic histologique. Dans notre série, le traitement n'a pu être que symptomatique en raison de l'existence constante d'une carcinose péritonéale et de l'altération profonde de l’état général. Les deux patientes ont été confiées à l'institut de cancérologie pour une chimiothérapie palliative. La première est décédée 1 mois après. La tumeur de Krukenberg est une maladie rare. Le diagnostic est facilité par la radiologie et confirmé par l'histologie. Son pronostic demeure encore très sombre. Le seul espoir réside dans les mesures préventives. PMID:26587120

    In order to explain the biochemical mechanisms associated with deteriorating heart function in broiler chickens, this study compared myocardial high energy phosphate substrates in leghorns, feed restricted (Broilers-Res) broilers, ad libitum fed broilers (Broilers-AL), and in broilers that developed heart failure and ascites. The profile of adenine nucleotide content in the heart tissue did not differ between leghorns and Broilers-Res, but there were significant differences among Broilers-Res, Broilers-AL, and broilers with ascites. During intensive growth periods, leghorns and Broilers-Res showed increasing trends in heart ATP levels, whereas in fast growing broilers the heart ATP declined (p<0.021). ATP:ADP and ATP:CrP ratios increased with age in both leghorn and Broilers-Res, declined in fast growing broilers, and were the lowest in broilers that developed heart failure. The changes in heart high energy phosphate profile in broilers suggest that the energy demand of the heart during a rapid growth phase may exceed the bird's metabolic capacity to supply adequate levels of high energy phosphate substrate. The insufficiency of energy substrate likely contributes to the declining heart rate. In some individuals this may lead to impaired heart pump function, and in more severe cases may progress to heart pump failure.

    Forty four patients with refractory ascites due to chronic liver diseases that fulfilling the inclusion criteria of selection were divided into 2 groups. The first group (GI, n=24) was subdivided into 2 subgroups according to degree of liver condition; GIa (n=11) with Child-Pugh class B and GIb (n=13) with early class C. The patients were subjected to P-V shunt (Denver group). Similarly, patients in the second group (GII, n=20) were divided into 2 subgroups GIIa (n=10) & GIIb (n=10) respectively and treated by the repeated tapping and albumin infusion (control group). Postoperative results revealed a significant increase in urine out put (P<0.001), decrease in abdominal girth (P<0.01) and body weight (p<0.01) with more patients fitness and satisfaction than in controls. Postoperative complications were more in GIb. Ascites recurrence occurred in 3 (23%) patients in GIb due to severe infection (2 cases) and irreversible shunt obstruction (1 case) and without recurrence in GIa. So, Denver P-V shunt offers a good palliation in such patients, but its use is more justified in selected cases.

    Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings. PMID:26339267

    The heat produced by Ehrlich ascites carcinoma cells was measured microcalorimetrically to investigate the characteristics of the energetics of these cells. 2,4-Dinitrophenol and other inhibitors were used to obtain the standard thermograms. The heat level of starved Ehrlich ascites carcinoma cells (endogenous) was almost constant and linear and depended on the cell number used in the experiments (about 1 cal/1 X 10(8) cells/hr). The endogenous heat generation was suppressed strongly by potassium cyanide but not by iodoacetic acid or 2,4-dinitrophenol. On the other hand, heat evolution was directly related to the amount of glucose added to the medium but not to the number of cells (19 cal/mmol of glucose). The addition of iodoacetic acid markedly suppressed heat generation, but potassium cyanide did not. In contrast, glucose with dinitrophenol increased heat production markedly to about 10% higher than that of the control, possibly due to the uncoupled energy from oxidative phosphorylation. Malonic acid (1 mM) suppressed slightly the endogenous heat but caused a 15% reduction in exogenous heat. The amount of heat produced by the addition of glucose (19 cal/mmol) was equivalent to 40% of the theoretical value of energy released through glycolysis (47 cal/mmol). Thus, the heat produced by exogenous glucose appears to be mainly dependent on glycolysis.

    A hypothesis that the ionic composition of drinking water might affect development of the ascites syndrome in broilers was investigated in two trials. The first trial comprised four groups of 650 male chicks. A control treatment was normal tap water and the other three treatments comprised the addition to the tap water of 1,000 mg/L sodium as NaCl, 5,000 mg/L NH4Cl, or 5,000 mg/L KHCO3, supplied from age 2 to 47 d. At Day 28, equally sized subsets of these groups were moved to individual cages, where they received a severe exposure to ambient cold. The development of the ascites syndrome was monitored by measurements of hematocrit and arterial blood oxygen saturation (PaO2) by oximetry, body weight, and examination of dead birds for cause of death. Mortality from ascites in cold-exposed birds from Days 28 to 47 was 28, 48, 40, and 16% in the tap water, NaCl, NH4Cl, and KHCO3 groups, respectively; only the NaCl mortality was significantly different from the tap water mortality. The KHCO3 treatment increased PaO2 (compared with tap water treatment) at Day 28 by 5.5% and at Day 35 by 10.5%, but not at Day 42. The KHCO3 caused a reduction in body weight, which was 13% less than the tap water group at Day 42, probably due to a chronic toxicity. The second trial specifically examined the same parameters with lower water levels of KHCO3 (3,000 and 1,000 mg/L), in comparison to a 10% feed restriction protocol, in order to clarify whether the increased PaO2 was due to a specific effect of the KHCO3 or was a metabolic manifestation of a reduced growth rate. The 3,000 mg/L KHCO3 treatment had no effect on PaO2, but the 1,000 mg/L treatment augmented PaO2 by 5.3% at Day 35 (but not at Days 28 or 42), without reducing the final body weight. The feed restriction group showed an elevated PaO2 of 5.4% at Day 35 (but not at Days 28 or 42), with no reduction in the final body weight. The inclusion of 1,000 mg/L of KHCO3 into the drinking water of broilers or a temporary 10% feed

    Extracellular vesicles (EVs), including endosome-derived nanovesicles (exosomes), are involved in cell–cell communication. Through transfer of their molecular contents, extracellular nanovesicles can alter the function of recipient cells. Due to these characteristics, EVs have shown potential as a new alternative for cancer immunotherapy. Tumor exosomes isolated from malignant ascites can activate dendritic cells, thereby priming the immune system to recognize and kill cancer cells. However, a suppressive role on tumor immune response has also been reported, suggesting that the neoplastic stage of carcinogenesis and the microenvironment where tumor cells grow may influence the amount of EVs released by the cell. This neoplastic stage and microenvironment may also impact EVs’ components such as proteins and miRNA, determining their biological behavior. Most T-cell lymphomas have an aggressive clinical course and poor prognosis. Consequently, complementary alternative therapies are needed to improve the survival rates achieved with conventional treatments. In this work, we have characterized EVs isolated from ascites of mice bearing a very aggressive murine T-cell lymphoma and have studied their immunogenic properties. Small EVs were isolated by differential centrifugation, ultrafiltration, and ultracentrifugation at 100,000 × g on a sucrose cushion. The EVs were defined as exosomes by their morphology and size analyzed by electron microscopy, their floating density on a sucrose gradient, as well as their expression of endosome marker proteins ALIX, TSG-101; the tetraspanins CD63, CD9, and CD81. In addition, they contain tumor antigens, the marker for malignancy CD24, the heat shock protein HSP-70, and an unusual surface expression of HSP-90 was demonstrated. The administration of EVs isolated from ascites (EVs A) into naïve-syngeneic mice induced both humoral and cellular immune responses that allowed the rejection of subsequent tumor challenges.

    Tetra-O-acetate haloacetamido carbohydrate analogs (Tet-OAHCs) are novel alkylating agents that appear to have alkylating activity at the plasma membrane, specificity against neoplastic cells, and may potentiate host leukocyte influx. This study sought to characterize the chemical attributes and in vivo activity of Tet-OAHCs. Four Tet-OAHCs were assessed for their partition coefficient and alkylating activity to determine cellular environments where adduct formation would be favorable. In vitro, IC50 values of all four Tet-OAHCs were determined against Ehrlich ascites murine carcinoma, as well as two leukemias (U937 human monocytic leukemia and L1210 murine lymphoid leukemia) to assess their cytotoxicity in multiple neoplastic cell lines. In vivo, B6D2F1 and CD2F1 mice were challenged i.p. with Ehrlich ascites carcinoma prior to, or after being treated with a single dose of one of the analogs. Finally, a quantitative comparison of host leukocyte influx between Tet-OAHCs and other alkylating agents was performed to confirm previous in vivo observations that the tetra-O-acetate carbohydrate moiety is important for inducing a host leukocyte response in murine models. The results can be summarized as follows: 1) Tet-OAHCs appear to demonstrate high alkylating activity in amphiphilic environments. 2) All four congeners have comparable in vitro cytotoxicities against the neoplastic cell lines examined. 3) The analogs demonstrate marked in vivo activity in both B6D2F1 and CD2F1 mice challenged with a lethal dose of Ehrlich ascites carcinoma, and frequently produce long term survival at 60 days, which is not observed in simple halo derivatives or two currently approved antineoplastic agents (daunorubicin and mechlorethamine). These effects are observed when the agents are administered either before or after the tumor challenge. 4) The carbohydrate moiety appears to be important for potentiating host leukocyte influx, as Tet-OAHCs, but not other alkylating agents

    The labelling pattern of cellular phosphoinositides (PtdInsP(n)) was studied in Ehrlich ascites cells labelled in vivo for 24 h with myo-[2-(3)H]- or l-myo-[1-(3)H]inositol and exposed to anisotonic or isosmotic volume perturbations. In parallel experiments the cell volume ([(14)C]3-OMG space) was monitored. In hypotonic media the cells initially swelled osmotically and subsequently as expected showed a regulatory volume decrease (RVD) response. Concurrently, the cell content of PtdInsP(2) showed a marked, transient decrease and the content of PtdInsP a small, transient increase. The changes in PtdInsP(2) and PtdInsP content increased progressively with the extent of hypotonicity (in the range 1.00-0.50 relative osmolarity). No evidence was found for either hydrolysis of PtdInsP(2) or formation of PtdInsP(3). In hypertonic medium (relative osmolarity 1.50), cells initially shrank osmotically and subsequently as expected showed a small regulatory volume increase (RVI) response. Concurrently, the cell content of PtdInsP(2) showed a marked increase and the content of PtdInsP a small decrease, i.e. changes in the opposite direction of those seen in hypotonic media. In isosmotic media with high (100 mm) or low (0.8 mm) K(+) concentration, cells slowly swelled or shrank due to uptake or loss of isosmotic KCl. Under these conditions, with largely unchanged intracellular ionic strength, the cell content of PtdInsP(2) and PtdInsP remained constant. Our results show that PtdInsP(2) is not volume sensitive per se, and moreover that the regulatory volume adjustments in Ehrlich ascites cells are not mediated by PtdInsP(2) hydrolysis and its subsequent production of second messengers. The simplest interpretation of the observed effects would be that PtdInsP(2) is controlled by ionic strength, probably via activation/inhibition of phosphoinositide-specific phosphatases/kinases. In Ehrlich ascites cells, as shown previously, the opposing ion channels and transporters activated

    Objectives The aim of this article was to assess the success, safety, complication profile and factors associated with long-term patency of tunnelled peritoneal drains (PleurX) in the treatment of refractory malignant ascites. Methods Over a 4-year period, 28 consecutive patients (32 drain insertions) with refractory malignant ascites were treated with a PleurX drain. The study group comprised 7 males and 21 females (mean age, 61 years). A combination of fluoroscopic and ultrasound guidance was used to insert 4 drains; the remaining 28 drains were inserted under ultrasound guidance alone. Patient history, biochemical profiles, pathological and procedural records and clinical follow-up until death were reviewed. Statistical analysis included multivariate logistic regression analysis and Kaplan–Meier curves (p<0.05 was considered significant). Results There was a 100% technical success rate for the insertion of the drain; there were no procedure-related deaths and no major complications. Only minor complications were reported: three (10%) immediate; three (10%) early; and two (7%) late. Factors significantly associated with these complications included current chemotherapy, low haemoglobin levels, low albumin levels, high white cell count and high c-reactive protein levels. The length of time the drains remained in situ, and therefore patent, ranged from 5 to 365 days (mean, 113 days). Out of the original 28 tunnelled drains, 24 (86%) remained in situ and functioning until the patients’ death. Four (14%) drains dislodged and a subsequent PleurX drain was inserted on the opposite side of the abdominal wall. These new drains remained patent until the patient’s death. The annual event rate was 0.45 events per year. A comorbid diagnosis of renal disease or chemotherapy was significantly related to a decreased length of patency. Conclusion The use of tunnelled peritoneal drains is safe and effective and we would advocate their use as a first-line approach in

    In vitro anticancer drug sensitivity tests have been performed for various types of cancers, and a relationship with clinical response has been observed. The collagen gel droplet-embedded culture drug sensitivity test (CD-DST) is a new in vitro anticancer drug sensitivity test by Yabushita et al., recently reported to be useful in ovarian cancer. CD-DST allows analysis of a small number of cells, compared to other anticancer drug sensitivity tests. Here, we report a successful analysis of anticancer drug sensitivity by CD-DST using cancerous ascites and pleural fluid samples from 2 patients with advanced ovarian cancer. To our knowledge, this is only the second report of the application of CD-DST in ovarian cancer, and our results suggest that CD-DST could be helpful in the selection of anticancer drugs for neoadjuvant chemotherapy in advanced ovarian cancer.

    A partially purified preparation of DNA polymerase alpha, obtained from the cytosol of Ehrlich ascites tumour cells, has been found to catalyze the conversion of MVM parvovirus, SS DNA (5 kilobases) to RF in vitro. The reaction initiates at a natural 55 base pair hairpin which exists at the 3' terminus of MVM SS DNA. The SS leads to RF conversion is sensitive to aphidicolin, resistant to ddTTP and is promoted by purine ribonucleoside 5' triphosphates, a phenomenon which could not be explained simply by stabilization effects on the in vitro deoxynucleotide precursor pool. In the absence of rNTPs, nascent complementary strands frequently terminate prematurely at a preferred location, between 1300 and 1700 nucleotides from the initiating 3' hairpin terminus. This in vitro system, involving self-primed parvovirus DNA synthesis, provides a convenient assay for those components of the mammalian replicative DNA polymerase complex which are required for the elongation of nascent DNA chains.

    ABSTRACT A critical feature of a potential antimicrobial target is the characteristic of being essential for growth and survival during host infection. For bacteria, genome-wide essentiality screens are usually performed on rich laboratory media. This study addressed whether genes detected in that manner were optimal for the identification of antimicrobial targets since the in vivo milieu is fundamentally different. Mutant derivatives of a clinical isolate of Acinetobacter baumannii were screened for growth on human ascites, an ex vivo medium that reflects the infection environment. A subset of 34 mutants with unique gene disruptions that demonstrated little to no growth on ascites underwent evaluation in a rat subcutaneous abscess model, establishing 18 (53%) of these genes as in vivo essential. The putative gene products all had annotated biological functions, represented unrecognized or underexploited antimicrobial targets, and could be grouped into five functional categories: metabolic, two-component signaling systems, DNA/RNA synthesis and regulation, protein transport, and structural. These A. baumannii in vivo essential genes overlapped poorly with the sets of essential genes from other Gram-negative bacteria catalogued in the Database of Essential Genes (DEG), including those of Acinetobacter baylyi, a closely related species. However, this finding was not due to the absence of orthologs. None of the 18 in vivo essential genes identified in this study, or their putative gene products, were targets of FDA-approved drugs or drugs in the developmental pipeline, indicating that a significant portion of the available target space within pathogenic Gram-negative bacteria is currently neglected.

    A competition radioimmunoassay was developed, utilizing a murine monoclonal antibody to human pancreatic adenocarcinoma cells. Immunoblotting of a standard antigen preparation from either serum or ascites fluid after electrophoresis in 1% agarose showed that the specific DUPAN-2 activity resided in two major high molecular weight bands. DU-PAN-2 antigen levels were expressed as arbitrary units based on a standard partially purified antigen preparation. The inhibition curve with standard antigen was reproducible (SD < 10%) and essentially linear from 25 to 200 units/ml. The mean DU-PAN-2 antigen concentration for the sera from 126 normal individuals was 81 units/ml. Sera from pediatric patients with malignancy had a mean of 127 units/ml, while nasopharyngeal, stage III melanoma, and ovarian carcinoma patients had means of 89, 92, and 119 units/ml, respectively. All values in normal subjects as well as the melanoma, nasopharyngeal, ovarian, and pediatric cancer patients were less than 400 units/ml. Intermediate antigen levels were detected in patients with alimentary tract malignancies. Eight of 20 gastric cancer and 8 of 76 colorectal carcinoma patients and 3 patients with benign or nonmalig nant gastrointestinal tract disease had DU-PAN-2 values exceeding 400 units/ml. Ascites fluids from 6/6 and pancreatic juice from 2/2 pancreatic cancer patients had values greater than 750 units/ml. Serum from 68% of the 89 pancreatic cancer patients tested had DU-PAN-2 antigen levels greater than 400 units/ml. The mean serum value in this patient population was 4888 units/ml.

    Twenty patients with cirrhosis and ascites but no renal failure were given piretanide, a new loop diuretic, in order to investigate its efficacy and to relate the diuretic response with the pretreatment plasma aldosterone concentration. Eleven patients responded to piretanide 12 mg/day (equivalent in potency to 80 mg furosemide); there was no response in nine patients. Both groups were similar with regard to liver function, plasma urea, serum creatinine, plasma electrolytes, urine volume, and urine potassium concentration. The basal urinary sodium excretion was significantly higher in those patients who responded (23.6 +/- 5.7 mmol/day vs. 4.3 +/- 1.42 mmol/day; P < 0.01) (M +/- SE). Plasma renin activity (PRA) and plasma aldosterone concentration (PAC) were normal or only slightly increased in patients who responded to piretanide (PRA = 1.22 +/- 0.20 ng/ml/h; PAC = 12.25 +/- 2.20 ng/100 ml) and very high in patients who did not respond (PRA = 8.71 +/- 1.18 ng/ml/h; PAC = 84.6 +/- 16.2 ng/100 ml) (P < 0.001). Patients unresponsive to piretanide 12 mg/day also failed to respond when the dose was increased to 24 mg/day. However, the addition of spironolactone, 150 mg/day, to piretanide was followed in these patients by a marked increase in diuresis and natriuresis. These results strongly suggest that the pre-treatment level of aldosterone is an important factor influencing the response to loop diuretics in patients with non-azotaemic cirrhosis and ascites.

    Local renin-angiotensin systems exist in various malignant tumor tissues; this suggests that the main effector peptide, angiotensin II, could act as a key factor in tumor growth. The underlying mechanisms for the anti-angiogenic effect of angiotensin II type 1 receptor blockers need to be further evaluated. The present study was carried out to investigate the anti-angiogenic effect of olmesartan alone or in combination with sorafenib, an angiotensin (1–7) agonist or an angiotensin (1–7) antagonist in Ehrlich's ascites carcinoma-bearing mice. The tumor was induced by intradermal injection of Ehrlich's ascites carcinoma cells into mice. Tumor discs were used to evaluate the microvessel density; the serum levels of vascular endothelial growth factor (VEGF) and serum insulin-like growth factor I (IGF-I); and their intratumoral receptors, VEGF receptor-2 and IGF-I receptor, respectively. All parameters were determined following the treatment course, which lasted for 21 days post-inoculation. Monotherapy with olmesartan and its combination with sorafenib resulted in a significant reduction in microvessel density and serum levels of VEGF and IGF-I, as well as their intratumoral receptors. In addition, the combination of olmesartan (30 mg/kg) with an angiotensin (1–7) agonist reduced the microvessel density, IGF-I serum levels and the levels of its intratumoral receptor. In conclusion, olmesartan reduced the levels of the angiogenesis markers IGF-I and VEGF and down-regulated the intratumoral expression of their receptors in a dose-dependent manner, and these effects were dependent on the angiotensin (1–7) receptor. These results suggest that olmesartan is a promising adjuvant to sorafenib in the treatment of cancer. PMID:24465768

    Naturally occurring pterostilbene (PTER) and isothiocyanate (ITC) attract great attention due to their wide range of biological properties, including anti-cancer, anti-leukemic, anti-bacterial and anti-inflammatory activities. A novel class of hybrid compound synthesized by introducing an ITC moiety on PTER backbone was evaluated for its anti-cancer efficacy in hormone-dependent breast cancer cell line (MCF-7) in vitro and Ehrlich ascitic tumor bearing mice model in vivo. The novel hybrid molecule showed significant in vitro anti-cancer activity (IC{sub 50}=25±0.38) when compared to reference compound PTER (IC{sub 50}=65±0.42). The conjugate molecule induced both S and G2/M phase cell cycle arrest as indicated by flow cytometry analysis. In addition, the conjugate induced cell death was characterized by changes in cell morphology, DNA fragmentation, activation of caspase-9, release of cytochrome-c into cytosol and increased Bax: Bcl-2 ratio. The conjugate also suppressed the phosphorylation of Akt and ERK. The conjugate induced cell death was significantly increased in presence of A6730 (a potent Akt1/2 kinase inhibitor) and PD98059 (a specific ERK inhibitor). Moreover, the conjugated PTER inhibited tumor growth in Ehrlich ascitic cell induced tumor bearing mice as observed by reduction in tumor volume compared to untreated animals. Collectively, the pro-apoptotic effect of conjugate is mediated through the activation of caspases, and is correlated with the blockade of the Akt and ERK signaling pathways in MCF-7 cells. - Highlights: • Conjugate was prepared by appending isothiocyanate moiety on pterostilbene backbone. • Conjugate showed anticancer effects at comparatively lower dose than pterostilbene. • Conjugate caused blockage of the Akt and ERK signaling pathways in MCF-7 cells. • Conjugate significantly reduced solid tumor volume as compared to pterostilbene.

    Enzyme fractions were isolated from Ehrlich ascites cells which introduced methyl groups into methyl deficient rat liver mRNA and unmethylated vaccinia mRNA. The methyl groups were incorporated at the 5' end into cap 1 structures by the viral enzyme, whereas both cap 0 and cap 1 structures were formed by the Ehrlich ascites cell enzymes. Preliminary results indicate the presence of adenine N/sup 6/-methyltransferase activity in Ehrlich ascites cells. These results indicate that mRNA deficient in 5'-cap methylation and in internal methylation of adenine accumulated in rats on exposure to ethionine. The methyl-deficient mRNA isolated from the liver of ethionine-fed rats differed in its translational properties from mRNA isolated from control animals. Preliminary experiments indicate that single topical application of 17n moles of TPA to mouse skin altered tRNA methyltransferases. The extent of methylation was increased over 2-fold in mouse skin treated with TPA for 48 hours. These changes have been observed as early as 12 hours following TPA treatment. In contrast, the application of initiating dose of DMBA had no effect on these enzymes. It should be emphasized that the changes in tRNA methyltransferases produced by TPA are not merely an increase of the concentration of the enzyme, rather that they represent alterations of specificity of a battery of enzymes. In turn the change in enzyme specificity can produce alterations in the structure of tRNA. (ERB)

    Intravenous injection of microparticles (MPs) is a tool to reveal susceptibility to pulmonary hypertension (PH) syndrome (PHS, ascites) in broilers. After injection MPs get lodged in pulmonary arterioles and cause localized inflammation. To examine the expression of chemokines/cytokines during the MP-induced pulmonary inflammatory response, lungs were collected from 4-week-old broilers (6/line/time point) from the PHS-resistant (RES) and -susceptible (SUS) broilers before (0h) and after (2, 6, 12, 24, and 48h) MP injection and analyzed using quantitative RT-PCR. In both lines, expression of interleukin-1beta (IL-1beta), IL-6, IL-8, and K60 increased from 0 to 6h, reached peak levels at 6 and 12h, and decreased thereafter, whereas IL-4 and interferon gamma (IFN-gamma) expression remained elevated past 12h. Lungs from the RES line broilers had higher expression (P<0.05) of IL-1beta and IL-6 at 2, 6, and 12h; higher IL-8 at 6 and 12h; higher K60 at 6, 12, and 24h; higher IL-4 at 12, 24, and 48h and higher IFN-gamma expression at 6 and 48h post-MP injection than SUS line broilers. Higher expression of chemokines/cytokines in RES compared to SUS line lungs may explain the ability of RES line broilers to effectively counteract the MP-induced PH and resolve the vascular occlusion.

    Background This study aimed to propose treatment strategies for high-output chylous ascites (CA) developed after gastric cancer surgery. Methods The data of patients with CA after gastric cancer surgery in three high volume Training and Research Hospitals between 2005 and 2015 were retrospectively evaluated. Results Nine patients out of 436 gastrectomies were detected with CA. The mean amount of daily fistula output was 939 mL. Treatment consisted of cessation of oral feeding, total parenteral nutrition (TPN), somatostatin analogs administration, clamping and/or removal of the drainage tube, diuretic administration and diet therapy with medium-chain triglycerides (MCTs) alone or in combination. The mean fistula closure time and length of hospital stay were 23 and 24 days respectively. Hemopneumothorax developed during right subclavian vein catheterisation for TPN implementation in one patient. There was no mortality. Conclusions Combined cessation of oral feeding and TPN are usually used for treatment of CA as first-line treatment. However, TPN is no harmless. Although our data are limited they do allow us to conclude that diet with MCT’s may use for medical treatment of CA as first-line. PMID:27284475

    Apart from commonly employed target-specific labeling/adsorption of antibodies over Au-NPs surface for the creation of localized aggregates, an alternative approach using optical tweezers (OT) driven by hybrid-TEM*11 mode has been devised and exploited for in vitro detection of Ehrlich ascites carcinoma cells (EAC) relying on enhanced scattering. Intra-cavity generated spatially featured asymmetric (SFA) laser beam (λ = 532 nm) has effected simultaneous trapping of mice-EAC cells and in-situ crowd/assembly of incubated Au-NPs/small gold nano-aggregates (created from two or more individual Au-NPs). Relatively larger focus spot created by tightly focused SFA beam than frequently employed Gaussian-mode in OT has offered an extended working area and hence dilute heating has taken care of EAC cells. GNA improves significantly the sensitivity of diagnostics relying on scattered light and the safety and efficacy of therapeutic nanotechnologies for the diseases of cancer and vascular system in medicine.

    This study was performed to elaborate the best conditions for measuring the redox activity of Ehrlich ascites tumour cells by using a new tetrazolium salt, cyantolyl tetrazolium chloride (CTC). This tetrazolium salt forms a fluorescent water-insoluble formazan on reduction on the surface of intact vital cells. The influences of fixation and of various substrates and electron carriers on the cellular reduction of CTC were investigated quantitatively using an elution technique. The amount of formazan obtained after incubating vital cells with Meldola Blue as electron carrier was greater than that obtained with Methylene Blue, menadione, 2,6-dichloroindophenol, 1-methoxyphenazine methosulphate or phenazine methosulphate. Using flow cytometry, the formazan production per cell and, after staining the nuclear DNA, the distribution of the redox activity in the cell population can be visualized with satisfactory resolution. We conclude from our findings that dehydrogenases are only partially involved in the reduction of tetrazolium salts by intact cells and that a redox activity, probably related to a cell membrane-bound NAD(P)H-oxidase system, is mainly measured.

    Alpha 1, alpha 2- and beta-Adrenoceptor densities and catecholamine responsiveness in established hepatoma cells, rat ascites hepatoma AH13, AH66, AH66F, AH109A, AH130 and AH7974 cells and human hepatocellular carcinoma HLF and HepG2 cells, were compared with those in normal rat hepatocytes and Chang liver cells. Alpha 1-Adrenoceptor densities measured by [3H]prazosin bindings were not detected in all hepatoma cell lines. Alpha 2-Adrenoceptor densities measured by [3H]clonidine bindings were also barely detected in hepatoma cell lines except for AH130 cells and HepG2 cells. Regarding beta-adrenoceptor, AH109A, AH130 and AH7974 cells had much more [125I]iodocyanopindolol binding sites than normal rat hepatocytes, although we could not detect the binding in HepG2 cells. Adenylate cyclase of normal rat hepatocyte and Chang liver cells were stimulated by beta 2-adrenergic agonist salbutamol, while the cyclase in hepatoma cells had no beta 2-adrenergic response but a beta 1-type response. These findings indicate that the characteristics of adrenergic response in hepatoma cell lines is very different from that in normal hepatocytes, suggesting a participation in the hepatocarcinogenesis and/or the autonomous proliferation of hepatoma cells.

    LMPAB is a linear beta-(1-3)-glucan we isolated from polysaccharide extract of Agaricus blazei Murill (AbM). Effects of LMPAB on splenic natural killer (NK) cell activity, splenocyte proliferation, index of spleen and thymus, IFN-gamma expression in spleen and the concentration of IL-12, IL-18 and TNF-alpha in serum of S180 ascitic tumor-bearing mice were detected. The results showed that intraperitoneal injection of LMPAB (100 mg x kg(-1) x d(-1)) significantly increased the thymus index. LMPAB augmented splenic NK cell activity in a dose-dependent manner (50-200 mg x kg(-1) x d(-1)). The concanavalin A (3 microg/ ml) stimulated splenocyte proliferation was significantly enhanced by LMPAB at dosages of 50, 100 or 200 mg x kg(-1) x d(-1). Further studies showed that LMPAB (50, 100 or 200 mg x kg(-1) x d(-1), 14d) significantly increased the production of IL-12, TNF-alpha, IL-18 and the expression IFN-gamma as determined by ELISA and immunohistochemistry, respectively. These results clearly indicate that the anti-tumor effects of LMPAB are closely associated with up-regulation of activity of NK cells, expression of IFN-gamma in spleen and the systemic level of IL-12, IL-18 and TNF-alpha in tumor-bearing mice.

    Turnover of (/sup 14/C)thiamin was studied in mice with Ehrlich ascites carcinoma fed a thiamin-deficient diet and injected with 5 or 2 micrograms/mouse of the labeled vitamin. The process of conversion of (/sup 14/C)thiamin to thiamin pyrophosphate (TPP) was monitored by measuring the activities of transketolase, pyruvate dehydrogenase, and oxoglutarate dehydrogenase. The amount of coenzyme-unsaturated apotransketolase was assessed by measuring the TPP effect--determining transketolase activity with and without the addition of TPP in vitro. Tumor growth was accompanied by thiamin deficiency, manifested in an increase in (/sup 14/C)thiamin incorporation into the host tissues and the absence of saturation of the tissues with the labeled vitamin over 13 days. Increased values for the turnover coefficients, reduction of thiamin-dependent enzyme activities, elevation of the TPP effect, and a decrease in urinary excretion of the radioactive products also provided evidence for a disturbance in thiamin metabolism. The severity of the disturbance in thiamin metabolism during malignant tumor growth was directly related to the dose of the exogenous vitamin.

    De novo hepatitis B is associated with a high risk of hepatic failure often resulting in fatal fulminant hepatitis even when nucleotide analogues are administered. A 77-year-old female developed de novo hepatitis B after R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) treatment for diffuse large B-cell lymphoma. Hepatitis B virus (HBV) isolated from the patient was of genotype Bj, with a precore mutation (G1896A) exhibiting an extremely high viral load at the onset of hepatitis. She showed markedly high levels of transaminase with mild jaundice on admission and rapid decrease of prothrombin activity after admission. Although acute liver failure was averted by the administration of entecavir and corticosteroid pulse therapy, liver volume decreased to 860 ml, and marked hypoalbuminemia accompanying massive ascites occurred 2 months after the onset of hepatitis and persisted for 3 months with high levels of HBV DNA and mild abnormal alanine aminotransferase levels. Frequent infusions of albumin solution, nutrition support, and alleviation therapy showed limited effect. However, overall improvement along with HBV DNA reduction was observed after increasing the dose of entecavir and completion of prednisolone that was administered with a minimum dose for adrenal insufficiency. An immediate and sufficient suppression of virus replication with potent antiviral therapy is critical, particularly in patients infected with HBV precore mutation (G1896A) and/or Bj genotype, which may have a high viral replication and direct hepatocellular damage.

    Purification of immunoglobulin M (IgM) antibodies could be challenging, and is often characterized by the optimization of the purification protocol to best suit the particular features of the molecule. Here, two different schemes were compared to purify, from ascites, the 1E4 IgM monoclonal antibody (mAb) previously raised against the stage of redia of the trematode Fasciola hepatica. This immunoglobulin is used as capture antibody in an immunoenzymatic assay to detect parasite ongoing infection in its intermediate hosts. The first purification protocol of the 1E4 mAb involved two chromatographic steps: an affinity chromatography on a Concanavalin A matrix followed by size exclusion chromatography. An immunoaffinity chromatography was selected as the second protocol for one-step purification of the antibody using the crude extract of adult parasites coupled to a commercial matrix. Immunoreactivity of the fractions during purification schemes was assessed by indirect immunoenzymatic assays against the crude extract of F. hepatica rediae, while purity was estimated by protein electrophoresis. Losses on the recovery of the antibody isolated by the first purification protocol occurred due to protein precipitation during the concentration of the sample and to low resolution of the size exclusion molecular chromatography step regarding this particular immunoglobulin. The immunoaffinity chromatography using F. hepatica antigens as ligands proved to be the most suitable protocol yielding a pure and immunoreactive antibody. The purification protocols used are discussed regarding efficiency and difficulties.

    Anticancer activities of p-menth-1-ene-4,7-diol (EC-1) isolated from Eucalyptus camaldulensis Dhnh. were studied on Ehrlich ascites carcinoma (EAC) cells by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. Anticancer activities also analyzed in EAC-bearing mice by assessment of cancer growth inhibition, changes in cancer volume, changes in life span, and hematological parameters. Apoptosis was analyzed by fluorescence microscope, DNA fragmentation assay, and flow cytometry. The expression of apoptosis-related genes, Bcl-2, Bcl-X, PARP-1, p53, and Bax, were analyzed using polymerase chain reaction (PCR). EC-1 significantly inhibited proliferation of EAC cells in vivo and restored the altered hematological parameters of EAC-bearing mice. Cytological observation by fluorescence microscope showed apoptosis of EAC cells upon treatment with EC-1. Also, DNA fragmentation assay revealed EAC cells' apoptosis following EC-1 treatment. Increased mRNA expressions of p53 and Bax genes and negative expressions of Bcl-2 and Bcl-X were observed in cells treated with EC-1. These findings confirmed the induction of apoptosis by EC-1. In addition, MTT assay showed dose-dependent anticancer activity of EC-1 against EAC cell. Cell cycle analysis revealed that EC-1 treatment caused suppression of EAC cells at S phase. To conclude, EC-1 is a novel anticancer compound and showed antiproliferative and apoptotic activities in cellular and mice models.

    Context: Anisochilus carnosus (L.f.) wall belonging to the family Lamiaceae is a plant that is widely used in folk medicine for treating eczema, cold, cough, and fever. Objective: In the present study, we explored the anticancer potential of A. carnosus leaves against Ehrlich ascites carcinoma (EAC) and estimated the quantity of luteolin present in various extracts and fractions of A. carnosus by high-performance thin layer chromatography (HPTLC) fingerprinting. Materials and Methods: Various factors such as tumor volume, tumor cell viability, tumor weight, prolongation of lifespan, and hematological parameters were assessed. Result: We observed a significant lowering in tumor volume, tumor weight, and cell viability in EAC-induced mice following intervention with A. carnosus extracts. Also, there was a considerable prolongation of host lifespan and restoration of hematological parameters to almost normal levels with A. carnosus treatment. HPTLC fingerprinting of various extracts and fractions of A. carnosus along with luteolin as the reference standard revealed the occurrence of luteolin in all tested extracts and fractions of A. carnosus with the highest concentration being reported in the ethanol fraction. Conclusion: A. carnosus exhibits potent anti-tumor potential which can most likely be attributed to the occurrence of different phytochemicals such as phytosterols, terpenoids, and flavonoids in the plant. Further studies to isolate compounds from A. carnosus and understand the mechanism of anti-tumor activity would be worthwhile. SUMMARY EAC induced mice that received A. carnosus treatment exhibited significant reduction in tumor volume, tumor weight and tumor cell viability. Their life span was considerably prolonged. We detected luteolin in A. carnosus aqueous and ethanol extract using HPTLC. Hence, anticancer activity of A. carnosus can be partly attributed to the presence of luteolin. PMID:26929584

    The clinical success of the applicability of tea polyphenols awaits efficient systemic delivery and bioavailability. Herein, following the concept of nanochemoprevention, which uses nanotechnology for enhancing the efficacy of chemotherapeutic drugs, we employed tea polyphenols, namely theaflavin (TF) and epigallocatechin-3-gallate (EGCG) encapsulated in a biodegradable nanoparticulate formulation based on poly(lactide-co-glycolide) (PLGA) with approximately 26% and 18% encapsulation efficiency, respectively. It was observed that TF/EGCG encapsulated PLGA nanoparticles (NPs) offered an up to ~7-fold dose advantage when compared with bulk TF/EGCG in terms of exerting its antiproliferative effects and also enhanced the anticancer potential of cisplatin (CDDP) in A549 (lung carcinoma), HeLa (cervical carcinoma), and THP-1 (acute monocytic leukemia) cells. Cell cycle analysis revealed that TF/EGCG-NPs were more efficient than bulk TF/EGCG in sensitizing A549 cells to CDDP-induced apoptosis, with a dose advantage of up to 20-fold. Further, TF/EGCG-NPs, alone or in combination with CDDP, were more effective in inhibiting NF-κB activation and in suppressing the expression of cyclin D1, matrix metalloproteinase-9, and vascular endothelial growth factor, involved in cell proliferation, metastasis, and angiogenesis, respectively. EGCG and TF-NPs were also found to be more effective than bulk TF/EGCG in inducing the cleavage of caspase-3 and caspase-9 and Bax/Bcl2 ratio in favor of apoptosis. Further, in vivo evaluation of these NPs in combination with CDDP showed an increase in life span (P<0.05) in mice bearing Ehrlich’s ascites carcinoma cells, with apparent regression of tumor volume in comparison with mice treated with bulk doses with CDDP. These results indicate that EGCG and TF-NPs have superior cancer chemosensitization activity when compared with bulk TF/EGCG. PMID:26586942

    Background Dietary energy restriction (DER) has been well established as a potent anticancer strategy. Non-adoption of restricted diet for an extended period has limited its practical implementation in humans with a compelling need to develop agents that mimic effects similar to DER, without reduction in actual dietary intake. Glycolytic inhibitor, 2-deoxy-D-glucose (2-DG), has recently been shown to possess potential as an energy restriction mimetic agent (ERMA). In the present study we evaluated the effect of dietary 2-DG administration on a mouse tumor model, with a focus on several potential mechanisms that may account for the inhibition of tumorigenesis. Methodology/Principal Findings Swiss albino strain ‘A’ mice were administered with 0.2% and 0.4% w/v 2-DG in drinking water for 3 months prior to tumor implantation (Ehrlich’s ascites carcinoma; EAC) and continued till the termination of the study with no adverse effects on general physiology and animal growth. Dietary 2-DG significantly reduced the tumor incidence, delayed the onset, and compromised the tumor growth along with enhanced survival. We observed reduced blood glucose and serum insulin levels along with decreased proliferating cell nuclear antigen (PCNA) and bromodeoxyuridine positive (BrdU+) tumor cells in 2-DG fed mice. Also, reduced levels of certain key players of metabolic pathways such as phosphatidylinositol 3-kinase (PI3K), phosphorylated-Akt and hypoxia inducible factor-1 alpha (HIF-1α) were also noted in tumors of 2-DG fed mice. Further, decrease in CD4+/CD8+ ratio and T-regulatory cells observed in 2-DG fed mice suggested enhanced antitumor immunity and T cell effector function. Conclusion/Significance These results strongly suggest that dietary 2-DG administration in mice, at doses easily achievable in humans, suitably modulates several pleotrophic factors mimicking DER and inhibits tumorigenesis, emphasizing the use of ERMAs as a promising cancer preventive strategy.

    TA3 ascites tumor cells maintained in vitro as a dilute suspension in 0.9% NaCl solution (physiological saline) were found to undergo time-dependent degenerative processes leading to alterations in both membrane characteristics and tumor transplantation properties. A 30% decrease in the negative cellular surface charge density occurred within 2 hr. when TA3 cells were incubated in a 0.9% NaCl solution at 23 °C. A similar reduction in negative surface charge density occurred within 0.5 hr. when the medium was maintained at 37 °C. This time-dependent reduction in surface charge was prevented when cellular metabolism was blocked either by maintaining the medium at 4 °C. or by adding 1 mM cyanide ion to a 23 °C medium. TA3 cells incubated as a dilute suspension in 0.9% NaCl solution at 23 °C also exhibited a large 9 time-dependent reduction in proliferative capacity in isogeneic LAF1/J hosts, as indicated by an increase in the tumor dose for 50% mortality (TD50). Lowering the temperature of the medium to 4 °C was observed to slow the onset of the degenerative processes that lead to a decreased transplantability of TA3 cells. The modification in growth properties of TA3 cells maintained in vitro was found to be attributable in part to an alteration in tumor histocompatibility. This effect was demonstrated by comparing the tumor growth kinetics and TD50 values in normal hosts versus hosts that had been immunosuppressed by whole-body irradiation. Following the in vitro maintenance of TA3 cells, nigrosin dye exclusion tests were performed as a means of assessing cell viability. Evidence obtained in this series of experiments indicated that vital staining is an inadequate criterion for judging either the extent of cell membrane damage or the loss of cellular proliferative capacity.

    Doxorubicin (DOX) is a well-known anticancer drug used for the treatment of a wide variety of cancers. However, undesired toxicity of DOX limits its uses. To address the issue of minimizing toxicity of DOX by making it targeted towards cancer cells, DOX was entrapped in self-assembled 6-O-(3-hexadecyloxy-2-hydroxypropyl)-hyaluronic acid (HDHA) nanoparticles. We hypothesized that by encapsulating the drug in biodegradable nanoparticles, its therapeutic efficacy would improve, if targeted against cancer cells. We synthesized cell receptor targeted, DOX loaded HDHA nanoparticles (NPs) and non-targeted DOX loaded O-hexadecylated dextran (HDD) nanoparticles (NPs) and characterized them for their entrapment efficiency, percent yield, drug load, surface morphology, particle size and in vitro drug release. The anticancer efficacy of DOX loaded HDHA-NPs was evaluated by measuring the changes in tumor volumes, tumor weights, and mean survival rate of Swiss albino mice grafted with Ehrlich's ascites carcinoma (EAC) cells. For this, the animals were given HDHA-DOX-NPs (1.5 mg/kg b.wt.) intravenously and a green tea polyphenol, Epigallocatechin-3-gallate (EGCG) (20 mg/kg b.wt.), orally through gavage. The targeted NP dose with EGCG significantly increased mean survival time of the animals and enhanced the therapeutic efficacy of the drug compared to the non-targeted NPs and free DOX. Further, we showed that these NPs (HDD and HDHA) were more active in the presence of EGCG than DOX alone in inducing apoptosis in EAC cells as evident by an increase in sub-G1 cells (percent), Annexin V positive cells and chromatin condensation along with the reduction in mitochondrial membrane potential (MMP). The study demonstrates that DOX loaded HDHA-NPs along with EGCG significantly inhibit the growth of EAC cells with ∼38-fold dose advantage compared to DOX alone and thus opens a new dimension in cancer chemotherapy.

    The biochemical effects of the 2-nitroimidazole hypoxic cell radiosensitizers KIN-804, KIN-806, and their analogues KIN-844 and TX-1877 on brain acetylcholinesterase (AChE) and hepatic free radical scavenging systems, such as reduced glutathione (GSH) and glucose-6-phosphate dehydrogenase (G-6-PDH) levels, and hepatic antioxidants, such as superoxide dismutase (SOD) and catalase, were evaluated in Ehrlich ascites carcinoma (EAC)-bearing Swiss albino mice. The assay of brain AChE revealed nonsignificant changes with all drugs examined. To evaluate the hepatic metabolic capacity, groups of mice were divided into control, EAC-inoculated, 10-Gy local gamma-irradiated, and KIN-804, KIN-844, KIN-806, or TX-1877 (50 mg/kg body weight, i.p.) groups, and gamma-irradiation was combined with each drug. EAC inoculation markedly suppressed GSH, G-6-PDH, SOD, and catalase levels. On the other hand, treatment with gamma-irradiation significantly enhanced them. The treatment of EAC-bearing mice with each drug alone in the absence of gamma-irradiation revealed that KIN-806 and its derivative TX-1877 showed antitumor activity through their significant recovery of GSH and SOD levels, respectively, in the EAC-bearing mice group. Similarly, the combined treatment of EAC-bearing mice with gamma-irradiation with each of the drugs tested showed that KIN-806 and TX-1877 significantly increased GSH and SOD, and to a lesser extent G-6-PDH and catalase levels. On the other hand, KIN-804 and KIN-844 had only a nonsignificant effect on all parameters examined. In conclusion, these data reveal that the administration of KIN-806 and TX-1877 with or without subsequent gamma-irradiation, resulted in significant recovery of GSH and SOD activities that were inhibited by EAC inoculation.

    The present study is an attempt to investigate the possibility that ultraviolet irradiation in the presence of pheomelanin may be more harmful to cells than the irradiation in the presence of eumelanin. The effects of UV-visible irradiation upon Ehrlich ascites carcinoma cells in the presence of the melanin isolated from human black hair (eumelanin) or from red hair (pheomelanin) were investigated. Irradiation of these cells was found to produce cell lysis, as observed by leakage of 51Cr from labeled cells and intracellular lactic dehydrogenase from the cells and decrease in cell viability demonstrated by the trypan blue exclusion test. The three parameters were quantitatively parallel to one another under various experimental conditions, namely different periods of irradiation and irradiation in the presence of different concentrations of melanin. The above effects were more pronounced when the irradiation was carried out in the presence of melanin from red hair than in the presence of black-hair melanin. In the absence of either melanin, the irradiation did not produce any significant effect in cell viability or cell lysis. Irradiation of the cells in the presence of red-hair melanin also decreased the transplantability of these cells. These observations clearly show that irradiation of cells in the presence of pheomelanin could produce cytotoxic effects. The present experimental design may have application in the development of in vitro models for the study of UV radiation-induced cutaneous carcinogenesis. The reactions of pheomelanin may be related to the susceptibility of ''Celtic'' skin to UV radiation-induced skin damage and carcinogenesis.

    Gastrodia elata Blume (G. elata) is a famous restorative food in East Asia. It can be used as an auxiliary reagent in hepatocellular carcinoma (HCC) treatment. Previous studies unveiled that G. elata exhibited immunomodulatory activities. To explore the active ingredients contributing to its immunomodulatory activities, gastrodin, vanillin, and parishin B were purified from G. elata and their anti-HCC effects were assessed in vivo. Among these compounds, only gastrodin was capable of repressing transplanted H22 ascitic hepatic tumor cell growth in vivo with low toxicity. Further investigations were designed to explore the effects of gastrodin on the immune system of tumor-bearing mice and potential molecular mechanisms underlying these effects. Our data showed that gastrodin ameliorated tumor cell transplantation-induced activation of endogenous pro-apoptotic pathway in CD4 + T cells and abnormalities in serum cytokine profiles in host animals. These events enhanced cytotoxic activities of natural killer and CD8 + T cells against H22 hepatic cancer cells. Gastrodin administration specifically upregulated mRNA levels of several nuclear factor κB (NF-κB) responsive genes in CD4 + T cells but not in CD8 + T cells. Chromatin immunoprecipitation assay showed that gastrodin increased the association of NF-κB p65 subunit to the promoter regions of IL-2 and Bcl-2 encoding genes in CD4 + T cells. Our investigations demonstrated that gastrodin is the main active ingredient contributing to the anticancer immunomodulatory properties of G. elata. Promoting NF-κB-mediated gene transcription in CD4 + T cells is implicated in its immunomodulatory activity. - Highlights: • Gastrodin stimulates anticancer immune response. • Gastrodin represses tumor transplantation-induced CD4 + T cell apoptosis. • Gastrodin activates NF-κB activity in CD4 + T cells.

    The mechanisms controlling the volume-regulated anion current (VRAC) are incompletely elucidated. Here, we investigate the modulation of VRAC by cellular cholesterol and the potential involvement of F-actin, Rho, Rho kinase, and phosphatidylinositol-(4,5)-bisphosphate [PtdIns(4,5)P(2)] in this process. In Ehrlich-Lettre ascites (ELA) cells, a current with biophysical and pharmacological properties characteristic of VRAC was activated by hypotonic swelling. A 44% increase in cellular cholesterol content had no detectable effects on F-actin organization or VRAC activity. A 47% reduction in cellular cholesterol content increased cortical and stress fiber-associated F-actin content in swollen cells. Cholesterol depletion increased VRAC activation rate and maximal current after a modest (15%), but not after a severe (36%) reduction in extracellular osmolarity. The cholesterol depletion-induced increase in maximal VRAC current was prevented by F-actin disruption using latrunculin B (LB), while the current activation rate was unaffected by LB, but dependent on Rho kinase. Rho activity was decreased by approximately 20% in modestly, and approximately 50% in severely swollen cells. In modestly swollen cells, this reduction was prevented by cholesterol depletion, which also increased isotonic Rho activity. Thrombin, which stimulates Rho and causes actin polymerization, potentiated VRAC in modestly swollen cells. VRAC activity was unaffected by inclusion of a water-soluble PtdIns(4,5)P(2) analogue or a PtdIns(4,5)P(2)-blocking antibody in the pipette, or neomycin treatment to sequester PtdIns(4,5)P(2). It is suggested that in ELA cells, F-actin and Rho-Rho kinase modulate VRAC magnitude and activation rate, respectively, and that cholesterol depletion potentiates VRAC at least in part by preventing the hypotonicity-induced decrease in Rho activity and eliciting actin polymerization.

  1. The effect of atebrine and an acridine analog (BCMA) on the coenzyme fluorescence spectra of cultured melanoma and Ehrlich ascites (EL2) cells.

    Coenzyme fluorescence spectra of single living cells are due to free pyridine nucleotides (folded configuration), bound pyridine nucleotides (unfolded configuration) and a third component, possibly a mixture or flavins. Such spectra can be used to recognize possible differences in coenzyme composition between cell lines or changes of metabolic pathways due to chemicals acting at levels below or above cytotoxicity, by high resolution spectrofluorometry. A study of spectra recorded from cultured Ehrlich ascites (EL2), and Harding Passey melanoma cells (HPM-67 and HPM-73 line) grown under comparable conditions, shows that free NAD(P)H predominates in HPM-67 and EL2, while this coenzyme is bound in HPM-73. The free/bound ratio may be profoundly modifed by chemicals, e.g. in the HPM-73 increase of free and decrease of bound NAD(P)H occurred upon treatment with 10(-6) oligomycin. When atebrine at levels (10(-6) M) below cytotoxicity was added, there was a decrease of the free NAD(P)H spectrum possibly through energy transfer from NAD(P)H to atebrine. Consideration of long range energy transfer i.e., excitation of atebrine by fluorescence of NAD(P)H vs. short range transfer of excitation energy from free NAD(P)H to atebrine, favors the latter mechanism. A transient (reversible) increase in atebrine fluorescence is seen following intracellular microinjection of substrate (e.g. glucose-6-P) leading to an increase in free NAD(P)H. At cytotoxic levels of atebrine (e.g 2 x 10(-5) M) an irreversible increase of atebrine fluorescence is seen. The microspectrofluorometric technique appears therefore well suited to study physiological processes at the level of intracellular coenzymes, as well as possible processes of intermolecular energy transfer in the microenvironment.

    The experimental data presented in the work testify to the cytostatic activity of 1-10 kD polypeptide fractions from brains of the hibernating ground squirrel and the Yakut horse towards Ehrlich ascitic carcinoma (EAC) cells. The experiments on the investigation of the inhibiting influence of 1-10 kD fractions from tissues of the hibernating and cold-adapted animals on protein-synthesizing system of EAC cells allow us to conclude that the cytostatic effect of the fractions is effected at the genetic level in the tumor cells.

    Co-infection of Ehrlich ascites carcinoma (EAC)-bearing mice with Sendai virus and Rous sarcoma virus (RSV) did not result in the formation of complete RSV. Sendai virus could be, however, propagated in this system over 8 serial passages. As demonstrated by immunofluorescence and complement fixation reactions, antigens specific to each virus were synthesized in EAC cells following either single or mixed virus infection. The virus progens also contained antigenic fractions incorporated from the host cell. The incomplete progens synthesized when RSV inoculation preceded that of Sendai virus possessed three polypeptide fractions characteristic of Sendai virus and one RSV-specific fraction.

    The continuous selection for rapid growth has been accompanied by an increasing occurrence of ascites syndrome (AS), which develops in broilers failing to supply the increasing demand for O(2) in their bodies. Moderate heritability has been reported for AS in broiler populations, suggesting that selection against AS is feasible. However, direct selection based on AS mortality requires exposure of candidate birds to AS-inducing conditions (AIC), which hinder selection for performance traits. Noninvasive indicators of AS, expressed under standard husbandry, may facilitate the integration of selection against AS into breeding programs. This study was designed to look for differences in heart rate, hematocrit, O(2) saturation of hemoglobin in arterial blood (SaO(2)), BW, and weight gain, all measured at early ages under standard brooding conditions, between birds that later developed AS and those that remained healthy under AIC, and to estimate the heritability of these AS-related parameters and their genetic correlation with the tendency of broilers to develop AS. The experimental population was derived from a broiler dam line. Male progeny of 34 half-sib sire families were reared under standard brooding conditions to 19 d of age, then under an AIC protocol consisting of housing in individual cages, cool air high-speed ventilation, and growth enhancement using high-energy pelleted feed and 23 h/d of light. Birds were necropsied upon mortality or at the end of the trials and were recorded as being susceptible, with manifestations of AS (SUS), or resistant and healthy (RES). About 44% developed AS, confirming the efficacy of the novel AIC protocol. The SUS and RES chicks did not differ in BW and weight gain up to 19 d of age, suggesting that there was no association between AS susceptibility and rapid early growth. The SUS chicks exhibited lower SaO(2) and heart rate than the RES chicks. Moderate heritability was estimated for all traits, but only SaO(2) exhibited

    The expression of the total proteasome pool, immune proteasome subunits LMP2 and LMP7, TAP1 and TAP2 transporters, as well as RT1A molecule of MHC class I was investigated in the ascite Zajdela hepatoma at the 10th day after implantation into Brattleboro rats with the hereditary defect of hypothalamic arginine-vasopressin synthesis (AVP) and into WAG rats with normal AVP expression. In Zajdela hepatoma cells implanted into Brattleboro rats the 3-fold increase of the total proteasome pool and LMP2 level and 8-fold increase of the LMP7 level was detected by Western blotting as compared to those in WAG rats. Differences in the LMP2 and LMP7 expression suggest variations in their functions, namely the important role of LMP7 in anti-tumor immunity. The growth of Zajdela hepatoma in WAG rats was accompanied by the decreased level of total proteasome pool as well as immune proteasome expression as compared to those in Brattleboro rats during the regression of tumor. The analysis of TAP1 and TAP2 revealed the pronounced expression of these peptide transporters in Zajdela hepatoma cells implanted into Brattleboro and WAG rats. The expression level of RT1A molecule of MHC class I was increased 3 times in Zajdela hepatoma cells implanted into Brattleboro rats as compared to WAG rats. Moreover, flow cytometric analysis of CD4- and CD8-lymphocytes number in the spleen of Brattleboro and WAG rats was performed at the 10th day after implantation of Zajdela hepatoma. The increased number of CD4- and CD8-lymphocytes was observed in the spleen of Brattleboro as compared to WAG. The increased subpopulations of cytotoxic T-lymphocytes and T-helpers might promote the tumor regression in Brattleboro rats. The reduced populations of CD4- and CD8-lymphocytes in the spleen of WAG rats were accompanied by the splenomegaly and tumor progression. The data obtained suggest that AVP deficiency in Brattleboro rats leads to the increase of the immune proteasome and MHC class I expression in

    The synthesis, structure, electrochemistry, and biological studies of Co(II), Ni(II), Cu(II), and Zn(II) complexes of thiocarbohydrazone ligand are described. The ligand is synthesized starting from thiocarbohydrazide and isatin. It is evident from the IR data that in all the complexes, only one part of the ligand is coordinated to the metal ion resulting mononuclear complexes. The ligand coordinates essentially through the carbonyl oxygen of the isatin fragment, the nitrogen atom of the azomethine group, and sulfur atom after deprotonation to give five membered rings. H1 NMR spectrum of the ligand shows only one set of signals for the aromatic protons, while the NH of isatin and NH of hydrazone give rise to two different singlets in the 11–14 ppm range. The formulations, [Cu(L)Cl]·2H2O, [Cu(L)(CH3COO)]·2H2O, [Ni(L)Cl], [Ni(L)(CH3COO)], [Co(L2)], and [Zn(L2)]·2H2O are in accordance with elemental analyses, physical, and spectroscopic measurements. The complexes are soluble in organic solvents. Molar conductance values in DMF indicate the nonelectrolytic nature of the complexes. Copper complex displays quasireversible cyclic voltametric responses with Ep near −0.659 v and 0.504 v Vs Ag/AgCl at the scan rate of 0.1 V/s. Copper(II) complexes show a single line EPR signals. For the observed magnetic moment and electronic spectral data possible explanation has been discussed. From all the available data, the probable structures for the complexes have been proposed. The compounds synthesized in present study have shown promising cytotoxic activity when screened using the in vitro method and at the same time were shown to have good activity when tested using the Ehrlich ascites carcinoma (EAC) model. The antimicrobial screening showed that the cobalt complex possesses enhanced antimicrobial activity towards fungi. PMID:18320020

    To investigate and compare the phenotype and function of lymphocytes collected from patients harboring advanced ovarian cancer, leukocytes from peripheral blood (n = 18), ascitic fluid (n = 13) and tumor tissues (n = 13) were evaluated for the relative proportions of lymphocyte subsets, including CD3+, CD4+, CD8+, CD19+, CD56 and the early (CD25) and late (HLA-DR) activation markers on CD3+ T cells. The ability to synthesize type 1 cytokines (IFN-gamma and IL-2) and a type 2 cytokine (IL-4) was assessed by flow cytometry. In all patients, T cells (CD3+) were the major leukocyte population detected in each tissue, with CD4+ T cells being dominant in peripheral blood lymphocytes (PBL) and tumor-associated lymphocytes (TAL) but not in tumor-infiltrating lymphocytes (TIL) (CD4:CD8 ratios: 3.0 vs. 2.0 vs. 1.0, respectively). CD19+ lymphocytes (B cells) and CD56+ lymphocytes (NK cells) were significantly higher in PBL compared to TAL and TIL (p < 0.05). TAL and TIL had a higher proportion of T cells expressing the late activation marker HLA-DR compared to PBL. In contrast, no significant differences were detected in PBL, TAL and TIL in the expression of the early activation marker CD25. Type 1 cytokines were the dominant type produced by in vitro stimulated T cells for each population, with a greater proportion of IFN-gamma+ T cells in TAL and TIL compared to PBL (p < 0.01), and a higher proportion of IL-2+ T cells in PBL compared with TAL and TIL (p < 0.05). Low percentages of IL-4+ T cells (i.e. Th2) were detected in each tissue. Taken together, these data demonstrate the recruitment and accumulation of high concentrations of antigen-experienced T lymphocytes in TAL and TIL compared to PBL. However, low surface expression of IL-2 receptor (i.e. CD25), as well as depressed intracellular IL-2 production in chronically stimulated TAL and TIL suggests that the impaired antitumor function commonly detected in these lymphocyte populations may be secondary to an acquired

    The objective of this work is to report the antiproliferative effect of P. cupana treatment in Ehrlich Ascites Carcinoma (EAC)-bearing animals. Female mice were treated with three doses of powdered P. cupana (100, 1000 and 2000 mg/kg) for 7 days, injected with 10(5) EAC cells and treated up to day 21. In addition, a survival experiment was carried out with the same protocol. P. cupana decreased the ascites volume (p = 0.0120), cell number (p = 0.0004) and hemorrhage (p = 0.0054). This occurred through a G1-phase arrest (p < 0.01) induced by a decreased gene expression of Cyclin D1 in EAC cells. Furthermore, P. cupana significantly increased the survival of EAC-bearing animals (p = 0.0012). In conclusion, the P. cupana growth control effect in this model was correlated with a decreased expression of cyclin D1 and a G1 phase arrest. These results reinforce the cancer therapeutic potential of this Brazilian plant.

    Hereditary angioedema (HAE) is a rare autosomal dominant disease most commonly associated with defects in C1 esterase inhibitor (C1-INH). HAE manifests as recurrent episodes of edema in various body locations. Atypical symptoms, such as ascites, acute respiratory distress syndrome, and hypovolemic shock, have also been reported. Management of HAE conventionally involves the treatment of acute attacks, as well as short- and long-term prophylaxis. Since attacks can be triggered by several factors, including stress and physical trauma, prophylactic therapy is recommended for patients undergoing surgery. Human plasma-derived C1-INH (pdC1-INH) concentrate is indicated for the treatment of both acute HAE attacks and pre-procedure prevention of HAE episodes in patients undergoing medical, dental, or surgical procedures. We report the first case of a patient with HAE who experienced an abdominal attack precipitated by a retroperitoneal bleed while being converted from warfarin to heparin in preparation for surgery. Subsequently, the patient had a protracted course in hospital with other complications, which included hypovolemic shock, ascites, severe sepsis from nosocomial pneumonia, renal and respiratory failure. Despite intensive interventions, the patient remained in a critical state for months; however, after a trial of daily intravenous infusion of pdC1-INH concentrate (Berinert®, CSL Behring GmbH, Marburg, Germany), clinical status improved, particularly renal function. Therefore, pdC1-INH concentrate may be an effective treatment option to consider for critically-ill patients with HAE.

    Spontaneous bacterial peritonitis (SBP) can be a severe complication occurring in patients with cirrhosis and ascites, with associated mortality often as high as 40%. Traditional diagnostics for SBP rely on culture techniques for proper diagnosis, although recent reports suggest that the presence of bacterial DNA in peritoneal fluid in patients with cirrhosis and ascites is an indicator of SBP. A previously published broad-range PCR (16S PCR) coupled with high-resolution melt analysis (HRMA) was compared with standard culture techniques for diagnosis of SBP in 106 peritoneal fluid samples from patients with suspected SBP. The sensitivity and specificity for 16S PCR for detecting eubacterial DNA compared with those of standard culture techniques were 100% (17/17) and 91.5% (85/89), respectively. Overall, HRMA concordance with species identification was 70.6% (12/17), although the 5 samples that were discordant at the species level were SBP resulting from a polymicrobial infection, and species-level identification for polymicrobial infections is outside the capability of HRMA. Both the broad-range 16S PCR and HRMA analysis provide useful diagnostic adjunctive assays for clinicians in detecting and identifying pathogens responsible for SBP.

    In recent ten years one of the major problems of modern radiobiology is the study of radiation protective mechanisms with the help of different substances as well as activation of internal resources of the organism. Internal resources mean such phenomena as hormesis and adaptive response which represent cell or body reaction on low doses of inducing factors and predetermine their further high dose effect resistance. At present special interest is attracted by studies of biological effects of low-dose-rate high-LET radiation because of searching for new types of radiation for more effective cancer therapy and searching for new methods of radiation protection. Since natural biologically active substances have low toxicity and are capable of affecting physiological processes taking place in human’s organism and increasing organism’s natural defense system, the interest to protective means of vegetal origin and search of special food supplements intensifies every year. The purpose of this study is to investigate the combined influence of food supplement, low dose rate high-LET radiation simulating high-altitude flight conditions and X-ray radiations on radiosensitivity, induction of radiation adaptive response (RAR) and growth of Ehrlich ascite carcinoma as well. Experiments were performed with males of SHK mice at the age of two months. The animals were being irradiated with low-dose-rate high-LET radiation with the dose of 11,6 cGy (0,5 cGy/day) behind the concrete shield of the 70 GeV protons accelerator (Protvino). The X-ray irradiation was carried out on the RTH device with a voltage of 200 kV (1 Gy/min; Pushchino). The diet composition included products containing big amount of biologically active substances, such as: soybeam meat, buckwheat, lettuce leaves and drug of cod-liver oil. Four groups of mice were fed with selected products mentioned above during the whole irradiation period of 22 days. The control groups received the same food without irradiation

    The present investigations should contribute to clarify the importance of beta-adrenergic system in myocard for the triggering of sudden death syndrome and ascites in male broiler chickens. Therefore it should be verified if differences in density of beta-adrenergic receptors in myocard exist in several strains and sexes of chickens. We showed in both male and female broilers that the receptor density was significantly higher as in chickens of the laying strain. There were no significant differences in receptor density between sexes in both investigated strains as well as in KD-values between all groups. The latter finding is referred to the absence of differences in receptor affinity for 3H-dihydroalprenolol between the groups. Clarification of the question if chronic heart failure is in contrast to myocard hypertrophy accompanied with reduction of beta-adrenergic receptor density or receptor affinity in broilers too, as could be shown in other species, has to carried out in further investigations.

    This study examined the effects of dietary DL-2-hydroxy-4(methylthio)butanoic acid (DL-HMTBA) supplementation on growth performance, antioxidant capacity, and ascites syndrome (AS) in broilers reared at low ambient temperature (LAT) from 7 to 28 days of age. Eight hundred 7-day-old broilers were randomly assigned to two ambient temperatures (LAT and normal ambient temperature [NAT]), four supplemental DL-HMTBA levels (0.17, 0.34, 0.51, and 0.68 %) of the basal diet in a 2 × 4 factorial arrangement (ten replicate pens; ten birds/pen). LAT and NAT indicate temperatures of 12-14 and 24-26 °C in two chambers, respectively, and broilers were reared at these temperatures from 7 to 28 days of age.

The optimal supplemental DL-HMTBA levels in basal diet of broilers aged from 7 to 28 days under low or normal temperatures were similar, so the authors recommended supplemental of DL-HMTBA level was 0.46 %.

    This study examined the effects of dietary DL-2-hydroxy-4(methylthio)butanoic acid (DL-HMTBA) supplementation on growth performance, antioxidant capacity, and ascites syndrome (AS) in broilers reared at low ambient temperature (LAT) from 7 to 28 days of age. Eight hundred 7-day-old broilers were randomly assigned to two ambient temperatures (LAT and normal ambient temperature [NAT]), four supplemental DL-HMTBA levels (0.17, 0.34, 0.51, and 0.68 %) of the basal diet in a 2 × 4 factorial arrangement (ten replicate pens; ten birds/pen). LAT and NAT indicate temperatures of 12-14 and 24-26 °C in two chambers, respectively, and broilers were reared at these temperatures from 7 to 28 days of age. LAT significantly decreased body weight gain (P < 0.001), serum glutathione (GSH) content (day 14, P = 0.02; day 28, P = 0.045), glutathione peroxidase (GSH-Px) activity, and total antioxidant capacity (T-AOC) at 21 days (P = 0.001, 0.015) and 28 days (P = 0.017, 0.010) and increased feed conversion ratio (FCR) (P < 0.001), serum malondialdehyde (day 21, P = 0.000) and protein carbonyl Level (day 14, P = 0.003; day 21, P = 0.035).

    Recently, a unique clinicopathologic variant of multicentric Castleman's disease (MCD) has been identified in Japan. This disease is characterized by a constellation of symptoms, as listed in the title, and multiple lymphadenopathy of mild degree with a pathologic diagnosis of atypical CD, often posing diagnostic and therapeutic problems for pathologists and hematologists, respectively. These findings suggest that this disease represents a novel clinical entity belonging to systemic inflammatory disorders with a background of immunological abnormality beyond the ordinal spectrum of MCD. To define this disorder more clearly, Japanese participants presented clinicopathologic data at the Fukushima and Nagoya meetings. Many of the patients presented by the participants were significantly accompanied by a combination of thrombocytopenia, ascites (anasarca), pleural effusions, microcytic anemia, fever, myelofibrosis, renal dysfunction, and organomegaly (TAFRO). Multiple lymphadenopathies were generally of mild degree, less than 1.5 cm in diameter, and consistently featured the histopathology of mixed- or less hyaline vascular-type CD. Autoantibodies were often detected. However, this disease did not fulfill the diagnostic criteria for well-known autoimmune diseases including systemic lupus erythematosus. Castleman-Kojima disease and TAFRO syndrome (the favored clinical term) were proposed for this disease. The patients were sensitive to steroid and anti-interleukin-6 receptor antibody (tocilizumab), but some exhibited a deteriorated clinical course despite the treatment. The participants proposed a future nationwide survey and a Japanese consortium to facilitate further clinical and therapeutic studies of this novel disease. [J Clin Exp Hematop 53(1): 57-61, 2013].

    Rapidly increasing malignant neoplastic disease demands immediate attention. Several dietary compounds have recently emerged as strong anti-cancerous agents. Among, Bromelain (BL), a protease from pineapple plant, was used to enhance its anti-cancerous efficacy using nanotechnology. In lieu of this, hyaluronic acid (HA) grafted PLGA copolymer, having tumor targeting ability, was developed. BL was encapsulated in copolymer to obtain BL-copolymer nanoparticles (NPs) that ranged between 140 to 281nm in size. NPs exhibited higher cellular uptake and cytotoxicity in cells with high CD44 expression as compared with non-targeted NPs. In vivo results on tumor bearing mice showed that NPs were efficient in suppressing the tumor growth. Hence, the formulation could be used as a self-targeting drug delivery cargo for the remission of cancer.

    The objective of the current study was to compare the changes in a fitness trait when selection is performed for 5, 10, and 20 generations on a production trait that influenced its expression. Responses to single-trait selection for growth based on phenotype or animal model predictions were compared by computer simulation. Two-trait index selection was performed when a trait, related to the fitness trait, was included in the index with the production trait. The phenotypic expression of the fitness trait among the sibs was also considered as a selection factor for single-trait and two-trait index selection. For a fixed increase in the expression of the fitness trait, mass selection produced a larger increase in the production trait than did use of standard animal model best linear unbiased prediction under single-trait selection. The reduction in the genotypic mean of the fitness trait was accompanied by an increase in its phenotypic expression. The use of sib information and an indicator trait reduced the level of expression reached by the fitness trait.

    Abdominal pseudocyst formation is a rare adult complication associated with ventriculoperitoneal (VP) shunts. Presenting symptoms are primarily abdominal and include distention, pain and anorexia, and secondarily neurological with signs and symptoms of shunt malfunction. We describe a case of VP shunt-related pseudocyst formation presenting as symptomatic pelvic organ prolapse with stage 4 enterocele 4 years after VP shunt placement. The patient's vaginal enterocele enlarged and became more symptomatic as intra-abdominal cyst formation expanded. Symptomatic relief of pelvic floor symptomatology including resolution of exteriorized prolapse was established by conservative measures and eventual VP shunt revision and removal. VP shunt malfunction may present as symptomatic pelvic organ prolapse and may require shunt removal or revision for resolution of symptoms.

    Crimean-Congo hemorrhagic fever (CCHF) is a fatal systemic viral infection which is an important health problem in Turkey. Many systemic symptoms have been reported including fever, hemorrhage, headache, fatigue, muscle ache, abdominal pain, nausea and vomiting. A 45-year-old male farmer with CCHF presented with massive peritoneal effusion and hyperbilirubinemia. To our knowledge, this is the first case of peritoneal effusion and hyperbilirubinemia in an adult patient with CCHF. His clinical symptoms successfully improved with supportive therapy. In patients who live in endemic areas with atypical presentation for the diagnosis of CCHF should be kept in mind.

    We evaluated the preventive and therapeutic effects of aqueous suspensions of garlic, tomato, and garlic + tomato in the development of experimental Ehrlich tumors in mice. The aqueous suspensions (2%) were administered over a short term for 30 days before tumor inoculation and 12 days afterward, and suspensions at 6% were administered for 180 days before inoculation and for 12 days afterward. The volume, number, and characteristics of the tumor cells and AgNOR counts were determined to compare the different treatments. Aqueous 6% suspensions of garlic, tomato, and garlic + tomato given over the long term significantly reduced tumor growth but when given over the short term, they did not alter tumor growth.

    A 75-year old man had been diagnosed at 42 years of age as having polycythemia vera and had been monitored at another hospital. Progression of anemia had been recognized at about age 70, and the patient was thus referred to our center in 2008 where secondary myelofibrosis was diagnosed based on bone marrow biopsy findings. Hematemesis due to rupture of esophageal varices occurred in January and February of 2011. The bleeding was stopped by endoscopic variceal ligation. Furthermore, in March of the same year, hematemesis recurred and the patient was transported to our center. He was in irreversible hemorrhagic shock and died. The autopsy showed severe bone marrow fibrosis with mainly argyrophilic fibers, an observation consistent with myelofibrosis. The liver weighed 1856 g the spleen 1572 g, indicating marked hepatosplenomegaly. The liver and spleen both showed extramedullary hemopoiesis. Myelofibrosis is often complicated by portal hypertension and is occasionally associated with gastrointestinal hemorrhage due to esophageal varices. A patient diagnosed as having myelofibrosis needs to be screened for esophageal/gastric varices. Myelofibrosis has a poor prognosis. Therefore, it is necessary to carefully decide the therapeutic strategy in consideration of the patient’s concomitant conditions, treatment invasiveness and quality of life. PMID:22851873

    Cirrhotic patients (CPs) are susceptible to spontaneous bacterial peritonitis (SBP). Aim of this study was to examine if this susceptibility was related to peritoneal macrophages' (PMs) altered host defence. Absorbance of phagocytosed particles by PMs from CPs was lower than that of control (31.88% vs. 77.2%). Particle opsonisation increased the absorbance to 41% in CPs' PMs, and this value remains lower than the control; 77.2%. Respiratory burst (RB) was expressed as fluorescence index values, and these were higher in PMs from CPs than in controls (82 vs. 41, 73 vs. 26 and 71 vs. 26). IFN-γ made no further increase of RB values in PMs from CPs. CD14 expression was also higher in CPs' PMs. IFN-γ significantly downregulated CD14 expression in both CPs' PMs and control. Reduced phagocytosis by predominantly CD14-positive PMs from CPs could be related to intense RB. Findings suggest altered host defence that could contribute to susceptibility to SBP. PMID:24371553

    1. The steady-state tracer exchange flux of chloride was measured at 10-150 mM external chloride concentration, substituting either lactate or sucrose for chloride. The chloride flux saturates in both cases with a K 1/2 about 50 and 15 mM, respectively. 2. The inhibitory effect of other monovalent anions on the chloride transport was investigated by measuring the 36Cl- efflux into media where either bromide, nitrate, or thiocyanate had been substituted for part of the chloride. The sequence of increasing affinity for the chloride transport system was found to be: Br- less than Cl- less than SCN- = NO3-. 3. The chloride steady-state exchange flux in the presence of nitrate can be described by Michaelis-Menten kinetics with nitrate as a competitive inhibitor of the chloride flux. 4. The apparent activation energy (EA) was determined to be 67 +/- 6.2 kJ/mole, and was constant between 7 and 38 degrees C. 5. The membrane potential (Vm) was measured as a function of the concentration of external K+, substituting K+ for Na+. The transference number of K+ (tK) was estimated from the slope of Vm vs. log10 (K+)e, and tCl and tNa were calculated, neglecting current carried by ions other than Cl-, K+, and Na+. The diffusional net flux of K+ was calculated from the steady-state exchange flux of 42K+, assuming the flux ratio equation to be valid. From this value the K+ conductance and the Na+ and Cl- conductances were calculated. The experiments showed that GCl, GNa, and GK are all about 14 muS/cm2. 6. The net (conductive) chloride permeability derived from the chloride conductance was 4 x 10(-8) cm/sec compared with the apparent permeability of 6 x 10(-7) cm/sec as calculated from the chloride tracer exchange flux. These data suggest that about 95% of the chloride transport is mediated by an electrically silent exchange diffusion. 7. Comparable effects of phloretin (0.25 mM) on the net (conductive) permeability and the apparent permeability to chloride (about 80% inhibition) may indicate that the chloride exchange and conductance pathways are not completely separate and distinct modes of transport, but may involve common elements. The reduced chloride permeability in the presence of phloretin is estimated to be two orders of magnitude larger than the ground permeability of the cell membrane. PMID:529133

    Experiments were performed to ascertain the degree to which the amount of amino acids might be one of the regulatory factors that control the activity of the nucleolar RNA polymerase. Assays of the enzymatic activity were done with isolated nuclei from cells incubated with low and high concentrations of amino acids. Soon after the cells were exposed to a medium enriched in amino acids, a rapid increase of nucleolar RNA polymerase activity occurred. A similar result was obtained in cells incubated with lower concentrations of amino acids. However, the rate of ribosomal RNA synthesized was regularly much higher in cells incubated in a medium enriched with amino acids than in a medium low in amino acids. Apparently, the amino acids only controlled ribosomal RNA synthesis. Thus, neither maturation, processing, and transport of nuclear precursors into cytoplasmic ribosomal RNA, nor the synthesis of rapidly labeled RNA was affected. PMID:4108870

    Isoproterenol (IPN)-stimulated activity of adenylate cyclase was enhanced in a dose-dependent manner by exposure of AH130 cells to mitomycin C (MMC). The enhancement was also observed in prostaglandin E1-, guanine nucleotide analog-, NaF-, cholera toxin- and forskolin-stimulated activities of the enzyme but not in manganese-stimulated activity. In addition, even when the cells pretreated with islet-activating protein were exposed to MMC, IPN-stimulated activity of adenylate cyclase was enhanced. Anaerobic exposure of AH130 cells to MMC somewhat inhibited IPN-stimulated activity of adenylate cyclase in contrast with aerobic exposure. Exposure of cells to adriamycin also caused enhancement of IPN-stimulated activity of adenylate cyclase but exposure to nitrogen mustard inhibited the enzyme stimulation by IPN. The enhancing effect of MMC was lost by the combined treatment with alpha-tocopherol. From these results, it was shown that MMC modulated the activity of adenylate cyclase, probably through alterations in membrane structure.

    The purpose of this study was to assess mitochondrial function and glutathione (a mitochondrial antioxidant) in response to oxidative stress in mitochondria in vitro obtained from broilers with and without pulmonary hypertension syndrome (PHS). Liver mitochondria from Control and PHS broilers were incubated with 0, 1, and 5-mM tertiary-butyl hydroperoxide (tBH). Indices of mitochondrial function [the respiratory control ratio (RCR) and the adenosine diphosphate to oxygen ratio (ADP:O)], and levels of mitochondrial and extra-mitochondrial reduced (GSH) and oxidized (GSSG) glutathione, cysteine, cystine, glutamate and cysteinyl-glycine were determined following tBH treatment. Lower RCR and ADP:O values were observed in PHS mitochondria than in controls. Whereas control mitochondria remained coupled (RCR > 2.0), only 3 PHS preparations remained coupled after 60 min of incubation with 5 mM tBH, indicating a greater susceptibility to oxidative stress in PHS mitochondria. The lower RCR in PHS mitochondria was due to increased oxygen consumption during State IV respiration. Oxidative stress following tBH treatment (decreased GSH and increased GSSG) was observed, but there were no differences in GSH or GSSG between control and PHS mitochondria. The PHS mitochondria did exhibit elevated mitochondrial and extramitochondrial cystine than controls, however. The results indicate that PHS mitochondria do not lack antioxidant protection from GSH, but lower RCR and ADP:O ratios in PHS mitochondria indicate a dysfunction that may contribute to the pathophysiology of this metabolic disease in broilers.

    Methyl 2-nitroimidazole-1-acetohydroxamate (KIN-804) is a 2-nitroimidazole derivative containing a hydroxamate side chain designed to enhance the radiosensitization response of hypoxic cells. The possible sensitization of tumor tissue by KIN-804 can be evaluated through investigation of the levels of the free radical scavengers; namely, glutathione (GSH) and its complex enzyme system including glutathione reductase (GR) and glutathione peroxidase (GSH-Px), as well as glucose-6-phosphate dehydrogenase (G-6-PD). Female albino mice were inoculated with Ehrlich carcinoma in the thigh. Administration of KIN-804 (i.p. 80 mg/kg body weight) was carried out 20 min before localized irradiation of 10 Gy. The data revealed that KIN-804 administration, followed or not by gamma irradiation, resulted in a significant decrease in GSH content in tumor tissues associated with inhibition in GR and G-6-PD activities. Blood GSH-Px was enhanced in tumor inoculated mice and the administration of KIN-804 returned it to the normal value. These changes were more noticeable in tumor bearing mice exposed to both KIN-804 and irradiation.

    Despite the remarkable anti-tumor activity of doxorubicin (DOX), its clinical application is limited due to multiple organ toxicities. Products with less side effects are therefore highly requested. The current study investigated the anti-cancer activities of vanillin against breast cancer and possible synergistic potentiation of DOX chemotherapeutic effects by vanillin. Vanillin (100mg/kg), DOX (2mg/kg) and their combination were administered i.p. to solid Ehrlich tumor-bearing mice for 21days. MCF-7 human breast cancer cell line was treated with vanillin (1 and 2mM), DOX (100μM) or their combination. Protection against DOX-induced nephrotoxicity was studied in rats that received vanillin (100mg/kg, ip) for 10days with a single dose of DOX (15mg/kg) on day 6. Vanillin exerted anticancer effects comparable to DOX and synergesticlly potentiated DOX anticancer effects both in-vivo and in-vitro. The anticancer potency of vanillin in-vivo was mediated via apoptosis and antioxidant capacity. It also offered an in-vitro growth inhibitory effect and cytotoxicity mediated by apoptosis (increased caspase-9 and Bax:Bcl-2 ratio) along with anti-metasasis effect. Vanillin protected against DOX-induced nephrotoxicity in rats. In conclusion, vanillin can be a potential lead molecule for the development of non-toxic agents for the treatment of breast cancer either alone or combined with DOX.

    Veno-occlusive disease (VOD), or sinusoidal obstruction syndrome, is a well-recognised, serious complication associated with the chemotherapy conditioning therapy used in hematopoietic stem cell transplantation (HSCT). Fluid management is typically challenging in children with this condition. We describe effective early use of peritoneal dialysis catheters to drain extravascular, intra-abdominal fluid in children with VOD, allowing intravascular fluid administration to preserve renal perfusion and function, preventing multi-organ dysfunction. All but one of the children are long-term survivors, both of their significant VOD and their HSCT. The child that did not survive died from their underlying metabolic illness, not VOD.

    Bacterial translocation occurs in ascitic cirrhotic rats, but its association with ascites infection is unknown. The aim of this study was to assess the relation between bacterial translocation and ascites infection in cirrhotic rats. Male Sprague-Dawley rats were induced to cirrhosis with intragastric CCl4. Ascitic fluid, portal and peripheral blood, mesenteric lymph nodes, liver and spleen samples were cultured before death in those cirrhotic rats with less (group A) or more (group B) than 250 polymorphonuclear neutrophils/mm3 in ascitic fluid, as well as in healthy control rats. Histological examination of jejunum, ileum, and caecum was also performed. Bacterial translocation occurred in 45% of ascitic rats (without differences between groups A and B), but in 0% controls (p = 0.01). Bacterial translocation was associated with positive ascitic fluid culture in 60% of the cases. In all of them the same bacterial species was isolated in both mesenteric lymph node and ascitic fluid. Submucosal caecal oedema (100%), ileal lymphangiectasia (41%), and caecal inflammatory infiltrate (41%) occurred in ascitic rats, the last being associated with ascitic fluid positive culture (p = 0.04). These results suggests that bacterial translocation occurs frequently in ascitic cirrhotic rats, and may play a permissive, but not unique, part in a number of ascites infections. Whether histological changes seen in cirrhotic ascitic rats favour bacterial translocation remains to be elucidated. Images Figure 1 PMID:7828991

    1. This study compared the effect of dietary supplementation with organic or inorganic selenium (Se) sources plus control amounts or large amounts of vitamin E (alpha-tocopherol acetate) in broilers raised at control (20 to 24 degrees C) or low (14.5 to 16.8 degrees C) temperatures after 2 weeks of age. 2. The following dietary treatments were used from one day old. Diet 1, the control diet, comprised a commercial diet containing 0.15 mg/kg inorganic Se and 50 mg vitamin E/kg feed. Diet 2 was the same as diet 1, supplemented with 0.15 mg/kg inorganic Se. Diet 3 was the same as diet 2 but was supplemented with 200 mg/kg vitamin E. Diet 4 was the same as diet 1, but inorganic Se was replaced with 0.30 mg/kg organic Se. Diet 5 was the same as diet 4, supplemented with 200 mg/kg vitamin E. 3. Low temperature reduced the growth rate of broilers; however, at 6 weeks, there were no differences in the body weights of birds fed on organic Se supplemented diets housed at low or control temperature. The feed conversion ratio was significantly affected by low temperature but not by diet. The heterophil/lymphocyte ratio was higher in chicks after one week in the cold, indicating mild stress. Blood triiodothyronine levels were significantly higher in birds after 1 and 4 weeks in the cold but thyroxin was not affected. 4. Organic Se supplementation increased relative lung weight at the control temperature, which might lead to greater respiratory capacity. Relative spleen weight significantly decreased in broilers fed diets supplemented with inorganic Se under cold conditions, a possible indication of chronic oxidative stress. 5. At the low temperature, supplementation with organic Se alone, or with inorganic Se and vitamin E increased glutathione peroxidase (GSHPx) activity and glutathione (GSH) concentration in the liver of broilers, which may indicate increased activity of birds' antioxidant defence against suboptimal environments.

    A 35-year-old male patient suffering from dyspnoea on effort for 8 months, with abdominal and jugular venous distension, was previously studied in another hospital and discharged with a diagnosis of restrictive cardiomyopathy. Physical examination revealed a blood pressure of 110/60 mm Hg and absence of pericardial knock and also of paradoxical pulse. Chest X-ray showed no cardio-pulmonary alterations. Transthoracic echocardiography showed mild LV dysfunction (LVEF 46%) and lack of pericardial effusion and thickening. Doppler interrogation of transmitral flow showed a restrictive pattern. Computed tomography showed diffusely thickened pericardium, with the absence of calcification and of pericardial effusion. Cardiac magnetic resonance confirmed pericardial thickening and showed lack of myocardial alterations. Mild LV dysfunction was noted with dyskinesia of interventricular septum. The patient underwent cardiac catheterization, demonstrating an equalisation of RV and LV diastolic pressures with "square root" sign. The patient underwent pericardiectomy with consequent resolution of his symptoms and improvement of LV function.

    We present the case of a 34-year-old woman with haemorrhagic ascites and an extrinsic rectal mass on endoscopy. Endometrioma was subsequently confirmed by laparoscopy and biopsy. Intestinal endometriosis is common, and often mimics other gastrointestinal pathology. Haemorrhagic ascites or intestinal masses are rare presentations of endometriosis, and this is the only reported case of both occurring together. Endometriosis and ascites are more common in women of African descent, and although histological diagnosis requires laparoscopy, MRI has a high negative predictive value; 95% for intestinal endometriosis. Re-accumulation of ascites were prevented by starting a gonadotrophin antagonist. PMID:24717582

    Cirrhosis is a frequent and severe disease, complicated by renal sodium retention leading to ascites and oedema. A better understanding of the complex mechanisms responsible for renal sodium handling could improve clinical management of sodium retention. Our aim was to determine the importance of the amiloride-sensitive epithelial sodium channel (ENaC) in collecting ducts in compensate and decompensate cirrhosis. Bile duct ligation was performed in control mice (CTL) and collecting duct-specific αENaC knockout (KO) mice, and ascites development, aldosterone plasma concentration, urinary sodium/potassium ratio and sodium transporter expression were compared. Disruption of ENaC in collecting ducts (CDs) did not alter ascites development, urinary sodium/potassium ratio, plasma aldosterone concentrations or Na,K-ATPase abundance in CCDs. Total αENaC abundance in whole kidney increased in cirrhotic mice of both genotypes and cleaved forms of α and γ ENaC increased only in ascitic mice of both genotypes. The sodium chloride cotransporter (NCC) abundance was lower in non-ascitic KO, compared to non-ascitic CTL, and increased when ascites appeared. In ascitic mice, the lack of αENaC in CDs induced an upregulation of total ENaC and NCC and correlated with the cleavage of ENaC subunits. This revealed compensatory mechanisms which could also take place when treating the patients with diuretics. These compensatory mechanisms should be considered for future development of therapeutic strategies.

    Primary gastric mantle cell lymphoma is a rare form of gastointestinal tumour. Although peritoneal carcinomatosis accompanied by malignant ascites is relatively common, mantle cell lymphoma presenting with ascites is rare. Also, effusions involving pericardial and pleural cavities are uncommon during the course of lymphomas. We report the first case in which pericardial, pleural and peritoneal effusion of a primary gastric mantle cell lymphoma.

    1989-01-01

    The definitive diagnosis of spontaneous bacterial peritonitis is made by a positive ascitic fluid culture. Causative organisms cannot be isolated in up to 65% of patients with well-defined spontaneous bacterial peritonitis, probably due to inadequate ascites culture techniques. We prospectively compared two ascites culture methods: conventional (on chocolate agar and thioglycolate broth) and modified (inoculation of 10 ml of ascites in a tryptic soy broth blood culture bottle at the patient's bedside). In a 10-month period, 31 cirrhotic patients met our diagnostic criteria for spontaneous bacterial peritonitis; both culture methods were performed on their ascitic fluid. The conventional method grew bacteria in only 16 of the 31 episodes (52%), whereas the modified method grew bacteria in 25 (81%), a significantly higher sensitivity (P less than 0.05). The modified method also shortened significantly the time for detection of bacterial growth. We conclude that ascites inoculation into a blood culture bottle at the patient's bedside should be the routine method for ascites culture. PMID:2685014

    The diaphragm peritoneum from 12 operated patients and 34 patients who died from liver cirrhosis with or without ascites was studied by means of light microscopy and electron transmission and scanning microscopy. Considerable lesions are found in the peritoneum: cuboidization of mesothelial cells, basal membrane thickening, dilation of stomata, lymphatic lacunae and collectors lumina. Liver cirrhosis with ascites is frequently followed by lymphatic vessels thrombosis and firm attachment of the diaphragm to the liver resulting in the inhibition of the ascitic liquid elimination. Thus both the enhancement of liquid transudation into the abdominal cavity and the disturbance of the drainage function of the diaphragm peritoneum take place.

    Abdominal paracentesis is frequently performed in the clinical setting. Every newly developed ascites need to be investigated by abdominal paracentesis. Any clinical or biological deterioration in patients with chronic ascites also requires a new paracentesis. Therapeutically abdominal paracentesis is performed for refractory or symptomatic ascites. As other invasive procedures, it is critical to master its indications, contra-indications and complications. The aim of this article is to review the basics of abdominal paracentesis in order to help physicians to carry out this technical skill.

    The production of ascitic fluid and splenomegaly on intraperitoneal injection in weanlings was used as a test for microsporidia after introduction by other routes and in other loci. Oral and cerebral administration was followed only by enlarged spleens which reproduced the ascitic response on passage. Microsporidia were demonstrable by phase microscopy in all fluids. Positive findings were also obtained with liver, kidney, brain, lungs, blood, and urine. Intramuscular and intranasal injection were occasionally followed by ascites, but splenomegaly again predominated. The results of contact experiments indicated that the organisms were not readily communicable either in weanlings or nurslings. Relation of the microsporidian to Encephalitozoon cuniculi (Nosema cuniculi Lainson et al.) is discussed.

    1989-05-01

    Hepatic hydrothorax is a complication in approximately 5% of patients with cirrhosis. Ascites is almost always present and helps to suggest the correct diagnosis. However, when ascites is absent, radionuclide imaging has proven to be helpful in establishing that the pleural effusion originated from ascitic fluid. When pleural fluid is rapidly removed, such as by thoracostomy tube drainage, the radioisotope may accumulate outside the thorax and produce a negative scan of the chest. When the radionuclide scan is nondiagnostic and the pleural space is being rapidly drained, the pleural fluid collecting system should always be imaged before rejecting a diagnosis of hepatic hydrothorax.

    The quality control of murine hybridoma secretory products has been performed using two approaches for isoelectric focusing affinity immunoblot analysis: (1) a method in which antigen-coated nitrocellulose is placed on top of an acrylamide gel containing isoelectrically focused ascites to bind the antigen specific monoclonal antibody; and (2) a method in which focused ascite proteins were passively blotted onto nitrocellulose and specific monoclonal antibodies were detected with enzyme-conjugated antigen. Analysis by both methods of batches of ascites containing antihuman IgG antibodies that were produced by six hybridomas permitted effective monitoring of immunoreactive antibodies for pI microheterogeneity.

    Budd-Chiari syndrome (BCS) is a rare disease defined by congestive hepatopathy with obstruction of the hepatic venous outflow tract. Classical symptoms and signs include ascites, hepatomegaly, abdominal pain and various degrees of liver dysfunction. BCS is predominantly caused by thrombosis, malformations and venous compression. We present a case, in which BCS was the cause of liver cirrhosis complicated with refractory ascites and which can be misinterpreted as hepatocellular carcinoma nodules. The diagnosis was confirmed during the transjugular intrahepatic portosystemic shunt procedure with successful vascular stenting resolving the ascites formation.

    Transjugular intrahepatic portosystemic shunt creation is a well-established therapy for refractory variceal bleeding and refractory ascites in patients who do not tolerate repeated large volume paracentesis. Experience and technical improvements including covered stents have led to improved TIPS outcomes that have encouraged an expanded application. Evidence for other less frequent indications continues to accumulate, including the indications of primary prophylaxis in patients with high-risk acute variceal bleeding, gastric and ectopic variceal bleeding, primary treatment of medically refractory ascites, recurrent refractory ascites following liver transplantation, hepatic hydrothorax, hepatorenal syndrome, Budd-Chiari syndrome, and portal vein thrombosis. Treatment of patients with high-risk acute variceal bleeding with early TIPS and using transjugular intrahepatic portosystemic shunts as a primary therapy rather than large volume paracentesis for refractory ascites would likely be the 2 circumstances that permit expansion in the frequency of TIPS procedures. The remaining populations discussed above are relatively rare.

    We present a patient with lymphedema that developed after orthotopic liver transplantation. The cause of the posttransplant lymphedema was likely related to a developmental abnormality of the lymphatic system that was exaggerated by refractory chylous ascites. A peritoneal fluid with a milky appearance, chylous ascites is rich in triglyceride and is caused by the obstruction or disruption of abdominal lymphatic channels. It is a rare complication that may develop after trauma or abdominal surgery or as a result of a malignant disease, and it is even more uncommon after liver transplantation. Therapy for chylous ascites involves treating its underlying cause. In the patient we describe, lymphedema tarda, which was diagnosed 6 months after liver transplantation, was likely caused by chylous ascites and a developmental abnormality of the lymphatic system.

    There has been considerable interest in the role of serotonin (5-hydroxytryptamine, 5-HT) in the pathogenesis of pulmonary hypertension due to episodes of primary pulmonary hypertension in humans linked to serotoninergic appetite-suppressant drugs. In this study, we investigated the effect of 5-HT on the development of pulmonary hypertension induced by injecting bacterial lipopolysaccharide (LPS; endotoxin) and cellulose microparticles intravenously, using the nonselective 5-HT(1/2)receptor, antagonist methiothepin. In Experiment 1, broilers selected for ascites susceptibility or resistance under conditions of hypobaric hypoxia were treated with methiothepin or saline, followed by injection of LPS, while recording pulmonary arterial pressure (PAP). In Experiment 2 ascites-susceptible broilers were treated with methiothepin or saline, followed by injection of cellulose microparticles, while recording PAP. In Experiment 3, an i.v. microparticle injection dose shown to cause 50% mortality was injected into ascites-susceptible and ascites-resistant broilers after methiothepin or saline treatment. Injecting methiothepin reduced PAP below baseline values in ascites-susceptible and ascites-resistant broilers, suggesting a role for 5-HT in maintaining the basal tone of the pulmonary vasculature in broilers. Injecting microparticles into the wing vein had no affect on the PAP in the broilers treated with methiothepin, suggesting that 5-HT is an important mediator in the pulmonary hypertensive response of broilers to microparticles. Furthermore, injecting an 50% lethal dose of microparticles into ascites-susceptible and ascites-resistant broilers pretreated with methiothepin resulted in reduced mortality. Serotonin appears to play a less prominent role in the pulmonary hypertensive response of broilers to intravenously injected LPS, indicating that other mediators within the innate response to inflammatory stimuli may also be involved. These results are consistent with our

    Seven patients with small volume ovarian carcinoma, remaining after conventional therapy with surgery and a platinum containing chemotherapy regimen, were treated with intraperitoneal monoclonal antibody guided radiotherapy. 100 mCi131I conjugated to 10 mg of monoclonal antibody were injected i.p. in 2,000 ml peritoneal dialysis fluid. Patients were evaluated 3 months later; 3 had clinical progressive disease while third look laparotomy demonstrated progressive disease in 3 of the remaining 4 patients. The seventh patient did not have a third look laparotomy and is currently inevaluable for response. Five patients with recurrent malignant ascites not controlled by diuretics or repeated paracentesis were similarly treated with 75-170 mCi131I conjugated to 10 mg monoclonal antibody. In three patients the ascites was controlled for a mean of 4 months. One patient died too early to assess the control of his ascites but tumour cells disappeared from the ascitic fluid after therapy. In the patient whose ascites were not controlled, a subpopulation of antigen-negative tumour cells was demonstrated. This study was unable to demonstrate a therapeutic benefit for i.p. injected monoclonal antibody guided radiotherapy for solid intraperitoneal tumour but suggests that it may be capable of controlling the accumulation of antigen positive malignant ascites.

    Pseudo-Meigs' syndrome is used to describe cases of ascites and/or pleural effusion associated with ovarian neoplasms other than benign tumors, which improve after removal of the ovarian lesion. We present three cases of pseudo-Meigs' syndrome secondary to ovarian metastasis from colorectal cancer. In case 1, the patient has severe dyspnea and hypoxia due to massive right pleural effusion; therefore preoperative thoracic drainage was needed. In case 2, the patient needed paracentesis every two or three days to improve abdominal distension. After two courses of 5-fluorouracil, levofolinate, and oxaliplatin (mFOLFOX6), her ascites could be controlled by diuretics without aspiration and her general condition improved. Then she underwent operation. In case 3, the patient developed a massive pleural effusion and ascites coincident with a rapid enlargement of ovarian tumor after resection and adjuvant chemotherapy for rectal cancer. In all cases, pleural effusions and/or ascites resolved and general conditions and daily activities of the patients improved after oophorectomy. They are all currently in good health without recurrence of pleural effusion or ascites. In patients with suspected pseudo-Meigs' syndrome secondary to ovarian metastasis of colorectal cancer, operation including oophorectomy may reduce pleural effusions and/or ascites and improve the general condition.

    Background: The natural history of fulminant hepatic failure (FHF) without liver transplantation is not well known. Aims: To study the natural history and prognostic factors, especially the presence of ascites and spontaneous bacterial peritonitis (SBP), in children with FHF. Methods: FHF was defined by the onset of encephalopathy within 12 weeks of onset of jaundice. From August 1997 to December 2000, 67 children (≤12 years) were diagnosed with FHF. Their clinical features, investigations and outcome were noted. Viral markers A to E (IgM, anti-HAV; IgM, anti-HEV, HBsAg, and anti-HCV) were determined by ELISA. SBP was defined by the presence of ≥250 neutrophils with or without a positive culture in ascitic fluid. Results: Mean age of the children was 5.8 years with an almost equal sex distribution. Viral markers were positive in 63 (94%) cases: hepatitis A in 34 (54%), E in 17 (27%), A+E in seven (11%), and B in five (8%). Thirty one children presented with grade I or II encephalopathy and all recovered, whereas 17 of 36 children who had grade III or IV encephalopathy died. Ascites was detected (both clinically and ultrasonically) in 34 (51%) cases, nine (26%) of which had SBP. Overall mortality was 25%. Mortality was higher in those who had ascites than in those who did not (32% v 18%); among those with ascites it was maximum in those who had SBP (78% v 16%). Total serum bilirubin and grade of encephalopathy were significantly higher, serum albumin was significantly lower, and prothrombin time was significantly prolonged in those who died than in those who recovered. Conclusion: The natural history of FHF in Indian children depends on age, grade of encephalopathy, ascites, and SBP. SBP depicts worse outcome. In all cases of FHF with ascites, the presence of SBP should be investigated. PMID:12089125

    Background The management of ascites can be problematic. This is especially true in patients with diuretic refractory ascites who develop a tense abdomen. This often results in hypotension and decreased venous return with resulting renal failure. In this paper, we further examine the risks and benefits of utilizing an indwelling peritoneal catheter to remove large-volume ascites over a 72-h period while maintaining intravascular volume and preventing renal failure. Methods We retrospectively reviewed charts and identified 36 consecutive patients undergoing continuous large-volume paracentesis with an indwelling peritoneal catheter. At the time of drain placement, no patients had signs or laboratory parameters suggestive of spontaneous bacterial peritonitis. The patients underwent ascitic fluid removal through an indwelling peritoneal catheter and were supported with scheduled albumin throughout the duration. The catheter was used to remove up to 3 L every 8 h for a maximum of 72 h. Regular laboratory and ascitic fluid testing was performed. All patients had a clinical follow-up within 3 months after the drain placement. Results An average of 16.5 L was removed over the 72-h time frame of indwelling peritoneal catheter maintenance. The albumin infusion utilized correlated to 12 mg/L removed. The average creatinine trend improved in a statistically significant manner from 1.37 on the day of admission to 1.21 on the day of drain removal. No patients developed renal failure during the hospital course. There were no documented episodes of neutrocytic ascites or bacterial peritonitis throughout the study review. Conclusion Large-volume peritoneal drainage with an indwelling peritoneal catheter is safe and effective for patients with tense ascites. Concomitant albumin infusion allows for maintenance of renal function, and no increase in infectious complications was noted. PMID:27802853

  10. The peritoneal macrophage inflammatory profile in cirrhosis depends on the alcoholic or hepatitis C viral etiology and is related to ERK phosphorylation

    2012-01-01

    Background The development of ascites in cirrhotic patients generally heralds a deterioration in their clinical status. A differential gene expression profile between alcohol- and hepatitis C virus (HCV)-related cirrhosis has been described from liver biopsies, especially those associated with innate immune responses. The aim of this work was to identify functional differences in the inflammatory profile of monocyte-derived macrophages from ascites in cirrhotic patients of different etiologies in an attempt to extrapolate studies from liver biopsies to immune cells in ascites. To this end 45 patients with cirrhosis and non-infected ascites, distributed according to disease etiology, HCV (n = 15) or alcohol (n = 30) were studied. Cytokines and the cell content in ascites were assessed by ELISA and flow cytometry, respectively. Cytokines and ERK phosphorylation in peritoneal monocyte-derived macrophages isolated and stimulated in vitro were also determined. Results A different pattern of leukocyte migration to the peritoneal cavity and differences in the primed status of macrophages in cirrhosis were observed depending on the viral or alcoholic etiology. Whereas no differences in peripheral blood cell subpopulations could be observed, T lymphocyte, monocyte and polymorphonuclear cell populations in ascites were more abundant in the HCV than the alcohol etiology. HCV-related cirrhosis etiology was associated with a decreased inflammatory profile in ascites compared with the alcoholic etiology. Higher levels of IL-10 and lower levels of IL-6 and IL-12 were observed in ascitic fluid from the HCV group. Isolated peritoneal monocyte-derived macrophages maintained their primed status in vitro throughout the 24 h culture period. The level of ERK1/2 phosphorylation was higher in ALC peritoneal macrophages at baseline than in HCV patients, although the addition of LPS induced a greater increase in ERK1/2 phosphorylation in HCV than in ALC patients.

    Multiple factors in the tumor microenvironment were found to inhibit antitumor adaptive immune responses, allowing tumor persistence and growth. In this study, ascites from ovarian cancer patients were collected. We observed that a population of interleukin-10(+) B (IL-10(+) B) cells was preferentially enriched in the ascites. This population was associated with naive B cell phenotype or IgM or class-switched memory B cell phenotypes. The frequencies of IL-10(+) B cells were negatively correlated with the frequencies of interferon gamma-producing (IFN-g(+)) CD8(+) T cells and were positively correlated with the frequencies of Foxp3(+) CD4(+) T cells. To examine whether increased IL-10(+) B cells in ascites could directly result in increased suppression of IFN-g production by CD8(+) T cells, we cocultured CD8(+) T cells with autologous blood B cells or ascitic B cells and found that CD8(+) T cells cocultured with ascitic B cells demonstrated significantly suppressed IFN-g production. This suppression was in part mediated by IL-10 as well as low CD80/CD86 expression, since depletion of IL-10 and stimulation of CD28 partially reverted IL-10(+) B cell-mediated suppression. Together, these data demonstrated an additional regulatory mechanism in the tumor microenvironment, which utilizes IL-10(+) B cells.

    The current study was to prepare a mouse-derived antibody against the angiotensin II type 1 receptor (AT1-mAb) based on monoclonal antibody technology, to provide a foundation for research on AT1-AA-positive diseases. Balb/C mice were actively immunized with the second extracellular loop of the angiotensin II type 1 receptor (AT1R-ECII). Then, mouse spleen lymphocytes were fused with myeloma cells and monoclonal hybridomas that secreted AT1-mAb were generated and cultured, after which those in logarithmic-phase were injected into the abdominal cavity of mice to retrieve the ascites. Highly purified AT1-mAb was isolated from mouse ascites after injection with 1 × 107 hybridomas. A greater amount of AT1-mAb was purified from mouse ascites compared to the cell supernatant of hybridomas. AT1-mAb purified from mouse ascites constricted the thoracic aorta of mice and increased the beat frequency of neonatal rat myocardial cells via the AT1R, identical to the effects of AT1-AA extracted from patients' sera. Murine blood pressure increased after intravenous injection of AT1-mAb via the tail vein. High purity and good biological activity of AT1-mAb can be obtained from mouse ascites after intraperitoneal injection of monoclonal hybridomas that secrete AT1-mAb. These data provide a simple tool for studying AT1-AA-positive diseases. PMID:27057554

    The aim of this research is to evaluate the recent changes in microorganisms causing spontaneous bacterial peritonitis in cirrhotic patients, antibiotic resistance, and response to empirical cephalosporin therapy. A total of 218 patients with ascites secondary to cirrhosis were enrolled. Parenteral cefotaxime or cefepime was given to patients who had a neutrophil count of 250/mm(3) or more or a positive bacterial culture of ascitic fluid. Antibiotic failure was defined by an absence of clinical improvement and an insufficient decrease in neutrophil count of ascites (<25% of initial value) by the third day of therapy. Of all the patients, 44.6% had culture-negative neutrocytic ascites, 24.8% had spontaneous bacterial peritonitis, and 10.1% had monomicrobial nonneutrocytic bacterascites. Growth in culture was observed in 76 patients (34.9%). The two most common isolated bacteria were Escherichia coli (33.8%) and coagulase-negative Staphylococcus (CoNS; 19.7%). The two cephalosporins were effective against E. coli (82%) and but not against CoNS (44%), while levofloxacin showed reasonable activity against both E. coli (71%) and CoNS (90%) in vitro. We confirmed a recent increased incidence of spontaneous bacterial peritonitis caused by Gram-positive bacteria. Levofloxacin seems to be a good alternative treatment for patients with uncomplicated spontaneous ascites infections.

    2016-01-01

    Background: Diagnosis of spontaneous bacterial peritonitis in cirrhosis can be made when a patient has an ascites polymorphonuclear leukocyte count ≥250/mm3. However, symptomatic bacterascites, which is a variant of spontaneous bacterial peritonitis with signs of infection but an ascites polymorphonuclear leukocyte count <250/mm3, cannot be confirmed until the time-consuming ascites culture becomes positive. Currently, early indicators for symptomatic bacterascites remain undetermined. Aims: To develop a quick screening model for early detection of symptomatic bacterascites in cirrhosis. Materials and Methods: Data on patients with cirrhotic ascites from two hospitals (from 2010 to 2014) were collected retrospectively. Patients with symptomatic bacterascites were enrolled in the case group and compared with patients without any infection in the control group. Logistic regression analysis was used to build a model for screening symptomatic bacterascites, and a receiver operating characteristics curve was used to assess the model. Results: In total, 103 patients were enrolled in the case group and 204 patients were enrolled in the control group. A screening model was constructed based on body temperature, abdominal tenderness, blood neutrophil percentage, blood total bilirubin, prothrombin time, and ascites nucleated leukocyte count. The area under the receiver operating characteristic curve was 0.939; a screening score of 0.328 was the best cutoff value. Conclusion: Patients with suspected symptomatic bacterascites can be quickly screened according to the developed model, and a screening score ≥0.328 indicates symptomatic bacterascites.

    The role of nitric oxide (NO) in graft-versus-tumor-effect (GVT) was evaluated in the present study. GVT was induced by intravenous injection of C57BL/6J (H-2b) mouse splenocytes to {C57BL/6J (H-2b) x BALB/c (H-2d)} F1 mice bearing Meth A (H-2d) ascites tumors. Induction of GVT increased nitrite production and expression of inducible NO synthase by ascites cells. The increased nitrite production was inhibited by NG-monomethyl-L-arginine (MLA). Experiments employing immunomagnetic depletion of Mac-1+ cells from ascites indicated that macrophages were a major cellular source of the nitrite production. Interferon-gamma levels were increased in both serum and ascites fluid during GVT. Induction of GVT prolonged survival of ascites-bearing mice, and increased urinary nitrate excretion. MLA administration inhibited GVT-induced increase in urinary nitrate excretion, and further prolonged GVT-induced increase in survival. These results indicate that NO synthesis is induced in tumors during GVT, and the NO acts as an inhibitor of GVT.

    We describe the case of a 23 year old man who had undergone laparoscopic surgery in order to remove a residual mass secondary to a testicular embryonal carcinoma. 15 days after he attended the emergency department complaining about abdominal bloating and copious drainage via the two laparoscopic surgery incisions. Biochemical analysis was consistent with chylous ascites. Although this is uncommon, it is well known that there is more likely to develop chylous ascites after oncologic surgery if retroperitoneal lymph nodes dissection is performed1. We decide to start with conservative treatment (dietary modifications) but, as it is not enough, then we decide stop any oral intake and treat him with parenteral nutrition, achieving then total resolution of the ascites.

    Background: Peritoneal tuberculosis accounts 1-2% of all forms of tuberculosis. Peritoneal tuberculosis is an important differential diagnosis for ovarian cancer in women with ascites, adnexal mass and elevated cancer antigen 125 (CA125) levels. We report a case of a 32- year -old woman with multiple miliary peritoneal deposits mimicking advanced ovarian carcinoma. Case Presentation: A 32-year-old drug addicted woman presented with menometrorrhagia, fever and shivering, ascites and pelvis mass. Ultrasonography revealed a 53×65 mm cyst in left ovary and ascites. Multiple miliary peritoneal deposits were observed during laparatomy without any mass, histologic examination confirmed tuberculosis of uterus, tubes, omentum, liver and external surfaces of small intestine. Finally, the patient recovered with anti-tuberculosis treatment. Conclusion: These findings highlight considering tuberculosis in the differential diagnosis of any patients with adnexal mass, ascitis and elevated serum CA125 even with negative cytology and bacteriology test results.

    Bacteriophages are viruses that infect bacteria, and they are found everywhere their bacterial hosts are present, including the human body. To explore the presence of phages in clinical samples, we assessed 65 clinical samples (blood, ascitic fluid, urine, cerebrospinal fluid, and serum). Infectious tailed phages were detected in >45% of ascitic fluid and urine samples. Three examples of phage interference with bacterial isolation were observed. Phages prevented the confluent bacterial growth required for an antibiogram assay when the inoculum was taken from an agar plate containing lysis plaques, but not when taken from a single colony in a phage-free area. In addition, bacteria were isolated directly from ascitic fluid, but not after liquid enrichment culture of the same samples, since phage propagation lysed the bacteria. Lastly, Gram-negative bacilli observed in a urine sample did not grow on agar plates due to the high densities of infectious phages in the sample. PMID:27609086

    A 72-year-old man underwent surgery for advanced gastric cancer. Systemic chemotherapy was started, using a regimen of S-1/CDDP for 4 courses, followed by 8 courses of S-1. Three years and 8 months after the surgery, abdominal CT demonstrated ascites, and the serum CA19-9 level was abnormally high (1,165.1 U/mL). Adenocarcinoma cells were found in the ascites. Treatment with S-1/docetaxel (DOC) was started. After 10 courses, the ascites disappeared and the serum CA19-9 value returned to normal. Four years and 7 months after the operation, the patient has been in good health, with no signs of recurrence.

    The production of ascitic fluid and splenomegaly on intraperitoneal injection in weanlings was used as a test for microsporidia after introduction by other routes and in other loci. Oral and cerebral administration was followed only by enlarged spleens which reproduced the ascitic response on passage. Microsporidia were demonstrable by phase microscopy in all fluids. Positive findings were also obtained with liver, kidney, brain, lungs, blood, and urine. Intramuscular and intranasal injection were occasionally followed by ascites, but splenomegaly again predominated. The results of contact experiments indicated that the organisms were not readily communicable either in weanlings or nurslings. Relation of the microsporidian to Encephalitozoon cuniculi (Nosema cuniculi Lainson et al.) is discussed. Images PMID:4862191

    Nine peritoneovenous shunts were positioned by percutaneous technique in seven patients with advanced malignancy causing severe refractory ascites, and in two patients with hepatic cirrhosis (one with hepatocarcinoma). In all patients the shunts were percutaneously placed through the subclavian vein in the angiographic suite under digital fluoroscopic guide. No complications directly related to the procedure occurred. The shunt was successfully positioned in all patients in 60 min average time. No patient showed symptoms related to pulmonary overload or to disseminated intravascular coagulation. All patients had a significant improvement of the objective symptoms related to ascites such as respiratory symptoms, dyspepsia, and functional impairment to evacuation describing an improvement of their quality of life. Maximum shunt patency was 273 days. Percutaneous placement of peritoneovenous shunt is a safe, fast, and inexpensive procedure, extremely useful in resolution of refractory ascites, reducing symptoms, and allowing effective palliation, with a great improvement in quality of life.

    Urachal mucinous cystadenocarcinoma causing pseudomyxoma peritonei is very rare. We report a case of a 59-year-old man with urachal mucinous adenocarcinoma associated with pseudomyxoma peritonei, and our radiologic findings. Ultrasonography revealed a well delineated, large cystic tumor adjacent to the anterior wall of the abdomen. Computed tomography and magnetic resonance imaging revealed a tumor of which the left posterior wall was defective. A large amount of ascites was present in the peritoneal cavity. The ascites caused displacement of the intestinal structures toward the dorsal region. The tumor wall and septa in the ascites were well enhanced on contrast-enhanced images. Radiologically, pseudomyxoma peritonei due to rupture of urachal cystic tumor was considered. The pathologic diagnosis was mucinous adenocarcinoma and pseudomyxoma peritonei.

    A 59-year old man with alcohol related cirrhosis and portal hypertension was referred for transjugular intrahepatic portosystemic shunt (TIPS) to treat his refractory ascites. Ten years later, two sequential TIPS revisions were performed for shunt stenosis and recurrent ascites. After these revisions, he returned with increased serum pancreatic enzyme levels and disseminated superficial fat necrosis; an iatrogenic pancreaticoportal vein fistula caused by disruption of the pancreatic duct was suspected. The bare area of the TIPS was subsequently lined with a covered stent-graft, and serum enzyme levels returned to baseline. In the interval follow-up period, the patient has clinically improved.

    We present two cases of umbilical hernia incarceration following large volume paracentesis (LVP) in patients with cirrhotic ascites. Both patients became symptomatic within 48 hours after the LVP. Although being rare, given the significantly higher mortality rate of cirrhotic patients undergoing emergent herniorrhaphy, this complication of LVP is potentially serious. Therefore, it is recommended that patients be examined closely for the presence of umbilical hernias before removal of ascitic fluid and an attempt should be made for external reduction of easily reducible hernias, if a hernia is present.

    The creation of a transjugular intrahepatic portosystemic shunt (TIPS) is a critical procedure for the treatment of recurrent variceal bleeding and refractory ascites in the setting of portal hypertension. Chronic portal vein thrombosis remains a relative contraindication to conventional TIPS and options are limited in this scenario. Presented is a novel technique for management of refractory ascites in a patient with hepatitis C cirrhosis and chronic portal and superior mesenteric vein thrombosis secondary to schistosomiasis and lupus anticoagulant utilizing fluoroscopically guided percutaneous mesocaval shunt creation.

    From two cases of pseudomyxoma peritonei of ovarian origin, the authors review the subject and emphasize the rarity of this condition. The diagnosis is simple once the decision to operate is made. Treatment, however, is disappointing because of recurrences. The pathogenesis is not well understood, and further studies are warranted of this condition by histochemists and physiologists to better understand the secreting mechanisms causing the ascites and methods to control it. Mortality is principally related to mechanical complications due to ascites and the characteristics of the groups of secretory cells.

    Peritoneal vasculitis is a rare and severe clinical manifestation of systemic lupus erythematosus. We report a patient who presented with ascites due to peritoneal vasculitis and cutaneous, articular, hematological and renal inflammatory activity. Treatment with glucocorticoids and immunosuppressive drugs was ineffective. In view of the resistance to different therapies, 4 weekly infusions of 375mg/m2 of rituximab (RTX) were started, in association with cyclophosphamide pulses during the first and the third weeks. With this treatment strategy, the patient reached a complete response which was achieved in later flares of inflammatory activity (the second and third flares were multisystemic and with ascites again, and the fourth flare with nephritis).

    2016-11-01

    Ascites can cause pleural effusions when the peritoneal fluid crosses the diaphragm through a pleuroperitoneal shunt in the setting of hepatic cirrhosis (hepatic hydrothorax) or malignant ascites. Scintigraphic imaging for pleuroperitoneal shunt requires intraperitoneal injection of Tc-SC or Tc-macroaggregated albumin followed by planar imaging of the chest and abdomen. Pleuroperitoneal shunt is confirmed by identifying radiotracer crossing the diaphragm from the peritoneal to pleural space. An atlas of pleuroperitoneal shunt imaging pitfalls is presented to facilitate optimal performance and interpretation of nuclear pleuroperitoneal shunt examinations. Examples include cases of nondiagnostic radiotracer injections, processing errors, and nontarget uptake.

    Acute umbilical hernia rupture in patients with hepatic cirrhosis and ascites is an unusual, but potentially life-threatening complication, with postoperative morbidity about 70% and mortality between 60%-80% after supportive care and 6%-20% after urgent surgical repair. Management options include primary surgical repair with or without concomitant portal venous system decompression for the control of the ascites. We present a retrospective analysis of our centre’s experience over the last 6 years. Our cohort consisted of 11 consecutive patients (median age: 53 years, range: 36-63 years) with advanced hepatic cirrhosis and refractory ascites. Appropriate patient resuscitation and optimisation with intravenous fluids, prophylactic antibiotics and local measures was instituted. One failed attempt for conservative management was followed by a successful primary repair. In all cases, with one exception, a primary repair with non-absorbable Nylon, interrupted sutures, without mesh, was performed. The perioperative complication rate was 25% and the recurrence rate 8.3%. No mortality was recorded. Median length of hospital stay was 14 d (range: 4-31 d). Based on our experience, the management of ruptured umbilical hernias in patients with advanced hepatic cirrhosis and refractory ascites is feasible without the use of transjugular intrahepatic portosystemic shunt routinely in the preoperative period, provided that meticulous patient optimisation is performed.

    Background Peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) is a rare neoplasm that typically presents as generalized lymphadenopathy. PTCL, NOS presenting as malignant ascites is rare. Methods A 61-year-old African-American man with past medical history of HCV, cryoglobulinemia, and cryptococcal pneumonia was admitted for dyspnea on exertion over a period of 1 month and new onset of abdominal distension. Results Ascites, splenomegaly, hepatomegaly and extensive lymphadenopathy were found by imaging. Paracentesis obtained 1.3 liter of abdominal fluid, the cytologic evaluation showed a monomorphic population of intermediate-sized lymphoid cells with irregular to convoluted nuclear contours. Fluid sent for flow cytometry showed an abnormal T-lymphocyte population expressing CD4, weak surface CD3 and absence of CD7. PCR studies of ascitic fluid detected a clonal T-lymphocyte population with T-cell receptor gamma gene rearrangement. Serologic testing for human T lymphotropic virus (HTLV) was positive for HTLV-II. Subsequent bone marrow biopsy revealed lymphomatous involvement. CD30 and ALK-1 immunostaining were negative. This case was classified as PTCL, NOS. Conclusions PTCL, NOS can have unusual clinical presentation such as ascites and pleural effusion, and may also occur as a complication of immunodeficiency state. Further studies are needed to determine if HCV or HTLV-II viral infection is associated with PTCL. PMID:27034820

    Transforming growth factor beta (TGFβ) is a family of genes that play a key role in mediating tissue remodeling in various forms of acute and chronic lung disease. In order to assess their role on pulmonary hypertension in broilers, we determined mRNA expression of genes of the TGFβ family and endothelin 1 in lung samples from 4-week-old chickens raised either under normal or cold temperature conditions. Both in control and cold-treated groups of broilers, endothelin 1 mRNA expression levels in lungs from ascitic chickens were higher than levels from healthy birds (P < 0.05), whereas levels in animals with cardiac failure were intermediate. Conversely, TGFβ2 and TGFβ3 gene expression in lungs were higher in healthy animals than in ascitic animals in both groups (P < 0.05). TGFβ1, TβRI, and TβRII mRNA gene expression among healthy, ascitic, and chickens with cardiac failure showed no differences (P > 0.05). BAMBI mRNA gene expression was lowest in birds with ascites only in the control group as compared with the values from healthy birds (P < 0.05). PMID:24286074

    After prenatal diagnosis of bilateral fetal hydrothorax, ascites, and polyhydramnios, bilateral thoracoamniotic shunts were placed at 29 weeks gestation using an ultrasound-guided, minimally invasive technique. Anesthetic care was managed using intravenous sedation and local anesthesia infiltration. The anesthetic considerations for such procedures are discussed.

  10. Portal hypertension.

    Portal hypertension is the main complication of cirrhosis and is responsible for its most common complications: variceal hemorrhage, ascites, and portosystemic encephalopathy. Portal hypertension is the result of increased intrahepatic resistance and increased portal venous inflow. Vasodilatation (splanchnic and systemic) and the hyperdynamic circulation are hemodynamic abnormalities typical of cirrhosis and portal hypertension. Gastroesophageal varices result almost solely from portal hypertension, although the hyperdynamic circulation contributes to variceal growth and hemorrhage. Ascites results from sinusoidal hypertension and sodium retention, which is in turn secondary to vasodilatation and activation of neurohumoral systems. Hepatic hydrothorax results from the passage of ascites across the diaphragm and into the pleural space. The hepatorenal syndrome represents the result of extreme vasodilatation with an extreme decrease in effective blood volume that leads to maximal activation of vasoconstrictive systems, renal vasoconstriction, and renal failure. Spontaneous bacterial peritonitis is a potentially lethal infection of ascites that occurs in the absence of a local source of infection. Portosystemic encephalopathy is a consequence of both portal hypertension (shunting of blood through portosystemic collaterals) and hepatic insufficiency resulting in the accumulation of neurotoxins in the brain.

    Transforming growth factor beta (TGF β ) is a family of genes that play a key role in mediating tissue remodeling in various forms of acute and chronic lung disease. In order to assess their role on pulmonary hypertension in broilers, we determined mRNA expression of genes of the TGF β family and endothelin 1 in lung samples from 4-week-old chickens raised either under normal or cold temperature conditions. Both in control and cold-treated groups of broilers, endothelin 1 mRNA expression levels in lungs from ascitic chickens were higher than levels from healthy birds (P < 0.05), whereas levels in animals with cardiac failure were intermediate. Conversely, TGF β 2 and TGF β 3 gene expression in lungs were higher in healthy animals than in ascitic animals in both groups (P < 0.05). TGF β 1, T β RI, and T β RII mRNA gene expression among healthy, ascitic, and chickens with cardiac failure showed no differences (P > 0.05). BAMBI mRNA gene expression was lowest in birds with ascites only in the control group as compared with the values from healthy birds (P < 0.05).

    The first results about the anti-neoplastic activity of Pd(II) ion coordinative compounds with complexones of the ethylenediamine-tetraacetic acid type are described. The assays employing Ehrlich ascites cancer of the mouse show that the presence of substitutes in the ethylenediamine skeleton originates important changes of the activity of such compounds.
