    The most common complication to chronic liver failure is ascites. The formation of ascites in the cirrhotic patient is caused by a complex chain of pathophysiological events involving portal hypertension and progressive vascular dysfunction. Since ascites formation represents a hallmark in the natural history of chronic liver failure it predicts a poor outcome with a 50% mortality rate within 3 years. Patients with ascites are at high risk of developing complications such as spontaneous bacterial peritonitis, hyponatremia and progressive renal impairment. Adequate management of cirrhotic ascites and its complications betters quality of life and increases survival. This paper summarizes the pathophysiology behind cirrhotic ascites and the diagnostic approaches, as well as outlining the current treatment options. Despite improved medical treatment of ascites, liver transplantation remains the ultimate treatment and early referral of the patient to a highly specialized hepatology unit should always be considered.

    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.

    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.

    Ascites is the most common complication of cirrhosis. Ascites develops as a consequence of an abnormal splanchnic vasodilation with reduction of effecting circulating volume and activation of endogenous vasoconstrictors system causing salt and water retention. Patients with ascites have a high risk to develop further complications of cirrhosis such as hyponatremia, spontaneous bacterial peritonitis and acute kidney injury resulting in a poor survival. In recent years, new studies helped a better understanding of the pathophysiology of ascites and acute kidney injury in cirrhosis. Furthermore, new diagnostic criteria have been proposed for acute kidney injury and hepatorenal syndrome and a new algorithm for their management has been recommended with the aim of an early diagnosis and treatment. Herein we will review the current knowledge on the pathophysiology, diagnosis and treatment of ascites and acute kidney injury in patients with cirrhosis and we will identify the unmet needs that should be clarified in the next years.

    Two patients with sonographically documented fetal ascites are described. Workup for immunologic or nonimmunologic causes was negative. Subsequent sonar examinations demonstrated disappearance of fetal ascites. At delivery, previous abdominal distention was apparent. Fetal ascites of unknown etiology in the late second trimester does not necessarily have a poor prognosis. Serial sonographic examinations are indicated for follow-up of fetal ascites.

    Eosinophilic ascites is a rare feature of eosinophilic gastroenteritis. We would like to highlight this increasingly recognised diagnosis in a case of unexplained ascites. We present a challenging case of a woman aged 25 years who presented with nausea, vomiting, diarrhoea, generalised abdominal pain and swelling 8-week following delivery of her first baby. Her symptoms were primarily aggravated by eating, and she had also noticed postprandial itching and self-limiting generalised rash. She had a strong history of atopy. Physical examination revealed abdominal tenderness and distension with shifting dullness. Urticarial skin rash was noted on the face, neck, chest and abdomen. Routine biochemistry was normal apart from peripheral eosinophilia. Imaging confirmed moderate ascites. Diagnostic paracentesis showed exudative ascites with numerous eosinophils. Histology of the upper and lower gastrointestinal tract showed infiltration of the oesophageogastroduodenal and rectosigmoid mucosa with eosinophils. The patient significantly improved following a course of steroids and six-food elimination diet. PMID:27600059

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

    2014-01-01

    Ascites is the pathologic accumulation of fluid within the peritoneal cavity. Because many diseases can cause ascites, in particular cirrhosis, samples of ascitic fluid are commonly analyzed in order to develop a differential diagnosis. The concept of transudate versus exudate, as determined by total protein measurements, is outdated and the use of serum-ascites albumin gradient as an indicator of portal hypertension is more accurate. Lactate dehydrogenase (LDH), vascular endothelial growth factor (VEGF), and other tumor markers can be helpful in distinguishing between malignant and benign conditions. Glucose and adenosine deaminase levels may support a diagnosis of tuberculous disease, and amylase level may indicate a diagnosis of pancreatitis. Given the specificity and sensitivity of laboratory results, accurate diagnosis should be based on both laboratory data and clinical judgment. PMID:26357618

    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

    2014-01-01

    Chylous ascites refers to the accumulation of lipid-rich lymph in the peritoneal cavity due to disruption of the lymphatic system secondary to traumatic injury or obstruction. Worldwide, abdominal malignancy, cirrhosis, and tuberculosis are the commonest causes of CA in adults, the latter being most prevalent in developing countries, whereas congenital abnormalities of the lymphatic system and trauma are commonest in children. The presence of a milky, creamy appearing ascitic fluid with triglyceride content above 200 mg/dL is diagnostic, and, in the majority of cases, unless there is a strong suspicion of malignancy, further investigations are not required in patients with cirrhosis. If an underlying cause is identified, targeted therapy is possible, but most cases will be treated conservatively, with dietary support including high-protein and low-fat diets supplemented with medium-chain triglycerides, therapeutic paracentesis, total parenteral nutrition, and somatostatins. Rarely, resistant cases have been treated by transjugular intrahepatic portosystemic shunt, surgical exploration, or peritoneovenous shunt. PMID:27335837

  14. New proposal for the serum ascites albumin gradient cut-off value in Chinese ascitic patients

    2013-01-01

    Background Serum ascites albumin gradient (SAAG) has been recognized as a reliable marker in the differential diagnosis of ascites. The etiological background of cirrhosis is rather different between western countries and eastern countries. The threshold of SAAG in Chinese ascitic patients has not been evaluated yet. The aim of this study was to define a new reasonable threshold of SAAG in Chinese ascitic patients. Methods Adult patients with ascites admitted to the Shanghai Changzheng Hospital from Jan 2004 to Jun 2010 were retrospectively analyzed. The diagnostic criteria for cirrhotic ascites are clinical manifestations, radiological features and esophageal-gastric varicosis, or histopathology. Serum was detected by chemical method using a commercial kit. We used receiver operating characteristic (ROC) analysis to achieve maximal sensitivity and specificity of SAAG. Results The mean value of SAAG in portal-hypertension-related ascites was significantly higher than that in the non-portal-hypertension-related ascites (21.15 ± 4.38 g/L vs 7.48 ± 3.64 g/L, P = 0.002). The SAAG cut-off value under 12.50 g/L predicted portal hypertension ascites with the sensitivity of 99.20%, specificity of 95.10% and accuracy of 97.65%. Conclusions SAAG is useful to distinguish portal-hypertension-related ascites and non-portal-hypertension-related ascites, and 12.50 g/L might present as a more reasonable threshold in Chinese ascitic patients.

    Pancreatic ascites is an entity defined as amylase levels up to 1.000 U/l in ascitic liquid. Frequently, it is secondary to a rupture of pancreatic ductus or pseudocyst and foreward communication to peritoneal space. We present a male diagnosed of calcified alcoholic chronic pancreatitis with pancreatic ascites secondary to a pseudocyst. Combination of parenteral nutrition and sintetic cyclic somatostatin was efficient. It would act by reducing pancreatic secretion in a long-term manner, which is the final purpose of the treatment. This association would be considered as a former tool in ascitic pancreatic patients, evacuatory punction or delayed surgery been relegated to a conservatory treatment failure or when primary pathology indicate it.

    Chylous ascites is an uncommon form of ascites characterized by milky-appearing fluid caused by blocked or disrupted lymph flow through chyle-transporting vessels. The most common causes of chylous ascites are therapeutic interventions and trauma. In this report, we present four cases of chylous ascites following robot-assisted surgery for endometrial staging and the treatment strategies that we used. After retroperitoneal lymph node dissection, leaving a drain is very useful in diagnosing chylous ascites and observing its resolution; furthermore, the use of octreotide in conjunction with TPN appears to be an efficient treatment modality for chylous ascites and should be considered before any invasive intervention.

    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

    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

    A series of 45 patients with chylous ascites has been reviewed. The age at presentation ranged from 1 to 80 (median 12) years; 23 patients were aged < or = 15 years. Thirty-five patients had an abnormality of the lymphatics (primary chylous ascites); in the remaining ten, the ascites was secondary to other conditions, principally non-Hodgkin's lymphoma (six patients). Two principal mechanisms of ascites formation were identified using lymphangiography and inspection at laparotomy: leakage from retroperitoneal megalymphatics, usually through a visible lymphoperitoneal fistula (14 patients); and leakage from dilated subserosal lymphatics of the small intestine, invariably associated with leaking lacteals causing protein-losing enteropathy (24 patients). Both sites of leakage were present in a further five patients. In the remaining two patients, chyle was leaking from normal mesenteric lymphatics, in one via a ruptured mesenteric lymph cyst and in the other from the site of a previous lymph node biopsy. Other associated lymphatic abnormalities were present in 36 patients, lymphoedema of the leg being the commonest (26 patients). All patients were initially treated conservatively with dietary manipulation; this was the most satisfactory treatment for those with leaking small bowel lymphatics. Surgery (fistula closure, bowel resection or insertion of a peritoneovenous shunt) was performed in 30 patients. Closure of a retroperitoneal fistula, when present, was the most successful operation, curing seven of the 12 patients so treated.

    Novel cell-free and concentrated ascites reinfusion therapy (KM-CART) is easy to use, safe and applicable for refractory ascites. We can get the full amount of ascites, filtrate, and concentrate in a short time. KM-CART can be applied as palliative care for dying patients including patients with massive malignant ascites. Some patients who underwent repeated KM-CART survived longer than those who did not repeat the therapy. The aim of this study was to identify the type of patients with ascites for whom KM-CART would be effective and candidates for repeated KM-CART. In this retrospective cohort observational study, we examined 123 CART processes performed on 58 patients with refractory ascites. Data were collected before and after processing of the ascites. We compared two groups; patients who underwent KM-CART ≥ 5 times and those who underwent this process ≤ 4 times. Age, disease, benign or malignant status of the disease, the amount of ascites, concentrations of total protein (TP) and albumin (Alb) and their amounts in the original ascites and the filtered and concentrated ascitic fluid and the recovery ratio of TP and Alb were determined. No significant difference was observed between the two groups in age, disease, amount of ascites, and the recovery ratio of TP and Alb. Significant differences were observed in the amounts of TP and Alb in the original ascites and the filtered and concentrated ascitic fluid. Patients who underwent KM-CART ≥ 5 times had higher Alb levels in the original ascites than those who underwent this therapy ≤ 4 times. Patients with higher Alb concentrations in the original ascites could be candidates for repeated KM-CART. PMID:26386222

    Live donor renal transplantation offers many significant advantages over cadaveric donor transplantation. Yet living donation continues to be underused, accounting for less than 30% of all donor renal transplants. In an attempt to remove the disincentives to live donation, Ratner et al. developed laparoscopic donor nephrectomy (LDN). LDN is gaining acceptance in the transplant community. The overriding concern must always be the safety and welfare of the donor. To this end, potential complications of LDN must be identified and discussed. We present a patient who developed the complication of chylous ascites from LDN. To improve the laparoscopic technique further, a discussion of its successes and complications needs to be encouraged. To this end, we present chylous ascites as a potential complication after LDN. We also offer suggestions to minimize the likelihood of this complication. PMID:12137847

Analysis of ascites revealed high levels of AFP and CA 125. Laparoscopic biopsy showed endodermal sinus tumour. He was treated with four courses of the BEP regimen (bleomycin, etoposide, cisplatin). The patient was died 2 months after the first appearance of the ascites. Endodermal sinus tumor (EST) is a rare neoplasm which usually arises in the testis or ovary. But extragonadal EST especially located in the abdomen is very rare condition. Clinicians should remain vigilant particularly, when there is a low gradient ascites and are high levels of tumor markers in ascites in young patients.

    Male broilers of two genetically related stocks with divergent growth rates and feed conversion ratios were used to study metabolic backgrounds on the occurrence of pulmonary hypertension, heart failure, hypoxemia, and ascites in poultry. An experiment with a 2 x 2 x 2 x 2 factorial split-plot arrangement of treatments with 96 groups of 12 broilers was performed. Effects of stock and environmental factors such as ambient temperature, dietary fat, and dietary energy on performance, energy metabolism, oxygen consumption, hematocrit values, and mortality were investigated in broilers from 1 to 5 wk of age. Dissimilar responses of the two stocks to environmental factors reflected genotype by environment interactions and revealed metabolic disorders related to heart failure and ascites. The results indicated that in the stock with the lower feed conversion ratio, a fast protein accretion was achieved together with a reduced ability to convert chemical energy to metabolic heat and to deposit body fat directly from ingested fat. Birds with a low feed conversion ratio show less flexibility in metabolic adaptation to a changing environment, which can account for the development of ascites. PMID:1852684

    We describe a case of a 43-year-old man presenting to the gastroenterology outpatient department with exudative ascites. Mediastinal lymphadenopathy, pericardial effusion and pleural effusion were detected on further imaging. Further clinical examination revealed subcutaneous nodules on the left arm, which were confirmed to be rheumatoid nodules on histology. Inflammatory markers were elevated with positive serology for rheumatoid factor and anticyclic citrullinated protein antibody. Our investigations excluded tuberculosis, pancreatitis and malignancy in the patient. Following review by a rheumatologist, a diagnosis of systemic rheumatoid arthritis (RA) was made. Pleuritis and pericarditis are well recognised as extra-articular manifestation of RA. Ascites, however, is rarely recognised as a manifestation of RA. Our literature search revealed two other cases of ascites due to RA disease activity, and both patients had long-standing known RA. This case adds to the discussion on whether ascites and peritonitis should be classified as extra-articular manifestations of RA.

    Ascites with the finding of peritoneal carcinomatosis is considered an unusual presentation for mantle cell lymphoma (MCL) and has been rarely described in literature. This case reflects the importance of cytological analysis of peritoneal fluid in a patient with intractable ascites not contributing from other comorbidities. In the event a bone marrow (BM) analysis cannot be made, this may serve as an alternative method for diagnosing MCL taking into consideration the good concordance between peritoneal fluid and BM cytological markers.

    Spontaneous bacterial peritonitis in patients with chronic hepatitis represents a very controversial matter in terms of frequency, pathology and treatment. This unusual complication mainly due to decreased immunological defences and ascitic fluid opsonic activity is not accepted by all the Authors as a rare event. However, there is agreement as far as management is concerned: cultural examination of the ascitic fluid and the relative antibiogram are the best tools in guiding the approach to an adequate antibiotic therapy.

    AIM: To determine the effects of total parenteral nutrition and somatostatin on patients with chylous ascites. METHODS: Five patients were diagnosed with chylous ascites on the basis of laboratory findings of ascites sample from Nov 1999 to May 2003. Total parenteral nutrition and somatostatin or its analogue was administered to 4 patients, while the other one only received total parenteral nutrition. All the patients had persistent peritoneal drainage, with the quantity and quality of drainage fluid observed daily. Necessary supportive treatments were given to the patients individually during the therapy. RESULTS: Two of 4 patients who received somatostatin therapy obtained complete recovery within 10 d without any recurrence while on a normal diet. In these 2 patients, the peritoneal drainage reduced to zero in one and the other's decreased from 2000 mL to 80 mL with a clear appearance and negative qualitative analysis of chyle. Recurrent chylous ascites, though relieved effectively by the same method every time, developed in one patient with advanced pancreatic cancer. The other patient's lymphatic fistula was blocked with the fibrin glue after conservative treatment. The patient who only received total parenteral nutrition was cured 24 d after therapy. CONCLUSION: Total parenteral nutrition along with somatostatin can relieve the symptoms and close the fistula in patients with chylous ascites rapidly. It appears to be an effective therapy available for the treatment of chylous ascites caused by various disorders. PMID:15300913

    Ascites and renal dysfunction are frequent complications experienced by patients with cirrhosis of the liver. Ascites is the pathologic accumulation of fluid in the peritoneal cavity, and is one of the cardinal signs of portal hypertension. The diagnostic evaluation of ascites involves assessment of its granulocyte count and protein concentration to exclude complications such as infection or malignoma and to allow risk stratification for the development of spontaneous peritonitis. Although sodium restriction and diuretics remain the cornerstone of the management of ascites, many patients require additional therapy when they become refractory to this treatment. In this situation, the treatment of choice is repeated large-volume paracentesis. Alteration in splanchnic hemodynamics is one of the most important changes underlying the development of ascites. Further splanchnic dilation leads to changes in systemic hemodynamics, activating vasopressor agents and leading to decreased renal perfusion. Small alterations in renal function influence the prognosis, which depends on the cause of renal failure. Prerenal failure is evident in about 70% of patients, whereas in about 30% of patients the cause is hepatorenal syndrome (HRS), which is associated with a worse prognosis. Therefore, effective therapy is of great clinical importance. Recent data indicate that use of the new definition of acute kidney injury facilitates the identification and treatment of patients with renal insufficiency more rapidly than use of the current criteria for HRS. In this review article, we evaluate approaches to the management of patients with ascites and HRS. PMID:25729433

    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

    A 46-year-old man underwent living-donor liver transplantation and splenectomy for primary biliary cirrhosis. On postoperative day 22, cloudiness of ascites increased, and triglyceride concentration in ascites was as high as 1046 mg/dL. 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

    An 81-year old woman with a history of chronic lymphocytic leukemia (CLL) was admitted with night sweats and abdominal distension. A complete blood count showed hemoglobin 5 g/dL, white blood cell (WBC) count 28.5×109/L and platelets 38.4×109/L. Peripheral blood smear examination showed a large number of smudge cells and lymphocytosis composed of mature-looking lymphocytes with clumped nuclear chromatin. Computed tomography scan demonstrated enlarged cervical, axillary, paraaortic, retroperitoneal and mesenteric lymph nodes with concomitant omental thickening and ascites. Also, the liver and the spleen were enlarged in the presence of multiple ill-defined hypoechoic areas in the latter. Histopathological analysis of the cervical lymph node biopsy was consistent with CLL. Bone marrow examination showed diffuse infiltration of the marrow with small lymphocytes. Analysis of the ascitic fluid revealed an exudate with WBC 1220 cells/mL. Cytocentrifuge preparation of the ascitic fluid showed small mature lymphoid cells containing hyperchromatic nuclei with coarsely granular chromatin. On flow cytometric analysis of the ascitic fluid, expression of CD5, CD19, CD20, CD22, CD23, CD45 and HLA-DR was compatible with a diagnosis of CLL, in accordance with the results of the peripheral blood analysis. The patient was treated with chemotherapy consisting of cyclophosphamide, vincristine and prednisolone but died within one month after development of non-chylous ascites. PMID:23372915

    The conditions of the formation of ascitic cells in BALB/c mice injected with hybridoma cells were studied. All the hybridomas under study, producing monoclonal antibodies to viral antigens, induced the formation of ascitic tumors when introduced into the abdominal cavity of BALB/c mice pretreated with sensitizing agents. In the mice pretreated with pristane hybridoma cells took at a rate of 43-80% and in the mice pretreated with Freund's complete adjuvant, 31-70%. Angara oil and perfume oil, as well as Bayol F, were less effective. The time of the formation of ascites was inversely proportional to the dose of the injected cells, while the volume of ascitic fluid depended rather on the type of hybridoma and not on the dose of the injected cells. The study showed that the use of physiological saline or culture medium without serum for washing the abdominal cavity of mice after withdrawing ascites permitted the additional collection of 2.6-13.7 million hybrid cells, as well as a considerable amount of immunoglobulins.

  1. Ascites-induced LeVeen shunt coagulopathy.

    Ten of 11 patients undergoing peritoneovenous (LeVeen) shunt placement for intractable ascites had disseminated intravascular coagulation (DIC) following the shunt procedure. Intraoperative ascitic fluid specimens revealed fibrin split products (FSP) in high titer (1:100-1:1600) in all patients. Endotoxin was found in 6 of 11 ascitic fluid samples but in no plasma samples. Activated clotting factors, clot inhibitors, excess protein, and fibrinolytic activity were not found in ascitic fluid. Clotting factor levels were much lower than in plasma. Bleeding occurred after operation in two patients; this appeared to be related to the severity of liver dysfunction as demonstrated by elevations of bilirubin, serum glutamic oxalocetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), and preoperative DIC. It is concluded that the LeVeen shunt coagulopathy is DIC, and may be related to exposure of the systemic circulation to FSP-rich ascitic fluid that may activate the coagulation mechanism. Bleeding complications do not appear to be related to the severity of the post shunt coagulopathy, but rather to the severity of liver dysfunction and presence of preoperative DIC (probably caused by the liver disease).

    Chromosomal instability (CI) plays a major role in the carcinogenesis. Micronuclei, nuclear budding, chromatin bridges,and multipolar mitoses are the morphological markers of CI and have never been studied in routine cytological specimens. Aims of the study is to analyze the significance of morphological markers of CI in malignant and benign ascitic fluid smears. A total of sixty benign and 40 malignant ascitic fluid samples were selected for this study. All the cases with malignant ascitic fluid showed histopathological evidence of malignancy in ovary and omentum. Chromatin bridges, multipolar mitosis (MPM), micronuclei and nuclear budding were counted in 1000 cells in representative May Grunwald Giemsa (MGG) stained smears. The CI markers were correlated with the cytological diagnosis of effusion. The mean number of micronuclei, nuclear budding, chromatin bridge and multipolar mitoses found in malignant effusions were 13.2611.79, 10.1067.07, 2.5362.67, 1.964.5, respectively. The mean number of micronuclei, nuclear budding, anaphase bridges, and MPM found in benign effusion cases were 0.566761.07934, 0.516761.33, 0.66760.25, and 0, respectively. The student t test showed significant differences between malignant and benign ascitic fluid samples for each marker of CI. This is the first comprehensive study of morphological markers of CI in ascitic fluid smears. This study has shown strong correlation between markers of CI and cytological diagnosis of malignancy. In future, the knowledge of these markers can be applied to diagnose malignancy in suspected cases of effusion in difficult situations.

    Cell respiration (CR) and glycolysis (GL) are the main sources cell energy, since along their metabolic pathways ATP is produced. Expressed as microM/100 mg/h, normal cells produce 63 by CR, 0.2 by aerobic GL, and 9.37 by anaerobic GL, while cancer cells produce 35 by CR, 18 by aerobic GL, and 29 by anaerobic GL. The ascites fluid from EAC increases the anaerobic GL to 38, while it does not change the aerobic GL to 7 and diminishes the CR to 26. Insulin produces a lowering of CR to 26, aerobic GL to 26 and anaerobic GL to 22. Glucose inhibits CR and stimulates GL. Ribose does not modify CR and inhibits GL. Mannose inhibits both CR and GL. Ribonuclease increases GL in the presence of glucose but not of ribose. Glucose-phosphate and ribose-phosphate have no action because they do not enter into the cell. Expressed as QLN2/100 mg, the main localization of GL is the cytosol (480), but it is significant in the nucleus (170), and diminishes in microsomes (100) and mitochondria (52). Mitochondria inhibit the cytosol glycolytic activity when they are either in the usual proportion they have in the cell or in a higher proportion. It is curious the observation that a diminution of the relative concentration of mitochondria with regard to cytosol (1/100 to 1/1000) produces a marked increase of GL. The addition of nuclear fraction stabilizes the cytosol-mitochondria complex and modifies the metabolic pathway of the CO2 that is produced during the GL.

    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 63-year-old woman, who had undergone radical hysterectomy and radiation therapy for cervical cancer of the uterus three years previously, was found to have pleural effusion and ascites. A diagnosis of chylothorax and chylous ascites was made on the basis of these fluids' characteristics. She received medium-chain triglyceride (MCT) in her diet and intra-venous hyperalimentation to decrease the leakages of chyle into the pleural and peritoneal cavities, but she died of respiratory and renal failures after six months. At autopsy, metastases from the cervical cancer of the uterus to the lymph nodes in the mediastinum and around the abdominal aorta were proved histologically. Lymph node swelling due to metastasis had caused a rupture of the thoracic duct, leading to chylothorax and chylous ascites. The diagnosis, evaluation and therapeutic modalities of the condition are outlined and the literature reviewed.

    Chylous ascites consists of the accumulation of chyle in the peritoneal cavity. Diagnosis is established by cytochemical analysis of the fluid revealing fat globules and high triglyceride content. The majority of cases are caused by pathology that interferes with abdominal retroperitoneal lymphatic drainage. We present two cases of postoperative chylous ascites, one following a bilateral nephrectomy, the other following orthotopic heart transplantation. Treatment is typically conservative with the aim to alleviate abdominal distension and reduce the flow of lymph into the mesenteric lymph nodes. Postsurgical chylous ascites has high cure rate with conservative therapy alone. Therapeutic paracentesis, diuretics, salt restriction, a high-protein, low-fat, mediumchain triglyceride diet, and parenteral nutrition are considered in chronic cases. The effects of longterm paracentesis on patients remains to be seen. In patients requiring renal replacement therapy, removal of chyle during peritoneal dialysis is often attempted.

    1. Male chickens of 7 genetic lines, consisting of two pure sire and two pure dam populations, a commercial broiler cross and two slow-growing chicken lines (Label Rouge, LR and Mechelse Koekoek, MK) were reared from 1 to 37 d of age. The chickens received a two-phase dietary regime and were subjected to low ambient temperature. 2. The experimental aim was to investigate relationships between susceptibility to ascites and heat production. 3. Body weight gain (BWG), food intake and food conversion ratio (FCR) were determined. Ascites mortality, arterial pressure index (API=right ventricular/total ventricular weight ratio), haematocrit values, proportional lung weight (lung weight/body weight x 100), plasma thyroid hormones (thyroxine, T4 and triiodothyronine, T3) and arterial blood gas pressures (pCO2 and pO2) were determined. The heat production per kg metabolic body weight (H/W0.75) and total heat production (H) were calculated for the period 16 to 33 d using an energy balance study according to the comparative slaughter method. 4. The two breeder sire lines had high BWG and low FCR and high but different incidences of ascites compared with the slow-growing ascites resistant LR and MK lines with notable high FCR. The broiler cross and slower-growing breeder dam lines had a similar and relatively lower incidence of ascites mortality. 5. The fast-growing chickens had low H/W0.75 values compared with slow-growing lines. 6. These fast-growing breeder sires had lower plasma thyroid hormone, reduced proportional lung weights, low arterial pO2 and high arterial pCO2 pressures compared with the slower-growing lines. 7. In conclusion, ascites incidence was associated with lower heat production per metabolic body weight and therefore a lower oxygen requirement per metabolic weight. PMID:12828217

    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

    Background: Congenital chylous ascites is a rare condition that constitutes a challenge for the physician. It is defined as the accumulation of chyle into the peritoneal cavity in infants younger than 3 months. This condition is often refractory to therapy and it is responsible for serious malnutrition and immunological deficiency because of the loss of proteins and lymphocytes. Material and methods: Four cases of congenital neonatal chylous ascites, were treated by our staff during the last two years. One case was treated conservatively and three with laparotomy. Two of them had intraabdominal cysts that were excised and one was treated with ligation of the left lumbar lymphatic trunk and cisterna chyli and the use of fibrin glue. Results: All four cases were treated successfully. On follow up tests no one showed recurrence of the ascites. All children, except the one that treated conservatively and also had other problems due to prematurity, are growing up normally. Conclusions: Congenital chylous ascites is a complex condition. Its diagnostic evaluation is difficult and its therapy of long duration. Conservative treatment is in most cases the initial choice, but when it fails, exploratory laparotomy could provide a successful alternative. PMID:23935276

    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

    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

    We treated a 77-year-old woman with pleural and pericardial effusion and ascites. Initially, collagen vascular disease was suspected due to the presence of anti-centromere antibodies and suspected complication of pulmonary arterial hypertension. However, soft-tissue abnormalities surrounding the bilateral kidneys detected on computed tomography (CT) and symmetrical lesions of the long bones detected on bone scintigraphy made us consider a diagnosis of Erdheim-Chester disease (ECD), which is a rare form of histiocytosis. We immunochemically analyzed the cells derived from the ascites in detail and confirmed the diagnosis. Immunocytochemical analyses may therefore help to achieve a better understanding of the pathogenesis of this rare disease. PMID:23037484

    Background In the cases of ascitis, it is essential to determine their origin using the parameters obtained by the cytological and biochemical examinations. The aim of this study was to evaluate the usefulness of different biochemical markers and the number of cells in the differential diagnosis of ascitic fluid (AF). Methods One hundred ninety-one cases of AF were studied, who were admitted to the hospital from January 01, 2009 to December 31, 2014. One hundred fifty-two of them were included in the analysis, and the remaining 39 were excluded because they had more than one associated pathology, clotted or hemolyzed. Results The more frequent etiologies of AF were the cirrhosis (29%), the infections (22%) and the neoplasies (19%). Other pathologies reached 16%. Cutoff > 300 cells/mm3 detected the 78% of exudates. The AF/serum (S) of aspartate aminotransferase (AST) (> 0.5), lactate dehydrogenase (LDH) (> 0.6), proteins (PT) (> 0.5), cholesterol (COL) (> 0.4), and alanine aminotransferase (ALT) (> 0.5) correctly detected 80%, 78%, 72%, 70% and 70% of the exudates, respectively. Conclusion We proposed the utilization of a new cutoff of cellular counting, major of 300/mm3, since it would allow improving the detection of exudate ascites, without including the transudate ascites. AST AF/serum ratio (AF/S) showed the major usefulness in the differentiation and characterization of AF; LDH, proteins, cholesterol and ALT might be also acceptable in the above mentioned differentiation. The serum-ascites albumin gradient (SAAG) turned out to be a good marker of portal hypertension associated with cirrhotic processes. Creatine kinase (CK), alkaline phosphatase (ALP), amylase (AMI), total bilirubin (TB), triglycerides (TG) and glucose (GLU) did not allow differentiating exudates from transudates.

Whilst these cells present no specific markers from known cell lineages, they do share some homology with bone marrow-derived or adipose tissue-derived human mesenchymal stem cells (CD9, CD10, CD29, CD146, CD166, HLA-1). We studied the role of hospicells in ovarian carcinoma progression. In vitro, these cells had no effect on the growth of human ovarian carcinoma cell lines OVCAR-3, SKOV-1 and IGROV-1. In vivo, their co-injection with adenocarcinoma cells enhanced tumor growth whatever the tumor model used (subcutaneous and intraperitoneally established xenografts in athymic mice). In addition, their injection increased the development of ascites in tumor-bearing mice. Fluorescent macroscopy revealed an association between hospicells and ovarian adenocarcinoma cells within the tumor mass. Tumors obtained by coinjection of hospicells and human ovarian adenocarcinoma cells presented an increased microvascularization indicating that the hospicells could promote tumorigenicity of ovarian tumor cells in vivovia their action on angiogenesis. This effect on angiogenesis could be attributed to the increased HIF1alpha and VEGF expression associated with the presence of the hospicells. Collectively, these data indicate a role for these ascite-derived stromal cells in promoting tumor growth by increasing angiogenesis.

  17. Modulation of ConA-induced inflammatory ascites by histamine - short communication.

    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.

    Abstract We report the case of a 69‐year‐old man with dilated cardiomyopathy treated with a permanent catheter drainage system for diuretic resistant cardiac ascites. At 1 year follow‐up, the patient had no heart failure related hospitalisations, displayed improved quality of life measures and had incurred no complications related to the catheter. Permanent tunnelled catheters are widely used to treat malignant ascites but may also be considered for palliation of cardiac ascites.

    The concentrations of 23 plasma proteins were measured by radial immunodiffusion in the plasma and ascites of 17 patients with cirrhosis and four patients with intraperitoneal malignancies, to learn whether there is a selectivity in the movement of proteins from plasma into ascites, analogous to that of proteinuria. Additionally, since some of the proteins are involved in coagulation, we hoped to clarify the coagulopathy frequently seen following peritoneovenous shunting of ascites. Analysis was by groups: group 1 consisted of nine patients with cirrhosis with an ascites-total protein content less than 2.5 g/dl; group 2 consisted of eight patients with cirrhosis with ascites-total protein content greater than or equal to 2.5 g/dl; and group 3 consisted of four patients with malignant ascites. The ratio of the plasma concentration/ascites concentration ([P]/[A]) for each protein was calculated for each patient. In each group the median [P]/[A] for each protein was plotted against the natural logarithm of its molecular weight (In MW). For 21 of the 23 proteins, [P]/[A] showed a close linear relationship to In MW. Fibrogen and plasminogen showed significant (p < 0.0002) elevation above the regression line relating [P]/[A] to In MW. This indicates depletion of fibrinogen and plasminogen in ascites. The ascites in group 1 showed moderate selectivity, defined as the slope of the regression line (1.59), while groups 2 and 3 were essentialy nonselective (0.35 and 0.50). Fibrin-split products were elevated in all ascites but not in plasma, indicating either fibrinolysis or fibrinogenolysis within the ascites. A normal ratio for prothrombin suggests fibrinogenolysis may be the dominant mechanism. Thus the coagulopathy induced by LeVeen valve insertion may be in part secondary to the infusion of plasmin or a plasminogen activator into the circulation.

    Laparoscopic living donor nephrectomy (LLDN) is a minimally invasive technique for kidney procurement and was developed with the hope of reducing the disincentives associated with live renal donation. Compared with open donor nephrectomy (ODN), this alternative has many advantages including less postoperative pain and earlier return to work. Unfortunately, these benefits are sometimes negated by postoperative complications. Among these, chylous ascites (CA) is a rare but serious problem that is usually managed conservatively. We report the case of a living donor who developed CA refractory to initial conservative management and surgical treatment. We also discuss the role of surgery in the treatment of CA following LLDN.

    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.

    We prospectively evaluated the ascitic fluid (AF) polymorphonuclear cell (PMN) count, pH, and lactate concentration in single ascitic fluids from 60 patients to determine their relative predictive values for the immediate diagnosis of ascitic fluid infection. Nine of the 60 ascitic fluids were malignant. Of the remaining 51 samples, nine from cirrhotic patients were infected. The mean AF pH, lactate concentration, and PMN count in the infected group were 7.20 +/- 0.19, 80 +/- 51 mg/dl, and 18,199 +/- 19,650 cells/mm3, respectively, and all were significantly different from the corresponding values in noninfected ascites. Mean arterial blood-ascitic fluid (B-AF) pH and lactate gradients in the infected group were 0.23 +/- 0.17 and -46 +/- 31 mg/dl, respectively, and were significantly different from the corresponding values in noninfected ascites (p less than 0.05). Significant differences were not found between infected and malignant ascites, except for the AF PMN count (p less than 0.001). In cirrhosis with ascites, an AF pH less than or equal to 7.34 was the most specific single test (100%) and had the highest diagnostic accuracy (98%). In the larger group of patients with ascites of diverse etiology, a B-AF pH gradient greater than or equal to 0.10 or an AF PMN count greater than or equal to 500 cells/mm3 were the single tests with the highest diagnostic accuracy (92%). Combining an AF PMN count greater than 500 cells/mm3 with any of the other diagnostic criteria increased the specificity and diagnostic accuracy (up to 98%) compared to the best single criterion. Although our data support the use of a number of different combinations of AF measurements for the immediate diagnosis of infection, the simplest and most readily obtainable measurements are the pH and PMN count. Therefore, in the clinical setting we recommend the use of either an AF pH less than or equal to 7.34 or a B-AF pH gradient greater than or equal to 0.10 in combination with an AF PMN count

    In most experimental ascites tumours the growth rate decreases with increasing age and cell number. This decrease is caused by a prolongation of the cell cycle and an increasing accumulation of non-cycling cells in resting (or quiescent) G1 and G2 compartments. In cell-free ascitic fluid from the JB-1 ascites tumour in the plateau phase of growth lowmolecular-weight substances have been found which reversibly and specifically arrest JB-1 cells in G1 and G2. The present paper describes an in-vitro model for testing the effect of the humoral growth inhibitors contained in the ascitic fluid. The test system is based on synchronized JB-1 cells analysed by flow-through cytofluorometry. Addition to the synchronous cells of a ultrafiltrate (less than 50000 Daltons) of the JB-1 ascitic fluid was found to induce a complete, but temporary arrest of the cells at the G1-S border.

    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.

    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.

    A common problem in patients with chronic liver diseases and liver cirrhosis is the development of ascites. First line therapy for ascites is the restriction of sodium intake and a diuretic treatment. Paracentesis is indicated in patients with large compromising volumes of ascites. In selected cases, permanent drainage of ascites over prolonged periods of time may be indicated. In the case presented here, a 66-year-old male patient, who was hospitalized with liver cirrhosis caused by alcoholic abuse, required permanent drainage of ascites. After three weeks of continuous ascites drainage, he developed bacterial peritonitis. Conventional attempts to remove the catheter by transcutaneous pulling failed and we thus decided to perform a median laparotomy to remove the catheter surgically. Intraoperatively an adhesion of the ascites drain (a so called ‘basket catheter’) to the mesentery very close to the small intestine was found, approximately 50 mm distal of the ligament suspensorium duodeni (ligament of Treitz). The basket catheter used for this patient was especially designed to drain infections, not fluids. We solved the adhesion, removed the basket catheter, placed a new surgical drain and finished the operation. The patient developed a rupture of his abdominal fascia suture 12 days later, which was caused by massive ascites and complicated by hepatorenal syndrome type I. The patient was taken to the operating theater again. After the second operation, the chronic liver failure decompensated and the patient died. Ascites caused by liver cirrhosis is still a medical challenge. The indication for the use of the correct percutaneous catheter for permanent paracentesis should be carefully considered. Some catheters are obviously not suited to drain ascites and may lead to fatal outcomes. PMID:24453504

    Vitamin B12 deficiency is widespread than assumed in population. At risk are older people, pregnant women, vegans, patients with renal and intestinal diseases. Vitamin B12 deficiency can present with various hematological, gastrointestinal and neurological manifestations. In the population, the prevalence of vitamin B12 deficiency in younger people is 5% to 7% which is less compared to elderly people. In developing countries, deficiency is much more common, starting in early life and persisting across the life span. Here, we present a 16-year-old female patient presenting with ascites since 2 months who was subsequently investigated and diagnosed to have nutritional megaloblastic anaemia secondary to vitamin B12 deficiency after exclusion of other infective, neoplastic, autoimmune and inflammatory diseases. Inspite, patient was treated with antitubercular drugs but she did not respond. After supplementation of Vitamin B12, ascites responded well. Inadequate intake due to low consumption of animal source foods is the main cause of low serum vitamin B12 in younger adults and likely the main cause in poor population worldwide.

    Although lymphocyst (retroperitoneal lymphocele) is not an uncommon complication after retroperitoneal surgery, with a reported incidence ranging from 0.6% to 48%, the occurrence of chylous ascites is a rare phenomenon. Most reports are anecdotal, and hospital records list the incidence of diagnosis as 0.001% of admissions. Diagnosis of chylous ascites is usually not difficult, inasmuch as aspiration and chemical analysis of the fluid yield the answer. Visualization of retroperitoneal fluid collection by computerized tomography or ultrasonography, however, does always raise the possibility of recurrence of tumor in cases where the primary operation was for cancer. Treatment of smaller lesions can be expectant. Respiratory exercises causing an increase in negative intrathoracic pressure may aid in the movement of fluid through the lymphatics. For larger collections, elemental diets and total parenteral nutrition are also often enough, but surgery is sometimes required. Simple insertion of a peritoneovenous shunt, as in this patient, can be as effective as major operations such as identification and ligation of the offending lymphatic or marsupialization of the cyst.

    Ovarian cancer is a major cause of cancer mortality among women, largely due to late diagnosis of advanced metastatic disease. More extensive molecular analysis of metastatic ovarian cancer is needed to identify post-translational modifications of proteins, especially glycosylation that is particularly associated with metastatic disease to better understand the metastatic process and identify potential therapeutic targets. Glycoproteins in ascites fluid were enriched by affinity binding to lectins (ConA or WGA) and other affinity matrices. Separate glycomic, proteomic, and glycopeptide analyses were performed. Relative abundances of different N-glycan groups and proteins were identified from ascites fluids and a serum control. Levels of biomarkers CA125, MUC1, and fibronectin were also monitored in OC ascites samples by Western blot analysis. N-Glycan analysis of ascites fluids showed the presence of large, highly fucosylated and sialylated complex and hybrid glycans, some of which were not observed in normal serum. OC ascites glycoproteins, haptoglobin, fibronectin, lumican, fibulin, hemopexin, ceruloplasmin, alpha-1-antitrypsin, and alpha-1-antichymotrypsin were more abundant in OC ascites or not present in serum control samples. Further glycopeptide analysis of OC ascites identified N- and O-glycans in clusterin, hemopexin, and fibulin glycopeptides, some of which are unusual and may be important in OC metastasis.

    A 65-year-old man with chronic hepatitis C and no history of alcohol abuse was admitted to our liver unit for the recent development of massive ascites and presumed hepatorenal syndrome. In the preceding two weeks, he had received medical treatment for acute pancreatitis and cholecystitis. Abdominal paracentesis demonstrated a cloudy, orange peritoneal fluid, with total protein concentration 3.6 g/dl, serum-ascites albumin gradient 1.0 g/dl, and ratios of ascites-serum bilirubin and amylase approximately 8:1. Diagnostic imaging demonstrated no pancreatic pseudocysts. Ten days later, at laparotomy, acalculous perforation of the gallbladder was identified. After cholecystectomy, amylase concentration in the ascitic fluid dropped within a few days to 40% of serum values; ascites disappeared within a few weeks. We conclude that in the presence of a perforated gallbladder, pancreatobiliary reflux was responsible for this unusual combination of choleperitoneum and pancreatic ascites, which we propose to call pancreatobiliary ascites.

    Malignant ascites, occurring in advanced stages of cancer, is linked with poor prognosis and can cause invalidating symptoms. Physiopathological mechanisms of ascites formation are complex and have yet to be fully elucidated. In most cases, ascites is due to peritoneal carcinomatosis in which vascular permeability is enhanced by VEGF production while lymphatic drainage decreases. Ascites can also be secondary to portal hypertension, for example in case of multiple liver metastases, or due to lymphatic obstruction. While paracentesis and diuretics are commonly used, their efficiency has never been compared in a randomized controlled study. Paracentesis brings immediate but temporary relief in over 90% of cases, and implies multiple hospitalizations. Literature reports ascites control by aldosterone alone or in association with furosemide. But, available data is controversial, and there is no predictive factor to identify patients that respond to diuretic treatment. The indication of diuretic treatment is left to the appreciation of physicians. Existing recommendations are old, and practices influenced by results obtained in non-neoplastic ascites. Additional evidences are required before guidelines can be established for the palliative management of malignant ascites.

    Purpose Natural killer T (NKT) cells recognize lipid antigen presented by CD1 molecules. NKT cells can both directly, through cytotoxicity, and indirectly, through activation of other effector cells, mediate anti-tumor immunity. However, it has been shown that tumor associated lipids are frequently shed into the tumor microenvironment, which can mediate immunosuppressive activity. Given that ovarian cancer associated ascites has been reported to have increased levels of gangliosides, we examined the effect of tumor associated and other ascites on CD1d-mediated antigen presentation to NKT cells. Experimental Design To investigate the effects of ascites on NKT cell activation, we pretreated CD1d-expressing cells with the ascites and measured their ability to stimulate cytokine production in NKT cells. To determine whether antigen processing or editing was necessary, CD1d-Ig-based artificial Antigen Presenting Cells (aAPC) were also incubated with ascites. In addition, to examine specificity, we analyzed whether ascites fluid could influence the activation of classical CD8+ T cells. Results Pretreatment of CD1d-expressing cells with ascites from the majority of patients inhibited the cells’ ability to stimulate/activate NKT cells in a dose-dependent manner. Ascites treatment also partially blocked the ability of α-GalCer loaded CD1d-Ig-based artificial Antigen Presenting Cells (aAPC) to activate NKT cells. In addition, our data demonstrate that treatment with ascites does not inhibit HLA-A2 mediated activation of classical CD8+ T cells. Conclusions Together, these data suggest that ovarian and other cancers may have developed immune evasion mechanisms specifically targeting the CD1/NKT cell system. PMID:19047090

  18. Prognostic significance of IL-6 and IL-8 ascites levels in ovarian cancer patients

    PubMed Central

    2011-01-01

    Background The acellular fraction of epithelial ovarian cancer (EOC) ascites promotes de novo resistance of tumor cells and thus supports the idea that tumor cells may survive in the surrounding protective microenvironment contributing to disease recurrence. Levels of the pro-inflammatory cytokines IL-6 and IL-8 are elevated in EOC ascites suggesting that they could play a role in tumor progression. Methods We measured IL-6 and IL-8 levels in the ascites of 39 patients with newly diagnosed EOC. Commercially available enzyme-linked immunosorbent assay (ELISA) was used to determine IL-6 and IL-8 ascites levels. Ascites cytokine levels were correlated with clinicopathological parameters and progression-free survival. Results Mean ascites levels for IL-6 and IL-8 were 6419 pg/ml (SEM: 1409 pg/ml) and 1408 pg/ml (SEM: 437 pg/ml) respectively. The levels of IL-6 and IL-8 in ascites were significantly lower in patients that have received prior chemotherapy before the surgery (Mann-Whitney U test, P = 0.037 for IL-6 and P = 0.008 for IL-8). Univariate analysis revealed that high IL-6 ascites levels (P = 0.021), serum CA125 levels (P = 0.04) and stage IV (P = 0.009) were significantly correlated with shorter progression-free survival. Including these variables in a multivariate analysis revealed that elevated IL-6 levels (P = 0.033) was an independent predictor of shorter progression-free survival. Conclusion Elevated IL-6, but not IL-8, ascites level is an independent predictor of shorter progression-free survival. PMID:21619709

    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

    Ascites and abdominal pseudocysts (APC) are two rare complications that can occur following placement of a ventriculoperitoneal (VP) shunt. Both complications are characterized by abnormal intraperitoneal cerebrospinal fluid (CSF) collections. Although various factors have been implicated, the exact pathogenesis of the two conditions remains elusive. This paper presents two cases of VP shunt placement resulting from hydrocephaly. The first patient presented with generalized ascites and the other with APC, both of whom were six years old. APC and ascites after VP shunt placement are rare and distinct conditions; therefore, they may require different management strategies.

  1. Role of malignant ascites on human mesothelial cells and their gene expression profiles

    PubMed Central

    2014-01-01

    Background Malignant ascites is often present at diagnostic in women with advanced ovarian cancer (OC) and its presence is associated with a worse outcome. Human peritoneal mesothelial cells (HPMCs) are key components of malignant ascites. Although the interplay between HPMCs and OC cells is believed to be critical for tumor progression, it has not been well characterized. The purpose of this study was to assess the effect of ascites on HPMCs and clarify the role of HPMCs in OC progression. Methods Human OC ascites and benign peritoneal fluids were assessed for their ability to stimulate HPMC proliferation. Conditioned medium from ascites- and benign fluid-stimulated HPMCs were compared for their ability to attenuate apoptosis induced by TNF-related apoptosis-inducing ligand (TRAIL). We conducted a comparative analysis of global expression changes in ascites-stimulated HPMCs using Agilent oligonucleotide microarrays. Results As compared to benign peritoneal fluids, malignant ascites stimulated the proliferation of HPMCs. TRAIL-induced apoptosis was attenuated in OC cells exposed to conditioned medium from ascites-stimulated HPMCs as compared to OC cells exposed to conditioned medium from benign fluid-stimulated HPMCs. A total of 649 genes were differentially expressed in ascites-stimulated HPMCs. Based on a ratio of more than 1.5-fold and a P < 0.05, 484 genes were up-regulated and 165 genes were down-regulated in ascites-exposed HPMCs. Stimulation of HPMCs with OC ascites resulted in differential expression of genes mainly associated with the regulation of cell growth and proliferation, cell death, cell cycle and cell assembly and organization, compared to benign peritoneal fluids. Top networks up-regulated by OC ascites included Akt and NF-κB survival pathways whereas vascular endothelial growth factor (VEGF) pathway was down-regulated. Conclusions The results of this study not only provide evidence supporting the importance of the interplay between cancer

    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.

    Cirrhosis affects millions of people throughout the world. Two of the most serious complications of liver cirrhosis are ascites and spontaneous bacterial peritonitis (SBP). The development of ascites is related to the severity of portal hypertension and is an indicator of increased mortality. Although sodium restriction and diuretic therapy have proven effective, some patients may not respond appropriately or develop adverse reactions to diuretic therapy. In such cases, interventions such as transjugular intrahepatic portosystemic shunt (TIPS) placement are warranted. SBP is a complication of ascites that confers a very high mortality rate. Recognition and prompt treatment of this condition is essential to prevent serious morbidity and mortality. Initiation of prophylaxis in SBP remains controversial. Given the burden of liver cirrhosis on the health care system, ascites and SBP will continue to provide challenges for the primary care provider, hospitalist, internist, and gastroenterologist alike.

    This case report describes a three-year-old Swiss Braunvieh cow with ascites due to thrombosis of the caudal vena cava. Ultrasonography verified the ascites and revealed dilatation of the abdominal portion of the caudal vena cava (4.8 cm). It was presumed that the caudal vena cava was occluded by a thrombus or by perivenous compression cranial to the dilatation. Post mortem findings included: a massive accumulation of fluid in the abdominal cavity; a 15 cm long thrombus in the subphrenic region of the caudal vena cava; multiple pulmonary abscesses; severe thrombosis of the pulmonary vasculature; hepatic congestion; oedematous abomasal folds; and severe thrombophlebitis of the left jugular vein and both udder veins, due to poor intravenous injection technique. Ascites caused by thrombosis of the caudal vena cava is rare because collateral routes of venous return, including the udder veins, are usually established. It was therefore concluded that the ascites was attributable to bilateral thrombosis of the udder veins.

    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.

    Endotoxaemia was investigated by the Limulus assay in 42 cirrhotic patients with ascites and in 33 without ascites. The incidence of endotoxaemia in the former group (59.5%) was significantly (P less than 0.05) higher than in the latter (36.4%). Correlation between endotoxaemia and specific gravity and concentrations of total protein, albumin, and globulin in ascitic fluid was studied in the group with ascites. The specific gravity of ascites in 25 patients with endotoxaemia was significantly greater than that in 17 patients without endotoxaemia (P less than 0.01). The concentration of total protein in patients with endotoxaemia (13.95 +/- 7.18 milligram, mean +/- SD) was nearly twice as high (P less than 0.01) as in patients without endotoxaemia (7.49 +/- 3.60 milligram). The protein content of those who showed reactions greater or equal to 2(+) in the Limulus assay (16.78 +/- 7.14 milligram) was a significantly (P less than 0.05) higher than in those with 1(+) reaction (11.26 +/- 6.33 milligram). Moreover, the concentration of albumin in patients with endotoxaemia (7.68 +/- 4.60 milligram) was more than twice that of the patients without endotoxaemia (3.39 +/- 1.58 milligram, P less than 0.01). On the other hand, globulin concentration in patients with endotoxaemia was 1.6 times that of patients without endotoxaemia (P less than 0.01). Similar differences were noted between endotoxaemic and non-endotoxaemic patients in the ascites-to-serum ratio in protein, albumin, and globulin. These results suggest that in liver cirrhosis endotoxaemia may cause an increase in protein concentrations in ascitic fluid, and that it may be a precipitating factor in the formation of ascites.

    Pregnancy-associated plasma protein-A (PAPP-A) stimulates insulin-like growth factor (IGF) action through proteolysis of IGF-binding protein (IGFBP)-4. In experimental animals, PAPP-A accelerates ovarian tumor growth by this mechanism. To investigate the effect of PAPP-A in humans, we compared serum and ascites from 22 women with ovarian carcinoma. We found that ascites contained 46-fold higher PAPP-A levels as compared to serum (P < 0.001). The majority (80%) of PAPP-A was enzymatically active. This is supported by the finding that ascites contained more cleaved than intact IGFBP-4 (P < 0.03). Ascites was more potent than serum in activating the IGF-I receptor (IGF-IR) in vitro (+31%, P < 0.05); in 8 of 22 patients by more than two-fold. In contrast, ascites contained similar levels of immunoreactive IGF-I, and lower levels of IGF-II (P < 0.001). Immunohistochemistry demonstrated the presence of IGF-IR in all but one tumor, whereas all tumors expressed PAPP-A, IGFBP-4, IGF-I and IGF-II. Addition of recombinant PAPP-A to ascites increased the cleavage of IGFBP-4 and enhanced IGF-IR activation (P < 0.05). In conclusion, human ovarian tumors express PAPP-A, IGFBP-4 and IGFs and these proteins are also present in ascites. We suggest that both soluble PAPP-A in ascites and tissue-associated PAPP-A serve to increase IGF bioactivity and, thereby, to stimulate IGF-IR-mediated tumor growth. PMID:26336825

    To investigate the long-term probability of the appearance of the first episode of spontaneous bacterial peritonitis in cirrhosis with ascites and to identify predictors of this complication, we closely followed throughout their illness 127 patients consecutively admitted to our unit for the treatment of an episode of ascites without prior spontaneous bacterial peritonitis (follow-up period: 21 +/- 22 mo). Thirteen patients (10%) had the first spontaneous bacterial peritonitis episode during follow-up. The appearance probability of this complication is 11% at 1 yr and 15% at 3 yr. Thirty-three variables obtained at admission (including clinical data, standard liver and kidney function test results, ascitic fluid protein concentrations and hemodynamic parameters) were analyzed in relation to their value in predicting spontaneous bacterial peritonitis development. In univariate analysis (Kaplan-Meier curves) five variables reached statistical significance (p less than 0.05) as predictive factors for the development of the first spontaneous bacterial peritonitis episode. These five variables were poor nutritional status, increased serum bilirubin levels, increased serum AST levels, decreased prothrombin activity and reduced total protein concentration in ascitic fluid. When these five variables were introduced in a multivariate analysis, only the ascitic fluid protein concentration was found to correlate independently with spontaneous bacterial peritonitis development (p = 0.002). The probability of first spontaneous bacterial peritonitis after 3 yr of follow-up was 24% and 4% in patients with ascitic fluid protein content lower than 1 gm/dl and greater than or equal to 1 gm/dl, respectively.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1505916

    We describe the strategy, which allows curing experimental mice engrafted with Krebs-2 ascites. The strategy is based on the facts that i) Krebs-2 tumor-initiating stem cells (TISCs) are naturally capable of internalizing fragments of extracellular double-stranded DNA (dsDNA); ii) upon delivery into TISCs, these dsDNA fragments interfere with the on-going DNA repair process so that TISCs either die or lose their tumorigenic potential. The following 3-step regimen of therapeutic procedures leading to eradication of Krebs-2 ascites is considered. Firstly, three timed injections of cyclophosphamide (CP) exactly matching the interstrand cross-link (ICL) repair phases that lead to synchronization of ascites cells in late S/G2/M. Secondly, additional treatment of ascites 18 hours post each CP injection (at NER/HR transition timepoint) with a composite dsDNA-based preparation interfering with the NER and HR repair pathways, so that tumorigenic properties of ascites cells are compromised. Thirdly, final treatment of mice with a combination of CP and dsDNA injections as ascites cells undergo apoptotic destruction, and the surviving TAMRA+ TISCs arrested in late S/G2/M phases massively enter into G1/S, when they regain sensitivity to CP+dsDNA treatment. Thus, this regimen assures that no viable cells, particularly Krebs-2 TISCs, remain. PMID:26872383

    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

    Congenital chylous ascites in the neonatal period is a rare entity. Total parenteral nutrition (TPN), medium chain triglyceride (MCT)-based diet, octreotide and repeated paracentesis are regarded as appropriate medical treatment for congenital chylous ascites, and surgery is recommended when conservative therapy has failed. We present two cases in which ascites were confirmed via an abdominal sonogram and diagnostic paracentesis. In our clinical experience, rice soup combined with PN can be a safe and effective intervention. PMID:27440699

    The current model of picornavirus protein formation implies that initiation of protein synthesis occurs at a single site on the viral RNA, and that the large polypeptide formed is later cleaved. A direct test of this model was made in vitro by studying the incorporation of [(35)S]methionine from rabbit liver Met-tRNA(M) (Met) and fMet-tRNA(F) (Met) into encephalomyocarditis virus RNA-coded proteins in extracts of Ehrlich ascites cells. The incorporation of N-formylmethionine was complete within 5 min, while utilization of Met-tRNA(M) (Met) continued for 20 min. Tryptic digests of [(35)S]methionine-labeled products from Met-tRNA(M) (Met) analyzed by anion-exchange chromatography yielded more than 30 peptides, as compared to about 15 [(35)S]methionine-labeled peptides from purified encephalomyocarditis virus. In contrast, products labeled with fMet-tRNA(F) (Met) yielded one major (26)S-labeled tryptic peptide. The N-terminal location of methionine in this peptide was verified by Edman degradation. One predominant N-terminal tryptic peptide was also obtained with fMet-tRNA(F) (Met) when mouse Elberfeld and mengo-virus RNAs were used as messengers. On the basis of N-terminal compared with internal labeling of the products, no evidence for in vitro post-translational cleavage was found. The results are consistent with a single initiation site for synthesis of picornavirus proteins.

    Chylous ascites (CA) is a rare postoperative complication. It also occurs in pancreatic surgery and can influence the patient’s prognosis after pancreatic resection. There are few studies focusing on CA following pancreatic resection. We aimed to evaluate the incidence and risk factors of CA following pancreatic resection. Patients who underwent pancreatic resection from the year 2007 to 2013 were retrospectively reviewed. The diagnosis of CA was based on the presence of a non-infectious milky or creamy peritoneal fluid greater than 100 ml/day with a triglyceride concentration ≥110 mg/dl. The incidence and possible risk factors following pancreatic resection were evaluated. In this study, 1921 patients who underwent pancreatic resection were included. 49 patients developed CA. The overall incidence was 2.6 percent (49 out of 1921). The incidence following pancreaticoduodenectomy and distal pancreatectomy was much higher (35 out of 1241, 12 out of 332, respectively). A multivariable analysis demonstrated that manipulating para-aortic area and superior mesenteric artery root area; retroperitoneal invasion; focal chronic pancreatitis and early enteral feeding were the independent risk factors for CA after pancreatic surgery. In conclusion, CA is a rare complication after pancreatic resection. Some clinicopathological factors were associated with the development of CA following pancreatic resection. PMID:26064374

    A study of the enzymes of the glycogen pathway in Novikoff ascites hepatoma shows that glycogen synthetase has the lowest activity and that the tumour contains no high-Km soluble glucokinase. However, incubation of tumour cells with metabolizable sugars in vitro, or intraperitoneal administration of glucose into the tumour-bearing rat, results in glycogen accumulation by the tumour cells. Glycogen synthesis in the tumour is supported by aerobically produced ATP but is decreased anaerobically and by uncouplers of oxidative phosphorylation. Absence of Pi from the incubation medium increases glycogen synthesis and decreases glycolysis. The optimum temperature for glycogen synthesis is 37°. The capacity of the intact tumour cell to degrade deposited glycogen is low, but is accelerated by 2,4-dinitrophenol. Tumour homogenates prepared after osmotic shock do not incorporate [14C]glucose into glycogen. The glucose moiety of glucose 1-phosphate and of UDP-glucose is incorporated into glycogen by the homogenates and the incorporation of glucose 1-phosphate is greatly enhanced by AMP. Glucose 6-phosphate is a poor precursor of glycogen in the homogenate system, probably because it inhibits activation of phosphorylase b by AMP. PMID:4291492

    Background Chylous ascites is the pathologic leakage of triglycerides-rich lymphatic fluid into the peritoneal cavity. Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery. Methods This study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT), and total parenteral nutrition (TPN) were also analyzed in this study. Results Complete clinical success was reached earlier in patients treated with somatostatin (P<0.001). The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN) + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038). Conclusion In treating chylous ascites, EN + MCT instead of TPN was the best nutrition support. Moreover, somatostatin or its analog octreotide should be used immediately. The treatment with somatostatin in combination with EN + MCT is recommended in the conservative treatment of postoperative chylous ascites. PMID:27143902

    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

    An ascitic microenvironment can condition the immune response of cells from cirrhotic patients with spontaneous bacterial peritonitis. To characterize this response, we determined the cytokine concentrations in ascitic fluid and analyzed the phenotype and function of ascitic leukocytes at diagnosis and after antibiotic-induced resolution in sterile ascites and ascitic fluid of 2 spontaneous bacterial peritonitis variants: positive and negative bacteriological culture. At diagnosis, a high concentration was found of IL-6 and IL-10 in the ascitic fluid from negative and positive bacteriological culture. The IL-6 concentration correlated with the percentage of neutrophils (R = 0.686, P < 0.001). In this context, positive and negative culture neutrophils had an impaired oxidative burst, and, after the antibiotic, the negative culture spontaneous bacterial peritonitis burst was fully recovered. Higher concentrations of IL-6 and IL-10 correlated with the presence of low granular CD 14(low) macrophages (R = -0.436, P = 0.005 and R = 0.414, P = 0.007, respectively). Positive culture spontaneous bacterial peritonitis macrophages expressed the lowest levels of CD16, CD86, CD11b and CD206, and HLA-DR, suggesting an impaired global function. Treatment increased all markers on the positive culture macrophages and CD11b and CD86 on negative culture macrophages. In negative culture spontaneous bacterial peritonitis, this increase was accompanied by phagocytic function recovery. The antibiotics then reverted the marker levels on positive and negative culture macrophages to the levels on sterile ascitis macrophages and restored ascitic negative culture cell function.

    Cell-free and concentrated ascites reinfusion therapy (CART) is expected to improve symptoms associated with refractory ascites of the decompensated liver cirrhosis patients. The aim of this study was to evaluate the safety and efficacy of the CART system performed on the decompensated liver cirrhosis patients. In this retrospective observational study, we evaluated 24 CART processes performed on 11 patients with decompensated liver cirrhosis. We evaluated the effectiveness and adverse events during CART procedures. The amounts of collected and concentrated ascites were 4491.7 ± 2222.8 mL (mean ± SD), respectively, and the concentration ratio was 22.4 ± 15.3 times, respectively. The amount of collected protein in ascites was 2.3 ± 0.5 g/dL, and concentration ratio of protein was 8.2 ± 9.4 times. Serum protein level was not significantly different between before and after CART sessions. Thus, CART allowed for the reduction of doses of albumin preparations (Alb) to be administered. CART has been reported to cause two adverse reactions: elevation of body temperature and decrease in blood pressure. In our study, decreased blood pressure was not observed even in patients with > 5 L of ascites drained. Although a transient elevation in body temperature was seen in only one patient, this febrile patient immediately returned to normal body temperature with the use of NSAIDs. In patients with refractory ascites of decompensated liver cirrhosis in whom complete cure cannot be expected, CART improves their QOL and, in terms of medical economy, allows for the reduction of doses of Alb. CART can be effectively applied as a palliative procedure for refractory ascites of decompensated liver cirrhosis patients. PMID:27523078

    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

    The variation in the DNA distribution in the JB-1 and the Lla2 ascites tumour was investigated by means of flow microfluorometry (FMF) in the plateau stage and during the initiation of the regenerative growth induced by percutaneous aspiration. The study showed that a considerable influx of cells with G1DNA content into the S phase occurred in both tumours about 10 hr after aspiration. In the JB-1 tumour, these initial regenerative changes could be reversibly blocked by injections of cell-free plateau JB-1 ascitic fluid or an ultrafiltrate of this ascites. In contrast to these observations no delay in the regenerative changes was observed in the L1a2 tumour after treatment with JB-1 ascites or the ultrafiltrate. The study supports the assumption of a specific growth regulation of the JB-1 ascites tumour and emphasizes the suitability of FMF analyses in cell-kinetic studies in which short-term fluctuations take place in the distribution of cells with different DNA content.

    To assess their accuracies as markers for malignancy, we assayed alpha 2-macroglobulin, C1-inhibitor, alpha 1-protease inhibitor, and total proteins in ascites and plasma from patients with gastrointestinal cancer (n = 15) and non-malignant liver disease (n = 13), using functional and immunologic assays. For all inhibitors and total proteins determined in ascites, the values in the cancer group were significantly higher than the corresponding values in the group with non-malignant liver disease. The diagnostic accuracy for differentiating malignancy-related from non-malignant ascites was 93% for a alpha 1-protease inhibitor value > or = 50% of the pool plasma value and 90% for alpha 2-macroglobulin > or = 16%, C1-inhibitor > or = 40% (all functional assays), and total proteins > or = 20 g/l (biuret). In conclusion, functional assays for alpha 2-macroglobulin, C1-inhibitor, and alpha 1-protease inhibitor and determination of total proteins in ascites appeared to be very informative tests for the differential diagnosis of ascites. The test for alpha 1-protease inhibitor gave higher specificity (92% versus 77%) and likelihood ratio for a positive test (12 versus 4) compared with the other tests.

    We describe a case of chylous ascites with strangulated ileus, and review all 22 cases (including our case) of chylous ascites with strangulated ileus reported in the English and Japanese literature. The patient we describe was a 51-year-old woman with medical history of radiotherapy for cervical cancer of the uterus 15 months prior to being admitted to our hospital with abdominal pain after consuming a meal. A computed tomography (CT) scan revealed ascites, expansion of the small intestine, and whirl sign. Laparotomy revealed chylous ascites with an incarcerated internal hernia of the small intestine, which was released without intestinal resection. In our case the postoperative phase was uneventful, and as in the other 21 literature cases reviewed, treatment by either detorsion, release of the incarcerated internal hernia, or incision of the adhesion band without intestinal resection resulted in rapid improvement in the color of the intestine. It is considered that minimally invasive laparoscopic laparotomy should be selected as the treatment of first choice, because the degree of strangulation is slight in cases where chylous ascites is associated with strangulated ileus.

    Bacterial infections, most commonly spontaneous bacterial peritonitis in patients with ascites, occur in one third of admitted patients with cirrhosis, and account for a 4-fold increase in mortality. Bacteria are isolated from less than 40% of ascites infections by culture, necessitating empirical antibiotic treatment, but culture-independent studies suggest bacteria are commonly present, even in the absence of overt infection. Widespread detection of low levels of bacteria in ascites, in the absence of peritonitis, suggests immune impairment may contribute to higher susceptibility to infection in cirrhotic patients. However, little is known about the role of ascites leukocyte composition and function in this context. We determined ascites bacterial composition by quantitative PCR and 16S rRNA gene sequencing in 25 patients with culture-negative, non-neutrocytic ascites, and compared microbiological data with ascites and peripheral blood leukocyte composition and phenotype. Bacterial DNA was detected in ascitic fluid from 23 of 25 patients, with significant positive correlations between bacterial DNA levels and poor 6-month clinical outcomes (death, readmission). Ascites leukocyte composition was variable, but dominated by macrophages or T lymphocytes, with lower numbers of B lymphocytes and natural killer cells. Consistent with the hypothesis that impaired innate immunity contributes to susceptibility to infection, high bacterial DNA burden was associated with reduced major histocompatibility complex class II expression on ascites (but not peripheral blood) monocytes/macrophages. These data indicate an association between the presence of ascites bacterial DNA and early death and readmission in patients with decompensated cirrhosis. They further suggest that impairment of innate immunity contributes to increased bacterial translocation, risk of peritonitis, or both. PMID:25781164

    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. PMID:27136008

    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 flow cytometric in vivo chalone assay is described. Transplantation of old JB-1 ascites tumour cells to new hosts induced an influx of tumour cells, with G1 DNA content, to the S phase. This induction could be reversibly and specifically blocked by injections of an ultrafiltrate of old JB-1 ascites fluid. The method described is superior to a previously published in vivo chalone assay using regenerating ascites tumours. Owing to a reduced variability in time of onset of DNA synthesis, a smaller scatter of observations is achieved and thus the number of mice per group may be reduced using the new method. In contrast to the older technique, the present one does not necessitate killing of mice during the observation period.

    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.

    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.

    Different forms of sarcoma (solid or ascitic) often pose a critical medical situation for pediatric or adolescent group of patients. To date, predisposed genetic anomalies and related changes in protein expression are thought to be responsible for sarcoma development. However, in spite of genetic abnormality, role of tumor microenvironment is also indispensable for the evolving neoplasm. In our present study, we characterized the deferentially remodeled microenvironment in solid and ascitic tumors by sequential immunohistochemistry and flowcytometric analysis of E-cdaherin, N-cadherin, vimentin, and cytokeratin along with angiogenesis and metastasis. In addition, we considered flowcytometric apoptosis and CD133 positive cancer stem cell analysis. Comparative hemogram was also considered as a part. Our investigation revealed that both types of tumor promoted neovascularization over time with sign of local inflammation. Invasion of neighboring skeletal muscle by solid sarcoma was more frequent than its ascitic counterpart. In contrary, rapid and earlier cadherin switching (E-cadherin to N-cadherin) in ascitic sarcoma made them more aggressive than that of solid sarcoma and helped to early metastasize distant tissue like liver through the hematogenous route. Differential cadherin switching and infidelity of cytokeratin expression in Vimentin positive sarcoma also influenced the behavior of ascitic CD133+ cancer initiating cell pool with respect to CD133+ cells housed in solid sarcoma. Therefore our study concludes that differential cadherin switching program and infidelity of intermediate filaments in part, sharply discriminate the severity and metastatic potentiality of either type of sarcoma accompanying with CD133+ cellular repertoire. Besides, tumor phenotype-based dichotomous cadherin switching program could be exploited as a future drug target to manage decompensated malignant ascitic and solid sarcoma.

    In the present study, the root nodules of Premna herbacea Roxb. (PH) was investigated for its in vitro cytotoxicity and in vivo antitumor activity. Two extracts, aqueous and alcoholic; two fractions of alcoholic extract, ethyl acetate and butanol fractions were screened for their in vitro cytotoxicity by brine shrimp lethality (BSL) assay, trypan blue exclusion assay and MTT assay. Alcoholic extract and its ethyl acetate fraction were found to be the most effective in BSL assay, trypan blue exclusion assay. In vivo antitumor activity was screened in the Ehrlich ascites carcinoma (EAC) model and the Dalton lymphoma ascites (DLA) model. The extracts and the fractions were tested at two dosages (250 and 500 mg/kg) by intraperitoneally (i.p.) route on every alternate day upto 13th day. Cisplatin was used as positive control in both studies in single dose (day 1) 3.5 mg/kg by i.p. route. In EAC model, ascites tumor was induced by inoculating 2.5 million of EAC cells i.p. alcoholic extract at 500 mg/kg was the most effective in elevating MST, reduction in body weight in EAC induced tumor. Only the effective extract i.e., alcoholic extract were studied for hematological and antioxidant parameter. It showed a restoring effect on altered hematological parameters and a significant improvement in biochemical parameters at 250 mg/kg dose of alcoholic extract.

Both the extracts and the fractions possessed potent antitumor activity against solid tumor models by significantly reducing the solid tumor weight and volume. PMID:21920724

    We studied antitumor properties of modified detonation nanodiamonds loaded with doxorubicin on in vivo model of Ehrlich ascites carcinoma. The type of tumor development and morphological characteristics of the liver, kidneys, and spleen were evaluated in experimental animals. Modified nanodiamonds injected intraperitoneally produced no antitumor effect on Ehrlich carcinoma. However, doxorubicin did not lose antitumor activity after sorption on modified nanodiamonds.

    Three cases of neonatal chylous ascites (CCA) were managed in the neonatal unit, University Hospital, Kuala Lumpur, over the past 9 years. Fetal ascites and polyhydramnios were the sole abnormalities detected in all three babies by antenatal ultrasonography. They were born at 36 weeks' gestation and their birth weights ranged from 3.0 kg to 3.8 kg. All three infants had abdominal distension at birth. Milky ascitic fluid was obtained after starting enteral feedings. Analysis of the ascitic fluid revealed a raised white blood cell count (predominantly lymphocytic) and triglycerides (1.4 - 3.8 mmol/l), cholesterol (1.6 - 2.8 mmol/l), and protein levels (25 - 41 g/l). Conservative management with skimmed milk and medium-chain triglycerides in one infant and Pregestimil in another was instituted. these two infants with CCA were clinically normal when reviewed at 19 months and 3.5 years of age. The third infant had a gut malrotation and associated pyloric septum; he died from complications of a laparotomy. The literature on this rare condition is reviewed.

    Human ovarian cancer, the leading cause of death from gynecologic malignancy, tends to remain localized to the peritoneal cavity until late in the disease. In established disease, ascitic fluid accumulates in the peritoneal cavity. We have previously demonstrated that this ascitic fluid is a potent source of in vitro mitogenic activity including at least one unique growth factor. We now report that the human ovarian adenocarcinoma line, HEY, can be induced to grow intraperitoneally in immunodeficient nude mice in the presence (23/28 mice), but not absence (0/21 mice) of ascitic fluid from ovarian cancer patients. Ascitic fluid from patients with benign disease did not have similar effects on intraperitoneal growth of HEY cells (1/15 mice). Once tumors were established by injections of exogenous ascitic fluid, they could progress in the absence of additional injections of ascitic fluid. The mice eventually developed ascitic fluid which contained potent growth factor activity, suggesting that the tumors eventually produced autologous growth factors. This nude mouse model provides a system to study the action of ovarian cancer growth factors on tumor growth in vivo and to evaluate preclinically, therapeutic approaches designed to counteract the activity of these growth factors.

    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.

    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.

    Bacterial translocation in patients with cirrhosis induces a marked proinflammatory activity that may be different against viable bacteria or bacterial products. The aim of this study is to identify new markers of bacterial translocation by investigating bacterial-driven peptides and correlate their presence with the inflammatory response. Patients with cirrhosis and ascites were included. An analysis by two-dimensional polyacrylamide gel electrophoresis of ascitic fluid total protein from patients (n = 47) and from frequently detected bacterial strains was performed. Two-dimensional maps were digitally compared. The identification of possible markers was performed by mass spectrometry. TNF-alpha, IFN-gamma, IL-12, nitric oxide, and proteins of the complement and lipopolysaccharide-binding protein levels were measured in ascitic fluid samples of patients by enzyme-linked immunosorbent assay. Patients were distributed according to the presence (group I, n = 16) and absence (group II, n = 31) of serum and ascitic fluid bacterial DNA. Among clinical and analytical differences between groups, only mean arterial pressure was significantly higher in patients from group II. Identified bacterial peptides were associated with bacterial protection against immune defenses and included glyceraldehyde-3-phosphate dehydrogenase A, Porin OmpC, and HSP60. Eight patients from group I also showed bacterial peptides, whereas none from group II did. All studied mediators of immune activation were significantly higher in patients with bacterial DNA than in patients without bacterial DNA. TNF-alpha, IFN-gamma, and proteins of the complement were significantly increased in patients with bacterial peptides versus those without bacterial peptides. Bacterial peptide translocation is present in the ascitic fluid of a subgroup of patients with advanced cirrhosis and is associated with an increased immune response.

    Systemic lupus erythematosus (SLE) is an autoimmune disease and can cause multi-organ damage. Peritoneal involvement, also called lupus peritonitis, is a rare but sometimes fatal manifestation. Deposition of immune complexes consisting of immunoglobulin G and complement is considered to be involved in the pathogenesis of lupus peritonitis; however, it remains unknown whether inflammatory cytokines contribute to the pathology of this manifestation. Here we present two patients with treatment-resistant lupus peritonitis: a 37-year-old woman with a 26-year history of SLE who had been treated with prednisolone and cyclophosphamide followed by azathioprine and a 65-year-old woman with a 33-year history of SLE who had been treated with prednisolone alone. Both patients were admitted to our department because of abdominal distention. Computed tomography scans showed massive ascites. Ascitic fluid examinations of both patients showed leukocytosis with no evidence of malignancy or infection. After eliminating other causes for ascites, they were diagnosed with lupus peritonitis. Despite the intensified immunosuppressive therapy, they died of uncontrolled peritonitis several months after admission. Examinations of the ascites at admission also revealed a large content of interleukin (IL)-6, compared with other inflammatory cytokines, IL-1β and tumor necrosis factor-α. In fact, the ascitic IL-6 levels of these two patients were 12,389 pg/mL and 5,486 pg/mL, much higher than their serum IL-6 levels of 36 pg/mL and 140 pg/mL, respectively. We therefore suggest that IL-6 may contribute to the pathogenesis of lupus peritonitis and that the inhibition of IL-6 signaling may provide a novel therapeutic strategy for lupus peritonitis.

    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.

  15. Ovarian cancer ascites increase Mcl-1 expression in tumor cells through ERK1/2-Elk-1 signaling to attenuate TRAIL-induced apoptosis

    PubMed Central

    2012-01-01

    Background Ascites may affect the progression of ovarian cancer (OC). In particular, soluble factors present in OC ascites can create a protective environment for tumor cells that promote de novo resistance to drug- and death receptor-induced apoptosis. However, the underlying molecular mechanisms responsible for ascites-induced drug resistance are not well characterized. Methods Using human OC cell lines and tissues microarrays of human OC biopsies, we assessed the mechanism by which OC ascites increase Mcl-1 expression using Western blots, chemical inhibitors of ERK and small-inhibitory RNA treatments. Results In the present study, we found that both Mcl-1 mRNA and protein levels were upregulated within 2 h upon treatment of OC cells with ascites obtained from women with advanced OC. In contrast, the expression of other Bcl-2 family antiapoptotic members such as Bcl-2 and Bcl-XL was not affected by ascites. An increase of Mcl-1 expression was consistently observed across different ascites from women with advanced serous OC. The knockdown of Mcl-1 significantly blocked ascites-induced Mcl-1 upregulation and ascites-mediated inhibition of TRAIL-induced apoptosis. Ascites induced a rapid phosphorylation of ERK1/2 and Elk-1 transcription factor. Furthermore, we found that ERK1/2 inhibition or Elk-1 knockdown was sufficient to block ascites-induced Mcl-1 expression. In high grade serous OC, we found a positive correlation between phosphorylated ERK1/2 and Mcl-1 expression. Conclusions These results indicate that ascites-induced ERK1/2/Elk-1 signaling is critical for Mcl-1 expression and for the ascites-mediated attenuation of TRAIL-induced apoptosis. The ERK1/2/Elk-1/Mcl-1 pathway represents a novel mechanism by which ascites induce de novo TRAIL resistance in OC cells. PMID:23158473

  16. The prosurvival activity of ascites against TRAIL is associated with a shorter disease-free interval in patients with ovarian cancer

    Background The production of ascites is a common complication of ovarian cancer. Ascites constitute a unique tumor microenvironment that may affect disease progression. In this context, we recently showed that ovarian cancer ascites may protect tumor cells from TRAIL-induced apoptosis. In this study, we sought to determine whether the prosurvival effect of ascites affects disease-free intervals. Methods Peritoneal fluids were obtained from 54 women undergoing intra-abdominal surgery for suspected ovarian cancer (44 cancers and 10 benign diseases). The ability of peritoneal fluids to protect from TRAIL was assessed in the ovarian cancer cell line CaOV3, and IC50 were determined. The anti-apoptotic activity of 6 ascites against cisplatin, paclitaxel, doxorubicin, etoposide and vinorelbine was also assessed in CaOV3 cells, and the prosurvival activity of two ascites was assessed in 9 primary ovarian cancer cultures. Results Among the 54 peritoneal fluids tested, inhibition of TRAIL cytotoxicity was variable. Fluids originating from ovarian cancer were generally more protective than fluids from non-malignant diseases. Most of the 44 ovarian cancer ascites increased TRAIL IC50 and this inhibitory effect did not correlate strongly with the protein concentration in these ascites or the levels of serum CA125, a tumor antigen which is used in the clinic as a marker of tumor burden. The effect of ascites on cisplatin- and paclitaxel-induced cell death was assessed with 4 ascites having inhibitory effect on TRAIL-induced cell death and 2 that do not. The four ascites with prosurvival activity against TRAIL had some inhibitory on cisplatin and/or paclitaxel. Two ovarian cancer ascites, OVC346 and OVC509, also inhibited TRAIL cytotoxicity in 9 primary cultures of ovarian tumor and induced Akt activation in three of these primary cultures. Among a cohort of 35 patients with ascites, a threshold of TRAIL IC50 with ascites/IC50 without ascites > 2 was associated with shorter

    Background Transthyretin (TTR), a traditional biomarker for nutritional and inflammatory status exists in different molecular variants of yet unknown importance. A truncated form of TTR has recently been described to be part of a set of biomarkers for the diagnosis of ovarian cancer. The main aim of the study was therefore to characterize differences in microheterogeneity between ascitic fluid and plasma of women affected with ovarian cancer and to evaluate the tumor site as the possible source of TTR. Methods Subjects were 48 women with primary invasive epithelial ovarian cancer or recurrent ovarian carcinoma. The control group consisted of 20 postmenopausal women. TTR and retinol-binding protein (RBP) levels were measured by enzyme-linked immunoassay (ELISA) and C-reactive protein (CRP) levels by a high-sensitivity latex particle turbidimetric assay. The molecular heterogeneity of TTR was analysed using immunoprecipitation and matrix-associated laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Presence of TTR in tumor tissue was determined with indirect peroxidase immunostaining. Results TTR and RBP (μg/ml) levels in serum were 148.5 ± 96.7 and 22.5 ± 14.8 in affected women compared to 363.3 ± 105.5 and 55.8 ± 9.3 in healthy postmenopausal women (p < 0.01). In ascitic fluid, levels were 1.02 ± 0.24 and 4.63 ± 1.57 μg/ml, respectively. The mean levels of TTR and RBP in serum showed a tendency to decrease with the severity of the disease and were lower in affected women whose CRP levels were > 40 mg/ml (p = 0.08 for TTR; p < 0.05 for RBP). No differences in TTR microheterogeneity were observed between TTR isolated from serum of affected and healthy women or from ascitic fluid. TTR occurred rather consistently in four variants. Mass signals were at 13758 ± 7, 13876 ± 13 (greatest intensity), 13924 ± 21 and 14062 ± 24 Da, representing native, S-cysteinylated, S-cysteinglycinylated and glutathionylated TTR, respectively.

The content of chylomicron in ascites decreased by restriction of dietary fat, although the ascites retention was resistant to salt restriction, diuretics and intravenous re-infusion of ascites. Lymphangiography revealed dysplasia of the retroperitoneal lymphatic system and dilatation of the thoracic duct. Main autopsy findings were liver cirrhosis (post-necrotic type) without malignancy and marked cystic dilatations of the lymphatic duct. The lymph congestion in the intestine was more remarkable in the subserosal space and the leakage of the chyle into the abdominal cavity was also proved by histological examination.

    Toll-like receptors (TLRs) are important molecules that stimulate the innate immunity in order to eradicate microbial pathogens, after which the adaptive immunity emerges. The involvement of TLRs in the action mechanism of OK-432, a bacterial preparation, was investigated in the locoregional treatment of malignant ascites from gastric cancer. The expression of TLRs in ascites cells was analyzed using reverse-transcription polymerase chain reaction specific for TLRs and by flow cytometry using anti-TLR2, -TLR4, -CD4, -CD8, and -CD11c antibodies. These measurements were compared with the locoregional response of OK-432 immunotherapy for malignant ascites, as well as TNF-alpha producing potential, which was measured by ELISA, of ascites cells stimulated in vitro with OK-432. It was observed that OK-432 immunotherapy for malignant ascites showed 8 positive (67%) and 4 negative responses with the tolerable adverse effects of fever elevation and abdominal pain. The TNF-alpha production of ascites cells by in vitro OK-432 stimulation was significantly higher in responder patients than in non-responders. The clinical responses were correlated with the expression of the TLR4 gene of ascites cells. The TNF-alpha-producing potential of ascites cells by in vitro OK-432 stimulation was dependent on the existence of a CD11c + TLR-4+ cell population in ascites cells. OK-432 was highly stimulatory for TNF-alpha production of ascites cells compared with other biological response modifiers of PSK and LEM. These results suggest that TLR-4 expression on ascites cells of a macrophage lineage is essential for ascites cells to produce TNF-alpha in relation to OK-432 stimulation and for subsequent positive clinical responses in locoregional immunotherapy using OK-432 for malignant ascites from gastric cancer.

    Tumor cells in ascites are a major source of disease recurrence in ovarian cancer patients. In an attempt to identify and profile the population of ascites cells obtained from ovarian cancer patients, a novel method was developed to separate adherent (AD) and non-adherent (NAD) cells in culture. Twenty-five patients were recruited to this study; 11 chemonaive (CN) and 14 chemoresistant (CR). AD cells from both CN and CR patients exhibited mesenchymal morphology with an antigen profile of mesenchymal stem cells and fibroblasts. Conversely, NAD cells had an epithelial morphology with enhanced expression of cancer antigen 125 (CA125), epithelial cell adhesion molecule (EpCAM) and cytokeratin 7. NAD cells developed infiltrating tumors and ascites within 12–14 weeks after intraperitoneal (i.p.) injections into nude mice, whereas AD cells remained non-tumorigenic for up to 20 weeks. Subsequent comparison of selective epithelial, mesenchymal and cancer stem cell (CSC) markers between AD and NAD populations of CN and CR patients demonstrated an enhanced trend in mRNA expression of E-cadherin, EpCAM, STAT3 and Oct4 in the NAD population of CR patients. A similar trend of enhanced mRNA expression of CD44, MMP9 and Oct4 was observed in the AD population of CR patients. Hence, using a novel purification method we demonstrate for the first time a distinct separation of ascites cells into epithelial tumorigenic and mesenchymal non-tumorigenic populations. We also demonstrate that cells from the ascites of CR patients are predominantly epithelial and show a trend towards increased mRNA expression of genes associated with CSCs, compared to cells isolated from the ascites of CN patients. As the tumor cells in the ascites of ovarian cancer patients play a dominant role in disease recurrence, a thorough understanding of the biology of the ascites microenvironment from CR and CN patients is essential for effective therapeutic interventions.

    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.

    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.

    BACKGROUND—Some cirrhotic patients with tense ascites who undergo paracentesis develop a circulatory dysfunction syndrome, manifested by an increase in plasma renin activity. Recently, a significant inverse correlation between postparacentesis changes in plasma renin activity and systemic vascular resistance has been demonstrated in these patients, suggesting that peripheral arterial vasodilatation could be responsible for this circulatory dysfunction, but the mechanisms by which tense ascites removal induces such changes are unknown
AIM—To investigate the role of a decrease in intra-abdominal pressure (IAP) in the development of early postparacentesis haemodynamic changes
METHODS—Eleven cirrhotic patients with tense ascites received a large volume paracentesis. A specially designed pneumatic girdle was used to compress the abdomen to avoid a decrease in IAP during ascites removal. Haemodynamic studies were performed before paracentesis, one hour after ascites flow stopped, and 30 minutes after pneumatic girdle deflation
RESULTS—When IAP was maintained at its original level, no haemodynamic changes were observed, despite large volume paracentesis. However, a significant decrease in systemic vascular resistance was seen immediately after pneumatic girdle deflation
CONCLUSIONS—Early haemodynamic changes after paracentesis are avoided if IAP is maintained at its original level. The abrupt decrease in IAP could be the trigger for the development of the initial haemodynamic changes that eventually produce postparacentesis circulatory dysfunction.

    Ascites often contributes to patient morbidity and discomfort. When refractory to medical management, it has been managed with repeated paracentesis, implantable ports for drainage, or diversion to the urinary bladder. Peritoneovenous shunt insertion has been a technique that was traditionally performed only by surgeons but is now within the realm of interventional radiologists. Its advantage is that protein-rich ascitic fluid is returned to the intravascular compartment. This retrospective study elaborates on the successes and problems encountered during shunt insertion in our first 13 patients. Two patients are well with a functioning shunt at 14 and 32 weeks. In 6 the shunt functioned until the patients' death from the underlying malignancy. Two required revision with variable success and in 2, shunt function could not be salvaged. There was one procedure-related mortality. Radiological insertion of these shunts is feasible and should be considered for selected patients. Options are available for assessment and salvaging of dysfunctional shunts.

    Refractory ascites (RA) is thought to complicate the postoperative course of 5-7% (Nishida et al. in Am J Transplant. 6: 140-149, 2006; Gotthardt et al. in Ann Transplant. 18: 378-383, 2013) of liver transplant recipients. RA after liver transplantation is often a frustrating diagnostic dilemma with few good management options unless an obvious mechanical factor is identified. Supportive therapies often fail until a treatable precipitating cause is identified and removed. We describe two patients who developed RA following liver transplantation for primary sclerosing cholangitis, and hepatitis C and alcoholic liver disease, respectively. The cause for RA was hyperkinetic portal hypertension secondary to splenomegaly in the first case and a pancreatic AVM in the 2nd case. After failure of other interventions, surgical splenectomy resulted in immediate and durable resolution of the previously intractable ascites. PMID:26017456

    Congenital chylous ascites (CCA) is a rare disease that results from maldevelopment of the intra-abdominal lymphatic system. Few cases have been described and no gold standard treatment has been defined so far. Octreotide, a somatostatin analogue, has been used for the treatment of CCA, but always after a failed conservative approach with fasting, total parenteral nutrition (TPN) or medium chain triglyceride (MCT) feeds. We report the case of a newborn with CCA treated by fasting, TPN and octreotide for a period of 15 days until the abdominal distension was successfully reduced at which point treatment was switched to an MCT formula. On day 25 the patient was breastfed and was discharged on day 33. No recurrence of chylous ascites was noted. Our experience highlights the successful treatment with TPN and octreotide as the first step for the conservative approach of CCA in a newborn, reducing the length of treatment and hospitalisation.

    The authors investigate the antiangiogenic and proapoptotic effects of mustard essential oil containing allyl isothiocyanate (AITC) and explore its mechanism of action on Ehrlich ascites tumor (EAT) cells. Swiss albino mice transplanted with EAT cells were used to study the effect of AITC. AITC was effective at a concentration of 10 mum as demonstrated by the inhibition of proliferation of EAT cells when compared with the normal HEK293 cells. It significantly reduced ascites secretion and tumor cell proliferation by about 80% and inhibited vascular endothelial growth factor expression in tumor-bearing mice in vivo. It also reduced vessel sprouting and exhibited potent antiangiogenic activity in the chorioallantoic membrane and cornea of the rat. AITC arrested the growth of EAT cells by inducing apoptosis and effectively arrested cell cycle progression at the G1 phase. The results clearly suggest that AITC inhibits tumor growth by both antiangiogenic and proapoptotic mechanisms.

    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.

    Sclerosing encapsulating peritonitis, also known as ‘Cocoon Syndrome’, is a rare cause of bowel obstruction. The condition might be congenital or acquired and has non-specific symptomatology. Abdominal pain occurs due to the limitation of intestinal motility or segment obstruction by a thick homogenous fibrotic mantle covering the intra-peritoneal organs. Altered peritoneal fluid dynamics result in persistent ascites. Leading pathogenic theories are not well defined, but genetic factors, retrograde trans-tubal flow of causative agents, peritoneal infections, medications and peritoneal invasive procedures are all thought to play a role. There are no specific diagnostic criteria and exact diagnosis is only confirmed during surgery when the investing thick fibrous folds covering the bowel loops are visualised. We present here a case that had been suspected to have an ovarian malignancy due to a huge abdominal heterogeneous mass and ascites on preoperative diagnostic workup, but had a final diagnosis of abdominal Cocoon Syndrome made during surgery.

  14. Pathogenesis of solute-free water retention in experimental ascitic cirrhosis: is vasopressin the only culprit?

    2016-01-01

    Catecholamines trigger proximal tubular fluid retention and reduce renal excretion of solute-free water. In advanced cirrhosis, non-osmotic hypersecretion of vasopressin (antidiuretic hormone or ADH) is considered the cause of dilutional hyponatraemia, but ADH V2 receptor antagonists are not beneficial in long-term treatment of ascites. To test the hypothesis that water retention in experimental ascitic cirrhosis might depend primarily on adrenergic hyper-function, hormonal status, renal function and tubular free-water reabsorption (TFWR) were assessed in six groups of rats with ascitic cirrhosis: rats with cirrhosis due to 13-week CCl4 (carbon tetrachloride) administration (group G1); cirrhotic rats receiving daily diuretics (0.5 mg/kg furosemide plus 2 mg/kg K(+)-canrenoate) from the 11th to the 13th week of CCl4 (G2), diuretics associated with guanfacine oral prodrug (α2A-adrenergic receptor agonist and sympatholytic agent) at 2 (G3), 7 (G4) or 10 (G5) mg/kg, or with SSP-004240F1 (V2 receptor antagonist) at 1 mg/kg (G6). Natriuresis was lower in G1 than in G2, G4 and G6 (all P<0.05). Guanfacine, added to diuretics (i.e. G3 compared with G2), reduced serum noradrenaline from 423±22 to 211±41 ng/l (P<0.05), plasma renin activity (PRA) from 35±8 to 9±2 ng/ml/h (P<0.05) and TFWR from 45±8 to 20±6 μl/min (P<0.01). TFWR correlated with plasma aldosterone (r=0.51, P<0.01) and urinary potassium excretion (r=0.90, P<0.001). In ascitic cirrhosis, reduced volaemia, use of diuretics (especially furosemide) and adrenergic hyper-function cause tubular retention of water. Suitable doses of sympatholytic agents are effective aquaretics. PMID:26519424

    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.

    Primary myelofibrosis (PMF) is a clonal hematopoietic stem cell disorder. It is characterized by bone marrow fibrosis, extramedullary hematopoiesis with hepatosplenomegaly and leukoerythroblastosis in the peripheral blood. The main clinical manifestations of PMF are anemia, bleeding, hepatosplenomegaly, fatigue, and fever. Here we report a rare case of PMF with anemia, small bowel obstruction and ascites due to extramedullary hematopoiesis and portal hypertension. The diagnosis was difficult to establish before surgery and the differential diagnosis is discussed. PMID:25206301

    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.

    Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs' syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL) in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs' syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices. PMID:23431489

    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

    We report successful anesthetic management of extended operation for peritoneal pseudomyxoma combined with massive ascites (16.5 l). A 66-year-old man (weight 76 kg) who could not keep a supine position due to massive ascites associated with peritoneal pseudomyxoma was scheduled for elective peritonectomy and extended surgery. With the patient in the semisitting position, we administered 3% sevoflurane to induce loss of consciousness while preserving spontaneous ventilation. We then performed crush induction with propofol and rocuronium after topical anesthesia to the tongue base. Tracheal intubation with the Macintosh laryngoscope was successful. During the operation, we aspirated about 16.5 l of ascites over 20 l normal saline irrigation. To maintain the body temperature, we performed both active and passive extracorporeal warming. The operation included not only total peritonectomy but also distal gastrectomy, right colon resection, splenectomy, and cholecystectomy. To perform effective postoperative analgesia, we placed two epidural catheters from the upper and lower thoracic epidural spaces. The patient was extubated 3 days after operation, and discharged uneventfully on the 18th postoperative day. PMID:27483656

    The pathogenetic role of ADH in determining hyponatremia in patients with liver cirrhosis is still much debated. Osmotic stimuli are not able to inhibit secretion of ADH in refractory ascites and under such conditions the reduction in effective plasma volume has been put forward as the main cause. Twenty patients with liver cirrhosis and refractory ascites were studied before and during extraction-concentration-reinfusion (ECR) of ascitic fluid by means of Rhodiascit. ADH, renin, aldosterone, blood and urine osmolarity, plasma and urinary concentration of sodium, potassium, chlorine, and the clearance of free water were evaluated. All patients presented high renin values (15.4 +/- 11.7 ng/ml), aldosterone (341 +/- 172 ng/ml), ADH (6.3 +/- 5.2 pg/ml). During ECR, a significant drop was observed in renin (p less than 0.001), aldosterone (p less than 0.001) urinary osmolarity (p less than 0.001) and an equality significant increase in diuresis (p less than 0.001), natriuria (p less than 0.005), kaliuria (p less than 0.001) while ADH presented an irregular course: in 11 cases it remained unchanged, in 3 it fell and in 6 it presented a constant increase. To conclude, data suggest that the diminished filtrate reaching the distal tubule constitutes the greatest cause of the inability to dilute urine in many patients with cirrhosis and that ADH is a permissive rather than a primary factor.

    Galactoxyloglucan polysaccharide (PST001), isolated from the seed kernels of Tamarindus indica (Ti), was used both as reducing and capping agent for the preparation of gold nanoparticles (PST-Gold) of 20 nm size. The present study evaluated the anticancer effects of the PST-Gold nanoparticles both in vitro and in vivo. The cytotoxicity was evaluated in the murine cancer cell lines, Dalton's lymphoma ascites (DLA) and Ehrlich's ascites carcinoma (EAC). Galactoxyloglucan-gold nanoparticles (PST-Gold) not only retained the anticancer effects of PST001, but also showed enhanced cytotoxicity via induction of apoptosis even at lower doses and lesser incubation times. In vivo antitumor activity was tested in DLA and EAC murine ascites and EAC solid-tumor syngeneic mouse models. PST-Gold nanoparticles reduced tumor burden and increased median survival and life span significantly in both tumor models compared to the controls. The PST-Gold nanoparticles were very effective as a chemopreventive agent, showing the best overall response when administered prior to tumor induction. In the case of solid tumors, intratumoral administration of the PST-Gold nanoparticles yielded significant results with regard to survival and increment in lifespan as compared to intraperitoneal mode of drug administration. Further studies in higher animal models and in patients at high-risk for recurrence are warranted to fully explore and develop the potential of PST-Gold nanoconjugates as a chemopreventive and therapeutic anti-cancer agent.

    Possibility of Pasteur effect in cancer cells in vivo was studied on mice with Ehrlich ascites carcinoma and rats with carcinoma of ovaries++. The experiments were run in two series. In the first series, all animals were saturated with oxygen through inhalation. In this series, part of the animals were given glucose subcutaneously. In the second series, all animals were given oxygen intraperitoneally and some of the animals with carcinoma of ovaries++ were given glucose subcutaneously. Values of inhibition of glycolytic activity in cancer cells under various experimental conditions were estimated through a calculated coefficient. Results of the experiment evidenced that inhalational saturation of animals with oxygen did not inhibit glycolysis of ascites cells in vivo while after intraperitoneal administration of oxygen, coefficient of inhibition of glycolytic activity in mice with Ehrlich ascites++ carcinoma after 45-65 min was 50-615, respectively. Experiments on rats showed that inhibition of glycolytic activity in rats can be revealed during simultaneous administration of oxygen intraperitoneally and of glucose subcutaneously. The authors reached the conclusion that under adequate supply of cancer cells with oxygen respiration can suppress glycolysis at the level of organism as well.

  6. Artificial ascites is feasible and effective for difficult-to-ablate hepatocellular carcinoma.

    2015-10-01

    Hepatocellular carcinoma (HCC) is the second leading cause of cancer death worldwide. Curative treatments for early-stage HCC include local ablation, hepatic resection, and liver transplant. Radiofrequency ablation (RFA) is a minimally invasive treatment and can be used in patients who have an increased risk of hepatic resection, including a liver reserve of Child-Pugh B status and suboptimal general condition. However, a difficult location of HCC can interfere with the performance of RFA because of a conspicuous lesion, poor electrode path, or increased risk of thermal injury to adjacent organs. Difficult locations include tumors abutting the diaphragm or near vital organs such as the gastrointestinal tract and gallbladder. Because artificial ascites can provide an improved sonic view and protects adjacent vital organs from thermal injury, it widens the indication of RFA in the treatment of HCC. The systemic review showed that the technique of artificial ascites has a high success rate (>90 %) without the clear appearance of severe adverse events such as intraperitoneal hemorrhage or gastrointestinal perforation. The risk of intraperitoneal seeding is not increased. In addition, the therapeutic effectiveness, such as the complete ablation rate or local tumor progression rate, remains satisfactory for difficult-to-ablate HCCs. In conclusion, RFA after infusion of artificial ascites is feasible and effective for difficult-to-ablate HCCs. However, because data on the local tumor progression rate, heat-sink effect, and intraperitoneal seeding are scarce, additional studies are required.

  7. Osteoprotegerin (OPG) protects ovarian cancer cells from TRAIL-induced apoptosis but does not contribute to malignant ascites-mediated attenuation of TRAIL-induced apoptosis

    PubMed Central

    2012-01-01

    Background Resistance to apoptosis is a major problem in ovarian cancer and correlates with poor prognosis. Osteoprotegerin (OPG) is a secreted factor in malignant ascites and acts as a decoy receptor for receptor activator of NF-κB ligand (RANKL) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). TRAIL promotes apoptosis in ovarian cancer cells. Ovarian cancer ascites attenuate TRAIL-induced apoptosis raising the possibility that OPG contained in ascites may abrogate the anti-tumor activity of TRAIL. Methods Determination of OPG levels in ascites was measured by ELISA. Effect of OPG on TRAIL-induced cell death was determined by XTT and colony forming assays in ovarian cancer cell lines and primary tumor cells. Apoptosis was assessed by ELISA. Results We found that recombinant OPG and malignant ascites attenuates TRAIL-induced cell death and apoptosis in a dose-dependent manner in ovarian cancer cell lines and primary ovarian tumor cells. OPG is present at high levels in the ascites of patients with ovarian cancer. We found a positive correlation between the levels of OPG in ascites and the ability of the ascites to attenuate TRAIL-induced cell death. The anti-apoptotic effect of ascites was not reversed by co-incubation with an OPG blocking antibody. Conclusions OPG and malignant ascites protect ovarian cancer cells from TRAIL-induced apoptosis. Although malignant ascites contain high levels of OPG, OPG is not a critical component that contributes to ascites-mediated attenuation of TRAIL-induced apoptosis. PMID:23153223

    Malignant ascites is a common complication in the late stages of epithelial ovarian cancer (EOC) that greatly diminishes the quality of life of patients. Malignant ascites is a known consequence of vascular dysfunction, but current approved treatments are not effective in preventing fluid accumulation. In this study, we investigated an alternative strategy of targeting macrophage functions to reverse the vascular pathology of malignant ascites using fluid from human patients and an immunocompetent murine model (ID8) of EOC that mirrors human disease by developing progressive vascular disorganization and leakiness culminating in massive ascites. We demonstrate that the macrophage content in ascites fluid from human patients and the ID8 model directly correlates with vascular permeability. To further substantiate macrophages' role in the pathogenesis of malignant ascites, we blocked macrophage function in ID8 mice using a colony-stimulating factor 1 receptor kinase inhibitor (GW2580). Administration of GW2580 in the late stages of disease resulted in reduced infiltration of protumorigenic (M2) macrophages and dramatically decreased ascites volume. Moreover, the disorganized peritoneal vasculature became normalized and sera from GW2580-treated ascites protected against endothelial permeability. Therefore, our findings suggest that macrophage-targeted treatment may be a promising strategy toward a safe and effective means to control malignant ascites of EOC.

    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.

    G. lucidum total triterpenes were assessed for its apoptosis-inducing and anti-tumour activities. The ability of the total triterpenes to induce apoptosis was evaluated in Dalton's lymphoma ascites (DLA) and Ehrlich's ascites carcinoma (EAC) cell lines. Total triterpenes were found to be highly cytotoxic to DLA and EAC cell lines with IC50 values 5 ± 0.32 and 7.9 ± 0.2 µg/ml respectively. Total triterpenes induced apoptosis in both cell lines which is evident from the DNA fragmentation assay. Anti-tumour activity was accessed using DLA induced solid and EAC induced ascites tumour models in Swiss albino mice. Administration of 10, 50 and 100 mg/kg b. wt. total triterpenes showed 11.86, 27.27 and 40.57% increase in life span of animals in ascites tumour model. Treatment with 10, 50 and 100 mg/kg b. wt. total triterpenes exhibited 76.86, 85.01 and 91.03% inhibition in tumour volume and 67.96, 72.38 and 77.90% inhibition in tumour weight respectively in the solid tumour model. The study reveals the significant dose-dependent anti-tumour activity of total triterpenes in both models. Total triterpenes were more active against the solid tumour than the ascites tumour. The anti-oxidant potential and ability to induce cell-specific apoptosis could be contributing to its anti-tumour activities. PMID:27188870

    Peritoneal carcinomatosis accompanied by malignant ascites is a major cause of death of advanced gastric cancer (GC). To comprehensively characterize the underlying genomic events involved in GC peritoneal carcinomatosis, we analyzed whole-exome sequences of normal gastric tissues, primary tumors, and malignant ascites from eight GC patients. We identified a unique mutational signature biased toward C-to-A substitutions in malignant ascites. In contrast, the patients who received treatment of adjuvant chemotherapy showed a high rate of C-to-T substitutions along with hypermutation in malignant ascites. Comparative analysis revealed several candidate mutations for GC peritoneal carcinomatosis: recurrent mutations in COL4A6, INTS2, and PTPN13; mutations in druggable genes including TEP1, PRKCD, BRAF, ERBB4, PIK3CA, HDAC9, FYN, FASN, BIRC2, FLT3, ROCK1, CD22, and PIK3C2B; and mutations in metastasis-associated genes including TNFSF12, L1CAM, DIAPH3, ROCK1, TGFBR1, MYO9B, NR4A1, and RHOA. Notably, gene ontology analysis revealed the significant enrichment of mutations in the Rho-ROCK signaling pathway-associated biological processes in malignant ascites. At least four of the eight patients acquired somatic mutations in the Rho-ROCK pathway components, suggesting the possible relevance of this pathway to GC peritoneal carcinomatosis. These results provide a genome-wide molecular understanding of GC peritoneal carcinomatosis and its clinical implications, thereby facilitating the development of effective therapeutics.

    Blood contamination, such as bloody ascites or hemorrhages during surgery, is a potential hazard for clinical application of fluorescence imaging. In order to overcome this problem, we investigate if fluorescence-lifetime imaging helps to overcome this problem. Samples were prepared at concentrations ranging 0.3–2.4 μm and mixed with 0–10% of blood. Fluorescence intensities and lifetimes of samples were measured using a time-domain fluorescence imager. Ovarian cancer SHIN3 cells overexpressing the D-galactose receptor were injected into the peritoneal cavity 2.5 weeks before the experiments. Galactosyl serum albumin-rhodamine green (GSA-RhodG), which bound to the D-galactose receptor and was internalized thereafter, was administered intraperitoneally to peritoneal ovarian cancer-bearing mice with various degrees of bloody ascites. In vitro study showed a linear correlation between fluorescence intensity and probe concentration (r2 > 0.99), whereas the fluorescence lifetime was consistent (range, 3.33 ± 0.15–3.75 ± 0.04 ns). By adding 10% of blood to samples, fluorescence intensities decreased to <1%, while fluorescence lifetimes were consistent. In vivo fluorescence lifetime of GSA-RhodG stained tumors was longer than the autofluorescence lifetime (threshold, 2.87 ns). Tumor lesions under hemorrhagic peritonitis were not depicted using fluorescence intensity imaging; however, fluorescence-lifetime imaging clearly detected tumor lesions by prolonged lifetimes. In conclusion, fluorescence-lifetime imaging with GSA-RhodG depicted ovarian cancer lesions, which were invisible in intensity images, in hemorrhagic ascites. PMID:24479901

  14. 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

    Bacterial translocation is currently considered the main pathogenic mechanism leading to spontaneous bacterial peritonitis in patients with advanced cirrhosis and ascites. However, to the authors' knowledge there is no information regarding the characteristics of this process in humans. The goals of the current study were to pursue partially identified bacterial DNA in blood (what the authors consider molecular evidence of bacterial translocation) through its relative quantification in a 72-hour study period by using real-time polymerase chain reaction (PCR). A consecutive series of 17 patients with advanced cirrhosis and culture-negative, nonneutrocytic ascites were studied. Therapeutic paracentesis was performed at the time of admission, and blood samples were obtained at baseline and every 8 hours in a 3-day period. Bacterial DNA was detected by a PCR-based method, relatively quantified by real-time PCR, and identified by automated nucleotide sequencing. Seven of 17 patients demonstrated the simultaneous presence of bacterial DNA in blood and ascitic fluid at the time of admission. After therapeutic paracentesis was performed, bacterial DNA persisted in the blood for a minimum of 24 hours, and was reported to last as long as 72 hours in some patients. In addition, different patterns of bacterial DNA appearance and clearance from the blood were identified. The nucleotide sequencing process demonstrated that bacteria detected in the first sample were identical to those noted in subsequent detections over time. In conclusion, bacterial translocation is a single-species, dynamic process that appears to develop in a subgroup of patients with advanced cirrhosis.

    Ascites syndrome in broiler chickens is defined as a condition associated with pulmonary hypertension leading to right heart failure, increased central venous pressure, passive congestion of the liver, and accumulations of serous fluids in body cavities. The syndrome is currently seen in fast-growing broiler chickens associated with an increase in the weight, volume, and area of the right ventricle of the heart. The ratio of the right ventricle weight to the total heart mass has been used to assess the consequences of increased blood pressure. The right ventricle area (RVA) can be quantified using image analysis technology. Hearts were removed from 719 male broilers at slaughter (42 d). All birds were visually scored for the incidence of ascites. A score of 0 or 1 represented slight hydropericardium, slight right heart hypertrophy, and slight edema. A score of 4 was assigned to birds with marked accumulation of ascitic fluid in one or more ceolomic cavities, pronounced dilation of the right heart, and prominent liver lesions. A cross-sectional image of each heart slice (a 4-mm-thick slice of the ventricles) was digitally recorded. Using image analysis software, the RVA, left ventricular area (LVA), and total heart area (HA) were determined. Because a slice of the heart was used in image analysis, the importance of maintaining the original shape was determined. Twenty hearts in five ranges of RVA size were scanned in four different positions, which have differing heart slice orientations and differing RVA shapes, for a comparison of positioning technique (placement) relating to the RVA. The shape of the heart slice for image analysis was observed not to be critical for the small RVA. For heart slices with large RVA values, it was found to be critical to analyze the heart slice in a standardized placement. PMID:10023748

    Medium chain triglyceride (MCT)-based diet, total parenteral nutrition (TPN) and repeated paracentesis are considered as supportive management for congenital chylous ascites (CCA). TPN is considered where therapy with oral MCT is poorly tolerated by the patient especially young infant with unstable hemodynamic. Surgery is recommended when medical therapy fails. Herein, we report a 2½-month-old infant with CCA, treated successfully with octreotide intravenous infusion after the initial failure to response to conventional conservative therapy with MCT-enriched formula and paracentesis.

    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.

    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.

    A 70-year-old man presented with abdominal distention and pain. A diagnosis of chylous ascites (CA) was made by abdominal paracentesis. Conservative treatment had failed to control CA; therefore, ultrasound-guided intranodal lymphangiography (UIL) with Lipiodol was performed. No obvious Lipiodol leakage was observed in the follow-up computed tomography; however, the persistent abdominal pain was significantly reduced within a day, and CA was resolved within 3 days. We present successful treatment of CA using UIL with Lipiodol. The combination of the technique of UIL and therapeutic lymphangiography with Lipiodol is a promising minimally invasive treatment option for CA.

    AIM: To investigate the procedure, feasibility and effects of laparoscope-assisted continuous circulatory hyperthermic intraperitoneal perfusion chemotherapy (CHIPC) in treatment of malignant ascites induced by peritoneal carcinomatosis from gastric cancers. METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscope-assisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5-fluorouracil (5-FU) and 200 mg oxaliplatin were added in the perfusion solution. The second and third sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5-FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450-600 mL/min and an inflow temperature of 43 ± 0.2°C. RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscope-assisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscope-assisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the follow-up, 13 patients died 2-9 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (50-90) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated

    At least one-third of patients with epithelial ovarian cancer (OC) present ascites at diagnosis and almost all have ascites at recurrence. The presence of ascites, which acts as a dynamic reservoir of active molecules and cellular components, correlates with the OC peritoneal metastasis and is associated with poor prognosis. Since epithelial-mesenchymal transition (EMT) is involved in different phases of OC progression, we have investigated the effect of the unique ascitic tumor microenvironment on the EMT status and the behavior of OC cells. The exposure of three OC cell lines to ascites leads to changes in cellular morphologies. Within ascites, OC cells harboring an initial intermediate epithelial phenotype are characterized by marked dislocation of epithelial markers (E-cadherin, ZO-1 staining) while OC cells initially harboring an intermediate mesenchymal phenotype strengthen their mesenchymal markers (N-cadherin, vimentin). Ascites differentially triggers a dissemination phenotype related to the initial cell features by either allowing the proliferation and the formation of spheroids and the extension of colonies for cells that present an initial epithelial intermediate phenotype, or favoring the migration of cells with a mesenchymal intermediate phenotype. In an ascitic microenvironment, a redeployment of αv integrins into cells was observed and the ascites-induced accentuation of the two different invasive phenotypes (i.e. spheroids formation or migration) was shown to involve αv integrins. Thus, ascites induces a shift toward an unstable intermediate state of the epithelial-mesenchymal spectrum and confers a more aggressive cell behavior that takes on a different pathway based on the initial epithelial-mesenchymal cell features.

    Chickens have been raised as food for human consumption for over 4000 years. Over this time they have been continuously selected for specific desirable characteristics by active selection of parents to produce birds which fit perceived needs. Despite this long history of selective breeding and improvements in rearing techniques, the efficiency with which broiler meat is produced has shown a remarkable leap in recent decades. Persistent selection for rapid growth, high feed utilisation efficiency and large cut yield has resulted in modern meat-type poultry lines with superior genetic potential with regard to productivity. However, mortality and the incidence of metabolic diseases has increased in parallel with growth rate. One such disease is broiler ascites syndrome, which has been shown to be closely associated with the fast growth and high meat yield resulting from intense selection and with modern rearing techniques. The review is focused on the historical background, pathogenesis, epidemiology and prevention of broiler ascites syndrome in modern broiler production. PMID:23628419

    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.

    A young woman received a diagnosis of abdominal, sporadic lymphangioleiomyomatosis (LAM) and multiple abdominal lymphangioleiomyomas and was referred for recurrent chylous ascites responding only to a fat-free diet. On admission, pulmonary function test (PFT) results showed a moderate reduction in the transfer factor for carbon monoxide with normal exercise performance. The serum vascular endothelial growth factor D (VEGF-D) level was 2,209 pg/mL. DNA sequences, amplified at loci kg8, D16S3395, D16S3024, D16S521, and D16S291 on chromosome 16p13.3, showed a loss of heterozygosity (LOH) only for kg8. Fat-free total parenteral nutrition in association with sirolimus (2 mg po daily) was initiated. Serum sirolimus levels were maintained at concentrations between 5 and 15 ng/mL. After 1 month, reintroduction of a low-fat oral feeding was achieved without recurrence of ascites. PFT results were stable. Interestingly, clinical improvement was associated with a reduction in the VEGF-D serum level (1,558 pg/mL). LOH at the kg8 biomarker in blood LAM cells was no longer detected.

    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

    We have examined the ultrastructure of mitochondria as it relates to energy metabolism in the intact cell. Oxidative phosphorylation was induced in ultrastructurally intact Ehrlich ascites tumor cells by rapidly generating intracellular adenosine diphosphate from endogenous adenosine triphosphate by the addition of 2-deoxyglucose. The occurrence of oxidative phosphorylation was ascertained indirectly by continuous and synchronous monitoring of respiratory rate, fluorescence of pyridine nucleotide, and 90° light-scattering. Oxidative phosphorylation was confirmed by direct enzymatic analysis of intracellular adenine nucleotides and by determination of intracellular inorganic orthophosphate. Microsamples of cells rapidly fixed for electron microscopy revealed that, in addition to oxidative phosphorylation, an orthodox → condensed ultrastructural transformation occurred in the mitochondria of all cells in less than 6 sec after the generation of adenosine diphosphate by 2-deoxyglucose. A 90° light-scattering increase, which also occurs at this time, showed a t ½ of only 25 sec which agreed temporally with a slower orthodox → maximally condensed mitochondrial transformation. Neither oxidative phosphorylation nor ultrastructural transformation could be initiated in mitochondria in intact cells by the intracellular generation of adenosine diphosphate in the presence of uncouplers of oxidative phosphorylation. Partial and complete inhibition of oxidative phosphorylation by oligomycin resulted in a positive relationship to partial and complete inhibition of 2-deoxyglucose-induced ultrastructural transformation in the mitochondria in these cells. The data presented reveal that an orthodox → condensed ultrastructural transformation is linked to induced oxidative phosphorylation in mitochondria in the intact ascites tumor cell. PMID:5111873

    1. Added Ca2+ inhibited lactate formation from sugar phosphates by intact Ehrlich ascites-tumour cells. Lactate formation from glucose by these cells was unaffected by added Ca2+. 2. The Ca2+ inhibition of lactate formation by intact cells occurred in the extracellular medium. 3. Intact ascites-tumour cells did not take up Ca2+ in vitro. 4. Glycolysis of sugar phosphates by cell extracts as well as pyruvate formation from 3-phosphoglycerate and phosphoenolpyruvate was inhibited by Ca2+. 5. It was concluded that Ca2+ inhibited the pyruvate-kinase (EC 2.7.1.40) reaction. Further, Ca2+ inhibition of pyruvate kinase could be correlated with the overall inhibition of glycolysis. 6. Concentrations of Ca2+ usually present in Krebs–Ringer buffers, inhibited glycolysis and pyruvate-kinase activity by approx. 50%. 7. The inhibition of glycolysis by added Ca2+ could be partially reversed by K+ and completely reversed by Mg2+ or by stoicheiometric amounts of EDTA. 8. The hypothesis is advanced that the inability of tumour cells to take up Ca2+ is a factor contributing towards their high rate of glycolysis. PMID:6007855

    A young woman received a diagnosis of abdominal, sporadic lymphangioleiomyomatosis (LAM) and multiple abdominal lymphangioleiomyomas and was referred for recurrent chylous ascites responding only to a fat-free diet. On admission, pulmonary function test (PFT) results showed a moderate reduction in the transfer factor for carbon monoxide with normal exercise performance. The serum vascular endothelial growth factor D (VEGF-D) level was 2,209 pg/mL. DNA sequences, amplified at loci kg8, D16S3395, D16S3024, D16S521, and D16S291 on chromosome 16p13.3, showed a loss of heterozygosity (LOH) only for kg8. Fat-free total parenteral nutrition in association with sirolimus (2 mg po daily) was initiated. Serum sirolimus levels were maintained at concentrations between 5 and 15 ng/mL. After 1 month, reintroduction of a low-fat oral feeding was achieved without recurrence of ascites. PFT results were stable.

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

    1980-03-25

    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.

    This paper describes the characterization of aconitate hydratase (EC 4.2.1.3) in cytoplasmic and mitochondrial extracts from Ehrlich ascites tumor cells carried by BALB/C mice. The results show a similar distribution of aconitate hydratase in both extracts, with specific activities much lower than those found in pig and mouse tissues. Mitochondrial aconitate hydratase shows a substrate inhibition by citrate with a Km similar to that found in cytoplasm (Km = 1.0 mM and 0.9 mM, respectively). Oxalacetate produces a mixed type of inhibition in both cytoplasmic and mitochondrial aconitate hydratases with different inhibition constants (Ki = 0.3 mM and 1.0 mM, respectively). Moreover, the specific activities of aconitate hydratase in both cytoplasm and mitochondria decrease when the tumor progresses in the peritoneum of BALB/C mice, as well as the percentage of aconitate hydratase activity in the presence of oxalacetate as the inhibitor. These results indicate that the activity and kinetics of aconitate hydratase are markedly altered by neoplastic transformation as occurs in Ehrlich ascites tumor cells. Since aconitate hydratase is not a key enzyme, these unexpected data are of interest in the study of cancer biochemistry. PMID:3179020

    Phorbol-12-myristate-13-acetate (PMA), calcium ionophore A23187 and platelet activating factor (PAF) stimulated the generation of oxygen free radicals (nitro-blue tetrazolium reduction) in Ehrlich ascites tumour (EAT) cells. PAF was effective at an optimal concentration of 4 μM, but was inhibited by BN 52021, a specific PAF antagonist. Lyso-PAF was ineffective. Inclusion of different lipids during incubation prior to the addition of PAF, resulted in the activation/inhibition of free radical generation. Among the phospholipids at a concentration of 50 μg/ml, the order of activation was phosphatidylserine > phosphatidylglycerol > phosphoinositides > phosphatidylinositol > phosphatidylethanolamine. Phosphatidylcholine was not effective, while sphingolipids were inhibitory. In addition, Ehrlich ascites tumour cells grown in mice under marginal vitamin A deficiency, showed an augmented production of free radicals compared to control cells. This was suppressed by exogenous addition of vitamin A or superoxide dismutase. These results suggest that membrane lipids and dietary factors like vitamin A probably function as physiological modulators in regulating the free radical generation. PMID:18475503

    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. PMID:27020875

    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.

    Studies suggest that prophylactic intra-abdominal drains are unnecessary for cadaveric liver transplantation using whole liver grafts because there is no benefit from drainage. However, no studies have investigated on the necessity of prophylactic drains after LDLT using split-liver grafts or reduced-liver grafts, which may present a high risk of post-transplant intra-abdominal infections. This retrospective study investigated whether the ascitic data on POD 5 after LDLT can predict intra-abdominal infections and on the post-transplant management of prophylactic drains. Between March 2008 and March 2013, 90 LDLTs were performed. We assessed the number of ascitic cells, biochemical examinations, and cultivation tests at POD1 and POD5. The incidence rates of post-transplant intra-abdominal infections were 24.4%. The multivariate analysis showed that left lobe and S2 monosegment grafts were a significant risk factor for intra-abdominal infections (p = 0.006). The patients with intra-abdominal infections had significantly higher acsitic LDH levels and the positive rate of ascitic culture at POD5 in comparison with patients without infections (p < 0.001 and p = 0.014, respectively). LDLT using left lobe and S2 monosegment grafts yields a high risk for post-transplant intra-abdominal infections, and ascitic LDH and cultivation tests at POD5 via prophylactic drains can predict intra-abdominal infections.

    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

    Adult granulosa cell tumors (AGCTs) presenting with massive ascites and elevated serum CA-125 levels have rarely been described in the literature. An ovarian mass, massive ascites, and elevated serum CA-125 levels in postmenopausal women generally suggest a malignant ovarian tumor, particularly advanced epithelial ovarian cancer. AGCT has low 18F-fluorodeoxyglucose uptake on positron emission tomography/computed tomography due to its low metabolic activity. In the present report, we describe a case of an AGCT with massive ascites, elevated serum CA-125 level, and low 18F-fluorodeoxyglucose uptake on positron emission tomography/computed tomography.

  1. Stress and morphine affect survival of rats challenged with a mammary ascites tumor (MAT 13762B).

    We have previously shown that exposure to inescapable footshock stress decreases survival of rats injected with a mammary ascites tumor (MAT 13762B). This increased vulnerability to the tumor challenge was prevented by an opiate antagonist, naltrexone, suggesting mediation by opioid peptides. Supporting this hypothesis, we now report that a high dose of an opiate agonist, morphine, also reduces survival of rats given the same tumor. This effect shows tolerance after 14 daily injections. The adverse effect of stress, however, did not show other signs of opioid involvement: it manifested neither tolerance with repeated stress exposures nor cross-tolerance in morphine-tolerant rats. Our recent findings that stress and morphine reduce natural killer cell cytotoxicity in a similar fashion suggest an immune mechanism that may explain the present results.

    Cytotoxicity of the two pesticides, thiram and endosulfan, have been studied in Ehrlich ascites tumor cells. Thiram cytotoxicity was much lower than that of endosulfan with LC(50) (1h exposure) of 4.02 and 1.12mM, respectively. The cytotoxic action of the pesticides on the cells were characterised by glutathione depletion, induction of reactive oxygen species (ROS). The cell death induced by the pesticides was of necrotic type as confirmed by lactate dehydrogenase (LDH) leakage. At non-cytotoxic concentration, thiram potentiated the cytotoxicity of endosulfan when cells were exposed to a mixture of both chemicals. The mechanisms involved in the potentiation of cytotoxicity include excessive glutathione depletion and induction ROS which were higher than the additive effects of individual chemicals. The study demonstrates the importance of pesticide interactions in toxicity risk assessment.

    Accumulation of a pure transudate abdominal effusion in the absence of significant hypoalbuminaemia is uncommon in dogs and is due to pre-sinusoidal portal hypertension. Reported causes of pre-sinusoidal portal hypertension vary, but suggest a reasonable prognosis. A retrospective analysis of 17 dogs that presented to our institution with ascites due to pre-sinusoidal portal hypertension identified idiopathic hepatic fibrosis or canine chronic hepatitis as the underlying cause in the majority of cases. Twelve (70.5%) dogs were 4 years of age or younger at time of presentation. Total serum protein was higher in dogs with chronic hepatitis than it was in dogs without inflammatory disease. The prognosis was generally poor and no histological, imaging or biochemical parameters were useful as prognostic indicators. Dogs died or were euthanased due to severe clinical signs associated with the portal hypertension and/or perceived poor prognosis.

    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.

    Hyperthermia (HPT) at 43 degrees C for 30 min increased the cytotoxic activity of doxorubicin against the growth of Ehrlich ascites carcinoma cells. There was more delay in tumor growth with 89% inhibition in the tumor volume and 90% increase in the survival of the tumor-bearing animals compared to control group. Combination of HPT with doxorubicin showed a more pronounced inhibitory effect on tumor content of DNA, RNA, protein, cholesterol, total lipid and acid phosphatase activity. HPT did not significantly affect the doxorubicin uptake into tumor cells, but it has some inhibitory effect on some vital components. Along with other results, our data suggest the benefit of using HPT to enhance the cytotoxic activity of doxorubicin with a consequent reduction of doxorubicin dose and hence a decrease of its serious side effects.

Titre ratios were calculated using the heterologous and homologous titres. Cross-CF reactions revealed wider antigenic variations among viruses than Cross-HI reactions. There was no significant antigenic variation between WSL, POT and YF viruses using either of those methods. However, definite differences in antigenicity were observed between them and UGS, BAN and ZK viruses. There were no significant differences between UGS, BAN and ZK or between DEN-1 and DEN-2. The serological relationship among flaviviruses is important in establishing diagnosis and epidemiology of these infections in Africa.

    Intratumoral injection of I-125 iododeoxyuridine (IUdR), saline solution, and oil suspension was investigated using Ehrlich ascites tumors in the thighs of mice. The oil suspension was more effective in tumor growth delay than was the saline solution. Single injection of the oil suspension at the dose of 12.5 microCi resulted in 21.5 days growth delay, whereas 50 microCi of the saline solution resulted in 11.5 days growth delay relative to control growth delay. At 40 days after treatment, higher radioactivities were observed in the tumor and the skin of the mice treated with the oil suspension, which represented the prolongation of I-125 IUdR oil suspension within the tumor. No normal tissue toxicities were observed.

    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

    The gamma interferon (gamma-IFN) concentration and the adenosine deaminase (ADA) activity were evaluated in 30 patients with tuberculous peritonitis, 21 patients with ascites due to a malignant disorder, and 41 patients with cirrhosis. The gamma-IFN concentrations were significantly higher (p < 0.0001) in tuberculous peritonitis patients (mean: 6.70 U/ml) than in the malignant (mean: 3.10 U/ml) and cirrhotic (mean: 3.08 U/ml) groups. Use of a cut off value of > or = 3.2 U/ml gave the assay a sensitivity of 93% (25 of 27), a specificity of 98% (54 of 55), positive (P+) and negative (P-) predictive values of 96% and a test accuracy of 96%. The ADA activity was significantly (p < 0.0001) higher in the tuberculous peritonitis group (mean: 101.84 U/l) than in the control groups (cirrhosis (mean: 13.49 U/l) and malignancy (mean: 19.35 U/l)). A cut off value of > 30 U/l gave the ADA test a sensitivity of 93% (26 of 28) a specificity of 96% (51 of 53), a (P+) value of 93%, a (P-) value of 96%, and a test accuracy of 95%. There was a significant (p < 0.0001) correlation (r = 0.72) between ADA activity and gamma-IFN values in patients with tuberculous peritonitis. These results show that a high concentration of gamma-IFN in ascitic fluid is as valuable as the ADA activity in the diagnosis of tuberculous peritonitis. Both are rapid non-invasive diagnostic tests for tuberculous peritonitis. PMID:7698702

    The current pathogenic theory of spontaneous bacterial peritonitis (SBP) in patients with cirrhosis and ascites suggests that repeated episodes of bacterial translocation (BT) from intestinal lumen to mesenteric lymph nodes followed by systemic seeding are the key steps for the final development of infectious events. However, most of the episodes of systemic bacterial circulation remain undetected. Therefore, we investigated the hypothetical presence of bacteria in blood and/or ascitic fluid (AF) from patients with cirrhosis and sterile (culture negative) AF by means of bacterial DNA (bactDNA) detection and identification. Twenty-eight consecutively admitted patients with cirrhosis and presence of AF were included in the study. BactDNA was detected using a polymerase chain reaction (PCR)-based method. The corresponding bacteria were identified by nucleotide sequencing of purified PCR products. BactDNA was detected simultaneously in blood and AF in 9 patients (32.1%). DNA sequencing allowed the identification of Escherichia coli (n = 7) and Staphylococcus aureus (n = 2). In all cases, the similarity between the sequence found in AF and blood indicated that the bactDNA present in both locations originated from a single clone (single translocation event). Child-Pugh score and basic hemodynamic, clinical, endoscopic, and biochemical characteristics were similar among patients with or without the presence of bactDNA. In conclusion, we have detected bactDNA in serum and AF in 32% of all patients studied, and this likely represents single clone episodes of translocation and systemic seeding. E. coli is the most frequently identified bacteria.

    Epithelial-mesenchymal transition (EMT) serves as a key mechanism driving tumor cell migration, invasion, and metastasis in many carcinomas. Transforming growth factor-beta (TGFβ) signaling is implicated in several steps during cancer pathogenesis and acts as a classical inducer of EMT. Since epithelial ovarian cancer (EOC) cells have the potential to switch between epithelial and mesenchymal states during metastasis, we predicted that modulation of TGFβ signaling would significantly impact EMT and the malignant potential of EOC spheroid cells. Ovarian cancer patient ascites-derived cells naturally underwent an EMT response when aggregating into spheroids, and this was reversed upon spheroid re-attachment to a substratum. CDH1/E-cadherin expression was markedly reduced in spheroids compared with adherent cells, in concert with an up-regulation of several transcriptional repressors, i.e., SNAI1/Snail, TWIST1/2, and ZEB2. Treatment of EOC spheroids with the TGFβ type I receptor inhibitor, SB-431542, potently blocked the endogenous activation of EMT in spheroids. Furthermore, treatment of spheroids with SB-431542 upon re-attachment enhanced the epithelial phenotype of dispersing cells and significantly decreased cell motility and Transwell migration. Spheroid formation was significantly compromised by exposure to SB-431542 that correlated with a reduction in cell viability particularly in combination with carboplatin treatment. Thus, our findings are the first to demonstrate that intact TGFβ signaling is required to control EMT in EOC ascites-derived cell spheroids, and it promotes the malignant characteristics of these structures. As such, we show the therapeutic potential for targeted inhibition of this pathway in ovarian cancer patients with late-stage disease. PMID:26647384

    A method is described for obtaining highly purified lysosomes from Ehrlich ascites tumo cells grown in mice injected with Triton WR-1339. 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.

    Eight endogenous G1 inhibitors of the proliferation of JB-1 ascites tumor cells have been isolated and characterized. The activity of the inhibitors has been analyzed on synchronized JB-1 (murine plasmacytoma) and L1A2 (murine sarcoma) cells in vitro using flow cytometry. The purified inhibitors have been tested for in vivo activity on partially synchronized JB-1 and L1A2 ascites tumors in situ. Four of the inhibitors exhibited a high degree of cell specificity (chalone-like inhibitors) and were chemically related, whereas the other four showed no cell specificity. In most extractions, the amount of cell-specific activity is more than 50% of the total G1-inhibitory activity. Most of the inhibitors are low-molecular-weight peptides and glycopeptides.

    A method is described which leads to the production of large amounts of ascites containing antitumor antibody in small numbers of mice. The antibody was then used to identify and characterize tumor-associated antigens on an ultraviolet light-induced murine skin fibrosarcoma. The antibody showed specific complement-dependent cytotoxicity to the homologous tumor and to an allogeneic tumor line which displayed a glycoprotein viral determinant with a molecular weight of 70,000 on its surface. Absorption of the immune ascites with other tumor cell lines removed the cytotoxicity in relation to the presence of the glycoprotein. Isolation of the tumor cell surface components binding antibody revealed two components with molecular weights of approximately 70,000 and 60,000. The Mr 70,000 component was identified as viral gp70 by peptide mapping.

    The course of hepatic cirrhosis involves alterations to the sodium-water balance, the aetiopathogenetic causes of which are still not entirely known. At first major importance was assigned to the role of secondary hyperaldosteronism which develops during the ascitic phase. This was subsequently recognised to have only a permissive rather than determinant function. Changes in the renin-angiotensin-aldosterone (RAA) system and variations in hydrosaline balance as the extracellular volume (ECV) expands during the reinfusion of concentrated ascitic fluid have been studied. The data reported show that ECV expansion causes increased diuresis, natriuresis and osmolar clearance. The RAA system is suppressed and at the same time kaliuresis increases. The latter factor points up the role played by increased solute flow to the distal tube in the diuretico-metabolic response, where aldosterone plays a purely permissive part. PMID:6675585

    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

    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.

    The case is about a young female who delivered twins by caesarean section (CS). On the 4th postoperative day, she presented with ascites which was resistant to empirical antibiotic and diuretic treatment. The woman was affected by Turner syndrome (TS); she had a medical background of chronic use of hormonal medication since puberty and conceived through ART- (assisted reproduction techniques-) IVF-oocyte donation. It is important to exhibit high suspicion for clot formation in the hepatic vasculature during the puerperium, especially in the case of history of chronic hormone treatment. Ascites albumin gradient and Doppler values lead to the diagnosis of thrombosis and the administration of high doses of anticoagulants is considered to be fundamental. PMID:26579320

    Small interfering RNA (siRNA) offers a great potential for the treatment of various diseases and disorders. Nevertheless, inefficient in vivo siRNA delivery hampers its translation into the clinic. While numerous successful in vitro siRNA delivery stories exist in reduced-protein conditions, most studies so far overlook the influence of the biological fluids present in the in vivo environment. In this study, we compared the transfection efficiency of liposomal formulations in Opti-MEM (low protein content, routinely used for in vitro screening) and human undiluted ascites fluid obtained from a peritoneal carcinomatosis patient (high protein content, representing the in vivo situation). In Opti-MEM, all formulations are biologically active. In ascites fluid, however, the biological activity of all lipoplexes is lost except for lipofectamine RNAiMAX. The drop in transfection efficiency was not correlated to the physicochemical properties of the nanoparticles, such as premature siRNA release and aggregation of the nanoparticles in the human ascites fluid. Remarkably, however, all of the formulations except for lipofectamine RNAiMAX lost their ability to be taken up by cells following incubation in ascites fluid. To take into account the possible effects of a protein corona formed around the nanoparticles, we recommend always using undiluted biological fluids for the in vitro optimization of nanosized siRNA formulations next to conventional screening in low-protein content media. This should tighten the gap between in vitro and in vivo performance of nanoparticles and ensure the optimal selection of nanoparticles for further in vivo studies.

    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. PMID:15109050

    In most experimental ascites tumors the growth rate decreases with increasing age and cell number. This decrease is caused by a prolongation of the cell cycle and an increasing accumulation of noncycling cells in resting (or quiescent) G1 and G2 compartments. In cell-free ascitic fluid from the JB-1 ascites tumor in the plateau phase of growth, low molecular weight substances have been found which reversibly and specifically arrest JB-1 cells in G1 and G2. In order to characterize the JB-1 G1 inhibitor we have investigated the effect of ion exchangers and polyions on the activity of this inhibitor assayed in vitro by means of a partially synchronized JB-1 cell population analyzed by flow microfluorometry. The results indicate that polyanions and cation exchangers (immobilized polyanions) bind and abolish the G1-inhibitory activity. From this it is suggested that the G1 inhibitor is of a basic or polycationic nature. Since anion exchangers (immobilized polycations) are without effect on this activity it was surprising to find that polycations also neutralize the activity. The results indicate that this occurs by blocking an anionic G2-inhibitor receptor on the cell, thus preventing the polycationic G1 inhibitor from being bound to this receptor.

    L’ascite maligna rappresenta il quadro avanzato di anormale accumulo di liquido intraperitoneale in pazienti con carcinosi peritoneale. Questa condizione clinica può rappresentare la condizione terminale di questa patologia a pessima prognosi inficiando inoltre la qualità di vita dei pazienti. Le opzioni terapeutiche includono differenti procedure che hanno tuttavia una limitata efficacia e alcune criticità; diuretici, paracentesi, shunt veno-peritoneali, inibitori delle metallo proteasi, immunomodulatori e agenti biologici rappresentano alcuni esempi di queste procedure. Nessuno di questi approcci terapeutici rappresenta a oggi lo standard of care per questa patologia data la scarsa efficienza e l’alto grado di effetti collaterali. L’introduzione della chirurgia citoriduttiva e della chemio terapia ipertermica intraperitoneale sembra essere un approccio terapeutico valido nel trattamento dell’ascite maligna refrattaria, introdotto nelle ultime due decadi e che tutt’ora necessita di validazione scientifica. In questo lavoro condividiamo la nostra esperienza di tre casi affetti da ascite maligna refrattaria trattati con HIPEC; facciamo inoltre una revisione della letteratura.

    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

    Curcumin, the active ingredient from the spice turmeric (Curcuma longa Linn), is a potent antioxidant and anti-inflammatory agent. It has been recently demonstrated to possess discrete chemopreventive activities. However, the molecular mechanisms underlying such anticancer properties of curcumin still remain unrealized, although it has been postulated that induction of apoptosis in cancer cells might be a probable explanation. In the current study, curcumin was found to decrease the Ehrlich's ascites carcinoma (EAC) cell number by the induction of apoptosis in the tumor cells as evident from flow-cytometric analysis of cell cycle phase distribution of nuclear DNA and oligonucleosomal fragmentation. Probing further into the molecular signals leading to apoptosis of EAC cells, we observed that curcumin is causing tumor cell death by the up-regulation of the proto-oncoprotein Bax, release of cytochrome c from the mitochondria, and activation of caspase-3. The status of Bcl-2 remains unchanged in EAC, which would signify that curcumin is bypassing the Bcl-2 checkpoint and overriding its protective effect on apoptosis. PMID:11676493

    In vivo studies of Ehrlich ascites tumor cells during the first 5 days of growth in peritoneal cavities of mice consisted of the following: 1. Determination of growth curves by direct enumeration of cells. 2. Estimation of the duration of each phase of the mitotic cycle based on incidence of cells in different phases. 3. Radioautographic studies to determine the proportion of cells in different phases of the mitotic cycle that incorporate tritiated thymidine during a single brief exposure to this precursor of DNA. 4. Estimation of the rate of incorporation of tritiated thymidine at different times during the period of DNA synthesis by comparison of mean grain counts over nuclei in radioautographs at different times following exposure to tritiated thymidine. The assumptions underlying these experiments and our observations concerning the duration of the period of DNA synthesis and its relation to the mitotic cycle are discussed. It is concluded that DNA synthesis is continuous, occupying a period of 8.5 hours during the interphase and that the average rate of synthesis is approximately constant. PMID:13819420

    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.

    We investigated antitumor, genotoxic, chemopreventive, and immunostimulative effects of local chemoimmunotherapy and hyperthermal intraperitoneal chemotherapy (HIPEC) in a mouse-bearing Ehrlich ascites tumor (EAT). Mice were treated with water-soluble derivative of propolis (WSDP) at a dose of 50 mg kg(-1) , 7 and 3 days before implantation of EAT cells, whereas cisplatin (5 or 10 mg kg(-1) ) was injected 3 days after implantation of EAT cells at 37°C and 43°C. The following variables were analyzed: the total number of cells, differential count of the cells present in the peritoneal cavity, functional activity of macrophages, comet assay, and micronucleus assay. The combination of WSDP + CIS 5 mg kg(-1) at 37°C resulted in tumor growth inhibition and increased the survival of mice by additional 115.25%. WSDP with HIPEC increased the survival of mice by additional 160.3% as compared with HIPEC. WSDP reduced cisplatin toxic and genotoxic effect to normal cells without affecting cisplatin cytotoxicity on EAT cells. In addition, WSDP with HIPEC increased the cytotoxic actions of macrophages to tumor cells. Water-soluble derivative of propolis increases macrophage activity and sensitivity of tumor cells to HIPEC and reduces cisplatin toxicity to normal cells.

    Chronic iron overload associated with hereditary hemochromatosis or repeated red cell transfusions is known to cause cardiac failure. Cardiac arrhythmias have been incidentally noted in patients with iron overload, but they are often dismissed as being related to comorbid conditions. Studies with anesthetized iron-loaded gerbils using short recordings suggest a role for iron in the development of arrhythmias. Our goal was to characterize iron-induced arrhythmias in the chronically instrumented, untethered, telemetered gerbil. Electrocardiograms were recorded for 10 s every 30 min for approximately 6 months in iron-loaded (n=23) and control (n=8) gerbils. All gerbils in both groups showed evidence of frequent sinus arrhythmia. There was no difference in heart rate, electrocardiographic parameters, or number of arrhythmias per minute between groups. Gerbils rarely showed significant arrhythmias. Body weight and heart weight were not significantly different between groups, whereas liver weight increased with increasing iron dose in the treated group. Cardiac and hepatic iron concentrations were significantly increased in iron-loaded gerbils. Eight of 14 gerbils loaded to 6.2 g/kg body weight developed ascites. We conclude that an iron load sufficient to cause clinical liver disease does not cause cardiac arrhythmias in the gerbil model of iron overload.

    Intracellular potentials were measured, using a piezoelectric electromechanical transducer to impale Ehrlich ascites tumor cells with capillary microelectrodes. In sodium Ringer's, the potential immediately after the penetration was -24±7 mV, and decayed to a stable value of about -8 mV within a few msec. The peak potentials disappeared in potassium Ringer's and reappeared immediately after resuspension in sodium. Ringer's, whereas the stable potentials were only slightly influenced by the change of medium. The peak potential is in good agreement with the Nernst potential for chloride. This is also the case when cell sodium and potassium have been changed by addition of ouabain. It is concluded that the peak potentials represent the membrane potential of the unperturbed cell, and that chloride is in electrochemical equilibrium across the cell membrane.The membrane potential of about -11 mV previously reported corresponds to the stable potential in this study, and is considered as a junction potential between damaged cells and their environment. Similar potential differences were recorded between a homogenate of cells and Ringer's.The apparent membrane resistance of Ehrlich cells was about 70 Ωcm(2). This is two orders of magnitude less than the value calculated from(36)Cl fluxes, and may, in part, represent a leak in the cell membrane.For comparison, the influence of an eventual leak on measurements in red cells and mitochondria is discussed.

    Cape aloe (Aloe ferox Miller) has been a herb well known for its cathartic properties and has also been used popularly as a health drink (juice, tea and tonic) in the United States and in Europe. Cape aloe extract also has been reported to possess several pharmacological effects, such as anti-inflammatory, anti-bacterial, anti-fungal and protective effect against liver injury. However, the investigations on an anti-tumor activity in cape aloe extract are very few and subsequent mechanisms have not been well elucidated. In this study, we examined the effect of the selective growth inhibitory activity of cape aloe extract and found that the cape aloe extract, especially the dichloromethane (CH(2)Cl(2)) extract, caused a dose-dependent growth inhibitory effect in Ehrlich ascites tumor cells (EATC), but not in mouse embryo fibroblast (NIH3T3) cells, which was used as a normal cell model. Furthermore, the CH(2)Cl(2) extract caused an accumulation of cells in the G1 phase and a decrease of cells in the S and G2/M phase of the cell cycle and inhibited DNA synthesis in a dose-dependent manner. In addition, other results suggest that cell cycle arrest and inhibition of proliferation in EATC by the CH(2)Cl(2 )extract are associated with decreased retinoblastoma protein (Rb) phosphorylation.

    Background. Treatment options are limited for patients with refractory cirrhotic ascites (RCA). As such, we assessed the safety and effectiveness of the PleurX catheter for RCA. Methods. A retrospective analysis was performed on all patients with RCA who have undergone insertion of the PleurX catheter between 2007 and 2014 at our clinic. Results. Thirty-three patients with RCA were included in the study; 4 patients were lost to follow-up. All patients were still symptomatic despite bimonthly large volume paracentesis and were not candidates for TIPS or PV shunt. Technical success was achieved in 100% of patients. The median duration the catheter remained in situ was 117.5 days, with 95% CI of 48-182 days. Drain patency was maintained in 90% of patients. Microorganisms consistent with spontaneous bacterial peritonitis (SBP) from a catheter source were isolated in 38% of patients. The median time to infection was 105 days, with 95% CI of 34-233 days. All patients were treated for SBP successfully with antibiotics. Conclusion. Use of the PleurX catheter for the management of RCA carries a high risk for infection when the catheter remains in situ for more than 3 months but has an excellent patency rate and did not result in significant renal injury.

    Krebs II ascite cells suspended in Eagle medium were incubated at 37 C for up to 6 hr in the presence of (TH) glycerol or (TSP) orthophosphate. After extraction, their lipids were treated with guinea pig phospholipase A1 under conditions where all diacyl-phospholipids (diacyl-PL) became hydrolyzed with 55% recovery of lyso-PL. Using a bidimensional thin layer chromatography (TLC) involving exposure to HCl fumes between the two runs, it then became possible to determine at once the specific radioactivity of the three subclasses present in choline glycerophospholipids (CGP) and ethanolamineglycerophospholipids (EGP). Compared to diacyl-PL, a lower de novo synthesis of ether subclasses was evidenced in both CGP and EGP by (TH) glycerol incorporation. Although the same profile was obtained for CGP with (TSP) orthophosphate, the three EGP subclasses displayed in this case the same specific radioactivity. These data indicate a higher turnover rate of the polar head group of ether-EGP compared to either-CGP. The simple methodology used in the present study might thus prove helpful in developing enzymatic studies dealing with the mechanism of this accelerated renewal.

    Objective To find out the effective anticancer drugs from bacterial products, petroleum ether extract of Corynebacterium xerosis. Methods Antiproliferative activity of the metabolite has been measured by monitoring the parameters like tumor weight measurement, tumor cell growth inhibition in mice and survival time of tumor bearing mice, etc. Hepatoprotective effect of the metabolites was determined by observing biochemical, hematological parameters. Results It has been found that the petroleum ether extract bacterial metabolite significantly decrease cell growth (78.58%; P<0.01), tumor weight (36.04 %; P<0.01) and increase the life span of tumor bearing mice (69.23%; P<0.01) at dose 100 mg/kg (i.p.) in comparison to those of untreated Ehrlich ascites carcinoma (EAC) bearing mice. The metabolite also alters the depleted hematological parameters like red blood cell, white blood cell, hemoglobin (Hb%), etc. towards normal in tumor bearing mice. Metabolite show no adverse effect on liver functions regarding blood glucose, serum alkaline phosphatases, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase activity and serum billirubin, etc. in normal mice. Histopathological observation of these mice organ does not show any toxic effect on cellular structure. But in the case of EAC bearing untreated mice these hematological and biochemical parameters deteriorate extremely with time whereas petroleum ether extract bacterial metabolite receiving EAC bearing mice nullified the toxicity induced by EAC cells. Conclusion Study results reveal that metabolite possesses significant antiproliferative and hepatoprotective effect against EAC cells. PMID:25183099

    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.

    A case of benign retroperitoneal cystic teratoma in a 62-year-old female is reported. The patient was admitted to our hospital for the purpose of extensive examination of a left abdominal mass. Radiological examinations including CT scanning revealed a large retroperitoneal mass arising in the left upper quadrant superior to the left kidney, containing cystic areas. The mass was removed by the thoracoabdominal approach under the diagnosis of cystic teratoma or liposarcoma. The margin of the mass was well demarcated and completely separated from other adjacent structures. Histological examination confirmed the diagnosis of benign cystic teratoma. From the 6th postoperative day, the discharge from a drainage tube, placed in the left retroperitoneal space, increased gradually and the discharge fluid became lipemic. The amount of daily discharge had a peak of approximately 400 ml on the 15th postoperative day. Total parenteral hyperalimentation was started on the 17th postoperative day under a diagnosis of chylous ascites. The amount of the discharge decreased and the drainage tube was removed on the 21st postoperative day.

    Streblus asper Lour (Moraceae), commonly known as Siamee Rough Brush in English is widely distributed in subtropical Asia and traditionally used for several medicinal purposes. In the present study, the ethyl acetate fraction of the methanol extract from Streblus asper bark (EASA) was evaluated for antitumor effect against Dalton's ascitic lymphoma (DAL) in Swiss albino mice. Twenty-four hours after intraperitoneal inoculation of DAL cells in mice, EASA was administered intraperitoneally at 200 and 400 mg/kg body weight for 9 consecutive days. On the 10th day, half of the mice were sacrificed to determine the tumor growth parameters, and the rest were kept alive for survival assessment. Hematological, serum biochemical and tissue (liver, kidney) antioxidant profiles were also determined. EASA exhibited significant and dose dependent decrease in tumor growth parameters and increased survival of DAL bearing animals. EASA significantly and dose-dependently normalized the altered hematological, serum biochemical and tissue antioxidant parameters as compared with the DAL control mice. From the present study it may be concluded that S. asper bark possesses remarkable antitumor efficacy mediated by amelioration of oxidative stress by multiple mechanisms. PMID:27486371

    A 6-year-old Nubian doe was evaluated because of slowly progressive abdominal enlargement of 1 month's duration. Five days prior to examination at our hospital, the doe was examined by a local veterinarian. False pregnancy was suspected, and 10 mg of prostaglandin F2 alpha was injected IM. Abdominal distention did not decrease, and the doe did not develop a vaginal discharge. An additional 10 mg of prostaglandin and 24 mg of dexamethasone were injected IM, about 80 hours after the first injection, again without any apparent effect. On arrival at our hospital, the doe was in sternal recumbency and was too weak to stand unassisted. Its abdomen was distended. The body of the uterus and part of 1 uterine horn could be examined by means of transrectal ultrasonography, both appeared normal. The doe was admitted to the hospital, but its condition worsened, and it died during the night. Postmortem examination revealed approximately 30 L of clear, pale, straw-colored fluid in the peritoneal cavity. The caudal pole of the left ovary contained an indistinct, firm, slightly raised, gray-tan mass. The final diagnosis was mucinous adenocarcinoma of the ovary metastatic to the partietal peritoneum, pericardium, and lungs. In adult female goats with bilateral abdominal distention, hydrometra associated with false pregnancy should always be considered; however, if there is no response to prostaglandin administration, distention is more likely to be a result of ascites.

  1. Risk factor analysis for massive lymphatic ascites after laparoscopic retroperitonal lymphadenectomy in gynecologic cancers and treatment using intranodal lymphangiography with glue embolization

    2016-01-01

    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.

    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

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

    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).

  5. Na+,Cl- cotransport in Ehrlich ascites tumor cells activated during volume regulation (regulatory volume increase).

    Ehrlich ascites cells were preincubated in hypotonic medium with subsequent restoration of tonicity. After the initial osmotic shrinkage the cells recovered their volume within 5 min with an associated KCl uptake. The volume recovery was inhibited when NO-3 was substituted for Cl-, and when Na+ was replaced by K+, or by choline (at 5 mM external K+). The volume recovery was strongly inhibited by furosemide and bumetanide, but essentially unaffected by DIDS. The net uptake of Cl- was much larger than the value predicted from the conductive Cl- permeability. The undirectional 36Cl flux, which was insensitive to bumetanide under steady-state conditions, was substantially increased during regulatory volume increase, and showed a large bumetanide-sensitive component. During volume recovery the Cl- flux ratio (influx/efflux) for the bumetanide-sensitive component was estimated at 1.85, compatible with a coupled uptake of Na+ and Cl-, or with an uptake via a K+,Na+,2Cl- cotransport system. The latter possibility is unlikely, however, because a net uptake of KCl was found even at low external K+, and because no K+ uptake was found in ouabain-poisoned cells. In the presence of ouabain a bumetanide-sensitive uptake during volume recovery of Na+ and Cl- in nearly equimolar amounts was demonstrated. It is proposed that the primary process during the regulatory volume increase is an activation of an otherwise quiescent, bumetanide-sensitive Na+,Cl- cotransport system with subsequent replacement of Na+ by K+ via the Na+/K+ pump, stimulated by the Na+ influx through the Na+,Cl- cotransport system.

    Objective: Anthocephalus cadamba (Roxb.) Miq. (Family: Rubiaceae), a folk medicine commonly known as “Kadam” in Bengali, has been used for the treatment of tumor. The methanolic extract of A. cadamba (MEAC) showing antitumor activity on Ehrlich ascites carcinoma (EAC) cells treated mice was already reported. This study was designed to study the apoptosis-inducing property of MEAC and its mechanism in EAC cells in mice. Materials and Methods: Apoptogenic morphology was determined by fluorescent DNA-binding double staining method using dyes acridine orange (AO)/ethidium bromide (EB). Comet assay was estimated to check the DNA damage. Flow cytometry (fluorescence-activated cell sorting [FACS]) was used to detect the apoptotic rate quantitatively by double labeling techniques using annexin V FITC/propidium iodide staining. Apoptotic protein expression was done using Western blotting assay method. Statistical Analysis: Results are expressed as mean ± standard deviation. Statistical analysis was performed using ANOVA followed by Dunnett's post hoc test of GraphPad Prism software. *P < 0.05, **P < 0.01 and ***P < 0.001 were considered statistically significant. Results: Apoptosis-inducing effect of MEAC on EAC cells was confirmed from AO/EB staining and FACS analysis. MEAC treatment showed dose-dependent induction of DNA damage. Apoptosis was induced by increasing the expression of multiple downstream factors such as pro-apoptotic protein p53 and p21 in EAC. Bax was up-regulated and anti-apoptotic protein Bcl-2 was down-regulated resulting in decrease of the Bcl-2/Bax ratio by MEAC treatment. Conclusion: Experimental results revealed that MEAC induces apoptosis by modulating the expression of some pro-apoptotic and anti-apoptotic proteins in EAC and thus exerts its anti-tumor activity.

    1. 5′-Nucleotidase activity was obtained in a soluble form after treatment of a particulate fraction from Ehrlich ascites-tumour cells with deoxycholate. The relative rates of hydrolysis of 6-thioinosine 5′-phosphate, UMP, AMP, CMP, GMP, IMP, xanthosine monophosphate, thymidine monophosphate and 2′,3′-AMP were 180, 129, 100, 93, 83, 79, 46, 41 and 3 respectively. 2. Values found for the Michaelis constant were: AMP, 67±12μm; IMP, 111±8μm; GMP, 93μm. 3. ATP and thymidine triphosphate were competitive inhibitors of AMP hydrolysis (inhibitor constants 0·4 and 4·8μm respectively); UTP, GTP and CTP were mixed competitive and non-competitive inhibitors. Thymidine triphosphate was a competitive inhibitor of IMP hydrolysis (inhibitor constant 14·4μm) and ATP, UTP and GTP showed mixed competitive and non-competitive inhibition. 4. ATP, thymidine triphosphate, UTP, GTP and CTP did not completely inhibit hydrolysis of AMP, IMP and UMP; the concentrations of ATP required to inhibit AMP and IMP hydrolysis by 50% were 12 and 230μm respectively. 5. Non-hyperbolic curves relating activity to UMP concentration were obtained in the presence and absence of triphosphates. 6. After fractionation on Sephadex G-200 columns a single peak of 5′-nucleotidase activity (particle weight 120000–125000) was obtained with AMP, IMP and GMP as substrates. UMP hydrolysis was catalysed by enzyme in this peak and in two slower peaks corresponding to apparent particle weights of 32000 and 16000; a single component (particle weight 120000), reacting with UMP and insensitive to UTP inhibition, was obtained when the column was eluted with buffer containing 1mm-UMP. 7. The possible significance of the results in the regulation of tumour-cell 5′-nucleotidase is discussed. PMID:5775689

    Objective: The present study was undertaken to evaluate the antitumor and antioxidant status of ethanol extract of Terminalia catappa leaves against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Materials and Methods: The leaves powder was extracted with Soxhlet apparatus and subjected to hot continuous percolation using ethanol (95% v/v). Tumor bearing animals was treated with 50 and 200 mg/kg of ethanol extract. EAC induced in mice by intraperitoneal injection of EAC cells 1 × 106 cells/mice. The study was assed using life span of EAC-bearing hosts, hematological parameters, volume of solid tumor mass and status of antioxidant enzymes such as lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) activities. Total phenolics and flavonoids contents from the leaves extract were also determined. Results: Total phenolics and flavonoids contents from the leaves extract were found 354.02 and 51.67 mg/g extract. Oral administration of ethanol extract of T. catappa (50 and 200 mg/kg) increased the life span (27.82% and 60.59%), increased peritoneal cell count (8.85 ± 0.20 and 10.37 ± 0.26) and significantly decreased solid tumor mass (1.16 ± 0.14 cm2) at 200 mg/kg as compared with EAC-tumor bearing mice (P < 0.01). Hematological profile including red blood cell count, white blood cell count, hemoglobin (11.91 ± 0.47 % g) and protein estimation were found to be nearly normal levels in extract-treated mice compared with tumor bearing control mice. Treatment with T. catappa significantly decreased levels of LPO and GSH, and increased levels of SOD and CAT activity (P < 0.01). Conclusion: T. catappa exhibited antitumor effect by modulating LPO and augmenting antioxidant defense systems in EAC bearing mice. The phenolic and flavonoid components in this extract may be responsible for antitumor activity. PMID:24130380

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

    PubMed

    Reynafarje, B; Lehninger, A L

    1973-06-01

    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).

    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. PMID:26319226

    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

    Earlier studies have shown that 2-deoxy-D-glucose (2-DG), a glucose analogue and inhibitor of glycolytic ATP production significantly enhances the cytotoxic effects of anticancer agents like topoisomerase inhibitors (etoposide and camptothecin) and a radiomimetic drug (bleomycin) in established human tumor cell lines. Therefore, combination of 2-DG and DNA damage causing cytotoxic agents could be very useful in enhancing local tumor control. The purpose of the present studies was to investigate the therapeutic effects of etoposide and 2-DG in Ehrlich ascites tumor (EAT) bearing mice, grown as solid tumor as well as in the ascites form. Cell growth, cell cycle perturbations (flow cytometry), cytogenetic damage (micronuclei assay) and apoptosis (DNA content, morphological changes) were studied as parameters of cellular response, while delay in tumor growth and cure rate (tumor free survival) were evaluated as parameters of systemic response. Body weight and general condition as well as the damage to bone marrow and spleen was monitored to evaluate normal tissue toxicity. Intraperitoneal administration of etoposide (30 mg/Kg b. wt.) resulted in significant tumor growth delay and cure (approximately 11%) only in subcutaneous tumors leading to local tumor control. When etoposide was combined with 2-DG (2 g/Kg b. wt.; i.v./i.p.; 4 h after etoposide injection), these effects were further enhanced resulting in a cure rate of approximately 22% in case of subcutaneous tumors and 20% in ascites bearing mice. Analysis of cells obtained from ascitic fluid as well as solid tumors during follow up clearly showed that etoposide induced cell death was mainly due to apoptosis, which was enhanced further by 2-DG. Although, there was a significant level of toxicity revealed by reduced animal survival, decrease in body weight and damage to sensitive organ status like spleen and bone marrow at 60 mg/Kg b. wt. of etoposide, it was not significant at 30 mg/Kg b.wt. 2-DG, however, did not

    A 40-year-old woman was admitted due to an urticarial rash that was attributed to recent onset of methimazole treatment for a diagnosis of Grave's disease. The patient had no prior significant medical history and used no medications, including over-the-counter or herbal medications. Her sister had Grave's disease. On admission, the patient received corticosteroids with improvement in her rash. On the second day of the hospitalization, the patient complained of abdominal discomfort. Abdominal ultrasound revealed a large amount of new onset ascites. Peritoneal tap yielded a milky fluid with high triglyceride level (12.2 mmol/L or 1080 mg/dL), consistent with chylous ascites. After discontinuation of the methimazole, the ascites disappeared. The patient later underwent therapeutic thyroidectomy, after which all features of thyrotoxicosis had improved. PMID:26366308

    Flow cytometry is widely used in many laboratories for automated nucleated cell counts and their differentiation in body fluids. The implementation of new reflex testing rules on these automated instruments could open new frontiers in laboratory workflow, improving characterization of body fluids and clinical diagnosis and decreasing costs. Ascitic (150) and pleural (33) fluids were collected and assessed by XE-5000 and optical microscopy. Cell counts performed with the methods showed a Pearson's correlation of 0.98 (p < 0.0001), Passing-Bablok regression y = 0.99x + 2.44, and bias of 32.3. In ascitic fluids, the best diagnostic performance was found for polymorphonuclear and neutrophil counts on XE-5000, which exhibited areas under the curve (AUCs) 0.98 (p < 0.0001) and 0.99 (p < 0.0001), respectively. In pleural fluids the best diagnostic performance was found for polymorphonuclear percent parameter, which displayed 0.97 (p < 0.0001). Specific reflex test rules based on these parameters were characterized by 92% diagnostic concordance, 1.00 sensitivity, and 0.84 specificity with optical microscopy. The application of a set of reflex testing rules may improve the diagnostic performance of XE-5000, increasing its reliability for routine automated cell count in body fluids. We acknowledge that further studies should be planned to validate our findings according to clinical data.

    MAT-B1 and MAT-C1 ascites sublines of the 13762 rat mammary adenocarcinoma both contain sialomucin as a major cell surface component and are resistant to cytolysis by normal rat spleen lymphocytes [3 +/- 2% (SD) and 0 +/- 1%, respectively]. Susceptibility to lysis did not increase following treatment of cells with neuraminidase, fucosidase, or alpha- or beta-galactosidase. Treatment with trypsin significantly increased the susceptibility of MAT-B1 (14 +/- 3%) but not MAT-C1 (5 +/- 2%). Following 1 month in culture, the sialomucin content of MAT-B1 cells dropped from 30% to 8% (determined by glucosamine labeling) and natural cell-mediated cytolysis increased to 16 +/- 4%, whereas the sialomucin content and susceptibility of MAT-C1 cells did not change. The results indicate that the relatively minor changes associated with removal of cell surface sialic acid or fucose residues do not result in increased susceptibility of the ascites cells to cytolysis. However, susceptibility of MAT-B1 cells to lysis by normal rat spleen lymphocytes was inversely correlated with the amount of major glycoprotein (r = -0.96).

    The aim of this study is to investigate the antitumor activity of Plantago major L. extract in Ehrlich ascites tumor (EAT) bearing Balb/C mice in vivo. Thirty male Balb/C mice were divided into 5 groups: 3 treatment groups and 2 control groups (6 per group). Treatment groups and the negative control group were injected with EAT (1 x 10(6) cells) intraperitoneally to develop ascites tumor. P. major L. extract (1%, 2% and 3% concentration extracts, 0.1 ml/day/mouse) were given p.o. for 10 alternate days. The control group was treated with 0.9% NaCl solution (0.1 ml/day/mouse). The changes of body weight in animals were recorded. On the 11th day, all of the mice were sacrified and their tissues were stained with haematoxylen and eosin for pathological studies. Body weights of in 3 treatment groups and the negative control group were elevated because of tumor burden. The maximal weight gain was recorded in the negative control group and the minimal weight gain was recorded in Group I. Pathological studies showed that P. major L. extract (especially 1% concentration) has inhibitive effect on EAT. P. major has an inhibitory effect on EAT in a dose dependent manner.

    Background Sepsis-induced inflammation in the gut/peritoneal compartment occurs early in sepsis, and can lead to acute lung injury (ALI). We have suggested that inflammatory ascites drives the pathogenesis of ALI, and that removal of ascites with an abdominal wound vacuum prevents ALI. We hypothesized that the time- and compartment-dependent changes in inflammation that determine this process can be discerned using Principal Component Analysis (PCA) and Dynamic Bayesian Network (DBN) inference. Methods To test this hypothesis, data from a previous study were analyzed using PCA and DBN. In that study, two groups of anesthetized, ventilated pigs were subjected to experimental sepsis via intestinal ischemia/reperfusion and placement of a peritoneal fecal clot. The Control Group (n=6) had the abdomen opened at 12 hrs post injury (T12) with attachment of a passive drain. The Peritoneal Suction Treatment (PST) Group (n=6) was treated in an identical fashion except that a vacuum was applied to the peritoneal cavity at T12 to remove ascites and maintained until T48. Multiple inflammatory mediators were measured in ascites and plasma and related to lung function (PaO2/FiO2 ratio [PF] and Oxygen Index [OI]) using PCA and DBN. Results PST prevented ALI based on lung histopathology, whereas Control animals developed ALI. Principal Component Analysis revealed that local to the insult (i.e. ascites), primary pro-inflammatory cytokines play a decreased role in the overall response in the treatment group as compared to control. In both groups, multiple, nested positive feedback loops were inferred from DBN, which included interrelated roles for bacterial endotoxin, interleukin-6, transforming growth factor-β1, C-reactive protein, PF, and OI. Von Willebrand Factor was an output in Control, but not PST, ascites. Conclusions These combined in vivo and in silico studies suggest that in this clinically realistic paradigm of sepsis, endotoxin drives the inflammatory response in the

    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

    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

    Background/Aim: This study intends to determine the correlation of a patient's hepatic venous pressure gradient (HVPG) measurement with six factors: Child–Turcotte–Pugh (CTP) score, model for end-stage liver disease (MELD) score, presence of ascites, size of varices, presence of variceal bleeding, and an etiology of cirrhosis. The study also aims to identify the predictors of higher HVPG measurements that can indirectly affect the prognosis of cirrhotic patients. Patients and Methods: Thirty patients diagnosed with cirrhosis were enrolled prospectively and each patient's HVPG level was measured by the transjugular catheterization of the right or middle hepatic vein. The wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP) were measured using a 7F balloon catheter. The HVPG level was calculated as the difference between the WHVP and FHVP measurements. Results: The mean HVPG level was higher in alcoholic than in nonalcoholic cirrhosis (19.5 ± 7.3 vs 15.2 ± 4.5 mm Hg, P = 0.13). The mean HVPG was also higher in bleeders compared with nonbleeders (18.5 ± 5.3 vs 10.7 ± 3.1 mmHg, P = 0.001). Patients with varices had a higher mean HVPG level than those without varices (17.4 ± 5.8 vs 11.7 ± 3.9 mmHg, P = 0.04). The difference among the three categories of varices (small, large, and no varices) was statistically significant (P = 0.03). In addition, the mean HVPG level was higher in patients with ascites than in those without ascites (18.7 ± 4.7 vs 11 ± 5.3 mmHg, P = 0.002), and it was significantly higher in patients in CTP class C (21.8 ± 5.5 mmHg) as compared with those in CTP class B (16.9 ± 2.9 mmHg) and CTP class A (10.5 ± 4.1 mmHg; P ≤ 0.001). Conclusion: HVPG levels were significantly higher in patients in CTP class C as compared with those in CTP classes A and B, thereby indicating that an HVPG measurement correlates with severity of liver disease. A high HVPG level signifies more severe liver disease and can predict the

    The presence of malignant ascites in advanced cancer patients is associated with both a poor prognosis and quality of life with a risk of abdominal infection and sepsis. Contemporary noninvasive visualization methods such as ultrasound, computed tomography, and magnetic resonance imaging (MRI) often struggle to differentiate malignant ascites from surrounding tissues. This study aimed to determine the utility of selective H2O imaging in the abdominal cavity with a free radical probe and deuterium oxide (D2O) contrast agent using in vivo dynamic nuclear polarization-MRI (DNP-MRI). Phantom imaging experiments established a linear relationship between H2O volume and image intensity using in vivo DNP-MRI. Similar results were obtained when the radical-D2O probe was used to determine selective and spatial information on H2O in vivo, modeled by the injection of saline into the abdominal cavity of mice. To demonstrate the utility of this method for disease, malignant ascites in peritoneal metastasis animal model was selected as one of the typical examples. In vivo DNP-MRI of peritoneal metastasis animal model was performed 7-21 days after intraperitoneal injection of luciferase, stably expressing the human pancreatic carcinoma (SUIT-2). The image intensity with increasing malignant ascites was significantly increased at days 7, 16, and 21. This increase corresponded to in vivo tumor progression, as measured by bioluminescent imaging. These results suggest that H2O signal enhancement in DNP-MRI using radical-D2O contrast is positively associated with the progression of dissemination and could be a useful biomarker for malignant ascites with cancer metastasis.

    Albumin constitutes approximately one half of the proteins in the plasma and plays a pivotal role in modulating the distribution of fluid between body compartments. Hence it is commonly employed in cirrhotic patients in association with diuretics for the treatment of ascites. Nevertheless, its usefulness is controversial in this condition and well-stated only in some circumstances. The item of safety of the drug appears to be convincing due to the accurate cautions in the course of its preparation. Side effects are described in literature only as sporadic events. Indeed, albumin administration is effective to prevent the circulatory dysfunctions after large-volume paracentesis and renal failure and after Spontaneous Bacterial Peritonitis (SBP). Finally albumin represents, associated with vasoconstrictors, the therapeutic gold standard for the hepatorenal-syndrome (HRS). Physiopathological bases of the therapeutic use of albumin in hepatic cirrhosis consist in both hypoalbuminemia and portal hypertension consequences. In fact, cirrhotic patient with ascites, in spite of hydrosaline retention, shows an effective hypovolemia with peripheral arterial vasodilatation and increase in heart rate. Therefore the effectiveness of albumin administration in the treatment of ascites is due to its plasma volume expander property as well as its efficacy in restoring plasmatic oncotic pressure. Trials are in progress in order to define the effectiveness of the prolonged home-administration of human albumin in the treatment and prevention of ascites. Finally, it has been recently demonstrated that the binding, transport and detoxification capacities of human albumin are severely reduced in cirrhotics and this impairment correlates with the degree of liver failure. Therefore, the next challenge will be to determine whether the alterations of non-oncotic properties of albumin are able to forecast mortality in cirrhotics with ascites and exogenous albumin chronic administration will be

    Although the herbal pair of Euphorbia kansui (GS) and Glycyrrhiza (GC) is one of the so-called "eighteen antagonistic medicaments" in Chinese medicinal literature, it is prescribed in a classic Traditional Chinese Medicine (TCM) formula Gansui-Banxia-Tang for cancerous ascites, suggesting that GS and GC may exhibit synergistic or antagonistic effects in different combination designs. 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.

    A simple roller bottle was constructed to house three dialysis tubes, each with a capacity of 75 ml. Cells were grown inside the dialysis tubing, which was immersed in ordinary DMEM medium without serum supplement. Cultures of hybridomas at medium or low density (2 X 10(5) cells/ml) could be expanded directly in the dialysis tubes to attain a high cell density of the order of 10(7)/ml. Continuous gentle stirring of the cells was possible, since the design causes a bubble to oscillate along the length of each tube. The six cell lines tested all gave antibody concentrations of between 1.1 and 2.3 mg/ml at 20 days. Such an in vitro apparatus obviates the need to employ ascites production, because it is as simple or simpler than the injection of mice, and the in vitro product is very rich in antibody, whilst containing low amounts of contaminating proteins.

    Two proteins were purified earlier from solubilized membranes of Ehrlich ascites cells by using a bumetanide-Sepharose affinity column. These proteins were proposed to be constituents of the Na-K-Cl cotransporter. However, the specificity of binding of bumetanide to the cotransporter was insufficient evidence for this proposal. The authors now have direct evidence that the purified protein contains components of the cotransporter. Antiserum raised against the bumetanide-binding proteins strongly inhibits Na-K-Cl cotransport measured by two independent methods. Cotransport was induced by hypertonic challenge and was measured as the bumetanide-sensitive portion of unidirectional Cl influx and as regulatory cell volume increase. In both assays, contransport was strongly inhibited by antiserum. Fab fragments of the antibodies inhibited cotransport to a similar extent.

    The study aimed to investigate the antitumor effect of tetrodotoxin (TTX) and/or doxorubicin (DOX) on Ehrlich ascites carcinoma (EAC)-bearing mice through the investigated biochemical parameters. TTX and/or DOX with or without N-acetylcystiene were administrated after 10 days into EAC-female mice for a period of 2 weeks in six equal doses. Treatment with TTX or DOX caused a significant decrease in the mean tumor weight and an increase in the cumulative mean survival time when compared with EAC group. All the treatments reduced the elevated liver tumor markers and increased liver antioxidant enzymes under investigation in comparison with EAC. Hepatic cells, suffered severely from degeneration and karriolysis in EAC group, revealed some improvement as appearance of healthy hepatocytes by TTX treatment. The present results suggested that TTX had a more powerful inhibitor effect on EAC growth than DOX and TTX plus DOX treatments reflected by antitumor biochemical and histological studies.

    Objectives: Folkloric claims on the use of a mixture of Anogeissus leiocarpus and Terminalia avicennioides root barks in tumor management exist without scientific evidence. This study aimed at investigating the phytochemical constituents and in vitro antiproliferative activity of these plants and their mixture. Materials and Methods: Phytochemical screening was carried out on the aqueous extracts after which various concentrations (0 to 1 000 μg/ml) were incubated with Ehrlich ascites carcinoma cell lines for 3 and 24 hours. Results: The extracts contained alkaloids, tannins, flavonoids, phenolics, saponins, phlobatannins, and terpenes. The separate extracts and their 1:1 mixture significantly (P<0.05) decreased the computed percentage viability of the cell lines in a dose- and time-dependent manner. Conclusions: The antiproliferative activity may be due to the presence of the bioactive compounds in the extracts and has a potential in the management of tumor. PMID:24014915

    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

    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.

    Scorpion venom is a highly complex mixture of about 100-700 different components, where peptides are the major constituents with various biological and pharmacological properties including anticancer activities. In this study, anticancer efficacy of the venom of the Egyptian scorpion Androctonus amoreuxi has been evaluated. In vitro, the human breast cancer MCF-7 cell line was treated with the venom and the IC50 was estimated. In vivo studies, Ehrlich ascites carcinoma (EAC) cells were inoculated into CD-1 mice intraperitoneally to form liquid tumor or subcutaneously to form solid tumor and then treated with intraperitoneal injection with venom (0.22 mg/kg) every other day. The total tumor cells in the ascitic fluid and the size of the solid tumor were assessed after 14 and 30 days, respectively. In addition, the mean survival time (MST), body weight, tumor volume, PCV, viability of tumor cells, CBC, AST, ALP, creatinine, oxidative stress biomarkers (GSH, MDA, PCC), tumor marker Ki67, growth factor VEGF and caspase-3 were measured in normal control, EAC control and venom-treated groups (n = 6). Treatment with venom induced anti-tumor effects against liquid and in solid tumors as indicated by a significant (P < 0.05) reduction in tumor volume/size, count of viable EAC cells, expression of Ki67 and VEGF as well as by remarkable increases in MST and caspase-3 expression as compared to non-treated group. Interestingly, the venom restored the altered hematological and biochemical parameters of tumor-bearing animals and significantly increased their life span. These data indicate to (1) the cytotoxic potential effects of A. amoreuxi on tumor cells via anti-proliferative, apoptotic and anti-angiogenic activities; (2) opening a new avenue for further studies on the anti-cancer effects of this agent.

  11. Antitumor effect of vitamin D-binding protein-derived macrophage activating factor on Ehrlich ascites tumor-bearing mice.

    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. PMID:9893164

    Advanced ovarian cancer (AOC) is one of the leading lethal gynecological cancers in developed countries. Based on the important role of angiogenesis in ovarian cancer oncogenesis and expansion, we hypothesized that the development of an "angiogenic signature" might be helpful in prediction of prognosis and efficacy of anti-angiogenic therapies in this disease. Sixty-nine samples of ascitic fluid- 35 from platinum sensitive and 34 from platinum resistant patients managed with cytoreductive surgery and 1st-line carboplatin-based chemotherapy- were analyzed using the Proteome ProfilerTM Human Angiogenesis Array Kit, screening for the presence of 55 soluble angiogenesis-related factors. A protein profile based on the expression of a subset of 25 factors could accurately separate resistant from sensitive patients with a success rate of approximately 90%. The protein profile corresponding to the "sensitive" subset was associated with significantly longer PFS (8 [95% Confidence Interval {CI}: 8-9] vs. 20 months [95% CI: 15-28]; Hazard ratio {HR}: 8.3, p<0.001) and OS (20.5 months [95% CI: 13.5-30] vs. 74 months [95% CI: 36-not reached]; HR: 5.6 [95% CI: 2.8-11.2]; p<0.001). This prognostic performance was superior to that of stage, histology and residual disease after cytoreductive surgery and the levels of vascular endothelial growth factor (VEGF) in ascites. In conclusion, we developed an "angiogenic signature" for patients with AOC, which can be used, after appropriate validation, as a prognostic marker and a tool for selection for anti-angiogenic therapies.

    Epidemiological and experimental data indicate that high body fat or high dietary fat can be ascribed to the induction of human cancers. Increased level of products of lipid peroxidation and cholesterol-enriched lipid domains in the plasma membrane can favorthe malignant transformation of cells. An effective chemopreventive agent with hypolipaedemic effect will be worthwhile to intervene early in the process of carcinogenesis to eliminate the pre-malignant cells. Apoptotic promoting and antitumor activities of a HMG-Co A reductase inhibitor, atorvatstain were investigated. The antitumor activity was evaluated using Daltons' Lymphoma Ascites (DLA) cell line transplanted ascites tumor model in mice. Proapoptotic activity was evaluated in DLA cell line induced ascites animals after the treatment of atorvastatin (4 and 16 mg/kg, i.p). Apoptosis was analyzed morphologically by staining with giemsa and biochemically by observing the laddering of DNA in agarose gel electrophoresis. In vitro short term cytotoxic activity of atorvatstain was studied by trypan blue dye exclusion method. Doxorubicin was used as the reference standard. Atorvastatin significantly (P < 0.01) inhibited the ascites tumor growth at 16 mg/kg body wt (i.p). The percent increase in life span (%ILS) in the 16 mg/kg treated group was 41.1%. Single dose of atorvastatin (16 mg/kg body wt) was also effective to promote the apoptosis of DLA cells in the ascites tumor bearing mice that was evident from the multiple fragmentation of DNA in agarose gel electrophoresis. Further the morphological analysis of DLA cells aspirated from the atorvastatin treated ascites tumor bearing animals showed 36.34 +/- 6.78% apoptotic cells compared to the control animals (10.50 +/- 3.53%). Concentration of atorvastatin required for the 50% of the cytotoxicity was 30 +/- 2 microg/ml. Results of the study concluded that the antitumor activity of atorvastatin may be due to its proapoptotic and cytotoxic activities. These

    The authors found in an earlier study that Phyllanthus amarus extract could significantly inhibit the solid and ascites tumor development in mice induced by Dalton's lymphoma ascites (DLA) cells. In the present study, the apoptotic effects of P. amarus against DLA cells in culture was evaluated. P. amarus produced significant reduction in cell viability as determined by the MTT assay. It also induces the formation of apoptotic bodies with characteristic features like plasma membrane invagination, elongation, fragmentation, and chromatin condensation. P. amarus at concentrations of 100 and 200 microg/mL is shown to induce DNA fragmentation. Gene expression analysis reveals that P. amarus induces the expression of caspase-3 and inhibits the expression of Bcl-2, which is an antiapoptotic protein. So the present study provides some insights into the possible mechanism by which P. amarus brings about apoptosis and growth inhibition in DLA cells. PMID:19223368

    This study was designed to investigate the impact of ultra-filtration extract mixture from Astragals mongholicus (UEMAM) o radiosensitivity of H22 ascitic tumor in mice to 12C6+ ions radiation. The H22 ascitic tumor model was established in mice by intraperitoneal injection of 0.2 mL H22 ascitic cells. The animals were subsequently divided into 4 groups randomly, treated with normal saline, UEMAM, heavy ion beam radiotherapy and UEMAM plus heavy ion beam radiotherapy, respectively. The body weights, abdomen circumference of the mice were measured and the mouse behavior was monitored every day; survival time was recorded to evaluate life extension effect; flow cytometry technique was used to detect H22 cell apoptosis and cell cycle; protein levels of p53, Bax, Bcl-2 and cleaved Caspase-3 were analyzed by Western blot; the single cell gel electrophoresis was used to detect the level of deoxyribonucleic acid damage (DNA damage). The results suggest that UEMAM significantly increased survival time, and decreased body weights and abdomen circumference over the saline control group. The treatment increased cell apoptosis, cycle arrest and DNA damage compared to the saline control group. UEMAM significantly enhanced the therapeutic effect of heavy ion beam radiation in survival time, and decreased body weights and abdomen circumference in the tumor-baring mice. The combination increased cell apoptosis, cycle arrest and DNA damage compared to the radiotherapy group. The results of Western blot suggest that the treatment significantly enhanced p53-induced apoptotic signals. The experiment discovered that UEMAM could improve radiosensitivity of H22 ascitic tumor through activation of p53-mediated apoptotic signal pathway. PMID:27169282

    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. PMID:27033704

    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.

    Concentrations of double-stranded RNA above about 0.1 μg/ml inhibit translation of encephalo-myocarditis viral RNA and mouse globin messenger RNA in extracts of Krebs II ascites cells. Protein synthesis initially proceeds at the control rate, then abruptly shuts off in a manner similar to that observed in reticulocyte lysates [Hunt, T. & Ehrenfeld, E. (1971) Nature New Biol. 230, 91-94]. Substantially higher concentrations of double-stranded RNA are required to give this effect in ascites extracts. Subcellular fractions of Krebs II ascites cells contain a nucleolytic activity capable of digesting several natural and synthetic double-stranded RNAs. This nuclease is most active under conditions of protein synthesis, and part of the activity remains associated with ribosomes upon sedimentation. It is probably because of digestion of double-stranded RNA by this nuclease that higher concentrations of double-stranded RNA are required for inhibition of protein synthesis in Krebs cell extracts than in reticulocyte lysates.

    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

    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.

    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

    We report a case of a 49-year-old male patient with abdominal distension and diffuse stomach cramps associated with peripheral eosinophilia. Treatment for eosinophilic parasitosis was not effective. After a few weeks, the patient developed acute obstructive abdomen with ascites, which was atypically improved with the use of antispasmodics and analgesics. Upper digestive endoscopy, colonoscopy and histopathologic examination of the gastric and intestinal mucosa did not show any significant changes. Video laparoscopic biopsy of the mesenteric lymph node and peritoneum revealed a nonspecific chronic inflammatory process with intense diffuse tissue eosinophilia. Complementary tests revealed right-sided pleural effusion and increased serum immunoglobulin E levels, with altered D-xylose absorption test results. The patient was treated with a hypoallergenic diet and an oral corticosteroid; the symptoms resolved and the laboratory test results improved. Eosinophilic gastroenteritis is a rare inflammatory disease characterized by eosinophilic infiltration in the wall of the gastrointestinal tract. The clinical presentation varies according to the affected site and the depth and extent of digestive tract involvement. This case report, which presents the rare simultaneous involvement of the mucosal, muscular and serosal layers, aims to describe and discuss the clinical and therapeutic aspects of eosinophilic gastroenteritis as well as its progression.

    Boswellic acid (BA) is known for its ability to trigger apoptosis as well as to inhibit angiogenesis in tumor tissue. In this study, we investigated the effect of BA on the IL-6-STAT-3 signalling pathway in irradiated mice bearing solid tumors of Ehrlich ascites carcinoma (EAC). For this, we administered BA (25 mg·(kg body mass)(-1)·day(-1), by intraperitoneal injection) to mice with EAC, and then exposed them to 4 Gy of gamma radiation. Data analyses of the results revealed a specific impact from BA on IL-6R mRNA and survivin mRNA in EACs and irradiated EAC-bearing mice. Also, significant improvements were observed in the protein expression of JAK-1, P-JAK-1, STAT-3, P-STAT-3, and caspase-3, as well as VEGF and IL-6 levels. We propose that BA interfered with IL-6-STAT-3 signal transduction, thereby preventing the activation of caspase-3 and subsequently triggering the process of apoptosis. However, the alternative angiogenesis pathway, which includes the over-expression of VEGF and which depends on IL-6-STAT-3 signalling, was inhibited by the action of BA. Thus, we recommend that therapeutic strategies for cancer should include treatment with BA.

    The aim of the present study was to investigate the influence of a nonselective COX1/COX2 inhibitor (indomethacin) on tumor growth of Ehrlich Ascites Tumor (EAT) in mice, using as parameters the tumor growth and cytokine profile. Mice were inoculated with EAT cells and treated with indomethacin. After 1, 3, 6, 10, and 13 days the animals were evaluated for the secretion of TNFα, IL-1α, IL-2, IL-4, IL-6, IL-10, and IL-13 and PGE2 level in peritoneal cavity. The results have shown that EAT induces PGE2 production and increases tumor cells number from the 10th day. The cytokine profile showed EAT induces production of IL-6 from 10th day and of IL-2 on 13th day; the other studied cytokines were not affected in a significant way. The indomethacin treatment of EAT-bearing mice inhibited the tumor growth and PGE2 synthesis from the 10th day. In addition, the treatment of EAT-bearing mice with indomethacin has stimulated the IL-13 production and has significantly inhibited IL-6 in the 13th day of tumor growth. Taken together, the results have demonstrated that EAT growth is modulated by PGE2 and the inhibition of the tumor growth could be partly related to suppression of IL-6 and induction of IL-13.

    Diabetes mellitus is a multifunctional disorder with several causes and multiple consequences. Nutraceuticals play a vital role in ameliorating diabetic condition. The stems of the plant, Tinospora cordifolia (T. cordifolia) are often used in Ayurvedic medicine for the management of diabetes. Earlier studies have shown that T. cordifolia to be a potent antidiabetic plant material by virtue of being rich in nutraceuticals. In the present study we were interested to know if, T. cordifolia stem extracts are able to promote glucose uptake through glucose transporters, 1 (GLUT1) and 3 (GLUT3), which are responsible for basal glucose uptake. Hence, Ehrlich ascites tumor (EAT) cells were chosen as a model which harbours both GLUT1 and GLUT3 and glucose uptake was measured using a fluorescent analog 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-D-glucose (2-NBDG). Serially, solvent extracted T. cordifolia stems, especially water, ethanol and methanol extracts showed glucose uptake activity. Uptake was stimulated in a dose dependent manner at dosages of 1-100 μg. Glucose-stimulating activity does not seem to be solely due to polyphenol content since methanol extract, with high amount of polyphenol content (9.5 ± 0.1 g kg(-1)), did not stimulate higher glucose uptake activity when compared to water extract.

    Vincristine pharmacokinetic, tumour uptake and therapeutic characteristics were investigated here in order to elucidate the processes underlying the enhanced efficacy observed for vincristine entrapped in small (120 nm) distearoylphosphatidylcholine/cholesterol liposomes. Plasma vincristine levels after intravenous (i.v.) injection are elevated more than 100-fold in the liposomal formulation compared with free drug in tumour-bearing as well as non-tumour-bearing mice over 24 h. Biodistribution studies demonstrate that the extent and duration of tumour exposure to vincristine is dramatically improved when the drug is administered i.v. in liposomal form. Specifically, 72 h trapezoidal area under the curve values for liposomal vincristine in the murine L1210 ascitic and B16/BL6 solid tumours are 12.9- to 4.1-fold larger, respectively, than observed for free drug. Similar to previous results with the L1210 model, increased drug delivery to the B16 tumour results in significant inhibition of tumour growth, whereas no anti-tumour activity is observed with free vincristine. Comparisons of drug and liposomal lipid accumulation in tumour and muscle tissue indicate that the enhanced efficacy of liposomal vincristine is related predominantly to drug delivered by liposomes to the tumour site rather than drug released from liposomes in the circulation. Consequently, improvements in liposomal vincristine formulations must focus on factors that increase uptake of liposomes into tumour sites as well as enhance liposomal drug retention in the circulation.

    Objective To evaluate the antineoplastic activity of Eucalyptus extract (EuE) against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Methods Preliminary examination of four plant extracts (namely Eucalyptus, Costus, Azadirachta, Feronia) has been done by observing the reduction ability of number of EAC cells in previously inoculated Swiss albino mice. Among them as EuE showed maximum capability, the whole study has been conducted with EuE only. Important parameters viz. enhancement of life span, reduction of average tumor weight etc. have been studied. In addition the effects of EuE on hematological parameters in both normal and EAC inoculated mice have been measured. Effect of EuE on normal peritoneal cells has also been studied. Results : EuE reduced tumor burden remarkably. It reduced the tumor growth rate and enhanced the life span of EAC bearing mice noticeably. It reversed back the hematological parameters towards normal, reduced the trasplantability of EAC cells and enhanced the immunomodulatory effects in mice. The host toxic effect of EuE in mice is minimum and mostly reversible with time. All such data have been compared with those obtained by running parallel experiments with bleomycin at dose 0.3 mg/kg (i.p.). Conclusions The Eucalyptus extract may be considered as a potent anticancer agent for advanced researches. PMID:23569937

    The template activities of the 60-70S RNA complex and of the 30-40S subunit RNA species of Rous sarcoma virus were tested in a cell-free protein-synthesizing system from mouse ascites Krebs II cells. Stimulation of protein synthesis over the endogenous background was about 2-fold with 30-40S viral RNA and about 1.3-fold with 60-70S viral RNA as template. Analysis by sodium dodecyl sulfate-gel electrophoresis showed that the predominant polypeptide synthesized in vitro in response to 30-40S RNA of Rous sarcoma virus had a molecular weight of 75,000-80,000. This polypeptide could be precipitated by antiserum against the group-specific antigens of the virus, although its molecular weight is higher than that of virion group-specific antigen proteins. Analysis of tryptic digests of the protein made in vitro indicates similarity to tryptic digests from authentic virion group-specific proteins. It is concluded that part of the RNA from Rous sarcoma virus is translated in vitro into a high-molecular-weight protein, perhaps a precursor of the virion group-specific proteins.

    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. PMID:16221516

  12. Effective plasma volume in cirrhosis with ascites. Evidence that a decreased value does not account for renal sodium retention, a spontaneous reduction in glomerular filtration rate (GFR), and a fall in GFR during drug-induced diuresis

    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

    Recent evidence implicates the volume-regulated anion current (VRAC) and other anion currents in control or modulation of cell cycle progression; however, the precise involvement of anion channels in this process is unclear. Here, Cl- currents in Ehrlich Lettre Ascites (ELA) cells were monitored during cell cycle progression, under three conditions: (i) after osmotic swelling (i.e., VRAC), (ii) after an increase in the free intracellular Ca2+ concentration (i.e., the Ca2+-activated Cl- current, CaCC), and (iii) under steady-state isotonic conditions. The maximal swelling-activated VRAC current decreased in G1 and increased in early S phase, compared to that in G0. The isotonic steady-state current, which seems to be predominantly VRAC, also decreased in G1, and increased again in early S phase, to a level similar to that in G0. In contrast, the maximal CaCC current (500 nM free Ca2+ in the pipette), was unaltered from G0 to G1, but decreased in early S phase. A novel high-affinity anion channel inhibitor, the acidic di-aryl-urea NS3728, which inhibited both VRAC and CaCC, attenuated ELA cell growth, suggesting a possible mechanistic link between cell cycle progression and cell cycle-dependent changes in the capacity for conductive Cl- transport. It is suggested that in ELA cells, entrance into the S phase requires an increase in VRAC activity and/or an increased potential for regulatory volume decrease (RVD), and at the same time a decrease in CaCC magnitude.

    The chemomodulatory activity of Alstonia scholaris extract (ASE) was studied in combination with berberine hydrochloride (BCL), a topoisomerase inhibitor, in Ehrlich ascites carcinoma-bearing mice. The tumor-bearing animals were injected with various doses of ASE, and 8 mg/kg of BCL (one-fifth of the 50% lethal dose) was combined with different doses of ASE (60-240 mg/kg). The combination of 180 mg/kg of ASE with 8 mg/kg of BCL showed the greatest antitumor effect; the number of tumor-free survivors was more, and the median survival time and the average survival time increased up to 47 and 40.5 days, respectively, when compared with either treatment alone. Similarly, when 180 mg/kg of ASE was combined with different doses of BCL (2-12 mg/kg), a dose-dependent increase in the anticancer activity was observed up to 8 mg/kg of BCL. However, a further increase in the BCL dose to 10 and 12 mg/kg resulted in toxic side effects. The best effect was observed when 180 mg/kg of ASE was combined with 6 or 8 mg/kg of BCL, where an increase in the antineoplastic activity was reported. The efficacy of the combination of 180 mg/kg of ASE was also tested with 6 mg/kg body weight of BCL in various stages of tumorigenesis, and it was effective when given in the early stages, although the efficiency decreased with an increase in the tumor developmental stages.

    The K+ and Cl− currents activated by hypotonic cell swelling were studied in Ehrlich ascites tumour cells using the whole-cell recording mode of the patch-clamp technique. Currents were measured in the absence of added intracellular Ca2+ and with strong buffering of Ca2+. K+ current activated by cell swelling was measured as outward current at the Cl− equilibrium potential (ECl) under quasi-physiological gradients. It could be abolished by replacing extracellular Na+ with K+, thereby cancelling the driving force. Replacement with other cations suggested a selectivity sequence of K+ > Rb+ > NH4≈ Na+≈ Li+; Cs+ appeared to be inhibitory. The current-voltage relationship of the volume-sensitive K+ current was well fitted with the Goldman-Hodgkin-Katz current equation between -130 and +20 mV with a permeability coefficient of around 10−6 cm s−1 with both physiological and high-K+ extracellular solutions. The class III antiarrhythmic drug clofilium blocked the volume-sensitive K+ current in a voltage-independent manner with an IC50 of 32 μM. Clofilium was also found to be a strong inhibitor of the regulatory volume decrease response of Ehrlich cells. Cell swelling-activated K+ currents of Ehrlich cells are voltage and calcium insensitive and are resistant to a range of K+ channel inhibitors. These characteristics are similar to those of the so-called background K+ channels. Noise analysis of whole-cell current was consistent with a unitary conductance of 5.5 pS for the single channels underlying the K+ current evoked by cell swelling, measured at 0 mV under a quasi-physiological K+ gradient.

    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. PMID:26733170

    Background/Aims Spontaneous bacterial peritonitis (SBP) contributes to poorer short-term mortality in cirrhotic patients with ascites. However, it is unknown how long the effect of the first SBP event persists in these patients. Methods The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify and enroll 7,892 cirrhotic patients with ascites who were hospitalized between January 1 and December 31, 2007. All patients were free from episodes of SBP from 1996 to 2006. Results The study included 1,176 patients with SBP. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in this group were 21.8%, 38.9%, 57.5%, and 73.4%, respectively. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in the non-SBP group were 15.7%, 32.5%, 53.3%, and 72.5%, respectively. After adjusting for gender, age, and other medical comorbidities, the adjusted hazard ratios of SBP for 30-day, 30- to 90-day, 90-day to 1-year, and 1- to 3-year mortality were 1.49 (95% confidence interval [CI], 1.30 to 1.71), 1.19 (95% CI, 1.02 to 1.38), 1.04 (95% CI, 0.90 to 1.20), and 0.90 (95% CI, 0.77 to 1.05), respectively, compared with the non-SBP group. Conclusions The effect of SBP on the mortality of cirrhotic patients with ascites disappeared in those surviving more than 90 days after the first SBP event. PMID:27563023

    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.

    Hypoxia-inducible factor 1 (HIF-1) is a ubiquitously expressed heterodimeric transcription factor that mediates adaptive responses to hypoxia in all nucleated cells of metazoan organisms. Hypoxia-inducible factor 1α is involved in the pathogenesis of pulmonary hypertension in humans and animals, but whether HIF-1α is associated with the development of pulmonary hypertension syndrome (also known as ascites syndrome, AS) in broiler chickens has not been determined. In the present paper we addressed this issue by measuring the expression of HIF-1α mRNA in hearts and lungs of broiler chickens with AS induced by excess salt in drinking water. We conducted 2 experiments. The first experiment was used to observe the effects of excess salt on AS incidence. The results indicated that total incidence (20%) of AS in excess salt group (receiving 0.3% NaCl in drinking water) was much higher compared with the control group (receiving tap water) over a 43-d time course (P < 0.05). In the second experiment, we determined mean pulmonary arterial pressure (mPAP), ascites heart index (AHI), and expression of HIF-1α mRNA in lungs and hearts of broiler chickens after the excess salt treatment. Our results showed that excess salt induced pulmonary hypertension (indicated by higher mPAP) and right ventricular hypertrophy (greater ascites heart index) in broiler chickens. Meanwhile, the expression levels of HIF-1α mRNA in lungs and hearts were significantly increased at different time points in the excess salt group compared with the control group. Linear correlation analysis showed that the expression of HIF-1α mRNA in lungs was significantly positively correlated with mPAP (correlation coefficient = 0.79, P < 0.001), demonstrating that expression of HIF-1α mRNA was gradually increased in the excess salt group with the increase of pulmonary arterial pressure. In addition, the ascitic chickens showed significantly higher transcriptional levels of HIF-1α in hearts and lungs

    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

Direct sequencing of PCR products revealed 62% mixed chromatograms predominantly belonging to Gram-positive bacteria. Terminal restriction fragment length polymorphism (T-RFLP) results of a sample subset confirmed sequence data showing polymicrobial DNA contents in 67% of bactDNA-positive ascites samples.

    Enteropathy-associated T-cell lymphoma (EATL), an intestinal tumor of intraepithelial T lymphocytes, is a rare and highly aggressive disease. We herein describe a case of type II EATL with massive pyoid ascites in which a histological examination could not be performed despite emergency laparotomy that was successfully diagnosed using flow cytometry and the cell block technique to analyze the celomic fluid. This case suggests that EATL should be included in the differential diagnosis of pyoid ascites of unknown origin and that flow cytometry and the cell block technique of assessing celomic fluid are useful procedures for diagnosing EATL, especially in cases in which conducting a histological examination is impossible.

    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

    Tumour cell recruitment of the JB-1 and L 1210 ascites tumour has been demonstrated directly by a double-labelling method with [14C]- and [3H]-thymidine (TdR). After [14C]-labelling of all proliferating tumour cells by multiple injections of [14C]TdR, recruitment of resting cells was stimulated by removal of the majority of tumour cells, i.e. by maximum aspiration of ascitic fluid. The number of recruited resting cells in the remaining tumour that re-enter the cell cycle after stimulation was demonstrated directly by a single injection of [3H]TdR given at different times after stimulation. The increase in the percentage of purely [3H]-labelled cells, i.e. recruited cells, with increasing time after stimulation, shows that recruitment is not a synchronous but a continuous process, the maximum of which occurs earlier in the case of the L 1210 than the JB-1 tumour. This suggests that there seems to be a relationship between the time required for maximum recruitment and the corresponding cell cycle parameters of the unperturbed tumour. There is a transitory increase of the growth fraction to about 100% and a considerable shortening of the cycle time at the maximum of recruitment.

    The murine ascites sarcoma 180 cells were used to test the in vivo effectiveness of mitomycin C (MMC) and gamma-radiation applied in combination. The action of intraperitoneal administration of MMC and/or whole-body gamma irradiation on sarcoma 180 tumor bearing Swiss albino mice was investigated by studying the template activity of isolated tumor chromatin. The Km value for transcription of 10 Gy-irradiated chromatin was found to decrease with time implying an increase in the template efficiency with respect to that of the unirradiated control. Maximum decrease in Km was observed after 24 h of irradiation. MMC treatment (7 mg/kg body weight of mouse) for 18 h resulted in an inhibition of the transcription rate. Severe inhibition in the template activity was found when cells were subjected to MMC treatment 18 h prior to irradiation with 10 Gy. Susceptibility of tumor chromatin to DNase II followed the same pattern as observed in the case of transcription indicating structural alteration of the treated chromatin. The data showed that DNA damage and its consequences produced in the ascites cells by prior treatment of MMC were not repaired during the 18 h period after which the application of radiation enhanced cytotoxicity.

    Haptoglobin (Hp) is an acute-phase protein that is produced by the liver to capture the iron that is present in the blood circulation, thus avoiding its accumulation in the blood. Moreover, Hp has been detected in a wide variety of tissues, in which it performs various functions. In addition, this protein is considered a potential biomarker in many diseases, such as cancer, including ovarian carcinoma; however, its participation in the cancerous processes has not yet been determined. The objective of this work was to demonstrate the expression of Hp and its receptor CCR2 in the ovarian cancer cells and its possible involvement in the process of cell migration through changes in the rearrangement of the actin cytoskeleton using western blot and wound-healing assays and confirming by confocal microscopy. Ovarian cancer cells express both Hp and its receptor CCR2 but only after exposure to ascitic fluid, inducing moderated cell migration. However, when the cells are exposed to exogenous Hp, the expression of CCR2 is induced together with drastic changes in the actin cytoskeleton rearrangement. At the same time, Hp induced cell migration in a much more efficient manner than did ascitic fluid. These effects were blocked when the CCR2 synthetic antagonist RS102895 was used to pretreat the cells. These results suggest that Hp-induced changes in the cell morphology, actin cytoskeleton structure, and migration ability of tumor cells, is possibly “preparing” these cells for the potential induction of the metastatic phenotype.

    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

    In the efficient treatment described (Anticancer Research 9: 941-946, 1989) some compounds (64Cu and thioproline) act against the malignant genomes, and other components (metal ions, amino acids, vitamin D2, thyroxine and chelating substances) act against the functioning of the host cells having the cancer functioning (cancer cells). The experiments described show that this treatment developed with mice injected on day zero with 5 x 10(5) Krebs ascitic cells, is also efficient for mice bearing a spontaneous malignant tumor even if it is not an ascitic tumor. After the decrease in weight due to the loss of the tumor, a typical weight evolution was observed characterized by a second weight increase followed by a decrease leading to normal weight. This last weight remained stable. This typical weight evolution in tumor-free mice (after spontaneous tumor or experimental Krebs ascitic tumor) was related to the age of the tumor at the beginning of the treatment, that is, according to our hypothesis (Anticancer Res 9:955-960, 1989) to the cancer evolution emphasizing the great importance of all physiological phenomena related to this cancer course. To test the consequence of this treatment, some of these tumor-free mice were injected with 5 x 10(5) ascitic cells. No tumor developed in these tumor-free mice meaning that they also were tumor-resistant. This last result is in agreement with the forecast of the systemic analysis on which the efficient treatment was based.

    Cultures of a permanently in suspension growing line of Ehrlich ascites tumor cells (EATC) were studied regarding their use as a test system for the determination of cytotoxic effects of anaesthetics. These cells, having a comparatively high reduplication rate, are cultured at 37 degrees C in vitro in a chemically defined liquid medium supplemented by 15% horse serum without agitation in a closed system. In order to detect drug effects on the cultures various cellular parameters can be determined due to the suspension character of the cultures without complicated preparatory measures, e.g. cell number or multiplication rate, cell volume, cell volume distribution. Moreover biochemical parameters, such as protein or nucleic acid content, may be estimated after centrifugation of the cultures separately in the cell sediment and the medium supernatant. Applying drugs of various pharmacological groups (cytostatic and anti-inflammatory drugs, local and general anaesthetics) the usefulness of some of these parameters for the detection of cytotoxic effects was studied.

    Possible involvement of the single-strand DNA-binding protein (SSB-protein) in DNA replication in Ehrlich ascite tumour (EAT) cells was studied. There was a direct correlation between the content of SSB-protein in chromatin and the intensity of replicative synthesis of DNA in various preparations of EAT in vitro and in vivo (the computed value of the correlation coefficient was equal to 0.9). It was shown that the addition of exogenous SSB-protein to permeable EAT cells increased the replicative synthesis. It was concluded that although eukaryotic SSB-proteins are not complete analogs of prokaryotic ones, they may participate in DNA replication in eukaryotic cells and, possibly, are intracellular regulators of proliferation.

    Advanced cirrhosis is often complicated by a multi organ failure syndrome which involves many different organs besides the liver. The high morbidity and mortality secondary to this clinical setting is often related to renal dysfunction, either alone or, more frequently, in combination with other organ dysfunction. A clear definition of renal dysfunction, an accurate differential diagnostic process of its different phenotypes as well as of full understanding of its pathophysiological mechanisms are crucial to the development of strategies for the management of this complication. This article is based either on the more recent knowledge on renal dysfunction in advanced cirrhosis or current opinions among the members of the International Club of Ascites (ICA) on the management of this complication, obtained through a survey and discussed during the EASL-ICA Joint Meeting in Berlin in March 2011. It reviews critically our current knowledge and it outlines future perspectives, on the management of renal dysfunction in patients with cirrhosis.

    We aimed to evaluate therapeutic potential of arjunolic acid (AA), in Terminalia Arjuna bark, on Ehrlich Ascites carcinoma (EAC) in-vivo and in-vitro. EAC was induced in fifty female Swiss albino mice. Two doses of AA was used 100 and 250mg/kg. Arjunulic acid reduced tumor volume and cells count. AA decreased EAC cells viability and increased cell toxicity. Moreover, AA reduced TNF-α, IL-1β, TGF-β, TGF-β type I receptor and latency-associated peptide levels associated with elevated IL-10 in-vivo and in-vitro. In conclusion, AA produced antitumor activity against EAC by increasing cytotoxicity and apoptosis and partially blocking the TGF-βR1 and affecting inflammatory cytokine levels. PMID:27470335

    Aim: This study was designed to study the antitumor and antioxidant activity of Uighur medicine abnormal savda munziq (ASMq) in the S180 and Ehrlich ascites carcinoma mice tumor model. Materials and Methods: The serum levels of superoxide dismutase (SOD), malonaldehyde (MDA), and glutathione-catalase (GSH-PX) were analyzed, and the mice were also subjected to a hypoxia tolerance test. Their climbing ability was also analyzed. Results: The findings of the study revealed that ASMq-treatment leads to an increase in blood serum SOD and GSH-PX levels but a decrease in blood serum MDA levels. Moreover, ASMq-treatment enhanced the survival time of mice maintained under hypoxic conditions and improved their mice climbing ability. Conclusions: The results of this study indicate that ASMq has obvious antitumor and antioxidative effects. PMID:22701288

    In a previous study, we showed that (1'S)-acetoxychavicol acetate ((S)-ACA) caused a rapid decrease in glutathione (GSH) levels less than 15 min after exposure. (S)-ACA-induced cell death was reversed by the addition of N-acetylcysteine. In the current study, we investigated the inhibitory activities of 13 derivatives of (S)-ACA on tumor cell viability, intracellular GSH level and GR activity. Correlations were found among a decrease in cell viability, intracellular GSH levels and the activity of GR in Ehrlich ascites tumor cells treated with the various ACA analogues. A test of the 13 derivatives revealed that the structural factors regulating activity were as follows: (1) the para or 1'-position of acetoxyl group (or other acyl group) was essential, (2) the presence of a C2'-C3' double or triple bond was essential, and (3) the S configuration of the 1'-acetoxyl group was preferable.

    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.

    Advanced ovarian cancer (AOC) is one of the leading lethal gynecological cancers in developed countries. Based on the important role of angiogenesis in ovarian cancer oncogenesis and expansion, we hypothesized that the development of an “angiogenic signature” might be helpful in prediction of prognosis and efficacy of anti-angiogenic therapies in this disease. Sixty-nine samples of ascitic fluid- 35 from platinum sensitive and 34 from platinum resistant patients managed with cytoreductive surgery and 1st-line carboplatin-based chemotherapy- were analyzed using the Proteome ProfilerTM Human Angiogenesis Array Kit, screening for the presence of 55 soluble angiogenesis-related factors. A protein profile based on the expression of a subset of 25 factors could accurately separate resistant from sensitive patients with a success rate of approximately 90%. The protein profile corresponding to the “sensitive” subset was associated with significantly longer PFS (8 [95% Confidence Interval {CI}: 8–9] vs. 20 months [95% CI: 15–28]; Hazard ratio {HR}: 8.3, p<0.001) and OS (20.5 months [95% CI: 13.5–30] vs. 74 months [95% CI: 36-not reached]; HR: 5.6 [95% CI: 2.8–11.2]; p<0.001). This prognostic performance was superior to that of stage, histology and residual disease after cytoreductive surgery and the levels of vascular endothelial growth factor (VEGF) in ascites. In conclusion, we developed an “angiogenic signature” for patients with AOC, which can be used, after appropriate validation, as a prognostic marker and a tool for selection for anti-angiogenic therapies.

    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.

    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.

    The aim of the study was to assess pH, pO2 and pCO2 in peritoneal fluid. The study was conducted on a group of 22 dogs with symptoms of ascites. Group 1 consisted of 4 dogs with adenocarcinoma, group 2--of 6 dogs with glomerulonephritis, group 3 of 8 dogs with hepatic cirrhosis and group 4 of 4 dogs with bacterial peritonitis. An abdominal cavity puncture was performed in all dogs and the fluid was drawn into a heparinized syringe in order to assess pH, pO2 and pCO2 . The analysis of pH in the peritoneal fluid revealed statistically significant differences between group 4 and groups 1 (p=0.01), 2 (p=0.01), and 3 (p=0.01). The lowest pH value compared to the other studied groups was recorded in group 4. In group 4, the pO2 was the lowest compared to the other groups (group 1 p=0.01, group 2 p=0.01, group 3 p=0.01). The value of pCO2 was the highest in group 4 compared to groups 1, 2, and 3. The study found statistically significant differences in pH, pCO2 and pCO2 between group 4 (the group of dogs with bacterial peritonitis) and the other groups of dogs. This was probably linked to the pathogenesis of peritonitis. As a result of an inflammatory reaction within the peritoneal cavity, there is an increase in fibrin accumulations leading to a decreased oxygen supply causing the oxidative glucose metabolism to change into a non-oxidative glucose metabolism. This, in turn, causes a decrease in pH, acidosis, and a low oxidoreduction potential. It also impairs phagocytosis and activates proteolytic enzymes which create ideal conditions for the growth of anaerobic bacteria. The obtained results indicate that the pH, pO2 and pCO2 may be used to differentiate bacterial peritonitis from ascites of other etiologies.

    Great effort has been paid to identify novel targets for pharmaceutical intervention to control inflammation associated with different diseases. We have studied the effect of signalling inhibitors in the secretion of the proinflammatory and profibrogenic cytokine interleukin (IL)-1β in monocyte-derived macrophages (M-DM) obtained from the ascites of cirrhotic patients and compared with those obtained from the blood of healthy donors. Peritoneal M-DM were isolated from non-infected ascites of cirrhotic patients and stimulated in vitro with lipopolysaccharide (LPS) and heat-killed Candida albicans in the presence or absence of inhibitors for c-Jun N-terminal kinase (JNK), mitogen-activated protein kinase kinase 1 (MEK1), p38 mitogen-activated protein kinase (MAPK) and phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K). The IL1B and CASP1 gene expression were evaluated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The expression of IL-1β and caspase-1 were determined by Western blot. IL-1β was also assayed by enzyme-linked immunosorbent assay (ELISA) in cell culture supernatants. Results revealed that MEK1 and JNK inhibition significantly reduced the basal and stimulated IL-1β secretion, while the p38 MAPK inhibitor had no effect on IL-1β levels. On the contrary, inhibition of PI3K increased the secretion of IL-1β from stimulated M-DM. The activating effect of PI3K inhibitor on IL-1β release was mediated mainly by the enhancement of the intracellular IL-1β and caspase-1 content release to the extracellular medium and not by increasing the corresponding mRNA and protein expression levels. These data point towards the role of MEK1 and JNK inhibitors, in contrast to the PI3K-protein kinase B inhibitors, as potential therapeutic tools for pharmaceutical intervention to diminish hepatic damage by reducing the inflammatory response mediated by IL-1β associated with liver failure.

    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)

  5. Possible interrelationship between changes in F-actin and myosin II, protein phosphorylation, and cell volume regulation in Ehrlich ascites tumor cells.

    Osmotic shrinkage of Ehrlich ascites tumor cells (EATC) elicited translocation of myosin II from the cytosol to the cortical region, and swelling elicits concentration of myosin II in the Golgi region. Rho kinase and p38 both appeared to be involved in shrinkage-induced myosin II reorganization. In contrast, the previously reported shrinkage-induced actin polymerization [Pedersen et al. (1999) Exp. Cell Res. 252, 63-74] was independent of Rho kinase, p38, myosin light chain kinase (MLCK), and protein kinase C (PKC), which thus do not exert their effects on the shrinkage-activated transporters via effects on F-actin. The subsequent F-actin depolymerization, however, appeared MLCK- and PKC-dependent, and the initial swelling-induced F-actin depolymerization was MLCK-dependent; both effects were apparently secondary to kinase-mediated effects on cell volume changes. NHE1 in EATC is activated both by osmotic shrinkage and by the serine/threonine phosphatase inhibitor Calyculin A (CL-A). Both stimuli caused Rho kinase-dependent myosin II relocation to the cortical cytoplasm, but in contrast to the shrinkage-induced F-actin polymerization, CL-A treatment elicited a slight F-actin depolymerization. Moreover, Rho kinase inhibition did not significantly affect NHE1 activation, neither by shrinkage nor by CL-A. Implications for the possible interrelationship between changes in F-actin and myosin II, protein phosphorylation, and cell volume regulation are discussed. PMID:12061817

    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

    In order to investigate the presence of adaptive response in cancerous cells, two monofunctional alkylating agents, namely, ethyl methanesulfonate (EMS) and methyl methanesulfonate (MMS), were employed to treat Ehrlich ascites carcinoma (EAC) cells in vivo. Conditioning dose of 80 mg/kg body weight of EMS or 50 mg/kg body weight of MMS and challenging dose of 240 mg/kg body weight of EMS or 150 mg/kg body weight of MMS were selected by pilot toxicity studies. Conditioned EAC cells when challenged after 8 h time lag resulted in significant reduction in chromosomal aberrations compared to challenging dose of respective agents. As has been proved in earlier studies with normal organisms, even in cancerous cells (EAC), there is presence of adaptive response to methylating and ethylating agents. Furthermore, it is also interesting to note in the present studies that the methylating agent, MMS, is a stronger inducer of the adaptive response than the ethylating agent, EMS.

    Repair of potentially lethal damage (PLD) induced by uv light in synchronized and in plateau-phase cultures of Ehrlich ascites tumor cells was studied by measuring cell survival. In particlar the influence of conditions supporting repair of PLD on growth kinetics was investigated. In synchronized G/sub 1/, S, or G/sub 2/ + M cells as well as in plateau-phase cells, uv light induced, almost exclusively, delay in the next S phase. A significant decrease of this delay was observed when the cells were incubated for 24 hr in balanced salt solution. Repair of PLD after uv irradiation was found to occur in plateau-phase cells and in cells in different phases of the cell cycle provided that after irradiation these were kept under conditions inhibiting cell multiplication (incubation in balanced salt solution or in conditioned medium). The repair time constant t/sub 50/ was significantly higher than those found for X irradiation (5-10 hr compared to 2 hr), and repair was not significantly inhibited by either 20 ..mu..g/ml cycloheximide or 2 mM caffeine in 24 hr.

    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.

    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. PMID:26828226

    The efficacy of the antitumor activity of 1'-acetoxychavicol acetate (ACA), reported to be a suppressor of chemically induced carcinogenesis, was evaluated in Ehrlich ascites tumor cells. ACA treatment resulted in changes in morphology and a dose-dependent suppression of cell viability. Apoptosis, characterized by nuclear condensation, membrane blebbing, cell shrinkage and a significant induction of caspase-3-like protease activity at 8 h in a time-course study were observed. Formation of apoptotic bodies was preceded by lowering of intracellular polyamines, particularly putrescine, and both dose- and time-dependent inhibitory and activation effect by ACA on ornithine decarboxylase (ODC) and spermidine/spermine N(1)-acetyltransferase (SSAT), respectively. Administration of exogenous polyamines prevented ACA-induced apoptosis represented by a reduction in the number of apoptotic bodies and also caused reduction in the induced caspase-3-like protease activity at 8 h. These findings suggest that the anticarcinogenic effects of ACA might be partly due to perturbation of the polyamine metabolic pathway and triggering of caspase-3-like activity, which result in apoptosis.

    Elucidation of the mechanisms underlying potential anticancer drugs continues and unraveling these mechanisms would not only provide a conceptual framework for drug design but also promote use of natural products for chemotherapy. To further evaluate the efficacy of the anticancer activity of 1'-acetoxychavicol acetate (ACA), this study investigates the underlying mechanisms by which ACA induces death of Ehrlich ascites tumor cells. ACA treatment induced loss of cell viability, and Western blotting analysis revealed that the compound stimulated tyrosine phosphorylation of several proteins with 27 and 70 kDa proteins being regulated in both dose- and time-dependent manner prior to loss of viability. Protein tyrosine kinase inhibitor herbimycin A moderately protected cells from ACA-induced toxicity. In addition, cellular glutathione and protein sulfydryl groups were also significantly reduced both dose- and time-dependently during evidence of cell death. Replenishing thiol levels by antioxidant, N-acetylcysteine (NAC), an excellent supplier of glutathione and precursor of glutathione, substantially recovered the viability loss, but the recovery being time-dependent, as late addition of NAC (at least 30 min after ACA addition to cultures) was, however, ineffective. Addition of NAC to ACA treated cultures also abolished tyrosine phosphorylation of the 27 kDa protein. These results, at least partly, identify cellular sulfhydryl groups and protein tyrosine phosphorylation as targets of ACA cytotoxicity in tumor cells.

    The DNA of Novikoff hepatoma ascites cells was found to contain a 3.6-megadalton EcoRI restriction fragment, referred to as EcoRI fragment A (Parker et al., 1979). C0t analyses demonstrated an enrichment of fragment A sequences in Novikoff hepatoma genome relative to normal rat liver DNA. This fragment was cloned in lambda gtWES to determine its molecular structure and sequence organization. The DNA from a positive clone was labeled by nick translation and hybridized to a Southern blot of EcoRI digested Novikoff DNA. Distinct hybrids formed with the region corresponding to fragment A. The greater degree of hybridization to the nucleolar fraction suggested a nucleolar enrichment of fragment A. Fragment A has a PstI site approximately 300 base pairs from one terminus which was used to generate mono-5'-32P-labeled fragments. The larger PStI subfragment, 5500 base pairs, labeled at a single terminus, was used to evolve a restriction enzyme map. The 300 base pair fragment was partially sequenced, revealing the presence of a repetitive sequence "island", TT(GTCT)8(GAAT)5G-. C0t analysis, utilizing the purified clone as a probe, confirmed the enrichment of fragment A sequences in the tumor relative to the normal rat liver control.

    Resting cells in tumours present a major problem in cancer chemotherapy. In the plateau phase of grwoth of the murine JB-1 ascites tumour (i.e. 10 days after 2-5 X 10(6) cells i.p.) large fractions of non-cycling cells with G1 and G2 DNA content (Q1 and Q2 cells) are present, and the fate of these resting cells was investigated after treatment with 1-beta-D-arabinofuranosylcytosine (Ara-C). The experimental work of growth curves, percentage of labelled mitoses curves after continuous labelling with 3H-TdR, and cytophotometric determination of single-cell DNA content in unlabelled tumour cells. Treatment with an i.p. single injection of Ara-C 200 mg/kg in the plateau JB-1 tumour resulted in a significant reduction in the number of tumour cells 1 and 2 days later as compared with untreated controls, while no difference in the number of tumour cells was observed after 3 days. In tumours prelabelled with 3H-TdR 24 hr before Ara-C treatment, a significant decrease in the percentage of labelled mitoses was observed 6-8 hr later followed by a return to the initial value after 12 hr, and a new pronounced fall from 20 hr after Ara-C. The second fall in the percentage of labelled mitoses disappeared when the labelling with 3H-TdR was continued also after Ara-C treatment. Cytophotometry of unlabelled tumour cells prelabelled for 24 hr with 3H-TdR before Ara-C treatment showed 20 hr after Ara-C a pronounced decrease in the fraction of Q1 cells paralleled by an increase in the fraction of unlabelled cells with S DNA content. The results indicate recycling of resting cells first with G2 and later with G1 DNA content, which contribute to the regrowth of the tumours.

    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.

    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.

    Background Malignant ascites (MA) is associated with poor prognosis and limited palliative therapeutic options. Therefore, quality of life (QoL) assessment is of particular importance to demonstrate new treatment value. Following the demonstration of the superiority of catumaxomab and paracentesis over paracentesis on puncture-free survival, this analysis aimed at comparing deterioration in QoL between both the treatment options. Patients and methods In a randomised, multicentre, phase II/III study of patients with MA due to epithelial cell adhesion molecule (EpCAM) positive cancer, the QoL was evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 items (EORTC QLQ-C30) questionnaire at screening, 1, 3 and 7 months after treatment and in the case of re-puncture on the day of paracentesis. Time to first deterioration in QoL was defined as a decrease in the QoL score of at least five points and compared between the catumaxomab (n = 160) and control (n = 85) groups using the log-rank test and Cox proportional hazards models adjusted for baseline score, country and primary tumour type. Results Deterioration in QoL scores appeared more rapidly in the control than in the catumaxomab group (median 19–26 days versus 47–49 days). The difference in time to deterioration in QoL between the groups was statistically significant for all scores (P < 0.01). The hazard ratios ranged from 0.08 to 0.24 (P < 0.01). Conclusions Treatment with catumaxomab delayed deterioration in QoL in patients with MA. Compared with paracentesis alone, catumaxomab enabled patients to benefit from better QoL for a prolonged survival period. PMID:22734013

    The survival of synchronously growing Ehrlich ascites tumor cells (EAT cells) was measured after x irradiation in various stages of the cell cycle. Cells at the beginning of S or in G2 + M phase showed a high level of killing, whereas cells irradiated in G1 or in the middle of S phase were more resistant. These changes resulted from a change in the survival curve shoulder width (D/sub q/) as cells passed through the cell cycle, and the mean lethal dose (D/sub 0/) remained practically unchanged (0.8 +- 0.05 Gy). When synchronization of the cell population was further sharpened using nocodazole, exponential survival curves were obtained at the beginning of S phase and at mitosis with a D/sub 0/ = 0.8 Gy. When cells (in all stages) were incubated in balanced salt solution for 6 h after irradiation, repair of potentially lethal damage (PLD) was observed, resulting in an increase in D/sub q/, while D/sub 0/ remained constant. Treatment of the cells after irradiation with either caffeine or ..beta..-arabinofuranosyladenine (..beta..-araA) or hypertonic medium resulted in an expression of PLD and reduced the D/sub q/ of the survival curve. We measured the rate of the loss of sensitivity of these treatments that we assume reflects the rate of repair of PLD. Results indicate that the shoulder width D/sub q/ of the survival curve in cells irradiated at various stages of the cell cycle results from repair of PLD. It is suggested that the variations observed in cell survival through the cell cycle might reflect variations in the final amount of PLD either repaired or expressed as the cells progress through stages of the cell cycle.

    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.

    Effects of fixation with glutaraldehyde (GA), glutaraldehyde-osmium tetroxide (GA-OsO4), and osmium tetroxide (OsO4) on ion and ATP content, cell volume, vital dye staining, and stability to mechanical and thermal stress were studied in Ehrlich ascites tumor cells (EATC). Among variables investigated were fixation time, fixative concentration, temperature, osmolality of the fixative agent and buffer, total osmolality of the fixative solution, osmolality of the postfixation buffer, and time of postfixation treatment in buffer (Sutherland, R. M., et al. 1967. J. Cell Physiol. 69:185.). Rapid loss of potassium, exchangeable magnesium, and ATP, and increase of vital dye uptake and electrical conductivity occurred with all fixatives studied. These changes were virtually immediate with GA-OsO4 or OsO4 but slower with GA (in the latter case they were dependent on fixative temperature and concentration) (Foot, N. C. 1950. In McClung's Handbook of Microscopical Technique. 3rd edition. 564.). Total fixative osmolality had a marked effect on cell volume with OsO4 but little or no effect with GA or GA-OsO4. Osmolality of the buffer had a marked effect on cell volume with OsO4, whereas with GA or GA-OsO4 it was only significant at very hypotonic buffer osmolalities. Concentration of GA had no effect on cell volume. Osmolality of the postfixation buffer had little effect on cell volume, and duration of fixation or postfixation treatment had no effect with all fixatives. Freezing and thawing or centrifugal stress (up to 100,000 g) had little or no effect on cell volume after all fixatives studied. Mechanical stress obtained by sonication showed that OsO4 alone produced poor stabilization and that GA fixation alone produced the greatest stabilization. The results indicate that rapid membrane permeability changes of EATC follow fixative action. The results are consistent with known greater stabilizing effects of GA on model protein systems since cells were also rendered relatively

    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.

    In this study we investigated the occurrence of hemorrhages in four groups of electrically stunned broilers, differing with respect to growth rate, age at slaughter, hemodynamic parameters, and ascites mortality. In addition, the effect of three thermal preslaughter conditions on hemorrhage occurrence in thigh and breast muscles was studied. Broilers were either reared at a thermoneutral or low temperature regimen, and were either restricted in their feed consumption or consumed feed ad libitum. Prior to slaughter the broilers were exposed for 2 +/- 0.5 h to either cold (4 +/- 2 C, RH 100%), moderate (19 +/- 2 C, RH: 70 to 80%), or warm (30 +/- 2 C, RH: 60 to 70%) conditions. There was no effect of rearing group, nor was there an interaction between rearing group and preslaughter condition on hemorrhage scores in the thighs or breasts. Preslaughter conditions only affected hemorrhage scores in the left thigh. Scores were highest in broilers exposed to moderate preslaughter conditions. These data indicate that the cause of hemorrhages in muscles is multifactorial. Hemorrhage severity was not diminished in broilers retarded in growth. Pathological hemodynamic adaptations to low rearing temperatures, leading to ascites, did not increase hemorrhage severity, neither upon exposure to moderate nor to cold or warm preslaughter conditions.

    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

    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). As for incidence of AS, there were significant effects of LAT on red blood cell (RBC) count ( P < 0.05), hematocrit (HCT) ( P < 0.05), and the right to total ventricular weight ratio (RV/TV) at 21 days ( P = 0.012) and 28 days ( P = 0.046). Supplementation of DL-HMTBA markedly decreased RV/TV at day 28 ( P = 0.021), RBC (day 21, P = 0.008), HCT (day 21, P < 0.001), mean cell hemoglobin (day 14, P = 0.035; day 21, P = 0.003), and serum protein carbonyl level (day 21, P = 0.009), while significantly increased serum GSH content (day 14, P = 0.022; day 28, P = 0.001), SOD and GSH-Px activities at 21 days of age ( P < 0.001 and P = 0.037). 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 %.

    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].

    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

  12. [Renal and extra-renal mechanisms of sodium and water retention in cirrhosis with ascites].

    PubMed

    Peña, J C

    1995-01-01

    In this work we analyze the renal and systemic factors involved in the sodium retention in two conditions: in extracellular volume depletion and in edema forming states, particularly liver cirrhosis with ascitis. In this paper we accept that the volume loss of body fluids stimulates the "effective arterial blood volume" (VAE). This term results from a decrease in the arterial blood volume secondary to a fall in cardiac output or a peripheral arterial vasodilatation. The reduction in the VAE stimulates: the high pressure baroreceptors (carotid sinus and aortic arch); the intrarrenal mechanisms, such as the yuxtaglomerular apparatus and the renin angiotensin aldosterone system; the sympathetic adrenergic system; the non osmotic release of antidiuretic hormone; prostaglandins (PGE1, Tromboxane) and endothelin; and inhibits the atrial natriuretic peptide. We also describe the sodium transport mechanisms along the nephron during physiological conditions and after volume depletion, and in edema formation states, specially hepatic cirrhosis with ascitis. We speculate that the intrarenal mechanisms are more important and persistent than the systemic mechanisms. It is possible that the sodium retention of these states might be the result of direct stimuli of the tubular sodium transport mechanisms in the different segments of the nephron, mediated by the co and counter transports, ATPase activity or by the second messengers cyclic AMP and cyclic GMP. The clonation and structural characterization of the different sodium transports may help us to establish, more precisely, the intracellular tubular mechanisms responsible for the tendency of the body to retain sodium. The amount of information generated in the future may help us to demonstrate, with more precision, the mechanisms responsible for the sodium retention and excretion in normal and pathological conditions, particularly the edema forming states such as cardiac failure, nephrotic syndrome and hepatic cirrhosis with ascitis.

    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. PMID:27287553

    There is considerable interest in the skin as a site of anti-cancer drug application. Nevertheless, the skin poses a formidable barrier to drug penetration, thereby limiting topical and transdermal bioavailability. However, we previously showed that a thioglycolate-based depilatory agent increases the drug permeability of mouse skin. In the present report, we investigated the skin permeability and efficacy of the anti-cancer drug adriamycin increased when administered transdermally to mice in combination with a thioglycolate-based depilatory agent. Adriamycin in combination with depilatory treatment reduced Ehrlich tumor growth in hairless mice about the weight and size of harvested tumors. In addition, our delivery method for adriamycin increased the therapeutic effectiveness of this agent by decreasing toxicity. Moreover, measurement of adriamycin autofluorescence revealed that topically applied adriamycin penetrate the dermis after depilatory agent treatment. These results indicate that the transdermal delivery of anti-cancer drugs is feasible by handy pretreatment of the skin with a thioglycolate-based depilatory agent. PMID:24300512

    Within the microenvironment, Carcinoma-associated mesenchymal stem cells (Hospicells) are able to influence ovarian tumor development via, among others, the facilitation of angiogenesis in the tumor site allowing an accelerated tumor growth. We demonstrate the presence of a chemotactism between endothelial cells and Hospicells, and a cell line specific increased secretion of pro-angiogenic cytokines such as IL-6, IL-8 and VEGF from ovarian adenocarcinoma cells. Hospicells are also able to attract and activate macrophages to a M2 phenotype and allow them to secrete a huge quantity of pro-angiogenic cytokines, favorable to tumor progression of all the associated ovarian adenocarcinoma cells tested.

    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

    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.

Earlier studies reported that azurin derived from P. aeruginosa and other organisms, showed in vitro and in vivo antitumor properties by the induction of apoptosis. The present study was premeditated to evaluate the in vivo therapeutic efficacy of azurin from P. aeruginosa MTCC 2453 in Dalton's lymphoma (DL) mice model. The acute toxicity assay of azurin showed the 200 μg/kg as sublethal doses in normal mice. The acute toxicity like body weight, peripheral blood cell count, lympho-hematological and biochemical parameters remained unaffected till 200 μg/kg body weight of azurin. The growth inhibitory properties of azurin against in vivo DL model were vastly significant with its sublethal doses. We found that the DL cells survival rate percentage was 29.69, 64.6 and 88.79% in 50, 100 and 200 μg/kg body weight of azurin, respectively. Investigations of the growth inhibitory mechanism in DL cells were exposed by nuclear fragmentation, and the increased accumulation of DL cells in the sub-G₀/G₁ phases in cell cycle analysis are indications of apoptosis. Further, the cause of apoptosis was revealed by Western blot which showed the reduction in the ratio of Bcl-2 and Bax protein expression, the activation of caspases-3 through the release of cytochrome c in DL cells. The survival rate of tumor bearing DL mice treated with azurin analyzed by Kaplan Meir method showed an effective antitumor response as with a dose of 200 μg/kg body weight (an 94.19% increase in life span [ILS] %).

    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

    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. PMID:27493101

    Ethyl pyruvate, an inhibitor of indoleamine 2,3-dioxygenase, slightly suppressed the growth of transplantable Ehrlich tumor in mice and significantly potentiated the therapeutic effect of cyclophosphamide. Another inhibitor amidoxime produced a similar effect. However, both ethyl pyruvate and amidoxime significantly reduced the effect of cycloplatam therapy. The observed changes can be stipulated by different effects of cyclophosphamide and cycloplatam on the subpopulations of lymphoid cells taking part in the formation of antitumor immunity and resistance to tumors.

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.

    Ovarian cancer, a highly metastatic disease, is the fifth leading cause of cancer-related deaths in women. Chickens are widely used as a model for human ovarian cancer as they spontaneously develop epithelial ovarian tumors similar to humans. The cellular and molecular biology of chicken ovarian cancer (COVCAR) cells, however, have not been studied. Our objectives were to culture COVCAR cells and to characterize their invasiveness and expression of genes and proteins associated with ovarian cancer. COVCAR cell lines (n = 13) were successfully maintained in culture for up to19 passages, cryopreserved and found to be viable upon thawing and replating. E-cadherin, cytokeratin and α-smooth muscle actin were localized in COVCAR cells by immunostaining. COVCAR cells were found to be invasive in extracellular matrix and exhibited anchorage-independent growth forming colonies, acini and tube-like structures in soft agar. Using RT-PCR, COVCAR cells were found to express E-cadherin, N-cadherin, cytokeratin, vimentin, mesothelin, EpCAM, steroidogenic enzymes/proteins, inhibin subunits-α, βA, βB, anti-müllerian hormone, estrogen receptor [ER]-α, ER-β, progesterone receptor, androgen receptor, and activin receptors. Quantitative PCR analysis revealed greater N-cadherin, vimentin, and VEGF mRNA levels and lesser cytokeratin mRNA levels in COVCAR cells as compared with normal ovarian surface epithelial (NOSE) cells, which was suggestive of epithelial-mesenchymal transformation. Western blotting analyses revealed significantly greater E-cadherin levels in COVCAR cell lines compared with NOSE cells. Furthermore, cancerous ovaries and COVCAR cell lines expressed higher levels of an E-cadherin cleavage product when compared to normal ovaries and NOSE cells, respectively. Cancerous ovaries were found to express significantly higher ovalbumin levels whereas COVCAR cell lines did not express ovalbumin thus suggesting that the latter did not originate from oviduct. Taken together, COVCAR cell lines are likely to improve our understanding of the cellular and molecular biology of ovarian tumors and its metastasis. PMID:23460878

    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.

    Ascites is a common complication of liver cirrhosis and is associated with a poor prognosis. The main pathophysiology is an increased portal pressure with compensatory activation of neurohumoral systems. A patient history, proper physical exam and adequate examination of ascitic fluid will reveal the aetiology in most cases. Complications such as spontaneous bacterial peritonitis and thrombosis of hepatic vessel should be excluded in cases of first episode of ascites or deterioration of ascites. A moderate salt restriction and treatment with diuretics is the mainstay of treatment. Potentially nephrotoxic drugs such as NSAID and ACE inhibitors should be avoided in patients with cirrhosis.

    The aim of this study was to characterize monocyte-derived macrophages (M-DM) from blood and ascites of cirrhotic patients comparatively with those obtained from blood of healthy controls. The phenotypic profile based on CD14/CD16 expression was analyzed by flow cytometry. Cells were isolated and stimulated in vitro with LPS and heat killed Candida albicans. Phosphorylation of ERK, c-Jun, p38 MAPK, and PKB/Akt was analyzed by Western blotting. A novel CD14(high)CD16(high) M-DM subpopulation is present in ascites (∼33%). The CD14(++)CD16(+) intermediate subset is increased in the blood of cirrhotic patients (∼from 4% to 11%) and is predominant in ascites (49%), while the classical CD14(++)CD16(-) subpopulation is notably reduced in ascites (18%). Basal hyperactivation of ERK and JNK/c-Jun pathways observed in ascites M-DM correlates with CD14/CD16 high expressing subsets, while PI3K/PKB does it with the CD16 low expressing cells. In vitro LPS treatment highly increases ERK1/2, PKB/Akt and c-Jun phosphorylation, while that of p38 MAPK is decreased in M-DM from ascites compared to control blood M-DM. Stimulation of healthy blood M-DM with LPS and C. albicans induced higher phosphorylation levels of p38 than those from ascites. Regarding cytokines secretion, in vitro activated M-DM from ascites of cirrhotic patients produced significantly higher amounts of IL-6, IL-10 and TNF-α, and lower levels of IL-1β and IL-12 than control blood M-DM. In conclusion, a new subpopulation of CD14(high)CD16(high) peritoneal M-DM has been identified in ascites of cirrhotic patients, which is very sensitive to LPS stimulation. PMID:26938502

    We report the case of a 37-year-old man with necrotizing pancreatitis associated with inflammatory extrahepatic portal vein stenosis and progressive ascites. Four months after the acute onset, when no signs of infection were present, portal decompression was performed to treat refractory ascites. Transjugulartranshepatic venoplasty failed to dilate the stenosis in the extrahepatic portion of the portal vein sufficiently. Therefore a Wallstent was implanted, resulting in almost normal diameter of the vessel. In follow-up imaging studies the stent and the portal vein were still patent 12 months after the intervention and total resolution of the ascites was observed.

    Stereoselectivity in the serum binding of flurbiprofen, a non-steroidal anti-inflammatory drug which is highly bound to albumin, was studied in patients with liver and renal disease. Subjects with renal disease or liver disease with ascites had significantly lower serum albumin concentrations than normals, resulting in higher free fractions of both the R(-) and S(+) enantiomers of flurbiprofen as determined by equilibrium dialysis. The ratio (+/- s.d.) of R/S-flurbiprofen free fractions was lower in the subjects with ascites (0.714 +/- 0.298) than in those without ascites (0.796 +/- 0.090) (P < 0.05). PMID:8448071

    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.

    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.

    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. PMID:26997087

    The extravasation of chyle into the peritoneal space usually does not accompany an abrupt onset of abdominal pain with symptoms and signs of peritonitis. The rarity of this condition fails to reach preoperative diagnosis prior to laparotomy. Here, we introduce a case of chylous ascites that presented with acute abdominal pain mimicking peritonitis caused by ovarian torsion in a 41-yr-old female patient with advanced gastric carcinoma. An emergency exploratory laparotomy was performed but revealed no evidence of ovarian torsion. Only chylous ascites was discovered in the operative field. She underwent a complete abdominal hysterectomy and salphingo-oophorectomy. Only saline irrigation and suction-up were performed for the chylous ascites. The postoperative course was uneventful. Her bowel movement was restored within 1 week. She was allowed only a fat-free diet, and no evidence of re-occurrence of ascites was noted on clinical observation. She now remains under consideration for additional chemotherapy.

    Preclinical studies in ovarian cancer have demonstrated upregulation of the Wnt/β-catenin pathway promoting tumor proliferation and chemoresistance. Our objective was to evaluate the effect of the Wnt/β-catenin pathway inhibitor, WNT974, in primary ovarian cancer ascites cells. Ascites cells from patients with papillary serous ovarian cancer were isolated and treated with 1 μM WNT974±100 μM carboplatin. Viability was evaluated with the ATPlite assay. The IC50 was calculated using a dose-response analysis. Immunohistochemistry (IHC) was performed on ascites cells and tumor. Expression of R-spondin 2 (RSPO2), RSPO3, PORCN, WLS, AXIN2, and three previously characterized RSPO fusion transcripts were assessed using Taqman assays. Sixty ascites samples were analyzed for response to WNT974. The ascites samples that showed a decrease in ATP concentration after treatment demonstrated no difference from the untreated cells in percent viability with trypan blue staining. Flow cytometry demonstrated fewer cells in the G2 phase and more in the G1 and S phases after treatment with WNT974. Combination therapy with WNT974 and carboplatin resulted in a higher percentage of samples that showed ≥30% reduction in ATP concentration than either single drug treatment. IHC analysis of Wnt pathway proteins suggests cell cycle arrest rather than cytotoxicity after WNT974 treatment. QPCR indicated that RSPO fusions are not prevalent in ovarian cancer tissues or ascites. However, higher PORCN expression correlated to sensitivity to WNT974 (P=0.0073). In conclusion, WNT974 produces cytostatic effects in patient ascites cells with primary ovarian cancer through inhibition of the Wnt/β-catenin pathway. The combination of WNT974 and carboplatin induces cytotoxicity plus cell cycle arrest in a higher percentage of ascites samples than with single drug treatment. RSPO fusions do not contribute to WNT974 sensitivity; however, higher PORCN expression indicates increased WNT974 sensitivity.

    2016-01-01

    Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment. PMID:27462389

    Background Renal hemodynamic measurements are complicated to perform in patients with cirrhosis; yet they provide the best measure of risk to predict hepatorenal syndrome (HRS). Currently, there are no established biomarkers of altered renal hemodynamics in cirrhosis validated by measured renal hemodynamics. Methods In this pilot study, simultaneous measurements of glomerular filtration rate (GFR), renal plasma flow (RPF), renal resistive indices and biomarkers were performed to evaluate renal hemodynamic alterations in 10 patients with cirrhosis (3 patients without ascites, 5 with diuretic sensitive and 2 diuretic refractory ascites). Results Patients with diuretic refractory ascites had the lowest mean GFR (36.5 ml/min/1.73m2) and RPF (133.6 ml/min/1.73m2) when compared to those without ascites (GFR=82.9 ml/min/1.73m2, RPF=229.9 ml/min/1.73m2) and with diuretic-sensitive ascites (GFR=82.3 ml/min/1.73m2, RPF=344.1 ml/min/1.73m2). A higher mean filtration fraction (FF= GFR/RPF=0.36) was noted among those without ascites compared to those with ascites. Higher FF in patients without ascites is most likely secondary to the vasoconstriction in the efferent glomerular arterioles (normal FF≃0.20). In general, renal resistive indices were inversely related to FF. While patients with ascites had lower FF and higher right kidney main and arcuate artery resistive indices, those without ascites had higher FF and lower right kidney main and arcuate artery resistive indices. While cystatin C and beta-2 microglobulin performed better compared to Cr in estimating RPF; beta-trace protein, beta-2 microglobulin, SDMA, and (SDMA+ADMA) performed better in estimating right kidney arcuate artery resistive index. Conclusion The results of this pilot study showed that identification of non-invasive biomarkers of reduced RPF and increased renal resistive indices can identify cirrhotics at risk for HRS at a stage more amenable to therapeutic intervention, and reduce mortality from kidney

    Various studies have investigated hepatic carcinoma cachexia, however, there is little published information regarding the effect of Chinese Medicine carcinoma cachexia. The present study was performed to investigate the effect of modified Chinese herbal compound jianpijiedu (MJPJD) on a mouse model of ascites-induced hepatic carcinoma cachexia. C57BL/6 mice were randomized to five groups: Control (Group A); xenograft tumor (Group B); low concentration of MJPJD (Group C); high concentration of MJPJD (Group D) and medroxyprogesterone (MPA) combined with indometacin (IND; Group E). The mouse model of ascites-induced hepatic carcinoma cachexia was established by abdominal injection of H22 hepatic carcinoma cells. Subsequently, the body weight, food intake and gastrocnemius weight were recorded, and the levels of interleukin (IL)-lα, IL-6, tumor necrosis factor-α (TNF-α) in ascites were detected by enzyme-linked immunosorbent assay. The protein expression levels of muscle RING-finger protein-1 (MU-RF1) and atrogin 1 were detected by western blotting and immunohistochemistry, and the mRNA levels in gastrocnemius were detected by reverse transcription-quantitative polymerase chain reaction. Compared with the xenograft tumor group, the administration of MJPJD inhibited the increase in body weight and the volume of ascites, the consumption of gastrocnemius was reduced, the net weight of ascites was maintained, the food intake was enhanced and the levels of the cytokines IL-lα, IL-6, TNF-α in ascites and the levels of MU-RF1 and atrogin 1 proteins were reduced. These results indicated that MJPJD delays the pathological process of ascites-induced hepatic carcinoma cachexia, and the mechanism of action may be correlated with a reduction in the levels of IL-lα, IL-6, TNF-α and inhibiting the activation of the ubiquitin proteosome pathway.

    The hyperdynamic circulation of cirrhosis participates in the pathophysiology of portal hypertension. P450-dependent epoxyeicosatrienoic acids (EET) are potent vasodilators. We evaluated plasma levels of EETs in cirrhotic patients and the effect of epoxygenase and nitric oxide synthase (NOS) inhibition on skin blood flow, measured by laser Doppler flowmetry, in normal subjects and cirrhotic patients with and without ascites. Free plasma EETs were increased in cirrhotic patients compared to normal subjects, while the ratio between 8,9-, 11,12-, and 14-15-EET was the same. In cirrhotic patients without ascites, skin blood flow was significantly increased compared to normal subjects. In patients with ascites skin blood flow was significantly reduced compared to control subjects and patients without ascites. Inhibition of epoxygenase with miconazole and of NOS with L-NG-Nitroarginine methyl ester (L-NAME) decreased basal skin flow in normal subjects and in cirrhotic patients, the effect being higher in cirrhotic patients. Miconazole caused a further decrease in flow when administered with L-NAME, both in normal subjects and in cirrhotic patients. In conclusion, EETs participate in the control of peripheral circulation of normal subjects and in the pathophysiology of peripheral vasodilatation of cirrhotic patients with ascites. PMID:22245571

    To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.

    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

    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.

    This study revisited 18F-fluorodeoxyglucose (18F-FDG) uptake and its relationship to hypoxia in various tumor models. METHODS: We generated peritoneal carcinomatosis and subcutaneous xenografts of colorectal cancer HT29, breast cancer MDA-MB-231, and non–small cell lung cancer A549 cell lines in nude mice. The partial oxygen pressure (pO2) of ascites fluid was measured. 18F-FDG accumulation detected by digital autoradiography was related to tumor hypoxia visualized by pimonidazole binding and glucose transporter-1 (GLUT-1) in frozen tumor sections. RESULTS: Ascites pO2 was 0.90 ± 0.53 mm Hg. Single cancer cells and clusters suspended in ascites fluid as well as submillimeter serosal tumors stained positive for pimonidazole and GLUT-1 and had high 18F-FDG uptake. In contrast, 18F-FDG uptake was significantly lower in normoxic portion (little pimonidazole binding or GLUT-1 expression) of larger serosal tumors or subcutaneous xenografts, which was not statistically different from that in the liver. CONCLUSIONS: Glucose demand (18F-FDG uptake) in severely hypoxic ascites carcinomas and hypoxic portion of larger tumors is significantly higher than in normoxic cancer cells. Warburg effect originally obtained from Ehrlich ascites carcinoma may not apply to normoxic cancer cells. Our findings may benefit the better understanding of 18F-FDG PET in oncology application.

    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

    Spontaneous bacterial peritonitis (SBP) rarely presents as pneumoperitoneum. Only four such cases have been reported in the English literature. This report concerns a 65 year-old male patient with SBP and pneumoperitoneum. He has had a history of peptic ulcer. However, upon examination, no associated diseases or compromised immunity was detected. He presented with acute abdominal pain and subphrenic free air. An emergency laparotomy was performed, under the impression of a perforated peptic ulcer. Yet, no intraabdominal pathology except 200 ml of purulent ascites was found. The ascites culture yielded E. coli, B. fragilis, and P. aeruginosa confirming the diagnosis of SBP. Antibiotics which are sensitive to gas-forming bacteria should be prescribed before the result of the ascites culture is known. PMID:7834563

    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.

    Pseudo-Meigs' syndrome associated with colorectal cancer is extremely rare. We report here a case of pseudo-Meigs' syndrome secondary to metachronous ovarian metastases from colon cancer. A 65-year-old female with a history of surgery for transverse colon cancer and peritoneal dissemination suffered from metachronous ovarian metastases during treatment with systemic chemotherapy. At first, neither ascites nor pleural effusion was observed, but she later complained of progressive abdominal distention and dyspnea caused by rapidly increasing ascites and pleural effusion and rapidly enlarging ovarian metastases. Abdominocenteses were repeated, and cytological examinations of the fluids were all negative for malignant cells. We suspected pseudo-Meigs' syndrome, and bilateral oophorectomies were performed after thorough informed consent. The patient's postoperative condition improved rapidly after surgery. We conclude that pseudo-Meigs' syndrome should be included in the differential diagnosis of massive or rapidly increasing ascites and pleural effusion associated with large or rapidly enlarging ovarian tumors.

    Chylothorax and chylous ascites are an accumulation of fluid containing a large proportion of triglycerides. The presence of these two effusions simultaneously is rare. A case of a patient with a known history of cirrhosis, hospitalized for an ascetic decompensation with left pleural effusion is herein presented. The woman was diagnosed as presenting both chylous ascites and chylothorax. Both fluids are transudate type fluids. After evacuation of the fluids and implementation of an adapted treatment neither effusion reappeared. The patient has been followed for the past year and has not shown any signs of relapse. Chylothorax, in cirrhotic patients is due to trans-diaphragmatic passage of fluid originating from the chylous ascites. Both extravasations have the same biological characteristics. PMID:16449926

    The most common properties of oncogenes are cell proliferation and the prevention of apoptosis in malignant cells, which, as a consequence, induce tumor formation and dissemination. However, the effects of oncogenes on the tumor microenvironment (TME) have not yet been examined in detail. The accumulation of ascites accompanied by chronic inflammation and elevated concentrations of VEGF is a hallmark of the progression of ovarian cancer. We herein demonstrated the mechanisms by which oncogenes contribute to modulating the ovarian cancer microenvironment. c-MYC and KRAS were transduced into the mouse ovarian cancer cell line ID8. ID8, ID8-c-MYC, or ID8-KRAS cells were then injected into the peritoneal cavities of C57/BL6 mice and the production of ascites was assessed. ID8-c-MYC and ID8-KRAS both markedly accelerated ovarian cancer progression in vivo, whereas no significant differences were observed in proliferative activity in vitro. ID8-KRAS in particular induced the production of ascites, which accumulated between approximately two to three weeks after the injection, more rapidly than ID8 and ID8-c-MYC (between nine and ten weeks and between six and seven weeks, respectively). VEGF concentrations in ascites significantly increased in c-MYC-induced ovarian cancer, whereas the concentrations of inflammatory cytokines in ascites were significantly high in KRAS-induced ovarian cancer and were accompanied by an increased number of neutrophils in ascites. A cytokine array revealed that KRAS markedly induced the expression of granulocyte macrophage colony-stimulating factor (GM-CSF) in ID8 cells. These results suggest that oncogenes promote cancer progression by modulating the TME in favor of cancer progression. PMID:27483433

Focus is on the regulatory volume decrease (RVD) that occurs after cell swelling, the volume regulatory ion channels involved, and the mechanisms (cellular signalling pathways) that regulate these channels. Finally, I shall also briefly review current investigations in these two cell lines that focuses on how changes in cell volume can regulate cell functions such as cell migration, proliferation, and programmed cell death.

    One month after onset of an acute biliary pancreatitis, a 75-year-old man developed refractory ascites. Duplex ultrasound and CT scan revealed a focal stenosis of the extrahepatic portal vein as confirmed by transhepatic direct portography. In the same session, this stenosis, responsible for symptomatic prehepaticportal hypertension, was successfully dilated and stented and afterwards a residual pressure gradient of 1 mmHg over the stented segment was measured. One week after the stenting procedure the patient was free of ascites and control physical and biochemical examination one year later is completely normal.

    The article presents the results of investigation of antitumor properties of platinum-arabinogalactan complex. We showed the ability of the complex to inhibit the growth of Ehrlich ascites tumor cells. It is found that the distribution of the platinum-arabinogalactan complex is not specific only for tumor cells in mice. The complex was found in all tissues and organs examined (ascites cells, embryonic cells, kidney, and liver). The mechanism of action of the arabinogalactan-platinum complex may be similar to cisplatin as the complex is able to accumulate in tumor cells. PMID:27193706

    Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome known as exomphalos-macroglossia - gigantism syndrome. Prognosis is good, prenatal diagnosis is important for pregnancy management but might be difficult due to clinical overlap with other syndromes. Perlman syndrome is an overgrowth syndrome with high perinatal mortality, most frequent antenatal findings include polyhydramnios, macrosomia, visceromegaly, nephromegaly and foetal ascites. Authors present a case of prenatally diagnosed BWS with severe ascites as first antenatal finding and lethal course, signs more typical of Perlman syndrome. This combination of clinical signs has not been published yet and may contribute to specification of possible prenatal manifestation of BWS. PMID:24215131

    Using the model of breast cancer Ehrlich ascites tumor in mice, we showed that a sigle intraperitoneal injection of cardiac glycoside digoxin 1 h before the intraperitoneal injection of cisplatin increased the anticancer effect of the cytostatic drug more than twice when recalculated for the dose. It is assumed that the modifying effect of digoxin is determined by the direct inhibition of glycolysis in tumor cells. Taking into account the design of the study, we consider promising the clinical evaluation of the effectiveness of digoxin as a modifier of cisplatin efficiency in intracavitary therapy of ascites cancers with pleural and abdominal dissenmination.

    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.

    The tridentate complex CuGHK does not form ESR detectable adducts upon addition to either glutathione or Ehrlich ascites cells under our conditions. The absence of adducts is consistent with the poor uptake of CuGHK by cells. ESR spectra are used to characterize adduct formation between CuGHK and histidine. The CuGHK-histidine adduct is not stable in the presence of Ehrlich ascites tumor cells. It is argued that a Cu(His)2 complex is formed as a consequence of the interaction of GHK with cells.

    Decompensation of cirrhosis presents with ascites, encephalopathy, variceal bleeding, or spontaneous bacterial peritonitis. Infrequently, decompensation can result from spontaneous bacterial empyema. A 38-year-old man presented with fevers, chills, and dyspnea. Labs were significant for leukocytosis, transaminitis, and coagulopathy. Imaging showed liver cirrhosis with ascites and a left pleural effusion. Treatment of the effusion consisted of chest tube drainage and antibiotics. Spontaneous bacterial empyema was diagnosed after pleural fluid cultures were positive for Escherichia coli. Our case demonstrates that spontaneous bacterial empyemas can be left-sided, and the first sign of decompensation. PMID:26958567

    The ultrasound examination of 29 children, aged between 2 to 13 years with clinical and serological proven dengue haemorrhagic fever were reviewed and correlated with the findings in the literature. Ultrasound findings consisted of: (1) ascites, (2) pleural effusion, (3) abnormal gallbladder wall and (4) abnormal liver parenchyma. Ascites is common in DHF. Pleural effusion was found on the right and on bilateral pleural spaces. There was no isolated left pleural effusions. The abnormal gallbladder wall has never been mentioned before in the literature and the abnormal liver parenchyma might be due to intraparenchymal and subcapsular haemorrhages.

    Six new organometallic derivatives of Rh(I), belonging to the general structure [Rh(CO)2(L)(Cl)], were synthesized and characterized by chemical analysis and IR determinations. The following ligands (L) were employed: 2-aminothiazole, thiazole, 2-amino-6-bromobenzothiazole, 5-chloro-2-methylthiobenzothiazole, 2-bromo-thiazole, and 2-isopropylthiazole. These new complexes were assayed in vitro with KB cells and in vivo with mice bearing established P388 and L1210 leukemias. Assays against S180 and Ehrlich ascitic tumors were also performed. Two complexes displayed antitumor activity against ascitic tumors.

    Non-Hodgkin’s lymphoma (NHL) can commonly present as chylothorax and rarely as chylopericardium. Here we are presenting a case of a 21-years-old female with bilateral chylothorax, chylopericardium and chylous ascites all together finally diagnosed to have NHL as the etiology. To the best of our knowledge, it has been reported very infrequently. PMID:21712926

    We experienced a case of pseudo-Meigs syndrome associated with metachronous metastasis to the ovary from ascending colon cancer. A 65-year-old woman underwent curative surgery for ascending colon cancer at another hospital. A follow-up CT carried out 3 months after the surgery revealed a right ovarian tumor and a large amount of ascites. The patient was diagnosed with ovarian metastasis from ascending colon cancer with carcinomatous peritonitis. Palliative care was recommended, and she presented at our department for a second opinion. In spite of a large amount of ascites and pleural effusion, no disseminating tumor was detected on contrast-enhanced CT at our hospital, and we recommended that she undergo a diagnostic laparotomy. The laparotomy was negative for carcinomatous peritonitis and a right oophorectomy was performed. The histopathological findings indicated that the ovarian tumor was consistent with metastasis from ascending colon cancer. After the surgery, we initiated chemotherapy with mFOLFOX6+bevacizumab and the symptoms were well controlled. A follow-up CT carried out 11 months after the surgery revealed a left ovarian tumor and increased ascites, and the patient underwent a left oophorectomy. Then, chemotherapy with the same regimen was administered for 12 months, and she did not develop any signs of recurrence for 27 months after the surgery. Ovarian metastasis from colon cancer may occasionally cause pseudo-Meigs syndrome, and it is important to be aware of the usefulness of oophorectomy for the control of ascites and pleural effusion.

    Endometrial implantation is the major cause of endometriosis (EMS). Matrix metalloproteinase (MMPs) can degrade multiple extracellular matrix and has been postulated to be related with EMC occurrence. This study thus investigated serum and ascites levels of MMP-9 in EMS patients, in an attempt to discuss the correlation between MMP-9 and EMS. A total of 100 EMS patients, including eutopic endometrium and ectopic endometrium, were recruited in this study along with hysteromyoma patients as the control group. Peripheral blood and ascites samples were collected and tested for MMP-9 levels using gelatin zymogram and enzyme-linked immunosorbent assay (ELISA). In EMS patients, MMP-9 levels in serum and ascites were 6.24 ± 0.53 mM and 38.57 ± 4.93 mM, respectively. Both of them were significantly higher than those in control group (P<0.05). Eutopic endometrium group had higher MMP-9 levels compared to those in ectopic endometrium ones (P<0.05). With advancement of disease stage, EMS patients had progressively elevated MMP-9 levels (P<0.05). Patients at proliferative stage had higher MMP-9 secretion (P<0.05). In summary, site of endometrium, clinical stage and proliferative cycle were independent risk factors for EMS. The elevation of serum and ascites MMP-9 existed in EMS patients, of which those had ectopic endometrium, advanced stage and at proliferative stage had higher MMP-9 expression. PMID:26722547

    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

    2016-08-01

    The objective of the present study was to investigate the effects of different levels of copper (as supplemental copper-methionine) on ascites incidence and matrix metalloproteinase-2 (MMP-2) changes in the lungs of cold-stressed broilers. For this purpose, 480 1-day-old Ross 308 broiler chickens were randomly assigned to six treatments. Treatments consisted of two ambient temperatures (thermoneutral and cold stress) each combined with 0, 100, and 200 mg supplemental copper/kg as copper-methionine in a 2 × 3 factorial arrangement in a completely randomized design with four replicates. Ascites was diagnosed based on abdominal and pericardial fluid accumulation at 45 days of age. Fourty-eight broilers were killed at 38 and 45 days of age, and their lungs were collected for biological analysis. Results showed that MMP-2 increased in the lungs of ascitic broilers and that copper-methionine supplementation significantly reduced MMP-2 in cold-stressed broiler chickens. Treatments did not affect tissue inhibitor of metalloproteinase-2 (TIMP-2) at 38 and 45 days of age, and no difference was observed between 100 and 200 mg/kg copper-methionine treatments. In conclusion, copper-methionine at higher than conventional levels of supplementation decreased ascites incidence in low temperature through reduced MMP-2 concentration. Further research is warranted to investigate the effect of copper on MMP-2 concentrations in other tissues with high oxygen demand. PMID:26749413

    1981-01-01

    When the clonogenic survival of mouse haemopoietic stem cells (CFU-S) and leukaemia L1210 cells growth as ascites tumours are compared after being heated in vitro and assayed in vivo by spleen-colony assay, there is no significant difference in the terminal slopes of the survival curves. The shoulders of the survival curves differ, but this may be explained by differences in cell kinetics. By contrast, L1210 leukaemic marrow cells are considerably more susceptible to the lethal effects of hyperthermia (43 degrees C) than either normal marrow stem cells or L1210 leukaemic cells grown as ascites tumours. Moreover, the killing of L1210 ascites cells by hyperthermia can be enhanced by heating L1210 ascites cells with an equal number of normal marrow cells, or as upernatant removed from heated marrow cells. Most cells in lukaemic marrow are normal, and it is postulated that the increased thermal sensitivity of L1210 cells in leukaemic marrow is caused by diffusible factors (e.g. lysosomal enzymes) released by heating normal marrow cells.

    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

    Predicting the presence and the grade of varices by non-invasive methods is likely to predict the need for prophylactic beta blockers or endoscopic variceal ligation. The factors related to the presence of varices are not well-defined. Therefore, the present study has been undertaken to determine the appropriateness of the various factors in predicting the existence and also the grade of esophageal varices. Patients with diagnosis of liver cirrhosis due to hepatitis C or B were included in a retrospective study between January 2001 and January 2010. All the patients underwent detailed clinical evaluation, appropriate investigations, imaging studies (ultrasound with Doppler) and endoscopy at our center. Five variables considered relevant to the presence and grade of varices were tested using univariate and multivariate analysis (logistic regression). Three hundred and seventy two patients with viral liver cirrhosis were included, with 192 (51.6%) males. Platelet count and abundance of ascites were significantly associated with the presence of esophageal varices. However, abundance of ascites, prothrombin time, diameter of the spleen and portal vein were significantly associated with a large varice. In multivariate analysis, platelet count inferior to 100000 was associated with presence of varices (p = 0.04) and only abundance of ascites was associated with large varice. Low Platelet count (< or equal 100000) is associated with the presence of varices in viral cirrhotic patients and abundance of ascites is correlated with the presence of large varices.

    The conventional method of ascitic fluid culturing was compared with the bedside inoculation of ascites into blood culture bottles and into lysis-centrifugation tubes. The conventional culture method was compared with the blood culture bottle method in 31 episodes of spontaneous bacterial peritonitis (SBP). Cultures were positive with the conventional culture method in 11 (35%) episodes and with the blood culture bottle method in 26 (84%) episodes (P less than 0.001). The lysis-centrifugation tube method was compared with the blood culture bottle method in 24 episodes of SBP. Cultures were positive with the lysis-centrifugation tube method in 11 (46%) episodes and with the blood culture bottle method in 19 (79%) episodes (P less than 0.05). Moreover, the blood culture bottle method also shortened the time needed for the detection of bacterial growth. In conclusion, bedside inoculation of ascites into blood culture bottles should be used routinely for patients with suspected SBP. Culturing of ascites in lysis-centrifugation tubes is more laborious than and inferior to that in blood culture bottles. PMID:1551984

Serum CA-125 was significantly elevated in BCS patients compared to healthy volunteers (P < 0.001). Higher levels of CA-125 were found in BCS patients with abnormal hepatic function and low serum albumin levels and in patients with high volume of ascites compared to patients without these abnormalities. Serum CA-125 levels significantly correlated with ascites volume, serum level of alanine aminotransferase, aspartate aminotransferase, albumin, and Rotterdam BCS scores. The follow-up study indicated that the survival rate and asymptomatic survival rate after interventional treatment were lower in BCS patients with serum CA-125 > 175 U/mL (P < 0.05). Conclusion. Serum CA-125 was significantly higher in patients with primary BCS and had a positive correlation with the volume of ascites, severity of liver damage, and poor prognosis. Thus the serum CA-125 levels may be used to estimate the severity and prognosis of BCS in Chinese patients. PMID:26451141

We present a case in which the leakage of chylous fluid and then a para-aortic lymphocyst followed right nephrectomy and para-aortic node dissection for kidney cancer. Our method of treatment utilized conservative management of chylous ascites and laparoscopic internal drainage of the retroperitoneal lymphocyst.

    Thirty-four adult patients with portomesenteric venous occlusion (PVO) were reviewed. In 11 with hepatic cirrhosis, PVO was usually heralded by worsening ascites often with varix hemorrhage; mortality was high. Four with isolated portal block had varix hemorrhage without ascites. All of these patients survived despite recurrent hematemesis when portal decompression was not feasible in two patients. Eight others (5 agnogenic and 3 with hypercoagulability), experienced sudden abdominal pain with a clot typically propagated into mesenteric tributaries with ileojejunal infarction; survival was related to the promptness of operation and the extent of bowel ischemia. Of five patients with intraabdominal sepsis and pylephlebitis, only one survived. In the final six patients, PVO occurred with intraabdominal carcinoma. Five had progressive ascites, cachexia, and an early death. Imaging techniques included plain and contrast roentgenograms, ultrasonography, and for definitive diagnosis direct portography (operative or splenoportogram), indirect portography (splanchnic arteriovenogram), and computed tomography. Thirteen of 34 patients had ascites, and in nine of 11 patients examined, protein concentration of ascitic fluid was extremely low (less than 0.6 g/dl). Clinical presentation of PVO varies, depending on acuteness and extent of visceral venous blockade, severity of portal hypertension, auxiliary venous collateralization, and regional lymph flow. Inciting factors include endothelial damage and blood hypercoagulability from trauma, infection, stagnant circulation, blood dyscrasia, and malignancy. Improved imaging now allows early diagnosis.

    The objective of this study was to evaluate the pathogenesis of ascites in mice infected with Toxoplasma gondii and gerbils infected with Neospora caninum during the acute phase disease. For that, 12 gerbils [Experiment I: not infected/control (n=6) and infected (n=6)] and 12 mice [Experiment II: control (n=6) and infected (n=6)] were used. Infected gerbils and mice showed marked ascites on days 5-7 post-infection (PI), while the not-infected animals had not ascites. Peritoneal liquid was collected from the all mice with uninfected animals receiving 1.5mL of saline solution into their abdominal cavity, allowing the recovery of cavity liquid. As a result, it was possible to observe differences in physics, chemistry and cytological analysis of the fluid cavity of animals infected with N. caninum and T. gondii, when they were compared with uninfected animals, as well as between animals experimentally infected. Additionally both, N. caninum and T gondii, caused an increase in the levels of nitric oxide (NOx-nitrate/nitrite), protein oxidation (AOPP) and lipid peroxidation (TBARS), while serum total protein and albumin were reduced in infected gerbils and mice. Gerbils infected with N. caninum showed multiple large cells with multilobulated nucleus, lytic necrosis and abundant amount of eosinophilic cytoplasm into the hepatic parenchyma. By the other hand, mice infected with T. gondii developed myriad foci of lytic necrosis combined with tachyzoites and cysts containing bradyzoites in liver. Both experimental models for N. caninum and T. gondii showed inflammatory foci and tachyzoites the peritoneum, which could be a major cause of ascites. Toxoplasmosis and neosporosis were able to cause clinical signs in experimental models with similar alterations in peritoneal fluid; however the toxoplasmosis histological changes were much more evident. Therefore, the pathogenesis of ascites appears to be directly related to liver damage, which strongly suggests alteration in the

    AIM: To investigate changes over time in, and effects of sealing technology on, milk test results following pancreatectomy. METHODS: From April 2008 to October 2013, 66 pancreatic resections were performed at the Iwakuni Clinical Center. The milk test has been routinely conducted at the institute whenever possible during pancreatectomy. The milk test comprises the following procedure: A nasogastric tube is inserted until the third portion of the duodenum, followed by injection of 100 mL of milk through the tube. If a chyle leak is present, the patient tests positive in this milk test based on the observation of a white milky discharge. Positive milk test rates, leakage sites, and chylous ascites incidence were examined. LigaSure™ (LS; Covidien, Dublin, Ireland), a vessel-sealing device, is routinely used in pancreatectomy. Positive milk test rates before and after use of LS, as well as drain discharge volume at the 2nd and 3rd postoperative days, were compared retrospectively. Finally, positive milk test rates and chylous ascites incidence were compared with the results of a previous report. RESULTS: Fifty-nine milk tests were conducted during pancreatectomy. The positive milk test rate for all pancreatectomy cases was 13.6% (8 of 59 cases). One case developed postoperative chylous ascites (2.1% among the pancreatoduedenectomy cases and 1.7% among all pancreatectomies). Positive rates by procedure were 12.8% for pancreatoduodenectomy and 22.2% for distal pancreatectomy. Positive rates by disease were 17.9% for pancreatic and 5.9% for biliary diseases. When comparing results from before and after use of LS, positive milk test rates in pancreatoduodenectomy were 13.0% before and 12.5% after, while those in distal pancreatectomy were 33.3% and 0%. Drainage volume tended to decrease when LS was used on the 3rd postoperative day (volumes were 424 ± 303 mL before LS and 285 ± 185 mL after, P = 0.056). Both chylous ascites incidence and positive milk test rates

    AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation. METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index (BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease (MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure (MIP) and maximal expiratory pressure, spirometry, root mean square (RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference (P = 0.01) between the first (initial) and the third month (final) MIP in the control group and in the intervention group, but there was no difference (P = 0.45) between the groups. The RMS of the diaphragm was lower (P = 0.001) and the functional capacity was higher (P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group (P = 0.01) and the intervention group (P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group (P = 0.083) and intervention group (P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups (P = 0.21). In the intervention group, patients with

    Seventeen year old girl, a known case of Wilson disease presented to us with a non-healing skin ulcer followed by appearance of jaundice, ascites and progressive fatigue of 1 month duration. She was diagnosed to have Wilson disease 5 years back and had been well controlled on d-penicillamine. On enquiry, she was found to be noncompliant with her medication in the preceding 6 months. On examination, she had severe pallor, icterus with moderate ascites and oedema feet. Investigations revealed severe haemolytic anemia and deranged liver function. The lesion was diagnosed to be pyoderma gangrenosum on skin biopsy. The appearance of a cutaneous lesion followed by deterioration in the liver disease and hemolysis suggested uncontrolled Wilson disease as the triggering factor. Chelation therapy improved her haemoglobin and liver function as well as led to healing of the ulcer. We describe pyoderma gangrenosum as a new manifestation of Wilson disease.

    Bowel endometriosis affects 3-37% of patients with endometriosis, involving more frequently the rectum and the rectosigmoid junction. Severe endometriosis with bowel involvement is often refractory to standard medical therapy. For these reasons, surgery for bowel treatment is frequently needed. We report the case of a 36-year-old woman with deep endometriosis of the pelvis, triple segmental bowel involvement (recto-sigma, ileum-cecum, transverse colon) and massive endometriotic ascites with secondary Glisson's capsule inflammation, refractory to medical therapy. A laparoscopic triple segmental bowel resection and complete fertility sparing excision of pelvic endometriotic lesions was performed. At 48 months of follow-up, the woman was asymptomatic, with no evidence of recurrence of disease or ascites. Laparoscopic segmental bowel resection, including multiple section, is feasible in selected symptomatic patients with consequent improved quality of life, morbidity rates similar to those achieved by laparotomy and with a less detrimental effect on fertility.

    Chylous ascites and coexistent chylothorax is a rare but important complication following retroperitoneal abdominal surgery. We report a 70-year-old male who developed gradual abdominal distension, chest tightness, and dyspnea five months after having an uncomplicated aortobifemoral bypass performed. Physical examination was consistent with a large right sided effusion and ascites which were confirmed by computed tomography. Thoracentesis yielded an opaque milky fluid with analysis consistent with a chylothorax with a paracentesis revealing fluid that was similar in both appearance and biochemistry. The patient failed initial conservative management so a chest tube was placed followed by chemical pleurodesis. We review the literature of the pathophysiology and treatment approach to such a pleural effusion. PMID:26635989

    Patient: Female, 75 Final Diagnosis: Ovarian teratoma Symptoms: Chronic pelvic pain Medication: — Clinical Procedure: Tumor resection Specialty: Oncology Objective: Rare disease Background: Struma ovarii is a rare ovarian teratoma with non-specific clinical presentation that can mimic malignancy, especially when combined with the presence of ascites. Since the surgical procedures performed for benign and malignant tumors are quite different, pre-operative differential diagnosis is key. In this case report we compare the levels of biomarkers CA 125 and HE4 in the differential diagnosis of a suspicious ovarian tumor. Case Report: A 75-year-old woman with a palpable mass at the left adnexa, ascites, and high levels of CA 125, underwent a subtotal abdominal hysterectomy and bilateral salpingo-oophorectomy. Histology reported benign struma ovarii. Conclusions: Even though transvaginal ultrasound and CA 125 levels suggested malignancy, HE4 measurements correctly diagnosed benignity. PMID:27381498

    The clinical signs of tansy ragwort poisoning are variable and in 5 cases included diarrhea, tenesmus, ascites, bloody feces, icterus, paresis, CNS involvement, rectal prolapse, poor appetite and weight loss. It is thus apparent that the disease can be confused clinically with many others, and tansy ragwort poisoning should be considered in animals exhibiting ascites, diarrhea and rectal prolapse. Several cases of tansy ragwort (Senecio jacobaea) poisoning occurring from 1969 to 1976 are reported to illustrate the numerous clinical pictures that might confront a practitioner. The disease is sporadic in this area. The poisonous principles in tansy ragwort are pyrrolizidine alkaloids, which cause gradual alteration and necrosis of liver cells with replacement by fibrous tissue. The development of signs in all of these cases could be attributed to failure of one or more liver functions.

    Eighteen patients with 21 serious infections were treated with ceftriaxone, 1 g intravenously every 12 h, for a mean duration of 8 days. Eighteen gram-negative and two gram-positive organisms were isolated. Sites of infection included blood (three patients), urinary tract (six patients), respiratory tract (seven patients), biliary tract (three patients), ascitic fluid (one patient), and skin (one patient). Serum, bile, and ascitic fluid concentrations of ceftriaxone were in excess of the minimal bactericidal concentration required for the infecting organism in all cases. A bacteriological response was demonstrated in 94% of the infections. A clinical response occurred in four infections from which no pathogens were recovered. In one patient, ceftriaxone failed to eradicate a peritoneal infection due to Bacteroides fragilis. In two patients, superinfection with enterococci developed both during and after therapy. Systemic tolerance to ceftriaxone was excellent. PMID:6289735

    Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

    An extract of Ruta graveolens was found to be cytotoxic to Dalton's lymphoma ascites (DLA), Ehrlich ascites carcinoma (EAC) and L929 cells in culture (IC100=16 mg/ml) and also to increase the lifespan of tumour bearing animals. The extract further decreased solid tumours developing from DLA and EAC cells when given simultaneously with elongation of the lifespan of tumour-bearing animals. A homeopathic preparation of Ruta graveolens (200 c) was equally effective. Neither was effective for reducing already developed tumours. The Ruta graveolens extract was found to scavenge hydroxyl radicals and inhibit lipid peroxidation at low concentrations. However, at higher concentrations the extract acted as a prooxidant as inhibition of lipid peroxidation and scavenging of hydroxyl radical was minimal. These data indicates that the prooxidant activity of Ruta graveolens may be responsible for the cytocidal action of the extract and its ability to produce tumour reduction.

    1976-08-01

    In order to clarify the mechanism of potentiation of cyclophosphamide activity by centrophenoxine, blood concentration of total and activated cyclophosphamide was examined. Blood concentration of cyclophosphamide increased by the compound and biological half-life of activated cyclophosphamide was markedly increased to 30 min from 18 min in intraperitoneal administration. At the same time, concentration of active form in ascites fluid was also increased and biological half-life of the active form was increased to 50 min from 18 min. Similar increase in blood level of active form was also shown by p-chlorophenoxyacetic acid and probenecid, but concentrations at early stages after injection was not increased. As a result, potentiation of cyclophosphamide activity by centrophenoxine was found to be due to maintenance of active form in both blood and ascites fluid at higher levels than those in the control.

    The multivariant approach offers best possibilities for assessment of liver function. The role of the different clinical, clinico-laboratory and combined clinical and clinicochemical indices in the prognosis of liver cirrhosis was studied in patient in ambulatory conditions. A step regressive mathematical model with the help of the program 2R of the statistical package BMDP was used. The regression of the clinical indices by 5 steps of the mathematical model showed that of greatest importance for the survival are the following indices: ascites, months since its onset, collaterals, anorexia and vascular nevi. By 4 steps of the regressive model of the clinico-chemical indices the following indices were chosen: prothrombin time, albumin, total bilirubin, cholesterol and alkaline phosphatase. The regression of the combined clinical and clinico-chemical indices pointed out as basic factors 3 clinical indices (ascites, months since its onset, collaterals) and 3 clinico-chemical indices related to the disturbed liver function (prothrombin time, total bilirubin, albumin).

    A monoclonal antibody was used for the localization of the nuclear T3 receptor in different tissues of the adult rat: the liver, kidney, heart, lung, spleen, testis, and pituitary. In the liver, the immunoreactivity was found uniformly distributed in the nuclei of hepatocytes. Sections incubated with a control ascitic fluid or with the same ascitic fluid pre-adsorbed with purified receptor showed no specific staining. In the kidney, the immunoreactivity was higher in the epithelial cell of the proximal convoluted tubes and juxtaglomerular cells. In the heart, only the myocardial cells were stained. In the lung, the immunoreactivity was confined to type II pneumocytes and alveolar macrophages. In the spleen, only a few mature lymphocyte and macrophage cell nuclei were stained. These results show that: 1) the abundance of the nuclear T3 correlates with previous studies using hormone binding techniques; 2) the nuclear T3 receptor is selectively located in certain cell types, which possess a precise local function.

    Tuberculous peritonitis is a common form of abdominal tuberculosis and is frequently associated with liver disease. Diagnosis of this disease presents a diagnostic dilemma and the presence of liver cirrhosis further confounds the clinical picture. Moreover, the co-existence of these two diseases casts doubt on the validity of various diagnostic tests available. The interpretation of tests of ascitic fluid analysis becomes questionable despite the fact that peritoneal tuberculosis and liver disease cause ascites to develop through separate mechanisms. In addition, the treatment of tuberculosis mandates a better understanding of the co-existent disease in view of the potential hepatotoxicity of anti-tuberculous medication. This review aims to address the prevalence of coexistent liver disease in patients with tuberculous peritonitis, the diagnostic difficulties posed by such and the various treatment approaches to be adopted.

    A 10-year-old Swiss Braunvieh cow near term was referred to our clinic because of severe abdominal distension, which caused loss of demarcation between the udder and ventral abdominal wall. Ultrasonographic examination revealed marked ascites and multiple echogenic nodules in the greater omentum. Based on the findings, non-inflammatory ascites attributable to neoplasia was diagnosed. Rupture of the prepubic tendon from the pubic symphysis was also suspected. Because of a grave prognosis, parturition was induced and a live calf was delivered. The cow was euthanized and a postmortem examination was carried out. The abdominal cavity contained 248.5 litres of clear fluid. The greater omentum was thickened and oedematous and regionally contained fluid-filled cystic structures, which varied in size with a maximum diameter of 10 centimetres. Based on the histological, immunohistochemical and electron microscopical findings, biphasic mesothelioma with cyst formation affecting the entire abdominal cavity was diagnosed.

    Lymphangiography and thoracic duct embolization are well-described techniques for the diagnosis and treatment of thoracic lymphatic leaks refractory to conservative treatment. However, thoracic duct embolization is not an option in patients with abdominal chylous leaks. The present report describes a 68-year-old man who underwent an aortomesenteric bypass complicated by a high-output postoperative chylothorax (>2,000 ml/day) and chylous ascites (>7,000 ml/paracentesis). Ultrasound-guided intranodal lymphangiography demonstrated a retroperitoneal lymphatic leak tracking along the vascular graft into the peritoneal cavity. Computed tomography-guided lymphatic duct occlusion with N-butyl cyanoacrylate glue was performed, resulting in successful treatment of both chylothorax and chylous ascites.

    Struma ovarii is an uncommon ovarian teratoma comprised predominantly of mature thyroid tissue. The combination of pseudo-Meigs’ syndrome, and elevation of CA 125 to the struma ovarii is a rare condition that can mimic ovarian malignancy. We reported a case of benign struma ovarii, presenting with the clinical features of advanced ovarian carcinoma: complex pelvic mass, gross ascites, bilateral pleural effusion and markedly elevated serum CA 125 levels. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Ascites and pleural effusion were not evident and the CA 125 levels returned to normal following surgical excision. A systematic review of reported cases of coexistent benign struma ovarii, pseudo-Meigs’ syndrome and elevated serum CA 125 was performed. Struma ovarii accompanied by pseudo-Meigs’ syndrome and elevated serum CA 125 should be considered in the differential diagnosis of ovarian epithelial cancer. PMID:25789033

    Hybridomas secreting monoclonal antibodies against the K99 antigen of Escherichia coli were produced by the fusion of spleen cells from immunized BALB/c mice with P3/X63-Ag8.653 myeloma cells. The seven hybridomas which produced the highest antibody titers in vitro, as detected by enzyme-linked immunosorbent assay (ELISA) and Perma slide agglutination test (PSAT), were chosen for antibody production in vivo. No cross reaction was observed with K88ab, F41 and P987 antigens in the ELISA. The titer of each ascitic fluid was established by the ELISA and the slide agglutination (SAT) tests. The two ascitic fluids with the highest titer in the SAT were incorporated into the set of antisera used for serotyping at our laboratory. The results were satisfactory both in terms of stability and specificity.

    Background Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of primary effusion lymphomas (PEL). PEL cell lines infected with KSHV, but negative for Epstein-Barr virus have a tumorigenic potential in non-obese diabetic/severe combined immunodeficient mice and result in efficient engraftment and formation of malignant ascites with notable abdominal distension, consistent with the clinical manifestations of PEL in humans. Methodology/Principal Findings Using this preclinical mouse model, we demonstrate that the combination of arsenic trioxide and interferon-alpha (IFN) inhibits proliferation, induces apoptosis and downregulates the latent viral transcripts LANA-1, v-FLIP and v-Cyc in PEL cells derived from malignant ascites. Furthermore, this combination decreases the peritoneal volume and synergistically increases survival of PEL mice. Conclusion/Significance These results provide a promising rationale for the therapeutic use of arsenic/IFN in PEL patients. PMID:24250827

    BACKGROUND Struma ovarii is a rare ovarian teratoma with non-specific clinical presentation that can mimic malignancy, especially when combined with the presence of ascites. Since the surgical procedures performed for benign and malignant tumors are quite different, pre-operative differential diagnosis is key. In this case report we compare the levels of biomarkers CA 125 and HE4 in the differential diagnosis of a suspicious ovarian tumor. CASE REPORT A 75-year-old woman with a palpable mass at the left adnexa, ascites, and high levels of CA 125, underwent a subtotal abdominal hysterectomy and bilateral salpingo-oophorectomy. Histology reported benign struma ovarii. CONCLUSIONS Even though transvaginal ultrasound and CA 125 levels suggested malignancy, HE4 measurements correctly diagnosed benignity. PMID:27381498

    A 5-month-old boy who was diagnosed as having hydrops fetalis at 25 weeks' gestation had severe ascites of unknown origin. At the age 12 months, ultrasonography and computed tomography showed multiple cysts in the spleen that were increasing in size rapidly. Splenectomy resulted in complete disappearance of the ascites. These cysts were diagnosed as mesothelial cysts because the cell lining of the splenic cysts stained positively with alcian blue and cytokeratin. The boy's mother had undergone splenectomy for splenic and retroperitoneal lymphangiomas at 4 years of age. Histological reevaluation showed that the lining of her splenic cysts had the same mesothelial components as her son's. Their chromosomal assay showed normal karyotypes. Mesothelial cyst of the spleen appears similar to splenic lymphangioma morphologically; however, bleomycin and OK-432 were not effective. Familial splenic mesothelial (epidermoid) cysts have been reported in three sets of siblings, but this is the first report of their occurrence in mother and son.

    A case of complete transection of the common bile duct due to abdominal blunt injury in a 49-year-old man is presented. The rarity of this injury and its initial presentation as a pancreatic pseudocyst warrant its description. This patient was diagnosed as having bile duct injury following ascites aspiration. Common bile duct transection was documented and a choledochostomy was done. However, bile leaked into the peritoneal cavity one week after the operation. A Roux-en-Y choledochojejunostomy was done successfully in a second operation. Delayed diagnosis is common in these kinds of injuries, but it should be considered when a patient has bile ascites, abdominal distention and jaundice after a blunt abdominal injury. A review of the literature, methods of diagnosis and the technique of surgical repair are described.

    The authors report two cases of peritoneal tuberculosis observed in Belgium: a 28-year-old black man, immigrant from Ghana and a 24-year-old caucasian woman. In both patients, tuberculosis was associated with another infection. The first patient had a retroperitoneal amoebic cyst and in the second patient Chlamydia trachomatis was found with Koch bacillus in the ascitic fluid. Both patients were successfully treated with appropriate antibiotics. Following the review of recent literature, it appears that the incidence of extrapulmonary tuberculosis is increasing in the industrialized part of the world, peritoneal tuberculosis now representing 0.5% of all cases of tuberculosis. Mortality approaches 7%. The diagnosis is difficult and should be evoked more often in order to be confirmed by appropriate means, such as ascitic fluid adenosine desaminase, bacteriology and peritoneoscopy.

    The effect of 1'-acetoxychavicol acetate (ACA), an anticarcinogenic compound naturally obtained from rhizomes and seeds of South East Asia plants, on the intracellular concentration of glutathione and the activities of enzymes related to glutathione metabolism was studied in Ehrlich ascites tumor cells. We showed in a previous study that ACA induced apoptosis in tumor cells and the cell death was reversed by the addition of N-acetlycysteine or glutathione ethylester. Here we found that ACA caused a rapid decrease in glutathione level in less than 10 min after ACA exposure. At the time, glutathione reductase activity was significantly inhibited and gamma-glutamyl cysteine increased by ACA exposure. These results show that ACA caused the decrease in the intracellular GSH levels in Ehrlich ascites tumor cells, suggesting that ACA-induced decrease of the cellular GSH levels can lead to growth arrest of cancer and enhancement of the efficacy other anticancer drugs.

    2-(4-Amino-3-methylphenyl)-5-fluorobenzothiazole (5F203, NSC 703786) lysylamide belongs to a novel mechanistic class of antitumor agents. It elicits activity against ovarian, breast, kidney and colorectal cancer models. In sensitive breast cancer cells, 5F203 activates aryl hydrocarbon receptor (AhR) signaling. Herein, we evaluate the role of AhR in 5F203 activity in two ovarian cancer cell lines: IGROV-1 (sensitive to 5F203), SKOV-3 (resistant to this agent). In addition, cancer cells have been isolated from ascites fluid of ovarian cancer patients; sensitivity to 5F203 and concurrent AhR signal transduction has been examined in ascites-isolated ovarian cancer patients' cells. 5F203 induced enhanced CYP1A1 expression, AhR translocation and ROS formation in IGROV-1 cells and ascites-isolated ovarian cancer cells that were sensitive to 5F203. In IGROV-1 cells 5F203-induced ROS formation was accompanied by JNK, ERK and P38MAPK phosphorylation, DNA damage and cell cycle arrest prior to apoptosis. In contrast, 5F203 failed to induce CYP1A1 expression, AhR translocation or oxidative stress in 5F203-resistant SKOV-3 cells, or in ovarian cancer ascites cells inherently resistant to this agent. We propose that AhR may represent a new molecular target in the treatment of ovarian tumors and 5F203 may exemplify a potential novel treatment. Furthermore, putative biomarkers of sensitivity to this agent have been identified.

    Eight cases of myxedema with interesting features are presented. Hypertension is common in myxedema and usually persists when the myxedema is treated. Two patients are reported in whom the hypertension improved with the treatment of the myxedema. Other cases presented with ascites, psychosis, recurrent coma with marked hyponatremia and hypochloremia, ataxia, muscular hypertrophy and myotonia. In each patient the abnormalities were corrected by administration of thyroid hormone. In most instances the mechanism whereby symptoms are produced is poorly understood. PMID:14308905

    Spontaneous bacterial peritonitis is an acute bacterial infection of ascitic fluid; it has a high incidence in cirrhotic patients and it is associated with high mortality. In such a situation, early diagnosis and treatment is crucial for the survival of the patient. However, bacterial analysis in ascitic fluid is currently based on culture methods, which are time-consuming and laborious. We report here the application of a photonic interferometer biosensor based on a bimodal waveguide (BiMW) for the rapid and label-free detection of bacteria directly in ascitic fluid. The device consists of a straight waveguide in which two modes of the same polarization interfere while interacting with the external medium through their evanescent fields. A bimolecular event occurring on the sensor area of the device (e.g. capturing bacteria) will differently affect each light mode, inducing a variation in the phase of the light exiting at the output of the waveguide. In this work, we demonstrate the quantitative detection of Bacillus cereus in buffer medium and Escherichia coli in undiluted ascitic fluid from cirrhotic patients. In the case of Bacillus cereus detection, the device was able to specifically detect bacteria at relevant concentrations in 12.5min and in the case of Escherichia coli detection, the analysis time was 25min. Extrapolation of the data demonstrated that the detection limits of the biosensor could reach few bacteria per milliliter. Based on the results obtained, we consider that the BiMW biosensor is positioned as a promising new clinical tool for user-friendly, cost-effective and real-time microbiological analysis.

    The portal hypertension is responsible for many of the manifestations of liver cirrhosis. Some of these complications are the direct consequences of portal hypertension, such as gastrointestinal bleeding from ruptured gastroesophageal varices and from portal hypertensive gastropathy and colopathy, ascites and hepatorenal syndrome, and hypersplenism. In other complications, portal hypertension plays a key role, although it is not the only pathophysiological factor in their development. These include spontaneous bacterial peritonitis, hepatic encephalopathy, cirrhotic cardiomyopathy, hepatopulmonary syndrome, and portopulmonary hypertension. PMID:23024865

    An experiment was conducted to evaluate the effects of a periodically low eggshell temperature exposure during incubation and dietary supplementation of arginine on performance, ascites incidence, and cold tolerance acquisition in broilers. A total of 2,400 hatching eggs were randomly assigned to 2 treatment groups (16 replicates of 75 eggs per treatment). The eggs were incubated at a constant eggshell temperature (EST) of 37.8ºC throughout the incubation period (CON) or were periodically exposed to 15°C for one hour on days 11, 13, 15, and 17 of incubation and the EST was measured (periodical low EST; PLE). After hatching, 240 one-day-old male broiler chicks from both treatment groups were reared for 42 d with or without dietary arginine supplementation in a completely randomized design with a 2 × 2 factorial arrangement. In order to induce ascites, all chicks were exposed to a 15°C room temperature from 14 d onwards. Results showed that second grade chicks and yolk sac weight were decreased, and final body weight was increased in the PLE group. Ascites mortality rate was decreased only in the PLE group and dietary arginine supplementation had no apparent effect. In the PLE group, the packed cell volume (PCV) percentage and red blood cell (RBC) count were decreased. In conclusion, the results showed that the PLE treatment during incubation was associated with improved hatchability, chick quality, and productive performance of broilers and decreased ascites incidence during post hatch cold exposure. Dietary arginine supplementation had no beneficial effects in cold exposed broilers. PMID:27287379

    Capsular polysaccharide antigens isolated from Klebsiella pneumoniae sero-type 1 (K1) and sero-type 3 (K3) could induce tumor necrosis factor-alpha in ICR mice. K1 and K3 capsular antigens were found to be non-toxic by brine shrimp bioassay. When injected into Ehrlich ascites tumor-bearing mice, both K1 and K3 capsular antigens exhibited significant suppression in the growth of tumor cells. The significance of these observations is discussed.

    Antibody to lymphocytic choriomeningitis virus was determined by the indirect immunofluorescence test in immune sera of guinea pigs and immune ascitic fluids of rats and mice. Among 135 patients with aseptic meningitis serum antibody was found in 11 patients in titers of 1 : 64 to 1 : 128 and in the cerebro-spinal fluid of these patients in considerably lower titers. By the indirect immunofluorescence test antibody in maximum titers was found early after the appearance of meningeal symptoms.

    Murine monoclonal antibodies (mabs) are produced in either mouse ascites or bioreactors (spinner culture, stirred-tank reactor, airlift reactor, hollow-fiber reactor). Human mabs are produced solely in bioreactors. Encapsulation represents a special technology. Hybridoma cells have to be adapted prior to growth in bioreactors. Of crucial importance is the construction of over-producing cell lines by cell- and gene-technological methods. Manipulated cell lines often produce modified mabs.

    We describe the case of a 50-year-old woman who presented with tachyarrhythmia, mild fever, peripheral oedema, ascites, epistaxis and gastrointestinal haemorrhage. Blood analysis revealed hyperthyroxinaemia. Analysis of thyroid-stimulating antibodies highlighted Graves' disease being the cause of the prevailing thyrotoxic crisis. Remarkable in this case of thyrotoxicosis is a liver affection without elevated transaminases but disturbed serum protein synthesis leading to hypalbuminaemic oedema and haemorrhagic complications. Thyrostatic treatment led to clinical response.

    Background Previous results have shown that in rats with non-ascitic cirrhosis there is an altered transport of sugars and amino acids associated with elongated microvilli. These alterations returned to normal with the administration of Insulin-Like Growth Factor-I (IGF-I). The aims of this study were to explore the evolution of these alterations and analyse the effect of IGF-I in rats with advanced cirrhosis and ascites. Thus, jejunal structure and nutrient transport (D-galactose, L-leucine, L-proline, L-glutamic acid and L-cystine) were studied in rats with ascitic cirrhosis. Methods Advanced cirrhosis was induced by CCl4 inhalation and Phenobarbital administration for 30 weeks. Cirrhotic animals were divided into two groups which received IGF-I or saline during two weeks. Control group was studied in parallel. Jejunal microvilli were studied by electron microscopy. Nutrient transport was assessed in brush border membrane vesicles using 14C or 35S-labelled subtracts in the three experimental groups. Results Intestinal active Na+-dependent transport was significantly reduced in untreated cirrhotic rats. Kinetic studies showed a decreased Vmax and a reduced affinity for sugar and four amino acids transporters (expressed as an increased Kt) in the brush border membrane vesicles from untreated cirrhotic rats as compared with controls. Both parameters were normalised in the IGF-I-treated cirrhotic group. Electron microscopy showed elongation and fusion of microvilli with degenerative membrane lesions and/or notable atrophy. Conclusions The initial microvilli elongation reported in non ascitic cirrhosis develops into atrophy in rats with advanced cirrhosis and nutrient transports (monosaccharides and amino acids) are progressively reduced. Both morphological and functional alterations improved significantly with low doses of IGF-I. PMID:15196310

    Twelve patients with the Budd-Chiari syndrome have been managed surgically. Ten of the patients were female, two were male, with a mean age of 40 years. Three of the patients had polycythemia vera, two had pre-existing cirrhosis, one had ingested estrogens, one had an occult tumor, and in four there were no associated factors. Ten patients presented with ascites and two with bleeding esophageal varices. The diagnosis was confirmed in all 12 patients by liver biopsy and hepatic vein catheterization. Inferior vena cavography revealed the abdominal vena cava to be thrombosed in six patients. The superior mesenteric vein was used to decompress the congested liver in all 12 patients. In five patients, a mesocaval shunt (MCS) was performed and in seven patients, a mesoatrial shunt (MAS) was carried out. There were four hospital deaths (two MCS, two MAS). One late death (MAS) occurred from liver failure following shunt thrombosis. Two additional patients (one MCS, one MAS) re-developed ascites immediately following surgery and angiography revealed a thrombosed shunt. Ascites has been controlled with a LeVeen shunt in these two patients, but liver biopsies showed progression to cirrhosis. The remaining five patients (three MAS, two MCS) did well, and angiography revealed patent shunts. Two of these patients, however, re-developed ascites at 4 and 10 months following MAS and required a second MAS. Follow-up ranges from 6 to 68 months. In three of the patients (two MCS, one MAS) with patent shunts, liver biopsy shows a remarkable return toward normal liver architecture and histology. Images Fig. 1. Fig. 2. Fig. 3. Fig. 4. Fig. 5.
