The purpose is to provide a uniform, internationally acceptable system by which the histological structure of lymph nodes can be correlated with other parameters of immunological status. The proposed protocols are intended to provide information that is not available in conventional written reports, that use such terms as “hyperplasia” or “nonspecific lymphadenitis”.

    Tuberculosis has staged a global comeback and forms a dangerous combination with AIDS. The abdomen is one of the common sites of extrapulmonary involvement. Patients with abdominal tuberculosis have a wide range and spectrum of symptoms and signs; the disease is therefore a great mimic. Diagnosis, mainly radiological and supported by endoscopy, is difficult to make and laparotomy is required in a large number of patient. Management involves judicious combination of antitubercular therapy and surgery which may be required to treat complications such as intestinal obstruction and perforation. The disease, though potentially curable, carries a significant morbidity and mortality.

    Splenoportagraphy has become an almost indispensable adjunct to the surgical management of portal hypertension. In many instances it will provide the basis for the selection of the operative procedure. Certain instances of intrahepatic portal hypertension due to cirrhosis that might better be managed by splenorenal shunt rather than by the generally preferred method of direct end-to-side portacaval shunt may be determined by this procedure. The procedure finds its greatest application in the accurate delineation of the three major types of extrahepatic portal hypertension, each of which demands a different surgical approach.

    The progressive transformation of illite crystals in alveolar macrophages has been studied with x-ray microanalysis and electron microdiffraction. Illite particles captured by macrophages undergo a series of progressive modifications which affect their ultrastructure, crystalline state, and chemical composition. Crystalline structure progressively disappears and certain elements are eliminated. At the end of the experiment, which lasted more than 6 months, the initial characteristics of the particles were greatly transformed. The constitutive elements of the illite particles were also found in structures other than macrophages: Type I pneumocytes, interstitium, and blood platelets.

    A microscopic, ultrastructural, and morphometric study was made of the gills of tench (Tinca tinca, L.) subjected to acute experimental lead nitrate poisoning. Twenty-one adult tench were subjected to poisoning and a further 22 were used as controls. Lesions were characterized by the appearance of edema and epithelial hyperplasia and necrosis, both in cells forming part of the filtration barrier and in those in the interlamellar space. These processes developed in the course of the experiment, leading to the death of tench after 12 to 15 days of exposure to 75 ppm lead nitrate, at which point the concentrations of lead in the gills had reached their maximum.

    Electron microscopic analysis can be used to determine the three-dimensional structures of macromolecules at resolutions ranging between 3 and 30 A. It differs from nuclear magnetic resonance spectroscopy or x-ray crystallography in that it allows an object's Coulomb potential functions to be determined directly from images and can be used to study relatively complex macromolecular assemblies in a crystalline or noncrystalline state. Electron imaging already has provided valuable structural information about various biological systems, including membrane proteins, protein-nucleic acid complexes, contractile and motile protein assemblies, viruses, and transport complexes for ions or macromolecules.

    Primary correction of congenital clefts of the lip and palate should be designed to carry the interrupted embryonic process to normal completion. This is best accomplished by maxillary alignment with presurgical orthodontics, stabilisation of the maxillary alignment, obliteration of the alveolar cleft and construction of the nasal floor with periosteoplasty. This allows early construction of the lip by rotation and advancement and correction of the nose with columella lengthening, alar cartilage positioning and alar base cinching. This can be accomplished before school age.

    During the final stages of their evolution, stars with low to intermediate masses produce huge quantities - up to the order of earth masses per year - of dust grains. This production of solid particles is of crucial importance both for the physico-chemical conditions in the respective circumstellar environments and for the cosmic cycle of matter. The branch of astronomy dealing with cosmic dust - sometimes referred to as solid state astrophysics - uses three principal methods: astronomical infrared spectroscopy, laboratory measurements of optical properties of solids and modelling the chemical and physical processes going on in the atmospheres of evolved stars. Considerable progress has been achieved, during the past decade, in solid state astropyhsics; specific questions have arisen which necessitate new, dedicated measurements and observations. Here we highlight some aspects of this progress and then proceed to outlining insights in this field which are about to be attained by means of new satellite facilities such as Spitzer and Herschel.

    This article describes six patients who presented, usually bilaterally, with yellow-orange, elevated, indurated, and nonulcerated xanthomatous eyelid lesions, typically extending into the anterior orbital fat, and sometimes involving the extraocular muscles and the lacrimal gland. Because the eyelids remained intact and because the process did not reach the deep orbital and perioptic connective tissues, visual acuity was well preserved. There is cosmetic morbidity and occasionally motility restriction with advancing involvement of the extraocular muscles. All patients had variably severe adult-onset asthma that required treatment with systemic prednisone and inhalants. No evidence of Erdheim-Chester disease was found in any patient, but the appearance in one patient, after 25 years of follow-up, of a separate subcutaneous necrobiotic xanthogranulomatous lesion in the mandibular region with an associated paraproteinemia, suggests that at least some of our cases might be a mild form of necrobiotic xanthogranuloma. For this reason, we would suggest repeated periodic serum protein immunoelectrophoretic studies as well as evaluation for lymphoma. Therapy probably should consist of low doses of periorbital radiotherapy coupled with high doses of corticosteroids. Should this not be successful, then systemic administration of corticosteroids with chemotherapeutic agents might be efficacious, as in necrobiotic xanthogranuloma.

    The capability to extract objective and quantitatively accurate information from 3-D radiographic biomedical images has not kept pace with the capabilities to produce the images themselves. This is rather an ironic paradox, since on the one hand the new 3-D and 4-D imaging capabilities promise significant potential for providing greater specificity and sensitivity (i.e., precise objective discrimination and accurate quantitative measurement of body tissue characteristics and function) in clinical diagnostic and basic investigative imaging procedures than ever possible before, but on the other hand, the momentous advances in computer and associated electronic imaging technology which have made these 3-D imaging capabilities possible have not been concomitantly developed for full exploitation of these capabilities. Therefore, we have developed a powerful new microcomputer-based system which permits detailed investigations and evaluation of 3-D and 4-D (dynamic 3-D) biomedical images. The system comprises a special workstation to which all the information in a large 3-D image data base is accessible for rapid display, manipulation, and measurement. The system provides important capabilities for simultaneously representing and analyzing both structural and functional data and their relationships in various organs of the body. This paper provides a detailed description of this system, as well as some of the rationale, background, theoretical concepts, and practical considerations related to system implementation.

    The acquired immune deficiency syndrome (AIDS) is a devastating new illness which appears to be sexually and parenterally transmissible. AIDS was first described in the male homosexual community; however, the disease has more recently been described among intravenous drug abusers, Haitians, hemophiliacs, and others. The etiologic agent is unknown. AIDS may represent an infection by a previously undescribed organism, a mutant of a known microorganism, or a multifactorial combination of environmental, immunologic, and genetic factors. As a consequence of the disease's seemingly irreversible ablation of the cell-mediated immune system, AIDS victims succumb to a variety of infections and/or unusual neoplasms. In its fully developed form, mortality approaches 100%. At autopsy the gross and microscopic pathology of the syndrome can be divided into three general categories: 1) morphologic manifestations of profound lymphoid depletion; 2) infections, usually with mixed opportunistic pathogens; and 3) unusual neoplasms, most frequently Kaposi's sarcoma or high-grade lymphomas.

    Objective: To discuss the rehabilitation program after anterior cruciate ligament (ACL) reconstruction in the female athlete. In addition, we will discuss 8 unique characteristics identified in the female athlete and specific training drills to address and correct the potentially deleterious effects of these unique characteristics. Background: The female athlete appears to be more susceptible to noncontact ACL injuries than the male athlete. There seem to be many differences between the female and male athlete that may contribute to the increased injury rate in the female athlete. These variations include anatomical and neuromuscular considerations and differences. Description: Based on the unique characteristics of the female athlete and the anatomical and neuromuscular dissimilarities, a specially designed rehabilitation program has been established for the female athlete after ACL surgery. Clinical Advantages: The rehabilitation drills discussed in this article challenge the neuromuscular system through proprioception, kinesthesia, dynamic joint stability, neuromuscular control, and perturbation training activities. Improving the female athlete's neuromuscular system will, we believe, expedite the injured athlete's recovery after ACL injury or surgery. Although the concepts discussed are part of a postoperative rehabilitation program after ACL surgery, these concepts may also be implemented as a preventive program to assist in reducing the incidence of ACL injuries in the female athlete.

    This paper presents an ultrastructural study of the changes occurring in the gastrocnemius tendon of normal and selenium-deficient ducklings from 1 to 12 days of age. The study revealed that the normal 1--8-day-old duckling tendon contained 2 morphologically distinct cell types and a third occurring at Days 8--12. The location of these cells within the endotendineum and fiber bundles and their morphologic characteristics are presented. Most cells showed cytologic alterations as early as 4 days on the deficient diet with progressive deterioration to Day 12. The various cell types showed a differential response to the deficiency. Changes included altered endoplasmic reticulum and Golgi apparatus and eventual cell rupture. The significance of these observations and their possible relationship to the etiology of selenium-deficiency-induced dystrophy is discussed.

    Familial canine dermatomyositis is a recently identified disease of collie dogs that resembles human juvenile dermatomyositis. The lesions in the skin and muscles obtained by biopsy from two litters of dogs were characterized for the purpose of determining the similarity of the lesions to those of human dermatomyositis. The cutaneous lesions began between 7 and 11 weeks of age and were present on the face, lips, ears, and skin over bony prominences of the limbs, feet, sternum, and tip of the tail. Histologically the cutaneous lesions frequently consisted of vesicles, pustules, and ulcers on the lips, face, and ears. Neutrophils, lymphocytes, mast cells, and macrophages were present throughout the dermis. Neutrophils and lymphocytes were also present in and around vessels. Between 13 and 19 weeks of age generalized muscle atrophy was noted. The muscle lesions consisted of interstitial lymphocyte, plasma cell, macrophage, and neutrophil accumulation; myofiber degeneration, regeneration, and atrophy; and fibrosis. Perivascular neutrophils, lymphocytes, and plasma cells were also seen. Histologically, the lesions resembled those present in human juvenile dermatomyositis; and these observations, coupled with clinical, immunologic, and clinical pathologic observations presented elsewhere, suggest that familial canine dermatomyositis is an appropriate and potentially useful model for human juvenile dermatomyositis.

    This paper provides a cursory overview of attempts to discover, preserve and disseminate the history of the chiropractic profession, up to and including the organization of the Association for the History of Chiropractic (AHC). A surprisingly wide range of materials have been available for many decades, but sustained efforts at historical scholarship are more recent (past quarter century). The quality of these works has been uneven, but has improved with the emergence of chiropractic scholarly periodicals and interest from non-chiropractor investigators. Affiliates of the American-based AHC are located in Australia and Canada; organized historical scholarship in other regions of the world has yet to develop. Several substantial archival resources for historical investigations are available, and merit greater scrutiny and support within the profession.

    The experimental studies performed on nonpigmented rat choroids and the review of the important literature covered in this thesis seem to justify the following statements: 1. Mast cells are present in the choroid in significant numbers. 2. Mast cell numbers vary considerably from one individual to another and from one location in the choroid to another. 3. The major concentration of mast cells in the uvea is in the posterior choroid. 4. The mast cells of the choroid have a preferential location along arterial vessels. 5. Choroidal mast cell population density apparently decreases with senescence. 6. Mast cell products are present in sufficient quantity to exert substantial effects on physiologic, immunologic, and inflammatory responses in the choroid. 7. Choroidal mast cell products are released with appropriate stimulation and share some properties with the connective-tissue mast cell. 8. Choroidal mast cell demonstrate enough differences to suggest that a local differentiation may be present and may represent a locally controlled modulating effect for choroidal physiologic, immunologic, and inflammatory reactions.

    To study the morphologic and biochemical changes occuring in liver mitochondria during recovery from ethanol-induced injury, rats fed a 6-month high-alcohol regimen plus a nutritionally adequate diet which did not induce fatty liver were compared with isocalorically fed controls. After this period the alcohol-fed animals displayed striking ultrastructural changes of liver mitochondria and a decreased respiratory activity with succinate or malate-glutamate as substrate. On the contrary, the respiratory rate with I-glycerophosphate was 50% increased. Regression changes were studied after alcohol was withdrawn from the diet. Enlarged mitochondria rapidly disappeared (in 24 hours), although a few megamitochondria were still present after 8 days of abstinence. A similar recovery was observed for the functional alterations. At the end of the experimental period, only a slight decrease of the maximal respiratory rate using malate-glutamate as a substrate was noted. The ultrastructural findings and the morphometric data suggest that the way in which mitochondrial normalization takes place is based on partition of these organelles.

    Studies were done on the structural changes that develop in Ionescu-Shiley valves that are used as replacement heart valves for 4 to 8 years. These changes were compared with those found in similarly used porcine aortic valve (PAV) bioprostheses. A variety of morphologic differences were observed between bovine pericardial valve (BPV) and PAV bioprostheses after orthotopic implantation including: primary tissue failure associated with the use of an alignment suture, thickening of valve leaflet, leaflet tissue delamination, leaflet calcification, and dystrophic alterations of collagen. These findings indicate that valve design criteria directly influence the durability of pericardial valves. However, other factors unique to pericardial tissue also affect the durability and performance of BPVs. These factors include the inability of pericardial tissue to accommodate dynamic stresses; the extensive insudation of plasma proteins and lipids; and the inability to reduce leaflet calcification using agents that effectively mitigate calcification in PAV bioprostheses.

    Rats, hamsters, and guinea pigs were exposed by inhalation to different concentrations of potassium octatitanate fibers. Following 3 months of exposure, the animals were sacrificed between the 15th and 24th month. The exposed animals showed dose-related dust deposition and pulmonary fibrosis mainly in the respiratory bronchiolar region. Most short fibers (less than 5 micrograms) were phagocytized by alveolar macrophages, but long fibers (greater than 10 micrograms) were phagocytized by foreign body giant cells. Dust-laden macrophages (dust cells) entered into the lumen of bronchial lymphatic or pulmonary blood vessels. Numerous dust cells were transported from the lung to the tracheobronchial and mediastinal lymph nodes where some dust cells penetrated into the blood or lymphatic circulation. Massive direct cell migration of the mediastinal adipose tissue from the lymph nodes occurred occasionally. Dust-laden giant cells were found only occasionally in the liver, and there was widespread migration of the fibers into other vital organs and tissues without any significant responses.

    Eighteen cases of medullary carcinoma of the thyroid were analyzed immunohistochemically for calcitonin- and ACTH-containing cells, and tumor cells in 8 cases were examined by an electron microscope and analyzed by manual and computer procedures with particular attention paid to the size and quality of secretory granules. Calcitonin- and ACTH-containing cells were found singly or in clusters in 14 and 11 tumors, respectively. In 4 cases, calcitonin-positive cell clusters and an increase in number of singly scattered C cells were seen apart from the main tumor, suggesting a multicentric nature of certain medullary carcinomas. Some ACTH-containing cells were apparently also positive for calcitonin. In a case of familial Sipple disease, follicular lining cells were replaced in areas with ACTH-containing cells. Three to five frequency distribution curves of the size of secretory granules were obtained in all of 6 cases analyzed, and at least two different types of granule matrix were identified.

    PURPOSE: This paper describes the surgical rehabilitation of a child with craniofacial anomalies, unilateral syndactyly, and partial unilateral cryptophthalmos associated with inferior colobomata of the iris and optic nerve and agenesis of the inferior rectus and inferior oblique muscles. The clinical presentation of cryptophthalmos is described. METHODS: The medical literature since the original description of cryptophthalmos in 1872 was reviewed to define patterns of inheritance and the incidence of associated anomalies. RESULTS: Including this patient, 149 case reports of cryptophthalmos were identified. In two families transmission from parent to child suggests dominant inheritance. None of the five dominant cases had any other anomalies, and all had bilateral complete cryptophthalmos. The incidence of cryptophthalmos in the remaining families is consistent with autosomal recessive inheritance. This group includes patients with bilateral, unilateral, and partial cryptophthalmos. Other anomalies are common, including those of the ear and nose, limbs, genitourinary system, and mouth and palate. Mortality in the perinatal period is associated with renal agenesis, laryngeal atresia, and pulmonary hypoplasia. CONCLUSIONS: Cryptophthalmos is a rare congenital anomaly with two patterns of inheritance.

    The sequence of cellular and biochemical events in response to the deposition of dust particles in lung tissue is described. Primary reactions at the lung surface include changes in the free cell population, the alveolar surface protein and in the quantity of pulmonary surfactant, a lipoprotein-rich material secreted by Type II cells. The relationship between these changes and lung fibrogenesis is discussed. It is suggested that such primary changes are protective mechanisms which may assist in the prevention of fibrogenesis rather than lead to an increase in collagen formation and deposition. If these primary defenses are overcome, then the interstitial fibroblastlike cell may have a prominent role in fibrogenesis. Therefore detailed observations of the interaction between lung fibroblasts and mineral dusts in vitro are described. As fibrogenesis may be arrested in vivo, or possibly reversed, and does not always progress to fibrosis, final consideration is given to the step from fibrogenesis to fibrosis. It is suggested that this step may involve other tissue proteins apart from collagen and that the irreversible nature of fibrosis can be explained by the formation of strong intermolecular crosslinks between different proteins. The types of crosslinks that may be involved are discussed. Emphasis is placed on the role of calcium-dependent transglutaminases in fibrosis, as these enzymes have hitherto received little attention. Images FIGURE 3. FIGURE 4. FIGURE 5. FIGURE 6. FIGURE 7.

    Specimen arteriography, morphometry, and light and electron microscopy were used for examination of the pulmonary vasculature of 22 patients who died with the adult respiratory distress syndrome (ARDS), for the purpose of defining the lesions that contribute to pulmonary hypertension in this setting. The different lesions correlated with the duration rather than the cause of ARDS. Thromboemboli occurred in 21 patients, and macrothrombi found at autopsy correlated with the number of filling defects on antemortem angiography. Acute endothelial injury was documented ultrastructurally even in intermediate and late-stage patients. Fibrocellular intimal obliteration of arteries, veins, and lymphatics and infective vasculitis were prominent in those surviving beyond 10 days. In long-term survivors, tortuous arteries and irregularly dilated capillaries were striking features. Peripheral extension of vascular smooth muscle and a significant increase in the percentage of medial thickness of muscular arteries with duration of ARDS were noted. The pathogenesis and clinical significance of these lesions is discussed. Images Figure 1 Figure 2 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 Figure 12 Figure 13 PMID:6859225

    N,N-dimethylacetamide, hexamethylene bisacetamide, and Polybrene induced rapid and extensive differentiation in vitro in an otherwise slowly differentiating subline of embryonal carcinoma cells. The type of differentiated cell induced was dependent on the spatial organization of the stem cells during drug treatment. In monalayer culture "epithelial" cells were produced exclusively. However, treatment of aggregated suspension cultures yielded predominantly "fibroblast-like" cells. The undifferentiated embryonal carcinoma cells and the two differentiated cell types were morphologically distinct when examined by light microscopy, scanning electron microscopy, and transmission electron microscopy; and they had differences in cell surface antigens. Both differential cell types produced large amounts of fibronectin, whereas the embryonal carcinoma cells produced only minimal amounts. This system provides a convenient way to induce relatively synchronous differentiation of embryonal carcinoma cells into specific differentiated cell types.

    The initial stages in the rehabilitation of a male child with severe microblepharon, corneal opacities, bilateral facial clefts, bilateral complete cleft lip and palate, and unilateral syndactyly are described. Review of the literature suggests that severe microblepharon is associated with other craniofacial anomalies, and often the child is stillborn or retarded. Surviving children have been abandoned because of their appearance. The child described in this case appears to be unique because his intelligence is normal, and, to our knowledge, this is the first reported case of penetrating keratoplasty after reconstruction of functional eyelids. The principal problems after corneal grafting appear to have been chronic partial exposure due to inadequate lid length and a poor Bell's reflex and the persistence of a rim of vascularized fibrous tissue around the corneal graft. Future reconstructive surgery is outlined.

    The mineral pneumoconioses (lung disease caused by inhalation of inorganic dust) have been an important disease entity for centuries. In the last several decades, the electron microscope has been used to elucidate the distribution and identification of inhaled minerals, to aid in establishing etiologic factors, and less commonly, to determine the basic biologic mechanisms through which inhaled minerals cause lung disease. In this section, I review the instrumentation and tissue preparation currently used to address some modern problems in particle-induced lung disease. For example, human pneumoconioses of undetermined etiology can be clarified by electron microscopy and X-ray energy spectrometry. In addition, the initial deposition patterns of asbestos and silica are demonstrated in animal models, and the contributions of electron microscopy in establishing the initial lesions of asbestosis are described.

    A histochemical study was performed on light- and electron-microscopic level in a case of Fabry's disease. The patient underwent kidney transplantation for renal failure and died of heart failure 6 months later. Patient's tissues were studied at the light- and electron-microscopic levels with various embedding and staining techniques for lipids and carbohydrates. Two peroxidase-labeled lectins (from Ricinus communis and from Bandeiraea simplicifolia) known to have affinity for alpha- and beta-D-galactose, were strongly reactive with the storage material on frozen sections. The ultrahistochemical and extraction tests showed that the typical granules had a variable reactivity and morphologic characteristics in different cells, probably reflecting different composition. A small number of typical deposits were also observed in the transplanted kidney. This is the first reported case of recurrence of the storage disease in the allograft. Of interest was also the fact that the patient's blood inhibited normal alpha-galactosidase activity, suggesting a possible inhibitor-related mechanism in the pathogenesis of the recurrence.

    Lung inflammation was induced in rabbits by intratracheal injections of chemotactic fragments obtained from zymosan-activated serum (CF-ZAS), and the route of vascular emigration and alveolar surface interaction of polymorphonuclear leukocytes (PMNs) and monocytes migrating into the lung was characterized by transmission (TEM) and scanning (SEM) electron-microscopic examination. Leukocytes migrated from capillaries and venules into the alveolar wall interstitium by adherence to the vascular endothelium and migration through the endothelial intracellular junction to attain a position between a reapposed endothelial cell junction and the vascular basement membrane. The cells then migrated into the interstitium through a narrow opening in the basement membrane. Leukocyte entrance into the alveolar space from the interstitium appeared to occur through small openings in the epithelial basement membrane at or near the Type I epithelial intercellular junction. Once in the alveolus, PMNs and macrophages demonstrated surface adherence and spreading along with evidence of migration, pseudopod extension, interalveolar pore transit, and retraction fiber formation. This study indicates the leukocyte influx into the alveolus in acute chemotactic-factor-induced inflammation is via a continuum of migrational activity, beginning at the pulmonary capillary endothelial surface and persisting on the alveolar epithelial surface.

    Ultrastructural lesions of the liver were studied in 12 patients with peliosis hepatis. This vascular lesion consisted of cavities filled with red blood cells and sometimes lined with an endothelial barrier; the cavities were due to cystic dilatation of the space of Disse and/or sinusoidal lumen. The passage of red blood cells through the endothelial barrier was occasionally demonstrated. Other striking alterations included the presence of numerous blebs on the sinusoidal membrane of the hepatocytes and the existence of multiple cellular layers lining the sinusoids. Perisinusoidal fibrosis appeared on follow-up biopsies in 3 patients. There was no major abnormality of the hepatocytes or of the hepatic venules. These findings suggest that alterations of the sinusoidal barrier might constitute the primary event in peliosis, although secondary changes to increased pressure and hypoxia within the lobules cannot be excluded.

    The gray platelet syndrome (GPS) is a rare inherited disorder in which peripheral blood platelets are relatively large, vacuolated, and almost devoid of cytoplasmic granulation. In the present study we have evaluated the ultrastructure and cytochemistry of platelets from 2 patients with the GPS to determine precisely which organelles are missing from their cells. The findings indicate that gray platelets contain normal numbers of mitochondria, dense bodies, peroxisomes, and lysosomes but specifically lack alpha-granules. Preliminary studies of megakaryocytes from 1 of the 2 patients suggest that the defect in granule formation may lie at the level of the Golgi zone.

    The pathogenesis of experimentally induced cecal amebiasis in gerbils (Meriones unguiculatus) was studied from 5 to 60 days after inoculation. Ulcerative lesions were noted 10 to 60 days after inoculation. The sequential development of lesions was asynchronous and progressed from destruction of the interglandular epithelium and of glandular crypt elements to loss of mucosa and formation of granulomatous lesions in the submucosa involving the muscularis mucosae. Pathologic changes in the liver correlated with the formation of ulcerative cecal lesions. Subacute hepatic changes showed lymphocytic portal infiltrate, Kupffer cell hyperplasia, multinucleated giant cells, granuloma formation, and sinusoidal mononuclear and granulocytic infiltrates. Metastatic amebic liver abscesses occurred as early as 10 days after inoculation, and small abscesses were found in the portal areas of the right liver lobe.

    Sequential development and pathology of experimentally induced amebic liver abscess in the gerbil (Meriones unguiculatus) were studied from 1 to 60 days after inoculation. Early lesions were characterized by an acute inflammatory response, which became granulomatous at 5 days. Early granulomas were discrete, with well-defined fibrohistiocytic walls. Trophozoite dissemination as a result of fibrolysis of granuloma wall was confined to the liver parenchyma. The granulomatous cellular infiltrate (less than 20 days) was characterized by granulocytes and histiocytes; older granulomas (greater than 30 days) were composed of lymphocytic infiltrate, plasma cells, and a few granulocytes, and were characterized by the absence of epithelioid histiocytes. The degree of pathologic change adjacent to liver granulomas followed the sequential development of the amebic liver abscess. Severe changes observed were portal canal lymphocytic infiltration, the presence of foreign body giant cells, periportal fibrosis, proliferation of bile duct epithelium, and hepatocyte anisonucleosis and ballooning degeneration.

    The clinical course of SPA of the orbit is associated with the age of the patient. That association might be explained through a series of intermediate relationships: the clinical course correlates with the bacterial constituency, the bacterial constituency is related to physiologic derangement within the sinuses, the physiologic derangement may vary with the degree of obstruction of the sinus ostia, and the ostial caliber relative to the volume of the cavity that must be drained decreases with patient age into late adolescence. The controversy between pediatricians and surgeons over the appropriate indications for drainage might be resolved with the acknowledgement that each side is correct on the basis of the patient populations treated. It is hoped that recognition of the age-related variations in SPA will permit a more systematic approach to the management of this complex infectious disease.

    Association of group A streptococci with acute rheumatic fever and valvular heart disease is well established; however the basis of valve injury remains unclear. In this study, anti-streptococcal monoclonal antibodies (MAbs) cross-reactive with myocardium were reacted with sections from 22 rheumatic valves, nine normal, five endocarditic, one 'floppy,' and one Marfan valve. In immunohistochemical studies, MAb reactivity was observed with cardiac myocytes, smooth muscle cells, cell surface and cytoplasm of endothelial cells lining valves, and valvular interstitial cells. Endothelial basement membrane and elastin fibrils reacted with the MAbs, whereas collagen was unreactive. Similar reactivity was seen with sera from acute rheumatic fever patients. The anti-streptococcal MAbs reacted with intravalvular myosin and vimentin in Western blots, and purified elastin competitively inhibited the binding of the anti-streptococcal MAbs to whole group A streptococci. The data show that human heart valves have numerous sites of immunoreactivity with anti-streptococcal MAbs and acute rheumatic fever sera of potential importance in the pathogenesis of rheumatic valvular injury.

    This clinicopathologic study of patients with chronic graft-versus-host disease (GVHD) after allogeneic marrow transplantation emphasizes the most prominent feature of the syndrome, the cutaneous aspects, and describes the ophthalmic-oral sicca syndrome with sialoadenitis and the neurologic findings. Chronic cutaneous GVHD affected 19 of 92 recipients surviving 150 days or more. In 6 patients chronic GVHD presented as a continuation of acute GVHD; in 8 it occurred after the resolution of acute GVHD; and in 5 it arose without preceding acute GVHD, ie, de novo late onset. Two cutaneous types were distinguished. The generalized type affected 16 patients and ran a progressive course resulting in late complications of poikiloderma, diffuse dermal and subcutaneous fibrosis, and contractures. Microscopically, it resembled generalized morphea and lupus erythermatosus hypertrophicus et profundus. The local type affected 3 patients with a more variable picture of poikiloderma, dermal sclerosis, and contractures. Microscopically, it resembled lupus of erythematosus profundus and scleroderma.

    Recombinant human interleukin-1 beta (rhuIL-1 beta) was investigated in a randomized, blinded placebo-controlled trial to evaluate its effect on the healing of chronic pressure ulcers. The influence of this topically applied cytokine to 26 pressure ulcer patients was correlated with tissue culture and electron microscopic evaluation. Cellular replication studies showed that low (0.01 micrograms/cm2/day) and medium (0.1 micrograms/cm2/day) concentrations of rhuIL-1 beta were not effective in extending replication in pressure ulcer fibroblasts, in vitro. Tissue culture measurements from pressure ulcer biopsies demonstrated that, after 29 days of a high level of rhuIL-1 beta treatment (1.0 micrograms/cm2/day), the cytokine was effective in extending the ability of pressure ulcer fibroblasts to replicate. Tissue culture and electron microscopy suggested that, although rhuIL-1 beta promoted increases in fibroblast numbers, the primary effect appeared to be development of the extracellular matrix. The possible direct and indirect influences of rhuIL-1 beta therapy on pressure ulcers are discussed.

    1992-01-01

    The current study traces the development of contractile cells in the nonmuscular segments of rat lung microvessels in hyperoxic pulmonary hypertension. New intimal cells first develop into a well-defined layer beneath the endothelium and internal to an elastic lamina. Ultrastructurally, these cells are found to be 1) fibroblasts recruited to the vessel wall from the interstitium and 2) intermediate cells, a population of preexisting vascular cells (structurally between a smooth muscle cell and a pericyte). Early in hyperoxia (days 3 through 7), interstitial fibroblasts migrate and align around the smallest vessels in which an elastic lamina is either absent or fragmentary. These cells then are incorporated into the vessel wall by tropoelastin secretion and the formation of an elastic lamina along their abluminal margin. After day 7, the new mural fibroblasts acquire the features of contractile cells, namely a basal lamina, extensive microfilaments, and dense bodies. In other vessels, as early as day 3 of hyperoxia, intermediate cells within the vessel intima begin to acquire the additional filaments and dense bodies of contractile cells. As hyperoxia continues, each cell pathway gives rise to vessels with distinct intimal or medial layers of contractile cells. In this way, thick-walled 'newly muscularized' vessel segments form adjacent to the capillary bed.

On days 1-4, extensive necrosis with contraction bands was present. Rapid macrophagic invasion and phagocytosis of sarcoplasmic debris was seen on days 2 and 4. Missing necrotic myocytes were outlined by persistent "tubes" of external laminas. In some surviving myocytes, sublethal injury was evident on day 1 by mitochondria with condensed conformation and on days 2, 4, and 16 by moderate to marked myofibrillar lysis and sarcoplasmic vacuolation. Monensin cardiotoxicity in pigs constitutes a unique example of selective injury to atrial myocardium.

    By light microscopy the subdermal nodule of a patient with fibrodysplasia ossificans progressiva (FOP) had a fibromatoid histologic appearance. The cytoplasm of the cells stained strongly for mannose-rich glycoprotein with the concanavalin A-horseradish peroxidase (con A-HRP) method. The tumors also exhibited abundant hyaluronidase-digestible mucopolysaccharide in the interstitium with various basic staining reagents. This material appeared to consist principally of hyaluronic acid or chondroitin sulfate with few or mainly masked sulfate esters. At the ultrastructural level, cells interpreted as the tumor cells in the subdermal nodule from the patient displayed extremely hyperplastic granular reticulum and well-developed Golgi elements and appeared very active in synthesis and secretion of protein. The material in the dilated cisternae of the granular reticulum stained for glycoprotein with the con-A-HRP method. Macrophages which comprised the other main cell type in the nodules commonly contacted the tumor cells and occasionally evidenced engulfment of these cells. The intercellular matrix of the nonossified subdermal nodule exhibited greatly increased mucosubstance and, by electron microscopy, showed an unusual network of dialyzed iron-reactive acid muco-substance in the interstitium.

    The authors examined tissues obtained by biopsy, pancreatectomy, and autopsy from 100 pancreas grafts to determine the cause of dysfunction or failure of the graft. Immunohistologic examination of 42 tissues to determine the mononuclear cell phenotypes and Class I and II antigen expression was performed as well. Technical factors--infections, thrombosis, obstruction--accounted for a large number of graft losses, but immunologic-mediated mechanisms resulted in graft dysfunction and failure as well. Pleomorphic inflammatory infiltrates were present in grafts with acute rejection, as well as Silastic and Prolamine duct-obstructed grafts. Criteria useful in the identification of acute rejection from pancreatitis included a more intense, predominantly mononuclear cell infiltration of transformed lymphocytes in the exocrine pancreas and evidence of vascular rejection--endovasculitis or fibrinoid necrosis. Increased expression and/or induction of Class I and II antigens on pancreatic constituents occurred in grafts with evidence of acute rejection, but also with Silastic and prolamine duct-obstructed pancreatitis. An isletitis occurred in 25% of the grafts. Nine of the 25 grafts (36%) with isletitis also had selective loss of beta cells from the islets. Recurrent diabetes mellitus appeared to have developed in these cases, which accounted for loss of graft function.

    Obesity is a chronic disease due to excess fat storage, a genetic predisposition, and strong environmental contributions. This problem is worldwide, and the incidence is increasing daily. There are medical, physical, social, economic, and psychological comorbid conditions associated with obesity. There is no cure for obesity except possibly prevention. Nonsurgical treatment has been inadequate in providing sustained weight loss. Currently, surgery offers the only viable treatment option with longterm weight loss and maintenance for the morbidly obese. Surgeries for weight loss are called bariatric surgeries. There is no one operation that is effective for all patients. Gastric bypass operations are the most common operations currently used. Because there are inherent complications from surgeries, bariatric surgeries should be performed in a multidisciplinary setting. The laparoscopic approach is being used by some surgeons in performing the various operations. The success rate--usually defined as >50% excess weight loss that is maintained for at least five years from bariatric surgery--ranges from 40% in the simple to >70% in the complex operations. The weight loss from surgical treatment results in significant improvements and, in some cases, complete resolution of comorbid conditions associated with obesity. Patients undergoing surgery for obesity need lifelong nutritional supplements and medical monitoring.

    John J. Nugent, D.C. is remembered by many as either the “Abraham Flexner of Chiropractic” or the “anti-Christ of Chiropractic.” From 1941 until his forced retirement in 1959, the Irish-born Palmer graduate was one of the most important factors in the profession's educational reforms. Yet Nugent's work as the National Chiropractic Association's (NCA's) director of research was not the beginning of the campaign to upgrade chiropractic education. This paper looks at earlier influences and events which set the stage for Nugent's campaign. Among these were the introduction of licensure for chiropractors, the self-defeating actions of B.J. Palmer, the introduction of basic science legislation, the lethargy of the schools, and the struggle for control of education between the schools, on the one hand, and the NCA and the Council of State Chiropractic Examining Boards on the other ImagesFigure 1Figure 3Figure 4Figure 5Figure 6Figure 7Figure 9Figure 10Figure 11Figure 12Figure 13Figure 14Figure 15Figure 16Figure 17Figure 18Figure 19Figure 20Figure 21Figure 22Figure 23Figure 24Figure 25Figure 26Figure 28Figure 29Figure 30Figure 31Figure 32Figure 33Figure 34Figure 35Figure 36Figure 37Figure 38

    Chronic adriamycin (ADR) intoxication was produced in three groups of beagle dogs by weekly intravenous injections (1 mg/kg body weight) for 20 weeks (cumulative dose 400 mg/sq m). Group A (6 dogs) received ADR only; Group B (6 dogs) were given ADR and weekly doses of vitamin E (17 mg/kg body weight) as alpha-tocopherol acetate; and Group C (6 dogs) received ADR and weekly doses of vitamin E as did Group B and selenium (0.06 mg/kg body weight as selenite). Each of the 18 dogs developed ADR-induced cardiomyopathy (CMY), and death occurred in 11 dogs during Weeks 17-20. Mortality was lowest in Group B (2 of 6), but no differences between groups were seen either in survival time of the dogs that died or in severity of CMY. Cardiomyopathy was more severe in dogs that died than in survivors. Congestive heart failure with transudation was present in 4 of 11 dogs that died. Cardiac histopathology was characterized by vacuolar degeneration of myocytes. Myocardial damage was most severe in the left ventricle and the ventricular septum, intermediate in the right ventricle and the left atrium, and least in the right atrium. Ultrastructural study showed that an early alteration in damaged myocytes was distention of sarcoplasmic reticulum to form sarcoplasmic vacuoles. Occasional damaged fibers had myofibrillar lysis and focal proliferation of sarcoplasmic reticulum. This study demonstrates that the dog offers a suitable model for studies of chronic ADR cardiotoxicity in man. The lack of cardioprotection from vitamin E and selenium supplementation fails to support the proposed role of lipoperoxidative damage in the development of chronic ADR-induced CMY.

    This review paper examines the relationship between chemicals inducing excessive accumulation of alpha 2u-globulin (alpha 2u-g) (CIGA) in hyaline droplets in male rat kidneys and the subsequent development of nephrotoxicity and renal tubule neoplasia in the male rat. This dose-responsive hyaline droplet accumulation distinguishes CIGA carcinogens from classical renal carcinogens. CIGA carcinogens also do not appear to react with DNA and are generally negative in short-term tests for genotoxicity, CIGA or their metabolites bind specifically, but reversibly, to male rat alpha 2u-g. The resulting complex appears to be more resistant to hydrolytic degradation in the proximal tubule than native, unbound alpha 2u-g. Single cell necrosis of the tubule epithelium, with associated granular cast formation and papillary mineralization, is followed by sustained regenerative tubule cell proliferation, foci of tubule hyperplasia in the convoluted proximal tubules, and renal tubule tumors. Although structurally similar proteins have been detected in other species, including humans, renal lesions characteristic of alpha 2u-g nephropathy have not been observed. Epidemiologic investigation has not specifically examined the CIGA hypothesis for humans. Based on cancer bioassays, hormone manipulation studies, investigations in an alpha 2u-g-deficient strain of rat, and other laboratory data, an increased proliferative response caused by chemically induced cytotoxicity appears to play a role in the development of renal tubule tumors in male rats. Thus, it is reasonable to suggest that the renal effects induced in male rats by chemicals causing alpha 2u-g accumulation are unlikely to occur in humans. Images FIGURE 1. FIGURE 2. FIGURE 3.

    PubMed Central

    Anderson, D R

    1981-01-01

    Tissue from ten eyes with infantile glaucoma and from 40 normal eyes of fetuses and infants without glaucoma were examined by light and electron microscopy. In normal development, the corneoscleral coat grows faster than the uveal tract during the last trimester, leading to a posterior migration of the ciliary body attachment from Schwalbe's line (5th month) to the scleral spur (9th month), and then to a location behind the scleral spur (postnatally). In infantile glaucoma, the insertion of the anterior ciliary body and iris overlaps the trabecular meshwork, similar to the late fetal position. The trabecular sheets are perforated, and there is no membrane over the surface of the trabecular meshwork. The trabecular beams are thicker than in normal infant eyes. There is both histologic and clinical evidence of traction on the iris root exerted by the thickened trabecular beams. These findings suggest that in congenital glaucoma the thickened beams had prevented the normal posterior migration of the ciliary body and iris root. This traction may compact the thickened trabecular beams, obstructing aqueous humor outflow. Release of the traction by an incision (goniotomy or trabeculotomy) of the thickened meshwork may relieve the obstruction. Of uncertain pathological significance is that there are no vacuoles in the endothelium of Schlemm's canal and there is a broad layer of collagen and amorphous material in the juxtacanalicular connective tissue. The ciliary processes are elongated inward, as if they were pulled by zonular traction (perhaps created by an enlarging diameter of the limbus with a fixed lens diameter).

    An intensive particle monitoring study was conducted in homes in the Boston, Massachusetts, area during the winter and summer of 1996 in an effort to characterize sources of indoor particles. As part of this study, continuous particle size and mass concentration data were collected in four single-family homes, with each home monitored for one or two 6-day periods. Additionally, housing activity and air exchange rate data were collected. Cooking, cleaning, and the movement of people were identified as the most important indoor particle sources in these homes. These sources contributed significantly both to indoor concentrations (indoor-outdoor ratios varied between 2 and 33) and to altered indoor particle size distributions. Cooking, including broiling/baking, toasting, and barbecuing contributed primarily to particulate matter with physical diameters between 0.02 and 0.5 microm [PM((0.02-0.5))], with volume median diameters of between 0.13 and 0.25 microm. Sources of particulate matter with aerodynamic diameters between 0.7 and 10 microm [PM((0.7-10))] included sautéing, cleaning (vacuuming, dusting, and sweeping), and movement of people, with volume median diameters of between 3 and 4.3 microm. Frying was associated with particles from both PM((0.02-0.5)) and PM((0.7-10)). Air exchange rates ranged between 0.12 and 24.3 exchanges/hr and had significant impact on indoor particle levels and size distributions. Low air exchange rates (< 1 exchange/hr) resulted in longer air residence times and more time for particle concentrations from indoor sources to increase. When air exchange rates were higher (> 1 exchange/hr), the impact of indoor sources was less pronounced, as indoor particle concentrations tracked outdoor levels more closely.

    The majority of fibroblasts in alveolar septa are characterized by the presence of cytoplasmic bundles of microfilaments that contain cytoplasmic actin isoforms; these cells have been named contractile interstitial cells or V-type myofibroblasts. In the rat, they express desmin as intermediate filament protein. In this study, we explored the possibility that modulation and replication of such septal fibroblasts result in the appearance of alpha-smooth muscle (alpha-SM) actin-positive myofibroblasts, typical of lung fibrosis. Experimental pulmonary fibrosis was produced by a unique intratracheal instillation of bleomycin to 28 rats. Eight additional rats used as controls received the equivalent volume of saline. Paraffin and frozen sections of lungs were examined at days 1, 3, 5 and 7 after treatment. Microfilaments and intermediate filaments were stained using antibodies against total actin, alpha-SM actin, desmin, vimentin, keratin, and SM myosin. Electron microscopic labeling of desmin and alpha-SM actin using immunogold technique was done on Lowicryl K4M resin-embedded specimens. alpha-SM actin appeared in desmin-positive alveolar fibroblasts as early as 24 hours after intratracheal bleomycin instillation; the modulation of alpha-SM actin in these cells was preceded by a lymphomonocytic infiltration of alveolar septa. Twenty-four hours to 3 days after bleomycin administration, a proliferation of alveolar myofibroblasts occurred. Fibrosis with laying down of collagen fibers took place after the above mentioned cellular modifications. Our results support the view that septal fibroblastic cells can modulate into typical alpha-SM actin-containing myofibroblasts during experimental bleomycin-induced pulmonary fibrosis. In such a modulation a possible role of cytokines, particularly of transforming growth factor-beta, is considered.

    Alterations observed in the sarcoplasmic reticulum of muscle cells in left and right atrial myocardium from 10 patients with mitral valvular disease consisted of: a) proliferation of rough-surfaced endoplasmic reticulum, which formed large cisterns in perinuclear areas of hypertrophied cells and was considered indicative of increased protein synthesis; b) proliferation of free sarcoplasmic reticulum, a change that occurred in degenerated cells and appeared to be related to loss of contractile elements; c) two types of aggregates of tubules of free SR--one type was associated wtih abnormal Z-band material and was found only in cells showing loss of myofibrils and proliferation of free SR, whereas the other was not associated with either of these changes and occurred in less severely altered cells; and d) proliferation and enlargement of cisterns of extended junctional sarcoplasmic reticulum, which formed two distinct types of complexes: the first of these consisted of large, convoluted (Type A) cisterns that were wide (550 to 650 A in thickness) and did not have a central dense lamina; the second was composed of stacks of concentric or parallel (Type B) cisterns that were narrower (220 to 300 A in thickness), had a central dense lamina, and were separated from one another by layers of glycogen granules. The formation of these complexes of cisterns was regarded as an extreme form of overdevelopment of extended junctional sarcoplasmic reticulum in atrial muscle cells.

    Electron microscopic examination of 57 ocular melanomas (54 human, two feline and one canine) revealed the presence of viral particles in six specimens. Herpesviruses particles were observed in one human specimen and were passed in human fibroblasts (WI-38), where they gave rise to intranuclear inclusions. A-type oncornavirus particles (oncogenic RNA virus) were observed in a second case, both in cells of tumor directly removed from an enucleated eye as well as in cells grown in tissue culture. In three human specimens and one feline specimen, togavirus particles were observed. Rubella is a member of this group, and the possibility that the presence of togavirus in these tumors is the result of latent ocular infection by rubella virus is raised. Herpes virus and RNA tumor viruses are widely considered as having a possible etiologic role for certain human cancers. The observation of togavirus is unexpected, as this virus has not been previously implicated in human or animal tumors. Injection of an RNA tumor virus (Gardner strain feline sarcoma virus) into the anterior chamber of newborn kittens resulted in the development of iris and ciliary body melanomas, many of which showed invasion and, in one instance, metastasis. This is the first animal model of a viral-induced uveal melanoma, and the histology and ultrastructure are described. These results emphasize the need for the continued investigation of the role of these viruses in uveal melanoma.

    An experimental study of nematode endophthalmitis due to T canis and review of the literature has been presented. Six owl monkeys were infected either by nasogastric tube using embryonated T canis eggs or by carotid or intravitreal injection of second stage larvae. The clinical manifestations, especially ocular, were observed and various diagnostic tests performed. Only minimal or no intraocular changes were seen after systemic infection but significant abnormalities such as retinal hemorrhages and venous dilation were noted after intravitreal infection. Motile larvae were observed in the lenses of three eyes and in the vitreous of five eyes and, probably a sixth, after intravitreal injection. The intensity and timing of the intraocular reaction seemed to correlate with the infecting dose and apparent disappearance of larvae from the eye. Pathologic confirmation of larvae in the lens was obtained in one eye. A marked inflammatory reaction occurred in eyes receiving intraocular infection but none was seen in eyes with only systemic infectin. Various laboratory and serologic studies were performed, including the ELISA test, which were used to evaluate systemic as well as intraocular responses to infection with T canis. The two monkeys infected by nasogastric tube gave a positive ELISA response in the serum but intraocular fluids gave a negative response in all monkeys including those infected syst:mically and/or intraocularly. Problems in the understanding of clinical aspects of the disease, laboratory diagnosis and treatment are discussed. The need for future experimental studies is emphasized.

    The early development of the lipid-rich core and other features of atherosclerotic fibrous plaques has been elucidated by examining discrete, small regions of raised intima in human aorta, which often bear a resemblance to both fatty streaks and fibrous plaques. Approximately one-fourth of small raised lesions (less than 16 sq mm of surface area) contained little or no stainable lipid, while three-fourths had a characteristic appearance, which included a superficial layer of foam cells, a core of noncrystalline and/or crystalline lipid, and a developed or developing collagenous cap. Total intimal volumes of the lipid-containing lesions, termed "fibrolipid lesions," ranged from 3 to 43 microliters, with the majority less than 16 microliters. Core lipid in the smallest lesions was located in the musculoelastic layer of the intima. In larger lesions the core extended luminally into the elastic hyperplastic layer, and cholesterol crystals were found more frequently. Total cholesterol concentration in fibrolipid lesions was similar to that in fatty streaks; however, the ratio of unesterified to total cholesterol was relatively high, similar to that found in fibrous plaques. It is concluded that 1) the formation of a lipid-rich core and cholesterol crystallization are early events in the development of many raised lesions; 2) the consistent association between the superficial layer of foam cells and the deep-lying lipid-rich core raises the possibility of an influence, possibly indirect, of foam-cell lipid metabolism on core formation; and 3) the fibrolipid lesion may represent one stage in a potential transitional morphologic sequence between fatty streak and fibrous plaque.

    The late myocardial and vascular ultrastructural changes in rat hearts following consumption of the cardiovascular toxin allylamine were studied. Rats were given 0.1% allylamine HCl in drinking water for 10-104 days. From 10 to 21 days, there was organization of acute myocardial necrosis by macrophages and scattered polymorphonuclear leukocytes with prominent interstitial-cell proliferation. Alterations at 21-104 days included extensive scarring with formation of dense mature collagen with scattered fibroblasts present, grossly evident left-ventricular aneurysm, and gross and microscopic changes similar to those observed in the secondary form of endocardial fibroelastosis. Areas of scar contained highly cellular foci of smooth-muscle cells, myofibroblasts, and abundant extracellular elastin. Cardiac myocytes frequently showed markedly disorganized myofilaments, bizarrely distorted mitochondria with condensed cristae, and other severe degenerative changes. Small vessels within and adjacent to scar showed proliferation of intimal smooth-muscle cells. Endothelial lesions or recent or organized thrombi were not seen. Focal endocardial metaplasia, consisting of both chondroid and osseous tissue, was found in areas of transmural scarring, or ventricular aneurysm. Chondrocytes had the overall nuclear and cellular morphology, abundant rough endoplasmic reticulum, and surrounding lacunae typical of mature fibrocartilage. In some areas, the collagen matrix was undergoing calcification with the typical cross-banded pattern of calcifying connective tissue. Osteocytes were located in a densely calcified bone matrix and displayed characteristic cellular extensions into surrounding canaliculi. These findings indicate a severe myocardial, small-vessel, and endocardial injury during the course of chronic allylamine intoxication.

    The pathogenesis of acute respiratory bronchiolitis was examined in rhesus monkeys exposed to 0.8 ppm ozone fpr 4--50 hours. Epithelial injury and renewal was qualitatively and quantitatively characterized by correlated techniques of scanning and transmission electron microscopy as well as by light-microscopic autoradiography following labeling with tritiated thymidine. Extensive degeneration and necrosis of Type 1 epithelial cells occurred on the respiratory bronchiolar wall during the initial 4--12 hours of exposure. Increased numbers of labeled epithelial cells were present in this region after 18 hours of exposure, and the highest labeling index (18% was measured after 50 hours of exposure. Most (67--80%) of the labeled cells and all the mitotic epithelial cells (22) observed ultrastructurally were cuboidal bronchiolar epithelial cells. Of the labeled epithelial cells, 20--33% were Type 2 epithelial cells. After 50 hours of exposure the respiratory bronchiolar epithelium was hyperplastic. The predominant inflammatory cell in respiratory bronchiolar exudate was the alveolar macrophage. Monkeys that were exposed for 50 hours and allowed to recover in unozonized air for 7 days had incomplete resolution of respiratory bronchiolar epithelial hyperplasia. The results indicate that Type 1 epithelial cells lining respiratory bronchioles are the cell type most sensitive to injury and that both cuboidal bronchiolar epithelial cells and Type 2 epithelial cells function as stem cells in epithelial renewal.

    The phenomenon of fiber-induced cytotoxicity to P388D1 macrophagelike cells has been demonstrated to parallel (thus far without exception) the probability that the fiber will induce a pleural sarcoma (mesothelioma) in rats. This startling parallel in both cases seems to be essentially independent of the chemical nature of the fiber and correlates best with the presence of fibers greater than 8 micrometers in length and fibers with diameters in the range 0.5 to 1.0 micrometer (Stanton Hypothesis). In both systems evidence has been produced which cast strong doubts on any role played by absorbed (or adherent) impurities. The existence of multiple physical forms of the same chemical moiety (aluminum oxide, dihydroxy-sodium aluminum carbonate, borosilicate glass, etc.,) provides additional test material for the chemical independence corollary. The similar, cytotoxic or sarcomatogenous behavior of chemically different materials (e.g. amosite, chrysotile, aluminum oxide) exhibits the necessary converse argument. As long as the fiber size-shape dependency effect was limited to whole animal phenomena, such as tumor induction, one could make implicitly what were essentially statistical or probabilistic inferences involving transport and/or distribution of fibers to account for the physical effect. The demonstration of strict parallelism at the cellular level in vitro suggests the possibility that in the case of durable fiber toxicology we are dealing with a form of cell-solid interaction in which physical properties for which we have as yet no known receptors play a prominent role.

The mild accumulation of PMNs at the site of injury did not contribute significantly to the microvascular injury. The findings indicate that the unique changes in the microcirculation, not described before, may occur quite frequently, when the microvascular injury is elicited primarily by release of lysosomal constituents by phagocytic or nonphagocytic stimuli.

    The follicular structures present in the human pituitary gland were studied, at the light-microscopic level, using histochemical and immunocytochemical techniques. The antisera applied in the peroxidase-antiperoxidase procedure were anti-hFSH beta, anti-hLH beta, anti-hPRL, anti-hGH, anti-hTSH beta, anti-hLPH beta, anti-pACTH, and anti-hACTH. In the 10 normal pituitaries examined, follicles were always found in the three areas of the adenohypophysis. The wall of the pars distalis follicles showed the seven immunoreactive cell types studied, while follicle-stimulating hormone (FSH) and luteinizing hormone (LH) cells were the only ones present in the wall of the pars tuberalis follicles. Most of the cell types studied were also present in the wall of the intermediate area follicles, but these follicles had characteristics not found in the other two areas. They were very large, with frequent interconnections forming a three-dimensional network of anastomotic cavities, and the colloid had different histochemical affinity. None of the hormones studied could be detected by immunocytochemistry within the follicular colloid. Three of the ten pituitary adenomas examined showed numerous follicular structures. Some of the follicles in the adenomatous pituitaries were similar to those found in the normal adenohypophysis, but there were also follicles filled with only traces of colloid and numerous blood cells in the cavity, and follicles filled with neoformed connective tissue. In one of these cases, FSH/LH immunoreactive adenoma cells were seen in the wall of the follicles. The results obtained suggest that the finding of pituitary adenomas with follicular structures is not uncommon and that the follicles originate from the tumor cells. In addition, the follicles seem to have several functional stages, explaining the finding of different types of follicular formation.

    PURPOSE: Eduard Jaeger's original Test-Types were carefully evaluated: (1) to determine whether Jaeger had maintained a consistent standard, (2) to establish the correct Snellen equivalent for Jaeger's Test-Types, (3) to answer the question of why and how the standard was lost, and (4) to compare the visual angle of optotypes to lines of continuous text. METHODS: All original Viennese editions of Jaeger's Test-Types, as well as first generation United Kingdom (UK) and United States (US) versions, were evaluated. Data were collected objectively using a microruler with a 20X loupe and subjectively using a laser distance-measuring device. The data were analyzed using Microsoft Excel. All previous measurements of Jaeger's Test-Types, objective and subjective, collected over the past 133 years were compared to the current data and to each other. RESULTS: The correct Snellen equivalent of Jaeger's Test-Types was determined. The visual angle created from the measurement of the height of lowercase letters, without ascenders or descenders, provides an accurate method of assigning a visual angle of a line of continuous text. Comparing the typefaces used in printing first generation UK and US versions of Jaeger's Test-Types to the Viennese editions provided an explanation for the absence of a consistent standard for Jaeger's Test-Types today. CONCLUSIONS: All 10 versions of Jaeger's original Test-Types are virtually identical and established a gold standard for reading vision tests. Jaeger's standard was lost when his Test-Types were first printed in the UK and the US using local typefaces. The Jaeger standard has been re-established. Visual angles determined using continuous text are comparable to those obtained by using optotypes.

    Prevalence of psoriasis in Caucasians is estimated as 2 to 3 percent. Sound epidemiologic studies on a worldwide basis are needed to secure accurate prevalence rates for comparative purposes. Utilizing Stanford's psoriasis life histories records, the genetics of psoriasis has been explored by various means: statistical census data, pedigree analysis, and twin studies. This research suggests a multifactorial pattern of inheritance for psoriasis, implying that both genetic and environmental components are responsible for the manifestation of the disease. At present it is not possible to point to any single causative factor. Some of the suggested areas for research include study of uninvolved skin, growth control in the psoriatic lesion, viral causes, immunological aspects, and lipid metabolism.

    patients who have undergone anterior transposition surgery, the NFVB served as the ancillary origin of the IO. CONCLUSIONS: The name of the neurovascular bundle should be changed to the NFVB, since it has a prominent fibrocollagenous capsule and it is encased in fibrous tissue bands anteriorly. The NFVB has a linear course in the orbit from the apex to the IO muscle and is relatively stiff. The associated fibrous band extends posteriorly from the IO muscle capsule, encasing the nerve anteriorly and attaching 3 to 7 mm posteriorly into the capsule of the IR. The NFVB binds the mid posterior portion of the IO posteriorly. Its ligamentous qualities enable the NFVB to function as an ancillary origin for the IO.

However, it has not been definitively established what type of information is necessary for human risk assessment, whether currently toxicity testing methodologies are sufficient for fulfilling those needs, or whether treatment-induced tumorigenic responses in rodents are predictive of potential human risk. An alternative to the traditional bioassays are mechanism-based toxicology and molecular and cellular approaches, combined with comparative in vitro systems. These approaches might allow the rapid screen of chemicals for setting priorities for further studies to determine the dose-response relationship for chemical effects at low doses, to assess effects other than mutagenesis and/or tumorigenesis, or to establish qualitative and quantitative relationships of biomarkers to toxic effects. Until there is enough information on the predictive value of mechanism-based toxicology for risk assessment, this approach should be used in conjunction with and validated by the traditional in vivo long-term bioassays.

    -bank eyes and the theoretical analyses of this entity show that the pressure required to produce such an injury is much more easily obtained with a 3- or 5-mL syringe than with a syringe 10 mL or larger. CONCLUSIONS: Explosion of an eyeball during the injection of anesthesia for ocular surgery is a devastating injury that may go unrecognized. The probability of an ocular explosion can be minimized by careful use of a syringe 10 mL or larger with a blunt needle, by discontinuing the injection if resistance is met, and by inspecting the globe prior to ocular massage or placement of a Honan balloon. When ocular explosion occurs, immediate referral to and intervention by a vitreoretinal surgeon is optimal. Practicing ophthalmologists should be aware of this blinding but preventable complication of ocular surgery.

    limitation of versions, less separation of the tendons from sclera, and thicker appearance of the scar segments. The use of nonabsorbable sutures in the repair procedure reduced the recurrence rate. Histologic examination of the clinical stretched scar specimens showed dense connective tissue that was less well organized compared with normal tendon. In the tissue culture studies, cells cultured from the stretched scar specimens grew rapidly and were irregularly shaped. A high-molecular-weight protein was identified in the culture medium. By contrast, cells cultured from normal tendon (controls) grew more slowly and regularly, stopped growing at 4 days, and produced less total protein than cultured stretched scar specimens. In the animal model studies, the collagenase-treated sites showed elongated scars with increased collagen between the muscle and the sclera, as well as increased collagen creep rates, compared with the saline-treated controls. The use of nonabsorbable sutures in collagenase-treated animal model surgery sites was associated with shorter, thicker scars compared with similar sites sutured with absorbable sutures. CONCLUSIONS: A lengthened or stretched, remodeled scar between an operated muscle tendon and sclera is a common occurrence and is a factor contributing to the variability of outcome after strabismus repair, even years later. This abnormality may be revealed by careful exploration of previously operated muscles. Definitive repair requires firm reattachment of tendon to sclera with nonabsorbable suture support.

    Chiropractic education in the northwestern United States has its origins in the Marsh School & Cure in 1904. Most of the early schools were located in Portland, Oregon, including the D.D. Palmer College of Chiropractic (1908-1910), and several of these had merged by 1912 or 1913 to form the Pacific Chiropractic College, forerunner of today's Western States College. The latter was organized as a non-profit institution during the Great Depression, and struggled not only to survive but to create a higher standard. The early broad-scope of chiropractic training in the state probably encouraged the liberal scope of practice enjoyed in Oregon to this day.

    The present review focuses on the mouse as an experimental immunopathologic model for human non-Hodgkin's lymphomas and related leukemias. Immunomorphologic evidence is presented that clearly demonstrates that B- and T-cell subtypes of mouse (murine) lymphoma/leukemia closely resemble and are analogous to B- and T-cell subtypes of human lymphoma/leukemia as defined by recently proposed immunomorphologic classifications. Further evidence is presented that favors the hypothesis that certain types of murine and human B-cell lymphoma develop out of prodromal, prelymphomatous states, which exhibit antecedent morphologic and immunologic abnormalities. The many experimental advantages of the murine systems are stressed, as well as the concept that the presently defined immunomorphologic approach should be effectively combined with molecular and cytogenetic parameters.

    Patients with spina bifida have multiple ophthalmologic problems, many of which are preventable. Most of the problems are related to the hydrocephalus, which is caused by the coexisting Arnold-Chiari malformation. When patients are treated for hydrocephalus, and comprehensive eye care is available, 94% of the patients will have 6/12 visual acuity or better. Strabismus is common but it responds well to medical and surgical treatment. Children with spina bifida should have frequent examinations by an ophthalmologist who is familiar with the diagnosis and management of the defects recorded in this study.

    The length of the optic nerves is a reflection of normal postnatal cranio-orbital development. Unilateral elongation of an optic nerve has been observed in two patients with orbital and skull base neoplasms. In the first case as compared to the patient's opposite, normal optic nerve, an elongated length of the involved optic nerve of 45 mm was present. The involved optic nerve in the second patient was 10 mm longer than the normal opposite optic nerve. The visual and extraocular function was preserved in the second patient. The first patient had only light perception in the affected eye. In this paper, the embryology, anatomy, and physiology of the optic nerve and its mechanisms of stretch and repair are discussed.

Using this method, pneumoconioses may be distinguidhed from other pneumopathies. In cases of pneumoconiosis, there exists a specific relationship between the etiology of the dust exposure and the crystallographic characteristics of the intrapulmonary deposits. The nature of the deposits may be indicative of a specific type of pneumoconiosis. This method is particularly useful in differentiating between asbestos bodies and ferruginous bodies.

    Three methods by which electron diffraction may be applied to problems in electron microscopy are discussed from a fundamental point of view, and experimental applications with biological specimens are demonstrated for each case. It is shown that wide-angle electron diffraction provides valuable information for evaluating specimen damage that can occur either during specimen preparation or while in the electron beam. Dark-field electron microscopy can be used both to enhance the image contrast and to provide highly restricted and therefore highly specific information about the object. Low-angle electron diffraction provides quantitative information about the object structure in the range from 20 A to ∼ 1000 A. Lowangle electron diffraction also demonstrates the important role of Fourier contrast with biological specimens, which are usually characterized by structural features with dimensions of 20 A or larger.

Of the 13, three spent their professional lives exclusively in dental education, research, and public health. The remaining 10 were dental clinicians who served patients with competence, care, and concern. Additionally, they contributed to dentistry's image and progress by improving medicodental relations, pioneering in university dental education, engaging in philanthropy, qualifying for dental specialties, exerting leadership in dental professional organizations, integrating dentistry in hospital care, solving community health problems, and participating in all aspects of dental journalism. A sizable portion of their energies was expended in enhancing the quality of life in their communities and the nation.

The authors report the sequential growth, histology, tumor neovascularization, and vascular permeability of this tumor following its intracerebral implantation. Tumor angiogenesis correlates with the rapid and logarithmic intracerebral tumor growth. The proliferation of blood vessels in the tumor and the organization of tumor cells around tumor vessels are described. Breakdown of the blood-brain barrier (detected by Evans blue leakage) starts in the early stages of tumor development and becomes prominent as the tumor vasculature and size increase. This model is useful for experimental studies of angiogenesis. Images Figure 2 Figure 3 Figure 6 Figure 4 Figure 5 Figure 7 Figure 8 Figure 10 Figure 12 Figure 13 Figure 15 PMID:2451889

Experimental studies of animals were carried out to determine the significance of such changes by observing reactions that occur under carefully controlled conditions. A lesion with collagen deposition that was found in the centrolobular region of glomeruli sheds new light on the function of this region. This evidence must be considered in developing an understanding of how the production of urine is controlled.

    Using cryo-transmission electron microscopy, we have obtained abundant and reproducible evidence for a superstructure of dioleoylphosphatidylcholine (DOPC) bilayers. Dispersions of vesicles were prepared by gentle shaking of a 2% suspension of DOPC in water followed in part by extrusion through a porous technical membrane. Sampling and cryofixation took place at various times within 3 weeks after the preparation. From the micrographs we infer that the small fraction of vesicles enclosing one another develop passages (connections) between the bilayers. In contrast, the superstructure is basically a feature of disconnected membranes. Among its modifications are isolated membrane bends or folds and a grainy membrane texture with a minimal grain spacing of 4-6 nm. In the extruded dispersions the passages and the superstructure seem to be formed mostly within the first day. The fraction of smooth and unilamellar vesicles is large at all times and in all dispersions.

    One of the original principles of teratology states that, "Susceptibility to teratogenesis varies with the developmental stage at the time of exposure to an adverse influence" [Wilson JG. Environment and Birth Defects. New York:Academic Press, 1973]. The time of greatest sensitivity encompasses the period of organ formation during weeks 3-8 following fertilization in human gestation. At this time, stem cell populations for each organ's morphogenesis are established and inductive events for the initiation of differentiation occur. Structural defects of the heart and endocrine system are no exception to this axiom and have their origins during this time frame. Although the function and maturation of these organs may be affected at later stages, structural defects and loss of cell types usually occur during these early phases of development. Thus, to determine critical windows for studying mechanisms of teratogenesis, it is essential to understand the developmental processes that establish these organs.

    Group B Coxsackieviruses are a common cause of myocarditis. To detect the viral genome and its localization in the myocardium, we examined C3H/He mice with Coxsackievirus B3 (CVB3) myocarditis on days 5, 8, and 14 after inoculation by the reverse transcriptase polymerase chain reaction and by in situ hybridization. Sense and antisense CVB3 RNA were detected in the myocardium of all mice up to day 14 by reverse transcriptase polymerase chain reaction. Light microscopic in situ hybridization with a cDNA probe for CVB3 showed clusters of positive signals in the areas of myocardial necrosis and cell infiltration. With electron microscopic in situ hybridization, CVB3 RNA was detected in the cytoplasm of cardiocytes, between the myofibrils, near the mitochondria, and in tubular or vesicular structures. Viral RNA was also detected in necrotic debris, in the cytoplasm of macrophages, and in the cytoplasm of interstitial fibroblasts. These findings suggest that CVB3 RNA is replicated in the cytoplasm of cardiocytes, transferred into tubular or vesicular structures, released into the interstitium, and phagocytosed by macrophages. Some positive signals were also detected in the cytoplasm of cardiocytes showing close contact with infiltrating lymphocytes, suggesting that the lymphocytes recognized virus-infected cardiocytes and caused cell-mediated immune cardiocyte damage.

    Quantification of synaptophysinlike immunoreactivity is a valuable method for studying the presynaptic terminals in the normal and damaged nervous system. The present report shows that in the control brain, the predominant pattern of synaptic immunostaining in the neocortex was that of an evenly distributed densely granular immunolabeling of the neuropil, while in the paleocortex and in subcortical areas of the brain most of the presynaptic terminals were distributed along the dendritic arborizations or around the neuronal somata. The immunochemical and the immunohistochemical analysis of the Alzheimer's disease tissue showed that the frontal and parietal cortex presented the most severe and widespread loss, with a 45% loss in synaptophysin immunoreactivity. These areas showed an average 35% loss of large neurons. The visual cortex, hippocampus, entorhinal cortex, nucleus basalis of Meynert, and locus ceruleus displayed some degree of loss, but to a lesser extent. In addition to this loss, the basic patterns of organization of the presynaptic terminals were altered, with the presence of abundant, enlarged synaptophysin-labeled terminals. This study further supports the role of synaptic pathology in Alzheimer's disease. Images Figure 10 Figure 11 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 12 PMID:1899001

    Those microvascular endothelial events that parallel the evolution of platelet aggregation were evaluated in a well-controlled animal model. Cat pial microvessels were observed through a cranial window while local platelet aggregation was produced by intravenous injection of sodium fluorescein and simultaneous exposure of the pial vessels to light from a filtered mercury lamp that excited the fluorescein. The vessels were fixed in situ when the in vivo observations of a preselected vessel indicated early, intermediate, or advanced aggregation in that vessel. The preselected vessel was then harvested for ultrastructural study together with adjacent vessels from the illuminated field. These vessels and appropriate controls were compared in semiserial thin sections. The onset of platelet aggregation in both venules and arterioles was accompanied by focal endothelial lucency, vacuole formation, luminal membrane rupture, and swelling of the nuclear envelope. These changes were not found in control material. With intermediate aggregation these changes were more common, while with advanced aggregation these abnormalities occurred together with focal endothelial denudation. Thus, in this model denudation occurred only with advanced aggregation and was not a prerequisite for aggregation.

    Intravenous administration of disrupted Streptococcus mutans into rabbits over 23-76 weeks led to severe nephritis involving glomeruli, tubules, and interstitium. Light-microscopic observation of glomeruli documented diffuse endocapillary proliferative glomerulonephritis accompanied often (65%) by epithelial crescents. Electron-microscopic observation revealed humps in glomeruli of 70% of kidney specimens. In the glomeruli of some rabbits, extensive fibrin deposits and sclerosis were evident. Immunofluorescence showed linear, granular, often ribbonlike or patchy immune deposits encompassing, in order of decreasing frequency, C3, IgG, streptococcal antigen, IgA, and IgM. The histopathologic and immunohistologic features of the nephritis seen in rabbits given S mutans thus shows many features of Streptococcus-associated nephritides in man, in particular, the diffuse glomerular nephritis encountered in subacute bacterial endocarditis. Further, analysis of nephritis induced by administration of S mutans may have implications for the evaluation and purification of dental caries vaccines.

    Granulophysin, a protein described in platelet dense granule membranes, has been shown to be similar or identical to CD63, a lysosomal membrane protein. We have previously shown granulophysin to be present in neutrophils using immunofluorescence. We now localize granulophysin to the neutrophil azurophilic granules by fine structural immunocytochemistry. Granulophysin expression on the surface membrane of the neutrophil is increased following stimulation of the cells, demonstrated by flow cytometry and fine structural immunocytochemistry. A similar pattern is shown for an anti-CD63 antibody. Incubation of activated neutrophils with D545, a monoclonal antibody to granulophysin, blocks subsequent binding of anti-CD63 antibodies to the cell surface, and anti-CD63 antibodies prevent subsequent binding of D545 as assessed by flow cytometry and immunoblotting. Our results support the homology of CD63 and granulophysin previously demonstrated in platelets and confirm CD63 as an activation marker in neutrophils and the first azurophilic granule membrane marker of neutrophils.

    Gramicidin A, a hydrophobic linear polypeptide, forms channels in phospholipid membranes that are specific for monovalent cations. Nuclear Magnetic Resonance (NMR) spectroscopy provided the first direct physical evidence that the channel conformation in membranes is an amino terminal-to-amino terminal helical dimer, and circular dichroism (CD) spectroscopy has shown the sensitivity of its conformation to different environments and the structural consequences of ion binding. The three-dimensional structure of a gramicidin/cesium complex has been determined by x-ray diffraction of single crystals using single wavelength anomalous scattering for phasing. The left-handed double helix in this crystal form corresponds to one of the intermediates in the process of folding and insertion into membranes. Co-crystals of gramicidin and lipid that appear to have gramicidin in their membrane channel conformation have also been formed and are presently under investigation. Hence, we have used a combination of spectroscopic and diffraction techniques to examine the conformation and functionally-related structural features of gramicidin A.

    We examined the fluorescence spectral properties of the DNA stains DAPI (4′,6-diamidino-2-phenylindole, hydrochloride) and Hoechst 33342 (bis-benzimide, or 2,5′-bi-1H-benzimidazole2′-(4-ethoxyphenyl)-5-(4-methyl-1-piperazinyl)) with two-photon (2hν) and three-photon (3hν) excitation using femtosecond pulses from a Ti:sapphire laser from 830 to 885 nm. The mode of excitation of DAPI bound to DNA changed from two-photon at 830 nm to three-photon at 885 nm. In contrast, Hoechst 33342 displayed only two-photon excitation from 830 to 885 nm. DAPI-DNA displayed the same emission spectra and decay times for 2hν and 3hν excitation. Hoechst 33342-DNA displayed the same intensity decay for excitation at 830 and 885 nm. Both probes displayed higher anisotropies for multiphoton excitation as compared to one-photon excitation with ultraviolet wavelengths, and DAPI-DNA displays a higher anisotropy for 3hν at 885 nm than for 2hν at 830 nm. We used 970-nm excitation of DAPI-stained chromosomes to obtain the first three-dimensional images with three-photon excitation. Three-photon excitation of DAPI-stained chromosomes at 970 nm was demonstrated by the power dependence in the fluorescence microscope. ImagesFIGURE 10FIGURE 11FIGURE 12 PMID:9017187

    Molecular dynamics simulations have been performed on the glucocorticoid receptor DNA binding domain (GR DBD) in aqueous solution as a dimer in complex with DNA and as a free monomer. In the simulated complex, we find a slightly increased bending of the DNA helix axis compared with the crystal structure in the spacer region of DNA between the two half-sites that are recognized by GR DBD. The bend is mainly caused by an increased number of interactions between DNA and the N-terminal extended region of the sequence specifically bound monomer. The recognition helices of GR DBD are pulled further into the DNA major groove leading to a weakening of the intrahelical hydrogen bonds in the middle of the helices. Many ordered water molecules with long residence times are found at the intermolecular interfaces of the complex. The hydrogen-bonding networks (including water bridges) on either side of the DNA major groove involve residues that are highly conserved within the family of nuclear receptors. Very similar hydrogen-bonding networks are found in the estrogen receptor (ER) DBD in complex with DNA, which suggests that this is a common feature for proper positioning of the recognition helix in ER DBD and GR DBD.

    Secretion of glomerular cell-derived matrix metalloproteinases (MMPs) and their specific inhibitors, TIMP-1,2, may play an important role in the turnover of the glomerular extracellular matrix under basal and pathologic conditions. A 66-68 kd MMP secreted by cultured mesangial cells (MC) with activity against Type IV collagen and gelatin was purified and shown by amino-acid sequence analysis to be identical with a Type IV collagenase/gelatinase secreted by certain transformed tumor cell lines. The expression of the mesangial MMP in vivo was limited within the kidney to a small subset of the intrinsic glomerular mesangial cell population. After induction of acute anti-Thy 1.1 glomerulonephritis, there was a large increment in the number of Type IV collagenase-secreting MC, temporally coincident with the development of mesangial hypercellularity. The expression of the MMP inhibitor protein, TIMP-1, was not changed over this period. Ultrastructural studies localized the mesangial MMP to areas of evolving mesangiolysis and at sites of glomerular basement membrane disruption. Enhanced expression of the mesangial cell-derived Type IV collagenase may contribute to the evolution of glomerular injury in this model of immune complex-mediated glomerulonephritis or may be involved in the extensive matrix remodeling process that accompanies this form of glomerular injury.

    Fragments of tracheal epithelium alone or in continuity with connective tissues, can be maintained in culture medium and used for short term or long term studies of toxicity of a variety of chemicals. Large numbers of uniform cultures are prepared with the aid of a slicing device or by application of simple method for dissecting sheets of epithelium free from underlying cartilage. The cultures may be placed in an exposure chamber-incubator mounted on a microscope stage and monitored continually for ciliostasis and exfoliation of cells. Morphology is further studied by fixation of selected specimens and preparation for light microscopy and electron microscopy. Synthetic functions are evaluated by autoradiographic measurement of incorporation of radioactive precursors into macromolecules and other dynamic features are indirectly assessed by histochemical and histoenzymatic methods. Short-term studies using these several techniques have shown that ciliostasis does not correlate with cell injury in all instances, and a long-term study has demonstrated dose dependence of a cytotoxic agent when duration of culture viability is measured. The method lends itself to a broad range of investigations in which dose, period of exposure, and role of cofactors must be independently and quantitatively assessed. Images FIGURE 1. FIGURE 2.

    The central nervous system (CNS) has been examined at autopsy in 89 patients who died of the acquired immune deficiency syndrome (AIDS), including 14 patients who died primarily of neurologic complications of the disease. A total of 66 brains (74%) showed significant pathologic abnormalities, with opportunistic infections including cytomegalovirus (14) and cryptococcal (11) infections, progressive multifocal leukoencephalopathy (6), toxoplasmosis (6), and histoplasma microabscesses (1). Incidental Mycobacterium avium-intracellulare infection was found in 4 cases. Simultaneous CNS infection by more than one microorganism was encountered in 5 patients. Subacute (microglial nodule) encephalitis-related to cytomegalovirus infection or possibly brain infection by the causative agent of AIDS was present in 56 cases. Primary CNS lymphoma was noted in 3 patients. Secondary CNS deposits of lymphoma were found in 1 patient, and another patient had lymphomatoid granulomatosis. Vascular complications were not infrequently seen, and included infarcts secondary to vessel occlusion and disseminated intravascular coagulation in 4 patients and intracranial hemorrhage of variable severity in 13. White matter changes included vacuolar myelopathy (3 cases), central pontine myelinolysis (1 case), and foci of calcified, necrotizing leukoencephalopathy in pontocerebellar fibers of the basis pontis (2 cases). These findings highlight the variety of CNS complications in AIDS, some of which are not associated with clinical manifestations. Nevertheless, characterization of all lesions may be important in understanding the neurologic sequelae of AIDS.

    Antisense oligonucleotides have the ability to inhibit individual gene expression in the potential treatment of cancer and viral diseases. However, the way parenterally administered oligonucleotides distribute themselves into healthy tissues or tumors is poorly understood. In this study, the cell and tissue distribution of two modified or unmodified phosphodiester pentadeca-beta-oligonucleotides intravenously administered to healthy or tumor-bearing nude mice was assessed by autoradiography as well as by direct fluorescence and immunoenzymatic histological methods. Resistance of oligonucleotides to degradation by nuclease activity was previously studied in vitro. Using these methods we were able to show the following: 1) within minutes, oligonucleotides permeate all cells and tissues with the exceptions of erythrocytes and intervertebral discs; 2) cell and tissue distribution does not depend on the sequence of the given oligonucleotide; 3) concentration of oligonucleotides is higher within the connective tissue cells than in the interstitial matrix; 4) after uptake, oligomers partition throughout all of the cellular compartments, including at the highest intracellular concentrations in the nuclei; 5) oligonucleotides penetrate easily the tumor cell compartments, oligonucleotide diffusion being unimpeded by the extracellular matrix.

    Treatment of F344 rat alveolar macrophages (AMs) in vitro with cell-free supernatant fluids obtained from concanavalin-A (Con A)-stimulated syngeneic lymphocytes induced extensive fusion. The lymphokine responsible for the fusion of AMs (but not other cells) is here referred to as AM fusion factor (Con-A-MFF). Fusion is dependent on the dose of Con-A-MFF and the population density of AM cultures and occurred 10 hours after Con-A-MFF was added to cultures of normal AMs. Con-A-MFF must interact with AMs for more than 8 hours before full expression of fusion is reached at 24 hours. Using a technique allowing for sequential scanning to transmission electron microscopy analysis of cells, the authors determined the relationship of the morphologic characteristics of the surface and the internal structure of cells fusing to form multinucleate giant cells (MGCs). The process of AM fusion begins with the aggregation of AMs, followed by interdigitation of cell processes. Serial sections of MGCs showed lysosomes associated with remnants of plasma membrane in the cytoplasm. The MGCs contained numerous organelles associated with increased secretory activity of cells.

    Formalin-fixed paraffin-embedded tumor tissues from North American (N = 12) and Japanese (N = 11) patients with lung carcinomas were stained by the immunoperoxidase method for surfactant-specific apoprotein. Cytoplasmic and focal nuclear staining was seen in three "bronchioloalveolar carcinomas" occurring in Japanese patients. We refer to these three tumors as carcinomas of Type II pneumocytes. These neoplasms formed discrete masses with minimal growth along the alveolar septa at margins of the tumors. Papillary growth with lymphocytic infiltrates in the stalks of the papillary processes was the usual growth pattern. Focal noncaseating granulomas were seen in the stroma of 2 cases, and similar granulomas in the draining lymph nodes were noted in 1. The abundant cytoplasm was foamy, and the nuclei were generally vacuolated with frequent eosinophilic inclusions in the vacuoles. By electron microscopy, osmiophilic lamellar bodies or whorled lamellas were seen in the cytoplasm of the 3 tumors staining for surfactant apoprotein. The nuclei in 2 of the 3 cases contained tubular inclusions; the tubules had a diameter of 60 nm and a 20-nm core.

    A series of field studies was conducted between 1979 and 1985 in Puget Sound, Washington State, to investigate etiological relationships between prevalences of hepatic neoplasms in bottom-dwelling marine fish species, with emphasis on English sole (Parophrys vetulus), and concentrations of toxic chemicals in sediments and affected fish. Statistically significant (p less than or equal to 0.05) correlations have been found between the prevalences of hepatic neoplasms in English sole and the following parameters: sediment concentrations of aromatic hydrocarbons, and concentrations of the metabolites of aromatic compounds in the bile of affected sole. A significant difference (p less than 0.001) was also found between the relative concentrations of aromatic free radicals in the liver microsomes of English sole with liver lesions compared to sole without liver lesions. Laboratory studies designed to evaluate the etiology of the liver neoplasms in English sole have also yielded evidence that is consistent with the view that high molecular weight aromatic hydrocarbons, e.g., benzo[a]pyrene (BaP), are hepatocarcinogens in English sole. The current status of a series of long-term (up to 18 months) exposures of English sole and rainbow trout (Salmo gairdneri) to selected fractions of Puget Sound sediment extracts, enriched with aromatic hydrocarbons and nitrogen-containing aromatic compounds, and to individual carcinogens (e.g., BaP) is discussed.

    Polychlorinated biphenyls (PCB) produced ultrastructural lesions in thyroid follicular cells and reductions in serum thyroxine levels in rats that were time- and dose-dependent. The acute effects (4 week) of PCB (50 and 500 ppm) consisted of an accumulation of lysosomal bodies and colloid droplets in follicular cells with abnormalities of microvilli on the luminal surface. The chronic administration (12 week) of PCB (50 and 500/250 ppm) resulted in a striking distention of many follicular cells with large lysosomal bodies with strong acid phosphatase activity and colloid droplets, blunt and abnormally branched microvilli, and mitochondrial vacuolation. These ultrastructural alterations in follicular cells were associated with a highly significant reduction in serum thyroxine with both the low and the high dose of PCB. Follicular cells remained responsive to the lowered thyroxine level after feeding PCB for 4 and 12 weeks and underwent moderate compensatory hypertrophy and hyperplasia. Thyroid follicles were smaller than in controls and were lined by more columnar cells that occasionally formed papillary projections into the colloid. Residual ultrastructural alterations persisted for 12 weeks following cessation of feeding the compound, and serum thyroxine levels were significantly lower than in control rats. However, 35 weeks after discontinuing PCB, thyroid follicular cells were similar to those in controls and serum thyroxine levels had returned to normal. The striking ultrastructural lesions in follicular cells produced by feeding PCB to rats appeared to contribute to the lowering of serum thyroxine levels, in combination with the known stimulation of peripheral thyroxine metabolism by these compounds. Certain metabolic alterations produced by PCB intoxication in experimental animals and human beings may be related to an alteration in thyroid function.

    Immunization of rabbits with physicochemically altered homologous or even autologous IgG induces formation of antibodies combining with IgG of rabbit and of foreign species. Cardiac but not renal lesions were reported in such animals. This study examined the nephritogenic potential of the immune response to cationized or heat-aggregated homologous IgG of b9 or b4 allotype in rabbits of the b4 allotype. Rabbits injected with either b9 or b4 cationized IgG produced antibodies reactive with rabbit and human IgG and with histones; they also developed abnormal glomerular deposits of IgG b4 and C3 corresponding to alterations of the glomerular basement membranes (GBM). Rabbits injected with either b9 or b4 aggregated IgG developed antibodies reactive with rabbit and human IgG and abnormal glomerular deposits of IgG b4 and C3 in the GBM and in the mesangium with subendothelial and mesangial electron-dense deposits. Some rabbits in both groups had proliferative and exudative glomerulonephritis and proteinuria. The results showed that immunization of rabbits with physicochemically altered homologous IgG induces an immune response to rabbit and human IgG and to histones as well as glomerular deposits of autologous IgG and C3 and other glomerular lesions.

    The pathophysiologic events in optic nerve axons have recently been recognized as crucial to an understanding of clinically significant acquired alterations in the ophthalmoscopic appearance of the optic disc. Stasis and related abnormalities of axonal transport appear to explain most aspects of optic nerve head swelling, including optic disc drusen and retinal cottonwool spots. Loss of axoplasm and axonal death can be invoked to interpret optic disc pallor, thinning and narrowing of rim tissue, changes in the size and outline of the optic cup, laminar dots, atrophy of the retinal nerve fiber layer, and acquired demyelination and myelination of the retinal nerve fiber layer. It is speculated that the axons may also play a role in the mechanical support of the lamina cribrosa in resisting the pressure gradient across the pars scleralis of the optic nerve head. Axons and their associated glial cells may be involved in those cases where "reversibility" of cupping of the optic disc has been reported. The structure, physiology, and experimental pathologic findings of the optic nerve head have been reviewed. Many aspects concerning the final anatomic appearance of the optic nerve head have been explained. However, many questions remain concerning the intermediate mechanisms by which increased intracranial pressure retards the various components of axonal transport in papilledema and by which increased IOP causes axonal loss in glaucoma. Investigation of the molecular biology of axonal constituents and their responses to abnormalities in their physical and chemical milieu could extend our understanding of the events that result from mechanical compression and local ischemia. Moreover, we have identified a need to further explore the role of axons in the pathophysiology of optic disc cupping.

    Extrinsic allergic alveolitis and pulmonary sarcoidosis are granulomatous diseases of the lung for which clinical presentation and anatomic site of granuloma formation differ. Extrinsic allergic alveolitis is caused by inhaled antigens, whereas the nature and source of the inciting antigen in sarcoidosis is unknown. To test the hypothesis that the route via which antigen is introduced to the lung contributes to the clinicopathological presentation of pulmonary granulomatous disease, rats immunized with intravenous (i.v.) Corynebacterium parvum were challenged after 2 weeks with either intratracheal (i.t.) or i.v. C. parvum. The granulomatous inflammation elicited by i.t. challenge predominantly involved alveolar spaces and histologically simulated extrinsic allergic alveolitis. In contrast, the inflammation induced by i.v. challenge was characterized by granulomatous angiitis and interstitial inflammation simulating sarcoidosis. Elevations of leukocyte counts and TNF levels in bronchoalveolar fluid, which reflect inflammation in the intra-alveolar compartment, were much more pronounced after i.t. than after i.v. challenge. Tumor necrosis factor, interleukin-6, CC chemokine, CXC chemokine, and adhesion molecule mRNA and protein expression occurred in each model. In conclusion, i.t. or i.v. challenge with C. parvum in sensitized rats caused pulmonary granulomatous inflammation that was histologically similar to human extrinsic allergic alveolitis and sarcoidosis, respectively. Although the soluble and cellular mediators of granulomatous inflammation were qualitatively similar in both disease models, the differing anatomic source of the same antigenic challenge was responsible for differing clinicopathological presentations.

    Although hyaline arteriolosclerosis is very common and has been of interest to pathologists for well over 100 years, its pathogenesis has never been determined. This study demonstrates that iC3b bound via an ester linkage to hydroxyl groups on the repeating disaccharide units of hyaluronic acid is a major component of arteriolar hyaline. The deposition of iC3b within the walls of arterioles appears to be due to slow spontaneous activation of the alternative complement pathway and random binding of metastable C3b to proximate hyaluronic acid within the arteriolar wall. Since hyaluronic acid does not activate the alternative complement pathway, bound C3b is rapidly inactivated by factors I and H to iC3b, which, along with factor H, remains bound to hyaluronic acid. The hyaline in some hyalinized arterioles also contains IgM and early and late classical complement pathway components. Indirect evidence suggests that the IgM represents immunoconglutinin, an autoantibody to neoantigens on iC3b and that their interaction results in activation of the classical complement pathway. The gradual accumulation of iC3b, factor H, and, at times, IgM and classical complement pathway components within the walls of arterioles is considered to be a physiologic consequence of aging and probably cannot be prevented, because interruption of the initial binding of metastable C3b to hyaluronic acid would require abrogation of the critically important functions of the alternative complement pathway.

    Objective: To demonstrate the response to a proprioceptive training model during a 1-week rehabilitation regime. The techniques were demonstrated on a college-aged female basketball player who had injured her anterior cruciate ligament (ACL) several weeks earlier. The athlete was tested, trained, and then retested during her semester break. Background: The ACL injury has become a fairly common occurrence in the world of athletics. Knowing this, the athletic trainer is constantly searching for ways to improve the rehabilitative process. New research demonstrates that rehabilitation should be based on proprioception. The ACL not only serves a mechanical role by limiting passive knee mobility but also serves a sensory role through the mechanoreceptors deep in its tissue, which communicate with the neuromuscular system to provide proprioceptive feedback during training and competition. Differential Diagnosis: Partial or complete tear of the ACL. Treatment: The athlete was treated with a rehabilitation protocol based on proprioception, which uses reactive neuromuscular training. Uniqueness: Our rehabilitation focused on the muscular imbalances about the hip, knee, and ankle. The athlete achieved dramatic decreases in muscular imbalances about the hip and knee in only 1 week of rehabilitation through reactive neuromuscular training. Conclusions: The athlete had significant gains in strength over her brief period of therapy. However, these gains can be viewed only as neuromuscular changes and not strictly as gains in strength. The athlete returned to postseason competition under the supervision of her surgeon, who later recommended surgical reconstruction at the completion of the basketball season with rehabilitation during the offseason.

    Potassium bromate (KBrO3) is an oxidizing agent that has been used as a food additive, mainly in the bread-making process. Although adverse effects are not evident in animals fed bread-based diets made from flour treated with KBrO3, the agent is carcinogenic in rats and nephrotoxic in both man and experimental animals when given orally. It has been demonstrated that KBrO3 induces renal cell tumors, mesotheliomas of the peritoneum, and follicular cell tumors of the thyroid. In addition, experiments aimed at elucidating the mode of carcinogenic action have revealed that KBrO3 is a complete carcinogen, possessing both initiating and promoting activities for rat renal tumorigenesis. However, the potential seems to be weak in mice and hamsters. In contrast to its weak mutagenic activity in microbial assays, KBrO3 showed relatively strong potential inducing chromosome aberrations both in vitro and in vivo. Glutathione and cysteine degrade KBrO3 in vitro; in turn, the KBrO3 has inhibitory effects on inducing lipid peroxidation in the rat kidney. Active oxygen radicals generated from KBrO3 were implicated in its toxic and carcinogenic effects, especially because KBrO3 produced 8-hydroxydeoxyguanosine in the rat kidney. A wide range of data from applications of various analytical methods are now available for risk assessment purposes. Images FIGURE 1. FIGURE 2. FIGURE 5. FIGURE 6. FIGURE 7. FIGURE 8. FIGURE 9.

The major goal was to study differences between the locomotion of wild-type cells and strains of triple mutants deficient in two F-actin cross-linking proteins (alpha-actinin and the 120-kDa gelation factor) and one F-actin fragmenting protein (severin). The size of contact area, AC, of both wild-type and mutant cells fluctuates between minimum and maximum values on the order of minutes, pointing toward an intrinsic switching mechanism associated with the mechanochemical control system. The fluctuation amplitudes are much larger on freshly cleaved mica than on glass. Wild-type and mutant cells exhibit remarkable differences on mica but not on glass. These differences comprise the population median of AC and alterations in pseudopod protrusion. AC is smaller by a factor of two or more for all mutants. Pseudopods protrude slower and shorter in the mutants. It is concluded that cell shape and pseudopods are destabilized by defects in the actin-skeleton, which can be overcompensated by strongly adhesive substrata. Several features of amoeboid cell locomotion on substrata can be understood on the basis of the minimum bending energy concept of soft adhering shells and by assuming that adhesion induces local alterations of the composite membrane consisting of the protein/lipid bilayer on the cell surface and the underlying actin-cortex.

    Eight pairs of young adult rats were pair-fed a high fat-low protein diet and ethanol or isocaloric glucose by permanent intragastric cannula for up to 6 months. Biopsies of the liver were taken monthly and the fibrosis was quantitated morphometrically using the sirius red polarization method of collagen visualization by light microscopy. Morphometric analysis of the sinusoids and scars were performed on electron micrographs made from the liver biopsies. An increase in the collagen in both the central and portal areas was found when the livers of the alcohol-fed rats were compared with controls. The predominant cell in the scars was the Ito cell. An increase in the percentage of the total Ito cell square area made up of rough endoplasmic reticulum (RER) was noted when the sinusoids of the liver of the ethanol-fed rats were compared with controls. No difference in the RER was found when the sinusoidal Ito cells were compared with the Ito cells located within the scars of the ethanol-fed rats. It was concluded that Ito cell "activation" by chronic ethanol feeding in the sinusoids of rats accurately predicts "activation" of the Ito cells within scars. The Ito cells are diffusely activated even though the scarring is localized. This implies that local factors as well as Ito cell activation are necessary for scar formation. In the case of alcoholic liver disease, scar formation may be initiated by centrilobular necrosis.

    The ultrastructural organization of ruthenium red (RR) stainable material within small blood vessels located in the limbus of the rabbit eye was studied. Proteoglycans were identified in this material by digesting tissues with Streptomyces hyaluronidase, testicular hyaluronidase, chondroitinase ABC, or heparinase before ruthenium red staining. Neuraminidase digestion enabled separate identification of sialoglycoprotein. The luminal surface of endothelial cells demonstrates an RR-stained glycocalyx containing both sialoglycoprotein and proteoglycans, which are removed by testicular hyaluronidase and crude heparinase. The basal coat of endothelial cells and small granules (10-20 nm in diameter) located within the basal lamina stain with RR and are removed only by crude heparinase. The surface coat of smooth muscle cells and small granules (10-20 nm) within their basal laminas are also digested by crude heparinase. Large proteoglycan granules (20-50 nm), which are completely removed by testicular hyaluronidase and partially digested by Streptomyces hyaluronidase, are deposited between the connective tissue fibers of the media and adventitia. Other large granules that are attached to collagen fibers contain enzyme-resistant anionic materials. The surface coat of adventitial fibroblasts is removed only by crude heparinase. Thin filaments (3-5 nm in diameter) interconnect the cell coat material, basal lamina granules, and large connective tissue granules, to form a network of proteoglycans that traverses the intima, media, and adventitia. The highly ordered arrangement of proteoglycans in the microvascular wall suggests that these macromolecules play several roles in microvascular function.

  18. The eye in the Marfan syndrome.

    PubMed Central

    Maumenee, I H

    1981-01-01

    One hundred sixty consecutive patients with the Marfan syndrome were reviewed for ocular, cardiovascular, and skeletal abnormalities, and were graded by severity. The most striking ocular abnormality was enlargement of the globe, presumably caused by scleral stretching. Staphylomata were not a feature of any of the patients seen, nor was keratoconus. The cornea, in fact, was flattened but not thinned. Among the 160 patients, 193 eyes showed dislocation of the lens. Dislocation of the lens was positively correlated with increased ocular axial length and with decreasing KJ readings. We postulate that the ocular pathologic changes are primarily caused by stretching of the tunica scleralis, and that the zonular fibers (thus under stress may "give" or may rupture in their area of presumably least density which may be the area of developmental fusion of the optic vesicle. In a small proportion of cases the lens dislocation was progressive. There was no correlation between ocular findings, on one hand, and the skeletal and cardiovascular abnormalities on the other. However, there was a good degree of intrafamilial consistency with regard to absence or presence of ocular pathology. The absence of correlation between the ocular and systemic findings in our data on these 160 patients is best explained by the existence of more than 1 point mutation, which may give rise to different but clinically similar phenotypes. The results of our calculations of mutation rate were compatible with such an explanation.

    1994-01-01

    In prior work we demonstrated the implementation of logic gates, sequential computers (universal Turing machines), and parallel computers by means of the kinetics of chemical reaction mechanisms. In the present article we develop this subject further by first investigating the computational properties of several enzymatic (single and multiple) reaction mechanisms: we show their steady states are analogous to either Boolean or fuzzy logic gates. Nearly perfect digital function is obtained only in the regime in which the enzymes are saturated with their substrates. With these enzymatic gates, we construct combinational chemical networks that execute a given truth-table. The dynamic range of a network's output is strongly affected by "input/output matching" conditions among the internal gate elements. We find a simple mechanism, similar to the interconversion of fructose-6-phosphate between its two bisphosphate forms (fructose-1,6-bisphosphate and fructose-2,6-bisphosphate), that functions analogously to an AND gate. When the simple model is supplanted with one in which the enzyme rate laws are derived from experimental data, the steady state of the mechanism functions as an asymmetric fuzzy aggregation operator with properties akin to a fuzzy AND gate. The qualitative behavior of the mechanism does not change when situated within a large model of glycolysis/gluconeogenesis and the TCA cycle. The mechanism, in this case, switches the pathway's mode from glycolysis to gluconeogenesis in response to chemical signals of low blood glucose (cAMP) and abundant fuel for the TCA cycle (acetyl coenzyme A).

The occurrence of a population of cells with several functional and structural features of macrophages among the lipid-laden cells of experimental diet-induced arterial lesions suggests that some foam cells may be derived from monocytes. An alternative explanation, that metabolically altered autochthonous arterial wall cells assume one or more characteristics of mononuclear phagocytes is less likely, since some of the markers used in these experiments are unrelated. Both explanations deserve further careful study. Images Figure 1 Figure 2 Figure 3 Figures 4-7 Figures 8-11 Figure 12 Figure 13 Figures 14-16 PMID:6772035

These mast cells were readily degranulated by monoclonal anti-DNP-BSA IgE, and the antigen, releasing 90% of the histamine. The study shows that mucosal mast cells formation from 'large lymphoid-like' cells present in the blood and in the lymph, is stimulated by TCF. The condensation of the metachromatic material and histamine synthesis depends on other cells, presumably fibroblasts which comprise the principal cell in the embryonic skin monolayers. The mechanism of the fibroblast influence is not yet known. Images Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 Figure 12 PMID:6186596

    further study. Specimens from patients with intraocular hemorrhage should be viewed cautiously, since erythrocytes contain high levels of enolase. Analysis of subretinal aspirates is an extremely accurate method of confirming the diagnosis of Coats' disease. The key diagnostic findings are the presence of cholesterol crystals and pigment-laden macrophages and the absence of tumor cells on fresh preparations. The technique should be reserved for patients where retinoblastoma has been ruled out by all noninvasive means and massive subretinal drainage is anticipated. The natural progression in advanced Coats' disease is toward the development of a blind, painful eye. Spontaneous regression does rarely occur, and some eyes quietly progress to a phthisical state.(ABSTRACT TRUNCATED AT 400 WORDS) Images FIGURE 2 FIGURE 3 FIGURE 4 A FIGURE 4 B FIGURE 5 FIGURE 6 FIGURE 7 FIGURE 8 FIGURE 9 FIGURE 10 FIGURE 11 FIGURE 13 FIGURE 14 FIGURE 15 FIGURE 16 FIGURE 17 FIGURE 18 FIGURE 19 FIGURE 20 FIGURE 21 FIGURE 22 FIGURE 23 FIGURE 24 FIGURE 25 FIGURE 26 FIGURE 27 FIGURE 28 FIGURE 29 FIGURE 30 FIGURE 31 FIGURE 32 FIGURE 33 FIGURE 34 A FIGURE 34 B FIGURE 35 FIGURE 36 FIGURE 38 FIGURE 39 FIGURE 41 FIGURE 42 FIGURE 43 FIGURE 44 FIGURE 45 FIGURE 46 A FIGURE 46 B FIGURE 47 A FIGURE 47 B FIGURE 48 A FIGURE 48 B FIGURE 49 FIGURE 50 FIGURE 51 FIGURE 52 FIGURE 54 FIGURE 54 (cont.)

    chiasm. It forms gradually over a period of years following monocular enucleation, presumably from shrinkage of the optic chiasm caused by atrophy of fibers from the enucleated eye. Therefore, the superior temporal hemianopia in the "other eye" seen in the anterior chiasmal syndrome cannot be due to compression of Wilbrand's Knee. I propose that it occurs from combined compression of the optic chiasm and one (or both) optic nerves.

    authors found no mRNA for the MCSF receptor, c-fms, in cultured EC or SMC macrophages are likely the primary target for MCSF within atheromatous vessels. The authors therefore investigated the effects of MCSF on monocyte functions related to foam cell development. Treatment of cultured human monocytes with recombinant human MCSF (10(3) U/ml, 72 hr) led to the accumulation of mRNA for the acetyl-LDL (scavenger) receptor and apolipoprotein E (apo E). These studies establish that vascular EC and SMC produce substantial MCSF in response to a variety of stimuli. The local production of MCSF during atherogenesis may contribute to macrophage survival and proliferation or activate specific macrophage functions such as expression of the scavenger receptor and secretion of apo E.

    The architecture of the present invention has been driven by the need to solve the beam quality problems inherent in Brewster's angle tipped slab lasers. The entrance and exit faces of a solid state slab laser are cut perpendicular with respect to the pump face, thus intrinsically eliminating distortion caused by the unpumped Brewster's angled faces. For a given zigzag angle, the residual distortions inherent in the remaining unpumped or lightly pumped ends may be reduced further by tailoring the pump intensity at these ends. 11 figures.

The goals of these developments have been the search for ideal permselective polymeric materials, techniques for producing ultrathin membrane layers free of imperfections and transforming gelled reverse osmosis membranes into solid gas permeation membranes. A novel approach to meeting the basic requirements of high permselectivity is attempted by altering the physical polymer structure within the membrane prior to application for gas separation. The influence of these physical interactions on membrane properties is presented. 47 references, 11 figures, 6 tables.

    A sudden excitation event of the Chandler wobble should induce the earth's rotation pole to undergo damped harmonic motion. This type of motion has been searched for in the observations of the Chandler wobble using techniques based upon the concept of a matched filter. Although the signal detection techniques used here were not sensitive enough to detect any such isolated sudden excitation events; the result that was obtained is consistent with a randomly excited model of the Chandler wobble. 16 references, 11 figures, 1 table.

    Besides EDTA and cysteine, cystine and penicillamine are the best collagenase inhibitors. The collagenase is produced by the leucocytes. The action mechanism of the collagenase inhibitors is due to the chelation of Zn ions. The best clinical indications for collagenase inhibitors are punctate epithelial keratitis, chemical burns, recurrent corneal erosions in keratoconus, trophic postinfectious ulcerations of the cornea (metaherpetic ulcers), and descemetoceles.

    Kustom, R.L.; Fuja, R.E.

    In an inductor-convertor circuit for transferring electrical energy between a storage coil and a load coil through a storage thyristor bridge, a load thyristor bridge, and a set of commutating capacitors, operation is improved by a method of changing the rate of delivery of energy in a given direction. The change in rate corresponds to a predetermined change in phase angle between the load bridge and the storage bridge, and comprises changing the phase of the bridge by two steps, each equal to half the predetermined change and occurring 180/sup 0/ apart. The method assures commutation and minimizes imbalances that lead otherwise to overvoltages. 11 figures.

    An improved method and assembly for attaching sputtering targets to cathode assemblies of sputtering systems which includes a magnetically permeable material is described. The magnetically permeable material is imbedded in a target base that is brazed, welded, or soldered to the sputter target, or is mechanically retained in the target material. Target attachment to the cathode is achieved by virtue of the permanent magnets and/or the pole pieces in the cathode assembly that create magnetic flux lines adjacent to the backing plate, which strongly attract the magnetically permeable material in the target assembly. 11 figures.

    Temperature-insensitive, phase-matched harmonic frequency conversion of laser light at a preferred wavelength of 1.064 microns can be achieved by use of a crystal of deuterated l-arginine phosphate. The crystal is cut and oriented so that the laser light propagates inside the crystal along one of several required directions, which correspond to a temperature-insensitive, phase-matching locus. The method of measuring and calculating the temperature-insensitive, phase-matching angles can be extended to other fundamental wavelengths and other crystal compositions. 12 figures.

Among the organisms used in the experiment, Daphnia magna (a cladoceran) and young carp (Cyprinus carpio) have proved to be more sensitive. Tubifex tubifex (an oligochaete) have proved to be more resistant. Taking in account the toxicity of geothermal waters with addition of a specific smell and taste contracted by the meat fish, their overflow into natural receivers is not recommended. 7 references, 12 figures.

    Based on a combination of Walther's Law of Facies and bed-form climb theory, the authors propose a model that explains how erosion surfaces and vertical sequences of clastic strata are preserved where deposition occurs in channelized or locally erosional environments including fluvial and submarine-channel deposits, barred beaches, and transgressive coastlines. the model considers both lateral and vertical migration of a scour surface and its associated depositional products. As in studies of bed-form climb, they recognize subcritical, critical, and supercritical climb of scour surfaces relative to adjacent depositional forms. 12 figures.

    A system and method for exchanging tools and end effectors on a robot permits exchange during a programmed task. The exchange mechanism is located off the robot, thus reducing the mass of the robot arm and permitting smaller robots to perform designated tasks. A simple spring/collet mechanism mounted on the robot is used which permits the engagement and disengagement of the tool or end effector without the need for a rotational orientation of the tool to the end effector/collet interface. As the tool changing system is not located on the robot arm no umbilical cords are located on robot. 12 figures.

    An in-vitro dissolution study was conducted on two respirable oxidized depleted uranium samples. The dissolution rates generated from this study were then utilized in the International Commission on Radiological Protection Task Group lung clearance model and a lung clearance model proposed by Cuddihy. Predictions from both models based on the dissolution rates of the amount of oxidized depleted uranium that would be cleared to blood from the pulmonary region following an inhalation exposure were compared. It was found that the predictions made by both models differed considerably. The difference between the predictions was attributed to the differences in the way each model perceives the clearance from the pulmonary region. 33 references, 11 figures, 9 tables.

    1983-01-01

    By using interactive computer graphics (ICG) it is possible to discuss the numerical aspects of some arms race issues with more specificity and in a visual way. The number of variables involved in these issues can be quite large; computers operated in the interactive, graphical mode, can allow exploration of the variables, leading to a greater understanding of the issues. This paper will examine some examples of interactive computer graphics: (1) the relationship between silo hardening and the accuracy, yield, and reliability of ICBMs; (2) target vulnerability (Minuteman, Dense Pack); (3) counterforce vs. countervalue weapons; (4) civil defense; (5) gravitational bias error; (6) MIRV; (7) national vulnerability to a preemptive first strike; (8) radioactive fallout; (9) digital-image processing with charge-coupled devices. 17 references, 11 figures, 1 table.

    Butala, S.W.

    1984-10-11

    When Fermilab was designed in the late 1960's and early 1970's, it was anticipated that Neutrino target train servicing could be costly in terms of personnel radiation exposure. This was based in part on the expectation that target intensities of at least 1E13 protons/pulse would be required to produce several neutrino interactions in a large bubble chamber detector. This was indeed later proven to be the case and historically the Neutrino beamline has been targeted with about one half of the protons available from the Main Ring. It was believed that much of the occupational radiation dose from the Neutrino Area could be spared by utilization of a remote manipulator system, which was eventually installed. It is the purpose of this report to examine the use of the Fermilab remote manipulator system and evaluate its cost effectiveness and success as an ALARA (As Low As Reasonably Achievable) tool. 16 references, 11 figures.

    Khounsary, A.M.

    1994-02-15

    A double crystal monochromator is described including two identical, parallel crystals, each of which is cut such that the normal to the diffraction planes of interest makes an angle less than 90 degrees with the surface normal. Diffraction is symmetric, regardless of whether the crystals are symmetrically or asymmetrically cut, enabling operation of the monochromator with a fixed plane of diffraction. As a result of the inclination of the crystal surface, an incident beam has a footprint area which is elongated both vertically and horizontally when compared to that of the conventional monochromator, reducing the heat flux of the incident beam and enabling more efficient surface cooling. Because after inclination of the crystal only a fraction of thermal distortion lies in the diffraction plane, slope errors and the resultant misorientation of the diffracted beam are reduced. 11 figures.

    We have measured force curves as a function of the lateral position on top of human platelets with the atomic force microscope. These force curves show the indentation of the cell as the tip loads the sample. By analyzing these force curves we were able to determine the elastic modulus of the platelet with a lateral resolution of approximately 100 nm. The elastic moduli were in a range of 1-50 kPa measured in the frequency range of 1-50 Hz. Loading forces could be controlled with a resolution of 80 pN and indentations of the platelet could be determined with a resolution of 20 nm.

    1985-12-09

    The mechanisms involved in the leaching of inorganic components from oil shale mined at the Rundle deposit, Queensland, Australia, and retorted by the Lurgi-Ruhrgas process were examined. The phenomena of most significance were found to be solute dissolution, cation exchange, solution speciation and hydrodynamic and unsaturated flow effects. To check on the completeness of this characterization, a model was developed which describes the generation and transport of the major components (Ca, Mg, Na, K, Cl and SO/sub 4/) in the leachate as it infiltrates a column of dry retorted shale. Model predictions compare well with experimental results. It is concluded that the dominant mechanisms which control the rate of leaching have been recognized. 8 references, 11 figures.

    1985-01-01

    Lotka's equations summarizing population dynamics can be approximated by functional models of the survivorship and reproductive curves, incorporating three stages of survival and reproduction, respectively. An abbreviated form uses a single reproductive parameter and two survival values. Survivorship and reproductive curves were fitted to data on northern fur seals (Callorhinus ursinus), domestic and feral sheep, white-tailed deer (Odocoileus virginianus), grizzly bears (Ursus arctos), African buffalo (Syncerus caffer), free-ranging horses, and fin whales (Balaenoptera physalus). Data for 10 species suggest a useful relationship between senescence parameters. A bias due to senescence may lead to serious underestimation of survival rates. Observed annual rates of increase of 18-20% for feral horses, 16% for southern fur seals (Arctocephalus gazella), and 60% for white-tailed deer are compatible with observed population parameters. 43 references, 11 figures, 3 tables.

    The objective is to provide technical assistance to METC's effort to develop a leading program in the evaluation of hydrate samples in porous media at reservoir conditions. An existing computer program has been modified to calculate enthalpies of dissociation, equilibrium pressures, and earth temperature-depth profiles for hydrate formation as a function of gas composition. In this report results of the depth-temperature studies are presented. The effect of gas composition, geothermal gradient, permafrost thickness and pressure gradient on the thickness of a hydrate stability zone in permafrost regions is covered. The effect of ocean bottom temperature, gas composition and ocean depth on a hydrate stability zone beneath the ocean is shown. These variables are considered to be among the more important in determining the potential that a particular region has for containing hydrates and they need to be measured in any geological investigation of a region. 24 references, 11 figures, 1 table.

    Measurements of neutron spectra produced by the Los Alamos National Laboratory (LANL) Little Boy replica assembly (Comet) were made with a combined multisphere and liquid scintillator system, that has been widely used at the Lawrence Livermore National Laboratory. The combined system was used for measurements at the side (90/sup 0/) and nose (0/sup 0/) of the assembly; additional measurements were made at 45/sup 0/ using only the liquid scintillator. Data were obtained at two meters from the center of the reactive region of the assembly, with good agreement between the multisphere and scintillator results. Comparison with liquid scintillator measurements performed by experimenters from the Canadian Defence Research Establishment, Ottawa (DREO) and calculations from LANL depended on the specific angle, obtaining the best agreement at 90/sup 0/. 32 references, 11 figures, 4 tables.

The eastern SR/PP are similar to other fold-and-thrust belts underlain by evaporites in that (1) it is part of a zone of overthrusting that extends considerably farther over the Himalayan foreland than adjacent areas not underlain by evaporites, (2) the overall thrust wedge has a narrow cross-sectional taper, (3) structures verge toward the hinterland as well as toward the foreland, and (4) fold trends are long and continuous, consisting of tight salt-cored anticlines separated by broad synclines. 11 figures, 1 table.

    A bus switching apparatus and method for multiple processor computer systems comprises a plurality of bus switches interconnected by branch buses. Each processor or other module of the system is connected to a spigot of a bus switch. Each bus switch also serves as part of a backplane of a modular crate hardware package. A processor initiates communication with another processor by identifying that other processor. The bus switch to which the initiating processor is connected identifies and secures, if possible, a path to that other processor, either directly or via one or more other bus switches which operate similarly. If a particular desired path through a given bus switch is not available to be used, an alternate path is considered, identified and secured. 11 figures.

    A metal to ceramic sealed joint which can withstand wide variations in temperature and maintain a good seal is provided for use in a device adapted to withstand thermal cycling from about 20 to about 1000 degrees C. The sealed joint includes a metal member, a ceramic member having an end portion, and an active metal braze forming a joint to seal the metal member to the ceramic member. The joint is positioned remote from the end portion of the ceramic member to avoid stresses at the ends or edges of the ceramic member. The sealed joint is particularly suited for use to form sealed metal to ceramic joints in a thermoelectric generator such as a sodium heat engine where a solid ceramic electrolyte is joined to metal parts in the system. 11 figures.

    Direct fluid injection mass spectrometry utilizes supercritical fluids for solvation and transfer of materials to a mass spectrometer chemical ionization (CI) source. Available data suggest that any material soluble in a supercritical fluid is transferred efficiently to the ionization region. Mass spectra are presented for mycotoxins of the trichothecene group obtained by use of supercritical carbon dioxide with isobutane as the CI reagent gas. Direct fluid injection MS/MS is also illustrated for major ions in the isobutane chemical ionization of T-2 toxin. The effect of pressure and temperature upon solubility in supercritical fluids is described and illustrated for diacetoxycirpenol. A potential method is also demonstrated for on-line fraction during MS analysis using pressure to control supercritical fluid solubility. Mass spectra are also presented for polar compounds, using supercritical ammonia, and the extension to complex mixtures is described. The fundamental basis and experimental requirements of the direct fluid injection process are discussed. 34 references, 11 figures, 1 table.

    The overall objective of this investigation is to provide a critical evaluation of the current information concerning coal-gasification wastewaters and to establish experimentally the extent of separation of phenolics and polynuclear aromatic hydrocarbons (from single and multi-solute synthetic systems) by low-and high-pressure composite membranes. The compounds selected for experimental investigation were: phenol, O-cresol, 2,3-dimethylphenol, catechol, resorcinol, 2-naphthol, naphthalene, and indole. The development of membrane separation processes is gaining considerable importance because of the feasibility of simultaneous removal of organics and inorganic dissolved solids. Cellulose-acetate membranes developed for desalination processes show no rejection of phenolics; however, recently developed thin-film, noncellulosic composite membranes (even at low-pressure operation) may be useful in gasification wastewater reuse schemes. 24 references, 11 figures, 5 tables.

    Our studies are concerned with the frequency tuning that is provided by the electrical resonance of tuberous electroreceptors. Frequency selectivity had previously been measured in the electroreceptor's afferent fibers, and resonant conductances in the electroreceptor cell membrane had been implicated in producing the selectivity. With transdermal application of sinusoidal current, we measured the frequency dependence of the impedance of small areas of the electroreceptor/skin structure of the weakly electric fish Sternopygus and Eigenmannia, and used our data to make a quantitative linear model of the structure. The qualitative form of the model was proposed by Bennett (1). The quantitative model allows us to estimate the frequency selectivity of the voltage across the innervated membrane of the electroreceptor cells. The frequency selectivity of electroreceptor cell voltage derived from our data are as sharp as the neural selectivity at frequencies close to the most sensitive frequency. Many of our measurements supported the linear system model. However, spontaneous electroreceptor voltage oscillations were detected in some of our specimens, suggesting that the electroreceptors can operate in a regime of active nonlinearity. A simple explanation for the observed oscillations is that they arise when damping in the electroreceptor cell's resonant membrane is negative for a limited span of membrane voltage surrounding the resting voltage. The response of oscillating units to sinusoidal current was compatible with this explanation. We report experimental observations bearing on the consequences of active nonlinearity for the frequency tuning of a resonant system.
