isolation of rat islets of langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of hanks' solution into the common bile duct. the identification of the islets was done by techniques including the use of a stereomicroscope against a black background. vital staining was done by an injection of neutral red solution through ...

Clostridium difficile toxin A is associated with enterocolitis in animals and humans. However, the mechanisms of its secretory and damaging effects are not totally understood. In this work, we examined the intestinal secretion of electrolytes and water caused by supernatants from macrophages stimulated with toxin A in rabbit ileal mucosa mounted in Ussing chambers. We also investigated the mech...

We report a case of a 58-year-old woman with a true non secretory multiple myeloma of the producer type relapsing after many lines of therapy including the novel anti-myeloma drugs, which eventually relapsed as extramedullary liver plasmacytomas manifesting as a fatal acute cholestatic hepatitis. Due to the aggressiveness of this disease, new therapeutic modalities are necessary.

M cells of intestinal epithelia overlying lymphoid follicles endocytose luminal macromolecules and microorganisms and deliver them to underlying lymphoid tissue. The effect of luminal secretory IgA antibodies on adherence and transepithelial transport of antigens and microorganisms by M cells is unknown. We have studied the interaction of monoclonal IgA antibodies directed against specific ente...

Abstract Objective Snails secrete different types of mucus that serve several functions, and are increasingly being exploited for medical cosmetic applications. In this study, we explored the protein pattern compared biological properties secreted from mantle collar foot two snail species, Lissachatina fulica Hemiplecta distincta . Result Protein profile showed a between species secretory parts...

Chantaleela recipe is indicated for relieving fever in Thai traditional folk medicine. In the present study, Chantaleela recipe was investigated for anti-inflammatory, analgesic, antipyretic and anti-ulcerogenic activities. In preliminary investigation Chantaleela recipe was found to exert an inhibitory activity on the acute phase of inflammation as seen in ethyl phenylpropiolate-induced ear ed...

The roles of IgG and secretory IgA in the protection of the respiratory tract (RT) against influenza infection remain unclear. Passive immunization with Ab doses resulting in serum IgG anti-influenza virus Ab titers far in excess of those observed in immune mice has compounded the problem. We compared the effects of i.v. anti-influenza virus IgG and i.v. anti-influenza virus polymeric IgA (pIgA...
