Many studies dealing with trinitrobenzene sulfonic acid (TNBS) colitis in rats have been carried out referring only to the colon. In humans, ulcerative colitis (UC) can extend a variable distance into the terminal ileum in a phenomenon known as backwash ileitis (BWI). The aim of this study was therefore to examine the effect of TNBS-induced colitis on different aspects of the rat ileum and jeju...

Hemp (Cannabis sativa L.) seeds have recently been attracting attention as a new high-value-added food material owing to their excellent nutritional properties, and research on the development of functional materials using hemp is actively progressing. This study aimed evaluate antioxidant properties seed protein hydrolysates. Protein hydrolysates were prepared from defatted powder (HS) by enzy...

objective(s):in the present study, we evaluated immunological and immunomodulatory properties of royal jelly (rj) in 2,4,6 trinitrobenzene sulfonic acid (tnbs)-induced colitis in rats. materials and methods: eighteen adult female wistar albino rats were divided into three groups of six animals each: a control group that received only saline solution, a tnbs-induced colitis group, and a tnbs-col...

trinitrobenzene sulfonic acid (tnbs)-induced colitis is one of the most common methods for studying inflammatory bowel disease in animal models. several factors may, however, affect its reproducibility, rate of animal mortality, and macroscopic and histopathological outcomes. our aim was to validate the main contributing factors to this method and compare the effects of different reference drug...

Thymocyte apoptosis in adult Xenopus laevis is demonstrated on agarose gels and is quantified by propidium iodide incorporation using flow cytometry. Basal apoptotic levels are increased after in vitro exposure to a glucocorticoid, dexamethasone (DEX), and to the lectin, phytohemagglutinin (PHA). To determine the role that newly introduced antigenic determinants may play in this regard, a reper...

The secretory enzyme extracellular-superoxide dismutase (EC-SOD) has affinity for heparin and some other sulfated glycosaminoglycans and is in vivo bound to heparan sulfate proteoglycan. Nonenzymic glycation of EC-SOD, both in vivo and in vitro, is associated with a reduction in heparin affinity, whereas the enzymic activity is not affected. The glycation sites in EC-SOD are further studied in ...

AIM To evaluate the anti-inflammatory intestinal effect of the ethanolic extract (EtOHE) and hexane phase (HexP) obtained from the leaves of Combretum duarteanum (Cd). METHODS Inflammatory bowel disease was induced using trinitrobenzenesulfonic acid in acute and relapsed ulcerative colitis in rat models. Damage scores, and biochemical, histological and immunohistochemical parameters were eval...

In this study, we show that a single intranasal dose of a plasmid encoding active transforming growth factor b 1 (pCMV-TGFb 1) prevents the development of T helper cell type 1 (Th1)mediated experimental colitis induced by the haptenating reagent, 2,4,6-trinitrobenzene sulfonic acid (TNBS). In addition, such plasmid administration abrogates TNBS colitis after it has been established, whereas, in...
