Protective effect of royal jelly in 2,4,6 trinitrobenzene sulfonic acid-induced colitis in rats
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-co...
متن کاملDown-regulation of hepatic cytochrome P450 enzymes in rats with trinitrobenzene sulfonic acid-induced colitis.
Hepatic cytochrome P450 (P450) enzymes are down-regulated during inflammation. In this study, an animal model of inflammatory bowel disease was subjected to characterization of hepatic P450 expression under inflammatory conditions. Rats were treated intracolonically with 100 mg/kg trinitrobenzene sulfonic acid (TNBS) dissolved in 30% ethanol, and homogenates of colonic mucosa and hepatic micros...
متن کاملGlutamine prevents fibrosis development in rats with colitis induced by 2,4,6-trinitrobenzene sulfonic acid.
We investigated the effects of glutamine on the development of colonic fibrosis and on the expression of the major fibrogenic factors in a rat model of experimental colitis. Colitis was induced in one-half of the male Wistar rats by intracolonic administration of 30 mg of 2,4,6-trinitrobenzene sulfonic acid (TNBS). L-glutamine (25 mg/kg) was administered rectally to one-half of the controls and...
متن کاملAlpha-lipoic acid attenuates trinitrobenzene sulfonic acid-induced ulcerative colitis in mice.
Ulcerative colitis (UC), characterized by inflammation, oxidative stress, and increased intestinal epithelial cell apoptosis, is an immunologically mediated chronic intestinal disorder. The present study was aimed at investigating the protective effects of alpha-lipoic acid (ALA) against trinitrobenzene sulfonic acid (TNBS)-induced UC and the underlying mechanism. ALA of 80 mg/kg bw/day was adm...
متن کاملDual Role of Endogenous Serotonin in 2,4,6-Trinitrobenzene Sulfonic Acid-Induced Colitis
BACKGROUND AND AIMS Changes in gut serotonin (5-HT) content have been described in Inflammatory Bowel Disease (IBD) and in different experimental models of colitis: the critical role of this monoamine in the pathogenesis of chronic gastrointestinal inflammation is gradually emerging. Aim of the present study was to evaluate the contribution of endogenous 5-HT through the activation of its speci...
