Mycophenolate mofetil (MMF) is an alternative immunosuppressive agent that has been reported to be effective and well tolerated for the treatment of refractory inflammatory bowel disease (IBD). The aim of this study was to investigate the therapeutic effect of MMF on intestinal injury and tissue inflammation, which were caused by Crohn's disease (CD). Here, trinitrobenzene sulfonic acid-relapsi...
Andrographolide is a traditional herb medicine, widely used in Asia for conditions involving inflammation. The andrographlide-lipoic acid conjugate, AL-1, has been found being able to alleviate inflammation in our previous reports. Although the anti-inflammatory activity of AL-1 contributes to its cytoprotective effects, whether AL-1 can improve inflammatory bowel disease (IBD) and the underlyi...
To study the acute and long-term effects of local gut inflammation on the sensitivity of the spinal sensory neurons, the expressions of vanilloid receptor 1 (VR1) and calcitonin gene-related peptide (CGRP) in the colon-innervated primary sensory neurons in dorsal root ganglia (DRG) were examined in rats with trinitrobenzenesulfonic acid (TNBS)-induced experimental colitis. The neurons projectin...
We investigated the actions of probiotics, Streptococcus faecalis 129 BIO 3B (SF3B), in a trinitrobenzenesulfonic acid- (TNBS-) induced colitis model in rats. After TNBS was administered into the colons of rats for induction of colitis, the rats were divided into two groups: one group was given a control diet and the other group was given a diet containing SF3B for 14 days. There were no appare...
Irritable bowel syndrome is characterized by colorectal hypersensitivity and contributed to by sensitized mechanosensitive primary afferents and recruitment of mechanoinsensitive (silent) afferents. Neurotrophic factors are well known to orchestrate dynamic changes in the properties of sensory neurons. Although pain modulation by proteins in the glial cell line-derived neurotrophic factor (GDNF...
Inflammatory bowel disease (IBD) is chronic inflammatory and relapsing disease of the gut. It has been known that activation of nuclear factor-kappaB (NF-kappaB) and production of proinflammatory cytokines play important roles in the pathogenesis of IBD. In this study, the effect of vanillin (4-hydroxy-3-methoxybenzaldehyde), a potent nuclear factor-kappaB (NF-kappaB) inhibitor, was evaluated i...
C3H mice were immunized with MH134 tumors modified with two different chemicals, DEPC and TNBS, and the tumor-neutralizing activities of the spleen cells were examined after separating the cells by a Nylon-wool column, plastic dish, or treatment with specific antibodies (anti-mouse IgG and anti-mouse theta sera). The effector cells induced in mice by immunization with TNBS-treated tumors were T...
To investigate the potential involvement of T helper (Th)2-type responses in murine models of intestinal inflammation, we used trinitrobenzene sulfonic acid (TNBS)-hapten to induce inflammatory bowel disease in situations where Th1-type responses with interferon (IFN)-gamma synthesis are either diminished or do not occur. Intracolonic administration of TNBS to either normal (IFN-gamma+/+) or Th...
To understand the interactions between substance P and gut inflammation, changes in substance P levels were evaluated in a chronic model of ileitis in response to three anti-inflammatory agents with distinct mechanisms of action. The agents were the prostaglandin E(1) analogue misoprostol (30 mug/kg, s.c., b.i.d.), the nitric oxide synthase inhibitor N(G)-nitro-L-arginine methyl ester (L-NAME, ...
Mesenteric fat is known to undergo inflammatory changes after 2,4,6,-trinitrobenzensulphonic acid (TNBS)-induced colitis. Neurotensin (NT) and neurotensin receptor 1 (NTR1) have been shown to play a major role in the pathogenesis of intestinal inflammation. This led us to explore whether NT and NTR1 are expressed in the mesenteric fat depots during TNBS-induced colitis and whether NT participat...
