Abstract
There is a pressing need for research that will lead to the reveal of targets designed to analyse the possible pathways for the treatment of IBD. Because of the probable involvement of serotonin in inflammatory conditions of intestine and the important role of 5HT(4) receptors in GI function, the investigation of the role of 5HT(4) receptors in the pathogenesis of IBD will be interesting. The aim of this study was to investigate the effects of cisapride, a 5HT(4) receptor agonist, in trinitrobenzenesulfonic-acid-(TNBS) induced rat colitis. Two hours subsequent to induction of colitis using TNBS in rats, cisapride (2 mg/kg, intraperitoneally (i.p); 4 mg/kg, orally (p.o)) and dexamethasone (1 mg/kg, i.p; 2 mg/kg, p.o) were administrated for 6 days. Animals were thereafter euthanized; macroscopic, histological, and biochemical assessments and ELISA test were carried out on distal colon samples. Our data showed that dexamethasone treatment (i.p, p.o) significantly decreased macroscopic and microscopic damage and also biochemical markers, but there were no significant differences in aforementioned parameters between cisapride (i.p or p.o) and TNBS-treated rats. It can be deduced that because the severity of colitis produced by TNBS is massive (through various pathways), cisapride could not bring about more colitis damages through 5HT(4) receptors. Based on the present study further researches are required for investigating the exact roles of 5HT(4) receptors in the pathogenesis of ulcerative colitis.
