Trinitrobenzensulfonic acid (TNBS) is commonly used to induce an experimental inflammatory bowel disease (IBD) model. Oxidative stress and inflammation have been proposed as mechanisms underlying the pathophysiology of IBD. Aronia melanocarpa fruit juice (AMFJ) is extremely rich in polyphenolic substances, mainly proanthocyanidins, flavonoids and phenolic acids. The aim of this study was to evaluate the effect of AMFJ in a rat TNBSinduced colitis model and to compare the effect of the juice with that of sulfasalazine. Colitis was induced by TNBS in male Wistar rats. After the induction of colitis, AMFJ at three doses (2.5, 5 and 10 ml/kg) and sulfasalazine (400 mg/kg) were administered orally till the 14th experimental day. Severity of colitis was assessed by macroscopic and histopathological criteria. Oxidative stress was evaluated by the concentration of thiobarbituric acid reactive substances (TBARS). TNBS caused severe colonic damage. AMFJ dose-dependently ameliorated TNBS-induced colitis. It improved the macroscopic and microscopic signs of colitis, and prevented the increase of colonic TBARS concentrations. Regarding different indices, the effect of AMFJ was comparable or even higher than that of sulfasalazine. In conclusion, the ameliorative effects of AMFJ in the experimental TNBSinduced colitis might be the result of its potent antioxidant and antiinflammatory properties.
