BACKGROUND: This study investigates the protective effects of turmeric (Curcuma longa, CL) on acetic acid-induced colitis in rats.

METHOD: Inflammatory bowel disease (IBD) was induced in male Wistar rats by intra-rectal administration of 1 ml of 4 % acetic acid at 8 cm proximal to the anus for 30 s. Curcuma longa (CL) powder, (1, 10, or 100 mg/kg/day) was administered for either 3 days before or after IBD for 7 days. The body weight, macroscopic and microscopic analysis of the colon of CL-treated IBD rats and that of control rats (no IBD, no CL) were performed on 0 day, 2, 4 and 7th day. Myeloperoxidase (MPO), IL-23 and glutathione levels in control, untreated and treated rats were measured by ELISA.

RESULTS: CL significantly (P < 0.05) improved IBD-induced reduction in mean body weight and mean macroscopic ulcer score. Administration of CL also significantly (P < 0.01) reduced the mean microscopic ulcer score when compared to untreated IBD control. Intake of CL by rats resulted in a significant (P < 0.05) increase in the mean serum glutathione level compared to untreated control. CL reduced both MPO and IL-23 levels in the colonic mucosa of the rat.

CONCLUSION: CL improved body weight gain, mean macroscopic and microscopic ulcer scores in the colon of rats suffering from acetic acid-induced IBD. CL reduced both MPO and IL-23 in the mucosa of the colon. The increase in the mean serum glutathione level may help in the reduction of oxidative stress associated with IBD.
