The present study was carried out to evaluate antiulcer activity of hydroalcohol extract of Momordica dioica Roxb. fruit. Momordica dioica Roxb. fruit extract (100, 200 and 400 mg/kg body weight) was administered orally, twice daily for 5 days for prevention from ethanol, cold-restraint stress and pylorus ligation-induced ulcers. Estimation of H+-K+ ATPase activity and gastric wall mucous were performed in ethanol-induced ulcer model, antioxidant enzyme activities was carried out in cold-restraint stress-induced ulcer model, and various gastric secretion parameters like volume of gastric juice, acid output, and pH value were estimated in pylorus ligation-induced ulcer model. A significant reduction in lesion index was observed in ulcer-induced animals pre treated with extract at different doses when compared with ulcerated rats in all models. A significant decrease occurred in the level of H+-K+ ATPase, volume of gastric juice, and acid output. Gastric wall mucus and pH were increased significantly. These showed dose-dependent action of extract. LPO and antioxidant enzyme levels of SOD were decreased, but CAT enzyme showed significant increase. Thus the results indicate that the Momordica dioica extract possess antiulcerogenic effect, that attributable to augmentation of gastric defense mechanisms.
