Objective: The ethanolic extract of Vitis vinifera leaves (VVE) (500 mg/kg body weight), ranitidine (50 mg/kg body weight) and both of them were tested for their gastroprotective and curative effects against the incidence of peptic ulcer.

Methods: The antiulcer effects of VVE were investigated using a combination of indomethacin and cold-stress for 2h. To ascertain the mechanism of action of VVE, its protective and curative effects were studied on gastric volume, gastric juice acidity, ulcer index and malondialdehyde (MDA), glutathione (GSH), catalase (CAT), glutathione–S-transferase (GST), superoxide dismutase (SOD), nitric oxide (NO) activities of both stomach and duodenum of rats. Moreover, histopathological effects on stomach and duodenum were determined.

Results: The antioxidant activity of VVE was demonstrated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) test. VVE was found to reduce the ulcer index, gastric volume and the level of gastric juice acidity. Also, VVE showed gastroprotective and curative activities mainly through improvement of antioxidant status and decreasing lipid peroxidation accompanied with amelioration of both stomach and duodenum architectures.

Conclusion: The prophylactic and curative effects of VVE proved to be effective in preventing gastric and duodenal ulceration which may be probably due to its antioxidant and anti-acid secretory effects.

Keywords: Severe gastric ulcer, Rats, Indomethacin, Cold stress, Oxidative stress
