METHODS： Acute gastric ulceration in rats was produced by various noxious chemicals including 80% ethanol, 0.2 mol/L NaOH, 25% NaCI and indomethacin. Anti-secretory studies were undertaken using pylorusligated Shay rat technique. Levels of gastric non-protein sulfhydryls （NP-SH） and wall mucus were estimated and gastric tissue was also examined histologically. Anise aqueous suspension was used in two doses （250 and 500 mg/kg body weight） in all experiments. RESULTS： Anise significantly inhibited gastric mu- cosal damage induced by necrotizing agents and indomethacin. The anti-ulcer effect was further confirmed histologically. In pylorus-ligated Shay rats, anise suspension significantly reduced the basal gastric acid secretion, acidity and completely inhibited the rumenal ulceration. On the other hand, the suspension significantly replenished ethanol-induced depleted levels of gastric mucosal NP-SH and gastric wall mucus concentration. CONCLUSION： Anise aqueous suspension possesses significant cytoprotective and anti-ulcer activities against experimentallynduced gastric lesions. The anti-ulcer effect of anise is possibly prostaglandin-mediated and/orthrough its anti-secretory and antioxidative properties.展开更多
