Abstract

In this modern era, gastrointestinal disorders are the universal problem. Peptic ulcer is one of the major diseases affecting the human population. It develops due to the imbalance between aggressive factors like acid, pepsin, H. pylori and bile salts and defensive factors like mucous, bicarbonate, blood flow, epithelial cell restoration and prostaglandins. The anti-ulcer activity of Ethanol extract of leaves of Lactuca sativa (EELS) was estimated using the experimental models of acute gastric lesions induced by ethanol, pylorus ligation and cold restraint stress in Wistar albino rats. Animals pre-treated with doses of 250 mg/kg, 500 mg/kg of EELS were statistically analyzed and compared to the standard and control group with the parameters like volume of gastric secretion, total acidity and ulcer index. The results suggested that EELS significantly decreased volume of gastric acid secretion, total acidity and ulcer index in comparison with standard drug Omeprazole. EELS shown significant reduction in lesion index, total affected area and percentage of lesion in comparison with control group in Ethanol induced ulcer in experimental models. The gastric mucosal protective effect of EELS is brought by inhibiting the gastric secretion, which shows it may act like a proton pump inhibitor. Thus the present study indicates that EELS has anti-ulcerogenic potency in Ethanol induced, pylorus ligation and cold restraint stress induced ulcers in rats.
