ABSTRACT
The present study was carried out to see the effect of two zinc salts i.e zinc sulphate and zinc chloride on gastric ulcers induced by stress, pylorus ligation and aspirin in albino rats. The rats were divided into two main groups (zinc sulphate 30, 60, 90 mg/kg i.p and zinc chloride 10 and 20mg/kg i.p). They were further sub-divided into three sub-groups dependant on ulcer model i.e stress, pylorus ligation and aspirin induced ulcers. It was found that zinc sulphate and zinc chloride had a dose dependant reduction in ulcer index in all three models of gastric ulceration. Also, both the salts had anti acid secretory effect, raised pH of gastric secretion and reduced total acidity significantly. Thus zinc salts prevent gastric ulceration. Probably this effect is mediated by anti acid secretory action.
