[The anti-ulcer action of zinc sulfate in models of acute and chronic ulcerogenesis in the rat duodenum]

Abstract

The 5-day pretreatment of rats with zinc sulfate (50 or 150 mg/kg/day per os) significantly reduce the rate, the number, and area of cystamine-induced duodenal lesions in rats. Pretreatment with zinc sulfate in a dose of 15 mg/kg/day over a 5-day period or single administration of zinc sulfate (50 mg/kg) did not markedly reduce the above-mentioned lesion parameters. The administration of zinc sulfate (50 or 150 mg/kg/day per os) during 7 days results in a dose-dependent, significant decrease in the area of chronic acetate-induced gastric and duodenal lesions in rats. The results of clinical and experimental study indicate that zinc-containing compounds can be successfully used both for prophylaxis and treatment of duodenal ulcer.
