Abstract

Background: Exposure of gastric mucosa to concentrated ethanol induces acute gastritis. Gastric mucosal lipid peroxidation plays a significant role in the pathogenesis of ethanol-induced gastric mucosal lesions. The aim of this study was to investigate the effect of sesame oil on acidified ethanol-induced gastric mucosal damage in rats. Methods: We performed gastric bilateral vagotomy in rats. A small incision on forestomach was made and stomach content was expelled. Normal artificial gastric acid (54 mM NaCl plus 100 mM HCl) or acidified ethanol (30% ethanol plus 150 mM HCl) was instilled into the stomach. Gastric lipid peroxidation, glutathione, and nitric oxide levels were measured 3 hours after acidified ethanol administration. Results: Acidified ethanol caused mucosal ulceration, luminal hemorrhage, lipid peroxidation, and a lower level of mucosal glutathione and nitric oxide production. Pretreatment of sesame oil, but not mineral oil, significantly decreased acidified ethanol-induced mucosal ulcer formation and luminal hemorrhage. Sesame oil reduced mucosal lipid peroxidation, as well as glutathione and nitric oxide production in acidified ethanol-treated stomachs. Furthermore, both sesame oil and mineral oil did not affect serum ethanol concentration in acidified ethanol-treated rats. Conclusion: Sesame oil attenuates acidified ethanol-induced gastric mucosal injury by reducing oxidative stress in rats.
