Abstract
Gastric mucosal ulceration was produced in rats following intraperitoneal injection of indomethacin (40 mg/kg). The incidence of ulcerations was progressively reduced as the bile flow was diverted progressively distal to the ampulla of Vater. It is suggested that bile reflux into the stomach may play a part in the pathogenesis of indomethacin-induced gastric ulceration in rats.
