title: [Anti-gastric ulcer activity of zinc sulfadiazine in rats].
abstract: Zinc sulfadiazine (ZnSD) 50, 100, 200 mg/kg ig inhibited the formation of gastric ulcer induced by indomethacin, stress and pyloric ligation in rats respectively and showed dose-dependently. ZnSD 200 mg/kg ig accelerated the healing of gastric ulcer induced by acetic acid. ZnSD 25 mg/kg ig was effective in preventing ethanol-induced damage of rat gastric mucosa. The amount of gastric mucus glycoprotein in gastric tissues was increased by ZnSD. In general, ZnSD did not influence the volume of gastric juice and pepsin output, but ZnSD 200 mg/kg ig decreased gastric acidity. In vitro, ZnSD also influenced the neutralization of acid. It is suggested that antiulcer action of ZnSD may be related to its preservation of the gastric mucosal barrier and neutralization of acid.
