A study of histopathological gastritis of Helicobacter pylori infected peptic ulcer -difference of gastric ulcer and duodenal ulcer-

Abstract

It is well known that there is a chronic active gastritis (CAG) in Helicobacter pylori (H. pylori) infected stomach. A characteristics of CAG between in H. pylori positive gastric ulcer and duodenal ulcer were studied. We found many differences as follows :
1) CAG was stronger in corpus than in antrum in H. pylori positive gastric ulcer. It was remarkable in cases accompany by gastric mucosal atrophy.
2) In H. pylori positive duodenal ulcer, CAG was stronger in antrum than in corpus. There was no relation in atrophic change of gastric mucosa.
