Helicobacter pylori Infection in Duodenal Ulcer ; In Relation to the Gastric Mucosa

Abstract

A relation among Helicobacter pylori (H. pylori) infection, histological chronic active gastritis with biopsy specimen and endoscopic gastric mucosa in duodenal ulcer were studied.
1) Many cases were infected with H. pylori. An infection rate occupied 88.9%.
2) A frequency of histological chronic active gastritis in H. pylori infected cases in the greater curvature of lower antrum showed over 90%, which was same in the greater curvature and lesser cuevature of body.
3) We got no relation between infection rate and gastric mucosa in duodenal ulcer. It was different from gastric ulcer and normal control group. In these groups, a positive rate rose with an increase of atrophic grade, and decreased it in severe atrophic group.
