Zusammenfassung:Background. Change in apoptosis in gastric glands after eradication of Helicobacter pylori has never been reported. Aims. The purpose of this paper is to investigate the change in apoptosis in gastric glands after eradication of Heliobacter pylori. Patients and methods. We studied 23 Heliobacter pylori-positive patients with duodenal and gastric ulcers, who were monitored for 6–12 months after eradication, and eight controls. Biopsies were taken from the antrum and body. Apoptosis was evaluated immunohistochemically using anti-single stranded DNA antibody. Apoptotic index was calculated by counting immunostained cells in surface epithelial and glandular cells. Results. In the surface epithelium, Apoptotic indexes were significantly higher in patients than in controls. In the upper portion of fundic glands, apoptotic indexes were significantly higher in patients with gastric ulcers (14.2% (9.3, 17.8)) (median (1st quartile, 3rd quartile)) than in controls (8.0% (2.0, 9.0), p
