AIM: To compare Helicobacter pyloriinfection and gastric mucosal histological features of gastric ulcer patients with chronic gastritis patients in different age groups and from different biopsy ***: The biopsy specimens were taken from the antrum, corpus and upper angulus of gastric ulcer and chronic gastritis patients. Giemsa staining, improved Toluidine-blue staining and H pylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylineosin staining was used for the histological diagnosis of activity of H pylori infection, mucosal inflammation,glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney ***: Total rate of H pylori infection, mucosal inflammation, activity of H pylori infection, glandular atrophy and intestinal metaplasia in 3 839 gastric ulcer patients (78.5%, 97.4%, 82.1%, 61.1% and 64.2%,respectively) were significantly higher than those in 4 102chronic gastritis patients (55.0%, 90.3%, 56.2%, 36.8%,and 37.0%, respectively, P＜0.05). The rate of H pylori colonization of chronic gastritis in ＜30 years, 31-40 years,41-50 years, 51-60 years, 61-70 years and ＞70 years age groups in antrum was 33.3%, 41.7%, 53.6%, 57.3%,50.7%, 43.5%, respectively; in corpus, it was 32.6%,41.9%, 53.8%, 60.2%, 58.0%, 54.8%, respectively; in angulus, it was 32.4%, 42.1%, 51.6%, 54.5%, 49.7%,43.5%, respectively. The rate of Hpyloricolonization of gastric ulcer in ＜30 years, 31-40 years, 41-50 years,51-60 years, 61-70 years and ＞70 years age groups in antrum was 60.5%, 79.9%, 80.9%, 66.8%, 59.6%, 45.6%,respectively; in corpus, it was 59.7%, 79.6%, 83.6%,80.1%, 70.6%, 59.1%, respectively; in angulus, it was61.3%, 77.8%, 75.3%, 68.8%, 59.7%, 45.8%,respectively. The rate of H pylori colonization at antrum was similar to corpus and angulus in patients, below50 years, with chronic gastritis and in patients, below40 years, with gastric ulcer.
