[Changes in the intermediary glands of the gastric mucosa in peptic ulcer of different localization in morphometric interpretation].

Histologically and morphometrically (by the method of V.A. Samsonov). 80 stomachs resected for peptic ulcers were studied. Intermediary glands without atrophy were found in 16.3% of cases, atrophic changes in 51.2% of cases; in 32.5% of cases they disappeared completely and were substituted mainly by fields of intestinal metaplasia they disappeared completely and were substituted mainly by fields of intestinal metaplasia and pseudopyloric glands. In the atrophic process the number of cells increased in the gastric fossas and decreased in the glands; the gland-fossa epithelial cell index and the ratio of chief and parietal cells decreased. In the epithelial formula of intermediary gland the percentage of secondary and undifferentiated cells increased and that of parietal and particularly chief cells decreased. When the ulcers were localized in the stomach the glands were involved more frequently and extensively than in duodenal ulcers.
