[The characteristics of the morphological changes in the gastric mucosa in duodenal peptic ulcer, ulcer recurrence after vagotomy and in the Zollinger-Ellison syndrome].

Results of morphometry and count of certain kinds of endocrinocytes of gastric mucosa are analyzed. Pronounced proliferative alterations of the gastric mucosa were found with clear signs of the increased function of the structures responsible for acid gastric secretion. In part of the patients with ulcer disease of the duodenum there are considerable changes in the amount of certain kinds of endocrinocytes of the antral portion of the stomach, which form accumulations in the form of different fields and even focal zones. Such alterations in the gastric mucosa have correlative relationships with the level of acid gastric secretion.
