title: [Reverse diffusion of hydrogen ions and its correlation with acid secretion and proliferative activity of gastric mucosal epithelium in patients with variants of chronic gastritis and peptic ulcer].
abstract: Eighty-one patients with chronic gastritis and 124 patients with peptic ulcer were examined. It was discovered that in chronic gastritis, the concomitant gastritis included, in patients with peptic ulcer, the degree of enhancement of reverse diffusion of hydrogen ions depended on the intensity of atrophy of the fundal and antral mucosa as well as on the extent of gastric lesions. The duodenogastral reflux promoted the increase of reverse diffusion of hydrogen ions. In mediogastral ulcer site, reverse diffusion of hydrogen ions was, at the height of exacerbation, enhanced to a greater degree than in the stage of ulcer healing. In atrophic variants of chronic gastritis and in peptic ulcer patients with an ulcer sited in the stomach, a close positive correlation was noted between reverse diffusion of hydrogen ions and proliferative activity of the gastric mucosa epithelium and a negative correlation between the diffusion and hydrochloric acid secretion. In patients with peptic ulcer of the duodenum without gastritis or the duodenogastral reflux, the characteristics of reverse diffusion of hydrogen ions did not differ from those seen in normal subjects.
