[Activity of various intracellular enzymes of the gastric mucosa in chronic gastritis and tumors].

Changes in levels of such redox enzymes of gastric mucosa as cytochrome oxidase, carboanhydrase and succinic dehydrogenase occurring in various forms of chronic gastritis were assessed with respect to morphological peculiarities and secretory function. A total of 102 cases (77--various forms of gastritis, 11--gastric neoplasms and 14--controls) were examined. Specific changes in atrophic antral and chronic histamine-resistant achlorhydric gastritis were identified.
