title: [Ultracytochemical study of oxidoreductases in the parietal cells of the gastric mucosa in gastric cancer].
abstract: Ultracytochemistry was used to study and compare cytochromooxidase, succinate dehydrogenase and NADH-dehydrogenase activity in gastric mucosa parietal cells in health and in gastric carcinoma associated with decreased acidity of gastric juice. The study demonstrated the reduced activity of the enzymes listed in the mucosal parietal cells in gastric carcinoma. This finding is interpreted as a consequence of disturbed energy supply of hydrochloric acid secretion in gastric carcinoma.
