[Structure of the gastric mucosa following experimental antrectomy].

The important role of the antral part of the stomach in sustaining the gastric mucosa tissue homeostasis has been shown in chronic experiment in dogs. In 5-13 months after antrectomy the thickness of the gastric mucosa diminishes by 21% at an average, the height of the fundal glands-by 29%, the amount of the parietal cells-by 54%, the amount of basic cells-by 34%. Hypoplastic lesions of the gastric mucous membrane develop and complete within the first months after antrectomy. After the 5th month the degree of hypoplasia fails to markedly increase, i. e. the shifts found are not of constantly progressing character.
