The energy systems of gastric tissues, their neural, hormonal and pharmacological regulations in order to gastric H+ secretion and ulcerogenesis. (A review of animal experiments and clinical biochemical studies).

Abstract
In studies conducted over the last 10 years, the ATP, ADP, AMP concentrations, the adenylate pool (ATP + ADP + AMP), the "energy charge" and the cAMP levels were determined:(1) in gastric tissues of pylorus-ligated rats, (2) in gastric and duodenal mucosa and muscular layer (musculature) of human subjects qualified as "hypacid", "normacid" and "hyperacid" on the basis of basal (BAO) and maximal acid output (MAO), (3) in ulcer-bearing and non-ulcerous antral, duodenal and jejunal mucosa and muscular layer of patients with peptic ulcer, including chronic (essential) antral, duodenal ulcer and jejunal ulcer following gastric resection of Billroth II-type. Close analysis of the results centres on: (1) the biochemical background of gastric hypersecretion and of ulcerogenesis in pylorus-ligated rats;(2) the extra- and intracellular feedback system operating between the gastric membrane ATPase and adenylate cyclase systems, under normal and abnormal conditions of the effector organ; (3) questions related to the regulatory mechanisms of functional activity of the effector organ under drug effect; (4) the energy structure of the mucosa and muscular layer of corpus ventriculi, antrum and duodenum in patients considered "hypacid", "normacid" and "hyperacid" on the grounds of the BAO and MAO values; (5) the interrelationships between human gastric H+--K+-dependent ATPase system of gastric corpus mucosa; (6) pharmacological regulation of the ATP--ADcer-free mucosa and musculature of patients with antral, duodenal and jejunal ulcers.
