title: [Effect of blockaders of biogenic amine receptors on experimental ulcer development].
abstract: The effects of serotonin antagonist peritol, cholinolytic atropine, H2-receptor blocker cimetidine and dopaminergic receptor blocker metoclopramide on stress- and exogenous serotonin-induced gastric ulcerogenesis in rats were studied. Peritol was shown to inhibit significantly serotonin- an stress-induced hemorrhagic effect. Similar but less pronounced inhibit produced by metoclopramide and cimetidine. Atropine decreased gastric hemorrhages induced by serotonin but failed to affect stress-induced hemorrhagic lesions. All antagonists tested decreased stress-induced erosions. Erosive lesions stimulated by exogenous serotonin were significantly decreased by atropine only. Metoclopramide known for its cholinomimetic action increased serotonin-induced erosions. It was concluded that serotonin plays an essential role in the pathogenesis of gastric lesions, and its effects suggest the involvement of acetylcholine, histamine and dopamine.
