[The pharmacological blockade of the cardiac and gastric enteric ganglia by a new parasympatholytic].

The blocking effects of a newly synthetized compound N-decyltropine bromide (IEM-1556), on pentagastrin-, carbachol- and histamine-induced gastric secretion in chronic dogs, on stress-induced changes in gastric mucosa in rats, on vagus-induced effect in heart and on arterial blood pressure in rats were studied. The effects were compared with those produced by hexamethonium, a conventional ganglionic blocking agent. IEM-1556 inhibited gastric secretion and acid output for a much longer time than hexamethonium did.

[Experimental substantiation of extragastric vagotomy in the surgical treatment of gastric and duodenal ulcer].

The small intestine vagotomy influence on gastric secretion function, stimulated by pentagastrin and carbachol, was investigated while chronic experiment on dogs with gastric fundal and duodenal fistulas. The comparative analysis of influence of extragastric selective proximal, selective distal, selective and truncal vagotomy on gastric secretion in various terms after operative intervention was also conducted. In 6 months after conduction of various kinds of vagotomy the reduction of hydrochloric acid secretion, stimulated by pentagastrin, was noted.
