Chronic experiments were staged on 9 dogs with multipolar electrodes implanted into the hypothalamus. The amount of saliva secreted and the rate of its secretion in hypothalamic stimulation depends on the frequency and the stimulating current. The maximum amount of saliva secretion is observed at 40 pulses per sec (pulse duratio— 0.2 millisec, 0.7–0.8 and(More)
The substance P was shown to be able to increase the level of histamine-induced stomach secretion and the debit of free hydrochloric acid in dogs. This peptide increases the volume velocity of the choleresis and the content of bile acids and protein in the bile. The substance P alters the range of the bile acids as well.
Chronic experiments in dogs showed that, after i.v. injection of oxytocin, the latency of activation of gastrointestinal motility by the stimulation of median hypothalamic structures was increased and inhibitory effects of posterior hypothalamic structures on the contractile activity of the digestive tract were intensified. The data obtained suggests that(More)
Chronic experiments on hypophysectomized dogs with gastric and small intestinal fistulas as well as with hypothalamus-implanted electrodes have shown that blockade of alfa-adrenoreceptors by phentolamine increases the number of the excitatory motility responses while stimulating hypothalamic structures during rest of the gastrointestinal tract and decreases(More)
