[Effect of partial sympathectomy of the stomach and small intestine on the neurogenic inhibition of gastric secretion].

In acute experiments on dogs, inhibition of the stomach secretion produced by the stimulation of major splanchnic nerves was studied. The extensive postganglionic stomach desympathization failed to eliminate this inhibition whereas the partial postganglionic small intestine denervation decreased it. In neurogenic inhibition of the stomach secretion, sympathetic nerves, apart from their direct effect on the stomach, seem to inhibit the stomach secretion through the inhibitory mechanisms of the small intestine.
