[Effect of bilateral and unilateral vagal stimulation of gastric acid production in the rat].

In experiments on rats the anterior or/and the posterior gastric vagus nerve were electrically stimulated. The extent and site of acid-producing gastric areas were demonstrated by help of Congo red. Unilateral stimulation resulted in enhanced acid secretion in a smaller area of gastric mucosa. The acid-secreting areas showed no different distribution at stimulation of the anterior or posterior vagus nerve.
