[Effect of a couple of stimulants on the gastric motility (author's transl)].

The effects of the stimulants such as antral distention, administration of gastrin and insulin on the gastric motility were investigated in the dogs with innervated antral pouches. The results were as follows: 1. The gastric motility was markedly increased by these stimulants and characteristic motility patterns were recognized in each stimulants. 2. Antral distention stimulated strongly the contraction pressure but not in the frequency of the gastric contractions. 3. Gastrin produced regular and higher frequency contractions and the decrease in contraction pressure of the stomach. 4. Insulin stimulated both of the contraction pressure and the frequency of the gastric contractions. 5. The tests of compound stimulation by each two of these stimuli demonstrated that gastrin constantly produced an increase in frequency and a decrease in contraction pressure and that antral distention always increased the contraction pressure of the stomach.
