[Effect of parenterally administered protein hydrolysates on the motor function of the stomach and small intestine]

Intravenous administration of proteinic hydrolysates (caseine and aminopeptide hydrolysates) to dogs for a duration of 2 hours debars on active period in the fasting periodic activity of the stomach, this being attended by the stimulation of gastric secretion with pH changing from alkaline or neutral to acid reaction. Introduction of the caseine and aminopeptide hydrolysate did not cancell out the active period of the duodenal motoricity, though the frequency of contractions was somewhat below that in controls.
