[Selectivity of inhibition of pancreatic enzyme secretion after lipase administration into the duodenum].

Administration of lipase into the duodenum inhibits pilase secretion and, to a lesser extent, secretion of proteinases in dogs. The inhibitory effect is prevented by simultaneous administration of cotton oil and hydrolysine acidized up to pH-2. The lipolytic activity of duodenal chyme seems to play a major part in correction of pancreatic juice enzyme range in urgent adaptation of pancreatic secretion to a type of consumed food.
