title: Effect of different caloric loads in human jejunum on meal-stimulated and nonstimulated biliopancreatic secretion.
abstract: The effects on biliopancreatic secretion of two caloric loads (1.3 and 3.3 kcal/min of Realmentyl: proteins 18%, lipids 27%, carbohydrates 55%), infused into the jejuna of 10 healthy men, were compared with those of a control solution. In one set of experiments (six subjects) when biliopancreatic secretion was not stimulated before infusion, the rate 1.3 kcal/min resulted in mild stimulation whereas the rate 3.3 kcal/min brought about an inhibition of biliopancreatic secretion. In another set of experiments (six subjects) when biliopancreatic secretion was stimulated by ingestion of an homogenized meal (400 mL, 490 kcal) 1 h before the start of infusion, both loads resulted in strong inhibition of pancreatic secretions, the effect being more pronounced with the high caloric load.
