[The role of the proteins of the blood plasma in the homeostasis of its amylase and pepsinogen].

Hypervolemia and stimulation of diuresis in dogs was found to decrease the amylolytic activity of the blood plasma and pepsinogen concentration. The number of enzymes bound with blood plasma albumins decreases in hyper-fermentation. The changing connexion of the plasma albumins with the enzymes entails a renal (as well as extrarenal) extraction of the enzymes from the organism and maintenance of their relatively constant concentration and activity in the blood.
