[Secretion of amylase and lipase in bile].

In chronic and acute experiments on dogs, secretion of amylase and lipase in bile, under conditions of basal and stimulating feeding and before and after the ligation of pancretic ducts and i. v. administration of pancreatic gland tissue extract, was studied. Amylase and lipse were found to be normal physiologic components of the bile, the latter's secretion depending on functional state of liver and maintenance of enzyme in the blood. The transition of hydrolase from blood into the bile is considered to be one of mechanisms of securing the enzyme homeostasis. For starting amylo- and lipolytic activity of the bile, the processes of their recretion from the blood are considered to be very significant.
