The mechanism of insulin secretion after oral glucose administration. VII. Exocrine pancreatic function and plasma-IRI in dogs with chronic pancreatic fistulas.
During an intravenous glucose test, conscious dogs with exocrine pancreatic fistulas showed a reduction in the secretions of water, protein and of bicarbonate. This reduction is related to hyperglycemia and to IRI increase in the peripheral venous blood. After oral administration of glucose, however, a biphasic stimulation of the exocrine function was observed. During the first 15 minutes when insulin secretion increases independently of the blood glucose increase, all exocrine pancreatic functions are transiently stimulated, too. A second peak of the exocrine secretions is to be observed when glucose absorption and insulin secretion exhibit their maximum.
