title: [Role of the liver in the regulation of blood levels of insulin, C-peptide and glucose].
abstract: Insulin, C-peptide and glucose levels in the blood, collected from the portal, hepatic and femoral veins of 7 young healthy dogs were studied before and 3 to 45 minutes after intravenous glucose injection. It was found that insulin concentration in the peripheral vein does not reflect completely its secretion by pancreatic islets, since a considerable part of hormone, released after glucose injection, is retained by the liver. C-peptide concentration in the peripheral veins reflects more precisely the beta-cell secretory activity that insulin level. A rise of insulin concentration in the portal vein after intravenous glucose injection promotes the hepatic glucose assimilation.
