Abstract
Summary
The concentrations of amylase and lipase in peripheral venous blood, portal blood, and thoracic duct lymph are equal in fasting anesthetized dogs. An increase of amylase in the blood often appears 5 to 10 minutes after damaging the pancreas. The increase of blood amylase and lipase following injury of the pancreas or retention of its secretion is due mainly to the inflow of pancreatic enzymes into the general circulation by way of the portal vein and to a smaller extent to inflow of enzymes by the lymph of the thoracic duct.
