Study on the Hepatic Circulation : Part I : A Method for the Measurement of the Ratio of Hepatic Arterial and Portal Flow with the Electric Conductivity Method

The theory and the procedure for the measurement of the ratio of hepatic arterial and portal flow with the method of electroconductivity, using saline as an indicator were reported. The ratio of hepatic arterial and portal flow of healthy dogs was 16.5±10 : 83.5±10 in average. And then studies were performed the hepatic circulation in hypoxic state and experimental pulmonary embolism of dogs. In hypoxic state, the portal flow was increased remarkably with the ratio of hepatic arterial flow decreased. In pulmonary embolism, increased hepatic arterial flow and decreased portal blood flow were demonstrated.
