The effect of acute portacaval shunting in dogs on cerebral and peripheral blood flow and metabolism.

Cerebral blood flow and metabolism in hepatic cirrhosis before and after portacaval shunt operation.

It has been demonstrated that cardiac output and pulmonary, gastroduodenal, pancreatic, and splenic blood flow increases after portacaval shunt operations. This report concerns a study of cerebral haemodynamics and metabolism in eight patients with cirrhosis of the liver, examined both before and after portacaval surgical anastomosis. The patients were fully alert and orientated to mental and n...

A Multiple Catheter Technique for Studies of Hepatic Metabolism and Blood Flow in Dogs with Portacaval Transposition Studies on Hepatic Blood Flow and the Rate of Bkomsulphalein Clearance in Dogs with Portacaval Transposition

The Effect of Hurdling Performance on The Adaptive Profile of Cerebral Blood Flow in Vestibular Irritation

Background: The reactions of the whole organism that occur under the action of accelerations of rectilinear and rotational motion are factors that have a systemic effect on the cerebral blood flow. The use of hurdling performance in the structure of human physical activity can have a significant impact on the tone of the brain vessels, their elasticity and venous outflow in the development of f...

The effect of portacaval shunt upon hepatic cholesterol synthesis and cyclic AMP in dogs and baboons.

Hepatic cholesterol synthesis. hepatic cyclic AMP, and portal and peripheral insulin and glucagon levels were investigated in nine dogs and three baboons after complete portacaval shunt. Cholesterol synthesis as measured with acetate incorporation was reduced in both species, Hepatic cyclic AMP increased in dogs, Changes in portal and systemic insulin were inconsistent. but hyperglucagonemia oc...

Diurnal rhythm returns to normal after elimination of portacaval shunting.

Previous studies showed that portacaval shunting causes metabolic and behavioral changes in rats. Most metabolic changes reversed within 1-2 wk after restoration of normal circulation. However, the rate of cerebral glucose metabolism (CMRGlc) remained depressed in some areas. The question arose whether complete recovery was possible. Therefore, a long-term behavioral study was undertaken to det...
