肝硬変に対する肝動脈結紮術の実験的研究 第3編 実験的肝硬変の肝動脈結紮の影響肝機能及び赤血球について

1) Various studies of urine, erythrocyte and serum have been performed following hepatic artery ligation both in rats in whom liver cirrhosis had been produced by carbon tetrachloride and in normal rats. 2) Abnormal findings found in rats with liver cirrhosis are gradually restored to normal following simple laparatomy without hepatic artery ligation. 3) Damages of the liver caused by hepatic artery ligation are detected in these studies in both rats with liver cirrhosis and normal rats. However, degree of damage is less severe in the former considering already exsistent abnormal condition before ligation of hepatic artery. 4) Rats with cirrhosis of the liver tolerate well ligation of hepatic artery indicating that they have still more reserve than minimum neccessary to keep their lives. 5) Ligation of hepatic artery has its place as a supplemental means for symptomatic relief in surgical treatment of liver cirrhosis. However, it is believed that improvement of liver function should not be expected by this method.
