To investigate the change of the portal venous pressure (PVP), conjugated glycocholic acid (CGA) and pancreatic glucagon (PG) concentration in rats peripheral and portal venous blood in the course of experimental liver cirrhosis induced with carbon tetrachloride and to investigate the mentioned changes after portalazygous devascularization. The authors found that in the early stage of cirrhosis the PVP and the concentration of CGA and PG in peripheral venous blood were increased markedly, CGA in portal vein was decreased and PG in portal vein was increased in early stage of liver cirrhosis.With the extent of liver cirrhosis the indexes above changed more markedly. After portalazygous devascularization the concentration of CGA in peripheral vein in the cirrhotic rats was increased but PVP, the concentration of CGA in portal vein and PG in peripheral and portal vein did not change.There was no change in nornal rats. The results suggest that the variation in CGA in peripheral vein can accurately reflect the degree of damage to liver cells, thus making the diagnosis of liver cirrhosis earlier and judging the degree and prognosis of liver cirrhosis.The concentration of PG in portal venous and peripheral vein relate to PVP in liver cirrhosis.Portalazygous devascularization can maintain PVP and PG in portal vein and do not affect liver function of the control rats but it can damage liver cell in cirrhotic rats.
