[Dynamics of acid phosphatase activity in the liver in the process of involution of cirrhosis].

Changes in the total activity of acid phosphatase in the liver as well as changes in the enzyme activity in hepatocytes and connective tissue cells of fibrosis layers were investigated, using quantitative histochemical method, in the process of mouse cirrhosis involution. After discontinuation of CCl4 injection, the animals with cirrhosis were divided into two groups. In the first group the resection of the left lobe of the liver was performed. The animals of the second group were not subject to operation. The results demonstrate that there is a close correlation between lysosomal hydrolase activity of hepatocytes and connective tissue cells of the liver and collagen resorption during cirrhosis involution. The most intensive lysis of collagen takes place within the first three weeks of cirrhosis involution in both experimental groups. Partial resection in cirrhosis has no significant effect on the changes and level of total activity of lysosomal hydrolase enzymes in the liver during cirrhosis involution.
