[Subcellular distribution of acid hydrolases in rat liver during toxic hepatitis].

Changes occurring in the lysosome population were assessed by the results of studies of intracellular distribution of the marker lysosome enzymes--acid phosphatase and acid RNAase. An acute (pure CCl4-0.15 ml per 100 g of weight into the stomach) and chronic (inhalation poisoning after Rabinovici and Wiener) toxic hepatitis was accompanied by an increase in the specific activity of the enzymes in the fraction of heavy mitochondria, this pointing to the change in the sedimentation properties of the lysosomes. An increase in "nonprecipitable" activity of the acid RNA-ase in chronic toxic hepatitis served as the sign of injury of the lysosome membranes.
