[Effect of immunomodulating drugs on the release and activities of lysosomal proteinases of the liver of rats with ethanol poisoning].

Increased activity of cathepsin A and D in the cytosol fraction and homogenate of the liver of rats intoxicated for 4 weeks with ethanol (0.6 g/100 g of the body weight) was found. The cytosol cathepsin A and D activities were unaffected under the influence of Levamisole and isoprinosine++. Encorton reduced the activity of both cathepsins in the cytosol fraction while it did not diminish their activities in the liver homogenates. Encorton, and to a markedly lesser degree, Levamisole and isoprinosine++ caused a regression of vacuolar degeneration and of necrotic lesions and an increase in the number of glycogen granules in the livers of ethanol-intoxicated rats.
