[Destructive and reparative processes in the liver in acute experimental peritonitis].

Dynamics and character of interrelations of destructive and reparative processes in the liver in different conditions of acute experimental peritonitis (AEP), using preparations, inhibiting or stimulating these reactions in the experiment with 135 white rats have been studied. It was established the dependence of the level of destruction and intensity of hepatic reparative regeneration on the gravity of peritoneum affection, the level of toxicity and the state of the body immunologic reactivity. The organ reparation in normal AEP in the first two days is carried out mainly by intercellular hyperplasia of hepatocyte ultrastructures. Karyokinetic cellular activity is increasing from the 3rd day and reacting its peak on the 4-5 day of the experiment. The course of peritonitis while introducing azathioprine is accompanied by prevailing destructive-purulent changes in the liver. On the contrary, levamisole administration in experimental animals causes an increase in lymphoid-cellular infiltration of stromal and parenchymatous cells with earlier reparation of necrotic foci.
