Fractional and molar rates of lecithin:cholesterol aminotransferase (LCAT)-catalyzed reaction were decreased, while free cholesterol fraction was increased in blood serum of rats within 24 hrs after single administration of CCl4 I mg/kg. Cathergene, contributing to a decrease in hepatocyte necrosis, affected positively the blood lipid spectrum in CCl4 treated rats. The cathergene protective effect, observed also after acute ethanol poisoning (6 g/kg), involved an increase by about 30% of the fractional and molar rates of LCAT-reactions; it also normalized the cholesterol esterification coefficient in blood serum. The drug did not prevent the postalcohol dystrophy of hepatocytes, hypertriglyceridemia, hypercholesterolemia.
