1. Mitochondria and microsomal fractions have been isolated from liver biopsies from patients with alcoholic cirrhosis, cryptogenic cirrhosis or chronic aggressive hepatitis. 2. Cirrhotic livers yieled fewer mitochondria than normal liver. 3. The most significant change was a decrease in mitochondrial respiratory control. Cirrhotic microsomal fractions had a 50% diminution in cytochrome b5 and cytochrome P-450 content. 4. The two patients with chronic aggressive hepatitis showed similar mitochondrial and microsomal changes.

We attempted to produce a model mouse with a liver injury resulting from an immunological mechanism in C57BL/6J mice, and the effect of hepatitis on the hepatic microsomal mixed-function oxidase system was studied. An experimental immunological liver injury model was caused by the intravenous injection of an anti-basic liver protein (BLP) antibody in mice which had been previously immunized with normal rabbit IgG (RGG) and complete Freund's adjuvant. C57BL/6J strain mice showed the highest susceptibility to the immunological liver injury. Typical histopathological changes in the liver included submassive hepatocellular necrosis and infiltration of lymphocytes into the portal tract and sinusoid area in a necrotic lesion. The liver injury in this model was markedly inhibited by the administration of prednisolone (20 mg/kg, p.o.), cyclophosphamide (15 mg/kg, i.p.), levamisole (10 mg/kg, p.o.), glycyrrhizin (50 mg/kg, i.p.) and cepharanthine (10 mg/kg, i.p.), which act on the immune system. Twenty-four hours after the injection of anti-BLP antibody, the activities of aminopyrine N-demethylase, aniline hydroxylase and NADPH-cytochrome c reductase and the content of cytochrome P-450 were mostly reduced, whereas cytochrome b5 and NADH-ferricyanide reductase were not. These results suggest that the experimental liver injury model in C57BL/6J mice is useful as a model of liver injury model, and its hepatitis was shown to inhibit the cytochrome P-450-dependent biotransformation of drugs in the mouse.

The aim of this work was to evaluate of efficacy and safety of complex Heptral, Vitamin B6 and Folic Acid in experimental hepatitis therapy compared with monotherapy. Experiments were carried out on pubertal rats. Eperimental hepatitis models were induced by Tetrachlormethane. The tetrachlormethane intoxication was reproduced by subcutaneous injection of CCL(4) 1ml/kg dissolved in 1ml of olive oil. Cytochrome P450, cytochrome b5, reduced glutation,activity of glutationetranspherase and content of ATP in hepatocytes were measured by the spectrophotometric techniques,but content of homocysteine by chromophtography techniques. Under CCL(4) intoxication disturbance of liver detoxication function, energy deficit and surplus of homocysteine were observed. Treatment of the toxic hepatitis with heptral increased the level of cytochrome P450, cytochrome b5, glutation activity of glutationetranspherase glutathione and reduced content of homocysteine. Complex therapy with Heptral and B6 and folic acid reveal more expressive hepatoprotective effect and safety than monotherapy with Heptral. Complex therapy improves not only the parameters of biotransformation (metabolic and conjugation phase), but also normalizes the level of ATP and homocystein. Vitamins B6 and folic acid increases the efficacy and safety of Heptral. This complex was recomended for treatment of hepatitis.
