Experimental liver injury was produced in mice by the immunological technique. The utility of these models as an immunopharmacological method was investigated. The first model was produced by the injection of anti-basic liver protein (BLP) rabbit antibody into DBA/2 mice that had been previously immunized with rabbit IgG. The second liver injury was caused by injection of anti-liver specific protein (LSP) rabbit antibody into DBA/2 mice. The third model was produced by the injection of bacterial lipopolysaccharide (LPS) into Corynebacterium parvum pretreated ddY mice. In all injury models, extensive liver parenchymal cell damage was estimated by elevation of glutamate transaminase (GOT and GPT) activity. These were confirmed by histopathological studies of the liver. Typical histopathological changes in the liver from injured mice were submassive hepatocellular necrosis and infiltration of granulocytes and lymphocytes into the portal tract and sinusoid in the necrotic lesion. Administration of prednisolone and cyclophosphamide for 10 days prior to injection of eliciting antibodies or LPS suppressed the elevation of serum transaminase levels in all experimental liver injury models. Cianidanol and sylibin inhibited the elevation of GOT and GPT in anti-BLP induced liver injured mice. These evidences suggest that the above models are suitable for investigating the remedy for liver diseases.

Effects of cianidanol on chronic liver injury induced by prolonged administration of carbon tetrachloride (CCl4) and on liver regeneration after partial hepatectomy of normal liver and CCl4 chronically injured liver were investigated by the measurement of plasma and liver biochemical parameters. Cianidanol increased the total plasma protein and 14C-Leu incorporation into plasma protein, while it reduced the contents of liver cholesterol and triglycerides. In rats with chronically injured liver or regenerating liver after partial hepatectomy of chronically injured liver, cianidanol improved the retention rate of BSP and the content of liver sugar. In rats with chronically injured liver, plasma GPT and GOT activities were reduced with the administration of cianidanol. Cianidanol had no effect on the regeneration rate after partial hepatectomy of normal liver, but it increased the regeneration rate after partial hepatectomy of chronically injured liver. These results suggest that cianidanol has the effect of improving the function of liver cells damaged by CCl4 treatment and of promoting the recovery of cell function to a normal level.
