[The experimental pharmacotherapy of the liver lesion induced by indomethacin].

In experiments on albino rats it was established that three administrations of indomethacin in a dose of 0.01 g/kg body weight induced a severe damage of the liver characterized by disturbances of hepatocytic membranes, bile-producing and protein-producing functions of the liver, an enhancement of lipid peroxidation, a decrease of reduced glutathione pool. Antioxidants (tocopherol acetate, essentiale, legalon, flacumin) limit manifestations of indomethacin, hepatotoxicity, as a result of which tha functional-biochemical disorders in the liver show up to a lesser degree.

[Liver function and lipid peroxidation in indomethacin-induced damage].

Administration of indomethacin in a dose of 0.01 and especially in a dose of 0.02 mg/kg body weight three times was found to cause a severe damage of the liver.

[Hepatotoxic effect of a combination of pyrazinamide with isoniazid and rifampicin].

Experiments on rats showed that 14-day exposure of the animals to pyrazinamide in a dose of 1.5 g/kg induced marked disorders in cholopoiesis and lowering of the reduced glutathion levels in the liver. When pyrazinamide was used in combination with isoniazid or rifampicin a marked increase in the activity of aspartate and alanine aminotransferases in blood serum and induction of lipid peroxidation in the liver were observed in addition to the disorders in cholopoiesis and lowering of the reduced glutathion levels.
