[Lipid peroxidation in the liver of dogs and guinea pigs receiving chloditan].

The contents and the rates of the formation of lipid peroxides in the liver homogenates were studied. Dogs and guinea pigs were fed with chloditan in doses of 50 and 150 mg/kg body weight, respectively, for 20 days. In the dogs chloditan caused atrophy of the adrenal glands. The drug accumulation in the adrenal glands of the guinea pigs did not produce damage of the glands. The feeding with chloditan failed to change the level of malondialdehyde in the livers of the dogs and decreased it in the livers of the guinea pigs. In vitro spontaneous and NADP N-dependent lipid peroxidation in the liver homogenates of the dogs treated with chloditan was slowed. The decrease of malondialdehyde content in the guinea pig liver and the slowing of lipid peroxidation rate in the dog liver homogenate can be explained by the change in the activity of the enzymes detoxicating xenobiotics and products of lipid peroxidation.
