[Protein-synthesizing apparatus of the rat liver and placenta during damage of the biomembrane by tetrachloromethane and the administration of methylxanthines].

Treatment of rats with tetrachloromethane was accompanied by a decrease in total ribosomal material, an increase in free, unbound with membranes, polyribosomal fraction and marked decrease in 14C-leucine and 3H-orotate incorporation into proteins and RNA of liver and placenta cells. Administration of methylxanthines--euphylline and trental protected the protein-synthesizing apparatus of hepatocytes and placenta from the damaging effects of tetrachloromethane. The role of microsomal monooxygenase system in tetrachloromethane activation and in impairment of cAMP-dependent regulation of translation process under conditions of xenobiotic-induced cell injury are discussed.
