Chlordecone potentiation of CCl4 hepatotoxicity in ovariectomized rats.

abstract：:The contributions of the hepatic microsomal and cytosolic fractions in the metabolic activation of the promutagen 2-aminofluorene into mutagenic intermediates in the Ames test were investigated. Rat hepatic postmitochondrial, microsomal and cytosolic preparations could convert 2-aminofluorene to mutagens, the postmito...
