title: Early destruction of cytochrome P-450 in testis of carbon tetrachloride poisoned rats.
abstract: There is 20--36 percent decrease in the microsomal cytochrome P-450 (P450) content of the testes 3 or 6 h after CCl4 administration to Sprague--Dawley male rats. Irreversible binding of CCl4 metabolites to testicular microsomal lipids is observed as early as 3 h while CCl4 induced lipid peroxidation does not occur within the first 6 h of poisoning. Results suggest that reactive metabolites rather than lipid peroxidation is involved in P-450 destruction in the testes.
