  • Title: Carbon tetrachloride and bromotrichloromethane toxicity. Dual role of covalent binding of metabolic cleavage products and lipid peroxidation in depression of microsomal calcium sequestration.

    Abstract:
    We have investigated the importance of covalent binding and lipid peroxidation on the depression of microsomal calcium sequestration associated with in vitro metabolism of 14CCl4. Studies with CBrCl3 are also reported. In aerobic systems, promethazine was used to block lipid peroxidation, measured as malondialdehyde (MDA) generation. Effects of low levels of lipid peroxidation were tested in Fe2+-supplemented systems free of halogenated hydrocarbons. The results indicate that microsomal calcium sequestration can be depressed significantly by metabolism of either CCl4 or CBrCl3 in the absence of MDA generation, or by lipid peroxidation occurring in the absence of halogenated hydrocarbons.
