Effects of carbon tetrachloride on isolated rat hepatocytes. Inhibition of protein and lipoprotein secretion.

The effects of carbon tetrachloride on protein and lipoprotein secretion, and on lipid peroxidation, have been investigated in isolated rat hepatocytes. It was found that although the free-radical scavenger promethazine completely suppressed the increased peroxidation produced by carbon tetrachloride, it had no effect on the inhibitory action of carbon tetrachloride on lipoprotein secretion. In consequence, the latter effect of carbon tetrachloride does not appear to be mediated through a peroxidative stage.
