title: Effects of carbon tetrachloride on the liver of chickens. Early biochemical and ultrastructural alterations in the absence of detectable lipid peroxidation.
abstract: Administration of CCl4 i.p. to Leghorn chickens did not promote lipid peroxidation of liver microsomal lipids, as evidenced by either increased diene conjugation or by decreased arachidonic acid content. The hepatotoxin did not produce liver necrosis 24 h after dosing, but decreased the cytochrome P-450 content, and aminopyrine N-demethylase and glucose 6 phosphatase activities at 1, 3, 6 and 24 h. CCl4 administration produced dilation of the rough endoplasmic reticulum and detachment of ribosomes from their membranes. These observations suggest that lipid peroxidation is not the key event in the production of these biochemical and ultrastructural alterations, elicited by CCl4.
