title: Effects of 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic acid on peroxisomal enzymes in rat liver.
abstract: The effects of feeding 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) on the level of peroxisomal enzymes in rat liver were studied. The concentration of triglyceride in serum was decreased and the activity of cyanide-insensitive palmitoyl-CoA oxidation, catalase and carnitine acetyltransferase increased. However, the extent of the increase in the activity of these enzymes by treatment with 2,4-D was less pronounced than that by 2,4,5-T treatment. The administration of 2,4-D or 2,4,5-T increased the concentration of polypeptide with a mol. wt of 80,000 in the light mitochondrial fractions of the liver from the rats.
