Title: Lipid peroxidation in the adrenal glands of male rats exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).

Authors: Bestervelt, L L; Piper, D W; Pitt, J A; Piper, W N

Published In Toxicol Lett, (1994 Feb 01)

Abstract: This study was performed to determine whether TCDD (50 micrograms/kg; single oral dose) could induce adrenal microsomal lipid peroxidation, which might be correlated to decreased levels of cytochrome P-450 and 21-hydroxylase activity. The amount of malondialdehyde (MDA) formed was significantly higher than controls at days 1 through 5 following TCDD treatment. Microsomal cytochrome P-450 levels were depressed after lipid peroxidation at days 1, 3, and 5, and 21-hydroxylase activity decreased at day 5 after TCDD treatment. This study shows that TCDD stimulates adrenal microsomal lipid peroxidation which is associated with decreased cytochrome P-450 levels and 21-hydroxylase activity.
