Male Sprague-Dawley rats were divided into four experimental groups. Group 1 consisted of intact controls. Groups 2 and 3 received TZP-423810 mg/kg/day and CMA 50 mg/kg/day p.o., respective- ly, for 3 weeks. Group 4 received distilled water containing 2% Tween 80 instead of TZP-4238 or CMA. CMA caused marked atrophy of the adrenal gland. Histopathologically, the remarkable atrophy was observed in the adrenal cortical cells of zonae fasciculata and reticularis. Intracellular localization of glutathione-peroxidase (GSH-PO) which effectively reduces the lipid peroxides, was mainly observed in the cytoplasmic matrix (cytosol GSH-PO) near the mitochondria or lipid droplets. In ddition, immunoreactivi- ty of intramitochondrial GSH-PO (mitochondrial GSH-PO) was less than that in the controls.
