Journal ArticleDOI
Regional differences in microsomal lipid peroxidation and antioxidant levels in the guinea pig adrenal cortex.
D.A. Staats,Howard D. Colby +1 more
TL;DR: There are regional differences in adrenocortical LP which may be caused by differences in tocopherol content and alpha-Tocopherol may serve important antioxidant functions within the adrenal cortex, thereby contributing to the functional zonation of the gland.
Journal ArticleDOI
Conversion of spironolactone to 7α-thiomethylspironolactone by hepatic and renal microsomes
TL;DR: The results indicate that the liver and kidney are potential sites of 7α-thiomethyl-SL production and that its formation probably does not involve the C-S lyase pathway.
Journal ArticleDOI
Species differences in adrenal spironolactone metabolism: relationship to cytochrome P-450 destruction
Journal ArticleDOI
Effects of cadmium in vitro on microsomal steroid metabolism in the inner and outer zones of the guinea pig adrenal cortex
TL;DR: The results indicate that cadmium produces both quantitative and qualitative changes in adrenal microsomal steroid metabolism and that the nature of the changes differs in the inner and outer adrenocortical zones.
Book ChapterDOI
Fate of Anabolic Steroids in the Body
TL;DR: The anabolic steroids used by athletes are various synthetic derivatives of testosterone, substances with longer durations of action and/or greater potencies than the physiological androgens.
