Abstract

Anabolic androgenic steroids are the xenobiotic substrates that are metabolized in the body by the protective enzyme systems. Mixed function oxygenase enzymes include a group of enzymes which play an essential role in the metabolism of a broad range of xenobiotics including endogenous and exogenous substrates. Cytochrome P-450, a member of mixed function oxygenase enzymes, plays an important role in oxidative metabolism of drugs and xenobiotics entering human body. Various anabolic steroids are found either to increase or decrease the activity of cytochrome P-450. However, effect of nandrolone decanoate, most commonly abused anabolic steroid, on cytochrome P-450 activity is still fragmentary. In the present study, albino mice were administered intramuscular 2.5 mg of nandrolone decanoate injection at 15 days interval. Cytochrome P-450 activity is determined by following the method of Omura and Sato (1964) in liver and kidney tissues of both normal and experimental groups upto 90 days. Investigation shows a significant (p <0.01) increase of cytochrome P-450 (nmol/mg) activity in liver tissue as compared to that of kidney tissues. A tissue specific and dose specific increase of cytochrome P-450 activity is observed. Mean cytochrome P-450 is found highest in liver tissue on 45(th) day whereas the activity in kidney tissue is noticed on 90(th) day of treatment. From the above observation, nandrolone decanoate can be suggested as a potent inducer of cytochrome P-450 activity like other anabolic steroids.
