Lycopene protects against renal cortical damage induced by nandrolone decanoate in adult male rats

Abstract

Nandrolone decanoate is an anabolic androgenic steroid that is abused worldwide by young athletes and bodybuilders to enhance their physical performance. Many clinical reports among those abusers demonstrated a variety of renal disorders. Lycopene is one of the dietary carotenoids found in fruits like tomato, watermelon, and grapefruit and has attracted considerable attention as an antioxidant. Therefore, the present study was designed to evaluate the protective effect of lycopene against nandrolone decanoate induced renal cortical damage. Forty adult male rats were equally divided into four main groups: group I served as the control, group II received lycopene 4 mg/kg/day, group III received nandrolone 10 mg/kg/week, and group IV received nandrolone and lycopene at a dose similar to the previous groups. At the end of the experiment, urea, creatinine and oxidative stress indicators were measured, then the kidneys were sampled for histopathological and immunohistochemical studies. Sections of the group (ПI) showed variable histopathological alterations in the form of distorted shrunken glomeruli and almost complete loss of the glomerular capillaries, in addition to vacuolation and shedding of the tubular epithelium. In conclusion, these results showed that nandrolone decanoate induced toxic effects in the kidney of rats and lycopene had protective effects versus such evoked renal damage.
