this study investigates the effects of melatonin on the sperm quality and testis weight after the combination of swimming exercise and nandrolone decanoate (deca). two groups of male wistar rats were treated for eight weeks as follows; group a consist of co (control), sham, n (deca), s (swimming) and ns (deca plus swimming); and group b: sham m (sham melatonin), m (melatonin), mn (melatonin plu...

introduction: anabolic – androgenic steroids (aas) are used at high doses by athletes for improving athletic ability, muscle mass and physical appearance. unfortunately, the abuse of these agents has been significantly increased. it has been established that exercise and high doses of aas may influence the hypothalamic-pituitary-gonadal axis, which can in turn affect testicular apoptosis and ma...

Bone tissue has been shown to contain numerous cell-to-cell signaling peptides called growth factors. These growth factors are thought to have important regulating effects for bone remodeling, due to their potent effects on bone cell metabolism. Our investigation was intended to assess the effect of nandrolone decanoate and calcitonin treatment on biochemical markers of bone formation (bone alk...

INTRODUCTION Anabolic steroid is an established drug for treating catabolic states. The said drug has been shown to restore the lean body mass, to prevent osteoporosis and to correct the impaired immune response, but only few studies have evaluated the effect of the same on fracture healing. METHODS Fracture was produced by an impact device in 24 rabbits which were divided into experimental (...

conclusions chronic administration of high doses of nd can alter serum fsh, lh and testosterone and hematological parameters in male rats. results serum testosterone, lh, fsh, weight gain, food and water intake in group t were significantly decreased compared to other groups (p < 0.05). in addition erythrocyte, leucocytes, hemoglobin and hematocrit in group t were significantly increased compar...

BACKGROUND Until now, no experimental study has directly assessed the arrhythmogenesis of chronic consumption of anabolic androgenic steroids along with moderate-intensity endurance exercise. OBJECTIVES We evaluated the influence of integration of anabolic androgenic steroids along with moderate-intensity endurance exercise on susceptibility to lethal ventricular arrhythmias in rat. MATERIA...
