RESUMO
Influence of anabolic drug (phenobolin) injection at a dose of 2.5 mg/kg on some indexes of blood, reproductive system, the level of thyroid hormones, corticosterone and testosterone in blood serum of the male rats exposed to a fractional irradiation at the total dose of 2.0 Gy have been studied. A significant decrease in the quantity of leucocytes and lymphocytes after a fractional irradiation without and with phenobolin introduction was determined. Introduction of anabolic drug resulted in a significant drop of relative mass of testes and, particularly, epididymes, and also in a sharp decrease of the number of mature germ cells isolated from epididymes. A combined action of phenobolin and fractional irradiation (2.0 Gy) led to a significant reduction (3-5 times) in the quantity of mature germ cells in an epididymis. In some cases phenobolin influenced the level of testosterone in blood serum of the intact and irradiated animals. The anabolic steroid drug affects negatively the state of reproductive system of male rats.
