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.

The state of hematopoietic, reproductive and endocrine systems of the organisms of male rats and their offspring in generations (F0-F1-F2) was studied, and the sensitivity of an organism to the action of carcinogen (Af mice) after a stay in the ChNPP exclusion zone was analyzed. It was ascertained that the most significant changes of the morphofunctional state of the animals were observed in the II generation (F2), which remained for a long period under the conditions of radioactive contamination. We have revealed an increased number of leukocytes, neutrophils, lymphocytes, and, especially, monocytes as against while the decrease in the number of erythrocytes and haemoglobin content; the decrease of thyroid function and cortical layer of the adrenals as opposed to while the increase in the relative weight of testes and their epididymides and the decrease in the number of spermatocytes and spermatozoa in the testis tissue. The exposure of Af mice in the exclusion zone increases the processes of mutagenesis and carcinogenesis, and changes the organism response to standardized action of chemical carcinogen. The increase in the exposure time of animals intensifies metabolic processes in a cell and increases their sensitivity to the action of xenobiotics.
