Aim. To study cellular and humoral immunological parameters of the employees of production sites located at the former mining and uranium ore processing territories. Materials and methods. In this work the clinical laboratory and immunological methods of examination were used. Statistical processing of the results was performed by using nonparametric analysis methods in the StatSoft Statistica 6 software package. Results. 101 employees of Chepetskiy mechanical plant were examined at the age of 19-62. 76 (75.2%) of them contacted with industrial factor, 64 - with radiation and 12 - with chemical. 25 (24.8%) employees had no contact with industrial factor. The immunological examination of the employees in contact with industrial factor revealed laboratory signs of imbalance in the immune system with IgE-overproduction. The risk group for secondary immunodeficiency with the leading infectious syndrome was 15.8%. Conclusion. Changes of cellular and humoral parameters on average values were not revealed. Infectious syndrome - recurrent ETN viral infections (13.9%) and herpes virus infection (13.9%) prevailed in the structure of the employees of Chepetskiy mechanical plant. A statistically significant difference in the content (percentage and absolute) of CD16+ lymphocytes was found in the employees of Chepetskiy mechanical plant contacted with industrial factor. These results had no clinical significance, what can be considered as an adaptive response to the chemical factor.
