[Changes in the interleukin-6 and interleukin-10 concentrations in the blood plasma of miners working in deep coal mines]

Blood plasma levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured in 45 miners working in a deep coal mine immediately after work shift using an immunoenzyme technique. The highest IL-6 level was recorded in those miners engaged in hard work under most adverse conditions of underground workings--it was found to exceed the control values. The same group of workers demonstrated the lowest level of IL-10 that differed from the control value. Miners aged between 41 to 50 years working in a coal mine, their underground service duration 16 to 20 years, displayed a decline in the level of IL-6. The coal mine miners with the 11- to 15-year service duration revealed an increase in the level of IL-10.
