Release of interleukin-1 beta from peripheral blood monocytes and its concentration in the blood serum of the workers employed at the production of chlorfenvinphos.

Our earlier investigations of people exposed to chlorfenvinphos revealed obstructive impairment of pulmonary function and changes in collagen metabolism. In order to evaluate the role of interleukin-1 beta in the development of these changes the serum interleukin-1 beta concentration and the ability of spontaneous and LPS stimulated production of interleukin-1 beta by monocytes were determined in 25 males aged 33-54 years and employed at the department producing chlorfenvinphos (its air concentration did not exceed permissible levels). Higher spontaneous production of interleukin-1 beta was found; the remaining parameters did not differ significantly as compared to the control group of 23 healthy males.
