[Acid phosphatase and non-specific esterase activities in peripheral blood lymphocytes of coke plant workers].

In 32 workers of coking plants cytoenzymatic reaction was examined in lymphocytes peripheral blood to determine the presence of acid phosphatase and unspecific esterase expressed in total score values. Statistically significant decrease of unspecific esterase activity and lower mean values of acid phosphatase activity were found as compared to the results obtained in the control group. It seems that periodical determinations of cytoenzymatic activity of unspecific esterase in lymphocytes of peripheral blood may be useful in assessment of biological effects of occupational exposure in coking plants workers.
