[Cytochemical analysis of selected dehydrogenases in peripheral blood leukocytes of workers exposed to polychlorinated pesticides].

In 36 workers occupationally exposed to polychlorinated pesticides (Gammexane, DDT) and in a control group, cytochemical investigations of lactate and succinate dehydrogenases (LDH and SDH, respectively) in peripheral blood leukocytes were performed. In comparison with the control group, in workers exposed to pesticides, reduction of colour intensity in neutrophiles for SDH and in lymphocytes both for SDH and LDH was observed. In discussion, an attempt was made to interpret the obtained investigation results which seem to indicate disturbances in pyruvate metabolism in peripheral blood lymphocytes.
