W pracy przedstawiono wyniki badań wpływu dichlorfosu, pestycydu fosforoorganicznego, na aktywność reduktazy HMG-CoA, kluczowego enzymu syntezy cholesterolu w wątrobie szczura w warunkach in vivo i in vitro.

he effect of dichlorvos, an organophosphorous pesticide, on HMG-CoA reductase activity was studied in rat liver in vivo and in vitro. Decreased reductase activity was noted both in acute (50% LD50) and repeated (10% LD50) exposure to dichlorvos. In vitro experiments did not show a direct effect of dichlorvos on the activity of the enzyme. The changes in HMG-CoA reductase activity may be explained by the disturbed permeability of the cellular membranes.
