摘要：Rat and human erythrocytes cholinesterase and purified bovine erythrocytes cholinesterase were used as an enzyme and the effect of phenylmercuric acetate and ethylmercuric phosphate on these enzymes was studied. The enzymic activities were examined by the determination of the amount of unreacted acetylcholine by the method of hestrin. Both organic mercury compounds inhibited these enzymes and the inhibition was expelled by the addition of cysteine. It was proved that PMA inhibited bovine erythrocytes cholinesterase competitively and that EMP inhibited it non-competitively.
