Serum pseudocholinesterase activities, using butyrylthiocholine as substrate, measured in 639 employees of Korea Cancer Center Hospital in 1993.
Overall mean value of pseudocholinesterase was 9.38±2.10 U/ml, 10.6±2.10 U/ml in male, and 8.58±1.67 U/ml in female, respectively.
Male in the first five decades of life had higher pseudocholinesterase activity than female, and after the age of 50 there was no intersexual difference. These findings suggest that adults before the age of 50, male has higher
pseudocholinesterase
activity than female.
