Influence of age and sex on pseudocholinesterase activity of Korean adults / 대한마취과학회지

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 tbere was no intersexual difference. These findings suggest that adults before the age of 50, male has higher pseudocholinesterase activity than female.
