title: Plasma cholinesterase activity in early pregnancy.
abstract: A significant fall in plasma cholinesterase activity was observed in six healthy young women in the first 3 months of normal pregnancy. There was some evidence of return to normal pre-pregnancy levels in later pregnancy. No hypothesis is suggested to account for this phenomenon, although it seems possible that it may be the result of altered liver enzyme synthesis.
