The in vitro effect of procainamide on plasma cholinesterase (PCHE) activity in the plasma of ten normal ASA physical status I patients was studied using a kinetic method. The mean plasma cholinesterase activity without procainamide (control) was 0.90 +/- 0.09 units.ml-1. The dibucaine numbers of all the samples were in the normal range of 78 to 86, indicating normal genotypes. The mean plasma ...
in this study, a commercially available kit in which propionylthiocholine is used as a substrate and a dibucaine solution to determine the variants of the enzyme were utilized. plasma cholinesterase activity of 151 patients who underwent different operations was measured during a period of six months. the mean±sd of the enzyme activity in 150 patients was 4.39±1.17 ku/l .. seventeen patients (1...
Background: Organophosphates use in agriculture and concern about their effects on human is increasing. This study was conducted to investigate the activity of blood cholinesterase in sprayers. Methods: In a descriptive and analytical cross-sectional study, 60 (30 sprayers and 30 control individuals) with age range of 29-62 years, mean age of 44.33±8.55 years were studied and the results were ...
organophosphate chronic toxicity has been evaluated in this study. biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. we have studied 17 occupationally exposed persons to pesticides. using ellman's colorimetric method, their plasma cholinesterase activities have been measured. results show that the appea...

BACKGROUND Plasma cholinesterase activity is known to be correlated with plasma triglycerides, HDL- and LDL-cholesterol, and other features of the metabolic syndrome. A role in triglyceride metabolism has been proposed. Genetic variants that decrease activity have been studied extensively, but the factors contributing to overall variation in the population are poorly understood. We studied plas...
Erythrocyte and plasma cholinesterase activities were measured biweekly in one group of 22 subjects for a year and daily for three weeks in another group of nine men. The average range [i.e., (range/mean) X 100] of activity of erythrocyte cholinesterase in men during a year was 8% and during three weeks was 5%. For plasma, the corresponding values were 25% and 12%. The average ranges for erythr...
Erythrocyte acetylcholinesterase and plasma cholinesterase was estimated in 50 normal pregnant women and 22 age matched normal non-pregnant women. Plasma cholinesterase was significantly decreased while erythrocyte cholinesterase was significantly increased during pregnancy. These changes may be related to altered haemodynamics and or other inter-related changes occurring in pregnancy.
