Plasma cholinesterase (PCHE) activity was determined using a colorimetric method in 11 healthy non-pregnant women, 11 healthy pregnant women at term, and 11 pre-eclamptic pregnant women at term. The mean plasma cholinesterase activities for healthy non-pregnant women, healthy pregnant women and pre-eclamptic pregnant women were 438 +/- 81,257 +/- 25 and 173 +/- 18 units . ml-1, respectively. Ou...

伴 隆志 ・永田 親 義 The inhibition of cholinesterase by some of carbamates has attracted the attention of many researchers in relation to the clinical usefulness (1) and insecticidal activity (2, 3) of the compounds. In this paper the author's chief concern is mainly devoted to investigating the rela tionship between the electronic structure of several structurally related carbamate type cholinesteras...

OBJECTIVE To review the literature relating to the use of acetyl cholinesterase inhibitors in Parkinson's disease dementia (PDD). METHOD MEDLINE (1966--December 2004), PsychINFO (1972--December 2004), EMBASE (1980--December 2004), CINHAL (1982--December 2004), and the Cochrane Collaboration were searched in December 2004. RESULTS Three controlled trials and seven open studies were identifie...

This report assesses the value of cholinesterase (ChE) activity as an indicator of liver function and analyses its usefulness in the diagnosis of jaundice. A rapid method of determination has been used, and alterations in ChE activity in conditions other than liver disease have been studied to permit a fuller and more accurate survey of its value as a liver function test. The level of serum cho...

The kinetic characteristic (Km) of cholinesterase from the crab Chasmagnathus granulata, the shrimp Farfantepenaeus paulensis and the fish Odontesthes bonaeriensis were compared and correlated with the anticholinesterasic effect of eserine (physostigmine). For the crustaceans, the estimated Km values were about 5-8 times higher than that estimated for the fish (0.04 mM). In the crab and the shr...

We developed an enzyme immunoassay (ELISA) for quantitation of plasma cholinesterase substance concentrations in native plasma or serum samples. The ELISA assay is based on polyclonal (rabbit) antihuman cholinesterase and a highly specific monoclonal (mouse) antibody, with a commercially available peroxidase-conjugated (rabbit) antibody directed against mouse immunoglobulins as the signal carri...
