Biological studies in childhood schizophrenia: plasma and RBC cholinesterase activity.
Most investigations of possible metabolic aberrations in childhood schizophrenia failed to demonstrate differences between schizophrenic patients and control groups. Cholinesterase activity has net been previously reported in schizophrenic children. Similar studies with adult schizophrenics have hot been consistent, despite some reports of abnormal cholinesterase activity. The present study rep...
متن کاملInfluence of ketamine on human plasma cholinesterase.
The influence of ketamine upon human plasma cholinesterase (E.C. 3.1.1.8) was determined by means of a colorimetric assay technique at 25 degrees C, pH 7.7 with butyrylthiocholine as substrate. Ketamine caused a reversible inhibition of cholinesterase (pI50= 2.75; apparent Ki=4.94X10(-4) M). The kinetic analysis of the inhibitory action revealed a mixed competitive/non-competitive type of mecha...
متن کاملStudies Ox Cholinesterase*
Recent investigations have provided evidence that the release and removal of acetylcholinc is an intracellular process directly connected with the nerve action potential. The experiments suggest that the ester renders the neuronal surface permeable to all ions and thereby depolarizes the membrane (l-4). This concept is based mainly on studies of the enzyme cholinesterase. Three essential featur...
متن کاملPlasma cholinesterase and malignant hyperthermia.
Sir,—Humphrey, Downing and Brock-Utne (1980) are less than accurate in describing the destiny of expiration switched to inspiration in the Johannesburg Circuit. They vaguely refer to experimental evidence gathered "while studying a similar system"—evidence which simply does not tally with known pharmacokinetic principles. With a fresh gas inflow of 70mlkg~' min"' in a patient weighing 65 kg, th...
متن کاملEffect of pre-eclampsia on plasma cholinesterase activity.
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...
