title: [Cholinesterases (acetyl and pseudocholinesterase) in human amniotic fluid].
abstract: Study on 41 cases. The cholinesterasic activity of human amniotic fluid, free from blood, is very weak, in average 0,10 microkatal, approximatively 300 times weaker than mother's serum. In this "total cholinesterase", we find a large amount (about 40%) of acetylcholinesterase. Amniotic cholinesterases have an prominent placentary origin, with, in addition, a likely activity proceeding from cellular elements.
