CHOLINESTERASE LEVELS IN PLASMA AND TISSUES

Abstract

Changes in the level of pseudo-cholin-esterase in the plasma of male rats do not entail similar changes in the level of true cholinesterase in the plasma. Changes in the level of true cholinesterase in the plasma do not necessarily reflect changes in the level of this enzyme in brain and muscle. Consequently, the activities of the cholinesterases of plasma cannot serve as an index of the level of true cholinesterase in tissues under pathological conditions.
