title: [Interaction of membrane-bound and solubilized acetylcholinesterase from human and bovine erythrocytes with organophosphorus inhibitors].
abstract: Differences are found between the membrane-bound and soluble acetylcholinesterases of human and bovine erythrocytes when the enzyme interacts with organophosphoric inhibitors in the presence of acetylc choline and galantamine, a reverse inhibitor of acetylcholinesterase. In most cases prevention of inhibition of the soluble enzyme activity necessitates a higher (2-3 times higher) concentration of the protecting agent than protection of the membrane-bound enzyme. Concentrations of acetylcholine and galantamine providing a 50% protection of the enzyme did not practically depend on the strength of the anticholinesterase action of organophosphoric inhibitors.
