An evaluation of continual determination of blood cholinesterase activity for inhibition studies

Simple method of continual monitoring of the rat blood cholinesterase activity in vivo was used to demonstrate its inhibition following i. m. administration of acridine and carbamate inhibitors. Another type of inhibition was demonstrated for different routes of administration of highly toxic organophosphate, VX. Reactivation of the blood cholinesterase was also monitored following intoxication with VX and soman and treated with obidoxime and atropine. This continual determination of cholinesterase activity represents an useful approach to study effects of cholinesterase inhibitors.
