Abstract

This study was undertaken to furthur define the characteristics o f subsensitivity produced by chronic administration of cholinesterase inhibitors and to attempt to elucidate a possible mechanism by which it occurs. Administration of disulfoton, echothiophate , parathion and OMPA to rats for eight days resulted in a decreased sensitivity of segments of ileum to carbachol and a marked inhibition o f both true and total cholinesterase. The results indicate that a relationship between the degree of subsensitivity and the extent of cholinesterase inhibition may exist.
