The Reversal by Oximes of Neuromuscular Block Produced by Anticholinesterases

The reactivation by hydroxamic acids //0 (R-C-NHOH) of acetylcholinesterase (ChE) in- hibited by organo-phosphorus anticholinesterases has been described by Wilson and Meislich (1953), Wilson and Ginsburg (1955) and Jandorf, Crowell, and Levin (1955).It has recently been found that the oximes ( R,>C-=NOH) are more potent reacti- vators of inhibited ChE than the hydroxamic acids and, like the latter, also react with the inhibitor (Childs, Davies, Green, and Rutland, 1955).
