[Changes in the electromyographic potentials in cats poisoned with superlethal doses of phosdrin and treated with doline].

The authors carried out studies on 10 cats, anesthetized by urethane, under atropine protection and under the conditions of artificial respiration and examined the influence of therapeutic antidote of phosphorganic pesticides-Doline on the induced eletromyographic activity during total neuro-muscular block, induced by superlethal doses of phosphadrine. It was established that superlethal doses of phosphadrine induced total block of electropotentials in neuro-muscular conduction of the peripheral musculature, which was removed immediately after venous and muscular administration of the antidote Doline.

[Electrophysiologic shifts in the functional antagonism between phosphororganic pesticides and their antidotes].

The authors carried out studies on 18 nonanesthetised and anesthetised cats under the conditions of complete imobilization with tricuran and under artificial respiration and examined the temporary consequence of the effects on the spontaneous and induced cerebral activity after poisoning with lethal doses of phosdrine and treatment with Doline, which is the therapeutic antidote of phosphorganic pesticides. The authors established that after lethal poisoning with phosdrin the secondary induced cerebral hypoxia enhanced deepening of the disintegration in the intercerebral interrelationships, which caused the appearence of epileptiform activity. The antidote Doline within 1-2 minutes, after its muscular administration abolished effectively the generalized epileptic seizure and repaired quickly the electrophysiological indices-peculiar for the normal EEG.
