Plasma-Katecholamin-Verlauf bei Alkylphosphat-Intoxikationen und deren Therapie

Abstract

In connection with the "endogenous acetylcholine-poisoning" due to organophosphorous compounds beside the clinical important muscarinic and nicotinic symptoms an activation of the sympathetic nervous system (adrenal medulla, sympathetic ganglia) is expected. Therefore a kinetic profile of norepinephrine and epinephrine in the plasma of two patients with severe parathion-poisonings was taken up through the whole period of the intensive-medical treatment. The method used was HPLC with electrochemical detection. The parathion-concentration of the same plasma samples were measured, too. The result were individual different courses with periodically appearing, markedly increased plasma catecholamine values. A direct correlation of catecholamines with the parathion-concentration was not recognizable. A possible influence of the atropine-treatment as well as of stress-factors is discussed but estimated as not responsible for the observed peaks.

L-lactate reducesin vitro the inhibition of butyrylcholinesterase (bche) by paraoxon (e 600)

“…7 Their inhibition causes endogenous ACh poisoning with parasympathetic over-stimulation and additional catecholamine release by the adrenal glands. 7,8 Oximes are the only enzyme reactivators clinically available. The serendipitous observation that POX solutions in lactated Ringer show a yellowish discoloration, led us to the hypothesis that lactate (lactic acid) might interact with POX and, as such, attenuate the POX effects.…”
