The effects of monoisonitrosoacetone (MINA), diacetylmonoxime (DAM) and pyridine-2-aldoxime methiodide (P2AM) upon the cholinesterase of sarin poisoned rats have been studied. Monoisonitrosoacetone and diacetylmonoxime given before sarin protected blood and brain cholinesterase from inhibition. Monoisonitrosoacetone given after the appearance of signs of poisoning caused a rapid reactivation of brain cholinesterase. Diacetylmonoxime, at an equimolar dose, produced only a slight increase in enzyme activity, and pyridine-2-aldoxime methiodide, the best reactivator in vitro, reactivated blood but not brain cholinesterase. There is a relationship between protection and reactivation of brain cholinesterase and prevention and alleviation of signs of poisoning.
研究了单异亚硝基丙酮(MINA)、双乙酰一肟(DAM)和吡啶 -2-醛肟甲基碘(P2AM)对沙林中毒大鼠胆碱酯酶的影响。在沙林之前给予单异亚硝基丙酮和双乙酰一肟可保护血液和脑胆碱酯酶免受抑制。中毒迹象出现后给予单异亚硝基丙酮可使脑胆碱酯酶迅速重新活化。双乙酰一肟在等摩尔剂量时仅使酶活性略有增加,而体外最佳重新活化剂吡啶 -2-醛肟甲基碘可使血液胆碱酯酶重新活化,但不能使脑胆碱酯酶重新活化。脑胆碱酯酶的保护和重新活化与中毒迹象的预防和减轻之间存在关联。
