Abstract

1. Changes of corticosterone level in the plasma and tyrosine aminotransferase (TAT) in the liver following treated and untreated dichlorvos poisoning in rats were studied. 2. Corticosterone level during untreated poisoning was increased only. During treated dichlorvos poisoning and following antidotal treatment without poisoning, no significant changes of corticosterone level were observed. 3. Expressive increase of TAT activity in the third and 24th hour of untreated poisoning was demonstrated. Following treatment of dichlorvos poisoning with atropine, obidoxime and diazepam, the delayed and lower increase of TAT activity was observed. Following antidotal treatment without poisoning, no significant changes of TAT activity except its decrease in the third hour were demonstrated. 4. The treatment of dichlorvos poisoning practically eliminate stressogenic effects of dichlorvos. Moreover, the markers could be used for evaluating the effects of antidotes against organophosphate poisoning.

敌敌畏致应激效应的处理。
1. 研究了敌敌畏中毒前后大鼠血浆皮质酮水平和肝脏酪氨酸氨基转移酶(TAT)的变化。2. 在未经治疗的中毒期间,皮质酮水平仅升高。在敌敌畏中毒治疗期间和未中毒解毒剂治疗后,皮质酮水平无明显变化。3.TAT活性在未处理中毒后第3、24小时显著升高。在用阿托品、奥比肟和地西泮治疗敌敌畏中毒后,观察到TAT活性的延迟和较低的升高。在未中毒的解毒剂治疗后,除第3小时TAT活性下降外,未见明显变化。4. 敌敌畏中毒的治疗实际上消除了敌敌畏的应激性影响。此外,该标记物还可用于评价解毒剂对有机磷中毒的作用。
