作者给大鼠以 LD_(50)量的醋酸铵,发现血、脑氨含量以及中毒后的死亡率与中毒后时间有关,并绘制曲线进行了分析:自中毒后五秒钟,血中氨量剧烈增加,以后则下降,随之又上升,20秒时又显著地增高,随之又下降。这种现象过去从未发现。中毒后20—25秒时,脑中氨含量骤然上升,可达10.5微克分子/克脑,此水平一直保持到50秒而不变,但50秒后则又下降,到120秒时可降到6.02微克分子/克脑。
The author of LD_ (50) of the amount of ammonium acetate, found that blood, brain ammonia content and mortality after poisoning and poisoning time, and draw the curve were analyzed: five seconds after poisoning, the amount of ammonia in the blood Increased violently, decreased later, and then increased again significantly higher at 20 seconds, and then decreased again. This phenomenon has never been discovered before. 20-25 seconds after poisoning, the brain suddenly increased ammonia content, up to 10.5 micrograms of molecules / gram brain, this level has been maintained to 50 seconds and unchanged, but after 50 seconds and then dropped to 120 seconds can be reduced to 6.02 micrograms of molecule / gram brain.
