LD_(50)是 Lethal dose 50%的缩写,它的原意是50%致死量,亦即使实验动物牛数死亡所需的剂量。ED_(50)是 Effectivedose 50%的缩写,它的原意是50%有效量,亦即使实验动物50%出现阳性结果所需的剂量。LD_(50)与 ED_(50)的基本道理相同,所不同者,只是一个用“死亡”做效果的标志,而另一个用动物的其他反应做效果的标志。为简便计,以下只用一个名词——LD_(50)。
LD_ (50) is Lethal dose 50% of the abbreviation, it is intended to 50% lethal dose, even if the number of experimental animals died of cattle dose. ED 50 is an abbreviation for Effectivedose 50%, which is intended to be a 50% effective amount, ie, the dose required for a positive result of 50% in experimental animals. The basic principle of LD_ (50) is the same as that of ED_ (50). The difference is that LD_ (50) is only a sign of using “death” to effect, and the other sign of effect is from other reactions of animals. For simplicity, the following is a single noun --LD_ (50).
