根据毒物或废水试验浓度和受试动物的死亡率用半对数纸作图,在死亡率50%处划一垂线至浓度坐标,即可求出不同暴露时间内的LC50。增加试验次数和适当缩小试验浓度间距,可提高LC50值的精确度。运用图解法(Litchfield and Wilcoxon法),可计算出LC50值的可信限,从而估算出与受试动物同类的动物死亡50%的毒物浓度范围。 同样...

药物半数致死量LD50的测定实验 实验方法原理 药物半数致死量LD50是指药物急性毒性实验中,当动物死亡率为50%时的单次给药剂量,单位通常为mg/kg。例如,当某药物给予400mg剂量时,可致使一半家兔(体重约为4kg)死亡,则其LD50值为100mg/kg。LD50值通常反映药物急性毒性的大小。药物的急性毒性、慢性毒性实验同属于一般毒...
