EC50、IC5、LC50、LD50 EC50 - when experiment to death as a biological reaction to poison, but observation to determine a certain impact on the biological poison, such as fish out of balance, deformity, changes in enzyme activity and the algae growth inhibition, commonly used effective ...
程序使用方法 (1)KT50、LC50和LD50(均以LD50 表示):首先是功能选择,输入1选直接回归法,计算 KT50或动物毒理LD50;输入2为加权回归法,计算动 物LD50和杀虫剂的LC50或LD50。然后按照显示提示输 入每组动物数,实验组数(或击倒率观察次数),再输 入剂量值(X值)及反应值(如动物死亡数、昆虫击倒 ...
The calculation of KT50. LC50 and LD50 valus can be simplied through use of a computer. The computer program in BASIC presented in this paper was developed in 1989 and run in SHARP PC-1500 and CASIO FB series computers and IBM PC compatible With this program, the KT50. LC50 and LD50...
Calculation of Carcinogenic Potency from Long-Term Animal Carcinogenesis Experiments Nonparametric procedures are developed for estimating the TD50 and for constructing confidence intervals. These are based on likelihoods which assume that the ... C Sawyer,R Peto,BMC Pike - 《Biometrics》 被引量: 126...
