The surviving fraction (SF) of Chinese hamster cells and HeLa cells after treatment with a range of Adriamycin concentrations and exposure times was determined. The cytostatic effect was proportional to the product of extracellular drug concentration (c) and exposure time (t) according to the equation: SF=e-ktc. By determining the intracellular drug concentration at various exposures, it could be shown that absorbed dose is not proportional to exposure dose.
测定了中国仓鼠细胞和HeLa细胞在一系列阿霉素浓度和暴露时间处理后的存活分数(SF)。根据公式:SF = e-ktc,细胞生长抑制作用与细胞外药物浓度(c)和暴露时间(t)的乘积成正比。通过测定不同暴露时间下的细胞内药物浓度,结果表明吸收剂量与暴露剂量不成正比。
