摘要: 本文报告红细胞浓度、起始原虫感染率以及培养时间等因素,对体外测定恶性疟原虫氯喹敏感性的影响。结果表明,使原虫减少50%(或95%)所需氯喹的浓度(SC_(50)或SC_(95)),与所观察的红细胞浓度(1.25~10%)呈正相关(γ值分别为0.94和0.92),与起始原虫感染率(0.5~4%)也呈正相关(γ值分别为0.95和0.99)。培养时间以48小时较适宜。

Abstract: The influence of some factors including the erythrocyte concentration, the starting rate of parasitemia and the cultivation time on the ire vitro determination of chloroquine sensitivity of Plasmodium falciparum were studied. The results showed that the chloroquine concentration required to produce 50% or 95% reduction of the parasitemia (SC50 or SC95) was positively related to the observed erythrocyte concentrations (1.25-10%), their r values being 0.94 and 0.92, respectively, and also related to the starting rate of parasitemia (0.5-4%), their r values being 0.95 and 0.99, respectively. 48-hour cultivation was considered to be suitable.
