To develop an in vitro method for the assessment of drug response in P. falciparum to pyronaridine/sulfadoxine/pyrimethamine (PND/S/P).
The PND/S/P microtest plate was designed, Rieckmann in vitro microtest(WHO standard kit) was used to test the sensitivity of P falciparum in continuous culture (FCC1/HN strain), and the data obtained were analyzed using a computer programme. Fractional inhibitory concentration (FIC) was calculated to test the possible synergy between PND and S/P.
The effect of the PND/S/P plates was fairly stable and the ED50 values of pyronaridine, sulfadoxine and pyrimethamine were 0.11, 215.12 and 2.9 pmol, respectively. The FIC obtained confirmed the synergism between PND and S/P.
The in vitro method can be used to assess the sensitivity of P. falciparum to pyronaridine/sulfadoxine/pyrimethamine.
建立一种体外评估恶性疟原虫对咯萘啶/磺胺多辛/乙胺嘧啶(PND/S/P)药物反应的方法。
设计PND/S/P微量测试板,采用里克曼体外微量测试法(WHO标准试剂盒)检测连续培养的恶性疟原虫(FCC1/HN株)的敏感性,并使用计算机程序分析所得数据。计算分数抑制浓度(FIC)以检测PND与S/P之间可能的协同作用。
PND/S/P板的效果相当稳定,咯萘啶、磺胺多辛和乙胺嘧啶的半数有效剂量(ED50)值分别为0.11、215.12和2.9皮摩尔。获得的FIC证实了PND与S/P之间的协同作用。
该体外方法可用于评估恶性疟原虫对咯萘啶/磺胺多辛/乙胺嘧啶的敏感性。
