摘要:  目的 验证微量荧光法(MFA)用于恶性疟原虫体外药物敏感性和抗疟药物筛选的适用性。方法 运用MFA测定氯喹、青蒿素、蒿甲醚和咯萘啶等4种常用抗疟药物对体外培养FCC1/HN株恶性疟原虫的敏感性,并对该方法所测得的量效曲线(dose-response curves)及50%有效抑制浓度(IC50)与光学显微镜镜检法所得的结果进行比较。结果 MFA所测定的氯喹、青蒿素、蒿甲醚和咯萘啶的IC50分别为18.79、6.32、3.67和2.00 nmol/L,光学显微镜镜检法的结果分别为19.65、5.82、4.38和2.83nmol/L,两者差异均无统计学意义(P>0.05)。结论 用MFA体外测定恶性疟原虫对抗疟药的敏感性敏感、快速,可用于体外抗疟药物的敏感性测定及抗疟药物筛选。

Abstract: Objective To determine the feasibility of the microfluorimetric assay (MFA) in screening antimalarial drugs. Methods The dose-response curves and effective concentration that resulted in a 50% inhibitory of parasitemia (IC50 ) of chloroquine, artemisinin, artemether and pyronaridine phosphate against Plasmodium falciparum strain FCC1/HN cultured in vitro were tested by microfluorimetric assay (MFA) and compared with those determined by microscopy-based assay. Results The IC50 of chloroquine, artemisinin, artemether and pyronaridine phosphate were 18.79, 6.32, 3.67 and 2.00 nmol/L by MFA and the IC50 of which were 19.65, 5.82, 4.38 and 2.83 nmol/L by microscopy-based technique respectively. The results from both techniques were similar or identical (P>0.05). Conclusion The microfluorimetric assay (MFA) is sensitive, rapid, easily interpreted and would be useful for testing the sensitivity of Plasmodium falciparum to antimalarials and for screening drugs.
