目的:探讨鸦胆子油乳对人白血病多药耐药K562/VCR细胞株增殖抑制的作用。方法:使用四唑盐（MTT）比色法对经过鸦胆子油乳干预作用后的体外细胞K562/VCR细胞增殖抑制比率进行检测。结果:随着鸦胆子油乳浓度水平的不断升高（125、250、500、750、1 000 mg/L），对K562细胞的抑制比率持续增加，差异有统计学意义（n P<0.05）。随着鸦胆子油乳作用时间的不断增加（24、48、72 h），对K562细胞的抑制比率持续增加，差异有统计学意义（n P<0.05）。随着鸦胆子油乳浓度水平的不断升高（500、750、1 000、1 500、2 000 mg/L），对K562/VCR细胞的抑制比率持续增加，差异有统计学意义（n P<0.05）；随着鸦胆子油乳作用时间的不断增加（24、48、72 h），对K562/VCR细胞的抑制比率持续增加，差异有统计学意义（n P<0.05）。伴随鸦胆子油乳浓度水平的不断升高（空白对照组、鸦胆子油组500、750、1 000、1 500 mg/L），K562/VCR细胞周期当中的Gn 0/Gn 1比率持续升高，S比率及Gn 2/M比值持续降低，差异有统计学意义（n P<0.05）。注射鸦胆子油乳之后，K562/VCR细胞当中的ADM浓度（荧光强度）显著升高（161.4 ± 10.9比95.9 ± 8.1），差异有统计学意义（n P<0.05）。n 结论:鸦胆子油乳能够对多药耐药K562/VCR细胞株增殖产生抑制作用，同时还能够对多药耐药细胞周期的阻滞产生诱导作用；鸦胆子油乳能够增加多药耐药K562/VCR细胞株当中化疗药物的积贮量。“,”Objective:To investigate the inhibitory effect of Brucea javanica oil emulsion on the proliferation of human leukemia multi-drug resistant K562/VCR cell line.Methods:Methyl thiazolyl tetrazolim (MTT) colorimetric method was used to detect the proliferation inhibition rate of K562/VCR cells in vitro after intervention with Brucea javanica oil emulsion.Results:With the increasing concentration of Brucea javanica oil emulsion (125,250,500,750,1 000 mg/L), the inhibition ratio to K562 cells continued to increase (n P<0.05), and with the increasing duration of Brucea javanica oil emulsion(24,48,72 h), the inhibition ratio to K562 cells continued to increase (n P<0.05). With the increasing concentration of Brucea javanica oil emulsion(500,750,1 000,1 500,2 000 mg/L), the inhibition ratio of K562/VCR cells continued to increase (n P<0.05), and with the increasing action time of Brucea javanica oil emulsion (24,48,72 h), the inhibition ratio of K562/VCR cells continued to increase (n P<0.05). With the increasing concentration of Brucea javanica oil emulsion(blank control group , Brucea javanica oil emulsion group for 500,750,1 000,1 500 mg/L), the Gn 0/Gn 1 ratio in K562/VCR cell cycle continued to increase, while the S ratio and Gn 2/M ratio continued to decrease (n P<0.05). After injection of Brucea javanica oil emulsion, ADM concentration (fluorescence intensity) in the cells increased significantly(161.4 ± 10.9 vs. 95.9 ± 8.1)(n P<0.05).n Conclusions:Brucea javanica oil emulsion can inhibit the proliferation of multi-drug resistant K562/VCR cell lines and induce the arrest of multi-drug resistant cell cycle. Brucea javanica oil emulsion increasesd the accumulation of chemotherapeutic agents in multi-drug resistant K562/VCR cell lines.
