摘要: 旨在研究福安泰(FAT)对人类白血病K562/A02 细胞多药耐药的逆转作用。用噻唑蓝(MTT)法检测药物敏感性及FAT 对细胞耐药性的影响;用流式细胞仪检测细胞内罗丹明123(Rhodamine 123)的含量;采用生物化学DTNB 法测定细胞内GSH 含量。结果显示,低浓度FAT 对K562/A02 细胞和K562 细胞均无直接细胞毒作用。FAT 可以降低阿霉素对K562/A02 细胞的IC50 值,对K562 细胞没有明显影响。FAT 可增加K562/A02 细胞内罗丹明123(Rhodamine 123)的含量。K562/A02 细胞内GSH 含量高于K562 细胞内GSH 含量,FAT 可降低K562/A02 细胞内GSH 的含量。表明FAT 降低K562/A02 细胞内GSH 的含量是FAT 逆转MDR 的机制之一。

Abstract: This test was designed to study the effects of FAT on multidrug resistance(MDR)in human leukemia K562/A02 cells. MTT method was used to observe the drug sensitivity and the effect of FAT on the drug resistance; Flow cytometer was used to measure the intracellular drug accumulation; Cellular GSH concentration was examined by biochemical analyses with DTNB. Results showed that FAT did not exhibit an inhibitory activity to proliferation in K562 cell line and K562/A02 cell line. FAT decreased IC50 of ADM in K562/A02 cell line. And it had no remarkable effect on K562 cell line. FAT increased the intracellular Rho-123 concentration. Cellular GSH concentration in K562/ A02 cell line was higher than thatin K562 cell line. FAT decreased cellular GSH concentration in K562/A02 cell line. One of the mechanisms of multidrug resistance reversal by FAT was decrease of cellular GSH concentration in K562/A02 cell line.
