ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of the Compound Fritillaria thunbergii Miq Particles (CFMP) to the sub-cellular accumulation ability and inducing the apoptosis of K562/A02 cells, explore the mechanism of the CFMP reserve the multi-drug resistance of K562/A02 cells.</p><p><b>METHODS</b>Forty Wistar male rats were divided into the blank-serum group, the adriamycin (ADR) containing serum group, the CFMP high dose [8 g/ (kg x d)] group, the CFMP medium dose [4 g/(kg x d)] and the CFMP low dose [2 g/(kg x d)] group. The effects of different time of drug contained serum on sub-cellular accumulation of ADR and Rh123 were quantitative detected by flow cytometry. Cells apoptosis induced by different concentrations of CFMP contained serum were detected by flow cytometry with Annexin-V/PI staining method.</p><p><b>RESULTS</b>Different concentrations of CFMP contained serum can inhibit the descend trend of the ADR and Rh123 fluorescence accumulation curve of K562/A02 cells with dose-dependence. The high-dose group showed superior inhibition than the other. Annexin-V/PI staining method exhibited that the rate of apoptosis of K562/A02 cells in blank-serum group was 1.40%. Different concentrations of CFMP contained serum induced the apoptosis of K562/A02 cells showed a dose-dependent manner, that is medium dose group presented 24.60% apoptosis, high dose group presented 11.21% apoptosis, and low dose group presented 5.71% apoptosis.</p><p><b>CONCLUSION</b>CFMP can inhibit the descend trend of the ADR and Rh123 fluorescence accumulation curve of K562/A02 cells, induce the apoptosis of K562/A02 cells to achieve the reverse intention of multi-drug resistance.</p>
