摘要
目的 :研究活血化瘀复方对人慢性粒细胞白血病细胞株K5 6 2细胞增殖、凋亡的影响 .方法 :通过台盼蓝拒染法活细胞计数 ,绘制细胞生长曲线 .光镜、透射电镜观察细胞形态学变化 .流式细胞检测定量观察细胞凋亡及其与药物的关系 .结果 :活血化瘀复方对K5 6 2细胞生长具有抑制作用 ,并且细胞呈现典型的凋亡形态学改变 .流式细胞检测显示药物血清作用 6h ,K5 6 2细胞即已出现凋亡 ,10 0mL·L-1含药血清组细胞凋亡率较 5 0mL·L-1含药血清组高 (13.4± 1.3) %vs(7.6± 0 .9) % ,P <0 .0 1.结论 :活血化瘀复方具有抑制白血病细胞生长 ,诱导白血病细胞凋亡的作用 ,从而为其临床应用提供了理论依据 .
AIM: To investigate the effects of blood-activating and stasis-eliminating compound on the proliferation and apoptosis of human chronic myelocytic leukemia cell line K562 cells. METHODS: Living cells were counted by trypan-blue excluding and cell growth curve was drawn. Changes of cell morphology were observed by light and transmission electron microscopy. Flow cytometry (FCM) was used to determine cell apoptosis quantitatively. RESULTS: Chinese herbal compound inhibited the proliferation of K562 cells. The apoptosis of K562 cells was confirmed by FCM and typical ultrastructural changes. The apoptosis rate of 100 ml·L -1 drug serum was higher than that of 50 ml·L -1 drug serum (13.4%±1.3% vs 7.6%± 0.9%, P < 0.01). CONCLUSION: Chinese herbal compound can inhibit the proliferation of human chronic myelocytic leukemia cell line K562 cells and induce the apoptosis of K562 cells.
