摘要: 背景与目的: 研究中药香加皮水提取物(cortex periplocae extract,CPE) 诱导体外培养人红白血病细胞株K562分化的作用。 材料与方法: 观察人红白血病细胞株K562与CPE体外共培养时的形态学变化;同时采用比色法检测不同浓度CPE诱导人红白血病细胞株K562产生Hb含量的变化。 结果: 与阴性对照相比,CPE可以诱导K562细胞发生坏死的形态学变化。与CPE共培养后K562细胞株Hb的产生明显减少。 结论: CPE 对K562肿瘤细胞只具有杀伤作用而不能诱导K562肿瘤细胞的分化。

Abstract: BACKGROUND AND AIM: To investigate the effect of cortex periplocae extract (CPE) on the differentiation of tumor cells K562 in vitro. MATERIALS AND METHODS: We examined the morphological changes of K562 cells after cultured with CPE; and investigated the induction effect of CPE on the production of Hb from K562 cells by using colorimetry. RESULTS: K562 cells morphology were destroyed by CPE. CPE also markedly reduced the production of Hb from K562 cells. CONCLUSION: CPE could kill K562 cells to some extent, but could not induce the differentiation of K562 cells.
