| 摘 要： | 研究不同分子质量的软骨多糖对慢性髓系红白血病K562细胞的增殖抑制作用。用不同浓度的酒精对软骨提取物进行分级沉淀，得到不同分子质量的软骨多糖，并用聚丙烯酰胺凝胶电泳（SDS-PAGE）检测所得软骨多糖的纯度及分子质量；采用噻唑蓝（MTF）比色法测定细胞的增殖活性；用琼脂糖凝胶电泳法检测DNA电泳特征。结果显示，短链软骨多糖（分子质量约为30ku）对K562细胞具有明显的增殖抑制作用，这种抑制作用呈现明显的时间依赖性，且琼脂糖凝胶电泳出现明显的DNA梯状条带。

| Abstract: | The aim of this paper was to study the effect of the proliferation of chronic myegenous leukemia ( K562) treated by different molecular weight cartilage polysaccharide( sc-PS). Cartilage extract was precipitated by ethanol with different concentration. Different molecular weight polysaccharide was collected. Then concentration and molecular weight of them were studied by SDS-PAGE; MTT method was used to test the proliferation of cells treated by sc-PS; Agarose gel electro-phoresis was used to detect the characteristic of DNA; The results indicated that the growth of K562 cells was inhibited obviously by sc-PS, which in a dose-dependent, DNA ladder could be observed apparently in agarose gel electrophoresis. |
