摘 要:目的:研究菱灵颗粒有效成分—化合物Ⅰ在体外对Hela细胞的作用及其作用机制。方法:采用四甲基偶氮唑盐(MTT)还原法检测化合物Ⅰ对肿瘤生长抑制作用,应用光学显微镜、透射电子显微镜观察细胞形态,流式细胞仪检测细胞周期及细胞凋亡情况。结果:化合物Ⅰ对人宫颈癌细胞生长具有明显的抑制作用及诱导细胞凋亡作用,且这种作用有剂量依赖关系,化合物Ⅰ25、12.5、6.25mg/L剂量组30h抑瘤率为52.04%、34.44%、23.72%,100、50、25、12.5、6.25、3.125mg/L剂量组30h抑瘤率显著正相关,相关系数r=0.9860(p<0.01),IC50值为10.9mg/L。透射电子显微镜对化合物Ⅰ25、12.5、6.25mg/L剂量组受试细胞观察,均出现不同程度细胞凋亡现象,细胞核明显皱缩、染色质趋边凝聚、线粒体空化等特征。流式细胞仪检测发现凋亡峰。结论:化合物Ⅰ对Hela细胞增殖抑制作用明显并且有诱导细胞凋亡作用。Objective : To investigate the effects of Compound Ⅰ abstracted from ling ling pellet on human Hela cell so as to explore its mechanism. Methods: Growth inhibition was assayed with MTr. The morphological changes of Hela cells induced by compound Ⅰ were observed with transmission electronic microscope and phase contrast microscope. Cell division cycle distribution and apoptosis affected by compound Ⅰ was determined with flow cytometry. Results: The growth of human Hela cells is significantly inhibited which display strong in a dose and time-dependant manners against and induced apoptosis of Hela cells. Hela cell with estimated IC50 values of 10.9mg/L, concentration of 25, 12.5, 6.25mg/L inhabiting rate is 52.04%, 34.44%, 23.72% after 30h of treatment with compound I. Concentration of 100, 50, 25, 12.5, 6.25, 3.125mg/L inhabiting rate is good correlation (r=0.9860, p 〈 0.01). Expose of Hela cells to 25, 12.5, 6.25mg/L of compound Ⅰ induced nuclear shrinkage, chromatin condensation and margination against nuclear envelope as seen in apoptotic cells. The follow cytometry profile revealed that treatment with different Concentrations compound Ⅰ inducted apoptosis. Conclusion: Growth of human Hela cells was significantly inhibitory and apoptosis may play an important role in the anti-tumor effect of active compound Ⅰ.
