声动力效应抑制卵巢癌细胞的体外实验

In vitro effects of sonodynamic management on inhibition of ovarian cancer cells

目的研究超声激活血卟啉对卵巢癌细胞抑制的体外效应。方法应用一定强度的超声激活血卟啉,采用四甲基偶氮唑蓝法、克隆形成率方法检测抑制卵巢癌细胞的作用,并用显微镜观察处理后细胞形态的变化,流式细胞术检测细胞凋亡。结果超声激活血卟啉对抑制细胞生长有明显作用(P<0.05),且随着血卟啉浓度的升高,抑制作用明显增强(P<0.05)。同时,超声激活血卟啉的效应与超声辐照时间有关。结论声动力处理抑制细胞生长作用明显,并可以诱导凋亡。

Objective To study the in vitro effects of sonodynamic management on human ovarian cancer cell line HRA. Methods Hematoporphyrin was selected as a sonosensitizer and ultrasound with certain intensity was used to activate hematoporphyrin.Then MTT assay and clony-forming efficiency assay were applied to determine the growth inhibitory effects of ovarian cancer cells. Electron microscope was applied to detect the morphological changes of the cells. Cell apoptosis was analyzed using flow cytometry. Results Hematoporphyrin had no significant inhibitory effects on the cells. However, when hematoporphyrin was used before ultrasound,it could enhance the killing effects of ultrasound(P<(0.05)).With the increasing concentration of hematoporphyrin and time of ultrasound treatment, the inhibitory effects increased(P<(0.05)). Apoptosis was found by flow cytometry and electron microscope. Conclusions(Sonodynamic) management could significantly suppress the proliferation and induce apoptosis in ovarian cancer cells.
