目的:探讨不同条件下低强度中频超声对宫颈癌细胞生长的影响.方法:以不同强度及时间的低强度中频超卢作用于人宫颈癌CaSki细胞,用MTT法检测细胞死亡数量,找出细胞抑制率的总体趋势.结果:不同条件下的低强度中频超声幅照各组间细胞抑制率与对照组相比有统计学差异,且各组间也存在统计学差异.结论:单纯低强度中频超声对人宫颈癌Ca Ski细胞有较强杀伤作用,且与幅照的时间和强度呈明显相关性.
目的:探討不同條件下低彊度中頻超聲對宮頸癌細胞生長的影響.方法:以不同彊度及時間的低彊度中頻超盧作用于人宮頸癌CaSki細胞,用MTT法檢測細胞死亡數量,找齣細胞抑製率的總體趨勢.結果:不同條件下的低彊度中頻超聲幅照各組間細胞抑製率與對照組相比有統計學差異,且各組間也存在統計學差異.結論:單純低彊度中頻超聲對人宮頸癌Ca Ski細胞有較彊殺傷作用,且與幅照的時間和彊度呈明顯相關性.

Objective: To investigate the effect of low-intensity ultrasound on the growth of human cervical cancer Ca Ski cells. Methods: The human cervical cancer Ca Ski cells were irradiated by low- intensity ultrasound with different intensity and time. The intensity of uhrasound(1.7MHz)was 0.65 W/cm~2~ and 0.8W/cm~2,respectively. The exposure time was 10, 20, 30, 40, 50 and 60 s respectively:Ca Ski cells were incubated in 24 well cuhure plates for 24 hours after sonication and Cytotoxicity, was tested by MTT ashy. Results: Cytotoxicity of ultrasound radiation on Ca Ski cells in the experimental groups was significantly higher than that in the controls (P<0.05). Conclusion: Ultrasound exposure can effectively inhibit the growth of Ca Ski cells. The effect is relevant to the intensity and exposure time of ultrasound radiation.
