Sonication could obviously suppress proliferation of COC1 cells surviving ultrasound exposure; The absorbance value(A570) of MTT significantly decreased at 12 h, 24 h, 36 h and 48 h after sonication as compared to control group;

• 低频脉冲聚焦超声可明显抑制存活卵巢癌COC1细胞株的增殖,辐照后12h、24h、36h和48h,COC1细胞MTT光吸收值与对照组相比显著降低;
