Sonication could obviously suppress proliferation of COC1 cells surviving ultrasound exposure. The absorbance value(A 570 )of MTT decreased significantly at 12h,24h,36h and 48h after sonication as compared with control group.

• 超声可明显抑制存活卵巢癌COC1细胞的增殖 ,辐照后 12h、2 4h、36h、4 8h ,COC1细胞MTT光吸收值与对照组相比显著降低 ;
