Enhancement Effect of Microbubble-Enhanced Ultrasound in Microwave Ablation in Rabbit VX2 Liver Tumors

Figure 6

Identification and quantification of TUNEL (terminal deoxynucleotidyl transferase dUTP nick-end labeling) positive VX2 liver tumor cells. (a–d) Representative images from the control group, the MEUS group, the MWA group, and the MEUS + MWA group. TheVX2 liver tumor cells are stained with TUNEL (green) and DAPI (4′,6-diamidino-2-phenylindole, dihydrochloride) (blue), indicating a higher level of apoptosis in the treated tumors relative to the control tumors. The apoptotic rate in the MEUS + MWA group was significantly different from the control group (). There was a significant difference between the apoptotic rates of the MEUS + MWA group and the other two treatment groups, respectively ( and ).
