| Outline of Final Research Achievements |
The purpose of this study is to clarify the sensitizing effect of irradiation-induced apoptosis after ultrasound exposure in the presence of microbubbles. Mouse sequemous cell carcinoma cell was irradiated right after the ultrasonic exposure with microbubbles resulted in sensitizing effect of 1.1. After considering optimal irradiation timing in the light of the effect of cell cycle variation of ultrasound exposure, it was suggested that 9 hours after the ultrasound exposure was suitable. However, the sensitizing effect of irradiation-induced apoptosis remained 1.1. Further study is needed using 3-dimensional cell culture system.
