| Outline of Final Research Achievements |
In this study, the sonodynamically induced antitumor effect of hydroxyl functionalized carbon nanotubes (OH-CNT) was investigated. Sonodynamically induced antitumor effects of OH-CNT by focused ultrasound were investigated using isolated sarcoma 180 cells and mice bearing ectopically-implanted colon 26 carcinoma. Cell damage induced by ultrasonic exposure was enhanced by five-fold in the presence of 80 uM OH-CNT. The combined treatment of ultrasound and OH-CNT suppressed the growth of the implanted colon 26 carcinoma. Histidine, a reactive oxygen scavenger, significantly reduced cell damage caused by ultrasonic exposure in the presence of CNT OH-CNT. These results suggest that singlet oxygen is likely to be involved in the ultrasonically induced cell damage enhanced by CNT.
