| Outline of Final Research Achievements |
To investigate the scientific basis of risk leading to cardiovascular disorders due to radiation exposure, we used the intravital microscope system, which is possible to observe the microcirculatory dynamics of the same region for long time.
We clarified the influence on the circulation index. In addition, oxidative stress caused by radiation exposure was visualized by detecting oxidative stress response by luminescence imaging, and the relationship between oxidative stress response generation site and circulatory dynamics was examined.
