| Outline of Final Research Achievements |
The different biological effect of radiation exposure is induced by different radiation doses. From this viewpoint, the rapid, accurate dose estimation is anticipated when radiation accident is occurred. Until now, counting chromosome aberration in peripheral blood lymphocyte is the most accurate method for evaluating exposed dose, but this method is time consuming and requires expert skills. Our final goal is to establish rapid, high-throughput radiation bio-dosimetry/radiation risk assessment method using noninvasive specimen materials. The glycosylation status of mouse urine Adipsin protein was modulated for 8 to 48 h after 0.25 to 6 Gy of radiation exposure. The establishment of radiation bio-dosimetry method using the protein glycosylation status will be expected in the future.
