Outline of Final Research Achievements

This study has an aim to maximize efficiency of regenerative medical techniques for radiation emergency by maximizing nutritional components. Four nutritional factors, 1) Marine Crystal Mineral, 2) DietGel, 3) Ketogenic diet, and 4) Elementary liquid diet were orally treated to severely irradiated mice, respectively. Among them, the elementary liquid diet showed improvement in reducing kinetics of body weight loss after 4 days post irradiation and in survival period. Further studies will be conducted at elsewhere to investigate effect of the elementary liquid diet on transplantation efficiency of stem cells and of their function in rescuing severely irradiated mice.
