Research Abstract

Irradiation in radiation therapy or bone marrow transplantation is known to cause damage to normal tissues. Although some substances are reported to suppress the damage(=radioprotectors), most of them have strong side effects and are not applicable in vivo. However, ascorbic acid and AHCC (Active Hexose Correlated Compound) are known as safe radioprotectors with antioxidant activity. While examining some radioprotectors using mice, we found that ascorbic acid and AHCC suppress fibrosis of lung and kidney caused by irradiation.
