化学药物防护辐射损伤已经广泛研究,但防护药物或合并用药大都具有毒性。维生素 C 曾经用于治疗放射病,然应用大剂量维生素 C 以防护辐射损伤迄今未见研究。不同的照射剂量对肾上腺皮质维生素 C 含量的影响早已作测定。如致死剂量照射后肾上腺皮质维生素 C 含量第一次下降发生于照射后2～3小时,然后于24小时回升至最初水平,再次下降发生于72小时。而亚致死剂量照射时,再次下降
Chemical Radiation Protection Radiation damage has been extensively studied, but protective drugs or combination drugs are mostly toxic. Vitamin C has been used to treat radiation sickness, but the application of large doses of vitamin C to protect against radiation damage so far no study. Different doses of radiation on adrenocorticotropic vitamin C content has long been determined. After a lethal dose of irradiation, the first decrease in adrenal cortical vitamin C content occurred 2 to 3 hours after irradiation, then returned to its original level at 24 hours and again to 72 hours. Sub-lethal dose irradiation, once again decreased
