在辐射防护药物研究中,如何推断动物实验有效的药物对人体急性放射损伤的防护是否有效,至今是一个尚未解决的课题。曾经进行了多种途径的探讨,如观察药物对肿瘤放疗病人的放射损伤的保护,用人的离体细胞培养试验观察药物对细胞的直接保护作用等,都从不同的侧面说明了一定的问题。但仍不够完善。有必要开展更多方面的工作,为抗放药物的人体效价推理提供更为充分的 In the study of radiation protection drugs, how to deduce whether effective anti-acute drugs in animals are effective in protecting human from acute radiation injury has so far been an unresolved issue. There have been a variety of ways to explore, such as the observation of drug radiotherapy for patients with radiotherapy of radiation damage, the use of human in vitro cell culture experiments to observe the direct drug protection of cells, all from a different side illustrates the problem. But still not perfect. It is necessary to carry out more work in order to provide a more adequate
