在局部照射条件下,定量研究正常组织的辐射损伤及抗放药的辐射防护作用,不仅可以为正确应用抗放药提供依据,而且可以从抗放药对某一种正常组织的辐射防护效价,判断对人整体的辐射防护效价。当前常用的评价药效的血液学指标(如白细胞总数、淋巴细胞染色体畸变率等)虽然重要,但对放疗病人局部分次照射时有的抗放药对上述 Under local irradiation conditions, quantitative study of normal tissue radiation damage and anti-radiation protective effect of radiotherapy, not only can provide the basis for the correct application of anti-lethal drugs, but also from anti-drug on a normal tissue radiation protection potency , To determine the overall radiation protection of people potency. Currently used to evaluate the efficacy of hematology (such as the total number of leukocytes, lymphocyte chromosome aberration rate, etc.), although important, but radiotherapy patients partial irradiation with anti-lethality of the above
