辐射增敏不仅是放射生物学研究内容之一,而且在肿瘤的放射治疗中有着重要作用。辐射增敏剂能增加射线对肿瘤组织,特别是占10%左右的乏氧细胞的辐射敏感性,因此这项研究在世界各国尤其是英、美等国十分活跃。本文主要介绍开展辐射增敏工作较早的英国研究状况。 Radiation sensitization is not only one of the contents of radiobiological research, but also plays an important role in the radiotherapy of tumors. Radiation sensitizers can increase the radiosensitivity of radiation to tumor tissue, especially about 10% of hypoxic cells. Therefore, this research is very active in countries all over the world, especially the United Kingdom and the United States. This article mainly introduces the UK research status of conducting radiation sensitization earlier.
