七十年代以来,辐射增敏的研究业已引起人们极大重视。在这次国际大会上,有关辐射增敏的内容较多,其广度与深度都超过前几届国际会议上交流的内容。本文主要根据有关邀请报告、专题讨论报告、分组交流和专题墙报内容整理而成。一、氧传递修饰剂通过改变氧的传递以提高肿瘤细胞对射线的反应,目前采用两种方法:一是直接输入红细胞,使肿瘤组织中靶细胞的氧供得到改善;另一种是用钙通道阻断剂,增加血流的方法。 1.血管活性剂:有作用于血管壁平滑肌的肼苯哒嗪和钙通道阻断剂。关于肼苯哒 Since the 1970s, research on radiation sensitization has drawn great attention. At this international conference, there is more information on radiation sensitization, both in terms of breadth and depth than those exchanged at previous international conferences. This article is mainly based on the invitation of the report, seminar reports, group exchanges and thematic wall newspaper content from. First, the oxygen transfer modifier by changing the oxygen delivery to improve the response of tumor cells to radiation, the current two methods: First, direct input of red blood cells, so that tumor target oxygen in the target cells to be improved; the other is the use of calcium Channel blockers, methods of increasing blood flow. 1. Vasoactive agents: There are hydralazine and calcium channel blockers acting on the vascular smooth muscle. About hydralazine
