本文报告使用肿瘤免疫增强剂多抗甲素进行预防和抵抗放射损伤的动物试验,结果表明,多抗甲素有预防和抵抗小白鼠全身致死性放射损伤的的作用,以照射前用药效果最佳,照射前后都用药和照射后再用药亦具有抵抗放射损害之效果。因此,我们认为此药不仅对肿瘤的治疗,而且对于和平利用原子能和对核辐射损伤的预防和治疗都有重要意义。 This article reports on the use of tumor immunopotentiator polyclonal A to prevent and resist radiation damage in animal experiments. The results show that poly A has the effect of preventing and resisting systemic lethal radiation injury in mice, and the best effect is to use before irradiation. The use of drugs before and after irradiation and irradiation after irradiation also have the effect of resisting radiation damage. Therefore, we believe that this drug is not only for the treatment of tumors, but also for the peaceful use of atomic energy and for the prevention and treatment of nuclear radiation damage is of great significance.
