核酸代谢是机体内对射线较敏感的一个重要环节。在急性放射病时,体内一些重要生命物质代谢,尤其是核酸代谢遭到破坏,并导致其他一系列物质代谢的紊乱,从而影响整个细胞代谢过程,造成组织和脏器的功能障碍,成为急性放射损伤重要发病机理之一。因此,机体在受急性外照射时,若能阻断和抑制其代谢紊乱进一步发展,或能修复体内核酸大分子的辐射损伤,并加速核酸的合成代谢等,就成为
Nucleic acid metabolism is an important part of the body’s sensitivity to radiation. In the case of acute radiation sickness, metabolism of some vital substances in the body, especially the destruction of nucleic acid metabolism, leads to the disorder of metabolism of other substances, thereby affecting the metabolism process of the whole cell, resulting in dysfunction of tissues and organs and becoming an acute radiation injury. One of the important pathogenesis. Therefore, when the body is exposed to acute external radiation, if it can block and inhibit the further development of its metabolic disorder, or it can repair the radiation damage of nucleic acid macromolecules in the body, and accelerate the anabolic metabolism of nucleic acids, etc., it becomes
