有关电离辐射对氨基酸代谢的影响,大多数报道是急性的,照射时间短。而有关慢性照射的报道甚少。电离辐射对蛋白质及氨基酸分子起变性破坏作用,放射损伤时,蛋白质代谢障碍是明显的,合成受阻,分解增强,尿中排出的氨基酸在质和量方面均有显著改变,某些重要器官中氨基酸含量有减少趋势,血清(或血浆)中氨基酸含量发生变化,这些变化与放射病严重程度有联系营养不良时,对放射线的敏感性增高,而合理的膳食组成能减轻放射损伤程度,某些氨
The impact of ionizing radiation on amino acid metabolism, most reports are acute, irradiation time is short. There are few reports about chronic irradiation. Ionizing radiation has a degenerative effect on proteins and amino acids. During radiation injury, protein metabolism disorders are obvious. The synthesis is blocked and the decomposition is enhanced. The amino acids excreted in the urine have significant changes both in quantity and in quality. In some important organs, amino acids The content of serum amino acids in serum (or plasma) changes, these changes associated with the severity of radiation sickness, malnutrition, increased sensitivity to radiation, and a reasonable diet can reduce the degree of radiation damage, some ammonia
