本实验测定了正常小鼠及~(60)Co γ线6、10、15Gy照射后不同时间小鼠血清唾液酸含量,实验表明,血清唾液酸含量的升高,与照射剂量有一定的关系,小剂量照射时变化不明显,大剂量照射病情严重时,唾液酸含量明显升高,在一定程度上可以反映电离辐射对细胞的损伤程度,本方法用血量少,操作简便,稳定可靠,有可能作为辐射损伤病情的辅助参考,尚须进一步加以探索. This experiment measured the serum and sialic acid levels of mice at different times after exposure to 6, 10 and 15 Gy of normal mice and ~ (60) Co γ-rays. The experimental results show that the serum sialic acid increased with the dose, Small doses of irradiation did not change significantly, high-dose irradiation in serious condition, significantly increased sialic acid content, to some extent, ionizing radiation can reflect the degree of cell damage, the method with less blood, simple, reliable, there It may serve as a supplementary reference for the condition of radiation injury, which needs to be further explored.
