前一工作表明,无论是经1000伦γ射线照射的成年大鼠,或者是经过840—900伦γ射线一次全身照射后存活36—68天的“恢复大鼠”再经900伦γ射线一次全身照射,动物在受照射后存活时间的长短与血浆中的白蛋白比值密切相关,也与α-球蛋白的比值密切相关,即血浆白蛋白比值高的动物较低的动物对致电离辐射感受性低,相反血浆中α-球蛋白比值高的动物较低的动物对致电离辐射的感受性高。 本实验进一步探讨大鼠对致电离辐射感受性与品种,性别、年龄不同的动物血浆白蛋白组成部分比值的关系。
The previous work showed that both the adult rat irradiated with 1000 nm gamma rays or the “restored rat” survived 36-68 days after a single whole body irradiation with 840-900 nm gamma rays and then once again received whole body irradiation with 900 nm gamma rays Irradiation, the survival time of animals after irradiation is closely related to the ratio of albumin in plasma and also closely related to the ratio of α-globulin, ie, animals with lower plasma albumin ratio have lower sensitivity to ionizing radiation In contrast, animals with lower a-globin ratios in plasma had lower susceptibility to ionizing radiation. This experiment further explores the relationship between the sensitivity of rats to ionizing radiation susceptibility and breed, sex, age, animal plasma albumin ratio.
