用清洁级ICR小鼠为实验动物,探讨芜菁块根汁对~(60)Co-γ射线辐照损伤的防护和修复效应。测定血象、白细胞分类计数、脾指数、胸腺指数和小鼠PCE的微核试验等方法。结果表明:辐照前给芜菁汁组、辐照后给芜菁汁组和连续给芜菁汁组分别使小鼠体重、免疫器官指数、血象、PCE微核率等明显高于~(60)Co-γ辐照组,其中免疫器官指数、红细胞、白细胞和血小板、PCE微核率等数据与~(60)Co-γ辐照组的差异极为显著(P<0.001)。说明芜菁块根汁对小鼠机体造血和免疫系统受到电离辐射损伤时不仅具有明显的防护作用,而且对辐射损伤具有一定的修复作用。
Using clean-grade ICR mice as experimental animals, the protective and repairing effects of root juice of Brassica rapa on 60Co-γ-ray irradiation were investigated. Determination of blood, leukocyte count, spleen index, thymus index and micronucleus test of mouse PCE and other methods. The results showed that the weight, immune organ index, blood count, and micronucleus rate of PCE in the turnip juice group before irradiation, the turnip juice group and the turnip juice group were significantly higher than the ~(60). ) Co-γ irradiation group, in which the immune organ index, red blood cells, white blood cells and platelets, PCE micronucleus rate data and the 60 Co-γ irradiation group, the difference was extremely significant (P <0.001). The results showed that the root juice of the root tuber not only has obvious protective effect on the hematopoietic and immune system of mice when exposed to ionizing radiation, but also has a certain repairing effect on radiation damage.
