摘要
用 KM小鼠作动物整体试验 ,研究芜菁叶汁对 60 Co- γ射线照射损伤的防护和修复效应 .测定了血象、白细胞分类计数、脾指数、胸腺指数和小鼠骨髓嗜多染红细胞 (PCE)的微核试验等方法 .结果辐照前给叶汁组、辐照后给叶汁组和连续给叶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 .0 0 1) .表明芜菁叶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 。
The protection and repair effects of Brassica rapa leaf juice on radio damage mouse induced by 60Coγ rays were studied with the methods of measuring hemogram of mice,classifying of WBC,measuring wieght of the spleens and chest glands,and the micronucleus test. The results show that leaf juice of Brassica rapa irrigated after or before radiation was significantly effective in curing the decreasing of white blood cell ,red blood cell and platelet induced by 60Coγ radiation . The leaf juice of Brassica rapa could also protect normal immune function of spleen and thymus of mice and increase the immunocyte number. The leaf juice of Brassica rapa could apparently reduce micronucleus of PCE induced by 60Coγ rays in bone narrow of mice. It shows that leaf juice of Brassica rapa can remarkably protect and repair the injury radiated with 60Coγ rays. So the leaf juice of Brassica rapa has efficient capacity of antiradiation and repair the injury of radiation. The possible mechanism of antiradiation of leaf juice of Brassica rapa was discussed in the paper.
