小鼠经用~(226)Ra内照射及X线外照射后,将其骨髓细胞注射给800拉德照射的同系小鼠,观察其脾结节的生成量及脾结节内的细胞数,从而来反映照射对小鼠造血干细胞增殖和分化能力的影响。方法;采用ICR雌性小鼠,10～13周龄.体重25克,分成3组,前2组腹腔注射~(226)Ra(第一组为0.56微居里/鼠,第二组为0.46微居里/鼠),第
After internal irradiation with 226 Ra and external X-rays, the mice were injected with 800 rad irradiated syngeneic mice to observe the production of spleen nodules and the number of cells in spleen nodules. In order to reflect the effect of irradiation on the proliferation and differentiation of hematopoietic stem cells in mice. METHODS: ICR female mice, 10 to 13 weeks of age, weighing 25 g, were divided into 3 groups. The first two groups were intraperitoneally injected with ~ (226) Ra (the first group was 0.56 microcuries/rat, and the second group was 0.46 micro. Curie/rat)
