与离体细胞染镉的方法比较 ,采用活体小鼠染镉观察骨髓细胞ＤＮＡ的损伤情况 ,更能全面地反映镉对ＤＮＡ损伤的实际状况。为此 ,我们采用活体小鼠连续染镉 ,用ＳＣＧＥ方法检测了镉对活体小鼠骨髓细胞ＤＮＡ的损伤作用。1　材料与方法1 1　动物　昆明种雌、雄小鼠 ,取自本校动 Compared with the method of cadmium in vitro, cadmium staining in vivo was used to observe DNA damage in bone marrow cells, which could reflect the actual status of cadmium damage to DNA. To this end, we used continuous in vivo cadmium staining of cadmium, SCGE method was used to detect the DNA damage of live mouse bone marrow cells. 1 Materials and methods 1 1 animal Kunming female, male mice, taken from the school move
