摘要: 目的 研究银耳多糖注射剂对辐射损伤小鼠造血功能的防护作用。方法 用内源性脾结节形成,股骨有核细胞计数及脾脏指数等方法观察银耳多糖在6mg/kg、12mg/kg、24mg/kg三个剂量时对137Csγ射线照射7.5Gy后小鼠造血功能的影响。结果 照射前连续3d给药,照后第9天受照小鼠的股骨有核细胞数、脾结节和脾指数与对照组相比有明显的增高,经统计学处理有显著性差异。结论 银耳多糖对辐射损伤小鼠造血系统具有保护作用。Abstract: Objective To study the protective effects of polysaceharides of Tremella fueiformis on hematopoietic function in radiation-injured mice.Methods Colony-forming unit of spleen(CFU-S), number of nucleated cells in bone marrow (BMNC) and spleen index were used to investigated the effect of polysaccharides from tremella fuciformis at 6mg/kg、12mg/kg、24mg/kg on hematopoietic function of mice irradiated with 7.5 Gy 137Csγ-rays.Results On the 9 th day after irradiation compared with the negative control group number of nucleated cells in bone marrow, colony-forming unit of spleen and spleen index of mice have treated with polysaccharides from Tremella fuciformis intraperitoneally for three days prior to irradiation increased markedly.Conclusion Polysaccharides of tremella fuciformis have protective effect on hematopoietic function of radiation-injured mice.
