目的观察参附汤联合同种异体NK细胞(alloreactive naturall killer cells,alloNK)对移植小鼠术后外周血象、骨髓有核细胞计数(nucleated cell counts,NCC)、骨髓造血组织容量(hematopoietic volume of bone marrow,HV)及骨髓病理的影响...目的观察参附汤联合同种异体NK细胞(alloreactive naturall killer cells,alloNK)对移植小鼠术后外周血象、骨髓有核细胞计数(nucleated cell counts,NCC)、骨髓造血组织容量(hematopoietic volume of bone marrow,HV)及骨髓病理的影响。方法BALB/c小鼠经过13.0 Gy剂量的全身照射(total body irradiation,TBI),4 h内经尾静脉注入供鼠骨髓单个核细胞(mononuclear cells,MNCs)8×10^(6)/kg,制作移植小鼠模型,然后随机分为模型组、alloNK组、参附汤组、参附+alloNK组4组,分别给予生理盐水、单用alloNK、单用参附汤和参附汤联合alloNK灌胃,观察治疗前及治疗后第7、14、30天,小鼠外周血象、骨髓NCC、HV及组织病理的变化。结果移植前及移植后第7天各组小鼠外周血象、骨髓NCC、HV无显著性差异。移植后第14天,模型组小鼠白细胞仍处于粒缺期,而单纯alloNK组和参附组小鼠的白细胞均有所上升,参附联合alloNK组小鼠上升幅度高于其他组。移植后第30天,模型组、alloNK组及参附组小鼠白细胞、骨髓NCC、HV均较前回升,但仍低于移植前水平,而参附联合alloNK组小鼠的白细胞、骨髓NCC、HV恢复至移植前水平,与其他组相比差异显著。结论参附汤可保护骨髓免受放射损伤、促进造血功能恢复、缩短粒细胞缺乏时间,而联合alloNK细胞促进造血功能恢复的作用更明显。展开更多
