骨髓抑制性贫血小鼠模型的研究

目的建立适用疗效观察的骨髓抑制性贫血小鼠模型。方法本实验采用BALB小鼠80只,分10组,每组8只,通过正常组、单纯照射组、单纯环磷酰胺注射组、照射加环磷酰胺注射组和照射加环磷酰胺加氯霉素注射组等复合造模比较骨髓造血情况。结果与正常组相比,所有造模组的血像和有核细胞数都显著性降低。根据死亡率和全血细胞数分析,复合造模照射加环磷酰胺组的效果最为突出。结论复合造模照射加环磷酰胺注射组是一种小鼠全血细胞下降骨髓抑制性贫血的理想模型。

几种骨髓抑制性贫血小鼠模型的比较研究

目的:辐射法和化学法均能使骨髓造血机能得到抑制,但其机理不同。目前常用的骨髓抑制贫血小鼠造模方式很多。通过对单纯照射、单纯环磷酰胺注射、照射加环磷酰胺注射复合造模3种造模方式进行了比较,认为复合造模(60Co2Gy+cy 50 mg)是一种理想的骨髓全面抑制造模方式。

肉苁蓉多糖对骨髓抑制性贫血小鼠造血调控的实验研究

目的:观察肉苁蓉多糖对骨髓抑制贫血小鼠造血功能的影响,探讨其造血调控作用机制。方法:采用CO60照射和注射环磷酰胺复合制备贫血小鼠模型。应用流式细胞术(FCM)检测肉苁蓉多糖对骨髓抑制贫血小鼠骨髓细胞周期的影响,采用造血祖细胞培养术观察三系造血祖细胞集落数。结果:低剂量和高剂量肉苁蓉多糖能明显促进骨髓G0/G1期细胞向S期细胞以及S期细胞向G2/M期细胞的转化,G2/M期细胞比例明显升高,增殖指数(PI)也明显升高。给药组CFU-E,BFU-E,CFU-MeG与贫血对照组集落数有显著差异。结论:肉苁蓉多糖可能通过促使骨髓抑制贫血小鼠骨髓细胞细胞周期的转化,促进骨髓造血功能的恢复,并促进红系巨核系造血。

健脾生血颗粒(片)治疗各型贫血作用解析

通过健脾生血颗粒(片)对缺铁性贫血、骨髓抑制性贫血、肾性贫血模型动物治疗作用研究结果的分析,并结合其处方特点及相应中医理论,解析健脾生血颗粒治疗各型贫血的作用依据,为该产品更深入的研究方向选择以及临床应用提供参考。

健脾生血颗粒对骨髓抑制性贫血模型小鼠的治疗作用

目的:探讨健脾生血颗粒对骨髓抑制性贫血模型小鼠的治疗效果。方法:采用Co60照射及腹腔注射环磷酰胺的方法,制备小鼠骨髓抑制性贫血模型。造模成功后,每组小鼠分别灌胃健脾生血颗粒、健脾生血浸膏、硫酸亚铁、生理盐水。3周后,考察外周血象(白细胞、红细胞)及白细胞介素-2水平。结果 :治疗后,实验组小鼠WBC、RBC均高于对照组,同时健脾生血颗粒组小鼠白细胞介素-2水平明显高于其余各组。结论:健脾生血颗粒、健脾生血浸膏、硫酸亚铁均可改善小鼠骨髓抑制性贫血状况,健脾生血颗粒效果明显优于其余各组。

Effects of Weiganli on the Hemopoietic Function of the Myelosuppressed Anemic Mice

Objective: To study the effect of Weiganli (维肝力)on bone marrow hemopoiesis. Methods: The effects of Weiganli on the peripheral blood picture and the number of bone marrow nucleated cells (BMCs) were observed in myelosuppressed anemic model mice, and the effects of Weiganli on the growth of colony forming unit-granulocyte macrophage (CFU-GM), colony forming unit-erythroid (CFU-E), burst forming unit-erythroid (BFU-E), colony forming unit-megkaryocyte (CFU-Meg) were investigated by in vitro cell culture technique. The hemopoietic stem cells (HSCs, c-kit+) in bone marrow were double stained with fluorescent antibody PE-C-Kit and FITC-CD45, and the HSCs (c-kit+) were counted by flow cytometer with CD45/SSC (side scatter) gating. Results: Peripheral blood cell counts and the number of BMCs were significantly improved after Weiganli administration; and bone marrow hemopoietic stem/progenitor cells were significantly increased. Conclusion: Weiganli can effectively promote the recovery of hemopoietic function in the myelosuppressed anemic mice.
