摘要: 目的: 建立阿糖胞苷诱发时间更快和更稳定的小鼠血小板减少模型。方法: 小鼠腹腔分别注射200 和100mg°kg-1 阿糖胞苷, 造成血小板减少, 观察两组动物外周血象 、骨髓涂片和脾脏、肾上腺、胸腺重量的变化。结果: 两种剂量的阿糖胞苷都能成功造成小鼠血小板减少模型, 在诱发时间和稳定性方面200 mg°kg-1 阿糖胞苷组优于 100 mg°kg-1 阿糖胞苷组, 除血小板数之外,两剂量组的其它观察指标无明显区别。结论: 200 mg°kg-1 阿糖胞苷组造成的小鼠血小板减少模型诱发时间更快、稳定性更好。

Abstract: AIM: To establish a mouse model of cy-tosine arabinoside (Ara-c) induced thrombocytopenia which leads inducement time more quickly and stably. METHODS: The mice were injected different dosages cytosine arabinoside (Ara-c)in two groups, respectively. The change of thrombocytopenia was observed in peripher-al hemogram and smear of marrow, andweightsof spleen, adrenal gland and thymus gland also were observed. RESULTS: The high dosage (200 mg°kg-1)to the model formation was better than low dosage (100 mg°kg-1)at inducement time and stability. The index showed no sig-nificant different between two groups except the volume of thrombocyte. CONCLUSION: Cytosine arabinoside-in-duced thrombocytopenia at high dosage (200 mg°kg-1) can induce thrombocytopenia more effectively.
