- 摘要:
- 目的 比较3种不同方法建立的动物模型，探索建立造型简便且重复性好的大鼠动脉粥样硬化模型。 方法 健康雄性SD大鼠（体质量150~170 g）24只，按3种方法建立模型： ① 高脂造模组，高脂饲料9周；② 维生素D3造模组，维生素D3 40万单位灌胃3 d，标准饲料9周；③ 高脂维生素D3造模组,维生素D3 20万单位灌胃3 d，高脂饲料9周。采用HE染色鉴定各组的动脉粥样硬化病变形成情况。 结果 光镜下高脂组血管各层结构基本正常；维生素D3造模组出现典型动脉粥样病变的斑块结构；高脂维生素D3造模组血管壁钙化和平滑肌细胞增生，程度较维生素D3组减轻，未出现典型斑块结构。 结论 40万单位维生素D3 的造模方法能在较短时间内建立典型成熟的动脉粥样硬化斑块模型。
- Abstract:
- AIM To investigate the simple and successful method for establishing atherosclerotic rat model . METHODS Ｔhree groups of rats were obtained: high-fat fed (６ SD rats with high-fat diet for ９ weeks) ；vitamin D-treated (9 SD rats treated by 400,000 unit vitamin D for three days, common diet for ９ weeks )；vitamin Dtreated and highfat fed (9 SD rats fed by 200,000 unit vitamin D for 3 days and highfat diet for ９ weeks)。HE staining was used to verify the atherosclerotic lesion of three models. RESULTS high-fat fed rats almost had no morphologic change in light microscope, while vitamin D-treated rats existd typical atherosclerosis. Vitamin Dtreated and high-fat fed rats also showed semblable but much milder pathologic changes in light microscope . CONCLUSION Method of 400,000 unit vitamin D for three days, common diet for 9 weeks is convenient and stable to establish typical atherosclerotic rat model .
