摘要: 目的:探讨建立大鼠SHG-44脑胶质瘤模型的方法。方法:选用雄性Wistar大鼠,接种前连续3 d用地塞米松1 mg/100 g体重灌胃;在立体定向条件下选取大鼠脑右侧尾状核区为靶点,接种2×105个处于对数生长期的SHG-44细胞,接种后观察大鼠生长状态,分别于第1、2周进行核磁共振(MRI)检查。在实验第2周时解剖标本,行组织病理和GFAP免疫组化检查。 结果:接种1周后核磁共振检查,脑内形成实体瘤;HE染色组织病理证实是胶质瘤,GFAP免疫组化阳性;成瘤率约60%。 结论:用预先免疫抑制的方法,成功建立了大鼠脑内人胶质瘤模型。

Abstract: Objective To establish solid intracerebral human glioma model in Wistar rat with xenograft methods. Methods The SHG-44 cells were injected into brain right caudate nucleus of previous immuno-inhibitory Wistar rats with stereotactic technique. The MRI scans were performed at 1 week and 2 weeks later after implantation. After 2 weeks the rats were killed and pathological examination and immunohistologic stain for human GFAP were used. Results The MRI scan after 1 week of implantation showed the glioma was growing,pathological histochemical examination demonstrated the tumor was glioma. Human GFAP stain was positive. The growth rate of glioma model was about 60%. Conclusion Solid intracrebral human glioma model in previous immuno-inhibitory Wistar rat is successfully established.
