摘要: 为探讨星形胶质细胞在戊四唑(pentylenetetrazol,PTZ)化学点燃癫痫形成过程中的作用,采用免疫组织化学方法和图像分析技术,对PTZ点燃各发作级别大鼠大脑皮质部位的胶质纤维酸性蛋白(glial fibrillary acidic protein,GFAP)的变化进行动态观察。发现:GFAP值于点燃后Ⅲ级组开始增加,Ⅴ级组达到高峰。表明:在戊四唑点燃癫痫模型中,随着点燃级别的进展,GFAP的免疫表达逐渐增加。提示:星形胶质细胞GFAP含量的增加,可能是PTZ点燃模型癫痫发病的原因之一。

Abstract: The aim was to explore the role of astrocytes in the pentylenetetrozal kindling model. With the immunohistochemical method and the image analyzing system, changes of GFAP immunoreaction positive cells in the cortex of PTZ kindling rat were observed at each stage. After PTZ injection in rats, GFAP change began increasing at Ⅲ-Grade group, reaching peak at V-Grade group. In the epilepsy model of PTZ kindling, as the progress of kindling, the express of GFAP immunoreaction increased gradually. It suggests that increased GFAP may be one of the reasons for epilesic seizure by PTZ kindling.

Key words: pentylenetetrazol, kindling, cortex, glial fibrillary acidic protein(GFAP)
