目的 探讨外伤性癫痫患者颞叶癫痫灶组织γ-氨基丁酸B受体亚单位(gamma-aminobutyric acid B receptor subunit,GABABR1)和谷氨酸受体亚单位(glutamic acid receptor subunit,GluR1)的表达变化,以期为阐释外伤性癫痫发生机制和法医学鉴定提供依据.方法 收集15例外伤性癫痫患者脑皮质(外伤性癫痫组)、15例非外性癫痫患者脑皮质(非外伤性癫痫组)、15例交通事故死亡者脑皮质(交通事故死亡对照组),运用荧光免疫组化技术和RT-PCR技术观察GABABR1和GluR1的表达水平.结果 外伤性癫痫组GABAB R1表达水平明显低于对照组,但高于非外伤性癫痫组;外伤性癫痫组GluR1表达水平明显高于对照组,但低于非外伤性癫痫组.结论 GABABR1和GluR1的表达水平的变化在外伤性癫痫病的发病过程中起着一定的作用,可以作为区分外伤性癫痫与非外伤性癫痫的病变化指标之一.
