摘要 目的:探讨戊四氮慢性点燃大鼠在癫痫形成过程中海马区PPARγmRNA表达变化及神经细胞损伤,探讨PPARγ在癫痫发作后神经元炎症损伤的潜在作用机制。方法:将40只SD雄性大鼠随机分为正常组、PTZ组,除正常组外均给予戊四氮(PIZ)35mg/kg·d腹腔注射,持续28d。实验结束后以RT-PCR法检测检测不同时间点(24h、48h、72h)海马区PPARγmRNA含量,同时尼氏染色观察海马组织形态变化。结果:通过RT-PCR及尼氏染色,PTZ组大鼠脑海马PPARγmRNA含量比正常对照组增高,注射PIZ的各组大鼠海马区PPARγmRNA的表达随着注射时间逐渐增加,尼氏染色显示PTZ组海马区炎症改变较正常组显著。结论:PPARγ低表达可能是癫痫发作后神经元炎症损伤的潜在机制之一。
