摘要 目的:对脊髓损伤大鼠组织中不同时间段的Rab3a表达情况进行观察,研究Rab3a在损伤的脊髓组织中对神经再生的影响。方法:SD大鼠56只,随机分成7组,6组制作成急性脊髓损伤模型,另一组作为对照组。分别于伤后0h、6h、12h、24h、48h、72h,采用免疫组化法检测损伤脊髓组织中Rab3a的表达。结果:免疫组化法显示Rab3a在脊髓损伤后6h表达下降到最低,之后有所升高,1d表达最高,后再次降低。结论:Rab3a在脊髓损伤后6h表达不明显,之后随着时间的延长表达逐渐增加,1d后再次降低,表明脊髓损伤后Rab3a表达随时间先降低而后升高,之后再次降低的变化,对脊髓损伤动物神经功能的恢复有重要作用。
