中文摘要:
  目的:研究马尾神经受压后一氧化氮合酶(NOS)活性变化与腰骶髓神经细胞凋亡的关系。方法:将27只健康家犬随机分为3组:A组21只,水囊置于椎管内并注水加压制成马尾神经压迫模型(马尾神经压迫组);B组3只,置入水囊但未注水加压(假手术组);C组3只(正常组)。A组再分为7组,即马尾神经持续受压4h、8h、12h、24h、48h、72h和168h组(n=3)。检测各组腰骶髓组织中的NOS活性变化,用TUNEL法标记凋亡神经元和神经胶质细胞,光镜(HE染色)和透射电镜观察细胞形态学改变。结果:B组和C组腰骶髓神经细胞形态未见异常,A组光镜及电镜观察结果均提示神经细胞发生凋亡。B组和C组未见凋亡神经元,A组于压迫后12h可见凋亡神经元,24~48h神经元凋亡最多。B组与C组腰骶髓组织中NOS活性比较无显著性差异(P〉0.05),A组于压迫12h后,NOS活性即明显增高,与B组和C组比较有显著性差异(P〈0.05),24~48h达到高峰,72h后开始下降。结论:犬马尾神经受压后腰骶髓组织中NOS活性增高,与相应神经元凋亡存在正相关。
