摘要 目的热休克蛋白HSP72在大鼠脊髓缺血耐受中的表达及其作用。方法采用球囊阻断主动脉法建立大鼠脊髓缺血模型;RT-PCR测HSP72mRNA表达水平;免疫组化法测脊髓组织HSP72含量。结果与假手术组相比,缺血3min组HSP72mRNA表达呈再灌注时间依赖性增加,再灌注时间30min HSP72mRNA表达显著增高(P<0.05),2h达到峰值,24h后其表达开始下降;与缺血3min相比,缺血6min组再灌注30min显著增加(P<0.05),免疫组化显示:与假手术组相比,缺血3min组HSP72表达呈再灌注时间依赖性增加,再灌注时间30min HSP72表达显著增高(P<0.05),2h达到峰值,24h后其表达开始下降;与缺血3min组相比,缺血6min组再灌注30min,2h,24hHSP72均有统计学意义(P<0.05)。结论脊髓缺血一定时间后恢复血液供应,可以发生再灌注损伤;脊髓缺血灌注后HSP72的表达增加且增加水平与缺血时间有关。
