Abstract

目的 研究高压氧(HBO)治疗对脊髓损伤(SCI)组织GAP-43mRNA表达水平的影响.方法用Allen氏WD法制作鼠脊髓损伤模型.55只成年Wistar鼠随机分为11组:正常对照组、SCI后第1,4,7,10,14 d组和HBO(SCI后HBO治疗)第1,4,7,10,14 d治疗组,每组各5只.用半定量RT-PCR法检测鼠损伤脊髓组织中GAP-43mRNA表达水平.结果 GAP-43mRNA在正常成年鼠脊髓中微量表达, SCI后表达增加,且HBO治疗组较SCI组表达更为显著(P<0.01).术后7 d时,SCI组的GAP-43mRNA表达达到高峰,14 d时降至接近初始水平,但HBO治疗组GAP-43mRNA表达仍维持较高水平.结论 HBO可增强损伤脊髓组织GAP-43mRNA表达水平,促进损伤脊髓神经元再生和修复,对脊髓损伤起保护作用。
