目的研究高压氧(HBO)治疗对脊髓损伤(SCI)组织中神经生长相关蛋白(GAP-43)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鼠随机分为正常组、SCI对照组和HBO治疗组。治疗组于术后每天HBO治疗1次,对照组无特殊治疗。各组分别于术后1 d、4 d、7 d、10 d、14 d各随机取鼠5只,取损伤脊髓组织, Western blot法检测GAP-43表达水平。 结果GAP-43在正常成年鼠脊髓中少量表达,SCI后表达增加且HBO治疗组较对照组表达更为显著。术后1周时SCI对照组GAP-43表达达到高峰, 2周时降至接近初始水平,但HBO治疗组GAP-43表达仍维持高水平。 结论HBO可增强损伤脊髓组织GAP-43表达。 |

Objective To investigate the effect of hyperbaric oxygen (HBO) on expression of GAP-43 in the rats spinal cord following spinal cord injury (SCI). MethodsFifty-five Wistar rats were randomly divided into three groups: a normal group, a control group and a HBO-treatment group. The rats in the control and HBO-treatment group underwent SCI by 10g×5cm impact at the T10 level. The rats in the HBO-treatment group were treated by HBO. Western blot was used to observe the change of expression of GAP-43. ResultsThere was weak expression of GAP-43 in the normal spinal cord. The GAP-43 expression increased significantly following SCI. The level of GAP-43 expression in the HBO-treatment group was significantly high than that in the control group. ConclusionHBO can increase the level of GAP-43 expression. |
