Objective to evaluate the functional recovery of acute spinal cord injuried rats treated with exogenous wnt-3a signal protein administration and to explore its mechanism.methods moderate spinal cord contusion injury was made in 40 adult sprague dawley rats at t10.twenty rats served as contusion controls(group 1).twenty rats were treated with wnt-3a for three days after injury (group 2).the functional recovery of the rats was observed through basso,beattie,bresnahan open field locomotor score.rats were killed at 14 or 28 days after injury,then spinal cords were removed for histopathological examinations,and the expression of the bromodeoxyuridine plus neural cell markers was stained with immunohistochemical method.results rats of two groups receiving a contusive injury recovered substantial function within 1 week.by 28 days,rats in groups 2 scored 7.0 points better on the bbb scores than rats in group 1 group 2=16.94,after 28 days vs.

目的 研究外源性wnt-3a信号蛋白对脊髓损伤的修复作用，并探讨其作用机制。方法取40只成年雌性sd大鼠在t10节段制备适度脊髓挫伤模型。随机从中取20只为损伤对照组(group 1)，另外20只为损伤治疗组(group 2)。脊髓损伤3天后用wnt-3a蛋白治疗。这些大鼠的功能恢复通过basso、beattie、bresnahan开放视野运动评分来观察。这些大鼠分批在损伤后14天或28天被处死，取出损伤节段脊髓用来组织病理学检查，同时用5-溴脱氧尿嘧啶核苷和神经细胞标记物进行免疫组化染色。结果两组大鼠在伤后一周运动功能有明显的恢复。不过，到损伤后28天，我们观察发现，损伤治疗组中的大鼠bbb评分比损伤对照组中的评分高出7.0分左右(group 2∶16.94±1.18，group 1∶9.89±1.29；p.05)，光镜和电镜检查发现wnt-3a蛋白对髓鞘形成和轴突再生有一定的修复效果。
