Objective To approach the effect of microgene pSVPoMcat to modify genetically Schwann cells (SC) on central conduction functionafter spinal cord injury (SCI) . Method Experimental animals were divided into three groups: the group of microgene pSVPoMcat implanted to genetically modify SC (group A), SC implanted group (group B), and the control group (group C). The cortical somatasensory evoked potentials (CESP) and combined behavioral score (CBS) were continuous monitored from operation second week to twelfth week Result The result showed that the peak latency and peak amplitudes of group A, B have a recovery tendency and it was constant with CBS. Conclusion We concluded that the microgene pSVPoMcat to modify genetically Sc may play a promotion role in recovery of central conduction function after SCI.  相似文献

Objective To study the effect of microgene pSVPoMcat implanted to modify schwann cell on growth associated protein-43(GAP-43) expression after spinal cord injury in adult rats.Method Hemisected of the T8 segment of the spinal cord was performed for all the experiment rats.The rats were randomly divided into three groups as follows:Group A with microgene pSVPoMcat implanted to genetically modify SC;Group B with SC implanted ;Group C with hemisection of the spinal cord only.The changes of expression of GAP-43 in spinal cord were observed by immunochemistry with antibodies against GAP-43 .Simultaneous,the combined behavioral scores(CBS)was measured.Result There were not any different(P >0.05)among the three groups in first week and 12 week.There were significant diffeence(P<0.05)among three groups in 2nd,8th,and more dxpression of GAP-43 at the 2nd week in group A.The neurofunctional recovery was best in group A.Conclusion The microgene pSVPoMcat implanted to modify schwann cell can promote the expression of GAP-43 in spinal cord and functional recovery in adults rats after SCI.  相似文献

Objective To approach the effect of microgene pSVPoMcat modified Schwann cell (SC) on the regeneration and repair of injured spinal cord.Method Spinal cord hemi- transection models were made with the cutting method in healthy SD rats. Microgene pSVPoMcat modified SC(group A),highly purified SC(group B),and glutin sponge (control group C)were randomly implanted into the cut. After 3 month living ,the host rats were scanned by MRI, and observed under EM. Result Spinal signals at the injury region nearly recovered to normal in group A.No recovery was found in group B.Malacosis was found in group C.TEM findings: regeneration of large number of myelinated and nonmyelinated axons and SC proliferation in group A, myelinated axon regeneration and SC necrosis in group B, non myelinated and nonmyelinated axon in group C.Conclusion Implantation of microgene pSVPoMcat modified SC could promote the repair of injured spinal cord.  相似文献

Objective To study the protective effects of the intracord transplantation of microgene pSVPoMcat- genetically- modified Schwann cells (MSCs)on spinal cord injury (SCI).Method Rats with semi- division(SD) of the spinal cord was divided into 4 groups.Group S consisted of the rats with SD treated with the transplantation of MSCs, Group B of the rats with SD treated with the transplantation of SCs without genetic modification,Group C of the rats with SD without treatment and Group D was the normal control. 8 hours after operation,the half of the rats of each group were killed and the injured segment of the spinal cord was resected to be examined with atomic absorption spectrophotometry . Another half of the rats of all the groups were examined with neurological function tests to have a combined behavioral score (CBS).Result There was a significant increase of water content and Na+ and Ca2+ ions and a decrease of K+ and Mg 2+ ions in the injured cord segment of Group C and a statistically significant recovery was observed in Group A. The intracord transplantation of pSVPoMcat genetically modidied SCs improved the neurological outcome of spinal cord injury.Conclusion Our findings indicate that intracord transplantation of pSVPoMcat- genetically- modified- Schwanncells exerts protective effects on the injured segment of the spinal cord through the improvement of the internal ion environment of the spinal cord.  相似文献

Objective In order to observe the role of genetically modified Schwann cell (SC) with pSVPoMcat in the regeneration of injured spinal cord.Method The cells were implanted into the spinal cord.Ninety SD rats were used to establish a model of hemi- transection of spinal cord at the level of T8,and were divided into three groups,randomly, that is,pSVPoMcat modified SC implantation(Group A), SC implantation(Group B),and without cell implantation as control(Group C).After three months the presence of axonal regeneration of the injured spinal cord was examined by means of horseradish peroxidase(HRP)retrograde labeling technique and stereography.Result The results indicated that HRP labeled cells in Group A and B could be found in the superior region of injured spinal cord and the brain stem such as the red nuclei and oculomotor nuclei. The density of ventral horn neurons of the spinal cord and the number of myelinated axons in 100 μ m of the white matter was A >B >C group.Conclusion In brief,the pSVPoMcat modified SC intraspinal implantation could promote regeneration of the injured spinal cord.  相似文献

背景直流电场能促进脊髓再生,但伤后6 h置入电刺激器的疗效比伤后立即置入电刺激器的疗效为差,可能于脊髓损伤后出现脊髓水肿有关.目的探讨直流电场与大剂量甲基强的松龙联合应用治疗完全性脊髓损伤的疗效.设计随机对照实验.地点和对象实验在海南省人民医院完成.对象为33只中国家犬,体质量10~12kg,犬龄1.5~2岁,由海南省动物中心提供.干预将33只家犬随机分成3组,用AllenWD法致脊髓完全损伤.A组为对照组;B组脊髓损伤6 h时置入电刺激器组;C组脊髓损伤2 h静滴大剂量甲基强的松龙,脊髓损伤6 h再置入电刺激器组.主要观察指标伤后各组1,2,3个月神经功能、皮层体感诱发电位、神经元数量、神经元截面积和内氏体密度恢复情况.结果神经功能评分A组伤后1~3个月均为1分;B组伤后1个月3分,伤后2,3个月均为4分;C组伤后1个月4分,伤后2,3个月均为5分.B,C组1,2,3个月神经功能、皮层体感诱发电位、神经元数量、神经元截面积和尼氏体密度恢复均优于同时期A组(P<0.05或P<0.01).此外,C组优于B组,差异有显著性意义.结论直流电场能有效地促进脊髓再生,直流电场与大剂量甲基强的松龙联合应用能有效地协同治疗脊髓损伤,特别是促进神经功能早期更好的恢复.  相似文献

目的建立有效、可靠的完全脊髓横断动物模型,探讨多个完整胚胎脊髓移植联合脑源性神经营养因子(BDNF)对脊髓完全横断损伤的修复作用。方法将Wistar雌性大鼠分为正常对照组,手术组A组(单纯横断)、B组(横断+BDMF)、C组(横断+移植)、D组(横断+移植+BDNF)。手术显微镜直视下切除大鼠脊髓3-4mm,镜下观察确保完全离断,取3—4个完整胚胎脊髓同时移植。B组及D组应用微型泵定时定量泵入BDNF溶液(2mg/ml)。术后1—6周进行功能锻炼及行为学分析。结果术后A组、B组后肢运动功能未恢复;术后3W,C组及D组开始恢复后肢运动功能,术后6W出现协调踏步动作。术后1,2W,C组与D组CBS行为学评分无显著性差异(P〉0.05),术后3W、4W,CBS评分差异有显著性(P〈0.01)。结论本实验成功的建立了大鼠完全脊髓横断模型。多个完整胚胎脊髓组织移植解决了脊髓完全离断情况下所需移植物总量较大的问题,联合应用BDNF,对脊髓损伤修复效果更为理想。  相似文献
