The present study explored the effects of morphine on plasticity of spinal cord in three parts as follows: 1. the effects of morphine on dorsal root terminal in spinal lamina Ⅱ of spared root rat---- a quantitative study by FRAP histochemistry; 2. the effects of morpnine on synaptic reinnervation in spinal lamine Ⅱ of spared root rat----an EM quantitative study and 3. the effects of morphine on collateral sprouting of nerve fiber in spared root of rat----an EM quantitative study

Objective: To investigate the expression changes of Versican ofCSPGs family and its ligand CD44 in spinal cord in 3d, 7d and 14d following hemisection of spinal cord injury. Furthermore, to explore the relationships of Versican、CD44 and spinal cord injury. Besides, to offer the morphological datum for the research concerning the spinal cord repair.

目的：观察大鼠脊髓半横断损伤后3天、7天、14天，损伤处上下段硫酸软骨素蛋白多糖Versican及其配体CD44的表达变化，探讨Versican、CD44与脊髓损伤的关系，为脊髓损伤后的修复研究工作提供翔实的形态学资料。

Results: During the development of spinal cord. NIDD mRNA was highly expressed at embryo 16 d and at postnatal 1 d, and co-localized with nNOS in the undifferenti ated ventral horn, as well in white matter. And then it decreased significantly till postnatal 12w. nNOS mRNA was highly expressed from postnatal 1 d to 3 d. The high expression of NIDD mRNA appeared at the 8 hour after spinal cord injury, and co-localized with nNOS in neurons of ventral horn, intermedial zone, the area around central canal and dorsal horn, and recovered to the normal at dry 7 day after SCI.

结果：大鼠发育过程中，胚胎16 d的大鼠脊髓中可见NIDD mRNA的高表达，在生后1d，与nNOS共表达于尚未分化成熟的前角，在白质也见NIDD的阳性信号成年后呈低表达；nNOS mRNA于生后1~3 d出现表达高峰；脊髓损伤后NIDD mRNA表达明显增多，在8 h到达高峰，分布于脊髓前角，中间带、中央管周围及后角nNOS阳性的神经元，7 d恢复至正常水平；nNOS mRNA在损伤后8 h达到高峰，1 d降低至正常水平。

Those canines with cervical anterior spinal artery injury showed incomplete paraplegia of the hind legs postoperatively, but the myodynamia restored to I degree within 3 days.

In recent years , in company with development of the disciplinary , direction in the research was widen ,serial basic and clinical research have been done on treatment of encephalic malignancy ,neurotization and restoration rear injury of brain and spinal cord , diagnose and surgical treatment of complicated spinal cord diseases .

推广和交流在脊髓疾病外科治疗领域的最新进展和成果。近年来，随着学科的发展，研究方向不断拓宽，在颅内恶性肿瘤综合治疗、脑与脊髓损伤后的神经再生修复、复杂脊髓疾病的诊断与外科治疗等方面进行系列的基础与临床研究，并不断深入。

At this level, the upward projecting signals to higher-located centres and signals that eliciting spinal reflexes are subjected to complex modulatory effects coming from the descending fibers from supraspinal structures and propriospinal neurons through releasing some neuroactive substances, including neurotransmitters and neuromodulalors.

在这里，来自脊髓上结构的下行纤维和脊髓本身的局部神经元通过释放各种神经活性物质，包括神经递质和调质，对痛信号向高位中枢的上行传递和引起脊髓局部反射的过程，起着复杂的调制作用。

Immunoelectron microscopic examination revealed that mGluR5 was prominently located in some neuronal somata and a lot of dendrites within the superficial layers of the spinal dorsal horn. Some dendrites containing mGluR5 constituted synaptic glomeruli with the terminals exhibiting the morphological characteristics of primary afferent C fiber. The ultrastructural features indicated that mGluR5 in the dorsal horn of the spinal cord may prominently work as a postsynaptical receptor to mediate or modulate the function of glutamate in the primary sensory transmission, including the nociceptive transmission.

免疫电镜研究显示，在脊髓背角浅层内，mGluR5主要定位在部分神经元胞体和大量树突内，并常见部分含mGluR5的树突与具有一级传入C纤维终末形态特征的轴突终末构成突触小球。mGluR5在脊髓背角浅层内的超微定位特征表明，脊髓背角内的mGluR5可能主要作为突触后受体介导或调节谷氨酸传递一级感觉的功能。

Conversely, injury to the reticulospinal or vestibulospinal tracts, which normally inhibit spinal reflex pathways, results in "positive" symptoms including spasticity, hyperactive muscle stretch reflexes, abnormal cutaneous and autonomic reflexes, and co-contraction of agonist and antagonist muscles.

ConclutionDTI may be more sensitive in pristine wallerian degeneration of spinal cord compression and can reflact the degree of injury of spinal cord compression.DTI is more precise checking method and can provide valuable information of quantization for earlier diagnosis of spinal cord compression in vivo.

结论磁共振弥散张量成像技术对脊髓受压损伤早期发生的华勒氏变性改变较敏感，并能反应其受压损伤程度，是目前早期活体诊断脊髓受压损伤比较准确的检查方法，对脊髓压迫症能提供有价值的量化信息。

In this study, we explore the change on expression of Fas and FasL of promoting apoptosis at different period of time after spinal cord injury by making the model of transecting injury completely in SD rat and applying to the immunohistochemical method.
