The importance of the microcirculation is often ignored in spinal cord injury and repair research. Therefore, in this study, we established a rat model of intervertebral disc extrusion by inserting a silica gel pad into the left ventral sur-face of T13. Electroacupuncture was used to stimulate the bilateralZusanlipoint (ST36) and Neiting point (ST44) for 14 days. Compared with control animals, blood lfow in the ifrst lumbar vertebra (L1) was noticeably increased in rats given electroacupuncture. Microvessel density in the T13 segment of the spinal cord was increased significantly as well. The number of normal neurons was higher in the ventral horn of the spinal cord. In addition, vacuolation in the white matter was lessened. No obvious glial cell proliferation was visible. Furthermore, hindlimb motor function was improved signiifcantly. Collectively, our results suggest that electroacupuncture can improve neuronal morphology and microcirculation, and promote the recovery of neurological functions in a rat model of intervertebral disc extrusion.展开更多

Motornerve conduction time (MNCT) and MRCT were determined on tlhlalls and soleds. With MRCT theexciting point arter magnetic simulation over lumbosacral vertebral column could be round. Togetherwith the lengths or LS and SI root determined in 5 autopsies the exciting site is located in the intervertebral roramen berore the exit or the root. MNCT and MRCT were determined in 40 I,atients withiumhar disc herniation by the method with control. The result showed that no difrerence was seen inMNCT In all ~lents. It is concluded that magnetic stimulation of MEPs is an useful teckulque fornon-invaslve diagnosis of lumber disc kerniation.展开更多
