Abstract:
Objective Acute spinal injury(ASI) is a kind of disease commonly seen in the orthopedic department, with secondary pathological injury causing the delayed damage of tissue structure. This study is focused on finding the injury mechanism of endothelin and the relation with calcium in SCI, and developing an effective treatment of SCI through animal experiment for clinic application in the future. Methods ASI animal model with radioimmuolo gical techniques are applied to examine the level of endothelin, and to find the pathological changes under microscope and electron-microscope. Results The quantity of endothelin and calcium in the cell with 1, 4-dihydropyridine calci um channel inhibitor is decreased, as a result, depolarization was lightened. The mechanism delays the development of secondary injury significantly. Conclusion This type of treatment may be used in emergency for spinal cord injury in order to protect the function and to gain much precious opportunity for spinal recovery and other treatment.
