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 radioimmuological techniques are applied to examine the level of endothelin, and to flid the pathological changes under microscope and electron-microscope. Results The quantity of endothelin and calcium in the cell with 1, 4-dihydropyridine calcium 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 ln order to protect the function and to gain much precious opportunity for spinal recovery and other treatment.展开更多

However, little has been studied on the neuroprotective effects on spinal cord injury by activating Akt phosphorylation. We hypothesized that both effects of rapamycin, the increased autophagy activity and Akt signaling, would contribute to its neuroprotective properties. In this study, a compressive spinal cord injury model of rat was created by an aneurysm clip with a 30 g closing force. Rat models were intraperitoneally injected with rapamycin 1 mg/kg, followed by autophagy inhibitor 3-methyladenine 2.5 mg/kg and Akt inhibitor IV 1 μg/kg. Western blot assay, immunofluorescence staining and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay were used to observe the expression of neuronal autophagy molecule Beclin 1, apoptosis-related molecules Bcl-2, Bax, cytochrome c, casp ase-3 and Akt signaling. Our results demonstrated that rapamycin inhibited the expression of mTOR in injured spinal cord tissue and up-regulated the expression of Beclin 1 and phosphorylated-Akt. Rapamycin prevented the decrease of bcl-2 expression in injured spinal cord tissue, reduced Bax, cytochrome c and caspase-3 expression levels and reduced the number of apoptotic neurons in injured spinal cord tissue 24 hours after spinal cord injury. 3-Methyladenine and Akt inhibitor IV intervention suppressed the expression of Beclin-1 and phosphorylated-Akt in injured spinal cord tissue and reduced the protective effect of rapamycin on apoptotic neurons. The above results indicate that the neuroprotective effect of rapamycin on spinal cord injury rats can be achieved by activating autophagy and the Akt signaling pathway.展开更多
