Aim: Today, spinal cord injury (SCI) can be rehabilitated but cannot be treated adequately. This experimental study was conducted to investigate possible beneficial effects of methylprednisolone and parecoxib in treatment of SCI. Materials and methods: Forty-eight male Wistar albino rats were assigned into CONTROL, acute (MP-A, PX-A, and PXMP-A), and subacute (MP-S, PX-S, and PXMP-S) stage groups. Then, to induce SCI, a temporary aneurysm clip was applied to the spinal cord following T7-8 laminectomy, except in the CONTROL group. Four hours later parecoxib, methylprednisolone, or their combination was administered to rats intraperitoneally except CONTROL, SHAM-A, and SHAM-S groups. Rats in the acute stage group were sacrificed 72 h later, and whereas rats in the subacute stage were sacrificed 7 days later for histopathological and biochemical investigation and for gene-expression analyses. Results: Parecoxib and methylprednisolone and their combination could not improve histopathological grades in any stage. They also could not decrease malondialdehyde or caspase-3, myeloperoxidase levels in any stage. Parecoxib and methylprednisolone could decrease the TNF-? gene expression in subacute stage. Methylprednisolone could increase TGF-1ß gene-expression level in acute stage. Conclusion: Neither of the experimental drugs, either alone or in combination, did not show any beneficial effects in SCI model in rats.
