Magnesium efficacy in a rat spinal cord injury model

Abstract

The rats receiving magnesium had significantly better BBB motor scores and white matter sparing 4 weeks after moderate-to-severe SCI than control animals. In addition, the groups given steroids only or magnesium and steroids had improved white matter sparing, although the limited numbers of animals reaching the study end point makes it difficult to draw firm conclusions about the utility of steroids in this model. The optimal timing of magnesium administration appears to be within 8 hours of injury.
