  • Title: Brain protection by methylprednisolone in rats with spinal cord injury.
    Author: Chang CM, Lee MH, Wang TC, Weng HH, Chung CY, Yang JT.
    Journal: Neuroreport; 2009 Jul 01; 20(10):968-72. PubMed ID: 19525878.
    Abstract:
    Traumatic spinal cord injury is clinically treated by high doses of methylprednisolone. However, the effect of methylprednisolone on the brain in spinal cord injury patients has been little investigated. This experimental study examined Bcl-2 and Bax protein expression and Nissl staining to evaluate an apoptosis-related intracellular signaling event and final neuron death, respectively. Spinal cord injury produced a significant apoptotic change and cell death not only in the spinal cord but also in the supraventricular cortex and hippocampal cornu ammonis 1 region in the rat brains. The treatment of methylprednisolone increased the Bcl-2/Bax ratio and prevented neuron death for 1-7 days after spinal cord injury. These findings suggest that rats with spinal cord injury show ascending brain injury that could be restricted through methylprednisolone management.
