Involvement of lipid peroxidation in CNS injury.
The generation of oxygen radicals and the process of lipid peroxidation have become a focus of attention for investigators in the fields of central nervous system (CNS) injury and stroke (e.g., ischemia). While absolute proof for their involvement in the pathophysiology of traumatic and ischemic damage to the CNS remains to be established, numerous recent studies have provided considerable support for the occurrence of free radical and lipid peroxidation reactions in the injured or ischemic CNS. Furthermore, the use of antioxidants and free radical scavengers in the treatment of experimental and clinical CNS trauma and ischemia has provided convincing support for the involvement of oxygen radicals and lipid peroxidation in these conditions. In this report we will review some of the history behind the hypothesis for an involvement of oxygen radical-mediated lipid peroxidation in the pathophysiology of CNS injury and look at some of the more recent work conducted in this area.
