Abstract:
:Previous work has shown that unsaturated fatty acid components of model membrane phospholipids in vitro, damaged via a free radical mechanism, are protected by the presence of cholesterol in these membranes. The participation of these membrane lipids in the pathogenesis of traumatic injury to brain was studied in vivo using the Klatzo method of cryogenic injury in rats. Increased edema 4 hr after cryogenic injury was noted on the lesioned side. Total cerebral cholesterol was decreased significantly in the lesioned hemispheres 10 hr following injury. In lesioned animals pretreated and post-treated with methylprednisolone, there were no significant differences in the cholesterol levels. Arachidonic acid isolated from total membrane phospholipids was significantly reduced on the injured side 24 hr after injury, but not before. Other fatty acids were not significantly affected. Methylprednisolone treatment prevented the decrease in arachidonic acid. Animals that had received a cold injury had significant decreases in ascorbic acid levels after 4 hr on the lesioned side of the brain. This decrease was significantly ameliorated by corticosteroid administration. These results support the hypothesis that the protective effect of corticosteroids in cryogenic cerebral trauma may be due to antioxidant protection of major cell membrane lipid components such as cholesterol and phospholipids.
