摘要: Aneurismal subarachnoid haemorrhage (SAH) is a devastating disease that associated with significant morbidity and mortality. The mortality approximately 50%, 30% of survivors having morbidity. There substantial evidence to suggest oxidative stress in the development acute brain injury cerebral vasospasm following SAH. are several sources for excessive generation free radicals SAH, including disrupted mitochondrial respiration extracellular hemoglobin. also upregulation radical producing enzymes such as inducible nitric oxide synthase (iNOS), xanthine oxidase, NADPH oxidase (NOX), well involved metabolism arachidonic acid. Additionally, intrinsic antioxidant systems superoxide dismutase (SOD) glutathione peroxidase (GSH-Px) inhibited. Experiments have linked apoptosis neurons endothelial cells, BBB breakdown altered contractile response vessels Antioxidant therapy has provided neuroprotection antispasmotic effects experimental SAH some therapies demonstrated improved outcomes clinical trials. These studies laid foundation use antioxidants treatment aneurismal
