Abstract:
Free radicals are highly reactive molecules generated predominantly during cellular respiration and normal metabolism. Imbalance between cellular production of free radicals and the ability of cells to defend against them is referred to oxidative stress (OS). OS has been implicated as a potential contributor to the pathogenesis of ischemic cerebrovascular diseases. After brain injury by ischemia, the production of reactive oxygen species (ROS) may increase, leading to tissues damage via several different cellular molecular pathways. Radicals can cause damage to cardinal cellular components such as lipids, proteins, and neucleic acids, leading to subsequent cell death by modes of necrosis or apoptosis. Treatment with antioxidants may prevent propagation of tissues damage and improve both the survival and neurological outcome. The present paper reviews the antioxidants therapy in ischemic cerebrovascular disease, discusses probable reasons of inconsistency between animal experiments and clinical trials on antioxidants, and puts forward strategies against oxidative stress in the treatment of ischemic cerebrovascular diseases.
