Acute cerebral ischemia reperfusion

Since the early 1980s, much effort has focused on animal models of acute and chronic neurodegeneration in search of therapeutics for stroke. Neuronal cell death follows strokes, acute ischemic insults, and chronic neurodegeneration, such as Parkinson s disease, Alzheimer s disease (AD), epilepsy, and Huntington s disease. Up to 80% of all strokes result from focal infarcts and ischemia in the middle cerebral artery (MCA), so the commonly used animal models for neuroprotection are produced by temporary or permanent occlusion of the MCA.5 Lesions of the MCA include occlusion by electrocoagulation, intraluminal monofilaments, photochemical effects, thrombosis, and endothelin-1, but all of these models necessitate studying reperfusion events and validating MCA occlusion by behavioral assessments.
