Abstract

Abstract:

Objective To explore the change of α-synuclein(α-Syn) in rat brain and plasma after ischemia/reperfusion. Methods Thirty adult male Wistar rats were randomly divided into 2 groups: sham operation group(10 cases) and ischemia/reperfusion group(20 cases). A model of middle cerebral artery occlusion(MCAO) was induced by the intraluminal suture for the latter group. After 1.5 h ischemia, reperfused for 24 h, then the level of α-Syn in the plasma and penumbra, infarct core and their controls were measured by Western blotting and ELISA method. Results The level of α-Syn was increased significantly in the penumbra, but did not change obviously in the infarct core or plasma. Conclusion α-Syn was increased in the penumbra of brain after ischemia/reperfusion.

Key words: &alpha, -synuclein, ischemia/reperfusion, penumbra, infarct core, plasma
