Abstract

OBJECTIVE To investigate the effects of hydroxyethylpuerarin on expression of ICAM-1 and VCAM-1 in rats with focal cerebral ischemia-reperfusion injury and explore its mechanism of action.METHODS Rats were subjected to cerebral ischemia-reperfusion injury by middle cerebral artery occlusion(MCAO).After 2 h ischemia and 24 h reperfusion,the protein and mRNA expression of ICAM-1 and VCAM-1 were evaluated by Western blot and RT-PCR analysis.RESULTS Hydroxyethylpuerarin significantly reduced the expression of ICAM-1 and VCAM-1 in ischemic brain tissue after cerebral ischemia-reperfusion.CONCLUSION Hydroxyethylpuerarin may attenuate ischemic brain injury by down-regulation the expression of adhesion molecules in ischemic brain tissue.

Key words
