Abstract:
Aim To observe the neurological protective effects of astragalosides(AST) on focal cerebral ischemia-reperfusion(I/R) injury in rats and to explore its possible mechanism.Methods Male SD rats received right middle cerebral artery occlusion for 120 min,and were decapitated 1,3,7,and 14 days after reperfusion.AST(40 mg?kg-1) was orally administered after I/R.Neurological deficit score was daily determined,the expressions of BDNF and p75NTR mRNA were detected by RT-PCR,and the expression of TrkB mRNA was detected by real-time PCR.Results AST reduced the neurological deficit score on days 3,increased the expression of BDNF mRNA on days 3,7 and 14,decreased p75NTR mRNA and increased TrkB mRNA on days 3 and 7.Conclusions AST improves the neurological deficits after I/R in rats.The mechanism may be related with increasing BDNF,and TrkB mRNA,and decreasing p75NTR mRNA.
