ABSTRACT
Objective To study the protective mechanism of Buyang Huanwu decoction(补阳还五汤) on brain damage after focal cerebral ischemia/reperfusion(I/R)in aged rats from the expression changes of nuclear factor-?B(NF-?B),heat shock protein 70(HSP70)and nitric oxide synthase(NOS).Methods A focal cerebral ischemia model was established by middle cerebral artery occlusion(MCAO),and the models were duplicated.Ninety-six aged rats were randomly divided into four groupssham-operated group,model group,nimodipine group(6 mg?kg~(-1)?d~(-1)),Buyang Huanwu decoction group(0.9g?kg~(-1)?d~(-1)).The ischemia(I)was performed for 3 hours and reperfusion(R),for 1,3,6 and 12 days.The effects of Buyang Huanwu decoction on the nervous dysfunction score,the water content of cerebral constitution and the expressions of NF-?B,HSP70 and NOS were observed at different time points of reperfusion.Results The nervous dysfunction score,the water content of cerebral constitution,the expressions of NF-?B,HSP70, endothelial nitric oxide synthase(eNOS),neuronal nitric oxide synthase(nNOS),and inducible nitric oxide synthase(iNOS)in the model group were higher than those of the sham-operated group(P
