Abstract:
Objective To investigate the effect of Buyanghuanwu decoction(BYHWD) on the expression of growth-associated protein 43(GAP-43) and synaptophysin(SYP) after focal cerebral ischemia in mice.Methods Focal cerebral ischemia was induced by 30 min of middle cerebral artery occlusion followed by reperfusion.BYHWD (20 g/kg) was administered orally 24 h after ischemia and once a day.The neurological score and the corner test were used to evaluate sensorimotor function on 1,3,7,and 14 days after ischemia.The expression of GAP-43 and SYP in the ischemic boundary zone was determined by immunohistochemistry 14 days after ischemia.Results Compared with the model group,BYHWD significantly ameliorated neurological dysfunction at 3,7 and 14 days and reduced the number of right turn at 7 and 14 days after ischemia(P ＜ 0.05).The average optical density of GAP-43 and SYP was 0.217 ±0.012 and 0.278 ±0.019 at the boundary zone in model group 14 days after ischemia,respectively.BYHWD also significantly increased the immunoreactivity of GAP-43 (0.250 ± 0.013)and SYP(0.323 ± 0.017) (P＜ 0.01).Conclusion BYHWD promotes axonal regeneration and synaptic plasticity in the ischemic boundary zone,which may contribute to functional recovery after focal cerebral ischemia.
