Successful models were treated with a combination of Xuefuzhuyu decoction and 10g of astragalus. The experimental results showed that neuronal morphology and structure recovered, nerve growth factor mRNA expression increased in brain tissues, and neurological function signifi-cantly improved. There was no significant difference in these measures compared with rats treated with Xuefuzhuyu decoction alone or a combined treatment of Xuefuzhuyu decoction with 40 g as-tragalus. These experimental findings revealed that, Xuefuzhuyu decoction combined with astra-galus may up-regulate the expression of nerve growth factor mRNA and accordingly exert a neu-roprotective effect; however, this protection is not dependent on astragalus dosage.展开更多
