Abstract:
OBJECTIVETo investigate the effect of Buyang Huanwu Decoction (BYHWD) and the different combinations of its ingredients on neurogenesis following ischemic stroke in rats.
METHODSThe model rats of ischemic stroke was established by blocking cerebral media artery with electrocoagulation through craniectomy, and electric stimulation, given from 24 h after blocking, 2 h daily for 15 successive days. They were divided into four groups, Group A treated with saline, Group B treated with BYHWD, Group C treated with BYHWD but earthworm subtracted, and Group D treated with Danggui Buxue Decoction (DGBXD). The expression of 5-bromodeoxyuridine (BrdU) in cerebral tissue was determined by immunohistochemical method.
RESULTSLarge amount of BrdU immunoreactive cells presented in the hippocampal region of rats in Group B and C, densely arranged, partial in cluster, with the figure significantly different to that in Group A (P < 0.01), and the amount in the ischemic side was significantly more than that in the opposite side (P < 0.05). While comparing between Group A and D, the amount of BrdU immunoreactive cells in the hippocampal region showed insignificant difference (P > 0.05).
CONCLUSIONBYHWD has a effect in promoting neurogenesis better than DGBXD.
