Protective Action of Ultramicro-powder of Rhizoma Gastrodiae on Nerves in the Rat of Cerebral Ischemia-Reperfusion Injury / 中医杂志

ABSTRACT

Objective:To explore protective action of ultramicro-powder of Rhizoma Gastrodiae on nerves in the rat of Cerebral ischemia- reperfusion injury.Methods:The local ischemia-reperfusion injury at model was established by cerebral ischemia for 2 hours and reperfusion for 24 hours.HE staining,2,3,5-triphenytetrazolium(TTC)staining,immunohistochemical methods were respectively used to investigate pathological changes of brain slices,the size of cerebral infarction and nervous cell apoptotic relative proteins Bcl-2,Bax expression after treatment with ultramicro-powder of Rhizoma Gastrodiae.Results:(1)Ultramicro-powder of Rhizoma Gastrodiae could reduce the size of cerebral infarction.When the low,middle and high dose groups were compared with the ischemia group there were significant differences(P
