ABSTRACT
Objective: To study the protection and mechanisms of effective fraction from Buyang Huanwu Decoction (EFBHD) on rat brain after cerebral ischemia-reperfusion injury. Methods: Rat model of cerebral ischemia-reperfusion injury was created by the middle cerebral artery occlusion (MCAO) by modified suture method. Healthy male SD rats were randomly divided into six groups: Sham-operated group, model group, high-, middle-, and low-dose (200, 100, and 50 mg/kg) of EFBHD groups, and positive control group (treated with EGB 100 mg/kg). The neurological deficit symptom scores were observed and the infarct volume was measured by triphenyltetrazolium chloride (TTC) staining in 24 h after the cerebral ischemia. The contents of TNF-α, IL-1β, and IL-6 in serum were measured by enzyme-linked immunosorbent assay (ELISA) methods. In addition, the activity of LDH and MDA content in serum were determined by abdominal arterial blood and centrifuged. Results: Compared with the model group, EFBHD could significantly improve the neruological dysfuction, decrease the cerebral infarct volume, and inhibit the activity of LDH, and reduce the contents of MDA, TNF-α, IL-1β, and IL-6 in serum (P<0.01, 0.05). Conclusion: EFBHD has significant protection on cerebral ischemia-reperfusion injury in rats, which may be related to the inhibition of inflammatory cytokine secretion and expression and inducing the inflammation in brain tissue.
