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.

Vascular dementia (VD) is the second most common type of dementia in the elderly. Currently, there are no effective drugs for preventing or decreasing the progression of dementia. Bilobalide (BB) is a monomer extracted from Ginkgo biloba leaves. The present study investigated the neuroprotective effects of BB in a two-vessel occlusion (2-VO)-induced VD rat model. The results showed that BB (4 and 8 mg/kg) significantly protected VD rats against cognitive deficits in the Morris water maze. Biochemical assessment showed that BB (4 and 8 mg/kg) increased superoxide dismutase (SOD) activity and glutathione (GSH) content, and decreased nitric oxide synthase (NOS) activity and malondialdehyde (MDA) content. Additionally, BB (4 and 8 mg/kg) was found to alleviate neuronal apoptosis and to reduce the expression of tumor necrosis factor-α (TNF-α) in the brain cortex and the hippocampal CA1 region in VD rats. These results suggest that BB provides protection against learning and memory impairment by reducing free radical injury and inhibiting neuronal apoptosis in the brain cortex and hippocampal CA1 region in VD rats.
