Abstract:
Objective To explore the protective effects of butylphthalide against Aβ25-35 induced dementia-like pathological rat model and reveal the mechanism.Methods Rats were divided into five groups:control group, model group and NBP groups (10,30,and 100 mg/kg).In model group and butylphthalide groups,Aβ25-35 was injected into the lateral ventricle,while the rats in intervention group were administered with butylphthalide (gastric infusion dose of 2.5 mL/kg).Learning and memory abilities of the rats were observed with water maze test. Mitochondrial function in brain tissue was observed by ATP assay,and the mitochondrial related enzyme activities were detected by the kit.Results Water maze test showed that learning and memory abilities of model group were poorer than those of control group.They were significantly improved in NBP 10 mg/kg group and 30 mg/kg group (P <0.05),but did not change significantly in 100 mg/kg group.Compared with control group,model group had significantly decreased ATP level (P < 0.05 ); cytochrome c oxidase, pyruvate dehydrogenase complex and ketoglutarate dehydrogenase activities were also significantly decreased (P < 0.05 ).Compared with model group, butylphthalide group had significantly improved activities of mitochondrial enzymes that improved mitochondrial function.Conclusion Butylphthalide can improve learning and memory abilities of rats with Aβ25-35 -induced dementia by improving mitochondrial function.
