Abstract:Objective:To observe the influence of osthole on neuronal apoptosis and cell cycle in Alzheimer's disease (AD) rats and to study the neuroprotective effects and its mechanism.Methods:An intracerebroventricular (i.c.v.) injection of β-amyloid peptide (Aβ25-35) was administrated to establish AD rat model. Osthole(12.5,25.0 mg·kg-1) was injected intraperitoneally to rats and cognitive functions, neuronal apoptosis and cell cycle of AD rats were observed.Results:Osthole could improve spatial learning and memory abilities of AD rats, reduce neuronal apoptosis, increase the percentage of S phase cells, promote the G2/M phase cells to divide further, strengthen the cell proliferation activity, regulate cell cycle and benefit to the maintenance of normal physiological function of neurons.Conclusion:Osthole hasneuronal protection through reducing neuronal apoptosis and regulating cell cycle, which may be one of mechanism of improving learning and memory disorder in AD rats.
