摘要
This study was designed to investigate whether Petroselinum crispum(PC)extract has protective effects on the brain in the scopolamine-induced Alzheimer’s disease(AD)rat model.The rats were divided into;control,scopolamine(1 mg/kg,i.p.),galantamine(1.5 mg/kg,i.p.)and PC extract(2 g/kg,p.o.)-treated scopolamine groups.On day 14,the novel object recognition test(NORT)and Morris water maze test(MWMT)were performed and then the rats were sacrificed.Scopolamine-induced cognitive impairments observed in the NORT and MWMT,significantly improved with PC extract and galantamine treatments.Scopolamine reduced M_(1) receptor expression,Bcl-2/Bax ratio,and glutathione levels in the hippocampus and frontal cortex,while malondialdehyde levels,caspase-3/9 expressions,and acetylcholinesterase(AChE)activity were found to be increased.On the other hand,PC and galantamine treatments reversed these changes.In conclusion,PC extract has shown an ameliorative effect on the spatial and recognition memory,M_(1) receptor expression,apoptosis,oxidative stress,and increased AChE activity.Thus,it was concluded that PC could prevent AD-like conditions and can be used as a functional food.However,since animal models do not completely mimic those of humans,based on the data obtained in this study,the importance of PC on human AD should be demonstrated in future studies.
