Abstract
|
|
|
|
Alzheimer’s disease(AD) is a progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylcholinesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APPs)’s overexpression. The present research is to examine the inhibitory effect of CWBD on PS1, PS2 and APPs’s overexpression detected by Western blotting. To verify further the effects of CWBD on cognitive deficits, we tested it on the scopolamine(1mg/kg)-induced amnesia model of the mice using the Morris water maze tests, and there were ameliorative effects on memory impairment as a protection from scopolamine. CWBD only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, whereas blood glucose level was shown to attenuate the amnesia induced by scopolamine and increased extracellular serum level. In conclusion, studies of CWBD that has been known as anti-choline and inhibitory ablilities of APPs’s overexpression could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer’s disease.
