Water-soluble derivative of propolis mitigates scopolamine-induced learning and memory impairment in mice
چکیده انگلیسی

The water-soluble derivative of propolis (WSDP) was prepared from fresh Chinese propolis. Its major constituents were identified by high performance liquid chromatography (HPLC) analysis. It has been reported that propolis possessed a broad spectrum of biological activities but including few studies on learning and memory by now. Thus, this study was aimed to investigate the effect of WSDP on scopolamine-induced learning and memory impairment in mice. WSDP (50 mg/kg, 100 mg/kg) was given by intragastric administration (i.g.) 40 min prior to the intraperitoneal (i.p.) injection of scopolamine (1 mg/kg).The effect on amnesia was investigated with both hidden-platform acquisition training and probe trial testing in Morris water maze test. The results from 100 mg/kg WSDP group showed significant mitigation scopolamine-induced amnesia in mice. Furthermore, WSDP's effect on the acetylcholinesterase (AChE) activity in the cerebral cortex and hippocampus was also assayed. As a result, WSDP (100 mg/kg) significantly inhibited AChE activity in the hippocampus of scopolamine-treated mice. These results indicated that WSDP may mitigate amnesia in vivo through inhibition of AChE activity in the hippocampus, which suggested propolis may have potential as a pharmaceutical of brain protection with elderly population for preventing Alzheimer's disease (AD) and other neurodegenerative diseases.
