Abstract
|
|
|
|
Epidemiologic studies have shown important relationships between oxidative stress and Alzheimer`s disease (AD) brain. In this study, free radical scavenging activity and neuronal cell protection effect of aqueous methanol extracts of Acanthopanax senticosus (A. senticosus) were examined. H2O2-induced oxidative stress was measured using 2`,7`-dichlorofluorescein diacetate (DCF-DA) assay. Pretreatment with the phenolics of A. senticosus prevented oxidative injury against H2O2 toxicity. Since oxidative stress is known to increase neuronal cell membrane breakdown, leading to cell death, lactic dehydrogenase release, and trypan blue exclusion assays were utilized. We found that phenolics of A. senticosus have neuronal cell protection effects. It suggests that the phenolics of A. senticosus inhibited H2O2-induced oxidative stress and A. senticosus may be beneficial against the oxidative stress-induced risk in AD.
