Abstract
Objectives : The purpose of the study is to determine the neuroprotective effects of the water and 80% EtOH extract of some herbal medicine plant on ischemia reperfusion-induced cell death in SK-N-SH human brain neuronal cells. Methods : SK-N-SH cells were treated with 3mM sodium azide and 10 mM 2-deoxy-D-glucose for 45 min, ptior to the addition of different concentrations of herbal medicine plant extract (0, 10, 25, 50, 100, 250, 500, 1000 <TEX>${\mu}g/ml$</TEX>) for 2 hr and then reperfused with growth medium, incubated for 24 h. Cell viability was determined by WST-1 assay, and ATP/ADP levels were measured by ADP/ATP ratio assay kit. Results : Herbal medicine plant extract significantly inhibited decreasing the cell viability in ischemia-induced SK-N-SH cells. Also increased the ratio of ADP/ATP in ischemia-induced neuronal cells. Conclusions : Our results suggest that herbal medicine plant extract has a neuroprotective property via increasing the energy levels in neuronal cells, suggesting that extract may has a therapeutic potential in the treatment of ischemic brain injury. The exact component and mechanism remains for the future study.
