Abstract:
Objective The purpose of this study was to investigate the protective effects of icaritin (ICT), one of the active ingredients in Epimedii Folium, on mouse model of cerebral ischemia-reperfusion (I/R) in vivo. Methods ICR mice were subjected to an 1 h transient middle cerebral artery occlusion (MCAO) and followed by 24 h of reperfusion. Neurological deficits, infarct volume, brain edema and survive rate were measured, respectively. The levels of brain IL-1β, TNF-α, ROS and DNA-binding activity of NF-κB p65 were measured by ELISA kits. The levels of malondialdehyde (MDA) and activities of superoxide dismutase (SOD) were detected by spectrophotometry, and the release of nitric oxide (NO) were detected by Griess kit. Results The results showed that ICT markedly reduced the neurological deficit scores, brain edema, infarct volume and increased the survival rate of the cerebral I/R mice. The expression of IL-1β, TNF-α, NO, MDA and DNA-binding activity of NF-κB p65 were significantly inhibited by ICT, while the activity of SOD were up-regulated at the same time. Conclusion These results suggested that ICT possessed significant neuroprotective effects in cerebral I/R mice, which might be related to prevent neuroinflammatory and oxidative damage.
