title: Effect of Ginkgo biloba leaf extract on electroencephalography of rat with cerebral ischemia and reperfusion.
abstract: OBJECTIVE
  To test the effect of Ginkgo biloba leaf extract on electroencephalography (EEG) during cerebral ischemia and reperfusion.
  
  
  METHODS
  Based on the quantitative analysis of EEG using the fast Fourier transform (FFT), the effect of Ginkgo biloba extract (GbE) on rat EEG was surveyed in the model of middle cerebral artery (MCA) occlusion and global cerebral ischemia.
  
  
  RESULTS
  In the global cerebral ischemia, GbE 8 and 16 mg/kg could accelerate the recovery of EEG after reperfusion, and GbE 4 mg/kg had the same effect but much weaker. In the MCA occlusion model, GbE 16 and 32 mg/kg greatly suppressed the drop of power spectrum of EEG.
  
  
  CONCLUSIONS
  GbE could mitigate the cerebral damage caused by ischemia.
