In the model of gerbil of acute global ischemia and reperfusion

we studied the effects of electroacupuncture (EA) on total power of EEG at different periods of global ischemia and reperfusion. The "Fengfu" (GV 16) and "Jinsuo" (GV 8) points were stimulated by electrical pulse with frequency 7 Hz and intensity of 5-6 mA for 30 min. Recording was made before ischemia and 0 min

15min

30min

60min

120 min and 240 min after reperfusion respetively. The results were as follows:1. In hte control group

after 10 min of ischemia

the amplitude of EEG was severely inhibited

even became flatten

and the total power of EEG was significantly decreased to 1. 41 + 1. 29% .After reperfusion

the recovery of total power was very slow. The peak level of recovery occured at 120 min following reperfusion was 27. 39+ 11. 31%.2. In comparison with the control group

the EA remarkably improved the recovery of EEG after ischemia and reperfusion. The recovery of total power was 71. 45 + 16. 46% (P<0. 01)

and 75. 27+ 18. 43 % (P<0. 01) at 120 min and 240 min after reperfusion respectively.These results strongly indicte that EA could reduce the EEG inhibition during global ischemia and improve the recovery after reperfusion
