| Pretreament with repeated electroacupuncture induced neuroprotection against spinal cord ischemiareperfusion injury in rabbits |

| 摘 要： | AIM:To investigate whether pretreatment with repeated electroacupuncture (EA) could induce ischemic tolerance against transient spinal cord ischemia in rabbits.METHODS:24male New Zealand white rabbits were randomly assigned to 3 groups(n=8 each),animals in the control group received no treatment;animals in the SP and EA group received sodium pentobarbitone 30mg/kg each day for 5 days;animals in EA group were also received electroacupuncture at the Zusanli acupoint 30min a day for 5days.24hours after the last treatment,spinal cord ischemia was induced by an infrarenal aortic occlusion for 20min.Hind-limb motor function was determined with the Tarlov criteria at 4,8,12,24 and 48h after reperfusion.All animals were sacrificed at 48h after reperfusion and the spinal cords(I5) were remoed immediately for histopathologic study.RESULTS:The neurologic outcome and histopathology(48h) in the EA group were significantly better than the control group(P=0.006).CONCLUSION:Pre-ischemic treatment with electroacupuncture significantly reduces spinal cord ischemia-reperfusion injury in rabbits.
