摘　　要：目的:针刺的不同刺激时间可以产生不同的针刺效应,故实验采用不同刺激时间电针干预运动大鼠,筛选电针运动大鼠足三里更有效的留针时间。方法:采用不同针刺留针时间干预运动大鼠,观察血清SOD、MDA及骨骼肌JNK变化,筛选更有效的留针时间。用生化法测定血清SOD、MDA,用western blot测定JNK。结果:运动后大鼠血清MDA显著升高、SOD降低,骨骼肌JNK蛋白表达升高,两种留针时间治疗后,都能降低血清MDA、升高SOD,降低JNK蛋白表达,但递增变化留针时间升高血清SOD、降低骨骼肌JNK更明显。结论:实验得出不同留针时间对针刺效应不同,留针时间递增变化对疲劳的恢复效果更好。Objective：Different acupuncture time can produce different effect. In order to select more effective acupuncture time, this experiment adopts different time to treat the exercised rats. Methods： The experiment adopts different time to select more effective one by observing the changes of SOD, MDA and JNK. Check SOD and MDA by chemistry and by checking JNK by western blot. Result： After exercising, serum MDA and JNK increase strikingly, in the same means serum SOD decreases. After acupuncture, both kinds of treatment methods can decrease MDA, .INK and increase SOD. But changing time treatment is better in increasing SOD and decreasing JNK. Conclusion： The experiment concludes that different acupuncture time surely produces different effect, changing time treatment is better in easing fatigue.
