摘　　要：目的探讨捻转补泻手法与补泻效应的关系。方法雄性wistar大鼠50只,随机分为5组(A、B、C、D、E组),每组10只,A组不造模,其余各组用电击足底加噪声刺激造成应激性高血压模型,A、B组为对照组,C、D、E组分别施以针刺不做手法、针刺左侧太冲并用捻转补法和针刺左侧太冲并用捻转泻法的手法,观察施以手法即刻各组大鼠颈交感神经放电情况。结果针刺处理前B、C、D、E各组神经放电频率直方图及积分与A组比较,有较大幅度的增加,说明模型建立后,交感神经放电增加,血压升高。针刺处理后,D组分别与B、C组比较,差异显著(P<0.05),说明在施行捻转补法即刻,交感神经放电频率增加,大鼠血压升高。E组分别与B、C组比较,差异极显著(P<0.01),说明在施行捻转泻法时,交感神经放电频率减少,大鼠血压降低。结论补泻手法具有有效性,且针刺补泻手法与补泻效应之间存在正相关性。Objective To investigate the relationship between twirling reinforcement-reduction method and effect of reinforcement-reduction. Method Wistar male rats （ n = 50 ） were randomly divided into group A, B, C, D and E （ each n = 10）. Besides group A the model of stress-induced hypertension was established by foot-shock and noise stimulation is other groups. Group A and B were assigned as the control group, group C was treated with acupuncture only, group D with twirling reinforcement method in left Taichong （ LR3 ）, and group E with twirling reduction method in left Taichong （ LR3 ）. The discharge of cervical sympathetic nerve in different groups was observed at a moment of needling. Result Before acupuncture the discharge frequency histograms and integrals in group B, C, D and E greatly increased compared with those in group A, which indicated that the discharge of cervical sympathetic nerve and blood pressure increased after the model establishment. After acupuncture there was a significant difference between group D and group B or group C （P 〈 0.05）, which indicated that at the moment of using twirling reinforcement method the discharge frequency of cervical sympathetic nerve and blood pressure increased. There was a great significant difference between group E and group B or group C （P 〈0.01 ）, which indicated that at the moment of using twirling reduction method the discharge frequency of cervical sympathetic nerve and blood pressure decreased. Conclusion The twirling reinforcementreduction method is effective and correlated to twirling reinforcement-reduction effect.
