THE EFFECT OF ACUPUNCTURE ON PREVENTION AND TREATMENT OF ISCHEMIC ARRHYTHMIA AND THE RELATION BETWEEN EFFECT OF ACUPUNCTURE AND CHOLINERGIC MUSCARINE-LIKE RECEPTORS

For investigating the effect of acupuncture on ischemic arrhythmia and its mech-anism, adult albino rats with ligated anterior descending branch of coronary artery as experimentalmodel were treated with or without acupuncture, and others with imitative operation but without bothcoronary artery ligation and acupuncture treatment were used as control. It was found in acupuncturegroup that the fibrillation-liability of ischemic myocardium was efficiently decreased, the affinity ofAch-M receptors on membranes of ischemic myocardium was markedly increased, and the tolerance ofischemic myocardium to atropine was elevated in the experiment of atropine inducing fibrillation.These results indicate that acupuncture may play a therapeutic role on ischemic arrhythmia throughactivating the activity of muscarine-like receptors of cholinergic nervous system.     

EFFECT OF ACUPUNCTURE ON ELECTROMYOGRAPH OF MYOSITIS AND PATHOLOGY OF MUSCLE

An animal model of experimental polymyositis(EPM)similar to humampolymyositis(PM)was made by immuning with skeletal muscular homogenate of rabbits.We treatedthem by acupuncturing Zusanli(ST 36)and Xuehai(SP 10)for 8 consecutive weeks and comparedthem with control group.The changes of electromyogram and muscular pathology were analysed.The results show that all changes in acupuncture group are milder than that in control group and sug-gest that acupuncture has some beneficial adjustment for the immunity of PM.

ACUPUNCTURE IN RELIEF OF PAIN AND HEALING OF GANGRENE OF LIMBS

Pain and gangrene in limbs due to Buerger's disease, Raynaud's phenomenon andatherosclerosis are a great problern to manage in modern medicine. Vasodilators, sympathectomy andprogressive amputations cannot solve the problem. Electr0acupuncture shows very good results so that drugs and surgery may be spared. Total 32 cases (Buerger's 27, Raynaud's 4, atherosc1erosis 1 )were treated with acupuncture needling and electrostimulation. Acupoints used were Weizhong (BL4O ), Taixi (KI 3), Zusanli (ST 36), Jiexi (ST 41 ), Bafeng (Extra), Neiguan (PC 6), Hegu (LI4 ), Baxie (Extra) . The frequency of electrostimulation at acupoints was 100- 500 cycles per minute.Daily treatment was carried out the first 1O days, then the times of treatment reduced. The therapywas maintained once in two beths. Of 27 cases of Buerger's disease, 19 cases (82. 6 % ) were healed. Pain was relieved but uker not healed in 1 case (4. 3% ). Failure was 3 (13% ). 3/4 (75 % ) ofRaynaud's cases, pain and gungrene were fully control1ed; the oth

RESEARCH ON THE CHANGES OF THE CONCENTRATION OF IONIZED CALCIUM IN THE POINT NEIGUAN OF RABBITS WITH ACUTE HEART ISCHEMIA AFTER ELECTROACUPUNCTURE

Objective: To explore the mechanism of "Neiguan"(PC6) electroacupuncture in improving acute heart ischemia.Methods: Thirty-two healthy New Zealand rabbits were divided into 4 groups: normal group, sodium chloride group, model group and acupuncture group.Heart ischemia was induced in the rabbits by means of PPI auditive vein injection.We used the technique of microdialysis and inductively coupled plasma optical emission spectroscopy, and collected the extracellular fluid in the point Neiguan(PC6).In the mean time acupuncture of Neiguan was performed.The changes of concentration of ionized calcium in extracellular fluid of Neiguan were observed.Results: The concentrations of ionized calcium of the model group and the acupuncture group were decreased compared with the normal group(P0.05).After acupuncture the concentration of ionized calcium were increased compared with the model group(P0.05), showing that Neiguan electroacupuncture can increase the concentration of ionized calcium.Conclusion: The mechanism of Neiguan(PC6) electro-acupuncture in improving acute heart ischemia is associated with the change of concentration of ionized calcium in extracellular fluid of Neiguan(PC6).

电针猫“内关”对促进急性心肌缺血恢复作用传入途径的分析

<正> 临床和实验研究结果表明,针刺内关可以治疗多种疾病。为阐明这种效应的机制,研究针刺信息的作用途径,一些作者对针刺“内关”的传入神经通路等进行了积极的探讨。我们曾观察过电针猫“内关”区的脊髓背根诱发电位节段分布范围,分析了内关传入途径与正中神经,尺神经和桡神经的关系,认为内关传入途径与正中神经关系最密切。本文以猫颈-胸导联叠加的ST段电位值变化为急性心肌缺血性损伤的指标,以正中神经复合动作电位为神经纤维类别兴奋的指标,分析电针“内关”效应的传     

针刺内关对心肌缺血-再灌注损伤家兔CGRP和PGE2的影响

目的:对比观察电针内关与心肌缺血预处理对心肌缺血-再灌注损伤家兔心肌组织中降钙素基因相关肽(CGRP)及前列腺素E2(PGE2)的影响,以探讨针刺内关抗心肌缺血的作用机理。方法:健康家兔46只,随机分为5组,即假手术组、缺血-再灌注模型组、缺血预处理组、电针内关组、电针足三里组;结扎家兔冠脉左前降支造成心肌缺血模型,以RM46多导生理仪持续监测心电,用硝基四氮唑兰染色测量心肌梗死范围,用放射免疫法检测家兔心肌组织CGRP、PGE2含量。结果:结扎冠脉左前降支后,心梗范围扩大;除预处理组外,其余各组与假手术组比较均有显著性差异,而假手术组、预处理组和针内关组与模型组比较均有明显差异;CGRP和PGE2水平模型组明显低于假手术组、预处理及针内关组(P<0.05或P<0.01)。结论:心肌缺血预处理与电针内关对缺血-再灌注心肌均有明显的保护作用,其作用机制可能与CGRP、PGE2的参与有关。
