The bidirectional adjustment of acupuncture means that when the physiological activities of the human body is undergoing an i mbalance state , acupuncture sti mulation of some acupoints may facili- tate the transformation of this abnormal state or nor- malize the body’s physiological performance to recov- er its original equilibriumor establish a newequilibri- um[1]. The electrical activity of neurons is one of the i mportant indexes reflectingthefunctional state of the central nervous system.… 相似文献

Experiments were carried out on rats anaesthetized with uraethane. The sponta-neous discharges and nociceptive responses of convergent neurons in the right trigerninal nucleus cau-dalis(TNC) to noxious stimuli at receptive field (cheek) were recorded extracellularly with glass mi-cro-electrode. Electroacupuncture (EA ) was applied at bilateral " Xiaguan" (ST 7 on face ) or "Zusanli" (ST 36 on shank) acupoint with Iow (2V) and high (18V) intensity. The noclceptive re-sponse of convergent neurons in TNC could be inhihited by low intensity EA applied at "Xiaguan" butnot "Zusanlil", showing the specificity of acupoints. High intensity EA at either "Xiaguan" or "Zusan-li" also reduced the nociceptive responses, showing the analgesic extensiveness of acupoints. We sug-gest that "the gate of control" mechanism plays a main role in low intensity EA and "diffuse noxiousinhibitory controls" (DNIC) rnechanism does so in high intensity EA.The results suggest that we should pay attention to the location of acupoints, 相似文献

<正> 以往我们曾在胃大部切除术病人术前、术中记录了病人指(趾)血管容积脉搏波幅的变化.在动物实验中记录了电刺激内脏大神经时腹肌肌电反应,证明了这两项生理指标对探讨內脏疼痛反应的规律和评定临床腹部手术的针麻效果上具有一定价值.本文利用胃牵拉反应的动物模型记录了腹肌 相似文献

电刺激兔耳穴对胆囊收缩的影响 总被引:2,自引:0,他引:2
本实验发现电刺激兔耳肝胆穴后,胆囊缩小,胆囊颜色变淡,其缩小反应最早在刺激后1分钟时出现,多在刺激后10分钟左右收缩开始明显,一般持续30~40分钟。取刺激后15~25分钟所得的胆囊长径和宽径乘积的平均值,与刺激前比较,差异显著。这一结果不但由体外观察到有关耳穴与肝胆脏器的相关关系。也为临床上采用耳压排石疗法提供了理论基础。 相似文献

臂带式鹰嘴钩治疗尺骨鹰嘴骨折的生物力学研究 总被引:2,自引:0,他引:2
探索臂带式鹰嘴钩治疗尺骨鹰嘴骨骨折的最佳方案,选用12具防腐配对肘关节模拟尺骨鹰嘴的三种骨折类型,测量肘关节在不同屈曲角度时骨折断端的应力,数据以SPSSV7.5.1统计软件包进行处理,以寻求不同类型骨折的最佳固定点.结果显示,三种骨折的中点组固定,骨折端应变均较远、近点组小,有显著性差异;在20~25N固定力时出现临界应力;肘关节在60°~100°之间行功能锻炼时,骨折端的应力相较屈肘90°时的应力变化范围在25%之内.表明鹰嘴钩治疗尺骨鹰嘴骨折固定点应选取在骨折块中点,固定力量在20~25N之间,肘关节功能锻炼最佳范围在屈肘60~90°之间,此时骨折端的应力符合生理压力的区间,有利于骨折愈合. 相似文献

<正> The ancient medical science of our country looks upon a human body as a monolithic whole. According to this "concept of th.e whole" the exterior(body surface)of a human body is correlated with its viscera(internal organs)through the proper channels and collaterals. There are records of such findings as the twelve channels linking with the viscera in- 相似文献

补蚀散治疗股骨头缺血性坏死临床研究 总被引:5,自引:0,他引:5
为验证外用中药制剂补蚀散对股骨头缺血性坏死的临床疗效,应用补蚀散外敷法治疗各种原因所导致的股骨头缺血性坏死患者120例156髋,应用成人股骨头缺血性坏死疗效评价法(百分法)对患者用药前和用药后6个月的临床症状和X线情况分别进行评价,并进行统计学处理。结果显示,不同病因导致的不同分期的股骨头缺血性坏死患者用药前后的分数对比,均有非常显著性差异(P<0.01),提示该药对各种原因导致的股骨头缺血性坏死均有效。治疗组与对照组总有效率对比,有显著性差异(P<0.05),提示治疗组疗效优于对照组,表明纯中药制剂补蚀散外用对于股骨头缺血性坏死有肯定的疗效。 相似文献

颈椎曲度弧顶点的分布特征 总被引:3,自引:1,他引:3
为研究采用Borden氏法测量法探讨颈椎曲度弧顶点的分布规律 ,采用Borden氏测量法在 15 4例颈椎侧位X线片上 ,测量颈椎生理曲度弧顶点的分布情况。显示 15 4例健康志愿者的颈椎曲度弧顶点位置分布的频数以C4中最多 (4 6 .1% ) ,C5中次之(18.2 % ) ,C6上最少 (仅 0 .6 % ) ;对不同弧顶点颈椎曲度值方差分析结果 :P >0 .0 5 ,差异无统计学意义。表明颈椎曲度弧顶点的分布有一定规律 ,主要分布C4中点和C5中点 ,且不同弧顶点的颈椎曲度值无明显差异。 相似文献

Alterations of proopiomelanocortin (POMC) rnRNA level in the hypothalamic arcuatenucleus were studied in rats grouped under 6h, 24h l 72h, 96h and 96h (EAX2 ) after elec-troacupuncture(EA) using rnolecular hybridization techniques. It was found that after EA, the levelof POMC mRNA rose significantly (P<0.001 ), a maximun being in the 72h group and declining inthe 96h group. In the 96h (EAX2 ) group, where EA was given at the beginning of the 72nd hour after the first one, instead of declining, the mRNA leve1 rose again. The findings may provide an expla-nation for the long postueffect of EA and its accumulation. 相似文献

浅谈历代医家对温病病因和发病的认识 总被引:2,自引:0,他引:2
作者对自《内经》到《温热论》时期温热病的病因和发病的认识进行了总结。此由最初的以“伤寒”总称各种热病,逐步发展至“外感六淫化火说”、“非时之气,戾气说”、“伏邪之说”、“新感学说”,至清代产生了“温热毒邪学说”,从病因和发病上根本区别了温病与伤寒,同时创立了卫气营血辨证、三焦辨证等理论,形成了《温热论》。 相似文献
