摘要:Acupuncture is known as an age-old healing art originated and developedin China,It has constituted one of the major means to protect the health ofthe people for many years,and it is regarded as important as as herb medicinein combating diseases in china,However,acupuncture suffered a serious set-back during the Ching Dynasty when acupuncture was denounced as beingharmful to the human body and was p(?)ohibited by the Manchu rulers,Althoughwidely used privately among the general population,acupuncture was not acce-
摘要:我们以前的工作提出了侧脑室注入环-磷酸腺苷(C-AMP)诱发家兔皮层的痫样电活动,同时此痫样电活动可被某些中枢递质的受体阻断剂—α、DA 受体阻断剂所阻断,表明 cAMP 的致痫作用可能与单胺类的一些递质有关。有关电针制痫方面已有不少报导,但所用致痫因素多以青霉素直接施于大脑皮层的作用。我们的实验是以侧脑室注入 cAMP 后,诱发皮层产生痫样发作波,试图观察电针双测“足三里”穴对此制痫效应。材料和方法20只成年健康家兔,体重1.8~2.5kg,雌雄不拘。在10%含水氯醛静脉麻醉下,埋藏侧脑室套管,并在相当于左、右额区In conscious rabbits,injection of cAMP (100μg in 100μl,icy) elicited high amplitude and high-frequency epileptiform seizure pattern of ECoG.The epileptic waves were inhibited by lectro-acupuncturing bilateral“Zushanli”Points.During and after the cessation of electro-acupuncture the frequency,amplitude and duration of epileptiform discharges decreascd significantly,the seizure
waves even disappeared completely.The frequency and amplitude of epileptic waves showed significant difference in comparison with those of the nonelectro acupuncture group (p<0.001 and p<0.01 respectively),the duration of epileptic waves shortened by 58.18—66.88%.
The results suggested that electroacupuncture has antiepileptic action on c-AMP induced experimental epileptic seizure.
摘要:隔核包括内侧隔核(sin)、外侧隔核(sl)、斜角带核(td),三角隔核及伞隔核等。sm、sl 及 td 是其主要部分。隔核是边缘前脑的重要结构,含有大量的胆碱能细胞、密集的脑啡肽能神经未梢和细胞体以及丰富的阿片受体,与痛觉机能有密切的关系。电刺激隔区能使动物的痛阈升高以及能提高电刺激牙髓的阈值;刺激隔区对外侧核、束旁核、中缝背核及中脑导水管周围灰质的痛诱发电位有明显的抑制作用。说明隔区参与痛觉的调节。对隔区已有许多形态学研究,但对隔区亚细胞群与脑内某些与疼痛有关区域的联系尚未见专门报道。我们采用 HRP、WGA-HRP 和 CB-HRP 法较详细地观察了与疼痛有关脑区至隔区主要亚细胞群 sm、sl、td 的传入联系。材料和方法实验用成年大鼠133只,选其中定位较准确,较局限的45只作为分析材料。用戊巴The afferent connections of septal nuclei from the brain areas relating to pain in the rat were studicd with HRP,WGA-HRP and CB-HRP methods.
Some brain areas relating to pain,for instance,locus coeruleus,raphe nuclei,periaqueductal gray,hypothalamus,lateral habenular nucleus,amygdaloid complex,hippocampus and cingulate cortex,project to medial septal nucleus,lateral nucleus and diagonal band nucleus.
The many areas relating to acupuncture analgesis project to septal nuclei,it is possible that the septal nuclei participate in regulating pain in the central nervous system.
摘要:我们曾报道,隐神经 C 类纤维传入可以到达小脑皮层,引起特异的诱发电位(C-CEP)。其易被镇痛剂吗啡抑制,可以反映慢痛。本文进一步从小脑皮层 C-CEP 作为慢痛反应指标,观察电针足三里穴对其影响,以探讨小脑皮层与电针抑制慢痛的关系。材料与方法实验用猫,体重1.5~3.0kg,雌雄不限。静脉注射1%氯醛糖(80mg/kg)麻醉。气管插管后将猫头固定在脑定位仪上。开颅,暴露小脑皮层,在左侧蚓Ⅵ小叶表面安放单极银球电极引导诱发电位,参照电极置于前额皮下,动物接地。小脑皮层表面复盖38℃石蜡油。分离右侧隐神经,在外周端结扎并剪断之,于近中段分别放置铂丝双极刺激电极、Ag-Ag(?)l 阻断电极和记录电极,Experiments were performed on cats under chloralose anaesthesia and immobilized by Flaxedil.The right saphenous nerve was stimulated with single rectangular electric pulse of 30V and A-fibers were blocked selectively by the anodal current so as to elicic the C-fiber input only.The cerebellar cortical field potential evoked by C-fiber-input (C-CEP) yeas recorded on the contrala-teral vermian Ⅵ lobule surface.
C-CEP can be inhibited obviously by injecting the morphine(0.5mg/kg)intravenously,It indicated that C-CEP had the close concern with the slow pain in ormation and might be regarded as the index of the slow pain.
The effects of the EA at the “Zusanli” point on C-CEP were observed.The results as following:
1.The amplitude of C-CEP decreased obviously after the EA at the ipsilateral “Zusanli” (strengh:10V,duration:0.2ms,frequence:5Hz).
2.From 5V—30V the more the strength of the EA was,the more the inhibitory efficiency was,
3.The inhibitory efficiency of the EA at the ipsilateral “Zusanli” point on C-CEP was stronger than at the contralateral,and the strongest at the bilateral.
摘要:脊髓灰质炎又称小儿麻痹症,属中医“痿症”,是由脊髓灰质炎病毒损害脊髓前角细胞而致的急性传染病。临床上常因无特殊和及时的治疗,留有四肢或单肢肌肉弛缓型瘫痪后遗症。我们通过应用电排针治疗脊髓灰质炎后遗症1000例的临床观察,结果基本痊癒369例,显效340例,好转260例,无效40例,总有效率为96%,发现疗效与病情,病程有明显的反比关系,与疗程成正比,与年龄关系不明显,发现疗效与主要的瘫痪肌肉有关,说明电排针治疗脊髓灰质炎确有一定疗效。为了进一步明确疗效,本研究应用肌电图检查作为脊髓灰质炎的诊断和疗效观察的客观指标,现总结如下:We observed the changes of quadriceps femoris EMG before and after treatment on treatment 41 cases of poliomyelitis sequelae with series electro-acupuncture.In 41 patients muscles strength of quedriceps femoris before
treatment in 35 cases was below 0 degree and 1 degree.The changes of EMG,Most had no motor unit potential,some only a few but duration was long,and amplitude decreased markedly.A few had fibrillation or positive sha(?)p
wave.The changes in EMG accorded with the diagnosis of poliomyelitis sequelae.
After 3 month treatment,tee EMG findings were decreasing or there was loss of fibrillation,appearance of motor unit potentials,increase of the amount of motor unit potentials,prolongation of duration and increasing of amplitude
of motor unit potentials,appearance of polyphasic potentials etc.
Through analysis of EMG,32 among 41 cases were improved,effective rate was 78%,P<0.01.EMG indices indicate the efficacy of seriesmg electro-acupuncture in treating the sequelas of poliomyelitis and confirm the clinical
therapeutic effect of the treatment.The indices indicate that the pathological changes of damaged anterior horn cells of the spinal cord were decreased and partial recovery of nervous function.The EMG changes paralleled those in
clinical therapeutic effect of treatment and changes of muscle strength.
摘要:中枢儿茶酚胺(CA)主要有去甲肾上腺素(NA)和(DA)。我们曾观察到电针后大鼠脑内 NA 和 DA 含量发生显著变化,这种效应与所用的电针频率和强度有密切关系。许多实验研究也支持 NA 和 DA参与针刺镇痛过程。此外,阿片受体拮抗剂纳洛酮广泛被用来间接检查某一生理过程是否有内源性吗啡样物质参与。大量实验表明,无论全身性或脑室注射纳洛酮可以阻断或降低针刺的效应。由于脑内多种神经化学物质在代谢和功能上有着密切的联系。在本工作中,我们观察了大鼠腹腔注射纳洛酮对电针镇痛效应及其脑内 NA 和 DA 含量变化的影响,以便探讨阿片受体在针刺镇痛中对中枢 CA 的调节作用。
摘要:晚近的心脏生理学研究表明,心脏为维持血液循环,一昼夜搏血达8吨之多,同时消耗大量的能量。其能量主要来源于冠状动脉提供的氧和代谢底物在心肌线粒体中的氧化磷酸化过程。由于心肌耗能多,使其氧储和高能磷酸键的储量均较少,因此其对能、氧缺乏十分敏感。许多研究表明,电针可以改善缺血和缺氧状态下的心脏功能,然而电针对禁食状态下心脏的影响尚未见报导,本工作主要观察了电针对禁食犬心肌游离脂肪酸摄取,心肌葡萄糖摄取及心肌氧耗量的影响。材料与方法实验对象:28只健康杂种犬被随机分为对照组和电针组,每组14只,平均体重对照(?) was observed in the study that effect of electroacupuncture (EA) on energy and oxygen metabolism of myocardium in fasting dogs.28 healthy mongrel dogs were divided into control and electroacupuncture (EA) group
randomly.All the dogs were used in the experiment after fast of 7 days,and during the fasting the dogs were fed with water.The result shows that before EA,the quantity of myocardial uptake of free fatty acid (FFA) and glucose and m(?)ocardial consumption of oxygen in control group have not marked difference from that in EA group respectively (P>0.05).
Myocardia uptake of FFA in EA group was obviously decreased than that in control group after EA on Pishu and Zhongwan points (P<0.05) and myocardial uptake of glucose in EA group was (?)nhanccd in comparson with
that in control group (P<0.05).After removing needles,myocardial upeake of FFA was reduced in contrast to that before EA in EA group with statistical significance (P<0.05).Myocardial consumption of oxygen showed a depr-
essing tendency after EA in EA group.but after removing needles,the data of myocardial consumption of oxygen had no difference from that before EA in EA group (P>0.05) and there was not different too in comparison of all
the corresponding data between the EA and contral group separately.
The result shows that the state of myocardial metabolism in fasting dogs could be improved by EA such as myocardial uptake of glucose was enhanced and myocardial uptake of FFA was reduced.
It is possible that this result is due to reduction of the depressing affect of FFA metabolism to glucose metabolism in myocardium by EA.
摘要:胃活动受交感神经和付交感神经的双重支配,其中迷走神经对胃活动的调节比较复杂,这在与胃有关迷走神经对胃电、胃血流影响的复杂性上可以表现出来。已知胃活动受迷走-迷走反射的调节。参于胃迷走-迷走反射的单纤维有不同的放电规律。本工作用引导迷走单纤维放电的方法来探讨针刺是否对胃迷走-迷走反射有影响。实验方法16 fasting cats were used to investigate the effect of acupuncture on discha(?)ge of gastric singal vagal efferent fibers (GSVEF).
1.The discharge of GSVEF may increase or decrease while artificially incrcaseing intragastrical pressure.
2.Both mannal acupuncture and electronic acupuncture could enhance or decrease GSVEA's discharge.
All results suggest that acupuncture may adjust gastric activity through affecting gastrical vago-vagal reflex.
摘要:以 Freund 氏完全佐剂形成的大鼠实验性关节炎属于Ⅲ型变态反应性疾病,炎症肢体红肿、发热、运动障碍,局部痛阈明显降低,症状持续约一个月左右逐渐消退。我们使用针刺两侧环跳穴可以提高全身痛阈,对炎症局部痛阈的提高尤为显著。但针刺提高痛阈的强度不高,镇痛持续的时间不长,所以还不能满足临床上的要求。鉴于针刺可以增加体内脑啡肽的释放,因此针刺合并使用阿片受体激动剂芬太尼与多巴胺受体拮抗剂氟哌啶可以较大地增强针刺的镇痛效果。因此本实验在此基础上进一步研究针药合并对于炎症局部慢性痛的镇痛作用,为临床治疗寻找较好的途径。方法动物模型,SD 大鼠,体重约150~200克,雌雄各半,分性别、组别饲养,水食自Our previous study demonstrated that acupuncture increased pain threshold of the body,especially in the inflammatory area.Because acupuncture can promote the release of enkephalin in the brain,it is possible that analgesic effect of acupuncture could be fdrther strengthened by administration of fentanylan opioid receptor's agonist and droperidol-dopamine receptor's agonist at same time.
In present study arthritic rats induced by freund's complete adjuvent were divided into two groups.All of them received electro-acupuncture on bilateral“Hung-Tiao” points for 15 minutes.The first group animals were also given with common dose of fenanyl 10μg/kg and droperidol 0.5mg/kg by intraperitoneal injection.Pain threshold increased very soon after needling and drugs given.The analgesic effect lasted as long as 180 minutes.There is a statistical siginficant difference between this common dose group and acupuncture control group which only kept analgesic effect 90 minutes,P<0.01.When only 1/5 dose of these druge with acupuncture was applied to arthritic rats,not only the pain threshold reached to 180+30% (P<0.01),but also the ana-
lgesic effect persisted as long as 120 minutes (P<0.01).The results from mentiond above suggested that if a small dose of drug is no effect in usual treatment,it could still play a role and reduce the pharmacological side effect by way of combining acupuncture application.
