- 摘要：By spectrophotometry we observed the changes of ChE activities in blood of 16 cases sequelitis of poliomyelitis after acupuncture treatment. (1)Before acupuncture the ChE actiuities in the plasma of 16 cases were slightly higher than the normal level. (2)After acupuncture treatment the ChE activities of the patients were marked decreased than before(P<0.01). (3)These patients were divided into two groups:acupuncture and electro- acuputicture.Among them the ChE activites of electro-acupuncture group were statically sigificant after treatment than before(P<0.05). It is suggested that after acupuncture,especially electro-acupuncture,the decrease of ChE activities lead up to the increase of Acetyl choline at the neuro-muscular junction.So transmissive function of Ach in the bodies was increased.And finally,the patients' myatrophies were improved.More studies are needed to confirm the mechanism of acupuncture treatment for sequelae of poliomyelitis.991|0|0更新时间：2023-08-11
- 摘要：For the purpose of providing further morphological evidences to explain the gate control theory of pain mechanism the electron microseope-immunocyto- chemistry of a few structures relating to pain were studied.After unilateral transection of the dorsal roots(L1-5)of rat spinal cord,the animals were perfused through heart with 4% paraldehyde and the vibratome sections of corresponding segments of cord were treated by Sternberger's PAP technique or HRP protein A(HRP-PA)method for the demonstration of SP-and ENK- immunoreactivity(IR).Then the positive region of immunoreaction in laminae Ⅰ,Ⅱ was removed and further processed for electron microscopic observations. It was found: 1)SP-IR was present in the central nerve ending of synaptic glomerule withwhich the unlabelled dendrites and axons were synapsed to form axo(SP)- dendritic(unlabelled)axo(SP)-axonic(unlabelled),and dendro(unlabelled)- axonic(SP)contacts.These patterns of synapse may interpret that the nociceptive information transmitted via the SP containing central ending of glomerule might be transfered to many dendrites of neurons in deeper layers and would be modulated by the presynaptie dentrite. 2)The triad synaptie pattern,ie:axo(SP or ENK)-dendrite(unlabeled)- axonic(SP or ENK)might represent that different informations via different SP or ENK containing axons may converge to a common dentrite. 3)The presence of axo(ENK)-axonic(degenerated)synapse after transe- ction of dorsal roots would be regarded as the one of the important neuroan- atomic basis for the ENK presynaptic inhibition of the SP containing afferent nerve.Thus,anyway,the existance of presynaptic inhibition at the level of substantia gelatinosa could not be excluded. 4)The synapse of double ENK containing processes was also found. Because a lot of“interneuron and SG cell”as illustrated in the diagram of Melzack-Wall's gate theory were proved to be ENKnergic,the figure of axo (ENK)-axonic(ENK)synapse found in present paper might be considered as a morphological evidence of de-inhibitlon function in superficial layers of dorsal horn.1070|0|0更新时间：2023-08-11
- 摘要：Consecutive electrolytic lesion was made in the somatosensory area I of the cats.Axonal and terminal degenerations in the central lateral nucleus were observed by mean of light and electron microscope.The result showed that the somatosensory area I projects to caudal part of the central lateral nucleus via internal capsule.The fibers from synapses with neurons of the central lateral nucleus.These synapses mainly belong to the axo-dendritic and asymmetrical synapses.911|0|0更新时间：2023-08-11

- 摘要：In this experiment,we have obsevved whether the electro-acupuncture (EA)possese strenthening effects on immune function after intracerebroven- tricular(ICV)injections of dihydroxyphenylserine(DOPS)or electical stim- ulation of locus coeruleus(LC)raises the central norepinephrine(NE)levels or excites the activity of central NE-ergic neurons,respectively. The increase of EA-mediated T-lymphocyte transformation ability was suppressed and the antibods produced by B-lymphocyte system was raised after ICV injected DOPS which raise the NE levels in brain.The influenoe factors of DOPS upon the increase of EA-mediated immune function were complicated Among them,the factor in dosage-effect of DOPS may be involved in it. The ability of T-lymphpcyte transformation and lysozyme levels were markedly increased in stimulated LC group or in stimulated LC plus EA group. It showed that the immune functions could be increased when stimulating LC which can excite the abiity of central NE-(?)rgic neurons.At the sam time, the strenthening effects of immune function induc(?)d by stimulating LC may cooperated with EA.1098|0|0更新时间：2023-08-11
- 摘要：Forty-six adult,healthy,anesthetized,vagotomized rabbits were used as experimental animals in the study.In these animals,18 rabbits were paraly- zed and artificially ventilated.Integrated discharge of phrenic nerve,arttery blood pressure and End-tidal pco2 were recorded.After mechanical lesion in, or microinjection of Lidocaine(2%,2μl)into the dorso-medial region of nuc- leus facialis,(1)apneoa were induced in 16 animals;(2)decreases of respi- ratory rate and amplitude,with marked prolongation of expiratory duration, were induced in 20 animals;(3)periodic respiration were induced in 10 ani- mals.In these conditions,electroacupuncturing Renzhong point were perfo- rmed to observe the changes of repiration.The results showed that(1) breath were clicited at the same time of stimulation to animals that were in apneoa;(2)respiratory rate and amplitude were increased following stimula- tion to animals that were in low frequency respiration;(3)rhythmic breath were evoked after stimulation to animals that were in periodic respiration.On the contrary,eletroacupuncturing other points on the facial area didn't have the same effects.The study concluded that electroacupuncturing Renzhong point might have effect of respirationstarting an(?) effoct of respiration-modu- lating.643|0|0更新时间：2023-08-11

- 摘要：In present study we observed the effect of intermittent electric acupuncture on the discharge rate of heatsensitive neurons of preoptic-anterior hypothalamus (PO-AH)in the pyrogen treated rabbit. Twenty-one rabbits,weight between 1.8-2.6 Kg,were divided into two groups at random.For group A only fourty minutes after the pyrogen being injected,electroc acupuncture was put into“Dazhui”and“Duchi”points for one minute.For group B,five minutes after the pyrogen,the electric acupu- ncture was put at the sam point for one minute,alternately with fiae minutes interval,by six times,the results were summaried as follows: 1.After the pyrogen being inlected,the average firing rate of heat-sensi- tive neurons fell 71.11 per cent.the electric acupuncture was capable of reve- rsing the pyrogen action in every experiment,generally causing discharge rate to return to the control rate. 2.The intermittent electric acupuncture could markedly block the inhibitory effect of the pyrogen on heat-sensitiue neurons in the PO-AH. The results suggest that the action of electric acupuncture as well as that of the pyrogen occur within the PO-AH area.We may imagine from this fact that there may exist a specific way of the anaganism between the electric acupuncture and pyrogeu at the cellular leve,1104|0|0更新时间：2023-08-11

- 摘要：Ten full-time fetus fixed by formalin were used in this experiment.Ten pairs of anterior roots (C_6,C_7,C_8,T_5,T_(11),L_3,L_4,L_5,S_1 and S_2)were cut off from each fetus,embedded by paraffin sliced in serially longitudinal section being 10μ thick and stained by means of Nissl method.Under the light microscope,we observed and counted the neurons.The results were as follows: (1).1259 neurons in all were observed in the 198 anteriir roots of the ten fetus.One of the roots had 79 neurons being the greatest number.No neuron was observed in 38 anterior roots. (2).The neurons are often arranged singly or by threes and fives.They dipersed in all parts of the anterior root. (3).The neurons are round or oval,the nuclei are round,the nucleoli are large and distinct.Nissl bodies are slightly granular add distribute evenly. Each neuron is surrounded by a ring of capsule cells (satellite cells) which belong to sensory neurons in form. (1).The significance and originate of the appearance of neurons are ana- lysed and discussed in this article.795|0|0更新时间：2023-08-11
