- 摘要：The spinal trigeminal nucleus of mammals has similar morphological characteristics. Its caudal partis continuous with the tip of the posterior horn of the cervical spinal cord. On the basis of the cytoar-chitecture, the spinal trigeminal nucleus may be divided into three parts: the spinal caudal, the spinalinterpolar and the spinal oral nuclei. The spinal trigeminal nucleus of the rabbit consists of the caudaland the oral parts only. The spinal caudal trigeminal nucleus is subdivided into three parts, namely,the subnucleus zonalis, the subnucleus gelatinosus and the subnucleus magnocellularis, corresponding re-spectively to the Rexed Ⅰ, Ⅱ and Ⅲ, Ⅱ layers of the posterior horn. The spinal trigeminal nucleusassociates mainly with pain and the temperature sensation of the cephalo-facial origin, and lakes part inthe processing of facial acupuncture analgesia. The spinal caudal trigeminal nucleus receives afferent fibers from the trigeminal nerve, the facialnerve, the glossopharyngeal nerve, the vague nerve, the reticular formation of the brain stem, the raphemagnus nucleus, the locus coeruleus, the cerebral cortex and the spinal cord: the efferent fibers fromthis nucleus project into the ventroposterior medial nucleus and the intralaminar nucleus of the thalmus,the medial geniculate body, the reticular formation of the brain stem, and some cranial nerve nuclei(the solitary tract nucleus, the principal sensory nucleus of the trigeminal nerve, the vestibular nucleus,the hypoglossal nucleus, the dorsal vagal nucleus, the ambiguous nucleus, the motor trigeminal nucleus,the facial nucleus and the oculomotor nucleus), and also project into non-cranial nerve nuclei (theraphe magnus nucleus, the tectum of the midbrain, periaqueductal gray matter, the cuneatus nucleus,the cuneatus lateral and the medial accessary olivary nuclei, etc) and the upper cervical spinal cord. The primary afferent fibers and the spinal caudal nucleus of the trigeminal nerve are associated with many nuclei in the central nervous system, to which the somatic or visceral afferent fibers from differentportions converge. This direct convergence may be considered as the anatomical basis for the facialacupuncture impulses acting on the somatic or the visceral pain impulses in the same portion. The fiberconnections of the spinal caudal trigeminal nucleus with the spinal cord, the gigantocellular reticularnucleus, the raphe magnus nucleus and the intralaminar nucleus of thalamus probably provide the neuralbasis for facial acupuncture analgesia and for the operations on other parts of body performed under thefacial acupuncture analgesia. The fiber connections of this nucleus with the gigantocellular nucleus, thesolitary tract nucleus and the dorso-lateral reticular formation of the medulla oblongata perhaps providethe anatomical explanation for the facial acupuncture inhibiting the visceral pain and the visceral trac-tive response, which may be very important in supporting Integument-Visera correlation theory.910|0|0更新时间：2023-08-11
- 摘要：Since Hughes separated the polypeptide with morphinelike activity from pig's brain in 1975, the re-search of the endogenous morphine like substances has made great progress. It is obvious that the subs-tances having various structures and their receptors (opiate receptors) can be divided into several subtypes.The substances exist in many tissues and organs and are widely connected with the functions of C. N. S.and endocrines. Therefore, they play an important role in physiology and pathology. Now the substanceshave become a new subject of research in numerous scientific fields as well as acupuncture analgesia. This paper gives a general statement about the recent research of the substances is designation,classification, structure speciallty, distribution and location and their receptors. Mainly discussed arethe physiological function of these substances as neurotransmitters in transmission of central impulses,regulating the sensation of pain, participating in stress reaction and addiction, and influencing theactivity of endocrines and neuropsychomotors, etc. In addition, the endogenous morphine-like substancesmay be regarded as an actual material foundation in acupuncture analgesia.735|0|0更新时间：2023-08-11

- 摘要：In order to sum up the clinical regularity of acupuncture anesthesia, serial observations on the flu-ctuation of cerebrospinal fluid pressure by means of a ventricular drainage tube were carried out duringinduction of acupuncture anesthesia or general anesthesia respectively in 18 patients with intracranialspace-occupying lesions. Recorded at the same time were the frontmastoid process rheocncephalogram andthe plethysmogram of the auricular lobule, while blood pressure at the upper arm by auscultation wasdetermined, so as to explore the possible factors that might bring an effect on the fluctuation of CSFpressure. Electro-acupuncture was applied for 20 minutes at the Jinmen and Taichong Points with the conti-nuous pulses of 80-100 Hz produced by a G-6805 electroacupuncture apparatus to induce anesthesia 0.1g of Phenobarbital and 0.3 mg of scopolamine were admin stered intramuscularly half an hour before ne-edling. General anesthesia was induced with a hyphotising doses of sodium pentothal and succinylcholi-ne (1 mg/kg body wt.). Of the acupuncture anesthesia group (6 cases) three experienced a drop in theCSF pressure, one showed no marked change while the other two had an elevated pressure of the CSF,the average being a decline of 17.0 mmH_2O. In the general anesthesia group (12 cases) all witnessed aa decrease in CSF pressure after the intra-venous administration of sodium pentothal, with an averageof 60.0 mmH_2O. While CSF pressure rose to various degrees following intra-venous administration ofsuccinylcholine, averaging 94 mmH_2O. Besides, the acupuncture anesthesia group showed an average in-crease of 3.6 mmHg of their mean arterial pressure, 2.3mm average decrease of 0.11 ohm in cerebralresistance. In the general anesthesia group, the mean arterial pressure dropped on an average by 13.9mmHg, plethysmographic wave amplitude decreased by 2.5mm (average), and cerebral resistance waslowered by an average of 0.02 obm after sodium pentothal was given i. v., but an average elevation ofmean arterial pressure by 8.1 mmHg, an average lowering of the plethysmographic wave amplitude by1.5mm and an average increase of cerebral resistance by 0.02 ohm followed the administration of suc-cinylcholine i. v., which postulate that the change in cerebral blood flow and the dilation and contractionof cerebral blood vessels are the primary causes that effect the rise or fall in CSF pressure.752|0|0更新时间：2023-08-11

- 摘要：The experimemts were performed on the rats. It was found that the development of tolerance toacupuncture analgesia could be seen by repeated electric-acupunctureandcomplete tecovery was observed24 h later under our experimental conditions. The morphine analgesia was also reduced during acupun-cture tolerance and tecovered after the acupuncture tolerance was abolished. A close correlation wasfound between them (r_s=0.33, P<0.05).814|0|0更新时间：2023-08-11

- 摘要：The sub-convulsive dose of picrotoxin (average dose 0.7mg/kg body wt., i. v.), and the stimula-tion of unilateral acupuncture points "Shenshu" "Liangqiu" raised the pain threshold of the rabbit's digital webs respectively about 30% higher than that of the control (39±7%, 34±6% respectively).While acupuncture was combined with a sub-convulsive dose of picrotoxin, the analgesic effect wasstrengthened about fourfolds more powerful than in the drug control or acupuncture alone. This wasstatistically significant. The post-effects of the combination treatment were also augmented and prolongedsignificantly. The synergism of picrotoxin with acupuncture upon analgesia suggests that r-aminobutyric acidwould play an important role in the underlying mechanism of acupuncture anesthesia, and that thismechanism is certainly not just simple inhibition.818|0|0更新时间：2023-08-11
