Plasma levels of beta-endorphin and ACTH were measured during and outside migraine attacks in 17 patients with common migraine and 11 patients with classic migraine. Specific radioimmunoassays for beta-endorphin and ACTH were used. The beta-endorphin assay did not cross-react with beta......-lipotropin. In common migraine, median plasma beta-endorphin was 3.3 pmol/l (95% confidence limits: 2.5-4.0 pmol/l) during attacks and 2.9 (2.4-3.2) pmol/l in the headache-free period. In classic migraine, plasma beta-endorphin was 3.2 (1.4-4.3) pmol/l during attacks and 2.4 (1.1-3.6) pmol/l outside attacks. ACTH...

Radioimmunological evidence for beta-endorphin in human cerebrospinal fluid

Graf, M.

1982-01-01

Both-endomorphin-like immunoreactivity in human cerebrospinal fluid was determined by two different radioimmunoassays. Measurements made using a bought RIA-kit (Immuno Nuclear Corporation) produced results which were too high compared to results from the literature. The procedure for the beta-endophin radioimmunoassay of Hoellt et al. was followed, the various steps studied and in part modified. Here both beta endorphin and beta-lipotropin were labelled with I-125 and a new method introduced for separating I - -125 following labelling. Studies on the specificity of the method revealed that, in addition to beta-endorphin, beta-lipotropin and two further non-identified fluid fractions were also determined but that the specificity of the RIA's could be significantly increased by prior extraction of the fluid with silicic acid. Determinations of beta-endorphin-like immunoreactivity in 28 different human fluids using this RIA gave values from below 20 pg/ml to 70 pg/ml thus confirming literature values. (orig.) [de

Analyzing the evolution of beta-endorphin post-translational processing events: studies on reptiles.

Shoureshi, Pezhman; Baron, Andrea; Szynskie, Laura; Dores, Robert M

In many cartilaginous fishes, most ray-finned fishes, lungfishes, and amphibians, the post-translational processing of POMC includes the monobasic cleavage of beta-endorphin to yield an opioid that is eight to ten amino acids in length. The amino acid motif within the beta-endorphin sequence required for a monobasic cleavage event is -E-R-(S/G)-Q-. Mammals and birds lack this motif and as a result beta-endorphin(1-8) is a not an end-product in either group. Since both mammals and birds were derived from ancestors with reptilian origins, an analysis of beta-endorphin sequences from extant groups of reptiles should provide insights into the manner in which beta-endorphin post-translational processing mechanisms have evolved in amniotes. To this end a POMC cDNA was cloned from the pituitary of the turtle, Chrysemys scripta. The beta-endorphin sequence in this species was compared to other reptile beta-endorphin sequences (i.e., Chinese soft shell turtle and gecko) and to known bird and mammal sequences. This analysis indicated that either the loss of the arginine residue at the cleavage site (the two turtle species, chick, and human) or a substitution at the glutamine position in the consensus sequence (gecko and ostrich) would account for the loss of the monobasic cleavage reaction in that species. Since amphibians are capable of performing the beta-endorphin monobasic reaction, it would appear that the amino acid substitutions that eliminated this post-translational process event in reptilian-related tetrapods must have occurred in the ancestral amniotes.

Five adult male monkeys (Macaca mulatta) weighing 7.1-9.9 kg were given synthetic human beta-endorphin (800 micrograms) and [ 14 C]methoxy-inulin (50 microCi) in 400 microliters of normal saline intrathecally. Serial samples of cerebrospinal fluid were drawn through a previously positioned indwelling spinal catheter and were assayed for concentrations of beta-endorphin (determined by radioimmunoassay) and inulin (determined by liquid scintillation counter). Spinal fluid concentrations of beta-endorphin and inulin peaked and declined in a parallel manner. The clearance ratio (calculated from the reciprocal of the ratio of the areas under the respective curves of elimination of the two species) remained remarkably similar from animal to animal, giving a mean value of 1.060 +/- 0.090 (SEM). This ratio, being near unity, suggests that beta-endorphin is eliminated from spinal fluid in a fashion similar to that of inulin, which is removed exclusively by bulk absorption

Rats pars intermedia cells were incubated for 3 h with the following amino-acids: a) 35 S-methionine and 3 H-phenylalamine; b) 3 H-valine; and c) 3 H-valine and 3 H-lysine. Radioactive gamma-lipotropin, beta-lipotropin and beta-endorphin were purified on carboxy- methyl-cellulose and characterized by polyacrylamide disc gel electrophoresis af pH 4.5, molecular weight estimation and microsequencing. Rat gamma-lipotropin was shown to differ slightly from ovine gamma-lipotropin in its NH 2 -terminal amino acid sequence, in containing no methionine and having phenylalanine at position 6, valine at positions 13 and 27, and lysine at position 20. The same variations were observed in the sequence of rat beta-lipotropin, while rat beta-endorphin was shown to be identical to the ovine beta-endorphin. Following a 3-h pulse of rat pars distalis, the cells were extracted with care to avoid beta-lipotropin degradation by proteolytic enzymes. A peptide was purified and identified to be rat beta-endorphin, thus demonstrating that beta-endorphin is biosynthesized in pars distalis and is not an extraction artifact. (author)

Snead, O C; Stephens, H

1984-06-01

Rats ranging in postnatal age from 6 hours to 28 days were implanted with cortical and depth electrodes as well as an indwelling cannula in the lateral ventricle. We then administered varying amounts of the opiate peptides leucine-enkephalin and beta-endorphin intracerebroventricularly with continuous electroencephalographic monitoring. Leucine-enkephalin produced electrical seizure activity in rats as young as 2 days. beta-Endorphin administration was associated with seizures at the fifth postnatal day, with a high incidence of apnea resulting in death in animals as young as 6 hours. An adult seizure response to beta-endorphin and leucine-enkephalin was seen at 15 and 28 days of age, respectively. Naloxone blocked the seizure produced by these opiate peptides in all age groups. The data indicate that the opiate peptides are potent epileptogenic compounds in developing brain, that seizures induced by leucine-enkephalin differ from those caused by beta-endorphin, and that petit mal-like seizure activity can be an adult response in the rodent.

Biotinylated human. beta. -endorphins as probes for the opioid receptor

The reaction of human ..beta..-endorphin and biotinyl N-hydroxysuccinimide with or without spacer arm, afforded a series of products that were separated by high performance liquid chromatography (HPLC). Liquid secondary ion mass spectrometry of the biotinylated products and their tryptic digests produced abundant protonated molecular ions (MH/sup +/), which specified the number and location of biotinylation. Between 1 and 4 biotinyl residues were incorporated per human ..beta..-endorphin molecule, at Lys-9, -19, -24, -28, and -29, but not at the amino-terminal Try-1. Three HPLC fractions were isolated for receptor binding studies monobiotinylation of Lys-9, Lys-19, and a mixture of Lys-24, Lys-28, and Lys-29 derivatives. IC/sub 50/ values for binding to ..mu.. and delta opioid receptor sites were 3-8 times higher for monobiotinylated derivatives than for the parent human ..beta..-endorphin. Association with avidin decreased opioid receptor affinities for the C/sub 6/ spacer derivative biotinylated at position Lys-9, which is close to the (1-5) enkephalin receptor region. In contrast, avidin did not affect or even increased apparent affinities to ..mu.. and delta sites for derivatives biotinylated at the ..cap alpha..-helical part of the molecule (Lys-19, -24, -28, and -29). Biotinylated human ..beta..-endorphins also bound to low affinity nonopioid binding sites on NG-108-15 cells; however, affinities to these sites were considerably reduced when derivatives were bound to avidin. The ability of biotinylated human ..beta..-endorphin to cross-link the ..mu.. and delta opioid receptors to avidin allows application of the biotin-avidin system as a molecular probe of the opioid receptor.

beta. -endorphin augments the cytolytic activity and interferon production of natural killer cells

1986-02-01

The in vitro effects of the neurohormone ..beta..-endorphin (b-end) on natural killer (NK) activity and interferon (IFN) production mediated by large granular lymphocytes (LGL) were investigated. LGL-enriched fractions from peripheral blood mononuclear cells (PBMC) from normal human volunteers were obtained by fractionation over discontinuous Percoll gradients. LGL were preincubated with or without various concentrations of b-end or the closely related peptides ..cap alpha..-endorphin (a-end), ..gamma..-endorphin (g-end), or D-ALA/sub 2/-..beta..-endorphin (D-ALA/sub 2/-b-end), a synthetic b-end analogue. NK activity was assayed on /sup 51/Cr-labeled K562 target cells. Preincubation of LGL effectors (but not K562 targets) for 2 to 18 hr with concentrations of b-end between 10/sup -7/ M and 10/sup -10/ M produced significant augmentation of NK cytolytic activity (mean percentage increase: 63%). The classic opiate antagonist naloxone blocked the enhancing effect when used at a 100-fold molar excess relative to b-end. These findings demonstrate that b-end enhances NK activity and IFN production of purified LGL, and suggests that b-end might bind to an opioid receptor on LGL that can be blocked by naloxone. These results lend support to the concepts of regulation of the immune response by neurohormones and the functional relationship between the nervous and immune systems.

beta. -endorphin modulation of mitogen-stimulated calcium uptake by rat thymocytes

Energy Technology Data Exchange (ETDEWEB)

Hemmick, L.M.; Bidlack, J.M.

1987-10-19

Lymphocytes stimulated by mitogens or antigens exhibit an enhanced calcium uptake early in the proliferation or activation response. Modulation of this calcium uptake results in alterations of proliferation and immunocompetence. ..beta..-endorphin and other opioids affect several parameters of lymphocyte competence. Limited data are available concerning the mechanism(s) of these effects. This study examines whether a possible opioid mechanism is the modification of the early calcium influx into stimulated lymphocytes. The time course of both concanavalin A (Con A) and phytohemagglutinin (PHA)-stimulated /sup 45/Ca/sup 2 +/ uptake into thymocytes was characterized to determine the optimal time for testing the effects of opioids. BETA-Endorphin 1-31 significantly enhanced Con A-stimulated /sup 45/Ca/sup 2 +/ uptake into rat thymocytes. This peptide had no significant effect on PHA-simulated /sup 45/Ca/sup 2 +/ uptake or on basal thymocyte /sup 45/Ca/sup 2 +/ flux. The ..beta../sub h/-endorphin stimulatory effect was titratable in the range of 0.1 nM to 10 ..mu..M. Naloxone did not reverse the enhancement. Met-enkephalinamide and other opioid agonists did not duplicate the stimulatory effect. Thus, the ..beta../sub h/-endorphin 1-31 enhancement of Con A-stimulated /sup 45/Ca/sup 2 +/ uptake by rat thymocytes does not operate via classical opioid receptor mechanisms. ..beta../sub h/-endorphin 1-31 appears to be acting on a subset of T cells that are responsive to Con A but not to PHA. 30 references, 4 figures, 1 table.

Infundibular neurons of the human hypothalamus simultaneously reactive with antisera against endorphins, ACTH, MSH and beta-LPH.

In man, discrete neurons of the infundibular (arcuate) nucleus contain compounds that can be stained with anti-endorphin (alpha and beta), anti-ACTH, anti-MSH (alpha and beta) and anti-beta-LPH immune sera (I.S.). In the fetus, certain neurons stain with anti-beta-endorphin or anti((17--39)ACTH starting from the 11th week of fetal life. At the ultrastructural level, these neurons contain elementary granules that are immunoreactive with anti-beta-endorphin. In the adult, neurons immunoreactive with anti-beta-endorphin are found in the infundibular nucleus. Their axonal fibers terminate around blood vessels in the neurovascular zone and in the pituitary stalk, or establish contacts with non-immunoreactive perikarya of the infundibular nucleus. These neurons can be stained with anti(17--39)ACTH and anti-beta-endorphin I.S. The most reactive are also stained moderately with anti-alpha-MSH, anti-beta-MSH, anti-beta-LPH, anti-alpha-endorphin, or anti(1--24)ACTH I.S. These results indicate that, in man, compound(s) identical with or immunologically related to endorphins, beta-LPH, ACTH and MSH are secreted by certain hypothalamic neurons. These agents probably originate from a common precursor molecula similar to the so-called pro-opiocortin.

This paper determines the level of beta-endorphin-like immunoreactivity (beta-elir) in the blood plasma of baboons and studies its changes in certain situations. For radioimmunoassay of beta-ELIR in the blood plasma, a standard kit and the appropriate technique were used. The background plasma beta-ELIR level of the baboons, in a state of quiet wakefulness, was 0.0 = 1.0 fmoles/ml. The total level of b-ELIR was 134 plus or minus 24 pg/ml. The data show that elevation of the plasma b-ELIR level accompanies stress formation, including the development of a state of shock in baboons. A definite role in the regulation of the plasma b-endorphin level may be played by the paraventricular-perifornical region of the hypothalamus.

beta-endorphin, adrenocorticotrophin, and alpha-melanocyte stimulating hormone were measured by radioimmunoassay in three areas of human brain at necropsy in seven subjects with Wernicke-Korsakoff syndrome and in 52 controls. Thiamin concentration in six brain areas was also measured. Mamillary body beta-endorphin concentrations were significantly increased in those with the syndrome compared with controls, and those controls with high alcohol intake showed increased mamillary body beta-endorphin compared with controls with low alcohol intake. Brain thiamin concentration was similar in both groups, with the exception of the brainstem, where it was reduced in subjects with Wernicke-Korsakoff syndrome. Thalamic beta-endorphin in controls was inversely correlated with thiamin in frontal white matter, frontal cortex, parietal white matter and parietal cortex, while beta-endorphin in the hypothalamus of patients was inversely correlated with thiamin in frontal cortex, parietal white matter, thalamus and brainstem. These results suggest that there is a disturbance of the endorphinergic system in Wernicke-Korsakoff syndrome which may be related to alcohol intake. PMID:1650797

Full Text Available Abstract Background Acupuncture therapy for obstructive respiratory diseases has been effectively used in clinical practice and the acupuncture points or acupoints of Zhongfu and Tiantu are commonly-used acupoints to treat patients with the diseases. Since the impaired mucociliary clearance is among the most important features of airway inflammation in most obstructive respiratory diseases, the effect of needle puncture and electro-acupuncture at the specific acupoints on tracheal mucociliary clearance was investigated in anesthetized quails. Methods Mucociliary transport velocity on tracheal mucosa was measured through observing the optimal pathway, and fucose and protein contents in tracheal lavages were determined with biochemical methods. In the therapeutic group, needle puncture or electro-acupuncture stimulation to the acupoints was applied without or with constant current output in 2 mA and at frequency of 100 Hz for 60 minutes. In the sham group, electro-acupuncture stimulation to Liangmen was applied. Results Our present experiments demonstrated that the electro-acupuncture stimulation to Zhongfu and Tiantu significantly increased tracheal mucociliary transport velocity and decreased the content of protein in the tracheal lavage, compared with the control group. Moreover, either needle puncture or electro-acupuncture stimulation to Zhongfu and Tiantu significantly reverted the human neutrophil elastase-induced decrease in tracheal mucociliary transport velocity and human neutrophil elastase -induced increase in the contents of fucose and protein in the tracheal lavage, compared with the control group. Conclusion These results suggest that either needle puncture or electro-acupuncture stimulation to the effective acupoints significantly improves both airway mucociliary clearance and the airway surface liquid and that the improvements maybe ascribed to both the special function of the points and the substantial stimulation of electricity.

Hypoxic-ischemic encephalopathy (HIE) is a common and potentially devastating condition in the neonate, associated with high mortality and morbidity. Effective treatment options are limited and therefore alternative therapies such as acupuncture are increasingly used. Previous studies have shown that electro acupuncture promoted proliferation of neural progenitor cell and increased expression of neurotrophic factor in HIE. However, effects of electro acupuncture on downstream signaling pathways have been rarely researched. So, in the present study, we aimed to evaluate the neuroprotective effects of electro acupuncture on HIE and to further investigate the role of GDNF family receptor member RET and its key downstream PI3-K/Akt pathway in the process. A rat HIE model was constructed by the left common carotid artery (LCCA) ligation method in combination with hypoxic treatment. Considering that Baihui (GV20), Dazhui (GV14), Quchi (LI11) and Yongquan (KI1) are commonly used in clinics for stroke treatment and are easy to locate, we chose the above four acupoints as the combination for electro acupuncture treatment which was performed once a day for different time periods. Hematoxylin-eosin (HE) staining and transmission electron microscopy results showed that electro acupuncture could ameliorate neurologic damage and alleviate the degenerative changes of ultra structure of cortical neurons in rats subjected to HIE. And the longer acupuncture treatment lasted, the better its therapeutic effect would be. This was accompanied by gradually increased expression of GDNF family receptor RET at the mRNA level and its downstream signaling Akt at the protein level in the ischemic cortex. These findings suggest that electro acupuncture shows neuroprotective effects in HIE, which at least in part is attributed to activation of PI3-K/Akt signaling pathway.

Full Text Available Objectives : The purpose of this study was to compare the effect of acpuncture and electro-acupuncture of low(EA(L and high(EA(H frequency at Haegye(ST41 on intestinal hypomotility induced with loperamide in rats. Methods : We made suppressed state of intestinal motility with loperamide in rats and carried out needle retention acupuncture, low frequency electro-acupuncture and high frequency electro-acupuncture at ST41 in rats devided into pre-treatment group and post-treatment group. We fed charcoal to them after the treatment and measured the travel rate of charcoal in the gastrointestinal track to analyze which treatment is more effective in state of intestinal hypomotility. Results : None of acupuncture, EA(L and EA(H at ST41 had significant influences on intestinal motility of rat in normal state. Needle retention at ST41 did not significantly increase intestinal motility suppressed with loperamide in rats. Pre-treatment of EA(L and EA(H at ST41 significantly increased intestinal motility suppressed with loperamide in rats. Post-treatment of EA(L and EA(H at ST41 did not have significant influences on intestinal motility of rat in normal state. Conclusions : These results suggest that treatment of EA(L and EA(H at ST41 may be effective on gastric disorders such as intestinal hypomotility and its effect had more prevention than cure. Further study is necessary to know more effects of ST41 and electro-acupuncture of low and high frequency.

Full Text Available Background: Caesarean section is one of the most common interventions to overcome labor complications. However, pain cannot be avoided after the surgery. Lavender aromatherapy is considered as one of non-pharmacological therapy to reduce pain and increase beta-endorphin levels. Objective: To examine the effect of lavender aromatherapy on the intensity of pain and beta-endorphin levels in post-caesarean mothers. Methods: This was a quasy-experimental study with pretest and posttest with control group at Sembiring Delitua General Hospital on December 2016 to February 2017. There were 40 samples selected using purposive sampling, with 20 samples assigned in the experiment and control group. Numerical Rating Scale (NRS was used to measure pain and ELIZA methods to measure beta-endorphin levels. Independent t-test and paired t-test were used for data analysis Results: Results of this study showed that there was a significant difference in the mean value of pain intensity levels (p=0.000 and beta-endorphin levels (p=0.023 between experiment and control group. Conclusion: There was a significant effect of lavender aromatherapy on the decrease of pain intensity and the increase of beta-endorphin hormone in post-caesarean mothers. It is expected that lavender aromatherapy can be used as an alternative treatment to reduce pain and increase beta-endorphin levels in post-caesarean mothers.

Since numerious physiological systems display muscarinic receptor supersensitivity in major depressive illnesses, the authors have hypothesize that anterior pituitary release of ACTH and beta-Endorphin immunoreactivity may also be muscarinically supersensitive in depression. The studies were conducted under FDA-approved IND and with local human subjects committee approval. Plasma ACTH concentrations were determined as follows: samples were assayed in duplicate using equilibrium radioimmunoassay utilizing a rabbit anti-porcine ACTH antibody. Significance ofchanges in plasma cortisol, ACTH and beta-endorphin immunoreactivity after physostigmine and saline were determined by repeated measures analysis of variance. In all subject groups, physostigmine (relative to placebo) caused significant increases in plasma concentrations of cortisol, ACTH, and beta-endorphin immonoreactivity

We measured with radioimmunoassay the {beta}-endorphin-like and {alpha}-MSH-like immunoreactivities in milk and plasma of 8 lactating women. Mean {beta}-endorphin concentrations ({plus minus} SD) were 16.6 {plus minus} 6.7 fmol/ml in milk and 9.9 {plus minus} 4.1 fmol/ml in plasma. {alpha}-MSH concentrations were 39.4 {plus minus} 15.5 pg/ml in milk and 18.2 {plus minus} 8.4 pg/ml in plasma. The concentrations of both peptides in milk were significantly higher than in plasma. No significant correlation between milk and plasma concentrations of these peptides was found.

Intracerebral beta-endorphin, met-enkephalin and morphine: kindling of seizures and handling-induced potentiation of epileptiform effects.

Cain, D P; Corcoran, M E

1984-06-18

The effects of repeated infusion of small, initially subconvulsive amounts of beta-endorphin, met-enkephalin or morphine sulfate into the amygdala and hippocampus were investigated. beta-endorphin and met-enkephalin evoked epileptiform spiking when infused into the posterior amygdala or ventral hippocampus. Morphine evoked epileptiform spiking when infused into the anterior amygdala. Naloxone blocked or terminated the spiking. Repetition of the infusions led to the gradual development of bilateral generalized convulsions by beta-endorphin and met-enkephalin and to the development of tolerance to morphine. An unexpected observation was that handling, immobilization or conspecific threat potentiated the epileptiform effects of beta-endorphin and morphine in many cases. These results suggest that endogenous opiate mechanisms might play a role in convulsive seizures and that stressful stimuli can exacerbate opiate seizures.

Absorptive-mediated endocytosis of cationized albumin and a beta-endorphin-cationized albumin chimeric peptide by isolated brain capillaries. Model system of blood-brain barrier transport

Cationized albumin (pI greater than 8), unlike native albumin (pI approximately 4), enters cerebrospinal fluid (CSF) rapidly from blood. This suggests that a specific uptake mechanism for cationized albumin may exist at the brain capillary wall, i.e. the blood-brain barrier. Isolated bovine brain capillaries rapidly bound cationized [ 3 H]albumin and approximately 70% of the bound radioactivity was resistant to mild acid wash, which is assumed to represent internalized peptide. Binding was saturable and a Scatchard plot gave a maximal binding capacity (Ro) = 5.5 +/- 0.7 micrograms/mgp (79 +/- 10 pmol/mgp), and a half-saturation constant (KD) = 55 +/- 8 micrograms/ml (0.8 +/- 0.1 microM). The binding of cationized [ 3 H]albumin (pI = 8.5-9) was inhibited by protamine, protamine sulfate, and polylysine (molecular weight = 70,000) with a Ki of approximately 3 micrograms/ml for all three proteins. The use of cationized albumin in directed delivery of peptides through the blood-brain barrier was examined by coupling [ 3 H]beta-endorphin to unlabeled cationized albumin (pI = 8.5-9) using the bifunctional reagent, N-succinimidyl 3-(2-pyridyldithio)proprionate. The [ 3 H]beta-endorphin-cationized albumin chimeric peptide was rapidly bound and endocytosed by isolated bovine brain capillaries, and this was inhibited by unlabeled cationized albumin but not by unconjugated beta-endorphin or native bovine albumin. Cationized albumin provides a new tool for studying absorptive-mediated endocytosis at the brain capillary and may also provide a vehicle for directed drug delivery through the blood-brain barrier

Cationized albumin (pI greater than 8), unlike native albumin (pI approximately 4), enters cerebrospinal fluid (CSF) rapidly from blood. This suggests that a specific uptake mechanism for cationized albumin may exist at the brain capillary wall, i.e. the blood-brain barrier. Isolated bovine brain capillaries rapidly bound cationized (/sup 3/H)albumin and approximately 70% of the bound radioactivity was resistant to mild acid wash, which is assumed to represent internalized peptide. Binding was saturable and a Scatchard plot gave a maximal binding capacity (Ro) = 5.5 +/- 0.7 micrograms/mgp (79 +/- 10 pmol/mgp), and a half-saturation constant (KD) = 55 +/- 8 micrograms/ml (0.8 +/- 0.1 microM). The binding of cationized (/sup 3/H)albumin (pI = 8.5-9) was inhibited by protamine, protamine sulfate, and polylysine (molecular weight = 70,000) with a Ki of approximately 3 micrograms/ml for all three proteins. The use of cationized albumin in directed delivery of peptides through the blood-brain barrier was examined by coupling (/sup 3/H)beta-endorphin to unlabeled cationized albumin (pI = 8.5-9) using the bifunctional reagent, N-succinimidyl 3-(2-pyridyldithio)proprionate. The (/sup 3/H)beta-endorphin-cationized albumin chimeric peptide was rapidly bound and endocytosed by isolated bovine brain capillaries, and this was inhibited by unlabeled cationized albumin but not by unconjugated beta-endorphin or native bovine albumin. Cationized albumin provides a new tool for studying absorptive-mediated endocytosis at the brain capillary and may also provide a vehicle for directed drug delivery through the blood-brain barrier.

{sup {alpha}}N-acetyl human {beta}-endorphin(1-31) injected icv to mice antagonized the analgesic activity of {beta}-endorphin-(1-31) and morphine whereas the analgesia evoked by DADLE and DAGO was enhanced by this treatment. The modulatory activity of {sup {alpha}}N-acetyl {beta}-endorphin-(1-31) was exhibited at remarkable low doses (fmols) reaching a maximum that persisted even though the dose was increased 100,000 times. The regulatory effect of a single dose of the acetylated neuropeptide lasted for 24h. The activity of {sup {alpha}}N-acetyl human {beta}-endorphin(1-31) was partially retained by the shorter peptide {sup {alpha}}N-acetyl human {beta}-endorphin-(1-27) and to a lesser extent by {beta}-endorphin-(1-27), {beta}-endorphin-(1-31) lacked this regulatory activity on opioid analgesia. Acetylated {beta}-endorphin-(1-31) displayed a biphasic curve when competing with 5 pM ({sup 125}I)-Tyr{sup 27} human {beta}-endorphin-(1-31) specific binding, the first step was abolished with an apparent IC{sub 50} of 0.35 nM, and the rest with an IC{sub 50} of 200 nM. It is suggested that {sup {alpha}}N-acetyl {beta}-endorphin-(1-31) changed the efficiency of the opioid analgesics by acting upon a specific substrate that is functionally coupled to the opioid receptor, presumably the guanine nucleotide binding regulatory proteins G{sub i}/G{sub 0}.

The endogenous opioid system plays an important role in the behavioral effects of nicotine. Thus, micro-opioid receptor and the endogenous opioids derived from proenkephalin are involved in the central effects of nicotine. However, the role played by the different endogenous opioid peptides in the acute and chronic effects of nicotine remains to be fully established. Mice lacking beta-endorphin were acutely injected with nicotine at different doses to evaluate locomotor, anxiogenic and antinociceptive responses. The rewarding properties of nicotine were evaluated by using the conditioned place-preference paradigm. Mice chronically treated with nicotine were acutely injected with mecamylamine to study the behavioral expression of nicotine withdrawal. Mice lacking beta-endorphin exhibited a spontaneous hypoalgesia and hyperlocomotion and a reduction on the anxiogenic and rewarding effects induced by nicotine. Nicotine induced similar antinociception and hypolocomotion in both genotypes and no differences were found in the development of physical dependence. The dissociation between nicotine rewarding properties and physical dependence suggests a differential implication of beta-endorphin in these addictive related responses.

This prospective cohort study aimed to compare the efficiency of laser versus traditional acupuncture in treating cervical spondylosis (CS) pain. Forty female patients were randomized into two equal groups that received 3 sessions / week for 4 weeks. Group A received needle acupuncture therapy with electrical stimulation for 20 min at standard acupoints, ear points and Ashi point on the average 3 points. Group B received low level laser therapy (LLLT) acupuncture at the same acupoints. The results demonstrated that tenderness disappeared in 65% of patients in group A and 75% of patients in group B with improved percentage of 85.5% and 89.2%. Pain on VAS related to direction of motion at 6 directions was improved in all cases where with improvement percentage 76.45% and 85.88%. Pain on VAS at rest was improved in all patients with improvement percentage of 80.41% and 84.28%. NDIQ score improved in all patients with improvement percentage of 69.78% and 73.77%. Follow up of VAS after 6 months from the last session revealed persistent improvement in 55% of patients of group A vs 80% of patients of group B. Mean serum TNF-α was decreased in 85% of patients of group A vs 95% of patients of group B where serum beta endorphins was increased in all patients. It is concluded that both modes of treatment for CS gave improvement regarding pain intensity, disability and quality of life being more evident in LLLT followed for 6 months supported with improved serum TNFα and beta endorphin.

The authors studied the effect of beta-endorphin on catecholamine concentrations in the hypothalmus and cerebral cortex in rats, as a contribution to the explanation of the mechanism of action of this peptide on certain pituitary trophic functions. Concentrations of dopamine, noradrenalin, and adrenalin were determined by a radioenzymatic method. A Mark 3 scintillation system was used for radiometric investigation of the samples. The results of these experiments indicate that beta-endorphin has a marked effect on brain catecholamine levels mainly in the hypothalamus.

Full Text Available Background. Alcoholism, which is a disabling addiction disorder, is a major public health problem worldwide. The present study was designed to determine whether the application of acupuncture at the Shenmen (HT7 point suppresses voluntary alcohol consumption in addicted rats and whether this suppressive effect is potentiated by the administration of naltrexone. Methods. Rats were initially trained to self-administer a sucrose solution by operating a lever. A mechanical acupuncture instrument (MAI for objective mechanical stimulation was used on rats whose baseline response had been determined. In addition, the effect of HT7 acupuncture on beta-endorphin concentration and ethanol intake via naltrexone were investigated in different groups. Results. We found that ethanol intake and beta-endorphin level in rats being treated with the MAI at the HT7 point reduced significantly. The treatment of naltrexone at high doses reduced the ethanol intake and low-dose injection of naltrexone in conjunction with the MAI also suppressed ethanol intake. Conclusions. The results of the current study indicate that using the MAI at the HT7 point effectively reduces ethanol consumption in rats. Furthermore, the coadministration of the MAI and a low dose of naltrexone can produce some more potent reducing effect of ethanol intake than can acupuncture alone.

Moss, H B; Yao, J K

It is well-established that the secretion of the opioid neuropeptide beta-endorphin is perturbed by the administration of various drugs of abuse. Several investigators have speculated that variations in beta-endorphin secretory regulation may precede the development of a substance use disorder, and thus be a component of the liability for substance abuse. In order to test this hypothesis, we examined fasting, morning plasma concentrations of beta-endorphin and two catecholamine metabolites in prepubertal boys naive to drugs of abuse and at elevated familial risk for a substance use disorder (SA+), and in controls (SA-). Specifically, the dopaminergic metabolite homovanillic acid (pHVA), and the noradrenergic metabolite, 3-methoxy-4-hydroxy-phenylglycol (pMHPG) were measured. Between-group differences were not found for beta-endorphin, pHVA, or pMHPG. Similarly, such differences did not differentiate sons of fathers with Antisocial Personality Disorder and controls. However, regression analysis revealed that although both pHVA and pMHPG predicted beta-endorphin concentrations to similar degrees, the directions of influence were the opposite. pHVA was found to be positively associated with beta-endorphin while pMHPG was found to be negatively associated with beta-endorphin. No between-group differences in these relationships were found. The results suggest an opponent process in catecholaminergic regulation of beta-endorphin in humans, and are consistent with observations in the central nervous system of animal models.

It has been impossible to unequivocally identify which endogenous opioids modulate the incentive value of rewarding stimuli because these peptides are not highly selective for any single opioid receptor subtype. Here, we present evidence based on the measurement of instrumental behavior of beta-endorphin and enkephalin knock-out mice that both opioid peptides play a positive role. A progressive ratio schedule was used to measure how hard an animal would work for food reinforcers. The loss of either opioid reduced responding under this schedule, regardless of the palatability of the three different formulas of reinforcers used. The phenotype of mice lacking both endogenous opioids was nearly identical to the phenotype of mice mutant for either individual opioid. Responses were tested in nondeprived and deprived feeding states but were reduced in beta-endorphin- and enkephalin-deficient mice only when they were maintained under nondeprived conditions. Other operant manipulations ruled out variables that might contribute nonspecifically to this result such as differences in acquisition, early satiation, motor performance deficit, and reduced resistance to extinction. In contrast to the effects on instrumental performance, the loss of either or both endogenous opioids did not influence preference for water flavored with sucrose or saccharin in a two-bottle free-choice drinking paradigm. We conclude that both beta-endorphin and enkephalin positively contribute to the incentive-motivation to acquire food reinforcers. Because the attenuation of operant responding was observed only during a nondeprived motivational state, the hedonics of feeding are likely altered rather than energy homeostasis.

Correlation between ovarian steroidogenesis and beta-endorphin in the Lizard Uromastyx acanthinura: Immunohistochemical approach.

Full Text Available In Mammals, opioid peptides are involved in various physiological processes including the reproductive function. The knowledge of the distribution of beta-endorphin, one of opioid peptides in Reptiles ovaries is very limited. Therefore, the present study used the lizard ovarian follicles to further elucidate the role of this peptide in steroidogenesis. In Uromastyx acanthinura, the localization of both this peptide and sex steroid hormone was investigated by the immunohistochemical approach. This technique was used to evaluate the distribution of these substances and their relationship. The beta-endorphin is strongly distributed in the granulosa cells and oocyte cytoplasm of the previtellogenic follicles in sexually quiescent lizards (winter when steroidogenesis was interrupted. In spring, the signal became weak, or even absent, in the vitellogenic and previtellogenic follicles. The granulosa cells of the previtellogenic follicles showed an important synthesis of 17beta-estradiol. Females that did not undergo in vitellogenesis in spring showed the same profile than quiescent females of winter. These findings represent the first evidence of the presence of beta-endorphin in the ovary of this lizard. The seasonal variations observed in the reproductive cycle suggest that this opioid peptide is involved in the modulation of seasonal steroidogenesis.

Skin β-endorphin mediates addiction to UV light.

UV light is an established carcinogen, yet evidence suggests that UV-seeking behavior has addictive features. Following UV exposure, epidermal keratinocytes synthesize proopiomelanocortin (POMC) that is processed to melanocyte-stimulating hormone, inducing tanning. We show that, in rodents, another POMC-derived peptide, β-endorphin, is coordinately synthesized in skin, elevating plasma levels after low-dose UV. Increases in pain-related thresholds are observed and reversed by pharmacologic opioid antagonism. Opioid blockade also elicits withdrawal signs after chronic UV exposure. This effect was sufficient to guide operant behavioral choices to avoidance of opioid withdrawal (conditioned place aversion). These UV-induced nociceptive and behavioral effects were absent in β-endorphin knockout mice and in mice lacking p53-mediated POMC induction in epidermal keratinocytes. Although primordial UV addiction, mediated by the hedonic action of β-endorphin and anhedonic effects of withdrawal, may theoretically have enhanced evolutionary vitamin D biosynthesis, it now may contribute to the relentless rise in skin cancer incidence in humans.

The purpose of the present study was to examine the effect of altering the concentration of 5-hydroxytryptamine (5-HT) on beta-endorphin (beta-Ep) content in the hypothalamus, thalamus, and periaqueductal gray (PAG)-rostral pons regions of the rat brain. The selective 5-HT reuptake inhibitor, fluoxetine (10 mg/kg), significantly lowered beta-Ep content in the hypothalamus and the PAG. Parachlorophenylalanine, which inhibits 5-HT synthesis, significantly elevated beta-Ep in all brain parts studied. Intracisternal injections of the neurotoxin 5-prime, 7-prime-dihydroxytryptamine with desmethylimipramine pretreatment significantly increased beta-Ep content in the hypothalamus and the PAG. In adrenalectomized rats, fluoxetine significantly decreased beta-Ep levels in the hypothalamus and increased the levels in the PAG. The results indicate that 5-HT may modulate the levels of brain beta-Ep.

With an antiserum against human ..beta..-endorphin (..beta..-EP) crossreacting <2% with human ..beta..-lipotropin (..beta..-LPH) by weight we have developed a radioimmunoassay that can detect 1 pg ..beta..-EP in diluted raw plasma. In a.m. fasting plasma of 14 normal subjects ..beta..-EP ranged from <5 to 45 pg/ml. ..beta..-EP was elevated in untreated, but normal in successfully treated Cushing's disease; undetectable in a patient with adrenal adenoma; extremely high in Nelson's syndrome; and elevated in a patient with bronchogenic carcinoma before, but undetectable after tumor resection. In subjects with intact hypothalamic-pituitary-adrenal axis, ..beta..-EP was undectectable after dexamethasone and increased after metyrapone administration and insulin-induced hypoglycemia. ..beta..-EP concentration was considerably lower in serum than in simultaneously collected plasma, but increased in serum left unfrozen for several hours after clot removal. Thus, ..beta..-EP behaves like a hormone responding to the same stimuli as ACTH and ..beta..-LPH and blood appears to contain enzymes both generating and destroying immunoreactive ..beta..-EP.

Full Text Available This study was performed in order to investigate possible role of brain beta-endorphins as markers of antidepressive drugs therapy monitoring. Experiment was done using amitriptyline and trazodone as antidepressants. For quantification of brain beta-endorphins we used RIA technique. Our results showed significant decrease of brain beta-endorphins concentration in drug-pretreated animals, vs. those in of control group treated with 0,95% NaCl. The lower values were obtained in trazodone pre-treated animals. This study shows that use of psychoactive drugs have influence on brain beta-endorphins concentration. beta-endorphins could be of great importance, used as markers for evaluation of patient treatment.

Effects of chronic ethanol treatment on the in vitro biosynthesis of pro-opiomelanocortin and its posttranslational processing to beta-endorphin in the intermediate lobe of the rat pituitary

Chronic treatment of rats with 15% (vol/vol) ethanol in tap water as their only source of liquid over a period of 3 weeks resulted in a strong decrease by almost 50% in tissue levels and in vitro release of immunoreactive beta-endorphin of the neurointermediate pituitary. Moreover, the in vitro incorporation of (3H)phenylalanine into peptides of the neurointermediate pituitary, immunoprecipitable with beta-endorphin antiserum, was found to be decreased by more than 30%. Analysis of beta-endorphin-related peptides on sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed that chronic ethanol treatment reduced the in vitro biosynthesis of the beta-endorphin precursor pro-opiomelanocortin. This ethanol-induced effect was combined with a retardation in the time course of the posttranslational processing of the precursor into beta-endorphin. Thus, chronic ethanol treatment may influence the activity of enzymes which process the opioid peptide precursor pro-opiomelanocortin, leading to a decreased formation of the final secretory product beta-endorphin.

Beta-endorphin in the plasma: Radioimmunological determination and findings in patients showing disorders at the level of the hypothalamus-pituitary-adrenal axis

International Nuclear Information System (INIS)

Hoerl, A.

1985-01-01

Beta-endorphin and adrenocorticotropic hormone (ACTH) were determined simultaneously in the plasma using a radioimmunological procedure. It was found that in patients showing imbalances within the hypothalamus-pituitary-adrenal system (Addison's disease, Cushing's Syndrome, Nelson's Syndrome) as well as elevated levels of beta-endorphin the values of ACHT invariably were also increased. The behaviour of the plasma levels of beta-endorphin and ACTH before, during and subsequent to hypophyseal surgery gives evidence to prove the close link between the two hormones. Tests performed to examine the function of the corticotropin releasing factor (CRF) both in healthy volunteers and patients suffering from endocrinological disorders likewise pointed to a parallel behaviour pattern of the two hormones in their responding or failure to respond to stimulation. The fact that a significant correlation was established between all measured values of beta-endorphin and ACTH is further evidence in confirmation of a parallel release of these two hormones in man.

1987-04-01

In 9 women with polycystic ovarian disease (PCOD) and in 11 control subjects at the follicular phase of the normal cycle, blood samples were collected at 15-min intervals during a 2 h period of bed rest for the assay of beta-endorphin, beta-lipotropin, corticotropin, cortisol and prolactin. During the study period, the plasma levels of these hormones decreased more significantly in the PCOD than in the control group, suggesting that the PCOD patients had a more significant stress response to the puncture of the vein than the control subjects. The second hour of the study period was considered to represent resting levels of hormones. The mean resting levels (+/- S.E.) of the hormones between the PCOD and control groups, respectively, were as follows: beta-E, 2.0 +/- 0.4 vs. 1.1 +/- 0.1 pmol/l, p less than 0.05; beta-LPH, 3.4 +/- 0.6 vs. 2.1 +/- 0.5 pmol/l, N.S.; corticotropin, 2.0 +/- 0.3 vs. 1.1 +/- 0.5 pmol/l, p less than 0.05; cortisol, 176 +/- 24 vs. 128 +/- 16, N.S.; and prolactin; 3.9 +/- 0.6 vs. 5.6 +/- 1.2 ng/ml, N.S. These results confirm the previous findings on increased circulating levels of beta-E in PCOD. A concomitant increase of the plasma level of corticotropin suggests that the basal secretion of both beta-E and corticotropin from the anterior pituitary gland is increased in women with PCOD.

Differential effects of whole-body {gamma}-irradiation on antinociception induced by morphine and {beta}-endorphin administered intracerebroventricularly in the mouse

Two separate lines of evidence suggested the present study. First, intracerebroventricularly (i.c.v.) administered morphine (a {mu}-opioid receptor agonist) and {beta}-endorphin (an {epsilon}-opioid receptor agonist) produce antinociception by activating different descending pain inhibitory systems. Second, {gamma}-irradiation attenuates the acute antinociceptive action of i.c.v. injected morphine, but not DPLPE (a {delta}-opioid receptor agonist), in mice. These findings prompted us to investigate the effect of {gamma}-irradiation on the antinociception produced by i.c.v. injected morphine and {beta}-endorphin in male ICR mice. In one group, mice were exposed to whole-body irradiation at a dose of 5 Gy from a {sup 60}Co {gamma}-source and the antinociceptive effects were tested 5, 30, 60,90 and 180 min after irradiation using the 1% acetic acid-induced writhing test (10 ml/kg). The antinociceptive effect was produced time-dependently and reached its maximum at 90 min after irradiation. Thus, time was fixed in the following studies. In another group, mice were irradiated with 5 Gy and tested 90 minutes later for antinociception produced by i.c.v. administration of morphine (50 and 100 ng/mouse) or {beta}-endorphin (31 ng/mouse). Irradiation significantly potentiated the antinociception produced by {beta}-endorphin. However, the antinociception produced by morphine was not affected by irradiation. These results demonstrate a differential sensitivity of {mu}- and {epsilon}-opioid receptors to {gamma}-irradiation, in addition, support the hypothesis that morphine and {beta}-endorphin administered supraspinally produce antinociception by different neuronal mechanisms.

The properties of (/sup 125/I)beta h-endorphin-binding sites from rat brain membranes and membranes from the NG108-15 cell line were compared using a monoclonal antibody directed against the opioid receptor and opioid peptides as probes. The binding of (/sup 125/I)beta h-endorphin to both rat brain and NG108-15 membranes yielded linear Scatchard plots with Kd values of 1.2 nM and 1.5 nM, respectively, and Bmax values of 865 fmol/mg rat brain membrane protein and 1077 fmol/mg NG108-15 membrane protein. A monoclonal antibody, OR-689.2.4, capable of inhibiting mu and delta binding but not kappa binding to rat brain membranes, noncompetitively inhibited the binding of 1 nM (/sup 125/I)beta h-endorphin to rat brain and NG108-15 membranes with an IC50 value of 405 nM for rat brain membranes and 543 nM for NG108-15 membranes. The monoclonal antibody also inhibited the binding of 3 nM (/sup 3/H) (D-penicillamine2, D-penicillamine5) enkephalin to NG108-15 membranes with an IC50 value of 370 nM. In addition to blocking the binding of (/sup 125/I)beta h-endorphin to brain membranes, the antibody also displaced (/sup 125/I)beta h-endorphin from membranes. Site-specific opioid peptides had large variations in their IC50 values depending on whether they were inhibiting (/sup 125/I)beta h-endorphin binding to rat brain or the NG108-15 membranes. When the peptides were tested with the monoclonal antibody for their combined ability to inhibit (/sup 125/I)beta h-endorphin binding to both membrane preparations, the peptides and antibody blocked binding as though they were acting at allosterically coupled sites, not two totally independent sites. These studies suggest that mu-, delta-, and beta-endorphin-binding sites share some sequence homology with the 35,000-dalton protein that the antibody is directed against.

Effect of acute ethanol on beta-endorphin secretion from rat fetal hypothalamic neurons in primary cultures

Energy Technology Data Exchange (ETDEWEB)

Sarkar, D.K.; Minami, S. (Washington State Univ., Pullman (USA))

1990-01-01

To characterize the effect of ethanol on the hypothalamic {beta}-endorphin-containing neurons, rat fetal hypothalamic neurons were maintained in primary culture, and the secretion of {beta}-endorphin ({beta}-EP) was determined after ethanol challenges. Constant exposure to ethanol at doses of 6-50 mM produced a dose-dependent increase in basal secretion of {beta}-EP from these cultured cells. These doses of ethanol did not produce any significant effect on cell viability, DNA or protein content. The stimulated secretion of {beta}-EP following constant ethanol exposure is short-lasting. However, intermittent ethanol exposures maintained the ethanol stimulatory action on {beta}-EP secretion for a longer time. The magnitude of the {beta}-EP response to 50 mM ethanol is similar to that of the {beta}-EP response to 56 mM of potassium. Ethanol-stimulated {beta}-EP secretion required extracellular calcium and was blocked by a calcium channel blocker; a sodium channel blocker did not affect ethanol-stimulated secretion. These results suggest that the neuron culture system is a useful model for studying the cellular mechanisms involved in the ethanol-regulated hypothalamic opioid secretion.

The purpose of the present studies was to investigate the activity of the adrenal gland and the pituitary {beta}-endorphin system in individuals from families with a 3 generation history of alcoholism, High Risk group, or from families without history of alcoholism, Low Risk group. On the day of testing, blood sample was taken at 9:00 a.m., then the subject drank a placebo drink or an ethanol solution. Additional blood samples were taken at 15, 45 and 120 minutes post-drink. Results indicated that individuals of the High Risk group had lower basal levels of {beta}-endorphin like immunoreactivity ({beta}-EPLIR) than individuals of the Low Risk group. The dose of 0.5 g ethanol/kg B.Wt. induced an induce an increase in the plasma content of {beta}-EPLIR of the High Risk group, but not of the Low Risk group. In the Low Risk group ethanol did not induce an increase above the 9:00 a.m. levels, however, it attenuated the {beta}-endorphin decrease overtime, observed following the placebo drink. Analysis of {beta}-endorphin-like peptides in the plasma of the High Risk group, with Sephadex G-75 chromatography indicated that the major component of the plasma {beta}-EPLIR was {beta}-lipotropin. Plasma cortisol levels, following ethanol intake, presented a small increase in the High Risk group but not in the Low Risk group.

The aim of this study was to evaluate the effects of Vernonia cinerea Less. (VC) supplementation and exercise on oxidative stress biomarkers, beta-endorphin release, and the rate of cigarette smoking. Volunteer smokers were randomly divided into four groups: group 1: VC supplement; group 2: exercise with VC supplement; group 3: exercise; and group 4: control. VC was prepared by wash and dry techniques and taken orally before smoking, matching the frequency of strenuous exercise (three times weekly). Before and after a two month period, exhaled carbon monoxide (CO), blood oxidative stress (malondialdehyde [MDA], nitric oxide [NOx], protein hydroperoxide [PrOOH] and total antioxidant capacity [TAC]), beta-endorphin and smoking rate were measured, and statistically analyzed. In Group 1, MDA, PrOOH, and NOx significantly decreased, whereas TAC increased (p 0.05). In Group 3, MDA, PrOOH, NOx, TAC, and beta-endorphin levels increased significantly (p stress variables or beta-endorphine levels (p > 0.05). All groups had lower levels of CO after the intervention. The smoking rate for light cigarette decreased in group 2(62.7%), 1(59.52%), 3 (53.57%) and 4(14.04%), whereas in self-rolled cigarettes it decreased in group 1 (54.47%), 3 (42.30%), 2 (40%) and 4 (9.2%). Supplementation with Vernonia cinerea Less and exercise provided benefit related to reduced smoking rate, which may be related to oxidaive stress and beta-endorphine levels.

We examined the effects of the thiol agent cysteamine (CSH), which is known to deplete the hypothalamus of immunoreactive somatostatin, on physiological TSH and beta- endorphin secretion in the adult male rat. CSH at doses of 90 and 300 mg/kg CSH produced a rapid decline in plasma TSH, whereas a dose of 30 mg/kg did not alter plasma TSH levels. After the higher doses of CSH, TSH levels in the blood remained lower than control values on day 2, but returned to normal by 1 week. This decrease in TSH within the plasma was not associated with a reduction in hypothalamic TRH concentrations. The TSH response to 500 ng/kg TRH was normal in CSH-treated animals. Blockade of norepinephrine synthesis with diethyldithiocarbamate (500 mg/kg) or fusaric acid (100 mg/kg) inhibited TSH secretion in a manner similar to that of CSH. beta-Endorphin-like immunoreactivity (bet-End-LI) was elevated in the plasma immediately after CSH (300 mg/kg) administration. This was associated with a 58% reduction in anterior pituitary beta-End-LI and no change in hypothalmic beta-End-LI. Plasma beta-End-LI returned to normal on day 2. The increase in plasma beta-End-LI induced by immobilization stress was not compromised by CSH treatment. The observed effects of CSH on both TSH and beta-End-LI are consistent with a reduction in central norepinephrine neurotransmission through the known actin of CSH to inhibit dopamine-beta-hydroxylase. Acute stress may play a role as well in the observed changes in TSH and beta-End-LI secretion.

5 ..mu..g of human ..beta..-endorphin were labelled with 2 mCi /sup 125/I by the chloramine T technique. After two gel filtrations on Sephadex G-15 and on Sephadex G-50 in phosphate buffer with EDTA, Trasylol and mercapto-ethanol, a pure tracer was obtained with a specific activity about 150 ..mu..Ci/..mu..g.Kept at + 4/sup 0/C, the tracer remained utilizable for 30 days without loss of immunoreactivity. The labelling with lactoperoxydase and the use of another gel filtration method (filtration on Aca 202) gave a /sup 125/I ..beta..-END tracer with the same immunoreactivity. The binding of this tracer to the antibody of an anti-..beta..-END antiserum diluted at 1/8000 was 32% with a non specific binding of 2%. 5 ..mu..g of human ..beta..-lipotropin were labelled with 0.5 mCi /sup 125/I by the lactoperoxydase method. After two gel filtrations on Sephadex G-25 and on Sephadex G-75 in phosphate buffer with EDTA, Trasylol and mercapto-ethanol, a pure tracer with a specific activity of 140 ..mu..Ci/..mu..g was obtained. It remained utilizable for 30 days when kept at + 4/sup 0/C. Gel filtration on Aca 202 did not give good purification, while gel filtration on Aca 54 was good but slower than on Sephadex G-75. The binding to antibody in absence of unlabelled ..beta..-LPH was 32% for an anti-..beta..-LPH antiserum diluted at 1/4000. The non specific binding was 2.5%.

In the present study, the immunomodulatory effect of {beta}-endorphin ({beta}-E) and shorter pro-opiomelancortin (POMC) fragments was evaluated by assessing their influence on respiratory burst in human polymorphonuclear leukocytes (PMN). The effect of the peptides on phorbol myristate acetate (PMA)-stimulated production of reactive oxygen metabolites was measured in a lucigenin-enhanced chemiluminescence (CL) assay. Both POMC peptides with opiate-like activity and their non-opioid derivatives were tested. With the exception of {alpha}-E, PMA-stimulated respiratory burst was suppressed by all POMC fragments tested. A U-shaped dose-response relation was observed. Doses lower than 10{sup {minus}17}M and higher than 10{sup {minus}8}M were without effect. {beta}-E and dT{beta}E both suppressed PMA-induced oxidative burst in human PMN at physiological concentrations. {gamma}-E and dT{gamma}E proved to be less potent inhibitors, reaching maximal effect at higher concentrations. DE{gamma}E exerted an even less pronounced but still significant suppressive effect at the concentration of 10{sup {minus}10}M. None of the endorphins tested was shown to affect resting oxidative metabolism in the PMN. The modulatory effects of the opioid peptides could not be blocked by the opioid antagonist naloxone.

To assess functional relations between changes in ACTH, beta-endorphin (BE), and corticosterone (CS) levels, plasma concentrations of these hormones were studied in rats during the development of prolonged immobilization stress. Plasma hormone concentrations were determined by radioimmunoassay. The results were analyzed by standard statistical methods on a microcomputer. A particular feature about the kit used to determine BE was the presence of 50% cross-reactivity of the antiserum against beta-lipotrophin. To determine CS a highly specific antiserum produced by a laboratory was used.

Water soluble peptides are normally not transported through the blood-brain barrier (BBB). Chimeric peptides may be transportable through the BBB and are formed by the covalent coupling of a nontransportable peptide to a transportable peptide vector, e.g. cationized albumin, using disulfide-based coupling reagents such as N-succinimidyl 3-[2-pyridyldithio(propionate)] (SPDP). The transcytosis of peptide into brain parenchyma, as opposed to vascular sequestration of blood-borne peptide, was quantified using an internal carotid artery perfusion/capillary depletion method. It is shown that [125I]beta-endorphin is not transported through the BBB, but is rapidly cleaved to free [125I] tyrosine via capillary peptidase. Therefore, chimeric peptide was prepared using [125I] [D-Ala2]beta-endorphin (DABE), owing to the resistance of this analogue to peptidase degradation. The [125I] DABE-cationized albumin chimeric peptide is shown to enter brain parenchyma at a rate comparable to that reported previously for unconjugated cationized albumin. When the [125I] DABE-cationized albumin chimeric peptide was incubated with rat brain homogenate at 37 C, the free [125I] DABE was liberated from the cationized albumin conjugate prior to its subsequent degradation into free [125I] tyrosine. Approximately 50% of the chimeric peptide was cleaved within 60 sec of incubation at 37 C. These studies demonstrate that (1) [125I]beta-endorphin is not transported through the BBB in its unconjugated form, (2) a [125I] DABE-cationized albumin chimeric peptide is transported through the BBB into brain parenchyma at a rate comparable to the unconjugated cationized albumin, and (3) brain contains the necessary disulfide reductases for rapid cleavage of the chimeric peptide into free beta-endorphin and this cleavage occurs before degradation of the [125I] DABE into [125I] tyrosine

(VC supplementation and exercise on oxidative stress biomarkers, beta-endorphin release, and the rate of cigarette smoking. Methods Volunteer smokers were randomly divided into four groups: group 1: VC supplement; group 2: exercise with VC supplement; group 3: exercise; and group 4: control. VC was prepared by wash and dry techniques and taken orally before smoking, matching the frequency of strenuous exercise (three times weekly. Before and after a two month period, exhaled carbon monoxide (CO, blood oxidative stress (malondialdehyde [MDA], nitric oxide [NOx], protein hydroperoxide [PrOOH] and total antioxidant capacity [TAC], beta-endorphin and smoking rate were measured, and statistically analyzed. Results In Group 1, MDA, PrOOH, and NOx significantly decreased, whereas TAC increased (p 0.05. In Group 3, MDA, PrOOH, NOx, TAC, and beta-endorphin levels increased significantly (p 0.05. All groups had lower levels of CO after the intervention. The smoking rate for light cigarette decreased in group 2(62.7%, 1(59.52%, 3 (53.57% and 4(14.04%, whereas in self-rolled cigarettes it decreased in group 1 (54.47%, 3 (42.30%, 2 (40% and 4 (9.2%. Conclusion Supplementation with Vernonia cinerea Less and exercise provided benefit related to reduced smoking rate, which may be related to oxidaive stress and beta-endorphine levels.

The plasma beta-endorphin (beta-EP) and beta-lipotropin (beta-LPH) response of men, eumenorrheic women, and amenorrheic women (n = 6) to 1 h of rest or to a bicycle ergometer test [20 min at 30% maximum O2 uptake (VO2max), 20 min at 60% VO2max, and at 90% VO2max to exhaustion] was studied in both normal (22 degrees C) and cold (5 degrees C) environments. beta-EP and beta-LPH was measured by radioimmunoassay in venous samples collected every 20 min during rest or after each exercise bout. Exhaustive exercise at ambient temperature (Ta) 22 degrees C induced significant increases in plasma beta-EP and beta-LPH in all subjects as did work at 60% VO2max in amenorrheic and eumenorrheic women. During work at Ta 5 degrees C, the relative increase in beta-EP and beta-LPH was suppressed in eumenorrheic women and completely prevented in amenorrheic women. Although significant lowering of beta-EP and beta-LPH was observed in men and eumenorrheic women during rest at 5 degrees C, amenorrheic women maintained precold exposure levels. These findings suggest that plasma beta-EP and beta-LPH may reflect a thermoregulatory response to heat load. There appears to be a sexual dimorphism in exercise- and cold-induced release of beta-EP and beta-LPH and amenorrhea may be accompanied by alterations in these responses.

The concentrations of ..cap alpha..-, ..beta..- and ..gamma..-endorphin were determined by radioimmunoassay in HPLC fractionated extracts of post mortem hypothalamic tissue obtained from schizophrenic patients and controls. The hypothalamic concentration of ..cap alpha..- and ..gamma..-endorphin was significantly higher in patients than in controls. No difference was found in the concentration of ..beta..-endorphin, the putative precursor of ..cap alpha..- and ..gamma..-endorphins. These results suggest a deviant metabolism of ..beta..-endorphin in the brain of schizophrenic patients. Whether this phenomenon is related to the psychopathology, or is a consequence of ante mortem farmacotherapy, remains to be established.

Objective: To evaluate the change of D 2 receptors and its relationship with DA content in experimental hemi-parkinsonism rats before and after electron-acupuncture treatment. Methods: 125 I-IBZM D 2 receptor cerebral autoradiographic analysis, HPLC-ECD DA and its metabolites, homovanillic acid (HVA), 3,4-di-hydroxyphenylacetic acid (DOPAC) content detection were used to study in striatum in before treatment, electro-acupuncture treatment and treatment control group. Results: 1) The DA, HVA and DOPAC level in striatum of lesioned side in electro-acupuncture group was increased comparing with the before treatment and treatment control group (P 125 I-IBZM uptake ratio was 8.04 +- 0.71, (29.34 +- 4.83)% more than that of the contralateral side, but no significant difference was observed as compared with that of the pretreatment group [(8.09 +- 0.52), P>0.05]; however it was much lower than that of the treatment control group (8.61 +- 0.63), P 2 receptors' up regulation in rats with experimental hemi-parkinsonism

The expression of the proopiomelanocortin (POMC) gene by normal lung and thyroid was examined by measurement of the content of ACTH, beta-lipotropin (beta LPH), and beta-endorphin (beta EP) in porcine lung and thyroid tissue. Acid extracts of normal porcine lung and thyroid tissue each contained appreciable amounts of immunoreactive (ir) ACTH, ir-beta LPH, and ir-beta EP. The content of ir-beta LPH in both tissues exceeded by severalfold, on a molar basis, the content of ir-ACTH and ir-beta EP, suggesting that the common precursor POMC was processed predominantly to peptides other than ir-ACTH and ir-beta EP. A porcine thyroid extract (Calcitare, porcine calcitonin, Armour) showed equivalent levels of beta EP-like immunoreactivity and bioactivity, measured by opiate radioreceptor assay; in contrast, ACTH-like bioactivity, measured by rat zona fasciculata steroidogenesis, was only 4% of ACTH-like immunoreactivity. On reversed phase high performance liquid chromatography, Calcitare showed multiple peaks of ACTH-like immunoreactivity, one of which coeluted with porcine ACTH-(1-39), and two much smaller peaks of beta EP-like immunoreactivity, of which the smaller coeluted with porcine beta EP. These data suggest that both lung and thyroid gland synthesize POMC, which in normal tissue is usually predominantly processed to species other than ACTH and beta EP. Ectopic secretion of ACTH and beta EP by lung and thyroid neoplasms may thus represent the loss of a system(s) normally responsible for processing the precursor beyond ACTH and beta EP.

Previous work demonstrated that newborn rat anterior pituitary corticotropes display processing patterns for pro-ACTH/endorphin that are different from the adult. The synthesis and release of beta-endorphin-related peptides was examined in dispersed cell and explant cultures of newborn anterior pituitary to investigate corticotrope development further. The temporal pattern of pro-ACTH/endorphin processing differed significantly from adult rat melanotropes and AtT-20 cells. While pro-ACTH/endorphin processing begins within 30 min of synthesis in adult melanotropes and AtT-20 cells, pulse-labeling of newborn corticotropes in culture indicated that pro-ACTH/endorphin remained uncleaved for at least 90 min after synthesis. With further incubation, there was a decrease in radioactivity associated with the precursor and an equivalent rise in the radioactivity associated with beta-endorphin and beta-lipotropin. However, unprocessed precursor still remained in the cultured newborn anterior pituitary cells after a 25-h chase. Although intact pro-ACTH/endorphin from newborn corticotropes was very long-lived, the precursor did undergo oligosaccharide maturation and became endoglycosidase H resistant within 1 h after synthesis. Similar to the adult, pro-ACTH/endorphin synthesis was doubled in cultures of newborn anterior pituitary chronically treated with 10 nM CRF resulting in a 3- to 4-fold stimulation of secretion over the basal rate. However, unlike the AtT-20 cell or adult rat corticotrope, the proteolytic processing of pro-ACTH/endorphin in the newborn corticotrope was altered by chronic secretagogue treatment; less pro-ACTH/endorphin was converted to beta-endorphin in secretagogue-treated corticotropes than in controls. Thus processing of pro-ACTH/endorphin in the corticotrope is not mature by birth and can be regulated by chronic CRF treatment.

Secondary structure determination of human. beta. -endorphin by /sup 1/H NMR spectroscopy

Lichtarge, O.; Jardetzky, O.; Li, C.H.

1987-09-08

The /sup 1/H NMR spectra of human ..beta..-endorphin indicate that the peptide exists in random-coil form in aqueous solution but becomes helical in mixed solvent. Thermal denaturation NMR experiments show that in water there is no transition between 24 and 75/sup 0/C, while a slow noncooperative thermal unfolding is observed in a 60% methanol-40% water mixed solvent in the same temperature range. These findings are consistent with circular dichroism studies by other workers concluding that ..beta..-endorphin is a random coil in water but that it forms 50% ..cap alpha..-helix or more in mixed solvents. The peptide in the mixed water-methanol solvent was further studied by correlated spectroscopy (COSY) and nuclear Overhauser effect spectroscopy (NOESY) experiments. These allow a complete set of assignments to be made and establish two distinct stretches over which the solvent induces formation of ..cap alpha..-helices: the first occurs between Tyr-1 and Thr-12 and the second between Leu-14 and extending to Lys-28. There is evidence that the latter is capped by a turn occurring between Lys-28 and Glu-31. These helices form at the enkephalin receptor binding site, which is at the amino terminus, and at the morphine receptor binding site, located at the carboxyl terminus. The findings suggest that these two receptors may specifically recognize ..cap alpha..-helices.

Anti-inflammatory actions of acupuncture

Full Text Available Acupuncture has a beneficial effect when treating many diseases and painful conditions, and therefore is thought to be useful as a complementary therapy or to replace generally accepted pharmacological intervention. The attributive effect of acupuncture has been investigated in inflammatory diseases, including asthma, rhinitis, inflammatory bowel disease, rheumatoid arthritis, epicondylitis, complex regional pain syndrome type 1 and vasculitis. Large randomised trials demonstrating the immediate and sustained effect of acupuncture are missing. Mechanisms underlying the ascribed immunosuppressive actions of acupuncture are reviewed in this communication. The acupuncture-controlled release of neuropeptides from nerve endings and subsequent vasodilative and anti-inflammatory effects through calcitonine gene-related peptide is hypothesised. The complex interactions with substance P, the analgesic contribution of β-endorphin and the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines tumour necrosis factor-α and interleukin-10 are discussed.

A simple, rapid and reliable procedure is described to simultaneously concentrated and purify {beta}-endorphin, leu-and met-enkephalins from small volumes of human and rat plasma before radioimmunoassay is performed. It uses C{sub 18} Sep-Pak reverse phase cartridges. The effectiveness of different protease inhibitors in preventing degradation of opiates by plasma and different solvent systems for eluting opiates is also evaluated.

Both endorphins excess and deficiency were postulated. CGRP is probably involved in dopaminergic transmission. The aim of this study was the evaluation of beta-endorphin (BE and CGRP blood concentrations before and after treatment of severe schizophrenia. Methods: Seventy patients treated with various antipsychotics, with severe symptoms of schizophrenia (51 with positive symptoms, 19 with negative symptoms, 15 first-degree relatives, and 44 healthy controls were included in the study. BE and CGRP blood concentrations were measured during patients severe schizophrenia and in their stable mental state after treatment. The results were compared with relatives and controls. Results: BE and CGRP concentrations in patients with negative symptoms were higher than in relatives and in controls. BE levels in patients with positive symptoms were lower than in patients with negative symptoms (P<0.0000 and controls (P<0.0006. No significant changes in CGRP concentration were found in patient samples. CGRP levels in these samples were independent of treatment, but they were significantly higher than in relatives and controls. After the treatment, BE level decreased in patients with negative symptoms (P<0.0001 and increased in patients with positive symptoms (P<0.0000. No differences in BE concentration between patients in stable mental state, their relatives, and controls were found. Conclusion: Effective antipsychotic treatment results in “normalization” of BE level. Specific changes in BE concentration could be involved in dopaminergic transmission and related to some symptoms of schizophrenia. Keywords

Full Text Available The aim of our study was to establish the extent of influence of different psychotropic drugs to brain β-endorphins in experimental animals. The study was performed on albino Wistar rats (weight 250 g, treated with different psychoactive drugs. RIA technique was employed for quantification of brain β-endorphins. Brain β-endorphins were higher in experiment group treated with trazodone (929 pg/g ± 44,43; X±SD, and dibenzepine (906,63 pg/g ± 74,06, yet with lower brain content in rats treated with diazepame (841,55 pg/g ± 68,47, compared to brain β-endorphins content of control group treated with saline solution (0,95% NaCl (873,5 pg/g ± 44,89. Significant differences were obtained comparing brain β-endorphins of trazodone vs. diaze-pame treated animals, with diazepame group having lower values (p<0,02. This study showed differences in changes of rat brain β-endorphins contents when different psy-choactive drugs are used. Therefore, we consider that β-endorphins could be used for evaluation of effects of psychoactive drugs, as a useful parameter in therapy with these psycho pharmaceuticals.

Endorphin mediation of post-ictal effects of kindled seizures in rats.

Brief electrical stimulation of the enkephalin-rich globus pallidus at 1-h intervals produced kindled, clonic seizures in rats as rapidly as similar stimulation of the amygdala. Massing the kindling trials at 10-min intervals inhibited the occurrence of subsequent seizures, especially following globus pallidus stimulation. Naloxone (20 mg/kg), an opiate receptor antagonist, reversed this post-ictal inhibition of seizures following massed trials, but had no effect on seizures kindled at 1-h intervals. Thus, endorphin-released during seizures do not appear to mediate the production of kindled seizures, but do appear to mediate the transient posts ictal inhibition of seizures.

A role for beta-endorphin (beta-END) in the pathophysiology of major depressive disorder (MDD) is suggested by both animal research and studies examining clinical populations. The major etiological theories of depression include brain regions and neural systems that interact with opioid systems and beta-END. Recent preclinical data have demonstrated multiple roles for beta-END in the regulation of complex homeostatic and behavioural processes that are affected during a depressive episode. Additionally, beta-END inputs to regulatory pathways involving feeding behaviours, motivation, and specific types of motor activity have important implications in defining the biological foundations for specific depressive symptoms. Early research linking beta-END to MDD did so in the context of the hypothalamic-pituitary-adrenal (HPA) axis activity, where it was suggested that HPA axis dysregulation may account for depressive symptoms in some individuals. The primary aims of this paper are to use both preclinical and clinical research (a) to critically review data that explores potential roles for beta-END in the pathophysiology of MDD and (b) to highlight gaps in the literature that limit further development of etiological theories of depression and testable hypotheses. In addition to examining methodological and theoretical challenges of past clinical studies, we summarize studies that have investigated basal beta-END levels in MDD and that have used challenge tests to examine beta-END responses to a variety of experimental paradigms. A brief description of the synthesis, location in the CNS and behavioural pharmacology of this neuropeptide is also provided to frame this discussion. Given the lack of clinical improvement observed with currently available antidepressants in a significant proportion of depressed individuals, it is imperative that novel mechanisms be investigated for antidepressant potential. We conclude that the renewed interest in elucidating the role of beta

To determine plasma clearance kinetics for {beta}-endorphin (BE) by empirical compartmental analysis, a bolus of radioactive labeled 125I-BE was rapidly injected into a carotid artery catheter of unanesthetized lean (L) and obese (O) Zucker rats. The plasma disappearance of 125I was followed over a 3-h period. A 3-component exponential equation provided the best fit for plasma data. Plasma transit times were very short (10 s); however, plasma fractional catabolic rate was much slower. Plasma mean residence time was similar for both groups (50 min) as was recycle time (1.3 min). These data suggest that BE plasma disappearance kinetics are similar in L and O rats.

Full Text Available Background: Wet cupping therapy is a complementary therapy in pain management. The mechanism of this therapy, however, needs further elucidation. Cells injured by wet cupping therapy seem to stimulate the expression of heat shock protein 70 (HSP70. Its benefit in pain reduction could be mediated by the expression of ß-endorphin. This study aimed at determining the correlation between HSP70 and ß-endorphin after wet cupping therapy. Methods: Sixteen male Wistar rats were divided into control (CG; n=8 and treatment (TG; n=8 groups. The rats in both groups were injected with complete Freund’s adjuvant (CFA at the footpad. In the TG, wet cupping therapy was done at the left and right paralumbar regions 48 hours after the CFA injection. Twenty-four hours after therapy, the hot plate test was done to assess pain threshold. Thereafter, immunohistochemistry from the skin subjected to wet cupping therapy was conducted for HSP70 and ß-endorphin. Results: The expression of HSP70 was significantly higher in the keratinocytes of the TG (20.25±3.53; P<0.001 than in the keratinocytes of the CG (10.50±2.44; P<0.001. The expression of ß-endorphin was significantly higher in the keratinocytes of the TG (22.37±3.52; P<0.001 than in the keratinocytes of the CG (5.12±1.72; P<0.001. The results also revealed a high correlation between HSP70 and ß-endorphin (β=0.864; P<0.001. Pain threshold after wet cupping therapy was significantly higher in the TG (22.81±6.34 s; P=0.003 than in the CG (11.78±3.56 s. Conclusions: The benefit of wet cupping therapy in terms of pain reduction in rats could be mediated by the expression of HSP70 and ß-endorphin.

Full Text Available Introduction. This sports-science-related article heavily relies on studies that have reported an increase in beta-endorphin (â-EP concentration in plasma in response to physical activity. It examines the psychological and physiological effects of physical activity and exercise and reports on a research-experiment-based, endorphin-hypotheses-related pilot study aimed at exploring mood-related â-EP effects occurring in physically active male and female individuals aged 45-55 in response to physical load. Material and methods. Six 45 to 55-year-old individuals (3 males and 3 females rated as exhibiting moderate and high levels of physical activity in sport's laboratory. International Physical Activity Questionnaire (IPAQ was used to establish physical activity level. For facial expression analysis a short interview was applied, using software “FaceReader 3.0” (FR. As a load test a veloergometer exercise test was used, and Beta-endorphin (â-EP levels were measured from venous blood. Results. The findings demonstrated an increase in â-EP levels in 50% of the subjects. No positive relation between â-EP increase and happiness has been observed. In four subjects an increase in disgust was observed due to the laboratory conditions. Five minutes after the load test FR data recorded the reduction or disappearance of negative emotions for all research subjects. Conclusions. Further investigation into the relationship of plasma levels of â-EP and the emotional state of the individual involved in physical activities is needed. This necessitates a further insight into how exercise-elevated endorphins (â-EP affect mood state outside laboratory conditions. Therefore, a further investigation of people involved in physical recreation activities outdoors is envisaged.

Influences of β-endorphins in Ethanol Consumption Patterns and Acquisition of a Conditioned Taste Aversion Mediated by the Drug

Full Text Available Rewarding effects of ethanol may be mediated in part by endogenous opioids. Ethanol alters β-endorphin synthesis and release. β-endorphin heterozygous (HT and knockout (KO mice consume higher levels of a low-concentrated alcohol solution and show heightened predisposition to self-administer ethanol in comparison with wild-type (WT mice (Grisel et al., 1999. This study was conducted in order to: i re-analyze and extend previous results in terms of ethanol consumption profiles of β-endorphin deficient mice; and ii analyze conditioned aversive learning mediated by ethanol postabsorptive effects as a function of genetic capabilities to synthesize β-endorphin. In Experiment 1, mice were evaluated in terms of consumption of a low (7% ethanol solution in a two-bottle free choice paradigm. Ethanol concentration was then increased to 10 % and voluntary intake consumption was tested. WT mice displayed significantly higher consumption levels and ethanol-preference scores than did KO mice, independently from ethanol concentration. HT mice drank more ethanol than did KO mice. In Experiment 2, mice (KO, HT and WT were tested in a conditioned taste aversion paradigm in which a sodium chloride (NaCl solution was paired with a 2-g/kg ethanol dose. Only HT and KO displayed a conditioned aversion when using 2-g/kg ethanol as unconditioned stimulus. The present results indicate that total or partial deficiency of β-endorphin synthesis reduces ethanol preference and consumption. Furthermore, this study indicates that the lack of β-endorphin synthesis exacerbates ethanol’s aversive postabsorptive effects which can in turn modulate self-administration patterns of the drug.

Anterior cingulate cortex is crucial for contra- but not ipsi-lateral electro-acupuncture in the formalin-induced inflammatory pain model of rats

Full Text Available Abstract Acupuncture and electro-acupuncture (EA are now widely used to treat disorders like pain. We and others have shown previously that current frequency, intensity and treatment duration all significantly influence the anti-nociceptive effects of EA. There is evidence that stimulating sites also affect the antinociception, with EA applied ipsilaterally to the pain site being more effective under some pain states but contralateral EA under others. It was recently reported that local adenosine A1 receptors were responsible for ipsilateral acupuncture, but what mechanisms specifically mediate the anti-nociceptive effects of contralateral acupuncture or EA remains unclear. In the present study, we applied 100 Hz EA on the ipsi- or contra-lateral side of rats with inflammatory pain induced by intra-plantar injection of formalin, and reported distinct anti-nociceptive effects and mechanisms between them. Both ipsi- and contra-lateral EA reduced the paw lifting time in the second phase of the formalin test and attenuated formalin-induced conditioned place aversion. Contralateral EA had an additional effect of reducing paw licking time, suggesting a supraspinal mechanism. Lesions of rostral anterior cingulate cortex (ACC completely abolished the anti-nociceptive effects of contra- but not ipsi-lateral EA. These findings were not lateralized effects, since injection of formalin into the left or right hind paws produced similar results. Overall, these results demonstrated distinct anti-nociceptive effects and mechanisms between different stimulating sides and implied the necessity of finding the best stimulating protocols for different pain states.

To establish the possible role of hyperinsulinemia in the elevation of plasma beta-endorphin (beta-EP) levels observed in obese patients after an oral glucose load. Oral glucose tolerance test (OGTT) and euglycemic-hyperinsulinemic clamp. Two groups of six (age: 22-39 y, BMI: 30-48 kg/m2) and eight obese men (age: 18-37 y, BMI: 35-45 kg/m2), respectively, and five normal weight healthy men (age: 22-30 y, BMI 22-23 kg/m2). Glucose, insulin and beta-EP levels at baseline and every 30 min until 180 min during the OGTT; glucose, insulin, C-peptide and beta-EP concentrations at baseline and in steady state condition (i.e. during the last 30 min of insulin infusion) in the euglycemic-hyperinsulinemic clamp studies. In the six obese patients undergoing the OGTT a significant elevation of beta-EP plasma levels was observed between 60 and 90 min after glucose ingestion. In the clamp studies no significant differences in beta-EP plasma levels, blood glucose and serum insulin were observed between obese and normal weight subjects both at baseline and at steady state. A markedly diminished insulin sensitivity along with a lower inhibition of C-peptide during insulin infusion was observed in obese patients compared to control subjects. A rise in serum insulin levels unaccompanied by a concomitant increase in blood glucose concentration is unable to elicit a beta-EP response in obese patients.

Full Text Available BACKGROUND: β-endorphin plays a role in the descending pain control in the central nervous system. Central sensitization may be involved in the generating and maintenance of osteoarthritis (OA pain. However, the correlation between β-endorphin and pain severity in OA has shown conflicting results. The aim of this study was to investigate the association between plasma β-endorphin and the severity of the disease. METHODS: This study was an observational cross-sectional study carried out on 60 female subjects with knee OA who fulfilled the inclusion criteria. Plasma β-endorphin was measured by a commercial enzyme-linked immunosorbent assay (ELISA kit. Osteoarthritis knees were classified by the Kellegren-Lawrence (KL grading (1-4 criteria. The Western Ontario McMaster University Osteoarthritis (WOMAC scoring method was used to assess self-reported physical function, pain and stiffness. RESULTS: The mean of the participants' ages was 58 years old, ranging from 42 to 83 years. Overall, more than 70% of the participants were overweight with a mean of body mass index (BMI of 27.59. More than 54% of the participants were diagnosed of having KL grading 3 or 4. Plasma β-endorphin was correlated inversely with the WOMAC subscale of stiffness (r=-0.286, p=0.0311, but no correlation was noted with the WOMAC subscale of pain and physical activity. There was no significant difference of the mean of plasma β-endorphin among the KL gradings. CONCLUSIONS: Plasma β-endorphin is associated with better WOMAC total score and stiffness subscale, but not associated with KL grading of OA.

Female rats were treated with 10 microg of beta-endorphin on the 19th day of pregnancy. Offspring were studied when five months old. Serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) content in four brain regions were determined by HPLC-EC and the nocistatin levels of blood plasma using RIA methods. In each brain region studied, the 5-HT levels were highly significantly reduced and that of 5-HIAA in three regions was highly significantly increased. When 5HIAA/5HT ratios, as a measure of serotonin turnover, were calculated, imprinted animals showed extremely high values. Plasma nocistatin level was also significantly elevated. The results call attention to the effect of perinatal endorphin imprinting and its long-term consequences (e.g., setting of aggressiveness, pain tolerance).

Acupuncture has been widely used in China for three millennia as an art of healing. Yet, its physiology is not yet understood. The current interest in acupuncture started in 1971. Soon afterward, extensive research led to the concept of neural signaling with possible involvement of opioid peptides, glutamate, adenosine and identifying responsive parts in the central nervous system. In the last decade scientists began investigating the subject with anatomical and molecular imaging. It was found that mechanical movements of the needle, ignored in the past, appear to be central to the method and intracellular calcium ions may play a pivotal role. In this review, we trace the technique of clinical treatment from the first written record about 2,200 years ago to the modern time. The ancient texts have been used to introduce the concepts of yin, yang, qi, de qi, and meridians, the traditional foundation of acupuncture. We explore the sequence of the physiological process, from the turning of the needle, the mechanical wave activation of calcium ion channel to beta-endorphin secretion. By using modern terminology to re-interpret the ancient texts, we have found that the 2nd century B.C.: physiologists were meticulous investigators and their explanation fits well with the mechanistic model derived from magnetic resonance imaging (MRI) and confocal microscopy. In conclusion, the ancient model appears to have withstood the test of time surprisingly well confirming the popular axiom that the old wine is better than the new.

Mediation of Endogenous β-Endorphin in the Plasma Glucose-Lowering Action of Herbal Products Observed in Type 1-Like Diabetic Rats

2011-01-01

Full Text Available Recently, there have been advances in the development of new substances effective in managing diabetic disorders. Opioid receptors couple multiple systems to result in various biological effects, although opioids are best known for analgesia. In the present review, we used our recent data to describe the advance in plasma glucose-lowering action of herbal products, especially the mediation of β-endorphin in glucose homeostasis of insulin-deficient diabetes. In type 1-like streptozotocin-induced diabetic rats, we identified many products purified from herbs that show a dose-dependent plasma glucose-lowering action. Increase in β-endorphin secretion from the adrenal gland may activate peripheral opioid μ-receptors (MOR to enhance the expression of muscle glucose transporters and/or to reduce hepatic gluconeogenesis at the gene level, thereby leading to improved glucose utilization in peripheral tissues for amelioration of severe hyperglycemia. It has also been observed that stimulation of α1-adrenoceptors (α1-ARs in the adrenal gland by some herbal products is responsible for the increase in β-endorphin secretion via a phospholipase C-protein kinase dependent pathway. However, an increase in β-endorphin secretion from the adrenal gland by herbal products can function via another receptor. New insights into the mediation of endogenous β-endorphin activation of peripheral MOR by herbal products for regulation of glucose homeostasis without the presence of insulin have been established. Therefore, an increase in β-endorphin secretion and/or direct stimulation of peripheral MOR via an insulin-independent action might serve as the potential target for development of a therapeutic agent or promising adjuvant in intensive plasma glucose control.

The authors studied the effect of beta-endorphin on catecholamine concentrations in the hypothalmus and cerebral cortex in rats, as a contribution to the explanation of the mechanism of action of this peptide on certain pituitary trophic functions. Concentrations of dopamine, noradrenalin, and adrenalin were determined by a radioenzymatic method. A Mark 3 scintillation system was used for radiometric investigation of the samples. The results of these experiments indicate that beta-endorphin has a marked effect on brain catecholamine levels mainly in the hypothalamus

This note describes the technical details of a cerebrospinal fluid (CSF) B-Endorphin (B-End) radioimmunoassay (RIA). We used an antiserum raised in rabbits against human B-End which cross-reacs 100% with B-Lipotrophin (B-Lph). Thus, filtration chromatography is used to separate both peptides. The assay is sensitive (limit detection=14 pmoles/l), reproducible (the intra and inter assay coefficients of variation are 5 and 6% respectively). Specificity studies are performed to verify the cross-reactions with other opioid peptides and the non specific reactions with the biological fluid (CSF). In order to evaluate the effects of iodine-containing contrast media on the RIA, additional standard curves were analyzed in the presence of varying concentrations of two contrast materials.

Differential trace labeling of calmodulin: investigation of binding sites and conformational states by individual lysine reactivities. Effects of beta-endorphin, trifluoperazine, and ethylene glycol bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid

The CaS -dependent association of beta-endorphin and trifluoperazine with porcine testis calmodulin, as well as the effects of removing CaS by ethylene glycol bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA) treatment, were investigated by the procedure of differential kinetic labeling. This technique permitted determination of the relative rates of acylation of each of the epsilon-amino groups of the seven lysyl residues on calmodulin by (TH)acetic anhydride under the different conditions. In all cases, less than 0.52 mol of lysyl residue/mol of calmodulin was modified, thus ensuring that the labeling pattern reflects the microenvironments of these groups in the native protein. Lysines 75 and 94 were found to be the most reactive amino groups in CaS -saturated calmodulin. In the presence of CaS and under conditions where beta-endorphin and calmodulin were present at a molar ratio of 2.5:1, the amino groups of lysines 75 and 148 were significantly reduced in reactivity compared to calmodulin alone. At equimolar concentrations of peptides and proteins, essentially the same result was obtained except that the magnitudes of the perturbation of these two lysines were less pronounced. With trifluoperazine, at a molar ratio to calmodulin of 2.5:1, significant perturbations of lysines 75 and 148, as well as Lys 77, were also found. These results further substantiate previous observations of a commonality between phenothiazine and peptide binding sites on calmodulin. Lastly, an intriguing difference in CaS -mediated reactivities between lysines 75 and 77 of calmodulin is demonstrated. In the CaS -saturated form of the protein, both lysines are part of the long connecting helix between the two homologous halves of the protein.

Beta-endorphin (β-END) is an opioid neuropeptide which has an important role in the development of hypotheses concerning the non-synaptic or paracrine communication of brain messages. This kind of communication between neurons has been designated volume transmission (VT) to differentiate it clearly from synaptic communication. VT occurs over short as well as long distances via the extracellular space in the brain, as well as via the cerebrospinal fluid (CSF) flowing through the ventricular spaces inside the brain and the arachnoid space surrounding the central nervous system (CNS). To understand how β-END can have specific behavioral effects, we use the notion behavioral state, inspired by the concept of machine state, coming from Turing (Proc London Math Soc, Series 2,42:230-265, 1937). In section 1.4 the sequential organization of male rat behavior is explained showing that an animal is not free to switch into another state at any given moment. Funneling-constraints restrict the number of possible behavioral transitions in specific phases while at other moments in the sequence the transition to other behavioral states is almost completely open. The effects of β-END on behaviors like food intake and sexual behavior, and the mechanisms involved in reward, meditation and pain control are discussed in detail. The effects on the sequential organization of behavior and on state transitions dominate the description of these effects.

Endorphins, Exercise, and Addictions: A Review of Exercise Dependence

Directory of Open Access Journals (Sweden)

Andrea Leuenberger

2006-01-01

Full Text Available Endorphins are endogenous opioids released from the pituitary gland that are believed to mediate analgesia, induce euphoria, and play a role in the reward system in the brain. It has been suggested that endorphins are responsible for creating the relaxed psychological state known as runners high. Studies examining the relationship between vigorous exercise and blood plasma endorphin levels have produced conflicting results. Some indicate a significant increase of endorphins during or after exercise while others do not. Inconsistent methods and experimental techniques have made it difficult to determine a relationship between exercise and endorphin elevations. Research has shown that opioidergic activity plays a role in addictions by mediating the development of reinforcing qualities of certain activities and substances. A newly-established condition known as exercise dependence defines exercise as an addiction, characterized by a compulsion to exercise excessively even when the consequences are harmful to an individuals health, family relationships, and personal wealth (Griffiths, 1997; Hausenblas and Downs, 2002; Loumidis and Wells, 1998. Various surveys and questionnaires have been validated for determining the level of an individuals dependence on and need for exercise. As researchers define a clear relationship between vigorous exercise and increased endorphin levels, causes of exercise dependence can be more concretely determined. Exercise dependence is not currently recognized by the DSM-IV, but its presence in certain human behaviors (similar to those of alcoholics and drug addicts indicate that it should be precisely defined.

The influence of PMH on the level of beta-endorphin and some hormones of blood and adrenal glands was studied. The dose A (10 mkg/kg) and dose W (100 mkg/kg) of PMH were used in our experiments. Earlier it has been discovered, that PMH in such doses stimulated the processes of cell division in 24 hours since the moment of injection. The stimulation was dose-dependent. Within 24 hours PMH in A dose decreased the concentration of beta-endorphin in the blood 2.7-fold, ad in dose W increased it 2 times. The level of corticosterone in blood and adrenal glands after the injection of PMH in dose A exceeded the control data trustworthy in 4 and 24 hours since the moment of injection. In dose B in 4 hours 1.5-fold reduction of corticosterone concentration took place in the blood. Increase in epinephrine level in adrenal glands was observed after PMH administration in two doses. Content of T3 increased in 4 hours after PMH injection in dose B. The role of hormonal changes in stimulating cell division accompanied by PMH injection is discussed. The data received show that PMH influences directly proliferative processes.

In a study with coronary patients it was estimated that music is able to lower stress and fear and contributing to relaxation in spite of physical exercise. 15 patients (13 male, two female, mean age 62,2 +/- 7,6 years) of a coronary sport unit were listening to an especially composed relaxation music while training their common heart-frequency adapted exercises. Before the exercises and after listening to music blood pressures were measured and blood was collected for determination of beta-endorphin. Simultaneous to blood collection the participants had to perform two psychometric test: the perceived stress experience questionnaire (PSQ) of Levenstein to measure the graduation of subjective perceived stress and the state-anxiety inquiry (STAI) of Spielberger as an indicator of coping. To practice the trial ("test trial"), the whole protocol was performed one week prior to the mean trial, but without listening to music and without blood collections and blood pressure measurements. In the test trial without music there were no significant changes in PSQ-data. In the mean trial, under the influence of music, values in the section "worries" decreased as a sign of lower worries (26.6 versus 27.6; p = 0.039). STAI-values were significantly lower as a sign of reduced fear after listening to music (31 versus 34; p = 0.045). beta-endorphin concentration (10.91 microg/l versus 15.96 microg/l, p = 0.044) and systolic blood pressure (130 mmHg versus 140 mmHg; p = 0.007) decreased significantly after listening to music. Regarding worries and fear, patients seemed to benefit by the intervention of music. beta-endorphin was lowered significantly after music despite physical activity.

Binding of immunoreactive radioiodinated human ..beta..-endorphin (/sup 125/I-..beta..-EP) to rat serum was demonstrated by gel filtration of /sup 125/I-..beta..-EP in pooled rat serum on Sephadex G-200. Two radioactive peaks associated with proteins eluted from the column. The first peak eluted at the void volume containing lipoproteins, ..cap alpha../sub 2/- and ..beta../sub 2/-macroglobulins, and the second peak at the fraction of albumin. Binding of /sup 125/I-..beta..-EP to albumin was directly proved by gel filtration of /sup 125/I-..beta..-EP in buffer containing 4% human serum albumin on Sephadex G-200. Equilibrium dialysis was not applicable to investigating the interaction of /sup 125/I-..beta..-EP with serum proteins, because of the intense nonspecific adsorption to the semi-permeable membrane and the degradation of the peptide during dialysis. Therefore, in order to quantitatively evaluate the binding of /sup 125/I-..beta..-EP in sera from rats and humans, the authors utilized four other methods (ultrafiltration, charcoal adsorption, polyethylene glycol precipitation and equilibrium gel filtration). These methods corresponded well with each other and indicated 35-44% binding of /sup 125/I-..beta..-EP in rat serum. Binding of /sup 125/I-..beta..-EP in normal human serum was 36%, determined by ultrafiltration. Serum protein binding of /sup 125/I-..beta..-EP was concentration independent over the concentration range studied (1-1000 nM). 23 references, 4 figures, 1 table.

Affinity crosslinking of human /sup 125/I-beta-Endorphin to cell lines possessing either mu or delta binding sites was carried out. Autoradiography of SDS-PAGE gels from these crosslinked cell lines revealed that these two sites contain major peptide subunits that differ in molecular size. This confirms our earlier finding in mammalian brain which demonstrated separate and distinct subunits for mu and delta opioid receptors.

Background Bone marrow mesenchymal stem cells (MSCs) are one of the potential tools for treatment of the spinal cord injury; however, the survival and differentiation of MSCs in an injured spinal cord still need to be improved. In the present study, we investigated whether Governor Vessel electro-acupuncture (EA) could efficiently promote bone marrow mesenchymal stem cells (MSCs) survival and differentiation, axonal regeneration and finally, functional recovery in the transected spinal cord. Results The spinal cords of adult Sprague-Dawley (SD) rats were completely transected at T10, five experimental groups were performed: 1. sham operated control (Sham-control); 2. operated control (Op-control); 3. electro-acupuncture treatment (EA); 4. MSCs transplantation (MSCs); and 5. MSCs transplantation combined with electro-acupuncture (MSCs+EA). After 2-8 weeks of MSCs transplantation plus EA treatment, we found that the neurotrophin-3 (NT-3), cAMP level, the differentiation of MSCs, the 5-HT positive and CGRP positive nerve fibers in the lesion site and nearby tissue of injured spinal cord were significantly increased in the MSCs+EA group as compared to the group of the MSCs transplantation or the EA treated alone. Furthermore, behavioral test and spinal cord evoked potentials detection demonstrated a significantly functional recovery in the MSCs +EA group. Conclusion These results suggest that EA treatment may promote grafted MSCs survival and differentiation; MSCs transplantation combined with EA treatment could promote axonal regeneration and partial locomotor functional recovery in the transected spinal cord in rats and indicate a promising avenue of treatment of spinal cord injury.

1987-07-01

In order to simulate the distribution and elimination of radioiodinated human beta-endorphin (/sup 125/I-beta-EP) after iv bolus injection in rats, we proposed a physiologically based pharmacokinetic model incorporating diffusional transport of /sup 125/I-beta-EP across the capillary membrane. This model assumes that the distribution of /sup 125/I-beta-EP is restricted only within the blood and the tissue interstitial fluid, and that a diffusional barrier across the capillary membrane exists in each tissue except the liver. The tissue-to-blood partition coefficients were estimated from the ratios of the concentration in tissues to that in arterial plasma at the terminal (pseudoequilibrium) phase. The total body plasma clearance (9.0 ml/min/kg) was appropriately assigned to the liver and kidney. The transcapillary diffusion clearances of /sup 125/I-beta-EP were also estimated and shown to correlate linearly with that of inulin in several tissues. Numerically solving the mass-balance differential equations as to plasma and each tissue simultaneously, simulated concentration curves of /sup 125/I-beta-EP corresponded well with the observed data. It was suggested by the simulation that the initial rapid disappearance of /sup 125/I-beta-EP from plasma after iv injection could be attributed in part to the transcapillary diffusion of the peptide.

Full Text Available INTRODUCTION Labor pain is very frequent in clinical practice, but the underlying mechanisms as well as numerous neuroendocrine responses activated by such pain have not been fully explained yet. OBJECTIVE The objective of the study was to determine the influence of labor pain on plasma levels of cortisol and opioid peptide ß-endorphin. METHOD Cortisol and ß-endorphin levels were measured in blood plasma of: health, non-pregnant women (group 1, n=8, health pregnant women (group 2, n=8 and in parturitions, through fourth ages (group 3, n=8, Plasma level of cortisol was measured by radioimmunoassay, and ß-endorphin by enzyme immunoassay. Data were expressed as mean ± standard error of mean and were analyzed by Student's t test and Mann Whitney test. RESULTS Plasma level of cortisol in group 2 was significantly increased compared to the group 1. During labor progression, plasma level of cortisol was rising till the third labor age. Plasma level of cortisol in fourth labor age was not significantly different from the ag.e one and group 1. Plasma level of ß-endorphin was (n.g/L: in group 1:64±20, group 2:70±22, group 3:the first labor age: 75±15, the second labor age: 193±54, the third labor age: 346+97 and the fourth labor age: 114±31. CONCLUSION These results indicate that both ß-endorphin and cortisol are involved in regulation and modulation of labor pain and stress.

The authors have measured {mu} and {delta} opioid receptor sites on intact SK-N-SH and NG108-15 neuroblastoma cells, respectively, in culture. Use of {sup 125}I-{beta}-endorphin ({beta}E) as a tracer, together with {beta}E(6-31) to block high-affinity non-opioid binding in both cell lines, permitted the measurement of cell surface {mu} and {delta} opioid receptor sites. Labeling was at {delta} sites in NG108-15 cells and predominantly at {mu} sites in SK-N-SH cells. Pretreatment with the {mu} and {delta} agonist, DADLE, caused a rapid loss of cell surface {delta} receptor sites in NG108-15 cells, but failed to reduce significantly {mu} receptor density in SK-N-SH cells.

This note describes the technical details of a cerebrospinal fluid (CSF) B-Endorphin (B-End) radioimmunoassay (RIA). We used an antiserum raised in rabbits against human B-End which cross-reacs 100% with B-Lipotrophin (B-Lph). Thus, filtration chromatography is used to separate both peptides. The assay is sensitive (limit detection=14 pmoles/l), reproducible (the intra and inter assay coefficients of variation are 5 and 6% respectively). Specificity studies are performed to verify the cross-reactions with other opioid peptides and the non specific reactions with the biological fluid (CSF). In order to evaluate the effects of iodine-containing contrast media on the RIA, additional standard curves were analyzed in the presence of varying concentrations of two contrast materials [fr

Angina pectoris (Angina) is a medical condition related to myocardial ischemia. Although acupuncture has been widely accepted as a clinical approach for angina, there is no sufficient evidence of its effectiveness against this syndrome, and its mechanisms have not yet been well elucidated. We develop this protocol to confirm the clinical efficacy of electro-acupuncture on stable angina pectoris by needling on acupoint Neiguan (PC6). Furthermore, we employ high-throughput sequencing technology to investigate the gene expression profiling and determine involvement of histone modifications in the regulation of genes after electro-acupuncture treatment. A randomized, controlled, double-blinded (assessor and patients) trial will be carried out. Sixty participants will be randomly assigned to two acupuncture treatment groups and one control group in a 1:1:1 ratio. Participants in acupuncture groups will receive 12 sessions of electro-acupuncture treatment across 4 weeks, followed by a 12-week randomization period. The acupuncture groups are divided into Neiguan (PC6) on Pericardium Meridian of Hand-jueyin or a non-acupoint. The primary clinical measure of effect is the frequency of angina attacks between these groups for four weeks after randomization. RNAs are extracted from peripheral neutrophils collected from all participants on day 0, day 30, and week 16, and are processed to RNA-Seq. We then investigate profiles of histone modifications by ChIP-Seq, for H3 Lysine 4 (H3K4me) and acetylation of H3 Lysine 27 (H3K27ac), in the presence or absence of acupuncture treatment. This study determines the efficacy and mechanisms of electro-acupuncture on stable angina pectoris. We focus on effectiveness of acupuncture on alleviating symptoms of myocardial ischemia and the gene regulation and the chromatin remodeling marks, including H3K4me1, H3K4me2, and H3K27ac, which could be key factors for regulating gene expressions caused by electro-acupuncture treatment at Neiguan.

Prospective Tests on Biological Models of Acupuncture

Full Text Available The biological effects of acupuncture include the regulation of a variety of neurohumoral factors and growth control factors. In science, models or hypotheses with confirmed predictions are considered more convincing than models solely based on retrospective explanations. Literature review showed that two biological models of acupuncture have been prospectively tested with independently confirmed predictions: The neurophysiology model on the long-term effects of acupuncture emphasizes the trophic and anti-inflammatory effects of acupuncture. Its prediction on the peripheral effect of endorphin in acupuncture has been confirmed. The growth control model encompasses the neurophysiology model and suggests that a macroscopic growth control system originates from a network of organizers in embryogenesis. The activity of the growth control system is important in the formation, maintenance and regulation of all the physiological systems. Several phenomena of acupuncture such as the distribution of auricular acupuncture points, the long-term effects of acupuncture and the effect of multimodal non-specific stimulation at acupuncture points are consistent with the growth control model. The following predictions of the growth control model have been independently confirmed by research results in both acupuncture and conventional biomedical sciences: (i Acupuncture has extensive growth control effects. (ii Singular point and separatrix exist in morphogenesis. (iii Organizers have high electric conductance, high current density and high density of gap junctions. (iv A high density of gap junctions is distributed as separatrices or boundaries at body surface after early embryogenesis. (v Many acupuncture points are located at transition points or boundaries between different body domains or muscles, coinciding with the connective tissue planes. (vi Some morphogens and organizers continue to function after embryogenesis. Current acupuncture research suggests a

Peptide E (a 25-amino acid peptide derived from proenkephalin A) and beta-endorphin (a 31-amino acid peptide derived from proopiomelanocortin) bind with high affinity to opioid receptors and share structural similarities but induce analgesic effects of very different intensity. Indeed, whereas they possess the same N-terminus Met-enkephalin message sequence linked to a helix by a flexible spacer and a C-terminal part in random coil conformation, in contrast with peptide E, beta-endorphin produces a profound analgesia. To determine the key structural elements explaining this very divergent opioid activity, we have compared the structural and pharmacological characteristics of several chimeric peptides derived from peptide E and beta-endorphin. Structures were obtained under the same experimental conditions using circular dichroism, computational estimation of helical content and/or nuclear magnetic resonance spectroscopy (NMR) and NMR-restrained molecular modeling. The hot-plate and writhing tests were used in mice to evaluate the antinociceptive effects of the peptides. Our results indicate that neither the length nor the physicochemical profile of the spacer plays a fundamental role in analgesia. On the other hand, while the functional importance of the helix cannot be excluded, the last 5 residues in the C-terminal part seem to be crucial for the expression or absence of the analgesic activity of these peptides. These data raise the question of the true function of peptides E in opioidergic systems. Copyright (c) 2010 Elsevier Inc. All rights reserved.

There is growing experimental evidence that beta-endorphin immunoreactivity is raised by surgical stress in patients undergoing general anesthesia. As the assay methods employed to date did not allow to fully discriminate between beta-endorphin and its immediate precursor, beta-lipotropin, the authors have investigated in the present study plasma levels of these two peptides by separating them by chromatography on plasma extracts prior to radioimmunoassay. Beta-lipotropin, but not beta-endorphin, plasma levels were found to be significantly elevated during surgery in the general anesthesia group, while no change was found in either peptide concentration in the spinal one. Cortisol plasma levels also increased significantly 90 minutes after the beginning of surgery. Although the sampling time they adopted may have prevented them from detecting an early peak of beta-endorphin during the first 30 minutes of surgery, the major component of the pituitary opioid response to surgical stress appears to be related to beta-lipotropin. This is in agreement with results of experimental work on various kinds of stress in animals and humans and seems to rule out a role for plasma beta-endorphin in post-operative analgesia. 38 references, 1 figure, 1 table.

Information Models of Acupuncture Analgesia and Meridian Channels

2010-12-01

Full Text Available Acupuncture and meridian channels have been major components of Chinese and Eastern Asian medicine—especially for analgesia—for over 2000 years. In recent decades, electroacupuncture (EA analgesia has been applied clinically and experimentally. However, there were controversial results between different treatment frequencies, or between the active and the placebo treatments; and the mechanisms of the treatments and the related meridian channels are still unknown. In this study, we propose a new term of infophysics therapy and develop information models of acupuncture (or EA analgesia and meridian channels, to understand the mechanisms and to explain the controversial results, based on Western theories of information, trigonometry and Fourier series, and physics, as well as published biomedical data. We are trying to build a bridge between Chinese medicine and Western medicine by investigating the Eastern acupuncture analgesia and meridian channels with Western sciences; we model the meridians as a physiological system that is mostly constructed with interstices in or between other physiological systems; we consider frequencies, amplitudes and wave numbers of electric field intensity (EFI as information data. Our modeling results demonstrate that information regulated with acupuncture (or EA is different from pain information, we provide answers to explain the controversial published results, and suggest that mechanisms of acupuncture (or EA analgesia could be mostly involved in information regulation of frequencies and amplitudes of EFI as well as neuronal transmitters such as endorphins.

β-endorphin is a brain peptide with potent morphine-like activity structurally related to the anterior pituitary hormone β-lipotrophin (β-L.P.H.). A radioimmunoassay has been developed for human β-endorphin in plasma and cerebrospinal fluid (C.S.F.). Since the antiserum also reacts with β-L.P.H., β-endorphin was distinguished by using a second antiserum which measures β-L.P.H. alone. With these two immunoassay systems and gel chromatography, β-endorphin was found in all 20 C.S.F. samples tested at a concentration always higher than, but with no other relationship to, that in plasma. β-endorphin was found in C.S.F. of patients who had hypopituitarism and undetectable plasma-β-endorphin, suggesting that it is synthesised in the brain rather than in the pituitary.

Acupuncture is one of the most effective alternative medical treatments in pain management with the advantages of simple application, low cost and minimal side effects. However its scientific evidence and laws of action are not very clear in cancer pain relieving. The aim of this study was to examine the immediate and therapeutic anti-hyperalgesic effect of electro-acupuncture (EA) on a mouse model of cutaneous cancer pain. B16-BL6 melanoma cells were inoculated into the plantar region of unilateral hind paw and the thermal hyperalgesia was measured by using radiant heat test and hot plate test. C57BL/6 mice showed moderate and marked hyperalgesia during days 8-12 and from day 14 after the orthotopic inoculation of B16-BL6 melanoma cells into the hind paw. Single EA on day 8 after inoculation showed significant analgesic effect immediately after the treatment, the analgesic effect reached its maximum within 15-30min and declined to its minimum at 50min after EA treatment. Single EA treatment on day 20 showed no significant analgesic effect; Repeated EA treatments (started from day 8, once every other day) showed therapeutic analgesic effect, while it showed no therapeutic effect when started from day 16, a relatively late stage of this cancer pain model. The results demonstrated that EA had anti-hyperalgesic effect on early stage of cutaneous cancer pain but not on late stage. These results indicated a tight correlation of EA anti-hyperalgesic effects with the time window of cancer pain.

According to the Traditional Chinese Medicine theory of acupuncture, Baihui (GV20) is applied to treat neurological and psychiatric disorders. However, the relationships between neural responses and GV20 remain unknown. Thus, the main aim of this study was to examine the brain responses induced by electro-acupuncture stimulation (EAS) at GV20. Functional magnetic resonance imaging (fMRI) was performed in 33 healthy subjects. Based on the non-repeated event-related (NRER) paradigm, group differences were examined between GV20 and a sham acupoint using the regional homogeneity (ReHo) method. Compared with the sham acupoint, EAS at GV20 induced increased ReHo in regions including the orbital frontal cortex (OFC), middle cingulate cortex (MCC), precentral cortex, and precuneus (preCUN). Decreased ReHo was found in the anterior cingulate cortex (ACC), supplementary motor area (SMA), thalamus, putamen, and cerebellum. The current findings provide preliminary neuroimaging evidence to indicate that EAS at GV20 could induce a specific pattern of neural responses by analysis of ReHo of brain activity. These findings might improve the understanding of mechanisms of acupuncture stimulation at GV20.

. Review criteria called for inclusion of all published and unpublished randomised controlled trials comparing acupuncture versus control acupuncture, no treatment, medication, other structured psychotherapies (cognitive-behavioural therapy, psychotherapy, or counselling), or standard care. Modes of treatment included acupuncture, electro-acupuncture, and laser acupuncture. Participants included adult men and women with depression diagnosed by Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV), Research Diagnostic Criteria (RDC), International Statistical Classification of Diseases and Related Health Problems (ICD), or Chinese Classification of Mental Disorders Third Edition Revised (CCMD-3-R). If necessary, we used trial authors' definitions of depressive disorder. We performed meta-analyses using risk ratios (RRs) for dichotomous outcomes and standardised mean differences (SMDs) for continuous outcomes, with 95% confidence intervals (CIs). Primary outcomes were reduction in the severity of depression, measured by self-rating scales or by clinician-rated scales, and improvement in depression, defined as remission versus no remission. We assessed evidence quality using the GRADE method. This review is an update of previous versions and includes 64 studies (7104 participants). Most studies were at high risk of performance bias, at high or unclear risk of detection bias, and at low or unclear risk of selection bias, attrition bias, reporting bias, and other bias.Acupuncture versus no treatment/wait list/treatment as usualWe found low-quality evidence suggesting that acupuncture (manual and electro-) may moderately reduce the severity of depression by end of treatment (SMD -0.66, 95% CI -1.06 to -0.25, five trials, 488 participants). It is unclear whether data show differences between groups in the risk of adverse events (RR 0.89, 95% CI 0.35 to 2.24, one trial, 302 participants; low-quality evidence).Acupuncture versus control acupuncture (invasive

The role played by central 5-hydroxytryptamine (5-HT) in electroacupuncture analgesia has been studied in rats by means of autoradiography with isotopic tracers 3 H-5-HT. The purpose of the study is to determine the localization of 3 H-5-HT in the midbrain raphe nuclei and in the mesencephalon aquaeduct as well as periaquaeductal gray matter. Parallel experiments were studied by freezing microautoradiographic method and histo-fixative microautoradiographic method. The analgesic effect of acupuncture can be enhanced or lowered by the increment or the decrement of the 5-HT level in the midbrain raphe nuclei and in the mesencephalon aquaeduct as well as periaquaeductal gray matter. The results show that when the rats were subjected to electro-acupuncture analgesia, the microautoradiographic intensities of 3 H-5-HT both in the midbrain raphe nuclei and in the areas of mesencephalon aqueduct were significantly increased. It may be observed that the release of 5-HT in these regions of the brain is accelerated during acupuncture analgesia. From this it can be concluded that the midbrain raphe nuclei and the mesencephalon aquaeduct as well as the periaquaeductal gray matter are closely related to acupuncture analgesia. The results imply that 5-HT in these areas may be one of the most important neurochemical agents mediating acupuncture analgesia

Full Text Available Background. Allergic rhinitis (AR significantly impairs the quality of life of the patients; however, a questionnaire alone is an insufficient and subjective measure of this condition. Obtaining an objective clinical assessment of the level of impairment will be valuable for its treatment. β-Endorphin is one of the most important mediators of both mental state and specific immunity. Thus, we investigated the possibility of using β-endorphin as a biomarker for evaluating the impairment level in AR. Methods. This study included 48 patients with AR and 32 healthy volunteers. The serum β-endorphin level was determined by enzyme immunoassay, and the serum-specific IgE and total IgE levels were determined by immunoblot assay. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ was used to assess the impairment level in the symptom duration. Results. The β-endorphin concentration was significantly decreased in AR patients compared to the healthy controls (p=0.000, p0.05. Conclusion. β-Endorphin is a systemic biomarker that has the potential to assess the impairment level in AR and may therefore be a novel therapeutic target for the treatment of AR.

Plasma clearance kinetics for Beta Endorphin (BEP) are not well-defined and no definitive data exist for lean versus obese animals. To determine such kinetic parameters, a bolus of 125 I BEP (1μCi/kg) was infused into awake lean(L) and obese(O) Zucker rats. Arterial blood samples were withdrawn initially at 20 seconds intervals and less frequently as a 3-hour experimental period progressed. Donor rat blood was infused (venous catheter) to replace withdrawn blood. At 180 minutes approximately 10% of the initial dose remained in the plasma. Clearance kinetics for 125 I BEP were analyzed by compartmental analysis. A 3-component equation (i.e., 3 compartment model) provided the best fit for both L and O groups. Plasma transit times were very rapid; however, plasma fractional catabolic rate was low. Plasma mean residence time was similar for both groups (50 minutes) as was recycle time. These data suggest that BEP kinetics are similar in L and O rats, and that this peptide may undergo extensive recycling into and out of the plasma compartment. The identity of the other two compartments requires further investigation

Objectives We examined the effect of changing treatment timing and the use of manual, electro acupuncture on the symptoms of primary dysmenorrhea. Methods A randomised controlled trial was performed with four arms, low frequency manual acupuncture (LF-MA), high frequency manual acupuncture (HF-MA), low frequency electro acupuncture (LF-EA) and high frequency electro acupuncture (HF-EA). A manualised trial protocol was used to allow differentiation and individualized treatment over three months. A total of 74 women were randomly assigned to one of the four groups (LF-MA n = 19, HF-MA n = 18, LF-EA n = 18, HF-EA n = 19). Twelve treatments were performed over three menstrual cycles, either once per week (LF groups) or three times in the week prior to menses (HF groups). All groups received a treatment in the first 48 hours of menses. The primary outcome was the reduction in peak menstrual pain at 12 months from trial entry. Results During the treatment period and nine month follow-up all groups showed statistically significant (p 0.05). Health related quality of life increased significantly in six domains in groups having high frequency of treatment compared to two domains in low frequency groups. Manual acupuncture groups required less analgesic medication than electro-acupuncture groups (p = 0.02). HF-MA was most effective in reducing secondary menstrual symptoms compared to both–EA groups (p<0.05). Conclusion Acupuncture treatment reduced menstrual pain intensity and duration after three months of treatment and this was sustained for up to one year after trial entry. The effect of changing mode of stimulation or frequency of treatment on menstrual pain was not significant. This may be due to a lack of power. The role of acupuncture stimulation on menstrual pain needs to be investigated in appropriately powered randomised controlled trials. PMID:28700680

Alpha-blockers and antibiotics are most commonly used to treat chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in clinical practice. Currently, increasing evidence also suggests acupuncture as an effective strategy. This network meta-analysis intended to assess the comparative efficacy and safety of acupuncture, alpha-blockers and antibiotics for CP/CPPS. Twelve trials involving 1203 participants were included. Based on decreases in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score, a network meta-analysis indicated that electro-acupuncture (standard mean difference [SMD]: 4.29; 95% credible interval [CrI], 1.96–6.65), acupuncture (SMD: 3.69; 95% CrI, 0.27–7.17), alpha-blockers (SMD: 1.85; 95% CrI, 1.07–2.64), antibiotics (SMD: 2.66; 95% CrI, 1.57–3.76), and dual therapy (SMD: 3.20; 95% CrI, 1.95–4.42) are superior to placebo in decreasing this score. Additionally, electro-acupuncture (SMD: 2.44; 95% CrI, 0.08–4.83) and dual therapy (SMD: 1.35; 95% CrI, 0.07–2.62) were more effective than alpha-blockers in decreasing the total NIH-CPSI total score. Other network meta-analyses did not show significant differences between interventions other placebo. The incidence of adverse events of acupuncture was relatively rare (5.4%) compared with placebo (17.1%), alpha-blockers (24.9%), antibiotics (31%) and dual therapy (48.6%). Overall, rank tests and safety analyses indicate that electro-acupuncture/acupuncture may be recommended for the treatment of CP/CPPS. PMID:27759111

Objective: The specific brain effects of acupoint are important scientific concern in acupuncture. However, previous acupuncture fMRI studies focused on acupoints in muscle layer on the limb. Therefore, researches on acupoints within connective tissue at trunk are warranted. Material and Methods: Brain effects of acupuncture on abdomen at acupoints Guanyuan (CV4) and Zhongwan (CV12) were tested using fMRI on 21 healthy volunteers. The data acquisition was performed at resting state, during needle retention, electroacupuncture (EA) and post-EA resting state. Needling sensations were rated after every electroacupuncture (EA) procedure. The needling sensations and the brain functional activity and connectivity were compared between CV4 and CV12 using SPSS, SPM2 and the local and remote connectivity maps. Results and conclusion: EA at CV4 and CV12 induced apparent deactivation effects in the limbic-paralimbic-neocortical network. The default mode of the brain was modified by needle retention and EA, respectively. The functional brain network was significantly changed post EA. However, the minor differences existed between these two acupoints. The results demonstrated similarity between functional brain network mode of acupuncture modulation and functional circuits of emotional and cognitive regulation. Acupuncture may produce analgesia, anti-anxiety and anti-depression via the limbic-paralimbic-neocortical network (LPNN).

In the current study, we aimed to investigate whether NADPH oxidase, a major ROS-producing enzyme, was involved in the antioxidant effect of acupuncture on cognitive impairment after cerebral ischaemia. The cognitive function, infract size, neuron cell loss, level of superoxide anion and expression of NADPH oxidase subunit in hippocampus of two-vessel occlusion (2VO) rats were determined after 2-week acupuncture. Furthermore, the cognitive function and production of O2(-) were determined in the presence and absence of NADPH oxidase agonist (TBCA) and antagonist (Apocynin). The effect of acupuncture on cognitive function after cerebral ischaemia in gp91phox-KO mice was evaluated by Morris water maze. Acupuncture reduced infarct size, attenuated overproduction of O2(-), and reversed consequential cognitive impairment and neuron cell loss in 2VO rats. The elevations of gp91phox and p47phox after 2VO were significantly decreased after acupuncture treatment. However, no differences of gp91phox mRNA were found among any experimental groups. Furthermore, these beneficial effects were reversed by TBCA, whereas apocynin mimicked the effect of acupuncture by improving cognitive function and decreasing O2(-) generation. Acupuncture failed to improve the memory impairment in gp91phox KO mice. Full function of the NADPH oxidase enzyme plays an important role in neuroprotective effects against cognitive impairment via inhibition of NAPDH oxidase-mediated oxidative stress.

Beta-endorphin 1-31 biotransformation and cAMP modulation in inflammation.

Directory of Open Access Journals (Sweden)

Naghmeh Hajarol Asvadi

Full Text Available A large body of evidence now exists for the immune cell expression, production, and the release of beta-endorphin (BE 1-31 within inflamed tissue. The inflammatory milieu is characterised by increased acidity, temperature and metabolic activity. Within these harsh conditions BE 1-31 is even more susceptible to increased enzymatic degradation over that of plasma or other non-injured tissue. To elucidate the biotransformation pathways of BE 1-31 and provide an insight to the impact of inflamed tissue environments, BE 1-31 and three of its major N-terminal fragments (BE 1-11, BE 1-13 and BE 1-17 were incubated in inflamed tissue homogenates at pH 5.5 for 2 hrs. In addition, the potency of BE 1-31 and five main N--terminal fragments (BE 1-9, BE 1-11, BE 1-13, BE 1-17, BE 1-20 was assessed at mu-opioid receptors (MOR, delta-opioid receptors (DOR, and kappa-opioid receptors (KOR. Opioid receptor potency was investigated by examining the modulation of forskolin induced cAMP accumulation. The majority of the N-terminal fragment of BE 1-31 had similar efficacy to BE 1-31 at MOR. The shortest of the major N-terminal fragments (BE 1-9, had partial agonist activity at MOR but possessed the highest potency of all tested peptides at DOR. There was limited effect for BE 1-31 and the biotransformed peptides at KOR. Major N-terminal fragments produced within inflamed tissue have increased presence within inflamed tissue over that of the parent molecule BE 1-31 and may therefore contribute to BE 1-31 efficacy within disease states that involve inflammation.

Acupuncture as Treatment of Hot Flashes and the Possible Role of Calcitonin Gene-Related Peptide

Directory of Open Access Journals (Sweden)

Full Text Available The mechanisms behind hot flashes in menopausal women are not fully understood. The flashes in women are probably preceded by and actually initiated by a sudden downward shift in the set point for the core body temperature in the thermoregulatory center that is affected by sex steroids, β-endorphins, and other central neurotransmitters. Treatments that influence these factors may be expected to reduce hot flashes. Since therapy with sex steroids for hot flashes has appeared to cause a number of side effects and risks and women with hot flashes and breast cancer as well as men with prostate cancer and hot flashes are prevented from sex steroid therapy there is a great need for alternative therapies. Acupuncture affecting the opioid system has been suggested as an alternative treatment option for hot flashes in menopausal women and castrated men. The heat loss during hot flashes may be mediated by the potent vasodilator and sweat gland activator calcitonin gene-related peptide (CGRP the concentration of which increases in plasma during flashes in menopausal women and, according to one study, in castrated men with flushes. There is also evidence for connections between the opioid system and the release of CGRP. In this paper we discuss acupuncture as a treatment alternative for hot flashes and the role of CGRP in this context.

The role of electro-acupuncture (EA) stimulation on motor symptoms in Parkinson's disease (PD) has not been well studied. In a rat hemiparkinsonian model induced by unilateral transection of the medial forebrain bundle (MFB), EA stimulation improved motor impairment in a frequency-dependent manner. Whereas EA stimulation at a low frequency (2 Hz) had no effect, EA stimulation at a high frequency (100 Hz) significantly improved motor coordination. However, neither low nor high EA stimulation could significantly enhance dopamine levels in the striatum. EA stimulation at 100 Hz normalized the MFB lesion-induced increase in midbrain GABA content, but it had no effect on GABA content in the globus pallidus. These results suggest that high-frequency EA stimulation improves motor impairment in MFB-lesioned rats by increasing GABAergic inhibition in the output structure of the basal ganglia.

In order to investigate the therapeutic mechanisms of acupuncture pints in cerebrovascular ischemic patients and normal volunteers, FDG PET was adopted. Changes in cerebral glucose metabolism and cerebral functional activity before and after electro-acupuncture treatment were studied in 12 normal volunteers and 11 cerebrovascular ischemic patients. The PET imaging was read by visual interpretation and calculated by semi-quantitative analysis. After acupuncture, cerebral glucose metabolism of the normal group is higher in the frontal lobe, temporal lobe, thalamus bilaterally and cerebellum contralaterally. The cerebrovascular ischemic patients had manifested greater response in their lesions than in their normal regions of the two tested groups, as well as than in their normal regions of the whole brain, after acupuncture treatment. The study shows that the regulatory effects of acupuncture on the central nervous system influence the brain at multiple-sections, multiple-directions and multiple-levels of brain function. It conforms to the holistic and bi-directions regulatory laws of acupuncture

Cerebrospinal fluid endorphins in schizophrenia

Opioid-receptor-active material, endorphins, has been measured in cerebrospinal fluid samples obtained from schizophrenics. A chromatographic procedure isolated the Fraction I endorphin which was quantitated in a receptorassay. At least two cerebrospinal fluid samples were obtained from each patient, at day 0 with no medication and at days 30 and 60 after medication with fluphenazine under standardized conditions. Three series of patients were included: acute schizophrenics (n=11); re-entry schizophrenics (n=7) who have previously been treated with neuroleptics but were readmitted to hospital usually as a consequence of stopped medication, and chronic schizophrenics (n=9) who had been without neuroleptics for at least 2 weeks prior to day 0. At day 0, 6/9 acute cases, 4/6 of re-entry and 2/9 chronic cases had endorphin levels above the range of healthy volunteers. The levels in chronic cases were significantly lower than those in acute cases. Treatment with neuroleptics significantly lowered the endorphin levels in acute cases. These results confirm and extend previous observations. (author)

Methamphetamine is one of the widely abused drugs. In spite of a number of studies, there is still little successful therapy to suppress the methamphetamine abuse. Acupuncture has shown to attenuate the reinforcing effects of psychostimulant. Based on, the present study investigated if acupuncture could suppress intravenous methamphetamine self-administration behavior. In addition, a possible neuronal mechanism was investigated. Male Sprague-Dawley rats weighing 270-300g were trained to intake food pellet. After catheter implantation, animal was trained to self-administer methamphetamine (0.05mg/kg) intravenously using fixed ratio 1 schedule in daily 2h session during 3 weeks. After training, rats who established baseline (infusion variation less than 20% of the mean for 3 consecutive days) received acupuncture treatment on the next day. Acupuncture was performed at each acupoint manually. In the second experiment, the selective antagonists of GABA A or GABA B receptor were given before acupuncture to investigate the possible neuronal involvement of GABA receptor pathway in the acupuncture effects. C-Fos expression was examined in the nucleus accumbens to support behavioral data. Acupuncture at HT7, but not at control acupoint LI5, reduced the self-administration behavior significantly. Also, the effects of acupuncture were blocked by the GABA receptor antagonists. C-Fos expression was shown to be parallel with the behavioral data. Results of this study have shown that acupuncture at HT7 suppressed methamphetamine self-administration through GABA receptor system, suggesting that acupuncture at HT7 can be a useful therapy for the treatment of methamphetamine abuse.

β-Endorphin (BEP)-producing neuron in the hypothalamus plays a key role in bringing the stress axis to a state of homeostasis and maintaining body immune defense system. Long-term delivery of BEP to obtain beneficial effect on chemoprevention is challenging, as the peptides rapidly develop tolerance. Using rats as animal models, we show here that transplantation of BEP neurons into the hypothalamus suppressed carcinogens- and hormone-induced cancers in various tissues and prevented growth and metastasis of established tumors via activation of innate immune functions. In addition, we show that intracerebroventricular administration of nanosphere-attached dibutyryl cyclic adenosine monophosphate (dbcAMP) increased the number of BEP neurons in the hypothalamus, reduced the stress response, enhanced the innate immune function, and prevented tumor cell growth, progression, and metastasis. BEP neuronal supplementation did not produce any deleterious effects on general health but was beneficial in suppressing age-induced alterations in physical activity, metabolic, and immune functions. We conclude that the neuroimmune system has significant control over cancer growth and progression, and that activation of the neuroimmune system via BEP neuronal supplementation/induction may have therapeutic value for cancer prevention and improvement of general health. ©2014 American Association for Cancer Research.

A wirelessly powered electro-acupuncture (EA) system with adaptive-pulsewidth (APW) monophase stimulation is presented for convenient invasive medicine. The proposed system removes cumbersome wires connected between EA nodes and an EA controller in order to realize both patients' convenience and remedial values simultaneously. An ultra-low-power stimulator integrated circuit (IC) that is integrated on the flexible-printed-circuit board (F-PCB) is attached to the tip of a needle electrode. Combined with a conductive yarn helical antenna wound around the needle electrode, the EA node receives wireless power from the EA controller using 433 MHz with the maximum loss of 6 dB. A zero-Vth nMOS rectifier harvests a supply voltage of 1.0 V from a -16-dBm incoming power signal with 32% efficiency. To deal with a body impedance variation (BIV) in the range of 100-200 kΩ , the proposed APW stimulator IC, fabricated in a 0.18-μm 1P6M complementary metal-oxide semiconductor CMOS process and occupying 1.56 mm(2), enables constant charge injection of 80-nC/stimulation. To ensure the patients' safety, the EA node (a pair of EAs) shares ground and clock wires to operate in alternate monophase (AMP) fashion for neutralizing the injected charge. The proposed wirelessly powered EA node was verified by applying it to a chunk of pork as a body model with the wireless power supplied from an RF signal generator (output power of 10 dBm and located 30 cm away).

Acupuncture is widely applied for treatment of various neurological disorders. This manuscript will review the preclinical evidence of acupuncture in mediating neural plasticity, the mechanisms involved. We searched acupuncture, plasticity, and other potential related words at the following sites: PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), and VIP information data base. The following keywords were used: acupuncture, electroacupuncture, plasticity, neural plasticity, neuroplasticity, neurogenesis, neuroblast, stem cell, progenitor cell, BrdU, synapse, synapse structure, synaptogenesis, axon, axon regeneration, synaptic plasticity, LTP, LTD, neurotrophin, neurotrophic factor, BDNF, GDNF, VEGF, bFGF, EGF, NT-3, NT-4, NT-5, p75NTR, neurotransmitter, acetylcholine, norepinephrine, noradrenaline, dopamine, monamine. We assessed the effects of acupuncture on plasticity under pathological conditions in this review. Relevant references were reviewed and presented to reflect the effects of acupuncture on neural plasticity. The acquired literatures mainly focused on neurogenesis, alterations of synapses, neurotrophins (NTs), and neurotranimitters. Acupuncture methods mentioned in this article include manual acupuncture and electroacupuncture. The cumulative evidences demonstrated that acupuncture could induce neural plasticity in rodents exposed to cerebral ischemia. Neural plasticity mediated by acupuncture in other neural disorders, such as Alzheimer's disease, Parkinson's disease, and depression, were also investigated and there is evidence of positive role of acupuncture induced plasticity in these disorders as well. Mediation of neural plasticity by acupuncture is likely associated with its modulation on NTs and neurotransmitters. The exact mechanisms underlying acupuncture's effects on neural plasticity remain to be elucidated. Neural plasticity may be the potential bridge between acupuncture and the treatment of various

Full Text Available ß-endorphin and leucine enkephalin are neuropeptides with potent opioid activity. In a study to investigate the circadian secretion patterns of the above-mentioned, blood samples were collected hourly from 12 healthy males who were subjected to the experiment for 24 hours. Radioimmunoassays were used in the analysis of plasma samples for ß-endorphin and leucine enkephalin. Peak concentrations of ß-endorphin were demonstrated from 08:00-09:00, while peak concentrations of leucine enkephalin occured from 23:00-07:00. Trough concentrations of ß-endorphin occurred from 24:00-05:00, while trough con­centrations of leucine enkephalin were demonstrated from 09:00-12:00. The illustrated circadian secretion pattern for ß-endorphin simulates the well-known circadian rhythm of cortisol. The answer to this may be in the fact that ß-endorphin and corticotropin stem from the same precursor. The illustrated circadian secretion pattern for leucine enkephalin simulates that of melatonin. The reason for this is unclear.

Full Text Available Magnetoencephalography (MEG enables non-invasive recording of neuronal activity, with reconstruction methods providing estimates of underlying brain source locations and oscillatory dynamics from externally recorded neuromagnetic fields. The aim of our study was to use MEG to determine the effect of manual acupuncture on neuronal oscillatory dynamics. A major problem in MEG investigations of manual acupuncture is the absence of onset times for each needle manipulation. Given that beamforming (spatial filtering analysis is not dependent upon stimulus-driven responses being phase-locked to stimulus onset, we postulated that beamforming could reveal source locations and induced changes in neuronal activity during manual acupuncture. In a beamformer analysis, a two-minute period of manual acupuncture needle manipulation delivered to the ipsilateral right LI-4 (Hegu acupoint was contrasted with a two-minute baseline period. We considered oscillatory power changes in the theta (4-8Hz, alpha (8-13Hz, beta (13-30Hz and gamma (30-100Hz frequency bands. We found significant decreases in beta band power in the contralateral primary somatosensory cortex and superior frontal gyrus. In the ipsilateral cerebral hemisphere, we found significant power decreases in beta and gamma frequency bands in only the superior frontal gyrus. No significant power modulations were found in theta and alpha bands. Our results indicate that beamforming is a useful analytical tool to reconstruct underlying neuronal activity associated with manual acupuncture. Our main finding was of beta power decreases in primary somatosensory cortex and superior frontal gyrus, which opens up a line of future investigation regarding whether this contributes towards an underlying mechanism of acupuncture.

The antioxidative effect of electro-acupuncture in a mouse model of Parkinson's disease.

Full Text Available Accumulating evidence indicates that oxidative stress plays a critical role in Parkinson's disease (PD. Our previous work has shown that 100 Hz electro-acupuncture (EA stimulation at ZUSANLI (ST36 and SANYINJIAO (SP6 protects neurons in the substantia nigra pars compacta from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP toxicity in male C57BL/6 mice, a model of PD. In the present study we administered 100 Hz EA stimulation at the two acupoints to MPTP-lesioned mice for 12 sessions starting from the day prior to the first MPTP injection. We found that in the striatum of MPTP treated mice 100 Hz EA stimulation effectively inhibited the production of hydrogen peroxide and malonaldehyde, and increased glutathione concentration and total superoxide dismutase activity through biochemical methods. However, it decreased glutathione peroxidase activity via biochemical analysis and did not affect the level of 1-methyl-4-phenylpyridinium in the striatum revealed by high performance liquid chromatography with ultraviolet detection. These data suggest that 100 Hz EA stimulation at ST36 and SP6 has antioxidative effects in the MPTP model of PD. This data, along with our previous work, indicates that 100 Hz EA stimulation at ST36 and SP6 protects the nigrostriatal system by multiple mechanisms including antioxidation and antiapoptosis, and suggests that EA stimulation is a promising therapy for treating PD.

Full Text Available This study aimed to investigate the anti-inflammatory, anti-arthritic and immuno-regulatory effects of electro-acupuncture (EA at ST36 on Collagen-induced arthritis (CIA in mice. Male DBA/1J mice were divided into five groups: Normal, Control, NR (needle retention, EAI and EAII. All mice except those in the normal group were immunized with Collagen II for arthritis induction. Acupuncture needles were inserted into mice ST36 and electrical currents at a frequency of 2 Hz in a continuous rectangular wave form were conducted through the needles for 15 min, 3 times a week. EA treatments were administered for 5 weeks in the EAI group and for 9 weeks in the EAII group. The mice in the NR group were acupunctured in the same manner as the EA groups and the needles were retained for 15 min without electrical stimulation. CIA incidence analysis, ELISA, histological analysis and FACS analysis were performed to evaluate the effect of EA on CIA. EA at ST36 significantly reduced CIA incidence, IL-6, TNF-a, INF-γ, collagen II antibody, IgG and IgM levels in CIA mice serum and prevented knee joint destruction. EA at ST36 also reduced CD69+/CD3e+ cells and CD11a+/CD19+ cells in CIA mice lymph nodes, and CD11b+/Gr1+ cells in CIA mice knee joints. The ratios of CD3e+ cells to CD19+ cells, and CD8+ cells to CD4+ cells were maintained closer to the normal range in the EA groups as compared with the control group or the NR group. EAII was more effective than EAI throughout all the measurements. The NR was effective as well, though less effective than EA. EA at ST36 may have an anti-inflammatory, anti-arthritic and immuno-regulatory effects on CIA in mice. The effectiveness is stronger when EA starts earlier and is applied longer. Needle retention without electrical stimulation may be effective on CIA as well, however less effective than EA. Electrical stimulation and acupoint ST36 may have synergistic effects on CIA.

To investigate whether electro-acupuncture or physical exercise influence serum anti-Müllerian hormone (AMH), antral follicle count (AFC) or ovarian volume in women with polycystic ovary syndrome (PCOS). Secondary analyses of a prospective, randomized controlled clinical trial. University Hospital, Sweden. Seventy-four women with PCOS recruited from the general population. Women with PCOS were randomized to 16 weeks of electro-acupuncture (14 treatments), exercise (at least three times/week), or no intervention. Serum AMH recorded at baseline, after 16 weeks of intervention, and at follow up at 32 weeks. AFC, and ovarian volume assessed by magnetic resonance imaging at baseline and at follow up at 32 weeks. After 16 weeks of intervention, serum levels of AMH were significantly decreased in the electro-acupuncture group by 17.5% (p ovarian volume between baseline and follow up in the electro-acupuncture group, and by 11.7% (p = 0.01) in AFC in the physical exercise group. No other variables were affected. This study is the first to demonstrate that acupuncture reduces serum AMH levels and ovarian volume. Physical exercise did not influence circulating AMH or ovarian volume. Despite a within-group decrease in AFC, exercise did not lead to a between-group difference. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

Milk fever is a postpartum syndrome of cows characterized by acute hypocalcemia, which reduces the release of acetylcholine (ACH), inducing flaccid paralysis and recumbency. Our aim was to evaluate the effect of calcium (Ca2+) combined with naloxone (Nx, an opioid antagonist; Ca2+-Nx) on plasma concentrations of ACH, beta-endorphin (betaE), and Ca2+ just before treatment (T0) and at 15, 30, and 90 min after treatment (T15, T30, and T90, respectively). Thirty cows were divided into 3 groups of 10 cows each. In group A1, cows affected by milk fever were treated (i.v.) with a combination of 0.2 mL/kg of body weight (BW) of Ca2+ borogluconate (20%) and 0.01 mg/kg of BW of Nx hydrochloride dihydrate. In group A2, cows affected by milk fever were treated (i.v.) with 2 mL/kg of BW of Ca2+ borogluconate (20%). In group C, healthy cows were treated (i.v.) with a combination of 0.2 mL/kg of BW of Ca2+ borogluconate (20%) and 0.01 mg/kg of BW of Nx hydrochloride dihydrate. Cows underwent treatments within 24 h of calving. Blood samples were collected at T0 and at T15, T30, and T90 for quantitative determination of ACH, betaE, and Ca2+. The cows in groups A1 and A2 recovered within a mean of 20 +/- 10 min, although 4 cows in group A2 underwent a relapse. Blood Ca2+ concentrations in group C increased slightly at T30 and at T90 (T30: 8.8 +/- 0.6 mg/dL; T90: 8.7 +/- 0.6 mg/dL) after treatment, whereas the response in groups affected by milk fever was similar, even though Ca2+ concentrations showed a sharp increase (A1: 8.9 +/- 0.8 mg/dL; A2: 6.0 +/- 0.7 mg/dL), particularly at T15 in group A1. Concentrations of betaE showed a similar pattern in groups A1 and C, with an increase at T15 (A1: 8.2 +/- 1.0 ng/mL; C: 2.7 +/- 0.4 ng/mL) and a subsequent decrease until T90 (A1: 1.4 +/- 0.3 ng/mL; C: 1.4 +/- 0.4 ng/mL), whereas betaE remained constant throughout in group A2. Concentrations of ACH in group A1 decreased significantly between T0 and T15, T30, and T90 (T0: 7.2 +/- 1.1 nmol

US -endorphin-(1-27) is a naturally occurring antagonist to etorphine-induced analgesia

Energy Technology Data Exchange (ETDEWEB)

Nicolas, P.; Li, C.H.

1985-05-01

The potent opioid peptide US -endorphin is found in the brain and pituitary with two related fragments, US -endorphin-(1-27) and US -endorphin-(1-26). The fragments, retain substantial opioid-receptor binding activity but are virtually inactive analgesically. US -Endorphin-(1-27) inhibits US -endorphin-induced and etorphine-induced analgesia when coinjected intracerebroventricularly into mice. Antagonism by competition at the same site(s) is suggested from parallel shifts of the dose-response curves of etorphine or US -endorphin in the presence of US -endorphin-(1-27). Its potency is 4-5 times greater than that of the opiate antagonist naloxone. US -Endorphin-(1-26) does not antagonize the antinociceptive action of etorphine or US -endorphin in doses up to 500 pmol per animal.

Plasma beta-LPH, beta-EP and gamma-LPH concentrations were measured by radioimmunoassay in 10 pregnant women from 12 weeks gestation until term and in nine women in the early follicular phase of the cycle. There was a progressive and significant rise in the concentration of all three peptides throughout pregnancy and by 32 weeks the concentrations of beta-LPH and beta-EP were greater than the corresponding concentrations in the follicular phase: gamma-LPH was greater than in the follicular phase by the end of pregnancy in those women who were delivered after 40 weeks. The ratio of beta-LPH to gamma-LPH did not change significantly throughout pregnancy, but there was a progressive fall in the beta-LPH/beta-EP ratio. The possible presence of a 'big LPH' to explain this finding is discussed.

One Medicine, One Acupuncture

Full Text Available “One Acupuncture”, like “One Medicine”, has the potential to improve research quality and clinical outcomes. However, while human acupuncture point locations have remained largely consistent over time, the veterinary versions remain imprecise and variable. Establishing anatomical criteria for veterinary acupuncture atlases in keeping with the human template will create congruence across species, benefiting both research and practice. Anatomic criteria for points based on objectively verifiable structures will facilitate translational research. Functionally comparative innervation, in particular, should be similar between species, as the nerves initiate and mediate physiologic changes that result from point stimulation. If researchers choose points that activate different nerves in one species than in another, unpredictable outcomes may occur. Variability in point placement will impede progress and hamper the ability of researchers and clinicians to make meaningful comparisons across species. This paper reveals incongruities that remain between human and veterinary acupuncture points, illustrating the need to analyze anatomical characteristics of each point to assure accuracy in selecting transpositional acupuncture locations.

Full Text Available Peptide/protein hormones could be stored as non-toxic amyloid-like structures in pituitary secretory granules. ACTH and β-endorphin are two of the important peptide hormones that get co-stored in the pituitary secretory granules. Here, we study molecular interactions between ACTH and β-endorphin and their colocalization in the form of amyloid aggregates. Although ACTH is known to be a part of ACTH-β-endorphin aggregate, ACTH alone cannot aggregate into amyloid under various plausible conditions. Using all atom molecular dynamics simulation we investigate the early molecular interaction events in the ACTH-β-endorphin system, β-endorphin-only system and ACTH-only system. We find that β-endorphin and ACTH formed an interacting unit, whereas negligible interactions were observed between ACTH molecules in ACTH-only system. Our data suggest that ACTH is not only involved in interaction with β-endorphin but also enhances the stability of mixed oligomers of the entire system.

Primary dysmenorrhoea is the most common form of period pain and affects up to three-quarters of women at some stage of their reproductive life. Primary dysmenorrhoea is pain in the absence of any organic cause and is characterised by cramping pain in the lower abdomen, starting within the first eight to 72 hours of menstruation.This review examines the currently available evidence supporting the use of acupuncture (stimulation of points on the body using needles) and acupressure (stimulation of points on the body using pressure) to treat primary dysmenorrhoea. To determine the effectiveness and safety of acupuncture and acupressure in the treatment of primary dysmenorrhoea when compared with a placebo, no treatment, or conventional medical treatment. We searched the following databases: the Cochrane Menstrual Disorders and Subfertility Group Trials Register (to September 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library), MEDLINE, EMBASE, PsycINFO, CINAHL and Chinese databases including Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), VIP database and registers of ongoing trials. We included all published and unpublished randomised controlled trials (RCTs) comparing acupuncture with sham acupuncture or placebo control, usual care, pharmacological treatment or no treatment. We included the following modes of treatment: acupuncture, electro-acupuncture, and acupressure. Participants were women of reproductive age with primary dysmenorrhoea during the majority of the menstrual cycles or for three consecutive menstrual cycles, and moderate to severe symptoms. We calculated odds ratios (ORs) for dichotomous outcomes and mean differences (MDs) or standardised mean differences (SMDs) for continuous outcomes, with 95% confidence intervals (CIs). We pooled the data where appropriate. Our primary outcomes was pain. Secondary outcomes included menstrual symptoms, quality of life, and adverse

Locomotor sensitization to ethanol: Contribution of b-Endorphin

Full Text Available Alcohol use disorders, like all drug addictions, involve a constellation of adaptive changes throughout the brain. Neural activity underlying changes in the rewarding properties of alcohol reflect changes in dopamine transmission in mesolimbic and nigrostriatal pathways and these effects are modulated by endogenous opioids such as b-Endorphin. In order to study the role of b-Endorphin in the development of locomotor sensitization to repeated EtOH exposure, we tested transgenic mice that vary in their capacity to synthesize this peptide as a result of constitutive modification of the Pomc gene. Our results indicate that mice deficient in b-Endorphin show attenuated locomotor activation following an acute injection of EtOH (2 g/kg and, in contrast to wildtype mice, fail to demonstrate locomotor sensitization after 12 days of repeated EtOH injections. These data support the idea that b-Endorphin modulates the locomotor effects of EtOH and contributes to the neuroadaptive changes associated with chronic use.

Placebo Acupuncture Devices: Considerations for Acupuncture Research

Full Text Available Determining an appropriate control for use in acupuncture research remains one of the largest methodological challenges acupuncture researchers face. In general, acupuncture controls fall under one of two categories: (1 sham acupuncture, in which the skin is punctured with real acupuncture needles either fully at nonacupoint locations or shallowly at acupoint locations or both and (2 placebo acupuncture, which utilizes nonpenetrating acupuncture devices. In this study, we will focus on non-penetrating placebo acupuncture devices (blunted-needle and nonneedle devices that are currently available in acupuncture research. We will describe each device and discuss each device’s validation and application in previous studies. In addition, we will outline the advantages and disadvantages of these devices and highlight how the differences among placebo devices can be used to isolate distinct components of acupuncture treatment and investigate their effects. We would like to emphasize that there is no single placebo device that can serve as the best control for all acupuncture studies; the choice of an acupuncture control should be determined by the specific aim of the study.

Pro-inflammatory cytokines are important mediators of islet inflammation, leading to beta cell death in type 1 diabetes. Although alterations in both endoplasmic reticulum (ER) and cytosolic free calcium levels are known to play a role in cytokine-mediated beta cell death, there are currently no treatments targeting cellular calcium homeostasis to combat type 1 diabetes. Here we show that modulation of cellular calcium homeostasis can mitigate cytokine- and ER stress-mediated beta cell death. The calcium modulating compounds, dantrolene and sitagliptin, both prevent cytokine and ER stress-induced activation of the pro-apoptotic calcium-dependent enzyme, calpain, and partly suppress beta cell death in INS1E cells and human primary islets. These agents are also able to restore cytokine-mediated suppression of functional ER calcium release. In addition, sitagliptin preserves function of the ER calcium pump, sarco-endoplasmic reticulum Ca 2+ -ATPase (SERCA), and decreases levels of the pro-apoptotic protein thioredoxin-interacting protein (TXNIP). Supporting the role of TXNIP in cytokine-mediated cell death, knock down of TXNIP in INS1-E cells prevents cytokine-mediated beta cell death. Our findings demonstrate that modulation of dynamic cellular calcium homeostasis and TXNIP suppression present viable pharmacologic targets to prevent cytokine-mediated beta cell loss in diabetes.

Recent studies have shown that novel neuro-modulating techniques can have pain-relieving effects in the treatment of chronic pain. The aim of this work is to evaluate the effects of transcranial direct current stimulation (tDCS) in relieving fibromyalgia pain and its relation with beta-endorphin changes. Forty eligible patients with primary fibromyalgia were randomized to receive real anodal tDCS or sham tDCS of the left motor cortex (M1) daily for 10 days. Each patient was evaluated using widespread pain index (WPI), symptom severity of fibromyalgia (SS), visual analogue scale (VAS), and determination of pain threshold as a primary outcome. Hamilton depression and anxiety scales (HAM-D and HAM-A) and estimation of serum beta-endorphin level pre and post-sessions were used as secondary outcome. All rating scales were conducted at the baseline, after the 5th, 10th session, 15 days and 1 month after the end of the sessions. Eighteen patients from each group completed the follow-up schedule with no significant difference between them regarding the duration of illness or the baseline scales. A significant TIME × GROUP interaction for each rating scale (WPI, SS, VAS, pain threshold, HAM-A, HAM-D) indicated that the effect of treatment differed in the two groups with higher improvement in the experimental scores of the patients in the real tDCS group (P = 0.001 for WPI, SS, VAS, pain threshold, and 0.002, 0.03 for HAM-A, HAM-D respectively). Negative correlations between changes in serum beta-endorphin level and the changes in different rating scales were found (P = 0.003, 0.003, 0.05, 0.002, 0002 for WPI, SS, VAS, HAM-A, and HAM-D respectively). Ten sessions of real tDCS over M1 can induce pain relief and mood improvement in patients with fibromyalgia, which were found to be related to changes in serum endorphin levels.

Acupuncture induces divergent alterations of functional connectivity within conventional frequency bands: evidence from MEG recordings.

Directory of Open Access Journals (Sweden)

Youbo You

Full Text Available As an ancient Chinese healing modality which has gained increasing popularity in modern society, acupuncture involves stimulation with fine needles inserted into acupoints. Both traditional literature and clinical data indicated that modulation effects largely depend on specific designated acupoints. However, scientific representations of acupoint specificity remain controversial. In the present study, considering the new findings on the sustained effects of acupuncture and its time-varied temporal characteristics, we employed an electrophysiological imaging modality namely magnetoencephalography with a temporal resolution on the order of milliseconds. Taken into account the differential band-limited signal modulations induced by acupuncture, we sought to explore whether or not stimulation at Stomach Meridian 36 (ST36 and a nearby non-meridian point (NAP would evoke divergent functional connectivity alterations within delta, theta, alpha, beta and gamma bands. Whole-head scanning was performed on 28 healthy participants during an eyes-closed no-task condition both preceding and following acupuncture. Data analysis involved calculation of band-limited power (BLP followed by pair-wise BLP correlations. Further averaging was conducted to obtain local and remote connectivity. Statistical analyses revealed the increased connection degree of the left temporal cortex within delta (0.5-4 Hz, beta (13-30 Hz and gamma (30-48 Hz bands following verum acupuncture. Moreover, we not only validated the closer linkage of the left temporal cortex with the prefrontal and frontal cortices, but further pinpointed that such patterns were more extensively distributed in the ST36 group in the delta and beta bands compared to the restriction only to the delta band for NAP. Psychophysical results for significant pain threshold elevation further confirmed the analgesic effect of acupuncture at ST36. In conclusion, our findings may provide a new perspective to lend

Full Text Available Hyperandrogenism is a core factor in the series of reproductive and endocrine metabolic disorders involved in polycystic ovary syndrome (PCOS. Abnormalities in enzymatic activity and the expression of ovarian granular cell layer P450arom and theca cell P450c17α can lead to an atypical environment of local ovarian hormones, including excessive androgen levels. Rat models prepared with letrozole exhibit similar endocrine and histological changes to those that occur in human PCOS. We used such a model to study the role of electro-acupuncture (EA in regulating ovarian P450arom and P450c17α enzymatic activity and mRNA expression in PCOS rats. Female Sprague Dawley (SD rats aged 42 days were randomly divided into 3 groups (control, PCOS, and PCOS EA consisting of 10 rats each. The PCOS and PCOS EA groups were administered a gavage of 1.0 mg/kg(-1 of letrozole solution once daily for 21 consecutive days. Beginning in the ninth week, the PCOS EA group was administered low-frequency EA treatment daily for 14 consecutive days. After the treatment, we obtained the following results. The estrous cycles were restored in 8 of the 10 rats in the PCOS EA group, and their ovarian morphologies and ultrastructures normalized. The peripheral blood measurements (with ELISA showed significantly decreased androgens (i.e., androstenedione and testosterone with significantly increased estrogens (i.e., estrone, estradiol and increased P450arom with decreased P450C17α. Immunohistochemistry and Western blotting methods showed enhanced expression of ovarian granular cell layer P450arom as well as decreased expression of theca cell layer P450C17α.

Hyperandrogenism is a core factor in the series of reproductive and endocrine metabolic disorders involved in polycystic ovary syndrome (PCOS). Abnormalities in enzymatic activity and the expression of ovarian granular cell layer P450arom and theca cell P450c17α can lead to an atypical environment of local ovarian hormones, including excessive androgen levels. Rat models prepared with letrozole exhibit similar endocrine and histological changes to those that occur in human PCOS. We used such a model to study the role of electro-acupuncture (EA) in regulating ovarian P450arom and P450c17α enzymatic activity and mRNA expression in PCOS rats. Female Sprague Dawley (SD) rats aged 42 days were randomly divided into 3 groups (control, PCOS, and PCOS EA) consisting of 10 rats each. The PCOS and PCOS EA groups were administered a gavage of 1.0 mg/kg−1 of letrozole solution once daily for 21 consecutive days. Beginning in the ninth week, the PCOS EA group was administered low-frequency EA treatment daily for 14 consecutive days. After the treatment, we obtained the following results. The estrous cycles were restored in 8 of the 10 rats in the PCOS EA group, and their ovarian morphologies and ultrastructures normalized. The peripheral blood measurements (with ELISA) showed significantly decreased androgens (i.e., androstenedione and testosterone) with significantly increased estrogens (i.e., estrone, estradiol) and increased P450arom with decreased P450C17α. Immunohistochemistry and Western blotting methods showed enhanced expression of ovarian granular cell layer P450arom as well as decreased expression of theca cell layer P450C17α. Fluorescence quantitative PCR methods showed enhanced expression of ovarian granular cell layer P450arom mRNA as well as decreased expression of theca cell layer P450C17α mRNA.

AIM: To investigate the effect and mechanism of acupuncture at heterotopic acupoints on jejunal motility, particularly in pathological conditions. METHODS: Jejunal motility was assessed using a manometric balloon placed in the jejunum approximately 18-20 cm downstream from the pylorus and filled with approximately 0.1 mL warm water in anesthetized normal rats or rats with diarrhea or constipation. The heterotopic acupoints including LI11 (Quchi), ST37 (Shangjuxu), BL25 (Dachangshu), and the homotopic acupoint ST25 (Tianshu), and were stimulated for 60 s by rotating acupuncture needles right and left at a frequency of 2 Hz. To determine the type of afferent fibers mediating the regulation of jejunal motility by manual acupuncture, the ipsilateral sciatic A or C fibers of ST37 were inactivated by local application of the A-fiber selective demyelination agent cobra venom or the C fiber blocker capsaicin. Methoctramine, a selective M2 receptor antagonist, was injected intravenously to identify a specific role for M2 receptors in mediating the effect of acupuncture on jejunal motility. RESULTS: Acupuncture at heterotopic acupoints, such as LI11 and ST37, increased jejunal motility not only in normal rats, but also in rats with constipation or diarrhea. In normal rats, manual acupuncture at LI11 or ST37 enhanced jejunal pressure from 7.34 ± 0.19 cmH2O to 7.93 ± 0.20 cmH2O, an increase of 9.05% ± 0.82% (P acupuncture at LI11 or ST37 increased intrajejunal pressure from 8.17 ± 0.31 cmH2O to 9.86 ± 0.36 cmH2O, an increase of 20.69% ± 2.10% (P 0.05), respectively. In contrast, acupuncture ST25, a homotopic acupoint, decreased not only intrajejunal pressure, but also significantly decreased frequency in normal rats and rats with constipation or diarrhea. Following demyelination of Aδ fibers, acupuncture at ST37 again augmented intrajejunal pressure to 121.48% ± 3.06% of baseline. Following capsaicin application for 24 h, acupuncture at ipsilateral ST37 increased

Increasing evidence indicates anti-allergic and anti-inflammatory effects of electro-acupuncture (EA) therapy. However, its underlying mechanism on delayed-type hypersensitivity (DTH), a classic allergic inflammatory disease, still remains unclear. In this study, we aimed to explore the immunomodulatory mechanism of EA intervention in a mouse model of ovalbumin (OVA)-induced DTH. Mice were randomly divided into four groups: Control, OVA-DTH, DTH + EA, DTH + Sham. "Zusanli" acupoint (ST36) was used for DTH + EA, whereas a non-acupoint (localized 5 mm below the "Zusanli" acupoint) was selected for DTH + Sham. Footpad thickness was checked, and the infiltration of inflammatory cells was estimated by hematoxylin and eosin staining. Levels of IgG and IgE in serum of different groups and inflammatory cytokines in the supernatants from homogenized footpads, including IFN-γ, TNF-α, IL-4, and IL-5, were determined by ELISA. Cell proliferation of spleen lymphocytes was assayed by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT). The frequency of CD4 + IFN-γ + and CD4 + IL-4 + T cells was analyzed with flow cytometry. In addition, the mRNA and protein expression of T-bet and GATA-3 were evaluated by real-time PCR and Western blotting, respectively. Our data showed EA treatment at acupoint ST36 relieved the pathological progression of DTH responses via reduction in footpad swelling, infiltration of inflammatory cells, levels of IgG and IgE as well as decreased production of IFN-γ and TNF-α in homogenized footpad tissue. Moreover, detailed studies were performed revealing that EA attenuated the percentage of CD4 + IFN-γ + T cells and prevented Th cells differentiation into Th1 cells, and this results from inhibiting secretion of IFN-γ and suppressing expression of T-bet, an IFN-γ transcription factor. The results indicated that EA treatment improved Th1-mediated allergic skin inflammation via restoring Th1/Th2 balance by curbing Th1

The evaluation the β-endorphin plasma levels in lean women with polycystic ovary syndrome as well as in women without this disorder. The associations between β-endorphins and other laboratory parameters were also investigated. 31 women lean, defined as women with normal range body mass index, 15 with polycystic ovary syndrome and 16 without this disorder were included to the study. In all the patients the level of β-endorphins was measured. Also the diagnostic laboratory profile including hormone assessment was made in all patients. There were significant differences in β-endorphin levels between the 2 groups. The β-endorphin level was higher in the polycystic ovary syndrome group compared to the healthy controls (15.5±4.37 pg/ml vs. 6.9±2.47 pg/ml, ppolycystic ovary syndrome group. Increase in β-endorphin level of 1 pg/ml was associated with an increase of cortisol at 8 am level of 1.134 µg/dl and decrease of sex hormone binding globuline of 0.948 nmol/l in polycystic ovary syndrome group. Our study showed that the levels of β-endorphins were significantly higher in lean patients with polycystic ovary syndrome than in lean controls. Moreover, β-endorphins levels were found to be correlated with other hormonal parameters. In this respect, β-endorphins may play a role in polycystic ovary syndrome pathophysiology. © Georg Thieme Verlag KG Stuttgart · New York.

Highlights: • We analyze spike trains induced by EA before and after inhibiting SP in PC6 area. • Inhibiting SP leads to an increase of spiking rate of median nerve. • SP may modulate membrane potential to affect the spiking rate. • SP has an influence on long-range correlation of spike train evoked by EA. • SP play an important role in EA-induced neural spiking and encoding. - Abstract: Substance P (SP) participates in the neural signal transmission evoked by electro-acupuncture (EA). This paper investigates the impact of SP on the correlation of spike train in the median nerve evoked by EA at 'Neiguan' acupoint (PC6). It shows that the spiking rate and interspike interval (ISI) distribution change obviously after inhibiting SP. This variation of spiking activity indicates that SP affects the temporal structure of spike train through modulating the action potential on median nerve filaments. Furtherly, the correlation coefficient and scaling exponent are considered to measure the correlation of spike train. Scaled Windowed Variance (SWV) method is applied to calculate scaling exponent which quantifies the long-range correlation of the neural electrical signals. It is found that the correlation coefficients of ISI increase after inhibiting SP released. In addition, the scaling exponents of neuronal spike train have significant differences between before and after inhibiting SP. These findings demonstrate that SP has an influence on the long-range correlation of spike train. Our results indicate that SP may play an important role in EA-induced neural spiking and encoding.

Morphine and endorphin administered intracerebroventricularly (i.c.v.) produce analgesia by activating different descending pain inhibitory systems. Gamma irradiation attenuates the acute analgesic action of i.c.v. injected morphine in mice. This study was done to investigate the effect of-irradiation on the analgesia produced by i.c.v. injected morphine and endorphin in male ICR mice. In one group, mice were exposed to whole-body irradiation at a dose of 5 Gy from a 60 Co source and the analgesic effects were tested 5, 30, 60, 90 and 180 min after irradiation using the acetic acid-induced writhing test. The analgesic effect was produced time-dependently and reached its maximum at 90 min after irradiation. Thus, time was fixed in the following studies. In another group, mice were irradiated with 5 Gy and tested 90 minutes later for analgesia produced by i.c.v. administration of morphine or endorphin. Irradiation significantly potentiated the analgesia produced by endorphin. However, the antinociception produced by morphine was not affected by irradiation. These results support the hypothesis that morphine and endorphin administered supraspinally produce antinocieception by different neuronal mechanisms

Acupuncture is a form of Eastern medicine that has been practiced for centuries. Despite its long history and worldwide application, the biological mechanisms of acupuncture in relieving pain have been poorly defined. Recent studies in mice, however, demonstrate that acupuncture triggers increases in interstitial adenosine, which reduces the severity of chronic pain through adenosine A1 receptors, suggesting that adenosine-mediated antinociception contributes to the clinical benefits of acupu...

To investigate whether and how manual acupuncture (MA) modulates brain activities, we design an experiment where acupuncture at acupoint ST36 of the right leg is used to obtain electroencephalograph (EEG) signals in healthy subjects. We adopt the autoregressive (AR) Burg method to estimate the power spectrum of EEG signals and analyze the relative powers in delta (0 Hz–4 Hz), theta (4 Hz–8 Hz), alpha (8 Hz–13 Hz), and beta (13 Hz–30 Hz) bands. Our results show that MA at ST36 can significantly increase the EEG slow wave relative power (delta band) and reduce the fast wave relative powers (alpha and beta bands), while there are no statistical differences in theta band relative power between different acupuncture states. In order to quantify the ratio of slow to fast wave EEG activity, we compute the power ratio index. It is found that the MA can significantly increase the power ratio index, especially in frontal and central lobes. All the results highlight the modulation of brain activities with MA and may provide potential help for the clinical use of acupuncture. The proposed quantitative method of acupuncture signals may be further used to make MA more standardized. (interdisciplinary physics and related areas of science and technology)

Many important fields of research had a humble origin. In the distant past, A J P Martin's discovery that amino acids could be separated by paper chromatography and Moore and Stein's use of columns for quantitative amino acid analysis provided the first steps towards the determination of structure in complex biologically active molecules. They opened the door to reveal the essential relationship that exists between structure and function. In molecular endocrinology, for example, striking advances have been made by chemists with their expertise in the identification of structure working with biologists who contributed valuable knowledge and experience. Advantage was gained from the convergence of different background, and it is notable that the whole is greater than the sum. In the determination of structure, it may be recalled that four of the world's great pioneers (Archibald Martin, Rodney Porter, Fred Sanger and Vincent du Vigneaud) were acknowledged for their fundamental contributions when individually they were awarded the Nobel Prize. They foresaw that the identification of structure would prove of outstanding importance in the future. Indeed, study of the structures of β-endorphin and enkephalin and the different forms of opiate activity they engender has led to a transformation in our understanding of chemical transmission in the brain. © 2016 Society for Endocrinology.

Endorphinic neurons are contacting the tuberoinfundibular dopaminergic neurons in the rat brain

The anatomical relationships between endorphinic neurons and dopaminergic neurons were evaluated in the rat hypothalamus using a combination of immunocytochemistry and autoradiography. In the arcuate nucleus, endorphinic endings were seen making contacts with dopaminergic cell bodies and dendrites. No synapsis could be observed at the sites of contacts. These results strongly suggest that the endorphinic neurons are directly acting on dopaminergic neurons to modify the release of dopamine into the pituitary portal system

Recent studies support the view that cortical sensory, limbic and executive networks and the autonomic nervous system might interact in distinct manners under the influence of acupuncture to modulate pain. We performed a double-blind crossover design study to investigate subjective ratings, EEG and ECG following experimental laser pain under the influence of sham and verum acupuncture in 26 healthy volunteers. We analyzed neuronal oscillations and inter-regional coherence in the gamma band of 128-channel-EEG recordings as well as heart rate variability (HRV) on two experimental days. Pain ratings and pain-induced gamma oscillations together with vagally-mediated power in the high-frequency bandwidth (vmHF) of HRV decreased significantly stronger during verum than sham acupuncture. Gamma oscillations were localized in the prefrontal cortex (PFC), mid-cingulate cortex (MCC), primary somatosensory cortex and insula. Reductions of pain ratings and vmHF-power were significantly correlated with increase of connectivity between the insula and MCC. In contrast, connectivity between left and right PFC and between PFC and insula correlated positively with vmHF-power without a relationship to acupuncture analgesia. Overall, these findings highlight the influence of the insula in integrating activity in limbic-saliency networks with vagally mediated homeostatic control to mediate antinociception under the influence of acupuncture.

Acupuncture is often used for primary dysmenorrhea. But there is no convincing evidence due to low methodological quality. We aim to assess immediate effect of acupuncture at specific acupoint compared with unrelated acupoint and nonacupoint on primary dysmenorrhea. The Acupuncture Analgesia Effect in Primary Dysmenorrhoea-II is a multicenter controlled trial conducted in six large hospitals of China. Patients who met inclusion criteria were randomly assigned to classic acupoint (N = 167), unrelated acupoint (N = 167), or non-acupoint (N = 167) group on a 1:1:1 basis. They received three sessions with electro-acupuncture at a classic acupoint (Sanyinjiao, SP6), or an unrelated acupoint (Xuanzhong, GB39), or nonacupoint location, respectively. The primary outcome was subjective pain as measured by a 100-mm visual analog scale (VAS). Measurements were obtained at 0, 5, 10, 30, and 60 minutes following the first intervention. In addition, patients scored changes of general complaints using Cox retrospective symptom scales (RSS-Cox) and 7-point verbal rating scale (VRS) during three menstrual cycles. Secondary outcomes included VAS score for average pain, pain total time, additional in-bed time, and proportion of participants using analgesics during three menstrual cycles. Five hundred and one people underwent random assignment. The primary comparison of VAS scores following the first intervention demonstrated that classic acupoint group was more effective both than unrelated acupoint (-4.0 mm, 95% CI -7.1 to -0.9, P = 0.010) and nonacupoint (-4.0 mm, 95% CI -7.0 to -0.9, P = 0.012) groups. However, no significant differences were detected among the three acupuncture groups for RSS-Cox or VRS outcomes. The per-protocol analysis showed similar pattern. No serious adverse events were noted. Specific acupoint acupuncture produced a statistically, but not clinically, significant effect compared with unrelated acupoint and nonacupoint acupuncture in

Veening Jan G

2012-08-01

Full Text Available Abstract There is increasing evidence that non-synaptic communication by volume transmission in the flowing CSF plays an important role in neural mechanisms, especially for extending the duration of behavioral effects. In the present review, we explore the mechanisms involved in the behavioral and physiological effects of β-endorphin (β-END, especially those involving the cerebrospinal fluid (CSF, as a message transport system to reach distant brain areas. The major source of β-END are the pro-opio-melano-cortin (POMC neurons, located in the arcuate hypothalamic nucleus (ARH, bordering the 3rd ventricle. In addition, numerous varicose β-END-immunoreactive fibers are situated close to the ventricular surfaces. In the present paper we surveyed the evidence that volume transmission via the CSF can be considered as an option for messages to reach remote brain areas. Some of the points discussed in the present review are: release mechanisms of β-END, independence of peripheral versus central levels, central β-END migration over considerable distances, behavioral effects of β-END depend on location of ventricular administration, and abundance of mu and delta opioid receptors in the periventricular regions of the brain.

Electro-acupuncture (EA) is a novel therapy based on combining traditional acupuncture with modern electrotherapy, and it is currently being investigated as a treatment for ischemic stroke. In the present study, we aimed to investigate the mechanisms through which EA regulates the proliferation of neural progenitor cells (NPCs) in the cortical peri-infarct area after stroke. The neuroprotective effects of EA on ischemic rats were evaluated by determining the neurological deficit scores and cerebral infarct volumes. The proliferation of the NPCs and the activation of the Wnt/β-catenin signaling pathway in the cortical peri-infarct area were examined. Our results revealed that EA significantly alleviated neurological deficits, reduced the infarct volume and enhanced NPC proliferation [nestin/glial fibrillary acidic protein (GFAP)-double positive] in the cortex of rats subjected to middle cerebral artery occlusion (MCAO). Moreover, the Wnt1 and β-catenin mRNA and protein levels were increased, while glycogen synthase kinase-3 (GSK3) transcription was suppressed by EA. These results suggest that the upregulatory effects of EA on the Wnt/β-catenin signaling pathway may promote NPC proliferation in the cortical peri-infarct area after stroke, consequently providing a therapeutic effect against cerebral ischemia.

This research aimed to compare anti-inflammatory effects of oligonol, acupuncture, and quantum light therapy in rat models of estrogen-induced prostatitis. Adult male Wistar albino rats were grouped as follows: Group I, control (n = 10); Group II, chronic prostatitis (n = 10); Group III, oligonol (n = 10); Group IV, acupuncture (n = 10); Group V, quantum (n = 10); Group VI, oligonol plus quantum (n = 10); Group VII, acupuncture plus oligonol (n = 10); Group VIII, quantum plus acupuncture (n = 10); and Group IX, acupuncture plus quantum plus oligonol (n = 10). Chronic prostatitis (CP) was induced by the administration of 17-beta-estradiol (E2) and dihydrotestosterone (DHT). Oligonol was given for 6 weeks at a dose of 60 mg/day. Acupuncture needles were inserted at CV 3/4 and bilaterally B 32/35 points with 1-hour manual stimulation. Quantum therapy was administered in 5-minute sessions three times weekly for 6 weeks. Lateral lobes of prostates were dissected for histopathologic evaluation. Although all of the treatment modalities tested in this study showed anti-inflammatory effects in the treatment of CP in male rats, a synergistic effect was observed for oligonol plus quantum light combination. Monotherapy with oligonol showed a superior anti-inflammatory efficacy as compared to quantum light and acupuncture monotherapies.

Background One in five fibromyalgia sufferers use acupuncture treatment within two years of diagnosis. Objectives To examine the benefits and safety of acupuncture treatment for fibromyalgia. Search methods We searched CENTRAL, PubMed, EMBASE, CINAHL, National Research Register, HSR Project and Current Contents, as well as the Chinese databases VIP and Wangfang to January 2012 with no language restrictions. Selection criteria Randomised and quasi-randomised studies evaluating any type of invasive acupuncture for fibromyalgia diagnosed according to the American College of Rheumatology (ACR) criteria, and reporting any main outcome: pain, physical function, fatigue, sleep, total well-being, stiffness and adverse events. Data collection and analysis Two author pairs selected trials, extracted data and assessed risk of bias. Treatment effects were reported as standardised mean differences (SMD) and 95%confidence intervals (CI) for continuous outcomes using different measurement tools (pain, physical function, fatigue, sleep, total well-being and stiffness) and risk ratio (RR) and 95% CI for dichotomous outcomes (adverse events).We pooled data using the random-effects model. Main results Nine trials (395 participants) were included. All studies except one were at low risk of selection bias; five were at risk of selective reporting bias (favouring either treatment group); two were subject to attrition bias (favouring acupuncture); three were subject to performance bias (favouring acupuncture) and one to detection bias (favouring acupuncture). Three studies utilised electro-acupuncture (EA) with the remainder using manual acupuncture (MA) without electrical stimulation. All studies used ’formula acupuncture’ except for one, which used trigger points. Low quality evidence from one study (13 participants) showed EA improved symptoms with no adverse events at one month following treatment. Mean pain in the non-treatment control group was 70 points on a 100 point scale

As an ancient therapeutic technique in Traditional Chinese Medicine, acupuncture has been used increasingly in modern society to treat a range of clinical conditions as an alternative and complementary therapy. However, acupoint specificity, lying at the core of acupuncture, still faces many controversies. Considering previous neuroimaging studies on acupuncture have mainly employed functional magnetic resonance imaging, which only measures the secondary effect of neural activity on cerebral metabolism and hemodynamics, in the current study, we adopted an electrophysiological measurement technique named magnetoencephalography (MEG) to measure the direct neural activity. 28 healthy college students were recruited in this study. We filtered MEG data into 5 consecutive frequency bands (delta, theta, alpha, beta and gamma band) and grouped 140 sensors into 10 main brain regions (left/right frontal, central, temporal, parietal and occipital regions). Fast Fourier Transformation (FFT) based spectral analysis approach was further performed to explore the differential band-limited power change patterns of acupuncture at Stomach Meridian 36 (ST36) using a nearby nonacupoint (NAP) as control condition. Significantly increased delta power and decreased alpha as well as beta power in bilateral frontal ROIs were observed following stimulation at ST36. Compared with ST36, decreased alpha power in left and right central, right parietal as well as right temporal ROIs were detected in NAP group. Our research results may provide additional evidence for acupoint specificity.

Full Text Available The role of β-endorphin in the plasma glucose-lowering action of tetrandrine in streptozotocin-induced diabetic rats (STZ-diabetic rats was investigated. The plasma glucose concentration was assessed by the glucose oxidase method. The enzyme-linked immunosorbent assay was used to determine the plasma level of β-endorphin-like immunoreactivity (BER. The mRNA levels of glucose transporter subtype 4 (GLUT4 in soleus muscle and phosphoenolpyruvate carboxykinase (PEPCK in the liver of STZ-diabetic rats were detected by Northern blotting analysis. The expressed protein of GLUT4 or PEPCK was characterized by Western blotting analysis. Tetrandrine dose-dependently increased plasma BER in a manner parallel to the decrease of plasma glucose in STZ-diabetic rats. Moreover, the plasma glucose-lowering effect of tetrandrine was inhibited by naloxone and naloxonazine at doses sufficient to block opioid μ-receptors. Further, tetrandrine failed to produce plasma glucose-lowering action in opioid μ-receptor knockout diabetic mice. Bilateral adrenalectomy eliminated the plasma glucose-lowering effect and plasma BER-elevating effect of tetrandrine in STZ-diabetic rats. Both effects were abolished by treatment with hexamethonium or pentolinium at doses sufficient to block nicotinic receptors. Tetrandrine enhanced BER release directly from the isolated adrenal medulla of STZ-diabetic rats and this action was abolished by the blockade of nicotinic receptors. Repeated intravenous administration of tetrandrine (1.0 mg/kg to STZ-diabetic rats for 3 days resulted in an increase in the mRNA and protein levels of the GLUT4 in soleus muscle, in addition to the lowering of plasma glucose. Similar treatment with tetrandrine reversed the elevated mRNA and protein levels of PEPCK in the liver of STZ-diabetic rats. The obtained results suggest that tetrandrine may induce the activation of nicotinic receptors in adrenal medulla to enhance the secretion of β-endorphin

Full Text Available Abstract Background Recently, increasing evidence has indicated that the primary acupuncture effects are mediated by the central nervous system. However, specific brain networks underpinning these effects remain unclear. Results In the present study using fMRI, we employed a within-condition interregional covariance analysis method to investigate functional connectivity of brain networks involved in acupuncture. The fMRI experiment was performed before, during and after acupuncture manipulations on healthy volunteers at an acupuncture point, which was previously implicated in a neural pathway for pain modulation. We first identified significant fMRI signal changes during acupuncture stimulation in the left amygdala, which was subsequently selected as a functional reference for connectivity analyses. Our results have demonstrated that there is a brain network associated with the amygdala during a resting condition. This network encompasses the brain structures that are implicated in both pain sensation and pain modulation. We also found that such a pain-related network could be modulated by both verum acupuncture and sham acupuncture. Furthermore, compared with a sham acupuncture, the verum acupuncture induced a higher level of correlations among the amygdala-associated network. Conclusion Our findings indicate that acupuncture may change this amygdala-specific brain network into a functional state that underlies pain perception and pain modulation.

Lymphocytes stimulated by mitogens or antigens exhibit an enhanced calcium uptake early in the proliferation or activation response. Modulation of this calcium uptake results in alterations of proliferation and immunocompetence. β-endorphin and other opioids affect several parameters of lymphocyte competence. Limited data are available concerning the mechanism(s) of these effects. This study examines whether a possible opioid mechanism is the modification of the early calcium influx into stimulated lymphocytes. The time course of both concanavalin A (Con A) and phytohemagglutinin (PHA)-stimulated 45 Ca 2+ uptake into thymocytes was characterized to determine the optimal time for testing the effects of opioids. Β-Endorphin 1-31 significantly enhanced Con A-stimulated 45 Ca 2+ uptake into rat thymocytes. This peptide had no significant effect on PHA-simulated 45 Ca 2+ uptake or on basal thymocyte 45 Ca 2+ flux. The β/sub h/-endorphin stimulatory effect was titratable in the range of 0.1 nM to 10 μM. Naloxone did not reverse the enhancement. Met-enkephalinamide and other opioid agonists did not duplicate the stimulatory effect. Thus, the β/sub h/-endorphin 1-31 enhancement of Con A-stimulated 45 Ca 2+ uptake by rat thymocytes does not operate via classical opioid receptor mechanisms. β/sub h/-endorphin 1-31 appears to be acting on a subset of T cells that are responsive to Con A but not to PHA. 30 references, 4 figures, 1 table

The effect of chronic morphine treatment on the in vitro biosynthesis of β-endorphin by rat pars intermedia was investigated. Tolerance and physical dependence were induced in 200 g rats by the subcutaneous implantation of 75 mg morphine pellets for either 3 days or 15 days. Immediately following sacrifice of the animals the neurointermediate lobes were removed and incubated with [ 3 H]phenylalanine. The protein extracts of the lobes were analyzed for the incorporation of the labelled amino acid into total protein, pro-opiomelanocortin, β-lipotropin (β-LPH) and β-endorphin. The biosynthesized products were purified by immunoprecipitation with an antiserum to β-endorphin. The identity and purity of β-endorphin were verified by polyacrylamide disc gel electrophoresis with sodium dodecyl sulfate, and mircrosequencing. The identity of pro-opiomelanocortin (POMC) was verified by peptide mapping of its tryptic digestion products. The results showed that morphine treatment induced a decrease in the incorporation of the radioactive amino acid into total protein, pro-opiomelanocortin, β-LPH and β-endorphin. The decrease was more pronounced for the incorporation into β-LPH and β-endorphin than into pro-opiomelanocortin and total proteins, suggesting an effect of morphine treatment on the processing of the pro-opiomelanocortin to its final maturation products.

Abstract Objectives: To observe the regional cerebral metabolism changes in cerebrovascular ischemic patients and normal volunteers while acupuncture by using FDG PET. To definite the locations of the influence of these acupoints on brain function in certain regions of the cerebrum, as well as to explore the laws of therapeutic effects of acupuncture on subjects and established the One-day method for brain FDG PET scan. Methods and Materials Using FDG PET, cerebral glucose metabolism and cerebral functional changes before and after electro-acupuncture treatment were investigated in 12 normal volunteers and 8 cerebrovascular ischemic patients. These subjects were treated with acupuncture in the following points: Hegu (LI4) and Quchi (LI11) of Hand Yang-Ming meridian, Zusanli (ST36) and Shangjuxu (ST37) of Foot Yang-Ming meridian and added Motor Area and Fengchi (B20). Limbs points were contralateral to the brain points. In the normal group, the side of the body treated by acupuncture was randomly selected and in the patients groups, the sides treated were on the side of paralysis. PET imaging was read by visual interpretation and calculated in multiple ROI semi-quantitative analysis method. Therefore, the image subject method was used to demonstrate the variety of glucose metabolism after acupuncture. Results One-day method was established in these studies. PET imaging was read by visual interpretation in blind method and calculated by semi-quantitative analysis. This results shows that cerebral glucose metabolism and cerebral functional activity of the normal is higher in the frontal lobe, temporal lobe, thalamus, Sensorimotor, Parietal bilaterally and cerebellum contralaterally. After acupuncture, the increase ratio of ipslateral glucose metabolism was between 23% and 38%; while the contralateral increase ratio between 22% and 40%. Above all, the variation in cerebral glucose metabolism was predominantly contralateral cerebral regions. The cerebrovascular ischemic

This study aimed to explore the effectiveness of both acupuncture and bee venom acupuncture as adjuvant therapies for idiopathic Parkinson's disease. We recruited 43 adults with idiopathic Parkinson's disease who had been on a stable dose of antiparkinsonian medication for at least 1 month. They were randomly assigned to 1 of 3 groups: acupuncture, bee venom acupuncture, or control. All participants were assessed using the Unified Parkinson's Disease Rating Scale, the Parkinson's Disease Quality of Life Questionnaire, the Beck Depression Inventory, the Berg Balance Scale, and the time and number of steps required to walk 30 m. Treatment groups underwent stimulation of 10 acupuncture points using acupuncture or bee venom acupuncture twice a week for 8 weeks. The initial assessment was repeated at the completion of treatment. The control group did not receive any treatment. Participants in the bee venom acupuncture group showed significant improvement on the Unified Parkinson's Disease Rating Scale (total score, as well as parts II and III individually), the Berg Balance Scale, and the 30 m walking time. When compared to the control group, the bee venom acupuncture group experienced significantly greater improvement on the Unified Parkinson's Disease Rating Scale. In the acupuncture group, the Unified Parkinson's Disease Rating Scale (part III and total scores) and the Beck Depression Inventory showed significant improvement. The control group showed no significant changes in any outcome after 8 weeks. In this pilot study, both acupuncture and bee venom acupuncture showed promising results as adjuvant therapies for Parkinson's disease. Copyright © 2012 Elsevier Ltd. All rights reserved.

Acupuncture treatment is amazing but controversial. Up to now, the mechanism of treating diseases by acupuncture and moxibustion is still unclear, especially the occurrence of the molecular events in local acupoints. Herein, we report an extremely stable microsensor by modifying carbon nanotube (CNT) to the tip surface of acupuncture needle and applying this CNT-modified acupuncture needle for real time monitoring of serotonin (5-HT) in vivo. To stabilize CNT modification on the needle tip surface, poly(3,4-ethylenedioxythiophene)(PEDOT) was employed as glue water to stick CNT on the needle. The detection limit of the CNT-modified needle was found to be approximately 50 nM and 78 nM in the PBS and the cell medium, respectively. In addition, the needle showed good selectivity to some inflammatory mediators and some electroactive molecules. For the first time, the CNT-modified needle could be directly probed into rat body for real time monitoring of 5-HT in vivo, showing a great potential for better understanding the mechanism of acupuncture treatment.

Identification of endogenous opioid receptor components in rat brain using a monoclonal antibody

1988-11-01

A monoclonal antibody generated against the tertiary structure of a partially purified opioid binding protein was used to probe the structure of the dynorphin and beta-endorphin receptors. The Fab fragment 3B4F11 inhibited completely the binding of 125I-beta-endorphin and (3H)dynorphin to rat brain P2 membranes with IC50 values of 26 ng/ml and 40 ng/ml, respectively. To explore further the interaction of 3B4F11 with the beta-endorphin receptor, the effect of the Fab fragment on 125I-beta-endorphin cross-linking to rat brain membranes was examined. 125I-beta-endorphin was covalently bound to three major species of approximate molecular weights 108,000, 73,000, and 49,000. The delta-selective ligand D-Pen2, D-pen5enkephalin was least effective at inhibiting the cross-linking of beta-endorphin, whereas the micro-selective ligand Tyr-D-Ala-Gly-NMe-Phe-Gly-ol and kappa-selective ligand U50488 inhibited beta-endorphin cross-linking to the 108,000 and 73,000 Da species. Both 3B4F11 and beta-endorphin prevented the covalent binding of 125I-beta-endorphin to all three labeled species. These findings suggest that micro and kappa receptor types might have some structural similarities, whereas the delta receptor type might differ in molecular size. In addition, the micro, kappa, and delta ligands might have different primary sequences, whereas their tertiary structures might share regions of molecular homology with all three receptor constituents labeled by 125I-beta-endorphin. 3B4F11 will be a valuable tool for the purification and isolation of the several components of the beta-endorphin receptor complex.

The Anti-Inflammatory Effects of Acupuncture and Their Relevance to Allergic Rhinitis: A Narrative Review and Proposed Model

Directory of Open Access Journals (Sweden)

John L. McDonald

2013-01-01

Full Text Available Classical literature indicates that acupuncture has been used for millennia to treat numerous inflammatory conditions, including allergic rhinitis. Recent research has examined some of the mechanisms underpinning acupuncture's anti-inflammatory effects which include mediation by sympathetic and parasympathetic pathways. The hypothalamus-pituitary-adrenal (HPA axis has been reported to mediate the antioedema effects of acupuncture, but not antihyperalgesic actions during inflammation. Other reported anti-inflammatory effects of acupuncture include an antihistamine action and downregulation of proinflammatory cytokines (such as TNF-α, IL-1β, IL-6, and IL-10, proinflammatory neuropeptides (such as SP, CGRP, and VIP, and neurotrophins (such as NGF and BDNF which can enhance and prolong inflammatory response. Acupuncture has been reported to suppress the expression of COX-1, COX-2, and iNOS during experimentally induced inflammation. Downregulation of the expression and sensitivity of the transient receptor potential vallinoid 1 (TRPV1 after acupuncture has been reported. In summary, acupuncture may exert anti-inflammatory effects through a complex neuro-endocrino-immunological network of actions. Many of these generic anti-inflammatory effects of acupuncture are of direct relevance to allergic rhinitis; however, more research is needed to elucidate specifically how immune mechanisms might be modulated by acupuncture in allergic rhinitis, and to this end a proposed model is offered to guide further research.

In this postmodern society, people tend to abandon conventional medicine for alternative medical systems, such as acupuncture. What are the reasons for this defiance regarding modern rationality and individualist success? Who turns to acupuncture? This study (n=89) examined whether world views opposed to the predominance of rationality (i.e., mistrust of science, spirituality, paranormal beliefs) and individualist success or consumerism (i.e., power, achievement, and materialism), typically associated with the postmodern era, might explain this attraction toward acupuncture. Participants were recruited through Internet forums interested in complementary and alternative medicine and completed the questionnaire voluntarily. Attraction to acupuncture related negatively with materialism and achievement as well as positively with spirituality, paranormal beliefs, and mistrust in science. Spirituality, paranormal beliefs, and low achievement were the main predictors of attraction to acupuncture and explained 44% of the variance. The mistrust in science mediated the relationship between spiritual and paranormal beliefs and the attraction toward acupuncture. Low achievement explained the link between low materialism and positive attitudes toward acupuncture. The general mistrust of our rational and individualist modern society is indeed an important predictor of attraction toward acupuncture, in addition to demographic variables.

Electro-weak theory

By electro-weak theory is meant the unified field theory that describes both weak and electro-magnetic interactions. The development of a unified electro-weak theory is certainly the most dramatic achievement in theoretical physics to occur in the second half of this century. It puts weak interactions on the same sound theoretical footing as quantum elecrodynamics. Many theorists have contributed to this development, which culminated in the works of Glashow, Weinberg and Salam, who were jointly awarded the 1979 Nobel Prize in physics. Some of the important ideas that contributed to this development are the theory of beta decay formulated by Fermi, Parity violation suggested by Lee and Yang, and incorporated into immensely successful V-A theory of weak interactions by Sudarshan and Marshak. At the same time ideas of gauge invariance were applied to weak interaction by Schwinger, Bludman and Glashow. Weinberg and Salam then went one step further and wrote a theory that is renormalizable, i.e., all higher order corrections are finite, no mean feat for a quantum field theory. The theory had to await the development of the quark model of hadrons for its completion. A description of the electro-weak theory is given

Peripheral afferent mechanisms underlying acupuncture inhibition of cocaine behavioral effects in rats.

Full Text Available Administration of cocaine increases locomotor activity by enhancing dopamine transmission. To explore the peripheral mechanisms underlying acupuncture treatment for drug addiction, we developed a novel mechanical acupuncture instrument (MAI for objective mechanical stimulation. The aim of this study was to evaluate whether acupuncture inhibition of cocaine-induced locomotor activity is mediated through specific peripheral nerves, the afferents from superficial or deep tissues, or specific groups of nerve fibers. Mechanical stimulation of acupuncture point HT7 with MAI suppressed cocaine-induced locomotor activity in a stimulus time-dependent manner, which was blocked by severing the ulnar nerve or by local anesthesia. Suppression of cocaine-induced locomotor activity was elicited after HT7 stimulation at frequencies of either 50 (for Meissner corpuscles or 200 (for Pacinian corpuscles Hz and was not affected by block of C/Aδ-fibers in the ulnar nerve with resiniferatoxin, nor generated by direct stimulation of C/Aδ-fiber afferents with capsaicin. These findings suggest that HT7 inhibition of cocaine-induced locomotor activity is mediated by A-fiber activation of ulnar nerve that originates in superficial and deep tissue.

Full Text Available Background: One of the puerperal complication is uterine subinvolution that can cause bleeding to maternal death. Oxytocin massage can stimulate oxytocin hormone that plays a role in the process of uterine involution. Endorphine massage can increase the release of oxytocin and endorphine hormone that give a sense of calm and comfort. It also increases production of oxytocin hormone that can improve the process of uterine involution. Objective: To prove the effectiveness of a combination of oxytocin massage and endorphine massage to uterine involution in primiparaous mothers during postpartum period. Methods: This was a quasy-experimental study with pretest-posttest with control group design. Total samples were 44 normal postpartum mothers selected using purposive sampling technique, which were randomly assigned in four groups, namely: 1 oxytocin massage group, 2 endorphin massage group, 3 combined oxytocin-endorphin massage group, and 4 control group. The data were analyzed using univariate, bivariate and One Way Anova to test the effectiveness of the intervention. Results: There were statistically significant differences of fundal height before and after intervention among the four groups (p=<0.05. Conclusion: The combination of oxytocin massage and endorphine massage proved most effective in accelerating uterine involution in normal postpartum mothers.

Acupuncture as a Complementary Method of Traditional Psoriasis Treatment: Myth or Reality?

acupuncture for psoriasis treatment with an increasing number of people achieving clinical and statistical improvements. Furthermore, Wang et al. (8) have recently published the protocol for a systematic review which aims to assess the effectiveness and safety of acupuncture for patients with psoriasis. In acupuncture, hair-thin needles are inserted into the skin, releasing natural pain killers such as adenosine, endorphins, and serotonin into the body. It is known that patients with psoriatic arthritis can benefit from the treatment. Some patients may be concerned that acupuncture needles could worsen a skin flare-up but an acupuncturist uses sterile needles to prevent any risk to flaring skin. The advantage of acupuncture is that it is a very safe alternative medicine treatment and is not likely to interfere with any existing psoriasis treatment. It is important to note that acupuncture is a 5000-year-old alternative medicine treatment and that it has been officially recognized by the WHO for more than three decades (5). After achieving clinical improvement and regression of psoriatic plaques during the acupuncture for headache, the authors reviewed the literature and found reports about possible benefits of treating psoriasis with acupuncture. Therefore, the purpose of this letter and case study is to raise awareness and inform dermatologists about the different and until now under-explored possibilities of acupuncture in treating psoriasis.

The study of the mechanism of acupuncture action was revolutionized by the use of functional magnetic resonance imaging (fMRI). Over the past decade, our fMRI studies of healthy subjects have contributed substantially to elucidating the central effect of acupuncture on the human brain. These studies have shown that acupuncture stimulation, when associated with sensations comprising deqi, evokes deactivation of a limbic-paralimbic-neocortical network, which encompasses the limbic system, as well as activation of somatosensory brain regions. These networks closely match the default mode network and the anti-correlated task-positive network described in the literature. We have also shown that the effect of acupuncture on the brain is integrated at multiple levels, down to the brainstem and cerebellum. Our studies support the hypothesis that the effect of acupuncture on the brain goes beyond the effect of attention on the default mode network or the somatosensory stimulation of acupuncture needling. The amygdala and hypothalamus, in particular, show decreased activation during acupuncture stimulation that is not commonly associated with default mode network activity. At the same time, our research shows that acupuncture stimulation needs to be done carefully, limiting stimulation when the resulting sensations are very strong or when sharp pain is elicited. When acupuncture induced sharp pain, our studies show that the deactivation was attenuated or reversed in direction. Our results suggest that acupuncture mobilizes the functionally anti-correlated networks of the brain to mediate its actions, and that the effect is dependent on the psychophysical response. In this work we also discuss multiple avenues of future research, including the role of neurotransmitters, the effect of different acupuncture techniques, and the potential clinical application of our research findings to disease states including chronic pain, major depression, schizophrenia, autism, and Alzheimer

Peripheral non-viral MIDGE vector-driven delivery of β-endorphin in inflammatory pain

Full Text Available Abstract Background Leukocytes infiltrating inflamed tissue produce and release opioid peptides such as β-endorphin, which activate opioid receptors on peripheral terminals of sensory nerves resulting in analgesia. Gene therapy is an attractive strategy to enhance continuous production of endogenous opioids. However, classical viral and plasmid vectors for gene delivery are hampered by immunogenicity, recombination, oncogene activation, anti-bacterial antibody production or changes in physiological gene expression. Non-viral, non-plasmid minimalistic, immunologically defined gene expression (MIDGE vectors may overcome these problems as they carry only elements needed for gene transfer. Here, we investigated the effects of a nuclear localization sequence (NLS-coupled MIDGE encoding the β-endorphin precursor proopiomelanocortin (POMC on complete Freund's adjuvant-induced inflammatory pain in rats. Results POMC-MIDGE-NLS injected into inflamed paws appeared to be taken up by leukocytes resulting in higher concentrations of β-endorphin in these cells. POMC-MIDGE-NLS treatment reversed enhanced mechanical sensitivity compared with control MIDGE-NLS. However, both effects were moderate, not always statistically significant or directly correlated with each other. Also, the anti-hyperalgesic actions could not be increased by enhancing β-endorphin secretion or by modifying POMC-MIDGE-NLS to code for multiple copies of β-endorphin. Conclusion Although MIDGE vectors circumvent side-effects associated with classical viral and plasmid vectors, the current POMC-MIDGE-NLS did not result in reliable analgesic effectiveness in our pain model. This was possibly associated with insufficient and variable efficacy in transfection and/or β-endorphin production. Our data point at the importance of the reproducibility of gene therapy strategies for the control of chronic pain.

To study the effect of electro-acupuncture (EA) at points along Foot Yangming Channel on metabolite of ulcerative colitis (UC) rats' cerebral cortex and to identify key metabolites by referring to Pi/Wei-brain related theory in Chinese medicine (CM). The UC rat model was set up by dextran sulfate sodium (DSS) method. Male SD rats were randomly divided into the model group and the EA group, 13 in each group. Another 13 rats were recruited as the blank control group. Rats in the blank control group and the model group received no EA. EA was performed at Zusanli (ST36), Shangjuxu (ST37), and Tianshu (ST25) for 5 days by using disperse-dense wave. Then all rats were sacrificed. Their recto-colon and the ileocecal junction were pathomorphologically observed by light microscope and transmission electron microscope (TEM). Cerebral cortexes were extracted. Water-soluble and lipid-soluble brain tissue metabolites were respectively extracted for metabolic research using 1H nuclear magnetic resonance (1H-NMR). EA could obviously improve the general condition of UC model rats, decrease the value of DAI, reduce the infiltration of inflammatory cells in the intestinal tract, stabilize structures such as mitochondria, endoplasmic reticulum and so on (P theory.

To study the changes of cognitive attention-related brain function in the heroin addicts before and after electro-acupuncture (EA) intervention for exploring the concerned neuro-mechanism of addictive relapse and the central action role of EA intervention. Adopting event-related potential (ERP) technique, the ERP at 64 electrode spots in 10 heroin addicts (test group) were recorded before and after EA intervention with dot-probe experimental form during implementing cognitive task on positive emotional clue (PEC), negative emotional clues (NEC), and heroin-related clue (HRC). The P200 amplitude components on the selected observation points (Fz, Cz, and Pz) were analyzed and compared with those obtained from 10 healthy subjects as the control. Before EA, the ERP of attention on HRC in the test group was higher than that on PEC and NEC (Pattention on HRC at Cz and Pz was significantly lowered (P PEC > HRC, but in the control group, it showed PEC > HRC at all three observation points and PEC > NEC at Pz. Heroin addicts show attention bias to HRC, which could be significantly reduced by EA intervention, illustrating that EA could effectively inhibit the attention bias to heroin and so might have potential for lowering the relapse rate.

1 The spasmogenic and spasmolytic effects of beta-lipotropin (LPH) fragments and one analogue were investigated on different parts of the gastro-intestinal tract of guinea-pig and rat in vitro.2 Changes in muscle tone were observed in colon and rectum and to a lesser extent in jejunum and ileum of both species. Rat colon and rectum contracted to the peptides. Guinea-pig colon and rectum relaxed after an initial short-lasting contraction.3 On the rat rectum (D-ala(2))met-enkephalin, leu-enkephalin, gamma-endorphin, alpha-endorphin and beta-LPH 80-91 caused dose-dependent contractions, their ED(50) values being 0.96 x 10(-12) mol, 1.05 x 10(-11) mol, 1.22 x 10(-11) mol, 1.08 x 10(-10) mol, 2.65 x 10(-10) mol and 6.5 x 10(-9) mol, respectively.4 Naloxone dose-dependently shifted the dose-response curve of met-enkephalin to the right. Atropine, hexamethonium, burimamide, mepyramine, propranolol and indomethacin did not influence the response to met-enkephalin.5 In the presence of tetrodotoxin, the ED(50) for met-enkephalin and the maximal contractor response induced by met-enkephalin, appeared to be increased.6 The 5-hydroxytryptamine (5-HT) antagonists, methysergide and cyproheptadine, reduced the contractor response in a non-competitive manner. The alpha-adrenoceptor antagonist phentolamine, in contrast, caused an increase of the maximal response to met-enkephalin of up to 200%. Noradrenergic and tryptaminergic systems, therefore, might be involved in the changes in muscle tone induced by met-enkephalin.7 These results demonstrate that rectum and colon of guinea-pig and rat are very sensitive to opioid-like peptides.

Invasin of Yersinia pseudotuberculosis binds to beta1-integrins on host cells and triggers internalization of the bacterium. To elucidate the mechanism behind the beta1-integrin-mediated internalization of Yersinia, a beta1-integrin-deficient cell line, GD25, transfected with wild-type beta1A, beta......1B or different mutants of the beta1A subunit was used. Both beta1A and beta1B bound to invasin-expressing bacteria, but only beta1A was able to mediate internalization of the bacteria. The cytoplasmic region of beta1A, differing from beta1B, contains two NPXY motifs surrounding a double threonine...... noted that cells affected in bacterial internalization exhibited reduced spreading capability when seeded onto invasin, suggesting a correlation between the internalization of invasin-expressing bacteria and invasin-induced spreading. Likewise, integrins defective in forming peripheral focal complex...

Acupuncture is promoted as a treatment for smoking cessation, and is believed to reduce withdrawal symptoms. The objective of this review is to determine the effectiveness of acupuncture in smoking cessation in comparison with: a) sham acupuncture b) other interventions c) no intervention. We searched the Cochrane Tobacco Addiction Group trials register, Medline, PsycLit, Dissertation Abstracts, Health Planning and Administration, Social SciSearch, Smoking & Health, Embase, Biological Abstracts and DRUG. Randomised trials comparing a form of acupuncture with either sham acupuncture, another intervention or no intervention for smoking cessation. We extracted data in duplicate on the type of subjects, the nature of the acupuncture and control procedures, the outcome measures, method of randomisation, and completeness of follow-up. We assessed abstinence from smoking at the earliest time-point (before 6 weeks), at six months and at one year follow-up in patients smoking at baseline. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Those lost to follow-up were counted as continuing to smoke. Where appropriate, we performed meta-analysis using a fixed effects model. We identified 18 publications involving 20 comparisons. Acupuncture was not superior to sham acupuncture in smoking cessation at any time point. The odds ratio (OR) for early outcomes was 1.22 (95% confidence interval 0.99 to 1.49); the OR after 6 months was 1.38 (95% confidence interval 0.90 to 2.11) and after 12 months 1.02 (95% confidence interval 0.72 to 1.43). Similarly, when acupuncture was compared with other anti-smoking interventions, there were no differences in outcome at any time point. Acupuncture appeared to be superior to no intervention in the early results, but this difference was not sustained. The results with different acupuncture techniques do not show any one particular method (i.e. auricular acupuncture or non

Ethanol injected into the hypothalamic arcuate nucleus induces behavioral stimulation in rats: an effect prevented by catalase inhibition and naltrexone.

Science.gov (United States)

Pastor, Raúl; Aragon, Carlos M G

It is suggested that some of the behavioral effects of ethanol, including its psychomotor properties, are mediated by beta-endorphin and opioid receptors. Ethanol-induced increases in the release of hypothalamic beta-endorphin depend on the catalasemic conversion of ethanol to acetaldehyde. Here, we evaluated the locomotor activity in rats microinjected with ethanol directly into the hypothalamic arcuate nucleus (ArcN), the main site of beta-endorphin synthesis in the brain and a region with high levels of catalase expression. Intra-ArcN ethanol-induced changes in motor activity were also investigated in rats pretreated with the opioid receptor antagonist, naltrexone (0-2 mg/kg) or the catalase inhibitor 3-amino-1,2,4-triazole (AT; 0-1 g/kg). We found that ethanol microinjections of 64 or 128, but not 256 microg, produced locomotor stimulation. Intra-ArcN ethanol (128 microg)-induced activation was prevented by naltrexone and AT, whereas these compounds did not affect spontaneous activity. The present results support earlier evidence indicating that the ArcN and the beta-endorphinic neurons of this nucleus are necessary for ethanol to induce stimulation. In addition, our data suggest that brain structures that, as the ArcN, are rich in catalase may support the formation of ethanol-derived pharmacologically relevant concentrations of acetaldehyde and, thus be of particular importance for the behavioral effects of ethanol.

Maternal venous plasma concentrations of beta-LPH, beta-EP and gamma-LPH were compared in (i) patients undergoing vaginal delivery, 11 with an epidural block and 13 with pethidine and nitrous oxide or no analgesics; (ii) patients delivered by caesarean section, 7 under epidural block and 8 under general anaesthesia. Patients delivered by either method under epidural block had significantly lower levels of all three peptides than those receiving no epidural. There were significant negative correlations between umbilical vein beta-LPH, beta-EP and gamma-LPH concentrations and umbilical artery pH and positive correlations between beta-LPH and beta-EP but not gamma-LPH and cord PCO2 in 29 patients. There was no relation between cord levels of any of the three peptides and the method of analgesia or the route of delivery. Although concentrations of all three peptides were closely correlated to one another in either maternal or cord plasma, there was no relationship between maternal and fetal levels.

History of acupuncture research.

2013-01-01

The acupuncture has been practiced in China for more than 3000 years and was spread to Europe and American from the sixteenth to the nineteenth century. The history of acupuncture research was initiated in the eighteenth century and developed rapidly since then. In the past, physicians tried hard to apply acupuncture into clinical practice, while scientists were focused on the possible characteristics of acupoints and meridians. In the modern time, scientists have strived hard to evaluate the real effectiveness of acupuncture and the underlying physiological and biological mechanisms of acupuncture. Reviewing research history from past to present, we are delighted to witness this wonderful development. Accumulated evidences that acupuncture is beneficial in various conditions significantly enhanced our understanding the mechanisms of acupuncture treatment. However, there is still no conclusive evidence in acupuncture clinical studies. The clinical research still needs great improving, while the basic research results need to be appropriately transformed into clinical outcomes. Based on current achievements, we believe that although the challenges and difficulties exist, a more collaborative, innovative, and integrated approach will help us to achieve further progress in future acupuncture research. © 2013 Elsevier Inc.

Thyroid hormone deficiency has been reported to decrease expression and function of both beta(1)- and beta(2)-adrenoceptor in different tissues including heart. The purpose of this study was to examine the possible contribution of beta(3)-adrenoceptors to cardiac dysfunction in hypothyroidism. In addition, effect of this pathology on beta(1)- and beta(2)-adrenoceptor was investigated. Hypothyroidism was induced by adding methimazole (300 mg/l) to drinking water of rats for 8 weeks. Cardiac hemodynamic parameters were measured in anesthetised rats in vivo. Responses to beta-adrenoceptor agonists were examined in rat papillary muscle in vitro. We also studied the effect of hypotyroidism on mRNA expression of beta-adrenoceptors, Gialpha, GRK, and eNOS in rat heart. All of the hemodynamic parameters (systolic, diastolic and mean arterial pressure, left ventricular pressure, heart rate, +dp/dt, and -dp/dt) were significantly reduced by the methimazole treatment. The negative inotropic effect elicited by BRL 37344 (a beta(3)-adrenoceptor preferential agonist) and positive inotropic effects produced by isoprenaline and noradrenaline, respectively, were significantly decreased in papillary muscle of hypothyroid rats as compared to those of controls. On the other hand, hypothyroidism resulted in increased cardiac beta(2)- and beta(3)-adrenoceptor, Gialpha(2), Gialpha(3), GRK3, and eNOS mRNA expressions. However, beta(1)-adrenoceptor and GRK2 mRNA expressions were not changed significantly in this pathology. These results show that mRNA expression of beta(3)-adrenoceptors as well as the signalling pathway components mediated through beta(3)-adrenoceptors are significantly increased in hypothyroid rat heart. Since we could not correlate these alternates with the decreased negative inotropic response mediated by this receptor subtype, it is not clear whether these changes are important for hypothyroid induced reduction in cardiac function.

Background Although acupuncture sensation (also known as de qi) is a cornerstone of traditional acupuncture therapy, most research has accepted the traditional method of defining acupuncture sensation only through subjective patient reports rather than on any quantifiable physiological basis. Purpose To preliminarily investigate the frequency of key sensations experienced while needling to specific, quantifiable tissue levels (TLs) guided by ultrasound (US) imaging. Methods Five participants received needling at two acupuncture points and two control points at four TLs. US scans were used to determine when each TL was reached. Each volunteer completed 32 sets of modified Southampton Needle Sensation Questionnaires. Part one of the study tested sensations experienced at each TL and part two compared the effect of oscillation alone versus oscillation + rotation. Results In all volunteers, the frequency of pricking, sharp sensations was significantly greater in shallower TLs than deeper (p=0.007); the frequency of sensations described as deep, dull and heavy, as spreading, and as electric shocks was significantly greater in deeper TLs than shallower (p=0.002). Sensations experienced did not significantly differ between real and control points within each of three TLs (p>0.05) except TL 4 (p=0.006). The introduction of needle rotation significantly increased deep, dull, heavy sensations, but not pricking and sharp sensations; within each level, the spectrum of sensation experienced during both oscillation + rotation and oscillation alone did not significantly differ between acupuncture and control points. Conclusion The preliminary study indicates a strong connection between acupuncture sensation and both tissue depth and needle rotation. Furthermore, the new methodology has been proven feasible. A further study with an objective measurement is warranted. PMID:21642648

Despite some evidence that indicates that the evolution of polycystic ovary syndrome (PCOS) is related to the activity of the endogenous opioid system, and that concentration of plasma β-endorphin levels can increase pain threshold, there are no studies which evaluate pressure pain threshold in the PCOS women population. In 48 lean women with PCOS and 38 lean women without this disorder plasma β-endorphins and PPT were measured. The β-endorphins level was higher in the PCOS group compared to the controls (15.28±2.49 pg/mL vs. 6.33±1.71 pg/mL, PPCOS group PPTs measured on deltoid and trapezius muscles were higher compared to the controls (9.33±1.3 kg/cm² vs. 5.19±0.57 kg/cm², PPCOS group. Increase in β-endorphin level of 1 pg/mL was associated with increase of PPT value on deltoid muscle of 0.23 kg/cm² (R=0.632, P=0.011) and of 0.18 kg/cm² on trapezius muscle (R=0.588, P=0.037). There were no correlations between testosterone level and PPT in PCOS group. β-endorphin serum level as well as PPT are higher in lean PCOS group than in controls. We found correlations between β-endorphin levels and PPT in the PCOS group. It may suggest the role of endogenous opioids in the pathogenesis of PCOS and also that the increases in circulating plasma β-endorphins concentration can increases PPT in this group.

There are many eminent acupuncture masters in modern times in the regions of Zhejiang province, which has developed the acupuncture schools of numerous characteristics and induces the important impacts at home and abroad. Through the literature collection on the acupuncture schools in Zhejiang and the interviews to the parties involved, it has been discovered that the acupuncture manipulation techniques of acupuncture masters in modern times are specifically featured. Those techniques are developed on the basis of Neijing (Internal Classic), Jinzhenfu (Ode to Gold Needle) and Zhenjiu Dacheng (Great Compendium of Acupuncture and Moxibustion). No matter to obey the old maxim or study by himself, every master lays the emphasis on the research and interpretation of classical theories and integrates the traditional with the modern. In the paper, the acupuncture manipulation techniques of Zhejiang acupuncture masters in modern times are stated from four aspects, named needling techniques in Internal Classic, feijingzouqi needling technique, penetrating needling technique and innovation of acupuncture manipulation.

Cue-induced cocaine craving intensifies, or ‘incubates', during the first few weeks of abstinence and persists over extended periods of time. One important factor implicated in cocaine addiction is the endogenous opioid β-endorphin. In the present study, we examined the possible involvement of β-endorphin in the incubation of cocaine craving. Rats were trained to self-administer cocaine (0.75 mg/kg, 10 days, 6 h/day), followed by either a 1-day or a 30-day period of forced abstinence. Subsequent testing for cue-induced cocaine-seeking behavior (without cocaine reinforcement) was performed. Rats exposed to the drug-associated cue on day 1 of forced abstinence demonstrated minimal cue-induced cocaine-seeking behavior concurrently with a significant increase in β-endorphin release in the nucleus accumbens (NAc). Conversely, exposure to the cue on day 30 increased cocaine seeking, while β-endorphin levels remained unchanged. Intra-NAc infusion of an anti-β-endorphin antibody (4 μg) on day 1 increased cue-induced cocaine seeking, whereas infusion of a synthetic β-endorphin peptide (100 ng) on day 30 significantly decreased cue response. Both intra-NAc infusions of the δ opioid receptor antagonist naltrindole (1 μg) on day 1 and naltrindole together with β-endorphin on day 30 increased cue-induced cocaine-seeking behavior. Intra-NAc infusion of the μ opioid receptor antagonist CTAP (30 ng and 3 μg) had no behavioral effect. Altogether, these results demonstrate a novel role for β-endorphin and the δ opioid receptor in the development of the incubation of cocaine craving. PMID:23800967

This review (along with a companion review on 'Acupuncture for tension-type headache' represents an updated version of a Cochrane review originally published in Issue 1, 2001, of The Cochrane Library. OBJECTIVES: To investigate whether acupuncture is a more effective than no prophylactic treatment/routine care only; b more effective than 'sham' (placebo acupuncture; and c as effective as other interventions in reducing headache frequency in patients with migraine. METHODS: Search methods: The Cochrane Pain, Palliative & Supportive Care Trials Register, CENTRAL, MEDLINE, EMBASE and the Cochrane Complementary Medicine Field Trials Register were searched to January 2008. Selection criteria: We included randomized trials with a post-randomization observation period of at least 8 weeks that compared the clinical effects of an acupuncture intervention with a control (no prophylactic treatment or routine care only, a sham acupuncture intervention or another intervention in patients with migraine. Data collection and analysis: Two reviewers checked eligibility; extracted information on patients, interventions, methods and results; and assessed risk of bias and quality of the acupuncture intervention. Outcomes extracted included response (outcome of primary interest, migraine attacks, migraine days, headache days and analgesic use. Pooled effect size estimates were calculated using a random-effects model. MAIN RESULTS: Twenty-two trials with 4419 participants (mean 201, median 42, range 27 to 1715 met the inclusion criteria. Six trials (including two large trials with 401 and 1715 patients compared acupuncture to no prophylactic treatment or routine care only. After 3 to 4 months patients receiving acupuncture had higher response rates and fewer headaches. The only study with long-term follow up saw no evidence that effects dissipated up

Possible role of epidermal keratinocytes in the construction of acupuncture meridians.

Science.gov (United States)

Denda, Mitsuhiro; Tsutsumi, Moe

2014-04-01

Acupuncture meridians consist of a network of acupuncture points on the skin, stimulation of which is well established to have a variety of physiological effects. We have previously demonstrated that epidermal keratinocytes contain multiple sensory systems for temperature, mechanical stimuli, electric potentials and other stimuli. These sensory systems generate changes in the calcium-ion concentration in the epidermis, so epidermal keratinocytes can generate spatially-localized electro-physiological patterns in the skin. We have previously demonstrated signaling between epidermal keratinocytes and peripheral nerve systems. Therefore, stimuli sensed by epidermal keratinocytes might be transferred to the unmyelinated nerve fibers that are known to exist in the epidermis and, thence, to the spinal cord and brain. We propose that epidermal keratinocytes form an information-gathering network in the skin and that this network plays a key role in whole-body homeostasis in response to the changing environment. We also hypothesize that this network corresponds to the acupuncture meridians. As supporting examples, we present some striking calcium propagation patterns observed in cultured human keratinocytes after adenosine-triphosphate (ATP) stimulation. These results support the ideas that keratinocytes can generate spatially-restricted signaling patterns after environmental stimulation and that the cultures might be in-vitro models of meridians as an information-gathering network in skin.

The development status of acupuncture and moxibustion in Tunisia is introduced in this article. Although acupuncture and moxibustion only has a history of more than 30 years in Tunisia, it is very popular among the local people. Until now, there is one acupuncture and moxibustion center aided and built with the help of the Chinese government. Acupuncture and moxibustion clinical department has been set in some of the hospitals, and acupuncture and moxibustion clinical practice is also carried out in some private clinics. Cost of acupuncture and moxibustion in public hospitals has already been covered by medical insurance. As for education of acupuncture and moxibustion, training courses were set up in medical colleges of Tunisia by Tunisian government which is lectured by Chinese acupuncture experts. Acupuncture and moxibustion has been used to treat many diseases in Tunisia and is warmly welcomed by Tunisian.

Review of Clinical Applications of Scalp Acupuncture for Paralysis: An Excerpt From Chinese Scalp Acupuncture

Science.gov (United States)

Hao, Linda Lingzhi

2012-01-01

Chinese scalp acupuncture is a contemporary acupuncture technique integrating traditional Chinese needling methods with Western medical knowledge of representative areas of the cerebral cortex. It has been proven to be a most effective technique for treating acute and chronic central nervous system disorders. Scalp acupuncture often produces remarkable results with just a few needles and usually brings about immediate improvement, sometimes taking only several seconds to a minute. Acupuncture, a therapeutic technique of Oriental Medicine, can be traced back more than 2500 years. Throughout its long history, acupuncture has evolved as its own unique traditional medicine. By embracing newly developed knowledge and technology, the profession continues to create additional methods of treatment. Techniques such as electrical and laser acupuncture and even new acupuncture points are currently being developed. We believe scalp acupuncture, which integrates Western medicine with Traditional Chinese Medicine, to be the most significant development that Chinese acupuncture has made in the past 60 years.

Some methodic aspects in optimizing the radioimmunoassay of β-endorphin

International Nuclear Information System (INIS)

Rueckert, R.I.; Hoffmann, Y.; Rohde, W.

1986-01-01

A specific double antibody radioimmunoassay (RIA) for human β-endorphin (β-EP) using an antibody to synthetic β/sub h/-endorphin was established. This antibody cross-reacted with β-lipotropin (β-LPH) at 42% on molar basis and allowed a usable range of 20 pg to 4 ng of β-endorphin per ml in the assay. Comparing the efficiency of the conventional extraction procedures under various conditions using Corning glass, Vycor glass, QUSO G-32, silicic acid and controlled pore glass 75, the optimal result was obtained by Corning glass, with a recovery rate of more than 80%. The most simple and rapid method with an extraction efficiency of more than 90% was found to be the extraction by use of Sep-Pak C18 cartridges. The separation of β-EP from β-LPH was studied using Sephadex G-50, G-75, G-100 and Bio-Gel P-60 columns and different elution media. The use of a Sephadex G-50 column (0.9 x 55 cm) and elution with 0.1 N acetic acid-0.05% HSA gave the best result. The reliability of the radioimmunoassay was shown under physiological and pathophysiological conditions. (author)

Full Text Available Aim: To investigate the effects of training sessions on circulating β-endorphin changes in sport horses before and after competition and to ascertain whether competition would affect this response. Materials and Methods: A total of 24 trained jumping horses were randomly assigned to one of two training groups: Group A (competing and Group B (not competing. To determined plasma β-endorphin concentrations, two pre- and postcompetition training weeks at aerobic workout and two competitive show jumping event days at anaerobic workout were measured before, 5 and 30 min after exercise. Exercise intensity is described using lactate concentrations and heart rate. The circuit design, intensity, and duration of training sessions were the same for both groups. Results: In Group A, one-way analysis of variance for repeated measures (RM-ANOVA showed significant effects of exercise on β-endorphin changes (F=14.41; p<0.001, only in the post-competition training sessions, while in Group B showed no significant effects. Two-way RM-ANOVA showed, after post-competition training sessions, a significant difference between Group A and Group B (F=6.235; p=0.023, with higher β-endorphin changes in Group A, compared to Group B. During the competitive show jumping sessions, one-way RM ANOVA showed significant effects of exercise on β-endorphin changes (F=51.10; p<0.001. The statistical analysis, in Group A, showed a significant difference between postcompetition training and competitive exercise (F=6.32; p=0.024 with higher β-endorphin values in competitive sessions compared to those of post-competition training. Conclusion: Lactate concentrations seem to be the main factors being correlated with the raise of β-endorphin during anaerobic exercise of competitive events. Exercise of low intensity, as well as that one of training sessions, does not appear to stimulate a significant increased release of β-endorphin and it may depend on the duration of the exercise

Functional dyspepsia (FD) has been a worldwide complaint. More effective therapies are needed with fewer adverse effects than are seen with conventional medications. Acupuncture, as a traditional therapeutic method, has been widely used for functional gastrointestinal disorders in the East. Manual acupuncture and electroacupuncture have been recognized treatments for FD, but to date, no robust evidence has been found for the effectiveness and safety of these interventions in the treatment of this condition. This review was conducted to assess the efficacy and safety of manual acupuncture and electroacupuncture in the treatment of FD. Trials meeting the inclusion criteria were identified through electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Allied and Complementary Medicine Database (AMED), Chinese Biology Medicine Disc (CBMdisc), China National Knowledge Infrastructure (CNKI), the Wanfang Database, the VIP Database, and six trial registries. Handsearching was done to screen the reference sections of potential trials and reviews. Randomized controlled trials (RCTs) were included if investigators reported efficacy and safety of manual acupuncture or electroacupuncture for patients with FD diagnosed by Rome II or Rome III criteria, compared with medications, blank control, or sham acupuncture. Data were extracted by independent review authors. Study limitations were assessed by using the tool of The Cochrane Collabration for assessing risk of bias. For dichotomous data, risk ratios (RRs) and 95% confidence intervals (95% CIs) would be applied, and for continuous data, mean differences (MDs) and 95% CIs. A fixed-effect model was applied in the meta-analysis, or a descriptive analysis was performed. The quality of evidence for the outcome measure was assessed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. Seven studies were included in the review, involving 542

2017-10-17

This is one of a series of reviews of methods of cervical ripening and labour induction. The use of complementary therapies is increasing. Women may look to complementary therapies during pregnancy and childbirth to be used alongside conventional medical practice. Acupuncture involves the insertion of very fine needles into specific points of the body. Acupressure is using the thumbs or fingers to apply pressure to specific points. The limited observational studies to date suggest acupuncture for induction of labour has no known adverse effects to the fetus, and may be effective. However, the evidence regarding the clinical effectiveness of this technique is limited. To determine, from the best available evidence, the effectiveness and safety of acupuncture and acupressure for third trimester cervical ripening or induction of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2016), PubMed (1966 to 25 November 2016), ProQuest Dissertations & Theses (25 November 2016), CINAHL (25 November 2016), Embase (25 November 2016), the WHO International Clinical Trials Registry Portal (ICTRP) (3 October 2016), and bibliographies of relevant papers. Randomised controlled trials comparing acupuncture or acupressure, used for third trimester cervical ripening or labour induction, with placebo/no treatment or other methods on a predefined list of labour induction methods. Two review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy. The quality of the evidence was assessed using GRADE. This updated review includes 22 trials, reporting on 3456 women. The trials using manual or electro-acupuncture were compared with usual care (eight trials, 760 women), sweeping of membranes (one trial, 207 women), or sham controls (seven trials, 729 women). Trials using acupressure were compared with usual care (two trials, 151 women) or sham controls (two trials, 239 women). Many studies

Individual patient data meta-analysis of acupuncture for chronic pain: protocol of the Acupuncture Trialists' Collaboration

Directory of Open Access Journals (Sweden)

Sherman Karen J

2010-09-01

Full Text Available Abstract Background The purpose of clinical trials of acupuncture is to help clinicians and patients make decisions about treatment. Yet this is not straightforward: some trials report acupuncture to be superior to sham (placebo acupuncture while others show evidence that acupuncture is superior to usual care but not sham, and still others conclude that acupuncture is no better than usual care. Meta-analyses of these trials tend to come to somewhat indeterminate conclusions. This appears to be because, until recently, acupuncture research was dominated by small trials of questionable quality. The Acupuncture Trialists' Collaboration, a group of trialists, statisticians and other researchers, was established to synthesize patient-level data from several recently published large, high-quality trials. Methods There are three distinct phases to the Acupuncture Trialists Collaboration: a systematic review to identify eligible studies; collation and harmonization of raw data; statistical analysis. To be eligible, trials must have unambiguous allocation concealment. Eligible pain conditions are osteoarthritis; chronic headache (tension or migraine headache; shoulder pain; and non-specific back or neck pain. Once received, patient-level data will undergo quality checks and the results of prior publications will be replicated. The primary analysis will be to determine the effect size of acupuncture. Each trial will be evaluated by analysis of covariance with the principal endpoint as the dependent variable and, as covariates, the baseline score for the principal endpoint and the variables used to stratify randomization. The effect size for acupuncture from each trial - that is, the coefficient and standard error from the analysis of covariance - will then be entered into a meta-analysis. We will compute effect sizes separately for comparisons of acupuncture with sham acupuncture, and acupuncture with no acupuncture control for each pain condition. Other

The topographic structures of acupuncture points were investigated by using the synchrotron radiation based Dark Field Image (DFI) method. Four following acupuncture points were studied: Sanyinjiao, Neiguan, Zusanli and Tianshu. We have found that at acupuncture point regions there exists the accumulation of micro-vessels. The images taken in the surrounding tissue out of the acupuncture points do not show such kind of structure. It is the first time to reveal directly the specific structure of acupuncture points by X-ray imaging.

Auricular acupuncture is a method which has been successfully used in various fields of medicine especially in the treatment of pain relief. The introduction of lasers especially low-level lasers into medicine brought besides the already existing stimulation with needles and electricity an additional technique to auricular acupuncture. This literature research looks at the historical background, the development and the anatomical and neurological aspects of auricular acupuncture in general and auricular laser acupuncture in detail. Preliminary scientific findings on auricular acupuncture with laser have been described in detail and discussed critically in this review article. The results of the studies have shown evidence of the effect of auricular laser acupuncture. However, a comparison of these studies was impossible due to their different study designs. The most important technical as well as study parameters were described in detail in order to give more sufficient evidence and to improve the quality of future studies. PMID:23935695

Endogenous Opiates in the Nucleus Tractus Solitarius Mediate Electroacupuncture-Induced Sleep Activities in Rats

Directory of Open Access Journals (Sweden)

Chiung-Hsiang Cheng

2011-01-01

Full Text Available Electroacupuncture (EA possesses various therapeutic effects, including alleviation of pain, reduction of inflammation and improvement of sleep disturbance. The mechanisms of EA on sleep improvement, however, remain to be determined. It has been stated in ancient Chinese literature that the Anmian (EX17 acupoint is one of the trigger points that alleviates insomnia. We previously demonstrated that EA stimulation of Anmian acupoints in rats during the dark period enhances non-rapid eye movement (NREM sleep, which involves the induction of cholinergic activity in the nucleus tractus solitarius (NTS. In addition to cholinergic activation of the NTS, activation of the endogenous opioidergic system may also be a mechanism by which acupuncture affects sleep. Therefore, this study was designed to investigate the involvement of the NTS opioidergic system in EA-induced alterations in sleep. Our present results indicate that EA of Anmian acupoints increased NREM sleep, but not rapid eye movement sleep, during the dark period in rats. This enhancement in NREM sleep was dose-dependently blocked by microinjection of opioid receptor antagonist, naloxone, and the μ-opioid receptor antagonist, naloxonazine, into the NTS; administrations of δ-receptor antagonist, natrindole, and the κ-receptor antagonist, nor-binaltrophimine, however, did not affect EA-induced alterations in sleep. Furthermore, β-endorphin was significantly increased in both the brainstem and hippocampus after the EA stimuli, an effect blocked by administration of the muscarinic antagonist scopolamine into the NTS. Our findings suggest that mechanisms of EA-induced NREM sleep enhancement may be mediated, in part, by cholinergic activation, stimulation of the opiodergic neurons to increase the concentrations of β-endorphin and the involvement of the μ-opioid receptors.

The effect of Hegu acupoint stimulation in dental acupuncture analgesia

2007-03-01

Full Text Available In daily life, dental treatments are often related with oral pain sensation which needs anesthesia procedures. Sometimes local anesthetics can not be used because patients have hypersensitive reaction or systemic diseases which may lead to complications. Stimulating acupoint, such as Hegu activates hypothalamus and pituitary gland to release endogenous opioid peptide substances that reduce pain sensitivity. The aim of the study was to determine Hegu acupoint stimulation effect on the pain sensitivity reduction in maxillary central incisor gingiva. The laboratory experimental research was conducted on 12 healthy male Wistar rats (3 months old, weights 150–200 grams. All rat samples received the same treatments and adapted within 1 month. The research was done in pre and post test control group design. 40-Volt electro-stimulation was done once on the maxillary central incisor gingiva prior to the bilateral Hegu acupoint stimulation, then followed by 3 times electro-stimulation with 3 minutes intervals. The pain scores were obtained based on the samples’ contraction in each electro-stimulation. The responses were categorized into 5 pain scores and statistically analyzed using Wilcoxon Test. The results showed that Hegu acupoint stimulation lowered the pain scores significantly (p < 0.05. Hegu acupoint stimulation could reduce the pain sensitivity in maxillary central incisor gingiva. Therefore, the use of acupuncture analgesia in dental pain management can be considered in the future.

Background Acupuncture is a popular complementary and alternative treatment for chronic back pain. Recent European trials suggest similar short-term benefits from real and sham acupuncture needling. This trial addresses the importance of needle placement and skin penetration in eliciting acupuncture effects for patients with chronic low back pain. Methods 638 adults with chronic mechanical low back pain were randomized to: individualized acupuncture, standardized acupuncture, simulated acupuncture, or usual care. Ten treatments were provided over 7 weeks by experienced acupuncturists. The primary outcomes were back-related dysfunction (Roland Disability score, range: 0 to 23) and symptom bothersomeness (0 to 10 scale). Outcomes were assessed at baseline and after 8, 26 and 52 weeks. Results At 8 weeks, mean dysfunction scores for the individualized, standardized, and simulated acupuncture groups improved by 4.4, 4.5, and 4.4 points, respectively, compared with 2.1 points for those receiving usual care (P0.05). Conclusions Although acupuncture was found effective for chronic low back pain, tailoring needling sites to each patient and penetration of the skin appear to be unimportant in eliciting therapeutic benefits. These findings raise questions about acupuncture’s purported mechanisms of action. It remains unclear whether acupuncture, or our simulated method of acupuncture, provide physiologically important stimulation or represent placebo or non-specific effects. PMID:19433697

Protein kinase A (PKA)/cAMP response element-binding (CREB) protein signaling pathway, contributing to impaired neurogenesis parallel to depressive-like behaviors, has been identified as the crucial factor involved in the antidepressant response of acupuncture. However, the molecular mechanisms associated with antidepressant response of acupuncture, neurogenesis, and depressive-like behaviors ameliorating remain unexplored. The objective was to identify the mechanisms underlying the antidepressant response of acupuncture through PKA signaling pathway in depression rats by employing the PKA signaling pathway inhibitor H89 in in vivo experiments. Our results indicated that the expression of hippocampal PKA- α and p-CREB was significantly downregulated by chronic unpredicted mild stress (CUMS) procedures. Importantly, acupuncture reversed the downregulation of PKA- α and p-CREB. The expression of PKA- α was upregulated by fluoxetine, but not p-CREB. No significant difference was found between Acu and FLX groups on the expression of PKA- α and p-CREB. Interestingly, H89 inhibited the effects of acupuncture or fluoxetine on upregulating the expression of p-CREB, but not PKA- α . There was no significant difference in expression of CREB among the groups. Conclusively, our findings further support the hypothesis that acupuncture could ameliorate depressive-like behaviors by regulating PKA/CREB signaling pathway, which might be mainly mediated by regulating the phosphorylation level of CREB.

β-lipotropin is the major opioid-like peptide of human pituitary and rat pars distalis: lack of significant β-endorphin

β-Lipotropin is the predominant opioid peptide of the human pituitary and rat pars distalis and is present in concentrations essentially equimolar with corticotropin. When freshly obtained nonfrozen rat anterior pituitaries were homogenized with 0.2 M HCl, approximately 98% of the immunoreactivity detected utilizing an antiserum that crossreacts equally with β-lipotropin and β-endorphin coeluted with 125 I-labeled human β-lipotropin upon molecular sieve chromatography. The remainder of the activity eluted with synthetic human β-endorphin. Similar results were obtained for human pituitary. HCl homogenization of thawed tissue or homogenization of fresh tissue with acetic acid yielded substantially greater concentrations of β-endorphin and decreased concentrations of β-lipotropin. In human subjects, acute anterior pituitary stimulation using either insulin-induced hypoglycemia or vasopressin administration was associated with increased plasma β-lipotropin and corticotropin levels. At the time of peak concentrations, no significant levels of β-endorphin were detectable. These data indicate the lack of significant amounts of β-endorphin in human pituitary. Additionally, there appears to be no specific intrapituitary conversion of β-lipotropin to β-endorphin

Acupuncture is an oldest somato stimulus medical technique. As the most representative peripheral nerve stimulation therapy, it has a complete system of theory and application and is applicable to a large population. This paper expounds the bionic origins of acupuncture and analyzes the physiological mechanism by which acupuncture works. For living creatures, functionally sound viscera and effective endurance of pain are essential for survival. This paper discusses the way in which acupuncture increases the pain threshold of living creatures and the underlying mechanism from the perspective of bionics. Acupuncture can also help to adjust visceral functions and works most effectively in facilitating the process of digestion and restraining visceral pain. This paper makes an in-depth overview of peripheral nerve stimulation therapy represented by acupuncture. We look forward to the revival of acupuncture, a long-standing somato stimulus medicine, in the modern medical systems.

Previous work has shown that acupuncture stimulation evokes deactivation of a limbic-paralimbic-neocortical network (LPNN) as well as activation of somatosensory brain regions. This study explores the activity and functional connectivity of these regions during acupuncture vs. tactile stimulation and vs. acupuncture associated with inadvertent sharp pain. Acupuncture during 201 scans and tactile stimulation during 74 scans for comparison at acupoints LI4, ST36 and LV3 was monitored with fMRI and psychophysical response in 48 healthy subjects. Clusters of deactivated regions in the medial prefrontal, medial parietal and medial temporal lobes as well as activated regions in the sensorimotor and a few paralimbic structures can be identified during acupuncture by general linear model analysis and seed-based cross correlation analysis. Importantly, these clusters showed virtual identity with the default mode network and the anti-correlated task-positive network in response to stimulation. In addition, the amygdala and hypothalamus, structures not routinely reported in the default mode literature, were frequently involved in acupuncture. When acupuncture induced sharp pain, the deactivation was attenuated or became activated instead. Tactile stimulation induced greater activation of the somatosensory regions but less extensive deactivation of the LPNN. These results indicate that the deactivation of the LPNN during acupuncture cannot be completely explained by the demand of attention that is commonly proposed in the default mode literature. Our results suggest that acupuncture mobilizes the anti-correlated functional networks of the brain to mediate its actions, and that the effect is dependent on the psychophysical response.

A dispute about whether women are suitable to receive acupuncture treatment in the period of menstruation has existed for many years. There are some reports about acupuncture treatment induced abnormal menstruation in women experiencing menstruation. However, according to long-term clinical practice and current development of acupuncture therapy, the authors of the present paper hold that there are no absolute contradictions for acupuncture treatment of women during menstruation. Additionally, acupuncture induced menstrual disorder has no enough data support of large size example clinical trials. The key points of acupuncture administration for women during menstruation are: (1) reasonable selection of acupoints prescriptions, and (2) appropriate acupuncture needle manipulations, particularly avoiding strong stimulation.

Premenstrual dysphoric disorder (PMDD), a severe type of premenstrual syndrome (PMS), is characterized mainly by psychological symptoms confined to the premenstrual period, which reduce not only patients' quality of life, but also their working activities. Although various therapies have been employed for PMDD, some patients do not respond to them. We recently employed acupuncture treatment for a patient in PMDD. Symptoms ameliorated during the acupuncture (+) period, but deteriorated during the acupuncture (-) period. This review describes the clinical course of this case. The diagnosis and treatment of PMDD are briefly summarized and previous acupuncture treatment for PMS are reviewed. The difficulties in evaluating the effectiveness of acupuncture for PMS/PMDD are addressed. It is suggested that acupuncture may be a treatment option for PMDD.

Full Text Available ‘WHO Standard Acupuncture Point Locations in the Western Pacific Region (WHO Standard was released in 2008. Initially, there were 92/361 controversial acupuncture points (acupoints. Through seven informal consultations and four task force team meetings, 86 points were agreed upon among the 92 controversial acupoints, leaving 6 remaining controversial acupoints, demanding active research in the future. This will enhance the reproducibility and validity of acupuncture studies. It will also lead to a better understanding of acupuncture mechanisms in order to optimize its clinical efficacy for a range of diseases and syndromes. This book has two parts: General Guidelines for Acupuncture Point Locations and WHO Standard Acupuncture Point Locations. First of all, familiarity with the General Guidelines for Acupuncture Point Locations in this book can help the reader to understand and use the contents of this book in depth. I would like to thank all of the participating experts and scholars for this great work, who have overcome the limits of previous acupuncture references. I also appreciate the dedicated effort and harmonious leadership of Dr Choi Seung-hoon, former Regional Adviser in Traditional Medicine of Western Pacific Office, WHO.

Biotin uptake by mouse and human pancreatic beta cells/islets: a regulated, lipopolysaccharide-sensitive carrier-mediated process

Biotin is essential for the normal function of pancreatic beta cells. These cells obtain biotin from their surroundings via transport across their cell membrane. Little is known about the uptake mechanism involved, how it is regulated, and how it is affected by internal and external factors. We addressed these issues using the mouse-derived pancreatic beta-TC-6 cells and freshly isolated mouse and human primary pancreatic beta cells as models. The results showed biotin uptake by pancreatic beta-TC-6 cells occurs via a Na+-dependent, carrier-mediated process, that is sensitive to desthiobiotin, as well as to pantothenic acid and lipoate; the process is also saturable as a function of concentration (apparent Km = 22.24 ± 5.5 μM). These cells express the sodium-dependent multivitamin transporter (SMVT), whose knockdown (with doxycycline-inducible shRNA) led to a sever inhibition in biotin uptake. Similarly, uptake of biotin by mouse and human primary pancreatic islets is Na+-dependent and carrier-mediated, and both cell types express SMVT. Biotin uptake by pancreatic beta-TC-6 cells is also adaptively regulated (via transcriptional mechanism) by extracellular substrate level. Chronic treatment of pancreatic beta-TC-6 cells with bacterial lipopolysaccharides (LPS) leads to inhibition in biotin uptake. This inhibition is mediated via a Toll-Like receptor 4-mediated process and involves a decrease in membrane expression of SMVT. These findings show, for the first time, that pancreatic beta cells/islets take up biotin via a specific and regulated carrier-mediated process, and that the process is sensitive to the effect of LPS.

[History of acupuncture in India].

Bai, Xinghua

India and China are both featured with ancient civilization. During the communication between the two countries, the communication from Indian culture, especially Buddhism, to China was predominant, while communication from Chinese culture to India was rare. So it was with medical communication until the end of 1950s when acupuncture was introduced to India. In this article, the medical communication between India and China as well as the introduction of acupuncture to India were discussed, and the resulting phenomenon was analyzed. The introduction of acupuncture to India proved personnel exchange was not necessary to acupuncture communication, and several invisible factors, such as language, religion and culture tradition might be the reasons for foreign nations to accept acupuncture. Therefore, these factors should be valued in the future international communication of acupuncture.

Hyperthermic responses to central injections of some peptide and non-peptide opioids in the guinea-pig

Kandasamy, S. B.; Williams, B. A.

1983-01-01

The intracerebroventricular administration of prototype nonpeptide opioid receptor (mu, kappa, and sigma) agonists, morphine, ketocyclazocine, and N-allyl normetazocine and an agonist at both kappa and sigma receptors, pentazocine, was found to induce hyperthermia in guinea pigs. The similar administration of peptide opioids like beta endorphin, methionine endkephalin, leucine endkephaline, and several of their synthetic analogues was also found to cause hyperthermia. Only the liver-like transport system of the three anion transport systems (iodide, hippurate, and liver-like) present in the choroid plexus was determined to be important to the central inactivation of beta-endorphin and two synthetic analogues. Prostaglandins and norepinephrine (NE) as well as cAMP were not involved in peptide and nonpeptide opioid-induced hyperthermia. Naloxone-sensitive receptors were found to be involved in the induction of hyperthermia by morphine and beta-endorphin, while hyperthermic responses to ketocyclazocine, N-allyl normetazocine, pentazocine, Met-enkephalin, Leu-enkephalin, and two of the synthetic analogues were not antagonized by nalozone. The lack of antagonism of naloxone on pyrogen, arachidonic acid, PGE2, dibutyryl cAMP, and NE-induced hyperthermia shows that endogenous opioid peptides are not likely to be central mediators of the hyperthermia induced by these agents.

With growing use of acupuncture treatment in various clinical conditions, the question has been posed whether the reported effects reflect specific mechanisms of acupuncture or whether they represent placebo responses, as they often are similar in effect size and resemble similarities to placebo analgesia and its mechanisms. We reviewed the available literature for different placebos (sham procedures) used to control the acupuncture effects, for moderators and potential biases in respective clinical trials, and for central and peripheral mechanisms involved that would allow differentiation of placebo effects from acupuncture and sham acupuncture effects. While the evidence is still limited, it seems that biological differences exist between a placebo response, e.g. in placebo analgesia, and analgesic response during acupunture that does not occur with sham acupuncture. It seems advisable that clinical trials should include potential biomarkers of acupuncture, e.g. measures of the autonomic nervous system function to verify that acupuncture and sham acupuncture are different despite similar clinical effects.

Anabolic-androgenic steroids (AASs) are abused primarily in the context of intense exercise and for the purposes of increasing muscle mass as opposed to drug-induced euphoria. AASs also modulate the HPA axis and may increase the reinforcing value of exercise through changes to stress hormone and endorphin release. To test this hypothesis, 26 adult males drawn from a larger study on AAS use completed a progressive ratio task designed to examine the reinforcing value of exercise relative to financial reinforcer. Sixteen experienced and current users (8 on-cycle, 8 off-cycle) and 10 controls matched on quantity×frequency of exercise, age, and education abstained from exercise for 24 h prior to testing and provided 24-h cortisol, plasma cortisol, ACTH, β-endorphin samples, and measures of mood, compulsive exercise, and body image. Between group differences indicated that on-cycle AAS users had the highest β-endorphin levels, lowest cortisol levels, higher ACTH levels than controls. Conversely, off-cycle AAS users had the highest cortisol and ACTH levels, but the lowest β-endorphin levels. Exercise value was positively correlated with β-endorphin and symptoms of AAS dependence. The HPA response to AASs may explain why AASs are reinforcing in humans and exercise may play a key role in the development of AAS dependence. Copyright © 2014 Elsevier Ireland Ltd.

To investigate the effects of training sessions on circulating β-endorphin changes in sport horses before and after competition and to ascertain whether competition would affect this response. A total of 24 trained jumping horses were randomly assigned to one of two training groups: Group A (competing) and Group B (not competing). To determined plasma β-endorphin concentrations, two pre- and post-competition training weeks at aerobic workout and two competitive show jumping event days at anaerobic workout were measured before, 5 and 30 min after exercise. Exercise intensity is described using lactate concentrations and heart rate. The circuit design, intensity, and duration of training sessions were the same for both groups. In Group A, one-way analysis of variance for repeated measures (RM-ANOVA) showed significant effects of exercise on β-endorphin changes (F=14.41; prelease of β-endorphin and it may depend on the duration of the exercise program. Moreover, the responses during exercise in the course of post-competition training sessions seem to be significantly different from those the pre-competition training. These data show that the preliminary competitive stress induced additional significant changes of β-endorphin pattern. It would reflect the need of a long-lasting modulation of fatigue and pain perception related to the effect of an additional physical and mental effort for the consecutive competitive and training sessions.

The endogenous opioid system plays an important role in the behavioral effects of nicotine. Thus, μ-opioid receptor and the endogenous opioids derived from proenkephalin are involved in the central effects of nicotine. However, the role played by the different endogenous opioid peptides in the acute and chronic effects of nicotine remains to be fully established. Mice lacking β-endorphin were acutely injected with nicotine at different doses to evaluate locomotor, anxiogenic and antinociceptive responses. The rewarding properties of nicotine were evaluated by using the conditioned place-preference paradigm. Mice chronically treated with nicotine were acutely injected with mecamylamine to study the behavioral expression of nicotine withdrawal. Mice lacking β-endorphin exhibited a spontaneous hypoalgesia and hyperlocomotion and a reduction on the anxiogenic and rewarding effects induced by nicotine. Nicotine induced similar antinociception and hypolocomotion in both genotypes and no differences were found in the development of physical dependence. The dissociation between nicotine rewarding properties and physical dependence suggests a differential implication of β-endorphin in these addictive related responses. PMID:19376143

[History of acupuncture in Iran].

Iran is the neighbor of western China, and is a key transport junction on ancient Silk Road. The medical communication between China and Iran dates back to the 10th century, however, according to current evidences, it is indicated that acupuncture has not been introduced to Iran until the early 1970s. Unfortunately over the last 40 years, the acupuncture in Iran has not presented great development. The history of acupuncture development in Iran implies that geographical advantage and personnel exchanges are not essential to the international exchange of acupuncture, while language and cultural background may hinder the spread of acupuncture in foreign countries.

2012-01-01

Full Text Available Although the beneficial effects of acupuncture in asthma treatment have been well documented, little is known regarding the biological basis of this treatment. Changes in the lung proteome of acupuncture-treated rats with asthma onset were comparatively analyzed using a two-dimensional gel electrophoresis (2DE and mass-spectrometry- (MS- based proteomic approach. Acupuncture on specific acupuncture points appeared to improve respiratory function and reduce the total number of leukocytes and eosinophils in bronchoalveolar lavage fluid in OVA-induced asthma onset. Image analysis of 2DE gels revealed 32 differentially expressed acupuncture-specific protein spots in asthma onset; 30 of which were successfully identified as 28 unique proteins using LC-MS/MS. Bioinformatic analyses indicated that these altered proteins are most likely involved in inflammation-related biological functions, and the functional associations of these proteins result in an inflammation signaling pathway. Acupuncture regulates the pathway at different levels by regulating several key nodal proteins, including downregulating of proinflammatory proteins (e.g., S100A8, RAGE, and S100A11 and upregulating of anti-inflammatory proteins (e.g., CC10, ANXA5, and sRAGE. These deregulated inflammation-related proteins may mediate, at least in part, the antiasthmatic effect of acupuncture. Further functional investigation of these acupuncture-specific effector proteins could identify new drug candidates for the prophylaxis and treatment of asthma.

Acupuncture is widely used for pain treatment in patients with osteoarthritis or low back pain, but molecular mechanisms remain largely enigmatic. In the early phase of inflammation neutrophilic chemokines direct opioid-containing neutrophils in the inflamed tissue and stimulate opioid peptide release and antinociception. In this study the molecular pathway and neuroimmune connections in complete Freund's adjuvant (CFA)-induced hind paw inflammation and electroacupuncture for peripheral pain control were analyzed. Free moving Wistar rats with hind paw inflammation were treated twice with electroacupuncture at GB30 (Huan Tiao - gall bladder meridian) (day 0 and 1) and analyzed for mechanical and thermal nociceptive thresholds. The cytokine profiles as well as the expression of opioid peptides were quantified in the inflamed paw. Electroacupuncture elicited long-term antinociception blocked by local injection of anti-opioid peptide antibodies (beta-endorphin, met-enkephalin, dynorphin A). The treatment altered the cytokine profile towards an anti-inflammatory pattern but augmented interferon (IFN)-gamma and the chemokine CXCL10 (IP-10: interferon gamma-inducible protein) protein and mRNA expression with concomitant increased numbers of opioid peptide-containing CXCR3+ macrophages. In rats with CFA hind paw inflammation without acupuncture repeated injection of CXCL10 triggered opioid-mediated antinociception and increase opioid-containing macrophages. Conversely, neutralization of CXCL10 time-dependently decreased electroacupuncture-induced antinociception and the number of infiltrating opioid peptide-expressing CXCR3+ macrophages. In summary, we describe a novel function of the chemokine CXCL10 - as a regulator for an increase of opioid-containing macrophages and antinociceptive mediator in inflammatory pain and as a key chemokine regulated by electroacupuncture.

Modell, J H; Lee, P K; Bingham, H G; Greer, D M; Habal, M B

1976-01-01

Forty-two patients who were to undergo plastic surgical procedures were asked whether they would accept acupuncture as a substitute for local anesthesia. Eight patients agreed to acupuncture; one of these had 2 operative procedures with acupuncture. Five of the 9 procedures were successful; the remaining 4 required conversion to local anesthesia. After interviewing the patients, we felt that the success of "acupuncture anesthesia" was largely dependent on patient motivation, and that a patient may experience pain during surgical procedures without any change in facial expression or vital signs. We concluded that "acupuncture anesthesia" is of little value in our patient population at present. Its results are unpredictable; therefore, we anticipate that patient acceptance will be small.

[Comments on the definition of "acupuncture science"].

2017-12-12

The experts in China believe that the substance of "dry needling" is in the category of acupuncture therapy for the treatment by needle inserting the human body. But, its recognition has not been implied from the definition of "acupuncture science". Since 1970 s, the different definitions of it are closely related to TCM theories, due to which, it has been limited. This flaw restricts the development of acupuncture theory, narrows the connotation of acupuncture science and goes against the communication of traditional Chinese acupuncture theory. No matter regarding the theory or technique, the acupuncture therapy nowadays changes greatly in its connotation. Rather than guided by TCM theories, acupuncture therapy mainly includes the nerve trunk stimulation theory, the cerebral function orientation therapy, biological holographic therapy, fascia stimulation therapy and trigger therapy, etc. Expect that the medical devices used in these therapies are same as the traditional acupuncture, these methods cannot be regarded in the category of acupuncture science when the current definition of it is considered. Hence, the writer is trying to define "acupuncture science" as: acupuncture science refers to the science for the methodology and mechanism of therapeutic devices, e.g. acupuncture therapy and moxibustion therapy, for the prevention and treatment of disease by stimulating the body, and its theory includes but not limits in traditional Chinese medical theory.

Restless legs syndrome (RLS) is a common movement disorder for which patients may seek treatment with acupuncture. However, the benefits of acupuncture in the treatment of RLS are unclear and have not been evaluated in a systematic review until now. To evaluate the efficacy and safety of acupuncture therapy in patients with RLS. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2007), MEDLINE (January 1950 to February 2007), EMBASE (January 1980 to 2007 Week 8), Chinese Biomedical Database (CBM) (1978 to February 2007), China National Knowledge Infrastructure (CNKI) (1979 to February 2007), VIP Database (1989 to February 2007), Japana Centra Revuo Medicina (1983 to 2007) and Korean Medical Database (1986 to 2007). Four Chinese journals, relevant academic conference proceedings and reference lists of articles were handsearched. Randomized controlled trials and quasi-randomized trials comparing acupuncture with no intervention, placebo acupuncture, sham acupuncture, pharmacological treatments, or other non-acupuncture interventions for primary RLS were included. Trials comparing acupuncture plus non-acupuncture treatment with the same non-acupuncture treatment were also included. Trials that only compared different forms of acupuncture or different acupoints were excluded. Two authors independently identified potential articles, assessed methodological quality and extracted data. Relative risk (RR) was used for binary outcomes and weighted mean difference for continuous variables. Results were combined only in the absence of clinical heterogeneity. Fourteen potentially relevant trials were identified initially, but twelve of them did not meet the selection criteria and were excluded. Only two trials with 170 patients met the inclusion criteria. No data could be combined due to clinical heterogeneity between trials. Both trials had methodological and/or reporting shortcomings. No significant difference was detected

Objective This study tested a pathway whereby acupuncturists’ communication of optimism for treatment effectiveness would enhance patients’ satisfaction during treatment, which in turn would contribute to better pain and function outcomes for patients with osteoarthritis of the knee. Methods Secondary analysis from a 2 arm (real vs. sham acupuncture, high vs. neutral expectations) RCT. 311 patients with knee osteoarthritis received acupuncture over 10–12 sessions. Coders rated the degree to which acupuncturists communicated optimism for the treatment’s effectiveness. Satisfaction with acupuncture was assessed 4 weeks into treatment. Pain and function were assessed 6 weeks following treatment. Results Patients experiencing better outcomes were more satisfied with acupuncture during treatment, were younger, and had better baseline pain and function scores. Satisfaction during treatment was greater when patients interacted with more optimistic clinicians and had higher pretreatment expectations for acupuncture efficacy. Conclusion Acupuncturists’ communication of optimism about treatment effectiveness contributed to pain and function outcomes indirectly through its effect on satisfaction during treatment. Future research should model pathways through which clinician-patient communication affects mediating variables that in turn lead to improved health outcomes. Practical Implications While clinicians should not mislead patients, communicating hope and optimism for treatment effectiveness has therapeutic value for patients. PMID:22857778

A computer controlled automated setup has been designed to investigate the body acupuncture points (bio-active points) by using a probes matrix which exerts a uniform pressure on the body. 16 probes matrix was placed in a 15 : 15 mm/sup 2/ dielectric substrate with 5 mm inter probe distance, compatible with the average diameter of the points. These probes have been designed to facilitate a semiconductor injection laser for probing of the points along with optical and/or electric signal. The bioactive points were identified by evaluating the impedance between each probe and a hand held electrode through a micro-controlled scan. This also allowed the selection of an appropriate signal - DC, AC or tidal waveform, for the electric treatment of bioactive points. It has been found that body impedance decreases with the increase of measuring voltage. Moreover, for current-voltage characteristics a nonlinearity coefficient in the range 2-3 was also observed. The study revealed that at low applied voltages 0.l V, the impedance depends on the polarity of the applied signal. Furthermore, body impedance decreases nonlinearly by increasing the probe's pressure on the skin, which may be attributed to piezo resistive effect. By using the AC and Dc measurements an appropriate body equivalent circuit is proposed in this investigation. (author)

Point specificity in acupuncture

Directory of Open Access Journals (Sweden)

Choi Emma M

2012-02-01

Full Text Available Abstract The existence of point specificity in acupuncture is controversial, because many acupuncture studies using this principle to select control points have found that sham acupoints have similar effects to those of verum acupoints. Furthermore, the results of pain-related studies based on visual analogue scales have not supported the concept of point specificity. In contrast, hemodynamic, functional magnetic resonance imaging and neurophysiological studies evaluating the responses to stimulation of multiple points on the body surface have shown that point-specific actions are present. This review article focuses on clinical and laboratory studies supporting the existence of point specificity in acupuncture and also addresses studies that do not support this concept. Further research is needed to elucidate the point-specific actions of acupuncture.

2017-01-01

Abstract Background: This systematic review aimed at summarizing and evaluating the evidence from randomized controlled trials (RCTs) using acupuncture to treat polycystic ovarian syndrome (PCOS), specifically focusing on ovulation rate, menstrual rate, and related hormones. Methods: Fifteen databases were searched electronically through February 2016. Our review included RCTs of women with PCOS; these RCTs compared acupuncture with sham acupuncture, medication, or no treatment. Two reviewers independently extracted data. Data were pooled and expressed as mean differences (MDs) for continuous outcomes and risk ratios for dichotomous outcomes, with 95% confidence intervals (CIs) using a random-effects model. Results: We found a low level of evidence that acupuncture is more likely to improve ovulation rate (MD 0.35, 95% CI: 0.14–0.56) and menstruation rate (MD 0.50, 95% CI: 0.32–0.68) compared with no acupuncture. We found statistically significant pooled benefits of acupuncture treatment as an adjunct to medication in luteinizing hormone (LH), LH/follicular stimulating hormone (FSH) ratio, testosterone, fasting insulin, and pregnancy rates, but the level of evidence was low/very low. Conclusion: There is limited evidence to judge the efficacy and safety of acupuncture on key reproductive outcomes in women with PCOS. Large-scale, long-term RCTs with rigorous methodological input are needed. PMID:28591042

ABSTRACT The exploration course on production standard of acupuncture needle by Chengjiang acupuncture school is reviewed in this paper. After new China was established, acupuncture needle standard was unified by Mr. CHENG Dan-an, which guided Suzhou Hua Erfang (predecessor of Suzhou Medical Supplies Factory) to make the quality standards and testing methods of acupuncture needle and improved the production process to make the modern acupuncture needle. Based on this, Suzhou Medical Supplies Factory followed the time development pace, ac tively introduced new technology, carried out technological innovation, and constantly improved the level of production technology, as a result, it gradually developed into one of the world's largest acupuncture needle production suppliers. Meanwhile, after establishing China's first national standard on acupuncture needle (GB 2024-1980), the Suzhou Medical Supplies Factory took the lead to draft "ISO) 17218:2014 the disposable use asepsis acupuncture needle", which was officially published as an international standard. The Suzhou Medical Supplies Factory developed from a manual workshop to an international standard maker.

It is well known that acupuncture has pain-relieving effects, but the contribution of specific and especially non-specific factors to acupuncture analgesia is less clear. One hundred and one patients who developed pain ≥ 3 on a visual analog scale (VAS, 0-10) following third molar surgery were randomized to receive active acupuncture, placebo acupuncture, or no treatment for 30 min with acupuncture needles with potential for double-blinding. Patients’ perception of the treatment (active or placebo), and expected pain levels (VAS) were assessed prior to and halfway through the treatment. Looking at actual treatment allocation, there was no specific effect of active acupuncture (P = 0.240), but a large and significant non-specific effect of placebo acupuncture (P acupuncture (P acupuncture had significantly lower pain levels than those who believed they received placebo acupuncture. Expected pain levels accounted for significant and progressively larger amounts of the variance in pain ratings following both active and placebo acupuncture (up to 69.8%), This is the first study to show that under optimized blinding conditions non-specific factors such as patients’ perception of and expectations toward treatment are central to the efficacy of acupuncture analgesia and that these factors may contribute to self-reinforcing effects in acupuncture treatment To obtain an effect of acupuncture in clinical practice it may, therefore, be important to incorporate and optimize these factors.

Full Text Available The aim of this paper was to provide reliable evidence by performing a systematic review and meta-analysis for evaluating the role of acupuncture in assisted reproductive technology. All randomized controlled trials that evaluated the effects of acupuncture, including manual, electrical, and laser acupuncture (LA techniques, on the clinical pregnancy rate (CPR and live birth rate (LBR of in vitro fertilization (IVF or artificial insemination were included. The controlled groups consisted of no acupuncture and sham acupuncture groups. The sham acupuncture included sham acupuncture at acupoints, sham acupuncture at non- or inappropriate points, sham LA, and adhesive tapes. Twenty-three trials (a total of 5598 participants were included in this paper. The pooled CPR from all acupuncture groups was significantly higher than that from all controlled groups, whereas the LBR was not significantly different between the two groups. However, the results were quite distinct when the type of control and/or different acupuncture times were examined in a sensitivity analysis. The results mainly indicate that acupuncture, especially around the time of the controlled ovarian hyperstimulation, improves pregnancy outcomes in women undergoing IVF. More positive effects from acupuncture in IVF can be expected if a more individualized acupuncture programs are used.

The aims of this study was to elucidate the effect of balanced physical exercise on physical fitness, endorphin levels, and malondialdehyde (MDA levels. Methods: This study was a true experimental with pretest-posttest control group design using 24 students of IKIP PGRI Denpasar. Selected samples divided into two groups: the control group given conventional physical training (P0 and the treatment group given balanced physical training (P1. Physical fitness tests was performed using Cooper method and blood sampling was done to evaluate the level of endorphins and MDA before (pre test and after (post test treatment of 8 weeks. The data of endorphin and MDA levels were analyzed using independent T test. Whereas, the physical fitness was analyzed using Mann-Whitney U test. Results: Physical fitness of the group given a balanced physical training was significantly higher compare to the group given a conventional physical training (p < 0.05. Balanced physical training was proven to enhance physical fitness as measured by the Cooper method better than conventional physical training. In contrast, the levels of endorphins of the balanced physical training group did not different with the conventional physical training group (p > 0.05. Levels of MDA of balanced physical training group also did not different with the conventional physical training group (p > 0.05. Conclusions: balanced physical training can maintain physical fitness of people and improve the health and quality of life.

The beginning of TCM acupuncture in New Zealand dates back to the middle of 19th century. After self-improvement for more than 100 years, TCM acupuncture has gained a considerable development. From the perspective of history and current situation, the development of acupuncture in New Zealand was elaborated in this article; in addition, the sustainable development of acupuncture was discussed from the perspective of education and training. In New Zealand, the TCM acupuncture and dry needling have played a dominant role in acupuncture treatments, which are practiced by TCM practitioners and physical therapists. The TCM acupuncture is widely applied in department of internal medicine, surgery, gynecology, and pediatrics, etc., while the dry needling is li-mited for traumatology and pain disorder. Therefore, including TCM acupuncture into the public medical and educational system in New Zealand should be an essential policy of Ministry of Health to provide welfare for the people.

In the present paper, the authors make a bibliometrics study on clinical indications of acupuncture therapy based on the published foreign articles about acupuncture clinical trials collected from PubMed database and Excerpta Medica database (EMbase). In 1996, 64 acupuncture indications were declared by WHO in Milan conference. But in recent 15 years, clinical trials have been conducted extensively in the foreign countries. Till now, 77 new indications for acupuncture therapy have been found in the foreign journals. The authors recommended that 29 indications (knee osteoarthritis, critique age problems, muscular fasciae ache, anxiety, etc.) should be added to the first class, 4 indications (irritable bowel syndrome, malposition, backache, simple obesity) should be upgraded from the second class to the first class, and the other 3 indications (childbirth pain, male and female barren) should be upgraded from the third class to the first class due to their application frequency in clinical trials. Increase of clinical indications reflects extensive application of acupuncture therapy and may help providing a better service for people's health.

Acupuncture was first used in China, probable about 2000 years ago. When acupuncture first arrived in the West in the 17th century, the principles which the Chinese had used to explain its actions were at variance with current scientific knowledge of the body's structure and function. This led to the rejection of acupuncture by the medical profession in the UK, although individual practitioners adopted it with enthusiasm, usually needling the point of maximal tenderness to treat musculoskeletal pain. Acupuncture was more generally accepted in France and Germany, where the pioneering British physician Felix Mann encountered it in the 1950s. He then taught acupuncture to other medical practitioners and organised regular meetings in London, from which the British Medical Acupuncture Society, BMAS, emerged in 1980. The tradition of biannual scientific meetings has continued since then. The Society has many connections with prominent acupuncturists internationally and is a founder member of the International Council of Medical Acupuncture and Related Techniques (ICMART), and has hosted two world congresses. The Society was involved in standardisation of the meridian nomenclature published in 1990. The Society's scientific journal, Acupuncture in Medicine, was founded in 1981 and has gained international recognition, being indexed on several databases. The Society has established regular teaching courses at different levels, which lead to professional qualifications of Certificate and Diploma. The membership is now open to different health professionals, has grown steadily and now stands at nearly 2500. The Society is administered from offices in Cheshire and London. Many individual members have contributed to the Society's characteristic Western 'medical' approach to acupuncture in which needling is seen as a form of neuromuscular stimulation that owes little to traditional meridians or points. The Society has shown a particular interest in acupuncture for myofascial

Full Text Available Abstract Background Electroacupuncture (EA can produce analgesia by increasing the β-endorphin level and activation of peripheral μ-opioid receptors in inflamed tissues. Endogenous cannabinoids and peripheral cannabinoid CB2 receptors (CB2Rs are also involved in the antinociceptive effect of EA on inflammatory pain. However, little is known about how peripheral CB2Rs interact with the endogenous opioid system at the inflammatory site and how this interaction contributes to the antinociceptive effect of EA on inflammatory pain. In this study, we determined the role of peripheral CB2Rs in the effects of EA on the expression of β-endorphin in inflamed skin tissues and inflammatory pain. Results Inflammatory pain was induced by injection of complete Freund's adjuvant into the left hindpaw of rats. Thermal hyperalgesia was tested with a radiant heat stimulus, and mechanical allodynia was quantified using von Frey filaments. The mRNA level of POMC and protein level of β-endorphin were quantified by real-time PCR and Western blotting, respectively. The β-endorphin-containing keratinocytes and immune cells in the inflamed skin tissues were detected by double-immunofluorescence labeling. The CB2R agonist AM1241 or EA significantly reduced thermal hyperalgesia and mechanical allodynia, whereas the selective μ-opioid receptor antagonist β-funaltrexamine significantly attenuated the antinociceptive effect produced by them. AM1241 or EA significantly increased the mRNA level of POMC and the protein level of β-endorphin in inflamed skin tissues, and these effects were significantly attenuated by pretreatment with the CB2R antagonist AM630. AM1241 or EA also significantly increased the percentage of β-endorphin-immunoreactive keratinocytes, macrophages, and T-lymphocytes in inflamed skin tissues, and these effects were blocked by AM630. Conclusions EA and CB2R stimulation reduce inflammatory pain through activation of μ-opioid receptors. EA increases

Objective Acupuncture has been studied as an adjunct for addictions treatment. Because many hospitals, outpatient clinics, and facilities are integrating acupuncture treatment, it is important that psychiatrists remain informed about this treatment. This manuscript describes the National Acupuncture Detoxification Association (NADA) protocol and its inclusion as part of the curriculum for psychiatry addictions fellows. Methods Psychiatry and psychology fellows completed the NADA training (N = 20) and reported on their satisfaction with the training. Results Overall, participants stated that they found the training beneficial and many were integrating acupuncture within their current practice. Conclusions Results support the acceptability of acupuncture training among psychiatry fellows in this program. PMID:26048457

Full Text Available The objective of this study was to assess the efficacy and safety of electroacupuncture in 138 patients with earthquake-caused PTSD using Randomized Controlled Trials (RCTs. 138 cases enrolled were randomly assigned to an electro-acupuncture group and a paroxetine group. The electro-acupuncture group was treated by scalp electro-acupuncture on Baihui (GV 20, Sishencong (EX-HN 1, Shenting (GV 24, and Fengchi (GB 20, and the paroxetine group was treated with simple oral administration of paroxetine. The efficacy and safety of the electro-acupuncture on treatment of 69 PTSD patients were evaluated using Clinician-Administered PTSD Scale (CAPS, Hamilton Depression Scale (HAMD, Hamilton Anxiety Scale (HAMA, and Treatment Emergent Symptom Scale (TESS according to clinical data. The total scores of CAPS, HAMD, and HAMA in the two groups after treatment showed significant efficacy compared to those before treatment. The comparison of reduction in the scores of CAPS, HAMD, and HAMA between the two groups suggested that the efficacy in the treated group was better than that in the paroxetine group. The present study suggested that the electro-acupuncture and paroxetine groups have significant changes in test PTSD, but the electro-acupuncture 2 group was more significant.

The aim of this study was to investigate the effects of acupuncture on peripheral lymphocyte subpopulations and cerebral catecholamines. In order to examine the effects of acupuncture, two experiments were performed. Experiment 1: Eighteen female mice (strain; C57BL/6) at the age of 7 weeks were divided three groups, (a) sham operated (control; n=6), (b) ovariectomized (OVX; n=6), and (c) ovariectomized and stimulated by subcutaneous needles on acupuncture point, Shenshu (BL23) at the both sides of the back for 20 days (OVX+Acu; n=6). These animals were sacrificed at 20 days after needle insertion, and the splenic lymphoid cells were examined by two-color flow cytometry, using monoclonal antibodies (mAb) to the cell surface antigens, CD3, CD4, CD8a and NK1.1 (CD56). In the ovariectomized (OVX) group, the peripheral CD4/CD8 ratio was significantly increased and the ratio of natural killer (NK) cells (CD3-NK1.1+; CD3 negative, NK1.1 positive) to T lymphocytes was decreased compared to the sham control group. In the ovariectomized with needle insertion (OVX+Acu) group, the CD4/CD8 ratio was reduced, but the NK cells ratio was not changed compared to the OVX group. Experiment 2: To investigate the acute effects of subcutaneous needle insertion, male C57BL/6 mice (7 weeks old) were used (n=6, each group). The acupuncture points Shen-shu (BL23) on the backs of the male mice were also stimulated by subcutaneous needles for 3 and 7 days. As a result, the CD4/CD8 ratio was significantly decreased at day 3 and day 7, compared to the control group. On the other hand the NK cells ratio and activated T-cells were increased at day 7. The mitogenic activities in the splenic lymphocytes were also increased by acupuncture stimulation at day 3. Catecholamine contents in the hippocampus were measured by high performance liquid chromatography with the electro-chemical detector (ECD-HPLC) method. No significant change was observed in either dopamine contents or norepinephrine; however

To determine whether acupuncture use, sociodemographic characteristics, and existing health conditions differ between acupuncture-preferred consumers (i.e., those who deem acupuncture to be one of the three most important complementary and alternative medicine [CAM] modalities used) and non-acupuncture-preferred consumers who used acupuncture in the past 12 months This is a secondary analysis of the National Health Interview Survey Sample Adult File and Adult Alternative Medicine datasets collected by the Centers for Disease Control and Prevention during 2012. The sample was drawn from the noninstitutionalized civilian population of the United States. The datasets yielded 34,525 respondents aged 18 years and older. Measures included in the analysis were acupuncture use in the past 12 months, sociodemographic characteristics, and existing health conditions. Analyses were performed by using Stata software, version 9.0 (Stata Corp., College Station, TX). Of the 10,158 adults who responded to the question regarding the "three most important" CAM modalities used, 572 (5.6%) had used acupuncture in the past 12 months. Of these, 456 (79.7%) chose acupuncture as one of the top three CAM modalities most important to their health. Acupuncture-preferred consumers reported significantly more visits to acupuncturists (7.46 versus 3.99 visits; p < 0.001), as well as higher out-of-pocket costs ($342.8 versus $246.4; p < 0.001), compared with non-acupuncture-preferred consumers. The logistic regression model revealed that with every additional CAM modality used, the likelihood of deeming acupuncture as one of the three CAM modalities most important to one's health decreased by 39% (odds ratio, 0.61; 95% confidence interval, 0.52-0.71; p < 0.001). Health conditions were not statistically significant predictors. A consumer's preference for acupuncture appeared not to be driven by health conditions but rather was related to sociodemographic factors. This suggests that

Acupuncture is one of the branches of Chinese Traditional Medicine dating back almost 5 000 years. The expansion of China's trade and business relations with other Asian countries brought about the spreading of acupuncture in 7th Century. Nowadays, acupuncture is an interdisciplinary clinical field of Medicine dealing with treatment, diagnostics and prevention of mainly functional disorders, algic, allergic and addictive conditions of various etiology, localization and intensity. It draws from the millennia of experience of Oriental Medicine as well as contemporary knowledge of morphology, physiology and neurophysiology. The acupuncture method is based on influencing the body functions in a precise way by controlled irritation of particular active meridian points using special needles, heat (moxibustion), pressure (acupressure), underpressure (cupping), electricity (electroacupuncture), light (laser therapy), ultrasound (sonopuncture), static or pulsating electromagnetic field (magnetic therapy) and solutions (pharmacopuncture).The use of acupuncture as a method of pain relief in Modern Western Medicine is based on a wide range of clinical trials, and there is no doubt that it has significant effect in the treatment of acute and chronic pain classification. The introduction of gate-control theory and endogenous opioids facilitated the recognition of acupuncture in pain treatment.

Meta-analyses and reviews of acupuncture and related techniques for postoperative nausea and vomiting (POVN and postoperative vomiting (POV show promising results while many clinicians remain skeptical of the value of acupuncture. Given the interest in finding safe non-pharmacological approaches toward postoperative care, this body of knowledge needs to be considered. This review critically appraises and summarizes the research on acupuncture and acupressure in ambulatory anesthesia during the last 15 years.Methods: Articles were identified through searches of Medline, PubMed, and Embase using the search terms “acupuncture” or “acupuncture therapy” in combination with “ambulatory anesthesia” or “ambulatory surgery” or “day surgery” or “postoperative”. A corresponding search was done using “acupressure” and “wristbands”. The searches generated a total of 104, 118, and 122 references, respectively.Results: Sixteen studies were included; eight studies reported on acupuncture and eight on acupressure. Nine studies found acupuncture or acupressure effective on primary endpoints including postoperative nausea and vomiting, postoperative pain, sore throat, and emergence agitation. Four studies found acupuncture had a similar effect to antiemetic medication.Conclusion: Overall, the studies were of fairly good quality. A large proportion of the reviewed papers highlights an effect of acupuncture or acupressure on postoperative morbidities in an ambulatory setting

Background Hordeolum is an acute, purulent inflammation of the eyelid margin usually caused by obstructed orifices of the sebaceous glands of the eyelid. The condition, which affects sebaceous glands internally or externally, is common. When the meibomian gland in the tarsal plate is affected, internal hordeolum occurs, while when the glands of Zeis or Moll associated with eyelash follicles are affected, external hordeolum, or stye occurs. The onset of hordeolum is usually self limited, and may resolve in about a week with spontaneous drainage of the abscess. When the condition is severe, it can spread to adjacent glands and tissues. Recurrences are very common. As long as an internal hordeolum remains unresolved, it can develop into a chalazion or generalized eyelid cellulitis. Acupuncture is a traditional Chinese medical therapy aimed to treat disease by using fine needles to stimulate specific points on the body. However, it is unclear if acupuncture is an effective and safe treatment for acute hordeolum. Objectives The objective of this review was to investigate the effectiveness and safety of acupuncture to treat acute hordeolum compared with no treatment, sham acupuncture, or other active treatment. We also compared the effectiveness and safety of acupuncture plus another treatment with that treatment alone. Search methods We searched CENTRAL, Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, Embase, PubMed, Latin American and Caribbean Health Sciences Literature Database (LILACS), three major Chinese databases, as well as clinical trial registers all through 7 June 2016. We reviewed the reference lists from potentially eligible studies to identify additional randomised clinical trials (RCTs). Selection criteria We included RCTs of people diagnosed with acute internal or external hordeola. We included RCTs comparing acupuncture with sham acupuncture or no treatment, other active treatments, or

Beta-lapachone (beta-Lp) derived from the Lapacho tree is a potentially novel anticancer agent currently under clinical trials. Previous studies suggested that redox activation of beta-Lp catalyzed by NAD(P)H:quinone oxidoreductase 1 (NQO1) accounted for its killing of cancer cells. However, the exact mechanisms of this effect remain largely unknown. Using chemiluminescence and electron paramagnetic resonance (EPR) spin-trapping techniques, this study for the first time demonstrated the real-time formation of ROS in the redox activation of beta-lapachone from cancer cells mediated by mitochondria and NQO1 in melanoma B16–F10 and hepatocellular carcinoma HepG2 cancer cells. ES936, a highly selective NQO1 inhibitor, and rotenone, a selective inhibitor of mitochondrial electron transport chain (METC) complex I were found to significantly block beta-Lp meditated redox activation in B16–F10 cells. In HepG2 cells ES936 inhibited beta-Lp-mediated oxygen radical formation by ∼ 80% while rotenone exerted no significant effect. These results revealed the differential contribution of METC and NQO1 to beta-lapachone-induced ROS formation and cancer cell killing. In melanoma B16–F10 cells that do not express high NQO1 activity, both NOQ1 and METC play a critical role in beta-Lp redox activation. In contrast, in hepatocellular carcinoma HepG2 cells expressing extremely high NQO1 activity, redox activation of beta-Lp is primarily mediated by NQO1 (METC plays a minor role). These findings will contribute to our understanding of how cancer cells are selectively killed by beta-lapachone and increase our ability to devise strategies to enhance the anticancer efficacy of this potentially novel drug while minimizing its possible adverse effects on normal cells. - Highlights: • Both isolated mitochondria and purified NQO1 are able to generate ROS by beta-Lp. • The differential roles of mitochondria and NQO1 in mediating redox activation of beta-Lp • In cancer cells with

Acupuncture has been shown to reduce pain, and acupuncture-induced sensation may be important for this analgesia. In addition, cognitive coping strategies can influence sensory perception. However, the role of coping strategy on acupuncture modulation of pain and sensory thresholds, and the association between acupuncture sensation and these modulatory effects, is currently unknown. Electroacupuncture (EA) was applied at acupoints ST36 and GB39 of 61 healthy adults. Different coping conditions were experimentally designed to form an active coping strategy group (AC group), who thought they could control EA stimulation intensity, and a passive coping strategy group (PC group), who did not think they had such control. Importantly, neither group was actually able to control EA stimulus intensity. Quantitative sensory testing was performed before and after EA, and consisted of vibration (VDT), mechanical (MDT), warm (WDT), and cold (CDT) detection thresholds, and pressure (PPT), mechanical (MPT), heat (HPT) and cold (CPT) pain thresholds. Autonomic measures (e.g. skin conductance response, SCR) were also acquired to quantify physiological response to EA under different coping conditions. Subjects also reported the intensity of any acupuncture-induced sensations. Coping strategy was induced with successful blinding in 58% of AC subjects. Compared to PC, AC showed greater SCR to EA. Under AC, EA reduced PPT and CPT. In the AC group, improved pain and sensory thresholds were correlated with acupuncture sensation (VDTchange vs. MI: r=0.58, CDTchange vs. tingling: r=0.53, CPTchange vs. tingling; r=0.55, CPTchange vs. dull; r=0.55). However, in the PC group, improved sensory thresholds were negatively correlated with acupuncture sensation (CDTchange vs. intensity sensitization: r=-0.52, WDTchange vs. fullness: r=-0.57). Our novel approach was able to successfully induce AC and PC strategies to EA stimulation. The interaction between psychological coping strategy and

In the present study we tested the hypothesis that repeated EA treatments modulates sympathetic nerve activity in rats with PCO. This was done by analysing endothelin-1 (ET-1, a potent vasoconstrictor involved in ovarian functions, as well as NGF and NGF mRNA expression involved in the pathophysiological process underlying steroid-induced PCO. The main result in the present study was that concentrations of ET-1 in the ovaries were significantly lower in the PCO group receiving EA compared with the healthy control group (p p p p

Simulated annealing model of acupuncture

Shang, Charles; Szu, Harold

2015-05-01

The growth control singularity model suggests that acupuncture points (acupoints) originate from organizers in embryogenesis. Organizers are singular points in growth control. Acupuncture can cause perturbation of a system with effects similar to simulated annealing. In clinical trial, the goal of a treatment is to relieve certain disorder which corresponds to reaching certain local optimum in simulated annealing. The self-organizing effect of the system is limited and related to the person's general health and age. Perturbation at acupoints can lead a stronger local excitation (analogous to higher annealing temperature) compared to perturbation at non-singular points (placebo control points). Such difference diminishes as the number of perturbed points increases due to the wider distribution of the limited self-organizing activity. This model explains the following facts from systematic reviews of acupuncture trials: 1. Properly chosen single acupoint treatment for certain disorder can lead to highly repeatable efficacy above placebo 2. When multiple acupoints are used, the result can be highly repeatable if the patients are relatively healthy and young but are usually mixed if the patients are old, frail and have multiple disorders at the same time as the number of local optima or comorbidities increases. 3. As number of acupoints used increases, the efficacy difference between sham and real acupuncture often diminishes. It predicted that the efficacy of acupuncture is negatively correlated to the disease chronicity, severity and patient's age. This is the first biological - physical model of acupuncture which can predict and guide clinical acupuncture research.

Full Text Available Oncology acupuncture has become a new and promising field of research because more and more cancer patients have sought non-pharmacological alternatives for symptom management. While different mechanisms have been proposed to explain its efficacy, including theories of the neural system, endocrine cytokine or immunological regulation, its eventual role has become that of alleviating the side effects induced by chemotherapy or radiotherapy. In this paper, we have reviewed the related articles focusing on acupuncture mechanisms and applications in cancer care to provide a quick sketch of acupuncture in cancer care. A detailed search was performed to identify the randomized controlled trials (RCTs and systematic reviews on acupuncture in oncology, using PUBMED and Cochrane. The search terms included: Acupuncture, acupressure, and cancer. Additional terms were used to target specific symptoms (i.e., breast cancer, hot flash, xerostomia, nausea, vomiting, cancer pain, insomnia, fatigue. Two authors independently extracted data for analysis and review. Ultimately, 25 articles underwent full-text review. Recent trials made efforts in studying (a hot flashes in breast cancer, (b xerostomia induced by radiotherapy in head and neck cancer, (c nausea and vomiting post-chemotherapy, (d cancer pain, and (e fatigue and insomnia in cancer patients. Controversial results for acupuncture application in cancer care appeared in different categories, but a trend emerged that acupuncture can palliate cancer-related symptoms. The research to date certainly offers us a valid complementary therapy in treating cancer-related symptoms. Meanwhile, practical strategies with safe measures for enhancing the efficacy are needed in further interventions, as well as continuing research with a validated methodology.

Most neuropeptides are incapable of entering the brain from blood owing to the presence of unique anatomical structures in the brain capillary wall, which makes up the blood-brain barrier (BBB). Such neuropeptides could be introduced into the bloodstream by intranasal insufflation and, thus, could have powerful medicinal properties (e.g., Beta-endorphin for the treatment of pain, vasopressin analogues for treatment of memory, ACTH analogues for treatment of post-traumatic epilepsy), should these peptides be capable of traversing the BBB. One such strategy for peptide delivery through the BBB is the development of chimeric peptides, which is the basis of the present contract. The production of chimeric peptides involves the covalent coupling of a nontransportable peptide (e.g., Beta-endorphin, vasopressin) to a transportable vector peptide (e.g., insulin, transferrin, cationized albumin, histone). The transportable peptide is capable of penetrating the BBB via receptor-mediated or absorptive-mediated transcytosis. Therefore, the introduction of chimeric peptides allows the nontransportable peptide to traverse the BBB via a physiologic piggy back mechanism.

Do Endorphins represent the biochemical basis of inheritance of mental information?

Directory of Open Access Journals (Sweden)

Machado Dias, Álvaro

2009-12-01

Full Text Available In a recent article (06/2009, Halabe Bucay presents the hypothesis that endorphins can be a core element in the transmission of mental information produced during life to the next generation. This paper argues that Bucay’s model is based on four essential axioms, which are subject to debate.The aim of this paper is to discuss these specific axioms and evaluate the feasibility of the hypothesis. The specific axioms are: 1. “Endorphins act directly on different sperm function which impliestheir influence on the genetic expressivity of the same”; 2. Exogenous opioids affect genes and this could be a means through which acquired information could be transmitted to the next generationsunder the influence of endogenous opioids; 3. “Mental information produced through life” could be transmitted; 4. Endorphins are specifically related to the presumed phenomenon, thus justifying theepistemological frame. The four axioms are contested by most (if not all studies addressing these specific issues which leads us to conclude that the hypothesis cannot be held. At the same time,the hypothesis presents a timely opportunity to discuss the role of neuropeptides on behavior and their possible role in the constitution of the brain, in regard to which we add that it is possible thatendorphin levels within fetal and neonate milieus are associated with epigenic processes (e.g., methylations and produce lifelong effects —although we do not develop this idea further, since it wouldrequire a totally different focus, based on completely different axioms—.

The study aimed to investigate the analgesic effect of a combination of intravenous flurbiprofen axetil and opioids, and evaluate the relationship between refractory pain relief and plasma β-endorphin levels in cancer patients. A total of 120 cancer patients was randomly divided into two groups, 60 patients took orally morphine sulfate sustained-release tablets in group A, and another 60 patients receiving the combination treatment of intravenous flurbiprofen axetil and opioid drugs in group B. After 7 days, pain relief, quality of life improvement and side effects were evaluated. Furthermore, plasma β-endorphin levels were measured by radioimmunoassay. With the combination treatment of intravenous intravenous flurbiprofen axetil and opioids, the total effective rate of pain relief rose to 91.4%, as compared to 82.1% when morphine sulfate sustained-release tablet was used alone. Compared with that of group A, the analgesic effect increased in group B (p=0.031). Moreover, satisfactory pain relief was associated with a significant increase in plasma β-endorphin levels. After the treatment, plasma β-endorphin level in group B was 62.4±13.5 pg/ml, which was higher than that in group A (45.8±11.2 pg/ml) (pflurbiprofen axetil and opioids can enhance the analgesic effect of opioid drugs by increasing plasma β-endorphin levels, which would offer a selected and reliable strategy for refractory cancer pain treatment.

Transforming growth factor beta (TGF-beta) has been considered as a candidate for gene therapy of orthopedic diseases. The possible application of cell-mediated TGF-beta gene therapy as a new treatment regimen for degenerative arthritis was investigated. In this study, fibroblasts expressing active TGF-beta 1 were injected into the knee joints of rabbits with artificially made cartilage defects to evaluate the feasibility of this therapy for orthopedic diseases. Two to 3 weeks after the injection there was evidence of cartilage regeneration, and at 4 to 6 weeks the cartilage defect was completely filled with newly grown hyaline cartilage. Histological analyses of the regenerated cartilage suggested that it was well integrated with the adjacent normal cartilage at the sides of the defect and that the newly formed tissue was indeed hyaline cartilage. Our findings suggest that cell-mediated TGF-beta 1 gene therapy may be a novel treatment for orthopedic diseases in which hyaline cartilage damage has occurred.

After Chiso brought acupuncture to Japan from Wu (China) in the sixth century, it has progressed in unique ways within the various historical milieus of the past 1500 years. Ishitsu-rei, the first medical law of Japan established in 701, explains the medical system of acupuncture in detail showing that acupuncture was being administered under the authorization of the national government. For the next 1200 years, acupuncture continued to be an important facet of public health in Japan. From the Azuchimomoyama through the Edo period, the knowledge exchange with China became active and people who studied in China developed new styles and techniques of acupuncture treatment and organized their own private schools or ryu-ha in Japan. In 1635, when the Edo government decided to close the country, Japan cut-off exchange with foreign countries for over 200 years. The national isolation caused some development that was unique to Japan. During that time, acupuncture filtered into people's everyday lives. Moxibustion, in particular, became popular as a treatment that ordinary people could practice by themselves. Also in this period of isolation, Western medicine was imported from Holland, the only country allowed to maintain trade with Japan. This novel modern medicine had a strong impact on Japanese medicine, which has its foundation of Chinese traditional medicine. At the same time, Japanese acupuncture was introduced into Europe via Holland. When Japan opened its borders in 1865 period, the new government was eager to accept Western culture to the extent of prohibiting the progress of Japanese acupuncture for a period of time. Even so, Japanese acupuncture has survived and flourished up to the present day due to the strong demand and the great efforts of the practitioners. Scientific studies are now in the process of establishing a firm evidence base for over a millennium of clinical use, respecting the classic ideas of the traditional treatment.

Background Irritable bowel syndrome (IBS) is a common, costly, and difficult to treat disorder that impairs health-related quality of life and work productivity. Evidence-based treatment guidelines have been unable to provide guidance on the effects of acupuncture for IBS because the only previous systematic review included only small, heterogeneous and methodologically unsound trials. Objectives The primary objectives were to assess the efficacy and safety of acupuncture for treating IBS. Search methods MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE, the Cumulative Index to Nursing and Allied Health, and the Chinese databases Sino-Med, CNKI, and VIP were searched through November 2011. Selection criteria Randomized controlled trials (RCTs) that compared acupuncture with sham acupuncture, other active treatments, or no (specific) treatment, and RCTs that evaluated acupuncture as an adjuvant to another treatment, in adults with IBS were included. Data collection and analysis Two authors independently assessed the risk of bias and extracted data. We extracted data for the outcomes overall IBS symptom severity and health-related quality of life. For dichotomous data (e.g. the IBS Adequate Relief Question), we calculated a pooled relative risk (RR) and 95% confidence interval (CI) for substantial improvement in symptom severity after treatment. For continuous data (e.g. the IBS Severity Scoring System), we calculated the standardized mean difference (SMD) and 95% CI in post-treatment scores between groups. Main results Seventeen RCTs (1806 participants) were included. Five RCTs compared acupuncture versus sham acupuncture. The risk of bias in these studies was low.We found no evidence of an improvement with acupuncture relative to sham (placebo) acupuncture for symptom severity (SMD-0.11, 95%CI −0.35 to 0.13; 4 RCTs; 281 patients) or quality of life (SMD = −0.03, 95%CI −0.27 to 0.22; 3 RCTs; 253 patients).

Gynecology specialties focus particularly on menstrual and reproductive disorders. Both the adoption of the use of acupuncture outside Asia, and the incorporation of scientific analysis in Asia have challenged biomedical conceptions of what can be achieved with this treatment method. The scale of research activity in relation to acupuncture and women's health has increased over the last 20 years. Objective: This review aims to explore the research evidence in relation to acupuncture use for women's reproductive disorders, focusing on both clinical findings and experimental research on acupuncture's mechanisms of action in relation to women's health. Methods: A narrative literature search was undertaken using searches of electronic databases and manual searches of journals and textbooks. The search included all literature published prior to June 2013. The literature was assessed as to the nature of the study it was reporting and findings synthesized into a commentary. Results: For acupuncture's mechanism of action the search resulted in 114 relevant documents; in relation to clinical reports on the use of acupuncture for women's health 204 documents were found and assessed. Conclusion: There is preliminary data indicating acupuncture may improve menstrual health and coping for women experiencing delays falling pregnant. There is experimental data showing that acupuncture can influence female reproductive functioning, although the actual mechanisms involved are not yet clarified.

Acupuncture therapy for stroke patients.

Acupuncture is one of the most important parts of Traditional Chinese Medicine, has been used for more than 3000 years as prevention and treatment for various diseases in China as well as in adjacent regions, and is widely accepted in western countries in recent years. More and more clinical trials revealed that acupuncture shows positive effect in stroke, not only as a complementary and alternative medicine for poststroke rehabilitation but also as a preventive strategy which could induce cerebral ischemic tolerance, especially when combined with modern electrotherapy. Acupuncture has some unique characteristics, which include acupoint specificity and parameter-dependent effect. It also involves complicated mechanism to exert the beneficial effect on stroke. Series of clinical trials have shown that acupuncture primarily regulates the release of neurochemicals, hemorheology, cerebral microcirculation, metabolism, neuronal activity, and the function of specific brain region. Animal studies showed that the effects of acupuncture therapy on stroke were possibly via inhibition of postischemic inflammatory reaction, stimulation of neurogenesis and angiogenesis, and influence on neural plasticity. Mechanisms for its preconditioning effect include activity enhancement of antioxidant, regulation of the endocannabinoid system, and inhibition of apoptosis. Although being controversial, acupuncture is a promising preventive and treatment strategy for stroke, but further high-quality clinical trials would be needed to provide more confirmative evidence. © 2013 Elsevier Inc.

By analysing the defect of control design in randomized controlled trials (RCTs) of simple obesity treated with acupuncture and using acupuncture as the contrast, presenting the essential factors which should be taken into account as designing the control of clinical trial to further improve the clinical research. Setting RCTs of acupuncture treating simple obesity as a example, we searched RCTs of acupuncture treating simple obesity with acupuncture control. According to the characteristics of acupuncture therapy, this research sorted and analysed the control approach of intervention from aspects of acupoint selection, the penetration of needle, the depth of insertion, etc, then calculated the amount of difference factor between the two groups and analyzed the rationality. In 15 RCTs meeting the inclusion criterias, 7 published in English, 8 in Chinese, the amount of difference factors between two groups greater than 1 was 6 (40%), 4 published in English abroad, 2 in Chinese, while only 1 was 9 (60%), 3 published in English, 6 in Chinese. Control design of acupuncture in some clinical RCTs is unreasonable for not considering the amount of difference factors between the two groups.

Lack of TXNIP protects against mitochondria-mediated apoptosis but not against fatty acid-induced ER stress-mediated beta-cell death.

2010-02-01

We have previously shown that lack of thioredoxin-interacting protein (TXNIP) protects against diabetes and glucotoxicity-induced beta-cell apoptosis. Because the role of TXNIP in lipotoxicity is unknown, the goal of the present study was to determine whether TXNIP expression is regulated by fatty acids and whether TXNIP deficiency also protects beta-cells against lipoapoptosis. RESARCH DESIGN AND METHODS: To determine the effects of fatty acids on beta-cell TXNIP expression, INS-1 cells and isolated islets were incubated with/without palmitate and rats underwent cyclic infusions of glucose and/or Intralipid prior to islet isolation and analysis by quantitative real-time RT-PCR and immunoblotting. Using primary wild-type and TXNIP-deficient islets, we then assessed the effects of palmitate on apoptosis (transferase-mediated dUTP nick-end labeling [TUNEL]), mitochondrial death pathway (cytochrome c release), and endoplasmic reticulum (ER) stress (binding protein [BiP], C/EBP homologous protein [CHOP]). Effects of TXNIP deficiency were also tested in the context of staurosporine (mitochondrial damage) or thapsigargin (ER stress). Glucose elicited a dramatic increase in islet TXNIP expression both in vitro and in vivo, whereas fatty acids had no such effect and, when combined with glucose, even abolished the glucose effect. We also found that TXNIP deficiency does not effectively protect against palmitate or thapsigargin-induced beta-cell apoptosis, but specifically prevents staurosporine- or glucose-induced toxicity. Our results demonstrate that unlike glucose, fatty acids do not induce beta-cell expression of proapoptotic TXNIP. They further reveal that TXNIP deficiency specifically inhibits the mitochondrial death pathway underlying beta-cell glucotoxicity, whereas it has very few protective effects against ER stress-mediated lipoapoptosis.

Research into acupuncture has had ripple effects beyond the field of acupuncture. This paper identifies five exemplars to illustrate that there is tangible evidence of the way insights gleaned from acupuncture research have informed biomedical research, practice, or policy. The first exemplar documents how early research into acupuncture analgesia has expanded into neuroimaging research, broadening physiologic understanding and treatment of chronic pain. The second describes how the acupuncture needle has become a tool to enhance biomedical knowledge of connective tissue. The third exemplar, which illustrates use of a modified acupuncture needle as a sham device, focuses on emergent understanding of placebo effects and, in turn, on insights into therapeutic encounters in treatments unrelated to acupuncture. The fourth exemplar documents that two medical devices now in widespread use were inspired by acupuncture: transcutaneous electrical nerve stimulators for pain control and antinausea wrist bands. The final exemplar describes how pragmatic clinical trial designs applied in acupuncture research have informed current general interest in comparative effectiveness research. In conclusion, these exemplars of unanticipated outcomes of acupuncture research comprise an additional rationale for continued support of basic and clinical research evaluating acupuncture and other under-researched therapies.

The aim of this investigation was an immunohistochemical study of alpha-endorphin-producing cells and also a study of rat mast cells (MC in the antral mucosa of the human stomach. Men aged 18 to 30 years undergoing in-patient treatment wre studied. According to the results of radioimmunoassay, antibodies against alpha-endorphin did not react with enkephalins, beta-endorphin, or the C-terminal fragment of beta-endorphin, but had cross reactivity of about 10% with gammaendorphin. Results were subjected to statistical analysis by Student's test at a 85% level of significance and they are shown. The facts presented here suggest that MC of human gastric mucosa include argyrophilic cells which contain alpha-endorphin.

Full Text Available This paper examined the National Health Interview Survey (NHIS 2007 and explored acupuncture users sociodemographics characteristics, reasons and the nature of acupuncture use, and the relationship of such use with conventional medical care. All individuals who completed adults core interviews (N = 23,393 were included. Three subsets of samples (nonuser, former user, and recent user were used in the analysis performed in Stata. Our findings revealed that ever acupuncture user (including former and recent user increased from 4.2% to 6.3% of the population, representing 8.19 million and 14.01 million users in 2002 and 2007, respectively. We expected this trend to continue. People not only used acupuncture as a complementary and alternative approach to conventional treatment for a specific health condition, but also used it as a preventive means to promote general health. Effectiveness and safety appeared not to be the main predictors of acupuncture use; rather, awareness, cost, and insurance coverage played a bigger role in decision making.

We used synchrotron x-ray fluorescence analysis to probe the distribution of four chemical elements in and around acupuncture points, two located in the forearm and two in the lower leg. Three of the four acupuncture points showed significantly elevated concentrations of elements Ca, Fe, Cu and Zn in relation to levels in the surrounding tissue, with similar elevation ratios for Cu and Fe. The mapped distribution of these elements implies that each acupuncture point seems to be elliptical with the long axis along the meridian.

Cardiac injury is the most serious adverse event in acupuncture therapy. The causes include needling chest points near the heart, the cardiac enlargement and pericardial effusion that will enlarge the projected area on the body surface and make the proper depth of needling shorter, and the incorrect needling method of the points. Therefore, acupuncture practitioners must be familiar with the points of the heart projected area on the chest and the correct needling methods in order to reduce the risk of acupuncture therapy related cardiac injury.

"Warming yang and invigorating qi" acupuncture alters acetylcholine receptor expression in the neuromuscular junction of rats with experimental autoimmune myasthenia gravis

Hai-peng Huang

2016-01-01

Full Text Available Myasthenia gravis is an autoimmune disorder in which antibodies have been shown to form against the nicotinic acetylcholine nicotinic postsynaptic receptors located at the neuromuscular junction. "Warming yang and invigorating qi" acupuncture treatment has been shown to reduce serum inflammatory cytokine expression and increase transforming growth factor beta expression in rats with experimental autoimmune myasthenia gravis. However, few studies have addressed the effects of this type of acupuncture on the acetylcholine receptors at the neuromuscular junction. Here, we used confocal laser scanning microscopy to examine the area and density of immunoreactivity for an antibody to the nicotinic acetylcholine receptor at the neuromuscular junction in the phrenic nerve of rats with experimental autoimmune myasthenia gravis following "warming yang and invigorating qi" acupuncture therapy. Needles were inserted at acupressure points Shousanli (LI10, Zusanli (ST36, Pishu (BL20, and Shenshu (BL23 once daily for 7 consecutive days. The treatment was repeated after 1 day of rest. We found that area and the integrated optical density of the immunoreactivity for the acetylcholine receptor at the neuromuscular junction of the phrenic nerve was significantly increased following acupuncture treatment. This outcome of the acupuncture therapy was similar to that of the cholinesterase inhibitor pyridostigmine bromide. These findings suggest that "warming yang and invigorating qi" acupuncture treatment increases acetylcholine receptor expression at the neuromuscular junction in a rat model of autoimmune myasthenia gravis.

To observe the effect of acupuncture of Zusanli (ST 36) on electroencephalogram (EEG) so as to probe into its law in regulating the interconnectivity of brain functional network. A total of 9 healthy young volunteer students (6 male, 3 female) participated in the present study. They were asked to take a dorsal position on a test-bed. EEG signals were acquired from 22 surface scalp electrodes (Fp1, Fp2, F7, F3, F2, F4, F8, A1, T3, C3, C2, C4, T4, A2, T5, P3, P2, P4, T6, O2, O1 and O2) fixed on the subject's head. Acupuncture stimulation was applied to the right Zusanli (ST 36) by manipulating the filiform needle with uniform reducing-reinforcing method and at a frequency of about 50 cycles/min for 2 min. Then the stimulation was stopped for 10 min, and repeated once again (needle-twirling frequency: 150 and 200 cycles/min), 3 times altogether. The acquired EEG data were analyzed by using coherence estimation method, average path length, average clustering coefficient, and the average degree of the articulation points (nodes) for analyzing the synchronization of EEG signals before, during and after acupuncture. In comparison with pre-acupuncture, the coherence amplitude values of EEG-delta (1-4 Hz) and y (31-47 Hz) waves were increased significantly after acupuncture of ST 36. No significant changes were found in the amplitude values of EEG-theta (5-8 Hz), -alpha (9-13 Hz) and-beta (14-30 Hz) waves after acupuncture stimulation. During and after acupuncture, the synchronism values of EEG-delta waves of different leads and numbers of interconnectivity between every two brain functional regions in majority of the 9 volunteers were increased clearly. In all volunteers, the degree values of all nodes except A1 and A2, the average clustering coefficients along with the increase of the threshold (r), and the average path lengths of the brain functional network of EEG-delta waves during and after acupuncture were also increased evidently (the latter two items, P < 0

Three points on the inheritance,innovation and belongingness of acupuncture-moxibustion research are discussed in the paper,including the inheritance of acupuncture-moxibustion culture showing the soul of the development of acupuncture,the improvement of acupuncture-moxibustion presenting the close relationship with the innovation and its development belonging to the origin. It is considered that the inheritance of acupuncture-moxibustion culture takes the priority of its development. Innovation must be realized in order to exist better in the future medicine. The study of acupuncture-moxibustion can not be limited to the traditional acupuncture-moxibustion theory,but need to be in line with it. Explore actively the value of traditional acupuncture-moxibustion culture and its theory. The research and education of acupuncture-moxibustion must belong to TCM. With all the above condition,the innovation and development of acupuncture-moxibustion could be better achieved.

Nowadays extensive attention has been paid on the research of acupuncture academic schools, however, a widely accepted method of partition of acupuncture academic schools is still in need. In this paper, the methods of partition of acupuncture academic schools in the history have been arranged, and three typical methods of"partition of five schools" "partition of eighteen schools" and "two-stage based partition" are summarized. After adeep analysis on the disadvantages and advantages of these three methods, a new method of partition of acupuncture academic schools that is called "three-stage based partition" is proposed. In this method, after the overall acupuncture academic schools are divided into an ancient stage, a modern stage and a contemporary stage, each schoolis divided into its sub-school category. It is believed that this method of partition can remedy the weaknesses ofcurrent methods, but also explore a new model of inheritance and development under a different aspect through thedifferentiation and interaction of acupuncture academic schools at three stages.

Harmonic Medicine is the model using the theory that the body rhythms synchronize to an outer rhythm applied for therapeutic purpose, can restores the energy balance in acupuncture channels and organs and the condition of well-being. The purpose of this scientific work was to demonstrate the role played by harmonic sounds in the stimulation of the Lung (LU) Meridian (Shoutaiyin Feijing) and of the Kidney (KI) Meridian (Zushaoyin Shenjing). It was used an original method that included: measurement and electronic sound stimulation of the Meridian Entry Point, measurement of Meridian Exit Point, computer data processing, bio feed-back adjustment of the music stimulation parameters. After data processing, it was found that the sound stimulation of the Lung Meridian Frequency is optimal between 122 Hz and 128 Hz, with an average of 124 Hz (87% of the subjects) and for Kidney Meridian from 118 Hz to 121 Hz, with an average of 120 Hz (67% of the subjects). The acupuncture stimulation was more intense for female subjects (> 7%) than for the male ones. We preliminarily consider that an informational resonance phenomenon can be developed between the acupuncture music stimulation frequency and the cellular dipole frequency, being a really "resonant frequency signature" of an acupoint. The harmonic generation and the electronic excitation or low-excitation status of an acupuncture point may be considered as a resonance mechanism. By this kind of acupunctural stimulation, a symphony may act and play a healer role.

Acupuncture is a medical procedure with a very wide range of indications according to the WHO. However the indications require robust scientific evidence to support them. We have conducted a systematic review (2010-2015) in order to define in which pathologies acupuncture can be an effective strategy, STRICTA criteria that aim to set up acupuncture clinical trials standard criteria were defined in 2010. Only systematic reviews and meta-analyses of good or very good methodological quality according to SIGN criteria were selected. Its main objective was to evaluate the effectiveness of acupuncture in the management of any disease. Most of the final 31 selected reviews focus on chronic pain-related diseases, mainly in the disciplines of Neurology, Orthopaedics and Rheumatology. Current evidence supports the use of acupuncture in the treatment of headaches, migraines, back pain, cervical pain and osteoarthritis. The remaining pathologies still require further good quality studies. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Acupuncture therapy on PC 6 (Neiguan) has a therapeutic effect on cardiac and chest ailments including angina pectoris. Additional beneficial acupuncture points are PC 4 (Ximen), HT 7 (Shenmen point), PC 7 (Daling point), PC 5 (Jianshi point), PC 3 (Quze point), CV 17 (Danzhong point), CV 6 (Qihai point), BL 15 (Xinshu point), L 20 (Pishu point), BL 17 (Geshu point), BL23 (Shenshu point), BL18 (Ganshu point), HT 5 (Tongli point), and ST36 (Zusanli point). Acupuncture not only quickly relieve the symptoms of acute angina pectoris, but also improve nitroglycerine's therapeutic effects. Therefore, it is an efficient simple therapeutic method used for emergency and for regular angina treatment. Review of studies on acupuncture therapy has shown effectiveness were between 80% to 96.2% that are almost as effective as conventional drug regimen. When compared with conventional medical treatment, the acupuncture therapy shows the obvious advantage of lacking, adverse side effects commonly associated with the Western anti-anginal drugs such as 1) Nitroglycerine (headache--63% with nitroglycerine patch and 50% with spray; syncope--4%; and dizziness--8% with patch; hypotension--4% with patch; and increased angina 2% with patch). 2) Isosorbide mononitrate (dizziness--3 to 5%; nausea/vomiting--2 to 4% and other reactions including hypotension, and syncope even with small doses). 3) Propranolol (bradycardia, chest pain, hypotension, worsening of AV conduction disturbance, Raynaud's syndrome, mental depression, hyperglycemia, etc.). Many conventional anti-anginal medications cause inter-drug reactions with other medications the patients taking for other diseases. Whereas, acupuncture therapy does not pose such an interference with patient's medications. Nevertheless, surgery is still the treatment of choice when acupuncture or conventional drug therapy fails. Combination of conventional drug therapy and acupuncture would considerably decrease the frequency and the required dosage

Acupuncture is becoming increasingly popular in the United States for a wide variety of uses, ranging from the treatment of chronic back pain to aiding in addiction therapy. As this form of complementary and alternative medicine becomes more prevalent in certain areas of the country, it is of paramount importance that the emergency physician be familiar with its methods and potential complications. In general, acupuncture is perceived as fairly safe. However, it is not without risks or side effects. In this case report, we discuss the history, methods, and common complications of acupuncture in the context of a patient who presented to the Emergency Department (ED) with bilateral pneumothoraces secondary to acupuncture therapy.

Spotlight on acupuncture in laboratory animal medicine

Full Text Available Elizabeth R Magden Department of Veterinary Sciences, Michale E Keeling Center for Comparative Medicine and Research, University of Texas MD Anderson Cancer Center, Bastrop, TX, USA Abstract: Acupuncture has been practiced for thousands of years, although it is only in the past century that science has worked to unravel the mechanisms behind its use. Literature supporting the efficacious use of acupuncture to treat a variety of conditions has been and continues to be published, including the randomized controlled studies we all appreciate when practicing evidence-based medicine. The use of acupuncture in veterinary medicine has paralleled the trends observed in people, with an increasingly common use to remedy specific medical conditions. These conditions are commonly related to neurological dysfunction or orthopedic pain. Although pain relief is the most common use of acupuncture, numerous other conditions have been shown to improve with this therapy. Laboratory animals are also benefiting from acupuncture. Its use is starting to be incorporated into research settings, although there is still further progress to be made in this field. Acupuncture has been shown to improve clinical conditions and quality of life in laboratory animals, and should be considered as a tool to treat laboratory animals with conditions known to benefit from therapy. Here we review the history, mechanisms of action, and use of acupuncture to treat veterinary patients and laboratory animals. Keywords: acupuncture, laboratory animals, nonhuman primates

Acupuncture in ancient China: how important was it really?

Science.gov (United States)

Lehmann, Hanjo

2013-01-01

Although acupuncture theory is a fundamental part of the Huangdi Neijing, the clinical application of the needle therapy in ancient China was always a limited one. From early times there have been warnings that acupuncture might do harm. In books like Zhang Zhongjing's Shanghanlun it plays only a marginal role. Among the 400 emperors in Chinese history, acupuncture was hardly ever applied. After Xu Dachun called acupuncture a "lost tradition" in 1757, the abolition of acupuncture and moxibustion from the Imperial Medical Academy in 1822 was a radical, but consequent act. When traditional Chinese medicine was revived after 1954, the "New Acupuncture" was completely different from what it had been in ancient China. The conclusion, however, is a positive one: The best time acupuncture ever had was not the Song dynasty or Yuan dynasty, but is now - and the future of acupuncture does not lie in old scripts, but in ourselves.

Full Text Available Acupuncture was introduced to Australia as early as in the 1880s, and is a form of complementary and alternative medicine in this country. In the past 2 decades since the 1990s, acupuncture has experienced a rapid growth. Today, nearly 4000 acupuncturists are registered with the Chinese Medicine Board of Australia. “Acupuncturist,” “Oriental medicine practitioner,” and “Chinese medicine practitioners” are protected titles for registered acupuncturists. A bachelor's degree of 4 years in related fields is the minimal requirement for registration in Australia. Three public universities and three major private colleges offer nine undergraduate and three postgraduate programs that are approved by the Chinese Medicine Board of Australia. Those three universities also offer Master-degree and Doctor of Philosophy programs. Acupuncture is well accepted by the Australians, with 10% having received this treatment and 80% general medical practitioners referring their patients to acupuncture service. All private health insurance schemes provide rebates to patients receiving acupuncture treatment, and third-party payment is also available in six of eight Australian states and territories. Research output in acupuncture has increased greatly since 2000. A majority of research focuses on acupuncture and Tai Chi as treatment modalities, and mainly investigates their mechanism of action, associated pain, and gynecological and respiratory conditions. The future direction of acupuncture in Australia is to introduce this medicine in hospitals and gain access to the medical benefit scheme so that acupuncture can be accessed by a wider community, in particular those who come from a disadvantaged background. In conclusion, improved education, regulation, and research of acupuncture in Australia put this country in a leading position among Western countries with respect to acupuncture services.

Acupuncture for Chronic Pain in Japan: A Review

2007-01-01

Full Text Available Many Japanese reports of acupuncture and moxibustion for chronic pain are not listed in medical databases such as Medline. Therefore, they are not easily accessible to researchers outside of Japan. To complement existing reviews of acupuncture and moxibustion for chronic pain and to provide more detailed discussion and analysis, we did a literature search using ‘Igaku Chuo Zasshi Wed’ (Japana Centra Revuo Medicina and ‘Citation Information by National Institute of Information’ covering the period 1978–2006. Original articles and case reports of acupuncture and moxibustion treatment of chronic pain were included. Animal studies, surveys, and news articles were excluded. Two independent reviewers extracted data from located articles in a pre-defined structured way, and assessed the likelihood of causality in each case. We located 57 papers written in Japanese (20 full papers, 37 case reports. Conditions examined were headache (12 trials, chronic low back pain (9 trials, rheumatoid arthritis (8 trials, temporomandibular dysfunction (8 trials, katakori (8 trials and others (12 trials. While 23 were described as clinical control trials (CCTs, 11 employed a quasi-random method. Applying the 5-point Jadad quality assessment scoring system, the mean score was 1.5 ± 1.3 (SD. Eleven (52% of the CCTs were conducted to determine a more effective procedure for acupuncture; these compared a certain type of acupuncture with another type of acupuncture or specific additional points. In particular, the trigger point acupuncture was widely used to treat chronic low back pain in Japan. Many reports of chronic pain treatment by acupuncture and moxibustion are listed in Japanese databases. From the data, we conclude that there is limited evidence that acupuncture is more effective than no treatment, and inconclusive evidence that trigger point acupuncture is more effective than placebo, sham acupuncture or standard care.

Effect of endogenous androgens on 17beta-estradiol-mediated protection after spinal cord injury in male rats.

Several groups have recently shown that 17beta-estradiol is protective in spinal cord injury (SCI). Testosterone can be aromatized to 17beta-estradiol and may increase estrogen-mediated protection. Alternatively, testosterone has been shown to increase excitotoxicity in models of central nervous system (CNS) injury. These experiments test the hypothesis that endogenous testosterone in male rats alters 17beta-estradiol-mediated protection by evaluating a delayed administration over a clinically relevant dose range and manipulating testicular-derived testosterone. Adult male Sprague Dawley rats were either gonadectomized or left gonad-intact prior to SCI. SCI was produced by a midthoracic crush injury. At 30 min post SCI, animals received a subcutaneous pellet of 0.0, 0.05, 0.5, or 5.0 mg of 17beta-estradiol, released over 21 days. Hindlimb locomotion was analyzed weekly in the open field. Spinal cords were collected and analyzed for cell death, expression of Bcl-family proteins, and white-matter sparing. Post-SCI administration of the 0.5- or 5.0-mg pellet improved hindlimb locomotion, reduced urinary bladder size, increased neuronal survival, reduced apoptosis, improved the Bax/Bcl-xL protein ratio, and increased white-matter sparing. In the absence of endogenous testicular-derived androgens, SCI induced greater apoptosis, yet 17beta-estradiol administration reduced apoptosis to the same extent in gonadectomized and gonad-intact male rats. These data suggest that delayed post-SCI administration of a clinically relevant dose of 17beta-estradiol is protective in male rats, and endogenous androgens do not alter estrogen-mediated protection. These data suggest that 17beta-estradiol is an effective therapeutic intervention for reducing secondary damage after SCI in males, which could be readily translated to clinical trials.

This paper reviews the history of acupuncture's dissemination to Japan, France, and England in the modern period. In particular, it examines how Chinese acupuncture methods were modified in each of these countries and how these modifications were theoretically justified based on new readings of classical texts. In each country, these currents of acupuncture practice all claimed to be transmitting true traditional acupuncture, even as they developed along different trajectories and created new and different theories and practices of acupuncture. Some of these foreign methods were re-exported back to China, where they, in turn, have influenced the development of Chinese acupuncture.

Beta1 integrin-mediated adhesion signalling is essential for epidermal progenitor cell expansion.

Directory of Open Access Journals (Sweden)

Aleksandra Piwko-Czuchra

Full Text Available BACKGROUND: There is a major discrepancy between the in vitro and in vivo results regarding the role of beta1 integrins in the maintenance of epidermal stem/progenitor cells. Studies of mice with skin-specific ablation of beta1 integrins suggested that epidermis can form and be maintained in their absence, while in vitro data have shown a fundamental role for these adhesion receptors in stem/progenitor cell expansion and differentiation. METHODOLOGY/PRINCIPAL FINDINGS: To elucidate this discrepancy we generated hypomorphic mice expressing reduced beta1 integrin levels on keratinocytes that developed similar, but less severe defects than mice with beta1-deficient keratinocytes. Surprisingly we found that upon aging these abnormalities attenuated due to a rapid expansion of cells, which escaped or compensated for the down-regulation of beta1 integrin expression. A similar phenomenon was observed in aged mice with a complete, skin-specific ablation of the beta1 integrin gene, where cells that escaped Cre-mediated recombination repopulated the mutant skin in a very short time period. The expansion of beta1 integrin expressing keratinocytes was even further accelerated in situations of increased keratinocyte proliferation such as wound healing. CONCLUSIONS/SIGNIFICANCE: These data demonstrate that expression of beta1 integrins is critically important for the expansion of epidermal progenitor cells to maintain epidermal homeostasis.

Acupuncture Mechanisms: Anesthesia, Analgesia and Protection on Organ Functions

Directory of Open Access Journals (Sweden)

Jing Wang

2015-01-01

Full Text Available Acupuncture, as a healing art in traditional Chinese medicine, has been widely used to treat various diseases. In the history of acupuncture anesthesia, in the past decades, mechanisms of acupuncture analgesia has been widely investigated, and in recent years, acupuncture protection on organ functions has attracted great interest. This review summarized the research progress on mechanisms of acupuncture for analgesia and its protection against organ function injury in anesthesia, and its perspective of analgesia, immunomodulation, neuroendocrine regulation and multiple organ protection. The current evidence supports that acupuncture analgesia and its organ protection in anesthesia is associated with the integration of neuroendocrine-immune networks in the level of neurotransmitters, cytokines, hormones, neuronal ensembles, lymphocytes, and endocrine cells. Although the mechanisms of acupuncture analgesia and its organ protection are still not completely understood, basic as well as clinic researches on the mechanisms and applications of acupuncture and related techniques are being carried out.

As an analogy, a prototype of "bell-striking" is proposed in the present paper for exploring the basic properties, major elements, and potential mechanisms of acupuncture stimulation. On the strength of analysis on the physiological basis of acupuncture effect, several fundamental aspects of acupuncture are summarized as a) the body-surface stimulating characters, b) general and local effects, and c) triggering the auto-regulative function of the organism, which mimics the "bell-striking" response. Namely, when stroke, bell will chime, otherwise, chiming will not be heard. During analyzing special contents of acupuncture theory, its formative background should not be separated, and it is improper to take, modern medical theory of the human body as the guiding thinking way for researching the ancient Chinese medical literature.

This study aims to explore the potential use of ultrasound in locating the second posterior sacral foramen acupuncture point, quantifying depth of insertion and describing surrounding anatomical structures. We performed acupuncture needle insertion on a study team member. There were four steps in our experiment. First, the acupuncturist located the acupuncture point by palpation. Second, we used an ultrasound machine to visualize the structures surrounding the location of the acupuncture point and measure the depth required for needle insertion. Third, the acupuncturist inserted the acupuncture needle into the acupuncture point at an angle of 30°. Fourth, we performed another ultrasound scan to ensure that the needle was in the desired location. Results suggested that ultrasound could be used to locate the acupuncture point and estimate the depth of needle insertion. The needle was inserted to a depth of 4.0 cm to reach the surface of the sacral foramen. Based on Pythagoras theorem, taking a needle insertion angle of 30° and a needle insertion depth of 4.0 cm, the estimated perpendicular depth is 1.8 cm. An ultrasound scan corroborated the depth of 1.85 cm. The use of an ultrasound-guided technique for needle insertion in acupuncture practice could help standardize the treatment. Clinicians and students would be able to visualize and measure the depth of the sacral foramen acupuncture point, to guide the depth of needle insertion. This methodological guide could also be used to create a standard treatment protocol for research. A similar mathematical guide could also be created for other acupuncture points in future.

To compare the clinical efficacy differences between warming acupuncture and conventional acupuncture for diabetic peripheral neuropathy (DPN) with syndrome of yang deficiency and cold coagulation, obstruction of collaterals and blood stasis. A total of 64 patients were randomly divided into a warming acupuncture group and a conventional acupuncture group, 32 cases in each one. Based on basic treatment of blood glucose regulation, warming acupuncture was applied at Pishu (BL 20), Shenshu (BL 23), Guanyuanshu (BL 26), Zusanli (ST 36), Chongyang (ST 42), Quchi (LI 11) and Hegu (LI 4) in the warming acupuncture group, while acupuncture was applied at the identical acupoints in the conventional acupuncture group. Both the treatments were given once a day with an interval of one day every six days; totally the treatment was given for 4 weeks. The TCM symptom score, Toronto clinical scoring system (TCSS) and nerve conduction velocity (NCV) before and after treatment were compared in the two groups. After treatment, the TCM symptom scores in the two groups were significantly reduced (both P nervus peroneus communis, as well as sensory nerve of tibial nerve and sural nerve was improved in the warming acupuncture group (all P 0.05). Warming acupuncture and conventional acupuncture could both increase TCM symptom score, improve NCV in patients of DPN with syndrome of yang deficiency and cold coagulation, obstruction of collaterals and blood stasis; warming acupuncture has advantage in symptom improvement.

Validation of electro-thermal simulation with experimental data to prepare online operation of a molten salt target at ISOLDE for the Beta Beams

The main objective of the Beta Beams is to study oscillation property of pure electrons neutrinos. It produces high energy beams of pure electron neutrinos and anti-neutrinos for oscillation experiments by beta decay of He-6 and Ne-18 radioactive ion beams, stored in a decay ring at gamma = 100. The production of He-6 beam has already been accomplished using a thick beryllium oxide target. However, the production of the needed rate of Ne-18 has proven to be more challenging. In order to achieve the requested yield for Ne-18 a new high power target design based on a circulating molten salt loop has been proposed. To verify some elements of the design, a static molten salt target prototype has been developed at ISOLDE and operated successfully. This paper describes the electro-thermal study of the molten salt target taking into account the heat produced by Joule effect, radiative heat exchange, active water cooling due to forced convection and air passive cooling due to natural convection. The numerical results...

To investigate the effect of electro-acupuncture (EA) as a non-pharmacological intervention to prevent or reduce chemotherapy-induced peripheral neuropathy (CIPN) in breast cancer patients undergoing chemotherapy of taxane. Women with stage I-III breast cancer scheduled to receive taxane therapy were randomized to receive a standardized protocol of 12 true or sham EA (SEA) weekly treatments concurrent with taxane treatment. Subjects completed the Brief Pain Inventory-Short Form (BPI-SF), Functional Assessment of Cancer Therapy-Taxane neurotoxicity subscale (FACT-NTX), and other assessments at baseline and weeks 6, 12, and 16. A total of 180 subjects were screened, 63 enrolled and 48 completed week 16 assessments. Mean age was 50 with 25 % white, 25 % black, and 43 % Hispanic; 52 % had no prior chemotherapy. At week 12, both groups reported an increase in mean BPI-SF worst pain score, but no mean differences were found between groups (SEA 2.8 vs. EA 2.6, P = .86). By week 16, the SEA group returned to baseline, while the EA group continued to worsen (SEA 1.7 vs. EA 3.4, P = .03). The increase in BPI-SF worst pain score was 1.62 points higher in the EA group than in the SEA group at week 16 (P = .04). In a randomized, sham-controlled trial of EA for prevention of taxane-induced CIPN, there were no differences in pain or neuropathy between groups at week 12. Of concern, subjects on EA had a slower recovery than SEA subjects. Future studies should focus on EA for treatment as opposed to prevention of CIPN.

To identify socio-demographic and health-related factors associated with (a) acupuncture use and (b) the rated helpfulness of acupuncture among internal medicine patients. Data from a larger cross-sectional trial were reanalyzed. Patients who had used acupuncture for managing their primary medical complaint were compared to patients who had not. Predictors for (a) acupuncture use and (b) rated helpfulness were determined using logistic regression analyses. Of 2486 included patients, 51.49% reported acupuncture use and 39.22% reported no prior use. The use of acupuncture was associated with higher age, i.e. those aged 50-64 were more likely to have used acupuncture, while those younger than 30 were less likely. Patients with spinal pain, fibromyalgia, or headache were more likely to be acupuncture users; while IBS patients were less likely. Patients with good to excellent health status, high external-social health locus of control and current smokers were less likely to have used acupuncture. Among those who had used acupuncture, 42.34% perceived the treatment as helpful, while 35.94% did not. Rated helpfulness was associated with female gender, full-time employment, high health satisfaction, and high internal health locus of control. Those with a diagnosis of osteoarthritis or inflammatory bowel disease were more likely to find acupuncture helpful; those with headache or other types of chronic pain were less likely to find acupuncture helpful. Acupuncture was used by more than half of internal medicine patients. Prevalence and rated helpfulness of acupuncture use was associated with the patients' medical condition, sociodemography, and health locus of control. Copyright © 2015 Elsevier Ltd.

To evaluate the short-term efficacy of acupuncture for the treatment of peri-menopausal insomnia (PMI). Design: A randomized, participant-blind, placebo-controlled trial consisted of the acupuncture group (n = 38) and placebo-acupuncture group (n = 38). Setting: A tertiary teaching and general hospital. Participants: 76 peri-menopausal women with insomnia disorder based on the International Classification of Sleep Disorders, Third Edition. Interventions: A 10-session of acupuncture at bilateral Shenshu (BL 23) and Ganshu (BL 18) with unilateral Qimen (LR 14) and Jingmen (GB 25) or Streitberger needles at the same acupoints was performed for over 3 weeks. Measurements: Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) with over-night polysomnography (PSG) exam were completed at baseline and post-treatment. After the treatments, the decrease from baseline in PSQI score was 8.03 points in acupuncture group and 1.29 points in placebo-acupuncture group. The change from baseline in ISI score was 11.35 points in acupuncture group and 2.87 points in placebo-acupuncture group. In PSG data, acupuncture significantly improved the sleep efficiency and total sleep time, associated with less wake after sleep onset and lower percent stage 1 after the treatment.

2013-01-01

Alzheimer's disease is the most common form of dementia diagnosed in the aging population worldwide. The cause of Alzheimer's is still not clear. There is no cure for the disease and current treatments are only symptomatic relieve. The search for new treatment is made ever more urgent due to increasing population aging. Acupuncture has been in practice in China for more than 3000 years and used to treat a wide variety of conditions including cardiovascular and psychiatric diseases, acute, and chronic pain. In this chapter, we review recent development on the effects and mechanisms of acupuncture on Alzheimer's disease. In Alzheimer's animal models, acupuncture stimulation at acupoints enhances cholinergic neurotransmission, trophic factor releasing, reduces apoptotic and oxidative damages, improves synaptic plasticity and decreases the levels of Aβ proteins in the hippocampus and relevant brain regions. The biochemical modulations by acupuncture in the brains of Alzheimer's models are correlated with the cognitive improvement. In Alzheimer's patients, functional brain images demonstrated that acupuncture increased in the activity in the temporal lobe and prefrontal lobe which are related to the memory and cognitive function. Although only a few acupuncture clinical studies with a small number of participants are reported, they represent an important step forward in the research of both acupuncture and Alzheimer's. Translation of acupuncture research in animal model studies into the human subjects will undoubtedly enhance acupuncture efficacy in clinical study and treatment which could eventually lead to a safer, well-tolerated and inexpensive form of care for Alzheimer's patients. © 2013 Elsevier Inc.

Chen, Teng-Fei; Ma, Zeng-Bin; Xin, Si-Yuan; Zhu, Jiang

2013-08-01

Taking Doctor HUANG Shi-ping as the representative, the school of Huang's golden needle is based on Chinese martial art. Golden needles are adopted as main tool. Attaching great importance on the combination of acupuncture and moxibustioin, it is also characterized with penetrating needling with long needles. Through the development of three generations, it once outshone other schools in the field of acupuncture, and became famous all over the world. It made great contribution to the development of the course of acupuncture. However, with the development of the history, the form of acupuncture education as well as apparatus were all undergone an unified reform. Therefore, Doctor HUANG Shi-ping's acupuncture school be lost gradually.

Full Text Available Acupuncture, with its unique set of theories and its evident results in clinical practice is an important part of traditional Chinese medicine (TCM, and gaining recognition worldwide for the past few years. Although acupuncture treatment is generally accepted by the public, a few western researchers believe that sufficient evidence of its efficiency is still currently lacking, therefore creating a challenge of its acceptance on a wider scale. This article suggests the concepts of acupuncture behind clinical researches by reviewing the clinical researches done, analyzing the existing problems, and integrating real life acupuncture into the research process. By increasing the credibility of acupuncture, its reach can be extended globally and to more countries and regions.

[Theoretical origin and clinical application of wrist-ankle acupuncture therapy].

Science.gov (United States)

Wang, Qiong; Zhou, Qinghui

2017-05-12

The theory of wrist-ankle acupuncture is consistent with traditional meridian-collateral theory. For example, the body divisions of wrist-ankle acupuncture are corresponding to the distribution of 12 cutaneous regions of meridians, the needling sites of it are to the running courses of 12 meridians; the indications of it are to those of 12 meridians. The needling sites of wrist-ankle acupuncture are relevant with some special acupoints of acupuncture theory. For example, the 12-needling sites of wrist-ankle acupuncture are located similar to those of 12 meridian points and have very similar indications. The needling sites of it are located in the wrist and ankle regions, in which the five- shu points are located nearby, for meridian disorders. Most luo -connecting points are located near to the needling sites of wrist-ankle acupuncture or the needle tip points to. Additionally, the needling method of wrist-ankle acupuncture is consistent with some of the subcutaneous needling methods in traditional acupuncture therapy. On the basis of the aspects mentioned above, it is explained that wrist-ankle acupuncture is the development of traditional acupuncture and cannot be independent from the traditional theories of acupuncture and meridians. It is necessary to seek for the evidence from the traditional theories of TCM. The traditional theories of TCM are summarized from clinical practice, which can be newly verified from the practice of wrist-ankle acupuncture.

Investigation of acupuncture-point injection combined with intratumor injection of radionuclide phosphorus 32 in treatment of metastatic carcinoma

Chou, H.C.

1986-01-01

Seventeen patients with carcinoma and three patients with benign lesions of the head were studied by acupuncture-point injection combined with intratumor injection of radionuclide P-32 for treatment of metastatic carcinoma. The metastatic cervical nodules shrank to half their original sizes within 2-3 weeks in five cases of nasopharyngeal carcinoma. The injected dose ranged from 0.222 to 0.421 mCi, approximately 10 times less than that given by the ordinary method. The acupuncture points are selected according to the Theory of Channels and Collaterals of Chinese traditional medicine. The mechanism of therapeutic action of radionuclide P-32 is possibly by the delivery of destructive ionizing radiation from beta emission properties of P-32. This method appears to offer a low-dose means of P-32 treatment of metastatic carcinoma

The development history, education, legislation, charge and institutes of acupuncture and moxibustion in Singapore are introduced in this article. Acupuncture and moxibustion has been developed in Singapore since 1840. Nowadays there are three universities that set up standard Chinese medicine courses and two acupuncture-moxibustion associations. Legislation of acupuncture and moxibustion is published in 2000. The acupuncture and moxibustion is applied for approximately 50 kinds of diseases. The acupuncture and moxibustion is at one's own expense in public or private institutions, but cheap or completely free in charity.

Differential effects of whole-body γ-irradiation on antinociception induced by morphine and β-endorphin administered intracerebroventricularly in the mouse

International Nuclear Information System (INIS)

Kim, J.K.; Chung, K.M.; Park, T.W.

2000-01-01

Two separate lines of evidence suggested the present study. First, intracerebroventricularly (i.c.v.) administered morphine (a μ-opioid receptor agonist) and β-endorphin (an ε-opioid receptor agonist) produce antinociception by activating different descending pain inhibitory systems. Second, γ-irradiation attenuates the acute antinociceptive action of i.c.v. injected morphine, but not DPLPE (a δ-opioid receptor agonist), in mice. These findings prompted us to investigate the effect of γ-irradiation on the antinociception produced by i.c.v. injected morphine and β-endorphin in male ICR mice. In one group, mice were exposed to whole-body irradiation at a dose of 5 Gy from a 60 Co γ-source and the antinociceptive effects were tested 5, 30, 60,90 and 180 min after irradiation using the 1% acetic acid-induced writhing test (10 ml/kg). The antinociceptive effect was produced time-dependently and reached its maximum at 90 min after irradiation. Thus, time was fixed in the following studies. In another group, mice were irradiated with 5 Gy and tested 90 minutes later for antinociception produced by i.c.v. administration of morphine (50 and 100 ng/mouse) or β-endorphin (31 ng/mouse). Irradiation significantly potentiated the antinociception produced by β-endorphin. However, the antinociception produced by morphine was not affected by irradiation. These results demonstrate a differential sensitivity of μ- and ε-opioid receptors to γ-irradiation, in addition, support the hypothesis that morphine and β-endorphin administered supraspinally produce antinociception by different neuronal mechanisms.

Abstract Background: Overactive bladder is stated as the occurrence of urinary urgency which will cause negative impacts and decrease patients’ health-related quality of life. The aim of this systematic review is to assess the efficiency and safety of acupuncture for adults with overactive bladder (OAB) comparing with sham-acupuncture, drugs, and acupuncture plus drugs. Methods: We independently searched 9 databases from beginning to August 15, 2017. Two writers extracted data at the same time independently. Study outcomes were calculated by standardized mean differences (SMD) with 95% confidence intervals (CIs) and mean difference (MD) with 95% CIs. Results: Ten randomized controlled trials (RCTs) with 794 patients were included in this systematic review. The combined results showed that electroacupuncture (EA) may be more effective than sham electroacupuncture (sham EA) in improving the 24-hour nocturia episodes and EA may enhance tolterodine for relieving voiding symptoms and enhancing patients’ quality of life. However, more trials with high quality and larger sample sizes will be needed in the future to provide sufficient evidence. Only 15 of 794 OAB patients from the included studies reported mild adverse reactions related to EA, therefore, acupuncture is safe for treating OAB. Conclusion: Acupuncture might have effect in decreasing the number of micturition episodes, incontinence episodes, and nocturia episodes. However, the evidence is insufficient to show the effect using acupuncture alone or the additional effect to drugs in treating OAB. PMID:29465566

This study evaluated clinical outcomes following acupuncture treatment of postpartum sciatica. One hundred eleven women with postpartum sciatica were enrolled in an acupuncture group (n = 86) or a control group (n = 25), according to their preference. Participants in the acupuncture group attended acupuncture therapy sessions 3 times a week for 4 weeks, while participants in the control group were assigned to bed rest. Outcome measures included the Roland Disability Questionnaire for sciatica, a visual analog scale for leg pain, and patient-reported perceived recovery. In addition, participants were surveyed after treatment to assess the acceptability of acupuncture therapy. The outcome scores for disability and leg pain were significantly lower in the acupuncture group compared with the control group (P acupuncture improved their well-being after treatment. At one month after treatment, 98% of participants in the treatment group reported recovery compared with 24% of the control group participants (P acupuncture group believed that acupuncture had no significant interference with breast milk production. No adverse effects of acupuncture were reported. All participants in the acupuncture group stated they would choose acupuncture in case of relapse. However, the recurrence rate of sciatica in the acupuncture group (32%) was comparable to that of the control group (35%) at the one-year follow-up interview. Compared with bed rest, acupuncture might be an effective and acceptable strategy to relieve symptoms of postpartum sciatica. © 2018 by the American College of Nurse-Midwives.

Ear Acupuncture in European Traditional Medicine

Directory of Open Access Journals (Sweden)

Luigi Gori

2007-01-01

Full Text Available Auricular acupuncture is a diagnostic and treatment system based on normalizing the body's dysfunction through stimulation of definite points on the ear. Rudimentary forms of acupuncture which probably arose during the Stone Age have survived in many parts of the world right down to present day. It was used in the ancient Egypt, Rome, Greece and all the Mediterranean area. It is a microacupuncture technique similar to reflexology, and was first described in France in 1950 by Paul Nogier who is considered the Father of modern ear acupuncture. It was speculated that the technique works because groups of pluripotent cells contain information from the whole organism and create regional organization centers representing different parts of the body. Nevertheless stimulation of a reflex point in the ear seems relieve symptoms of distant pathologies. Modern research is confirming the efficacy of ear acupuncture for analgesia and anxiety related disease, while tobacco dependence and other substance abuse still need confirmation. Actually main methodological problems with auricular acupuncture are that exist too many maps with little agreement regarding point location in the ear, and that the correspondence or reflex systems does not correlated with modern knowledge of anatomy and physiology.

The mechanisms of acupuncture are poorly understood. In consequence, numerous investigators have conducted clinical trials to test the efficacy of acupuncture in various conditions. We have used PubMed database system to evaluate the number of publications in acupuncture and nuclear medicine procedures in the period from 1964 to 2007, using the keywords: 'nuclear medicine and acupuncture', 'SPECT and acupuncture, 'PET and acupuncture', 'scintigraphy and acupuncture, 'radionuclide and acupuncture', 'radiopharmaceutical and acupuncture', 'radioisotope and acupuncture' and 99m Tc and acupuncture'. Some papers published in English language were selected and a short review is presented The analysis of the number of publications shows that when a method is well accepted by the scientific community, as the methods used in nuclear medicine, the interest in the development of research increases. Moreover, important findings are presented when the nuclear medicine image is used to evaluate the effect of the acupuncture. (author)

Electro-oxidation of methanol on copper in alkaline solution

International Nuclear Information System (INIS)

Heli, H.; Jafarian, M.; Mahjani, M.G.; Gobal, F.

2004-01-01

The electro-oxidation of methanol on copper in alkaline solutions has been studied by the methods of cyclic voltammetry, quasi-steady state polarization and chronoamperometry. It has been found that in the course of an anodic potential sweep the electro-oxidation of methanol follows the formation of Cu III and is catalysed by this species through a mediated electron transfer mechanism. The reaction also continues in the early stages of the reversed cycle until it is stopped by the prohibitively negative potentials. The process is diffusion controlled and the current-time responses follow Cottrellian behavior. The rate constants, turnover frequency, anodic transfer coefficient and the apparent activation energy of the electro-oxidation reaction are reported

By focusing on the endorphinergic system and its acclaimed role for exercise-induced antinociception and mood enhancement, we like to emphasize the unique potential of ligand PET applied to human athletes for uncovering the neurochemistry of exercise-induced psychophysiological phenomena. Compared with conventional approaches, in particular quantification of plasma beta-endorphin levels under exercise challenges, which are reviewed in this article, studying opioidergic effects directly in the central nervous system (CNS with PET and relating opioidergic binding changes to neuropsychological assessments, provides a more refined and promising experimental strategy. Although a vast literature dating back to the 1980s of the last century has been able to reproducibly demonstrate peripheral increases of beta-endorphin levels after various exercise challenges, so far, these studies have failed to establish robust links between peripheral beta-endorphin levels and centrally mediated behavioral effects, ie, modulation of mood and/or pain perception. As the quantitative relation between endorphins in the peripheral blood and the CNS remains unknown, the question arises, to what

The history of acupuncture in Ontario, Canada was traced, and the current status as welI as the prospection were introduced in this paper. Statistics showed that the history of acupuncture in Ontario started in the 1880s, and it was only popular in China Town and Chinese community. In the 1970s, it gradually merged into the mainstream of the society, and entered into a growing period. With the tide of Chinese immigration in the 1980s and 1990s, acupuncture matured rapidly. In 2006, the "Traditional Chinese Medicine Act" was passed in Ontario, it was considered as a milestone in the history of acupuncture. At present, just like the other 23 health care professions, acupuncture has already be included into the legislation system, and become a component of Ontario's health care system. At the same time, the law and regulation may also promote the establishment of "pure Chinese Medicine" in Ontario.

Functional dyspepsia (FD) is a common disease without an established optimal treatment. To determine (i) the effect of acupuncture in relieving FD symptoms and improving life quality; (ii) the effect difference between acupoint and non-acupoint; and (iii) the effect difference among different acupoints. A total of 712 eligible patients were included and randomly assigned to six groups (Group A: specific acupoints of the stomach meridian; Group B: non-specific acupoints of the stomach meridian; Group C: specific acupoints of alarm and transport points; Group D: specific acupoints of the gallbladder meridian; Group E: sham acupuncture of non-acupoints; and Group F: itopride). A treatment period of 4 weeks (continuous five sessions per week), and a follow-up period of 12 weeks were arranged. The outcomes were the (i) patients' response, (ii) symptoms improvement measured using the Symptom Index of Dyspepsia and (iii) quality-of-life improvement based on Nepean Dyspepsia Index. All groups had an improvement in dyspepsia symptoms and the QoL at the end of treatment, and the improvement was sustained for 4 weeks and 12 weeks. The overall response rate was significantly higher in acupuncture group A (70.69%), and lower in sham acupuncture group (34.75%), compared with itopride and other acupuncture groups. Similarly, the difference in symptoms and QoL improvement was significant between group A and the other acupuncture groups. Acupuncture is effective in the treatment of functional dyspepsia, and is superior to non-acupoint puncture. The benefit of acupuncture relies on acupoint specificity. © 2012 Blackwell Publishing Ltd.

2009-12-01

Full Text Available Abstract Background Dry eye is usually managed by conventional medical interventions such as artificial tears, anti-inflammatory drugs and surgical treatment. However, since dry eye is one of the most frequent ophthalmologic disorders, safer and more effective methods for its treatment are necessary, especially for vulnerable patients. Acupuncture has been widely used to treat patients with dry eye. Our aim is to evaluate the effectiveness and safety of acupuncture for this condition. Methods/Design A randomised, patient-assessor blinded, sham (non-acupuncture point, shallow acupuncture controlled study was established. Participants allocated to verum acupuncture and sham acupuncture groups will be treated three times weekly for three weeks for a total of nine sessions per participant. Seventeen points (GV23; bilateral BL2, GB4, TE23, Ex1 (Taiyang, ST1 and GB20; and left SP3, LU9, LU10 and HT8 for men, right for women have been selected for the verum acupuncture; for the sham acupuncture, points have been selected that do not coincide with a classical acupuncture point and that are located close to the verum points, except in the case of the rim of the eye. Ocular surface disease index, tear film breakup time, the Schirmer I test, medication quantification scale and general assessment of improvement will be used as outcome variables for evaluating the effectiveness of acupuncture. Safety will also be assessed at every visit. Primary and secondary outcomes will be assessed four weeks after screening. All statistical analyses will be performed using analysis of covariance. Discussion The results of this trial will be used as a basis for clarifying the efficacy of acupuncture for dry eye. Trial registration ClinicalTrials.gov NCT00969280.

Does the effect of acupuncture depend on needling sensation and manipulation?

Choi, Yu-Jin; Lee, Jae-Eun; Moon, Won-Kyung; Cho, Seung-Hun

2013-06-01

Acupuncture sensation and manipulation have been considered to be an important component of acupuncture in traditional Asian medicine. However, there has been limited research as to whether acupuncture sensation is associated with therapeutic benefit. This study investigated the relationship between acupuncture sensation and analgesic effect according to acupuncture manipulation. Fifty-three healthy volunteers received three different forms of acupuncture in a single-blinded crossover design: superficial needling (0.3 cm), deep needling (2 cm) and needling with bi-directional rotation. The effects of acupuncture were evaluated by using the pressure pain threshold. Acupuncture sensation measurement was done in two ways. Both total acupuncture sensation and increase of the pressure pain threshold were maximum in needling with rotation, followed by deep needling and superficial needling. Repeated-measure analysis of variance (ANOVA) analysis was carried out to assess whether there was a significant difference; both showed significant difference (p = 0.000, 0.003). A paired sample t-test was carried out, which revealed that needling with rotation showed significant difference from both superficial needling and deep needling. Further, the correlation between the total acupuncture sensation and changes in pressure pain threshold were calculated using Pearson correlation; there was a significant correlation (p = 0.002, p = 0.013). Acupuncture sensation and pressure pain threshold increase according to the depth and rotation of acupuncture. Especially, both display significant increase with needle rotation. Further, there is a significant correlation between acupuncture needling sensation and increase in pressure pain threshold. It seems that needle rotation and acupuncture sensation play an important role in verifying the effect of acupuncture. Copyright © 2013 Elsevier Ltd. All rights reserved.

Acupuncture is an ancient practice that is currently used to treat disorders ranging from osteoarthritis to cardiomyopathy. Acupuncture involves the insertion of thin, sterile needles into defined acupuncture points that stimulate physiologic processes through neural signaling. Numerous scientific studies have proven the benefits of acupuncture, and given this scientific support, we hypothesized that acupuncture could benefit the nonhuman primates at our facility. As our chimpanzee colony ages, we are observing an increase in osteoarthritis and have focused our initial acupuncture treatments on this condition. We successfully trained 3 chimpanzees, by using positive-reinforcement training techniques, to voluntarily participate in acupuncture treatments for stifle osteoarthritis. We used 3 acupuncture points that correlate with alleviation of stifle pain and inflammation in humans. A mobility scoring system was used to assess improvements in mobility as a function of the acupuncture treatments. The 2 chimpanzees with the most severe osteoarthritis showed significant improvement in mobility after acupuncture treatments. Acupuncture therapy not only resulted in improved mobility, but the training sessions also served as enrichment for the animals, as demonstrated by their voluntary participation in the training and treatment sessions. Acupuncture is an innovative treatment technique that our data show to be safe, inexpensive, and, most importantly, effective for chimpanzees. PMID:23849446

Gaillard, R C; Bachman, M; Rochat, T; Egger, D; de Haller, R; Junod, A F

1986-01-01

Concentrations of endogenous opioid peptides in the plasma are increased during exercise and these substances have been implicated in the pathogenesis of asthma induced by chloropropramide and alcohol in diabetic patients. This work was undertaken to determine whether exercise induced asthma might be mediated by endogenous opioids. Plasma beta endorphin, met-enkephalin, and adrenocorticotrophic hormone (ACTH) concentrations were measured in five asthmatic patients and five normal volunteers breathing cold air during exercise. In four of the patients the effect of an infusion of naloxone on FEV1 was also measured during exercise induced asthma. Exercise produced acute bronchoconstriction in all asthmatics, characterised by a fall in FEV1; whereas no change occurred in normal subjects. There was no difference in plasma met-enkephalin, beta endorphin, and ACTH concentration between the two groups. Infusion of naloxone neither prevented nor worsened exercise induced asthma. These data suggest that endogenous opioids probably do not play a part in the development of exercise induced asthma. PMID:2944240

Background Acupuncture is often used for migraine prevention but its effectiveness is still controversial. We present an update of our Cochrane review from 2009. Objectives To investigate whether acupuncture is a) more effective than no prophylactic treatment/routine care only; b) more effective than sham (placebo) acupuncture; and c) as effective as prophylactic treatment with drugs in reducing headache frequency in adults with episodic migraine. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL: 2016, issue 1); MEDLINE (via Ovid, 2008 to January 2016); Ovid EMBASE (2008 to January 2016); and Ovid AMED (1985 to January 2016). We checked PubMed for recent publications to April 2016. We searched the World Health Organization (WHO) Clinical Trials Registry Platform to February 2016 for ongoing and unpublished trials. Selection criteria We included randomized trials at least eight weeks in duration that compared an acupuncture intervention with a no-acupuncture control (no prophylactic treatment or routine care only), a sham-acupuncture intervention, or prophylactic drug in participants with episodic migraine. Data collection and analysis Two reviewers checked eligibility; extracted information on participants, interventions, methods and results, and assessed risk of bias and quality of the acupuncture intervention. The primary outcome was migraine frequency (preferably migraine days, attacks or headache days if migraine days not measured/reported) after treatment and at follow-up. The secondary outcome was response (at least 50% frequency reduction). Safety outcomes were number of participants dropping out due to adverse effects and number of participants reporting at least one adverse effect. We calculated pooled effect size estimates using a fixed-effect model. We assessed the evidence using GRADE and created ’Summary of findings’ tables. Main results Twenty-two trials including 4985 participants in total (median 71, range

Abstract Acupuncture is a promising therapy for relieving symptoms in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which affects >15% of adult men worldwide. The aim of the study was to assess the effects and safety of the use of acupuncture for CP/CPPS. MEDLINE, EMBASE, CENTRAL, Web of Science, CBM, CNKI, Wang-Fang Database, JCRM, and CiNii were searched from their inception through 30 November 2015. Grey literature databases and websites were also searched. No language limits were applied. Only randomized controlled trials (RCTs) with CP/CPPS treated by acupuncture were included. Two reviewers extracted data and assessed the risk of bias of RCTs using the Cochrane Risk of Bias Tools, respectively. Seven trials were included, involving 471 participants. The result of meta-analysis indicated that compared with sham acupuncture (MD: −6.09 [95%CI: −8.12 to −5.68]) and medicine (Levofloxacinand, Ibuprofen, and Tamsulosin) (MD: −4.57 [95%CI: −7.58 to −1.56]), acupuncture was more effective at decreasing the total NIH-CPSI score. Real acupuncture was superior to sham acupuncture in improving symptoms (pain, voiding) and quality of life (Qof) domain subscores. Compared to sham acupuncture and medicine, acupuncture appears to be more effective at improving the global assessment. Two trials found that there is no significant difference between acupuncture and sham acupuncture in decreasing the IPSS score. Acupuncture failed to show more favorable effects in improving both symptoms and the Qof domain compared with medicine. Overall, current evidence supports acupuncture as an effective treatment for CP/CPPS-induced symptoms, particularly in relieving pain. Based on the meta-analysis, acupuncture is superior to sham acupuncture in improving symptoms and Qof. Acupuncture might be similar to medicine (Levofloxacinand, Ibuprofen, and Tamsulosin) in its long-term effects, but evidence was limited due to high ROB among included trials as well as

Previous trials on acupuncture in alcohol addiction were in outpatients and focused on relapse prevention. Rates of dropout were high and interpretation of results difficult. We compared auricular laser and needle acupuncture with sham laser stimulation in reducing the duration of alcohol withdrawal. Inpatients undergoing alcohol withdrawal were randomly allocated to laser acupuncture (n = 17), needle acupuncture (n = 15) or sham laser stimulation (n = 16). Attempts were made to blind patients, therapists and outcome assessors, but this was not feasible for needle acupuncture. The duration of withdrawal symptoms (as assessed using a nurse-rated scale) was the primary outcome; the duration of sedative prescription was the secondary outcome. Patients randomized to laser and sham laser had identical withdrawal symptom durations (median 4 days). Patients randomized to needle stimulation had a shorter duration of withdrawal symptoms (median 3 days; P = 0.019 versus sham intervention), and tended to have a shorter duration of sedative use, but these differences diminished after adjustment for baseline differences. The data from this pilot trial do not suggest a relevant benefit of auricular laser acupuncture for alcohol withdrawal. A larger trial including adequate sham interventions is needed, however, to reliably determine the effectiveness of any type of auricular acupuncture in this condition.

Acupuncture Anesthesia and Analgesia for Clinical Acute Pain in Japan

2008-01-01

Full Text Available Acupuncture anesthesia has been practiced in China since about 1960. In Japan, Hyodo reported 30 cases of acupuncture anesthesia in 1972. However, from around 1980, the direction of acupuncture investigations turned from anesthesia to analgesia. Acupuncture analgesia is presently considered a way to activate the body's endogenous analgesic system. Recently, with the rise of acupuncture as one of the most well known CAM therapies, acupuncture or moxibustion treatment has been reported for both acute and chronic pain. Even so, few clinical reports and original articles have been reported in Japan. This review illustrates how acupuncture is being used in Japan for acute pain such as surgical operations, post- operative pain (POP, neuropathic pain, pain associated with teeth extractions and after the extraction of impacted wisdom teeth.

Full Text Available Abstract Background Since transport evokes physiological adjustments that include endocrine responses, the objective of this study was to examine the responses of circulating β-endorphin, adrenocorticotrophic hormone (ACTH and cortisol levels to transport stress in stallions. Methods Forty-two healthy Thoroughbred and crossbred stallions were studied before and after road transport over distances of 100, 200 and 300 km. Blood samples were collected from the jugular vein: first in a single box immediately before loading (pre-samples, then immediately after transport and unloading on arrival at the breeding stations (post-samples. Results An increase in circulating β-endorphin levels after transport of 100 km (P P P P P > 0.05 between horses of different ages and different breeds were observed for β-endorphin, ACTH and cortisol levels. Conclusion The results obtained for short term transportation of stallions showed a very strong reaction of the adrenocortical system. The lack of response of β-endorphin after transport of 200–300 km and of ACTH after transport of 300 km seems to suggest a soothing effect of negative feedback of ACTH and cortisol levels.

Chunxiao Wu

2014-01-01

Full Text Available Functional magnetic resonance imaging (fMRI has been shown to detect the specificity of acupuncture points, as proved by numerous studies. In this study, resting-state fMRI was used to observe brain areas activated by acupuncture at the Taichong (LR3 acupoint. A total of 15 healthy subjects received brain resting-state fMRI before acupuncture and after sham and true acupuncture, respectively, at LR3. Image data processing was performed using Data Processing Assistant for Resting-State fMRI and REST software. The combination of amplitude of low-frequency fluctuation (ALFF and regional homogeneity (ReHo was used to analyze the changes in brain function during sham and true acupuncture. Acupuncture at LR3 can specifically activate or deactivate brain areas related to vision, movement, sensation, emotion, and analgesia. The specific alterations in the anterior cingulate gyrus, thalamus, and cerebellar posterior lobe have a crucial effect and provide a valuable reference. Sham acupuncture has a certain effect on psychological processes and does not affect brain areas related to function.

Conclusion: Beliefs and values are an underrepresented, yet extremely important aspect of philosophical concepts influencing acupuncture practice in Japan. Uniquely Japanese beliefs and values that do not rely on a commitment to any spiritual or religious affiliations or proprietary knowledge of traditional or biomedicine may be successfully exported from Japan to advance acupuncture education, research and practice in international contexts.

Bilateral tension pneumothorax after acupuncture.

Mohammad, Nurashikin

2018-04-19

Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung. She had type 1 respiratory failure. Urgent chest radiograph confirmed bilateral pneumothorax which was more severe on the left with tension pneumothorax and mediastinal shift. Chest tubes were inserted bilaterally after failed needle aspiration attempts. Subsequently, the pneumothoraces resolved, and she was discharged well. The bilateral pneumothoraces caused by acupuncture were curable but could have been potentially fatal if diagnosis was delayed. This case report adds to the limited current literature on the complications of acupuncture leading to bilateral pneumothoraces. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

2015-12-01

As one of the important founders of GAO's acupuncture academic school in YanZhao area, Professor GAO Yuchun 's experience of acupuncture for headache is summarized in this paper. In the opinion of Professor GAO, the treatment of headache should focus on eliminating evil and relieving pain, and the syndrome differentiation should be based on meridian differentiation, especially on three yang meridians of foot as well as liver meridian and kidney meridian. In the acupoint prescription, attention should be placed on strengthening the spleen and stomach. The midnight-midday ebb flow acupuncture is advocated. The combination between acupuncture order and movement of qi is emphasized. In the manipulation, the role of pressing hand, the stimulation during reinforcing and reducing methods, and needle-retention time are important. The breathing reinforcing and reducing method of acupuncture are also advocated.

Acupuncture as anticancer treatment?

Directory of Open Access Journals (Sweden)

Paulina Frączek

2017-01-01

Full Text Available The mystery of Traditional Chinese Medicine has been attracting people for years. Acupuncture, ranked among the most common services of Complementary and Alternative Medicine, has recently gained a lot of interest in the scientific world. Contemporary researchers have been continuously trying to shed light on its possible mechanism of action in human organism. Numerous studies pertaining to acupuncture’s application in cancer symptoms or treatment-related side effects management have already been published. Moreover, since the modern idea of acupuncture’s immunomodulating effect seems to be promising, scientists have propounded a concept of its potential application as part of direct anti-tumor therapy. In our previous study we summarized possible use of acupuncture in management of cancer symptoms and treatment-related ailments, such as chemotherapy-induced nausea and vomiting, pain, xerostomia, vasomotor symptoms, neutropenia, fatigue, anxiety, insomnia, lymphoedema after mastectomy and peripheral neuropathy. This article reviews the studies concerning acupuncture as a possible tool in modern anticancer treatment.

Ankle sprain is one of the most frequently encountered musculoskeletal injuries; however, the efficacy of acupuncture in treating ankle sprains remains uncertain. We therefore performed a systematic review to evaluate the evidence regarding acupuncture for ankle sprains. We searched 15 data sources and two trial registries up to February 2012. Randomized controlled trials of acupuncture were included if they involved patients with ankle sprains and reported outcomes of symptom improvement, including pain. A Cochrane risk of bias assessment tool was used. Risk ratio (RR) or mean difference (MD) was calculated with 95% confidence intervals (CIs) in a random effects model. Subgroup analyses were performed based on acupuncture type, grade of sprain, and control type. Sensitivity analyses were also performed with respect to risk of bias, sample size, and outcomes reported. Seventeen trials involving 1820 participants were included. Trial quality was generally poor, with just three reporting adequate methods of randomization and only one a method of allocation concealment. Significantly more participants in acupuncture groups reported global symptom improvement compared with no acupuncture groups (RR of symptoms persisting with acupuncture = 0.56, 95% CI 0.42-0.77). However, this is probably an overestimate due to the heterogeneity (I2 = 51%) and high risk of bias of the included studies. Acupuncture as an add-on treatment also improved global symptoms compared with other treatments only, without significant variability (RR 0.61, 95% CI 0.51-0.73, I2 = 1%). The benefit of acupuncture remained significant when the analysis was limited to two studies with a low risk of bias. Acupuncture was more effective than various controls in relieving pain, facilitating return to normal activity, and promoting quality of life, but these analyses were based on only a small number of studies. Acupuncture did not appear to be associated with adverse events. Given

The relation between quality of clinical trials and acupuncture efficacy

Full Text Available Introduction: Clinical trials of acupuncture not always have concordant results, mostly due to their great heterogeneity. Two indexes have been developed to analyze the quality of acupuncture trials. This study hypothesizes that, the more adequate the intervention and the control techniques, the more efficacious the acupuncture. Methods: Both indexes were applied to 27 randomized clinical trials comparing acupuncture to placebo. Results were compared by using the Mann-Whitney test. Results: Studies favorable to acupuncture had a intervention score’s median of 11.5; for the unfavorable ones, it was 7, p: 0.0017. Articles with and without statistically significant differences, though, had the same median for their scores in the control index: 6. Discussion: There is a positive relation between a better score for acupuncture technique and a statistically significant difference between acupuncture and interventional control. However, due to the little heterogeneity in the degree of physiological effect from each article, the control index had no statistical significance. Conclusion: This study established that, among acupuncture RCT controlled by placebo or sham of moderate physiological effect, the adequacy of the technique is more important than the adequacy of control in establishing a statistically significant difference between acupuncture and interventional control.

Acupuncture treatment is different from treatment of materia medica. However, syndrome differentiation system of internal medicine is adopted all the time for the present acupuncture textbooks. It is held that the characteristics of acupuncture can not be fully reflexed, and advantages of acupuncture can not be brought into full play. Therefore, it's urgent to build up a modem theory on acupuncture treatment which is fit for the clinical practice of acupuncture and can give a better play for the treatment of acupuncture. A clear target is one of the characteristics of acupuncture treatment. And it is based on the understanding of the location of disease, therefore, disease differentiation is held as the basis of acupuncture treatment. The aim of meridian differentiation is to select distal effective points on the base of diseases differentiation, which is also taken as the characteristics of acupuncture treatment. Syndrome differentiation is a process of understanding the general pathological states of the human body, it is an important process to enhance the therapeutic effect of acupuncture. Thus, the key point for establishing the modern acupuncture theory is clarifying the values of disease differentiation, meridian differentiation and syndrome differentiation.

Can a science-based definition of acupuncture improve clinical outcomes?

Science.gov (United States)

Priebe, Ted; Stumpf, Steven H; Zalunardo, Rod

2017-05-01

Research on acupuncture has been muddled by attempts to bridge the ancient with the modern. Barriers to effectiveness research are reflected in recurring conflicts that include disagreement on use of the most basic terms, lack of standard intervention controls, and the absence of functional measures for assessing treatment effect. Acupuncture research has stalled at the "placebo barrier" wherein acupuncture is "no better than placebo." The most widely recognized comparative effectiveness research in acupuncture does not compare acupuncture treatment protocols within groups, thereby, mutating large scale effectiveness studies into large scale efficacy trials. Too often research in acupuncture attempts to tie outcomes to traditional belief systems thereby limiting usefulness of the research. The acupuncture research paradigm needs to focus more closely on a scientific definition of treatments and outcomes that compare protocols in terms of prevalent clinical issues such as relative effectiveness for treating pain.

Research advances in treatment of neurological and psychological diseases by acupuncture at the Acupuncture Meridian Science Research Center

Bombi Lee

2014-06-01

Full Text Available Acupuncture is an ancient therapeutic intervention that can be traced back at least 2100 years and is emerging worldwide as one of the most widely used therapies in the field of complementary and alternative medicine. Due to limitations associated with Western medicine's focus on the treatment of diseases rather than on their causes, interests are shifting to complementary and alternative medicines. The Acupuncture and Meridian Science Research Center (AMSRC was established in 2005 to elucidate the neurophysiological mechanisms of acupuncture for neurological diseases based on multidisciplinary research supported by the Korean Ministry of Science and Technology. In the AMSRC, resultant research articles have shown that acupuncture can improve neurological and psychological problems, including Parkinson's disease, pain, and depression, in animal models. Basic research studies suggest its effectiveness in treating various problems such as depression, drug addiction, epilepsy, ischemia, dementia, Parkinson's disease, and pain. We strongly believe that these effects, evident from the AMSRC research results, can play leading roles in the use of acupuncture for treating neurological diseases, based on collaboration among various academic fields such as neurophysiology, molecular genetics, and traditional Korean medicine.

Through the collection of Practice of acupuncture and moxibustion written by CHEN Jingwen, the acupuncture master in the Republic of China, the academic characteristics on acupuncture and moxibusiton were analyzed. The literature comparison method was adopted to compare the works of LUO Zhaoju, ZENG Tianzhi and LI Wenxian, etc. at the same period. It was discovered that CHEN Jingwen was the medical master who systematicly brought up the theory of acupoint properties earlier in the modern times. Classifying drugs based on acupoints was his academic feature. Additionally, the compatibility therapy of Chinese medicine was introduced to explain the essential ideas on the acupoints combination. The treatment was determined on the basis of zangxiang theory and the reinforcing and reducing therapy of acupuncture was emphasized in the determination of treatment and prescription. CHEN Jingwen's theory of acupoint property had been stressed and spread among the medical scholars in the Republic of China and he had made the beneficial exploration for the development of modern acupuncture and moxibustion therapy.

Objective Evidence-based treatment guidelines have been unable to provide evidence-based guidance on the effects of acupuncture for irritable bowel syndrome (IBS) because the only previous systematic review included only small, heterogeneous and methodologically unsound trials. We conducted a new systematic review and meta-analysis of randomized controlled trials (RCTs) to estimate the effects of acupuncture for treating IBS. Methods MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE, Cumulative Index to Nursing and Allied Health, and the Chinese databases Sino-Med, CNKI, and VIP were searched through November 2011. Eligible RCTs compared acupuncture with sham acupuncture, other active treatments, or no (specific) treatment, and evaluated acupuncture as an adjuvant to another treatment. Our outcomes were overall IBS symptom severity and health-related quality of life. Dichotomous data were pooled to provide a relative risk (RR) of substantial improvement after treatment, and continuous data were pooled to provide a standardized mean difference (SMD) in post-treatment scores between groups. Results Seventeen RCTs (N=1806) were included. We found no evidence of an improvement with acupuncture relative to sham acupuncture on symptom severity (SMD = −0.11, 95% confidence interval: −0.35 to 0.13; 4 RCTs) or quality of life (SMD = −0.03, −0.27 to 0.22; 3 RCTs). Because of the homogeneity of the results of the sham-controlled trials, results were unaffected by restriction to the 4 sham-controlled RCTs that used adequate randomization, blinding, and had few withdrawals/drop-outs. Among RCTs that did not use a placebo control, acupuncture was more effective than pharmacological therapy (RR of symptom improvement=1.28, 1.12 to 1.45; 5 RCTs) and no (specific) treatment (RR = 2.11, 1.18 to 3.79; 2 RCTs). There was no difference between acupuncture and Bifidobacterium (RR = 1.07, 0.90 to 1.27; 2 RCTs) or between acupuncture and psychotherapy (RR=1.05, 0

Relationships Between Self-Injurious Behaviors, Pain Reactivity, and β-Endorphin in Children and Adolescents With Autism.

Autism and certain associated behaviors including self-injurious behaviors (SIB) and atypical pain reactivity have been hypothesized to result from excessive opioid activity. The objective of this study was to examine the relationships between SIB, pain reactivity, and β-endorphin levels in autism. Study participants were recruited between 2007 and 2012 from day care centers and included 74 children and adolescents diagnosed with autism (according to DSM-IV-TR, ICD-10, and CFTMEA) and intellectual disability. Behavioral pain reactivity and SIB were assessed in 3 observational situations (parents at home, 2 caregivers at day care center, a nurse and child psychiatrist during blood drawing) using validated quantitative and qualitative scales. Plasma β-endorphin concentrations were measured in 57 participants using 2 different immunoassay methods. A high proportion of individuals with autism displayed SIB (50.0% and 70.3% according to parental and caregiver observation, respectively). The most frequent types of SIB were head banging and hand biting. An absence or decrease of overall behavioral pain reactivity was observed in 68.6% and 34.2% of individuals with autism according to parental and caregiver observation, respectively. Those individuals with hyporeactivity to daily life accidental painful stimuli displayed higher rates of self-biting (P < .01, parental evaluation). No significant correlations were observed between β-endorphin level and SIB or pain reactivity assessed in any of the 3 observational situations. The absence of any observed relationships between β-endorphin level and SIB or pain reactivity and the conflicting results of prior opioid studies in autism tend to undermine support for the opioid theory of autism. New perspectives are discussed regarding the relationships found in this study between SIB and hyporeactivity to pain. © Copyright 2018 Physicians Postgraduate Press, Inc.

Purpose: To examine whether ionizing radiation enhances the migratory and invasive abilities of cancer cells through transforming growth factor (TGF-{beta})-mediated epithelial-mesenchymal transition (EMT). Methods and Materials: Six cancer cell lines originating from different human organs were irradiated by {sup 60}Co {gamma}-ray at a total dose of 2 Gy, and the changes associated with EMT, including morphology, EMT markers, migration and invasion, were observed by microscope, Western blot, immunofluorescence, scratch assay, and transwell chamber assay, respectively. Then the protein levels of TGF-{beta} in these cancer cells were detected by enzyme-linked immunosorbent assay, and the role of TGF-{beta} signaling pathway in the effect of ionizing radiation on EMT was investigate by using the specific inhibitor SB431542. Results: After irradiation with {gamma}-ray at a total dose of 2 Gy, cancer cells presented the mesenchymal phenotype, and compared with the sham-irradiation group the expression of epithelial markers was decreased and of mesenchymal markers was increased, the migratory and invasive capabilities were strengthened, and the protein levels of TGF-{beta} were enhanced. Furthermore, events associated with EMT induced by IR in A549 could be reversed through inhibition of TGF-{beta} signaling. Conclusions: These results suggest that EMT mediated by TGF-{beta} plays a critical role in IR-induced enhancing of migratory and invasive capabilities in cancer cells.

An acute ankle sprain is a sudden-onset injury of one or more of the ankle ligaments. It is one of the most common musculoskeletal injuries in the general population as well as in athletes. In some countries, such as China and Korea, acupuncture is frequently used in the treatment of ankle sprains, either as a single treatment or a secondary intervention accompanied by standard medical treatment. To assess the effects (benefits and harms) of acupuncture for the treatment of ankle sprains in adults. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (May 2013), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2013, Issue 4), MEDLINE (1948 to May week 2 2013), EMBASE (1980 to May week 2 2013), China National Knowledge Infrastructure databases (1994 to August week 4 2013), the Cumulative Index to Nursing and Allied Health Literature (1937 to May 2013), the Allied and Complementary Medicine Database (1985 to May 2013), Science Links Japan (1996 to August week 4 2013), several Korean medical databases (August week 4 2013), the World Health Organization International Clinical Trials Registry Platform (August week 4 2013), the bibliographic references of included trials and conference proceedings. We included randomised and quasi-randomised controlled trials involving adults with acute ankle sprains. We included all types of acupuncture practices, such as needle acupuncture, electroacupuncture, laser acupuncture, pharmacoacupuncture, non-penetrating acupuncture point stimulation (e.g. acupressure and magnets) and moxibustion. Acupuncture could be compared with control (no treatment or placebo) or another standard non-surgical intervention. Two review authors independently screened the search results, assessed trial eligibility, assessed risk of bias and extracted data from the included trials. We calculated risk ratios (RRs) for dichotomous outcomes and mean differences for continuous outcomes. We conducted meta

The philosophical ontology analysis was used in this study to explore the self-factors related to the cultural loss of modern acupuncture, and to establish the theoretical constructs and the clinical model for the cultural return. It is indicated that the most important factors related to the cultural loss of modern acupuncture are the separation of technical characteristics and cultural connotations and the diversion of modern techniques away from classical acupuncture. An effective way of the cultural return is to build a harmonious theoretical and clinical model to develop acupuncture. Based on the foundation of acupuncture from its own culture roots, the traditional sense and cultural values should be enhanced to facilitate the cultural return of acupuncture in theory and clinical practice.

Acupuncture is covered under the Accident Compensation (Liability to Pay or Contribute to Cost of Treatment) Regulations 2003, and is therefore eligible for Accident Compensation Corporation payments for the treatment of personal injuries. This study searched New Zealand acupuncturists' websites for therapeutic claims that may breach Section 58(1)(a) of the Medicines Act. A search of acupuncturists' websites shows that many claim to be able to treat a wide range of conditions, despite a lack of evidence showing the efficacy of acupuncture in the treatment of those conditions. Practitioners and owners of websites likely to be in breach of the Medicines Act include many committee members from acupuncture's professional bodies.

Bee venom acupuncture has been widely used in Oriental medicine with limited evidence of effectiveness. Most of the complications due to bee venom acupuncture are local or systemic allergic reactions. However, serious medical and neurological complications have also been reported. We herein describe the treatment of a 68-year-old woman who developed progressive quadriplegia 10 days after receiving multiple honeybee venom sting acupuncture treatments. The electrophysiological findings were consistent with Guillain-Barré syndrome (GBS). The temporal relationship between the development of GBS and honeybee venom sting acupuncture is suggestive of a cause-and-effect relationship, although the precise pathophysiology and causative components in honeybee venom need to be verified.
