Randomized single-blinded prospective comparison between ozone therapy and electroacupuncture for canine thoracolumbar disk disease.

Ozone therapy has been used to control pain in animals. Moreover, electroacupuncture (EA) has been effective in neurological recovery and pain control in dogs with thoracolumbar discopathy. EA was compared with Ozone applied at acupuncture points in dogs with signs of thoracolumbar disk disease. Chondrodystrophic mongrel dogs, with lesion scores between 1 and 4, were randomly divided into groups: EA (n = 13) - electroacupuncture at BL20, BL23, ST36, KID3 and BL60 and dry needle in lumbar Bai Hui, and OZO (n = 15) - paravertebral application of 3 mL ozone (20 µg / mL) at BL20, BL23, lumbar Bai Hui, ST36, and KID3/BL60, both groups with weekly applications. No significant differences were observed between groups in weekly blind pain assessments using a dynamic interactive visual analog scale, and neurological assessments using a numerical-functional scale. Both groups showed a progressive improvement in pain control and neurological condition, which was observed when comparing the group's EA and OZO in dogs with all lesion scores. The time of return to locomotion (days) of dogs scored 3 and 4, between groups EA (10.6 ± 5.4) and OZO (14.5 ± 15.7), had no significant differences. Ozone therapy was effective to control pain and motor rehabilitation and sensory functions of dogs with thoracolumbar discopathy signs, just as electroacupuncture. Ozone application was a quick and easy-to-handle treatment. Paravertebral and subcutaneous routes did not require anesthesia or other advanced imaging technology, besides being safe and effective.

Histopathological, immunohistochemical and biochemical evaluation of electroacupuncture treatment of nervus radialis and nervus ulnaris injuries in rabbits.

The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4 (Large Intestine Meridian-4, He Gu), LI-10 (Large Intestine Meridian-10, Shou San Li), LR-3 (Liver Meridian-3, Tai Chong), and ST-36 (Stomach Meridian-36, Zusanli) electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Decapitation was performed under general anesthesia at the end of electroacupuncture applications. After the euthanasia procedure, the samples obtained were evaluated for histopathological, immunohistochemical and biochemical parameters. In conclusion, degenerative foci in the treatment groups were found to be fewer than in the PC group whereas NGF and S-100 immunoreactivity were higher in the treatment groups than in the PC group. Whereas no statistically significant difference was observed between the treatment groups and the NC group in terms of oxidative stress factors, there was a statistically significant difference between the treatment groups and the PC group. In light of all these data, we have concluded that electroacupuncture is an effective treatment method for peripheral nerve injuries.

Antinociceptive, physiologic and biochemical effects of electroacupuncture combined with xylazine in hybrid goats.

OBJECTIVE: To elucidate the antinociceptive, physiologic and biochemical effects of electroacupuncture (EA) and xylazine in hybrid goats. STUDY DESIGN: Prospective experimental study. ANIMALS: A total of 30 female hybrid goats aged 1-2 years and weighing 25 ± 2.9 kg (mean ± standard deviation). METHODS: The goats were divided into five groups and administered xylazine (0.1 mg kg-1; group XYL.1), xylazine (0.3 mg kg-1; group XYL.3), EA (group EA), EA + xylazine (0.1 mg kg-1; group XYL.1-EA) and 0.9% saline (0.3 mL; control group CON). Nociceptive threshold and serum glucose concentration were measured at time 0 and at 15, 30, 45, 60 minutes and 24 hours after treatment. Nociceptive threshold was measured by passing potassium ions through the skin using potassium iontophoresis. Mean arterial pressure (MAP), heart rate (HR), respiratory frequency (fR) and rectal temperature (RT) were recorded at times 0 and at 5, 10, 15, 20, 30, 45, 60 minutes and 24 hours. Repeated-measures analyses were performed for each response variable; p < 0.05 was considered significant for all analyses. RESULTS: Antinociceptive effects in groups XYL.1 and XYL.3 were increased significantly at 15-60 minutes compared with group CON. Antinociceptive effect was higher in group XYL.1-EA than groups XYL.1 or EA at 15-60 minutes (p < 0.05). No significant difference in the nociceptive threshold was recorded in groups XYL.1-EA and XYL.3, except at 30 minutes. HR, MAP, fR, RT values were higher in group XYL.1-EA than in groups XYL.1 or XYL.3. Serum glucose concentration was higher in group XYL.3 at 15-60 minutes than in CON. CONCLUSIONS AND CLINICAL RELEVANCE: The XYL.1 and EA combination was effective for antinociception with minimum physiologic alteration, suggesting that the combination may be a new and effective strategy for pain relief during clinical procedures in goats.

Electroacupuncture anesthesia for laparotomy in goats.

Background: The objective of the study to evaluate the effect of electroacupuncture during laparotomy in goats. Aim: To study the abdominal anesthesia in goats by electroacupuncture using the physiological variables, vital parameters, hematological, biochemical, cortisol hormone, pain threshold, and wound healing for laparotomy in goats. Methods: Fifteen healthy adult bucks were used to receive electroacupuncture in 10 newly selected acupoints. The data (M ± SD) were assessed at intervals (0 minutes) before induction (control group), (5 minutes), (10 minutes), (15 minutes), and (20 minutes) during induction, (30 minutes), (45 minutes), and (60 minutes) throughout surgery and (24 hours) after surgery, cortisol levels in serum at (0), (24 hours), and (72 hours) throughout laparotomy. Results: The goats of the study showed improvement in the rates of eyelid closure, head, and neck relaxation, rumen motility, and tympany which were graded into mild (+), moderate (++), and severe (+++) degrees. The respiratory rates, body temperatures, and capillary fill times were not significantly different. The total mean of hematocrit was (19.9 ± 2.68), the total mean of hemoglobin was (9.9 ± 0.94), the total mean of red blood cells was (7.9 ± 0.8), the total mean of platelets was (244,861.3 ± 138,444.8) and the total mean of SPO2 was (70.5 ± 4.6). ALT and AST showed no significance. The significant mean cortisol level was (2.6 ± 2.01) and the significant mean pain threshold level was (0.02 ± 0.03). The results proved that electroacupuncture had a lot of significant parameters. The wound healing was improved by early epithelization and immature granulation tissue (at 7 days). Thick keratinized epithelization and collagen deposition in the dermal tissue with enhanced angiogenesis (at 14 days). Mild restoration of skin and the dermal tissue was well-organized (at 21 days). Besides, well-formed scar tissue covering a highly cellular organized dermal tissue (at 28 days). Conclusions: Electroacupuncture had been considered a powerful anesthetic for abdominal surgery in goats. Moreover, wound healing proved excellent and better healing.

Analgesic efficacy of laser acupuncture and electroacupuncture in cats undergoing ovariohysterectomy.

The aim of this study was to compare the effects of laser acupuncture and electroacupuncture on postoperative pain and analgesic requirements in cats. In a prospective, randomized and blinded clinical study, thirty cats undergoing ovariohysterectomy were sedated with intramuscular (IM) ketamine (5 mg/kg), midazolam (0.5 mg/kg), and tramadol (2 mg/ kg). Before the induction of anesthesia, the animals were randomly distributed into three groups of ten cats each: LA: bilateral Stomach 36 (ST-36) and Spleen 6 (SP-6) acupoints were stimulated with an infrared laser; EA: bilateral ST-36 and SP-6 acupoints were stimulated with an electrical stimulus; Control: no acupuncture was applied. Postoperative analgesia was evaluated in the first 24 hr post-extubation using the Interactive Visual Analogue Scale and UNESP-Botucatu Multidimensional Composite Pain Scale. Rescue analgesia was provided with IM tramadol (2 mg/kg), and the pain scores were reassessed 30 min after the rescue intervention. If the analgesia remained insufficient, meloxicam (0.2 mg/kg IM, single dose) was administered. Data were analyzed using t-tests, the Mann-Whitney U test, and Friedman test. P<0.05 was considered significant. The pain scores did not significantly differ between the treatment groups at any time point (P>0.05). The prevalence of rescue analgesia was significantly higher in the Control group than in the LA and EA groups (P=0.033). Preoperative laser and electroacupuncture reduced the need for rescue analgesia during the first 24 hr after ovariohysterectomy.

EVALUATION OF ACUPUNCTURE POINTS GOVERNING VESSELS 1 AND 26 ON ANESTHETIC RECOVERY OF EASTERN BOX TURTLES ( TERRAPENE CAROLINA CAROLINA).

Intramuscular administration of anesthetic agents in chelonians may result in a prolonged (≥1 hr) return of spontaneous movement and breathing, which increases the probability for peri- and postoperative complications. The acupuncture point governing vessel (GV)-26 has been demonstrated to reduce anesthetic recovery times from inhalant anesthesia in other species. In this study, 30 eastern box turtles (EBT; Terrapene carolina carolina), presented to the Turtle Rescue Team at North Carolina State University's College of Veterinary Medicine for treatment of aural abscess, were divided into four groups: control (no treatment); GV-26 acupuncture; GV-1 and GV-26 acupuncture; or GV-1 and GV-26 electroacupuncture. Turtles receiving either GV-1 and GV-26 acupuncture or GV-1 and GV-26 electroacupuncture had a significantly reduced time to return of voluntary movement ( P = 0.012 and P = 0.006, respectively), a significantly reduced time to response of limb extension ( P = 0.03 and P < 0.001, respectively), and a significantly reduced time to anesthetic recovery ( P < 0.05 and P < 0.01, respectively). Therefore, the use of either GV-1 and GV-26 acupuncture or GV-1 and GV-26 electroacupuncture produces significant reductions in anesthetic recovery time in EBTs that have received injectable anesthetics.

Analgesic and physiological effect of electroacupuncture combined with epidural lidocaine in goats.

OBJECTIVE: To investigate physiological and antinociceptive effects of electroacupuncture (EA) with lidocaine epidural nerve block in goats. STUDY DESIGN: Prospective experimental trial. ANIMALS: Forty-eight hybrid male goats weighing 27 ± 2 kg. METHODS: The goats were randomly assigned to six groups: L2.2, epidural lidocaine (2.2 mg kg-1); L4.4, epidural lidocaine (4.4 mg kg-1); EA; EA-L1.1, EA with epidural lidocaine (1.1 mg kg-1); EA-L2.2, EA with epidural lidocaine (2.2 mg kg-1); and EA-L4.4, EA with epidural lidocaine (4.4 mg kg-1). EA was administered for 120 minutes. Epidural lidocaine was administered 25 minutes after EA started. Nociceptive thresholds of flank and thigh regions, abdominal muscle tone, mean arterial pressure (MAP), heart rate (HR), respiratory frequency (fR) and rectal temperature were recorded at 30, 60, 90, 120, 150 and 180 minutes. RESULTS: Lidocaine dose-dependently increased nociceptive thresholds. There were no differences in nociceptive thresholds between L4.4 and EA from 30 to 120 minutes. The threshold in EA-L2.2 was lower than in EA-L4.4 from 30 to 120 minutes, but higher than in EA-L1.1 from 30 to 150 minutes or in L4.4 from 30 to 180 minutes. The abdominal muscle tone in EA-L2.2 was higher at 30 minutes, but lower at 90 and 120 minutes than at 0 minutes. There were no differences in muscle tone between L4.4 and L2.2 or EA-L4.4, and between any two of the three EA-lidocaine groups from 0 to 180 minutes. The fR and HR decreased in L4.4 at 60 and 90 minutes compared with 0 minutes. No differences in fR, HR, MAP and temperature among the groups occurred from 30 to 180 minutes. CONCLUSIONS AND CLINICAL RELEVANCE: EA combined with 2.2 mg kg-1 epidural lidocaine provides better antinociceptive effect than 4.4 mg kg-1 epidural lidocaine alone in goats. EA provided antinociception and allowed a decrease in epidural lidocaine dose.

Electroacupuncture improves gait locomotion, H-reflex and ventral root potentials of spinal compression injured rats.

This study explored the effect of electroacupuncture stimulation (EA) on alterations in the Hoffman reflex (H-reflex) response and gait locomotion provoked by spinal cord injury (SCI) in the rat. A compression lesion of the spinal cord was evoked by insufflating a Fogarty balloon located in the epidural space at the T8-9 spinal level of adult Wistar male rats (200-250 gr; n=60). In different groups of SCI rats, EA (frequencies: 2, 50 and 100Hz) was applied simultaneously to Huantiao (GB30), Yinmen (BL37), Jizhong (GV6) and Zhiyang (GV9) acupoints from the third post-injury day until the experimental session. At 1, 2, 3 and 4 post-injury weeks, the BBB scores of the SCI group of rats treated with EA at 50Hz showed a gradual but greater enhancement of locomotor activity than the other groups of rats. Unrestrained gait kinematic analysis of SCI rats treated with EA-50Hz stimulation showed a significant improvement in stride duration, length and speed (p<0.05), whereas a discrete recovery of gait locomotion was observed in the other groups of animals. After four post-injury weeks, the H-reflex amplitude and H-reflex/M wave amplitude ratio obtained in SCI rats had a noticeable enhancement (217%) compared to sham rats (n=10). Meanwhile, SCI rats treated with EA at 50Hz manifested a decreased facilitation of the H-reflex amplitude and H/M amplitude ratio (154%) and a reduced frequency-dependent amplitude depression of the H-reflex (66%). In addition, 50 Hz-EA treatment induced a recovery of the presynaptic depression of the Gs-VRP evoked by PBSt conditioning stimulation in the SCI rat (63.2±8.1%; n=9). In concordance with the latter, it could be suggested that 50 Hz-EA stimulation reduced the hyper-excitability of motoneurons and provokes a partial improvement of the locomotive performance and H reflex responses by a possible recovery of presynaptic mechanisms in the spinal cord of experimentally injured rats.

Eletroacupuntura na analgesia trans e pós-operatória de cadelas submetidas à ovariosalpingohisterectomia / Electroacupuncture in trans and postoperative analgesia in bitches submitted to ovariosalpingohisterectomy

Objetivou-se com este estudo avaliar o efeito analgésico trans e pós-operatório da eletroacupuntura em onda denso-dispersa e frequências 3 e 200Hz, nos pontos E44, R3 e BP4, compará-lo com a analgesia promovida pelos pontos BP6, E36 e VB 34, e pela morfina, em cadelas submetidas à ovariosalpingohisterectomia (OSH). Teve-se como hipótese que a eletroacupuntura nos pontos E44, R3 e BP4 resultaria em controle da dor trans e pós-operatória melhor ou igual àquele promovido pela eletroacupuntura nos pontos BP6, E36 e VB34 e pela morfina. Trinta e seis cadelas submetidas à cirurgia eletiva de OSH foram distribuídas em blocos ao acaso em três grupos com 12 animais. Em dois grupos foi realizada eletroacupuntura denso-dispersa, com frequência de 3 e 200Hz, sendo que, no primeiro grupo (GEA), foram estimulados os pontos BP4, E44, R3 e, no segundo grupo (GEB), os pontos BP6, E36, VB34...

Thirty-six dogs undergoing elective ovariohysterectomy surgery were randomly distributed into 3 groups of 12 animals each. In the first group, dense-dispersed electroacupuncture was performed with a frequency of 3-200 Hz in SP4, ST44, KID3 points and 1.5mL of saline was given intramuscularly (GEA group). For the second group, dense-dispersed electroacupuncture was performed with a frequency of 3-200 Hz in SP6, ST36, GB34 points and 1.5mL of saline given intramuscularly (GEB group)...

Successful practice of electroacupuncture analgesia in equine surgery.

Electroacupuncture analgesia was used for surgery in horses and donkeys. A KWD-808 electrical stimulator was used to incrementally induce a dense, dispersed wave output at frequencies from 20 to 55 Hz, which was maintained at a frequency of 55 Hz, and to change the amplitude of the wave to the best grading number for the suggested operation in each animal. Induction of analgesia lasted for 20-30 minutes, and the effect of analgesia was maintained for 20-45 minutes depending on the type of surgery performed. The exhibited clinical signs, physical examination data, and the responses of all animals were used for evaluating the periods of analgesia. Although the majority of the cases (95%) had no response to strong surgical pain, they experienced significant increases in heart rates and respiratory rates during induction. The lack of pain, relaxed surgical procedures, reduced intraoperative bleeding, and improved healing without complications were all definite benefits of using electroacupuncture analgesia in surgery. Thus, this study has provided surgical evidence supporting the effectiveness of electroacupuncture analgesia, as well as confirming its reliability, in the field of equine anesthesia and surgery.

Electroacupuncture ameliorates experimental colitis induced by TNBS through activation of interleukin-10 and inhibition of iNOS in mice

PURPOSE:To study the anti-inflammatory actions of electroacupuncture (EAc) on an experimental colitis model in mice.METHODS:Thirty-eight male Swiss mice, divided in five groups, were subjected to induction of colitis by TNBS in 50% ethanol. Saline (SAL) and ethanol (ETNL) groups served as controls. TNBS+EAc and TNBS+ dexamethasone subgroups were treated with EAc 100Hz and dexamethasone (DEXA) 1 mg/Kg/day, respectively. After three days, a colon segment was obtained for quantification of myeloperoxidase (MPO) activity, immunohistochemistry for iNOS, malondialdehyde (MDA) and cytokines (IL-1β and IL-10).RESULTS:Neutrophilic activity, assayed as MPO activity, was significantly higher in the TNBS colitis group than that in the saline control group. TNBS+EAc group showed suppression of IL-10 in the colon. EAc treatment significantly reduced the concentration of MDA and the expression of iNOS, as compared to the other groups. CONCLUSION: Electroacupuncture 100Hz applied to acupoint ST-36 promotes an anti-inflammatory action on the TNBS-induced colitis, mediated by increase of IL-10 and decrease of iNOS expression.

Eletroacupuntura para tratamento de hipotensão induzida por isofluorano em cavalos / Electroacupuncture treatment for isoflurane induced hypotension in horses

Objetivou-se avaliar a eficiência do tratamento da hipotensão arterial com eletroacupuntura comparativamente à dobutamina em equinos. Foram avaliados seis cavalos adultos, saudáveis, mantidos em anestesia inalatória, com isofluorano, em ventilação mecânica. Após a estabilização da anestesia, foi induzida hipotensão arterial, através do incremento da concentração do isofluorano, iniciando-se um dos tratamentos: DOB: dobutamina (1,5µg kg-1 min-1, infusão contínua intravenosa); EA: estímulo elétrico no acuponto pericárdio 6 (PC6), bilateralmente; SHAM: estímulo elétrico em ponto falso de acupuntura. Foram mensurados: frequência cardíaca (FC), pressão arterial média (PAM), temperatura retal (T), concentração final expirada de isofluorano (ETiso), variáveis hemogasométricas, concentração sérica de aspartato aminotransferase (AST) e creatina fosfoquinase (CK), tempo e qualidade da recuperação pós-anestésica. Houve incremento na PAM de 50%, 36,6% e 7,5% nos tratamentos DOB, EA e SHAM, respectivamente. Não houve diferença entre os grupos nas variáveis hemogasométricas, FC, T, ETiso, CK, AST, tempo e qualidade de recuperação pós-anestésica. Conclui-se que o tratamento com dobutamina foi mais efetivo para o tratamento da hipotensão em cavalos sob anestesia inalatória quando comparado ao estímulo elétrico do acuponto PC6 ou ponto falso de acupuntura...

This study aimed to evaluate the efficacy of electroacupuncture compared to the dobutamine treatment of hypotension in equines. Six adult horses were maintained in isoflurane anesthesia with mechanical ventilation. After anesthesia was established, the isoflurane concentration was raised until hypotension was achieved. After that the animals were treated with a constant rate of 1.5mg kg -1min-1 intravenous dobutamine (DOB), electroacupunture to pericardium 6 (PC-6) acupoint (EA) and false point treatment (SHAM). Heart rate (HH), median arterial blood pressure (MAP), rectal temperature (T), isoflurane end-tidal concentration, arterial blood gases, creatine kinase (CK), aspartate transaminase (AST), recovery time and quality of recovery were investigated. The MAP increased 50%, 36.5% and 7.5%% in DOB, EA and SHAM treatments, respectively. HH, T, arterial blood gases, CK, AST, recovery time and quality of recovery did not differ among treatments. It was concluded that the dobutamine treatment was more effective than EA and SHAM treatments for the reversion of isoflurane induced hypotension in horses...

Effects of maropitant, acepromazine, and electroacupuncture on vomiting associated with administration of morphine in dogs.

OBJECTIVE: To evaluate effects of maropitant, acepromazine, and electroacupuncture on morphine-related signs of nausea and vomiting in dogs and assess sedative effects of the treatments. DESIGN: Randomized controlled clinical trial. ANIMALS: 222 dogs. PROCEDURES: Dogs received 1 of 6 treatments: injection of saline (0.9% NaCl) solution, maropitant citrate, or acepromazine maleate or electroacupuncture treatment at 1 acupoint, 5 acupoints, or a sham acupoint. Morphine was administered after 20 minutes of electroacupuncture treatment or 20 minutes after injectable treatment. Vomiting and retching events and signs of nausea and sedation were recorded. RESULTS: Incidence of vomiting and retching was significantly lower in the maropitant (14/37 [37.8%]) group than in the saline solution (28/37 [75.7%]) and sham-acupoint electroacupuncture (32/37 [86.5%]) groups. The number of vomiting and retching events in the maropitant (21), acepromazine (38), 1-acupoint (35), and 5-acupoint (34) groups was significantly lower than in the saline solution (88) and sham-acupoint electroacupuncture (109) groups. Incidence of signs of nausea was significantly lower in the acepromazine group (3/37 [8.1%]) than in the sham-acupoint group (15/37 [40.5%]). Mean nausea scores for the saline solution, maropitant, and sham-acupoint electroacupuncture groups increased significantly after morphine administration, whereas those for the acepromazine, 1-acupoint electroacupuncture, and 5-acupoint electroacupuncture groups did not. Mean sedation scores after morphine administration were significantly higher in dogs that received acepromazine than in dogs that received saline solution, maropitant, and sham-acupoint electroacupuncture treatment. CONCLUSIONS AND CLINICAL RELEVANCE: Maropitant treatment was associated with a lower incidence of vomiting and retching, compared with control treatments, and acepromazine and electroacupuncture appeared to prevent an increase in severity of nausea following morphine administration in dogs.

Alterações hematológicas em cães (Canis lupus familiaris) após tratamento com eletroacupuntura / Haematological changes in dogs (Canis lupus familiaris) after treatment with electroacupuncture

A acupuntura, é uma terapia que cada vez mais adquire uma credibilidade no mundo ocidental, a sua indicação pode ser para pacientes anêmicos e imunossuprimidos, e outras afecções. O experimento foi realizado com oito cães adultos, sendo 4 fêmeas e 4 machos. O estudo consistiu em análise das concentrações das células vermelhas e brancas avaliado em 4 tratamentos: controle (T0), acupuntura (T1), eletroacupuntura unilateral (T2) e eletroacupuntura bilateral (T3). Os acupontos utilizados foram intestino grosso 4, intestino grosso 11 e estômago 36. Todos os animais passaram por todos os tratamentos com um intervalo de 7 dias para cada tratamento. Os hemogramas séricos foram verificados 20 minutos antes do início do tratamento (M0), logo após o tratamento (M1), e 60 minutos (M2) e 120 minutos (M3) após o tratamento. O resultado da série vermelha não foi significativo, mas notou-se somente uma diminuição significativa da concentração média corpuscular (CHCM) (p<0,05) no tratamento T1 no M1 em comparação aos outros tratamentos; notou-se também uma redução significativa (p<0,05) na concentração plaquetária de T1, T2 e T3 em comparação ao grupo controle. A eletroacupuntura pode levar a uma trombocitopenia, quando estimulado estes pontos, provavelmente por um estímulo parassimpaticomimético.

Acupuncture is an alternative therapy which increasingly acquires credibility in the Western Hemisphere and it is indicated for anemic and immunosuppressed patients, as well as for other diseases. The experiment was performed with 8 adult dogs, 4 females and 4 males. The study consisted to analyze the concentrations of white and red cells evaluated at four treatments: controls (T0), acupuncture (T1), unilateral electroacupuncture (T2), and bilateral electroacupuncture (T3). The acupoints utilized were: 4 large intestine, 11 small intestine and 36 stomachs. All animals experienced all treatments with an interval of 7 days to each treatment. The serum hemograms were verified 20 minutes prior to initiation to treatment (M0), at the end of the treatment (M1), 60 minutes after treatment (M2) and 120 minutes post-treatment (M3). The results revealed that the red series was not significant, but there was only a significant decrease in medium corpuscular concentration (p<0.05) at T1 of M1 as compared to the other treatments; also there was a significant reduction (p<0.05) in the platelet concentration at T1, T2 and T3 as compared to controls. The electro-acupuncture may lead to thrombocytopenia, when stimulating these points, probably by a parasympathetic stimulus.

Electroacupuncture versus morphine for the postoperative control pain in dogs / Eletroacupuntura versus morfina para o controle da dor pós-operatória em cães

PROPOSE: To compare the postoperative analgesic effects of electroacupuncture, morphine or sham acupuncture in dogs undergoing mastectomy. METHODS: Thirty client-owed dogs undergoing to mastectomy were randomly assigned to three groups of 10 animals each and received either morphine (T-M), the electroacupuncture (T-EA) or sham procedure (T-Sham). Pre-anesthetic medication was acepromazine (0.05 mg kg-1, IM). Anesthesia was induced with propofol (4 to 5 mg kg-1, IV) and maintained with isoflurane. Postoperatively pain degree was assessed using a numerical rating scale. Dogs were scored at 1, 3, 6 and 12 hours post-extubation. If the pain score was ≥6, supplemental morphine was administered. Serum cortisol concentration was measured before pre-anesthetic medication, at 45 minutes after the anesthetic induction, and at 1, 3 and 6 hours post-extubation. RESULTS: The pain score did not differ among the treatments, but rescue analgesia was lower in the T-EA group (2 of 10 dogs), when compared with T-Sham (6 of 10 dogs) and T-M (6 of 10 dogs) groups. Serum cortisol concentration did not differ among the treatments. CONCLUSION: Electroacupuncture reduces the postoperative analgesic requirement and promotes satisfactory analgesia in dogs undergoing mastectomy.

OBJETIVO: Comparar o efeito analgésico pós-operatório mediado pela aplicação de morfina, eletroacupuntura ou pontos falsos de acupuntura em cadelas submetidas à mastectomia. MÉTODOS: Trinta cadelas encaminhadas para mastectomia foram aleatoriamente distribuídas em três grupos de dez animais cada, sendo tratadas com morfina (T-M), eletroacupuntura (T-EA) ou pontos falsos de acupuntura (T-sham). A medicação pré-anestésica (MPA) foi realizada com acepromazina (0,05 mg kg-1, IM), seguindo-se a indução e manutenção anestésica com propofol (4 a 5 mg kg-1, IV) e isofluorano, respectivamente. O grau de analgesia foi avaliado 1, 3, 6 e 12 horas após a extubação traqueal, empregandose a escala descritiva numérica. Animais, cujos escores foram ≥6 receberam analgesia de resgate com morfina (0,5 mg kg-1, IM). A concentração sérica de cortisol foi avaliada antes da MPA, aos 45 minutos após a indução anestésica e 1, 3 e 6 horas após a extubação traqueal. RESULTADOS: O escore de dor não variou entre os tratamentos, porém a analgesia resgate foi menos frequente no T-EA (2 de 10 animais), em relação ao T-sham (6 de 10 animais) e ao T-M (6 de 10 animais). CONCLUSÃO: A eletroacupuntura reduz o requerimento analgésico pós-operatório e confere analgesia satisfatória em cadelas submetidas à mastectomia.

PURPOSE: [corrected] To compare the postoperative analgesic effects of electroacupuncture, morphine or sham acupuncture in dogs undergoing mastectomy. METHODS: Thirty client-owed dogs undergoing to mastectomy were randomly assigned to three groups of 10 animals each and received either morphine (T-M), the electroacupuncture (T-EA) or sham procedure (T-Sham). Pre-anesthetic medication was acepromazine (0.05 mg kg(-1), IM). Anesthesia was induced with propofol (4 to 5 mg kg(-1), IV) and maintained with isoflurane. Postoperatively pain degree was assessed using a numerical rating scale. Dogs were scored at 1, 3, 6 and 12 hours post-extubation. If the pain score was ≥6, supplemental morphine was administered. Serum cortisol concentration was measured before pre-anesthetic medication, at 45 minutes after the anesthetic induction, and at 1, 3 and 6 hours post-extubation. RESULTS: The pain score did not differ among the treatments, but rescue analgesia was lower in the T-EA group (2 of 10 dogs), when compared with T-Sham (6 of 10 dogs) and T-M (6 of 10 dogs) groups. Serum cortisol concentration did not differ among the treatments. CONCLUSION: Electroacupuncture reduces the postoperative analgesic requirement and promotes satisfactory analgesia in dogs undergoing mastectomy.

Clinical effect of additional electroacupuncture on thoracolumbar intervertebral disc herniation in 80 paraplegic dogs.

The clinical efficacy of electroacupuncture and acupuncture in combination with medication for the treatment of thoracolumbar intervertebral disc herniation was investigated in paraplegic dogs with intact deep pain perception. To evaluate the additional effect of electroacupuncture, dogs treated with conventional medicines alone were compared to dogs treated with electroacupuncture and acupuncture and conventional medicine. Medical records of 80 dogs were reviewed for this investigation and classified into two groups undergoing different treatment methods: (1) treatment with conventional medicine alone (Group C, n = 37) and (2) treatment with conventional medicine combined with electroacupuncture and acupuncture (Group CE, n = 43). Prednisone was the conventional medicine and electroacupuncture was applied at GV07 and GV02-1 at 0.5-2.5 mV, mixed Hz of 2 and 15 Hz for 25-30 min. Acupuncture was performed locally at urinary bladder meridian points near the lesion, and bilaterally distantly at GB30, GB34, and ST36. Treatment efficacy was evaluated by post-operative neurologic function, ambulation, relapse, complication, and urinary function. Ambulation recovery was more prevalent in Group CE than Group C (p = 0.01) and recovery of ambulation and back pain relief time was shorter in Group CE compared to Group C (p = 0.011 and 0.001, respectively). Relapse rate was significantly lower in Group CE (p = 0.031). The results suggest that a combination of electroacupuncture and acupuncture with conventional medicine is more effective than conventional medicine alone in recovering ambulation, relieving back pain, and decreasing relapse. Electroacupuncture and acupuncture is thus a reasonable option for the treatment of intervertebral disc herniation in paraplegic dogs with intact deep pain perception.

Effects of electroacupuncture at Zusanli and Baihui on brain-derived neurotrophic factor and cyclic AMP response element-binding protein in the hippocampal dentate gyrus.

Previously, we observed that electroacupuncture (EA) at ST36 (Zusanli) and GV20 (Baihui) enhanced cell proliferation and neuroblast differentiation in the rat dentate gyrus. In this study, we investigated the possible mechanisms of EA in this effect. For this, we applied EA at ST36 and GV20 of Wistar rats (13-week-old) once a day for 3 weeks. Application of EA at these acupoints significantly increased the number of phosphorylated cyclic AMP response element-binding protein (pCREB)-immunoreactive cells in the dentate gyrus. In addition, EA significantly increased the levels of brain-derived neurotrophic factor (BDNF) and pCREB protein in the dentate gyrus. The administration of K252a, an inhibitor of BDNF receptor, significantly reduced cell proliferation in the subgranular zone of dentate gyrus. These results suggest that EA significantly increased neuroblast plasticity via pCREB and BDNF activation in the dentate gyrus.

Comparison of decompressive surgery, electroacupuncture, and decompressive surgery followed by electroacupuncture for the treatment of dogs with intervertebral disk disease with long-standing severe neurologic deficits.

OBJECTIVE: To compare the effects of decompressive surgery (DSX), electroacupuncture (EAP), and DSX followed by EAP (DSX + EAP) for the treatment of thoracolumbar intervertebral disk disease (IVDD) in dogs with severe neurologic deficits of > 48 hours' duration. DESIGN: Retrospective case series and prospective clinical trial. ANIMALS: 40 dogs between 3 and 6 years old and weighing between 10 and 20 kg (22 and 44 lb) with long-standing (> 48 hours) clinical signs of severe neurologic disease attributable to thoracolumbar IVDD. PROCEDURES: Thoracolumbar medullar injury was classified on the basis of neurologic signs by use of a scale ranging from 1 (least severe) to 5 (most severe). The DSX dogs (n = 10) were retrospectively selected from those that underwent DSX for the treatment of thoracolumbar IVDD. In addition, 19 dogs received EAP alone and 11 dogs underwent DSX followed by EAP (DSX + EAP). Outcome was considered a clinical success when a dog initially classified as grade 4 or 5 was classified as grade 1 or 2 within 6 months after the end of treatment. RESULTS: The proportion of dogs with clinical success was significantly higher for dogs that underwent EAP (15/19) than for dogs that underwent DSX (4/10); the proportion of dogs with clinical success for dogs that underwent DSX + EAP was intermediate (8/11). CONCLUSIONS AND CLINICAL RELEVANCE: EAP was more effective than DSX for recovery of ambulation and improvement in neurologic deficits in dogs with long-standing severe deficits attributable to thoracolumbar IVDD.
