  • Objectives : The aim of this study is to evaluate the analgesic effect of electroacupuncture on Jogsamni (ST36) in the collagen-induced arthritis rats and investigate the role played by opioid receptor subtypes $({\mu},\;{\delta},\;{\kappa})$ in the antinociceptive effect of electroacupuncture (EA) In the thermal hyper algesia test. Methods : Immunization of male Sprague-Dawley rats with bovine type H collagen emulsified in incomplete Freund's adjuvant, followed by booster injection 2 weeks later induced collagen-induced arthritis (CIA). The thermal hyperalgesia was evaluated weekly with tail flick latency (TFL). In the fourth week after first immunization, EA stimulation (2 Hz, 0.07 mA, 0.3 ms) was delivered into Jogsamni (5736) for 20 minutes. Analgesic effect was evaluated by using the tail flick latency (TFL) after intraperitoneal injection of normal saline, naloxone, naltrindole and nor-binaltorphimine respectively to CIA rats. Results : The results were as follows; 1. The TFL were gradually decreased in CIA as time elapsed after e immunization of arthrogenic collagen and the maximum value was reached between the third to fifth week. 2. EA stimulation on 5736 inhibited chronic inflammatory pain induced by CIA. 3. The analgesic effect of EA was inhibited by pretreatment of ${\mu}-receptor$ antagonist (naloxone),${\delta}-receptor$ antagonist (naltrindole) and ${\kappa}-receptor$ antagonist (nor-binaltorphimine) respectively. Conclusion : Electroacupuncture has an analgesic effect on the CIA rat and has an antinociception mediated by 8, 5, H receptors.

  • Objectives : to evaluate the analgesic effect of bee venom acupuncture on Choksamni (ST36) in the collagen-induced arthritis rats and investigate the role played by serotonergic receptor subtypes (5-HT1a, 5-HT2a) in the antinociceptive effect of bee venom acupuncture in a thermal hyperalgesia test Methods : Experiments were performed on 5 week-aged 60 male Sprague-Dawley rats according to National Institute of Health guidelines and the ethical guidelines of the International Association for the Study of Pain (IASP). Arthritis was induced with arthrogenic collagen emulsion (Bovine type II collagen ${\mu}g$ with incomplete Freund's adjuvant $100\;{\mu}g$). The onset of arthritis was considered to be present when erythema and swelling were detected in at least one joint. The thermal hyperalgesia was evaluated weekly with tail flick test in the rats of severity grade 3 without any injury at tail and foot (including inflammation, ulceration, snap). In the fourth week after first immunization, the analgesic effect of bee venom acupuncture (Choksamni, ST36) was measured with consecutive tail flick latency after intraperitoneal injection of spiroxatrine (1mg/kg) and spiperone (1mg/kg). Results : Chronic inflammatory pain was induced as time elapsed after the immunization of arthrogenic collagen and the maximum value was reached from third to fifth week. Chronic inflammatory pain induced by CIA was inhibited by bee venom acupuncture on the left ST36. The analgesic effect of bee venom acupuncture was inhibited by intraperitoneal injection of 5-HT1a antagonist spiroxatrine and 5-HT2a antagonist spiperone. Conclusions : Therefore, a conclusion. that the analgesic effect of bee venom acupuncture in the chronic inflammatory pain is partially mediated by 5-HT1a and 5-HT2a receptors can be made.

  • In order to obtain a good result in Arthroscopic ACL Reconstruction by immediate postoperative physical therapy, sufficient analgesia was needed. This study analyzes the analgesic effect of the intra-articular injection with ketorolac, Morphine together with bupivacaine in 80 male patients who had Arthroscopic ACL Reconstruction. On completion of the surgery under spinal anesthesia, the knee was injected with 30ml of 0.25% bupivacaine. Each of the study group received ketorolac and/or morphine, either through parenteral or intra-articular. Total amount of the drug used by Patient Controlled Analgesia(PCA) and Visual Analgesia Scale(VAS) for pain were measured and analyzed. The group which received intra-articular ketorolac or Morphine had a better analgesic effect than other group which received none. The group which received both did not do better in analgesic effect. Intra-articular infusion with either ketorolac or Morphine improved postoperative analgesia in Arthroscopic ACL Reconstruction surgery. However, combined injection did not offer more advantage.

  • Objectives : In this study, we investigated the effect and pathway of contralateral heterotropic electroacupuncture (EA) on pain induced by fonualin in rats. Methods : Acu-points in the right forepaws, HT 7 and PC 7 were stimulated with 3~4mA, 2ms, and 10Hz after 5% formalin (50ul) s.c. injection to the left hind paw. In addition, it was investigated whether the dorsolateral funiculus (DLF), known to be related the descending inhibition, mediates analgesic effects of the contralateral heterotropic EA or whether administration of naltrexone, an opioid antagonist, blocks the effect of EA. Results : The results showed that contralateral heterotropic electroacupuncture (EA) inhibited late phase (63.311.7%) of pain induced by fonualin in the behavioral test, but sham-EA had little effect on pain behavior (85.616.8%) and no analgesic effects after transection of the dorsolateral funiculus (95.718.7%). The pretreatment of naltrexone (10mg/kg, i.p.) could not inhibit the analgesic effects of EA on formalin-induced pain behavior (70.713.1%). Also,EA suppressed formalin injection induced expression of cFos like protein (cFL) in the dorsal homo but not sham-EA. Suppressed expressions of cFL in the spinal cord were eliminated after transection of the ipsilateral dorsolateral funiculus at T10-11 leve1s. However, pretreatment of naltrexone could not prevent the suppressive expressions of cFL at the spinal cord. Conclusions : These results suggest that the analgesic effect of contralateral heterotropic electroacupuncture may be modulated through the dorsolateral funiculus constituting the descending inhibition.

  • It has been known that Gentianae macrophyllae Radix is reputed to be effective in removal of 'Pungseub' and 'Heoyeol', and to be analgesic. Since ancient times, however, there have been many examples of substituting Lycoctoni Radix for Gentianae macrophyllae Radix. For that reason, this experiment was conducted to compare the diuretic, analgesic, anti-inflammatory, anti-pyretic, anti-bacterial effect, and toxicity of Lycoctoni Radix with those of Gentianae macrophyllae Radix. The results obtained in this work were summarized as follows; In the test of acute toxicity, Lycoctoni Radix was found to be toxic in comparison to Gentianae macrophyllae Radix which was found to be non-toxic. Both herbs were found to be diuretic and Gentianae macrophyllae Radix was more effective than the other and to be ineffective for the blood pressure and respiration. Lycoctoni Radix was found to be more analgesic than the other. Gentianae macrophyllae Radix was found to be more anti-inflammatory of the two and both demonstrated anti-pyretic effect. Anti-bacterial effect was detected only in Lycoctoni Radix. It is concluded that Gentianae macrophyllae Radix has mild diuretic, analgesic, anti-inflammatory and anti-pyretic effect, but Lycoctoni Radix, due to its toxicity, can not be substituted for Gentianae macrophyllae Radix.

  • This experiment was designed to investigate the analgesic effect of non-invasive electroacupuncture treatment on femoral head osteotomy in dogs. Twelve dogs were divided into 3 groups in this experiment. Electroacupuncture group was non-invasively electrostimulated in Huan Tiao (GB-30) acupoint for 10 minutes by 4.5V, 5Hz for 10 days. Medication group was treated with carprofen (4mg/kg, P.O.) for 10 days. Control group was not treated. Each group was pre-operatively and post-operatively scored by using VAS (Visual Analogue Scale), SDS (Simple Descriptive Scale), NRS (Numerical Rating Scale), and measured serum cortisol levels. The results of VAS, SDS and NRS in electroacupuncture and medication groups were better than those of control group. And, the results of electroacupuncture group were better than those of medication group since 6th day after osteotomy in pain management(p<0.05). But, there were no significances in serum cortisol level among 3 groups. In conclusion, non-invasive electroacupuncture treatment showed sufficient analgesic effect on postoperative pain management after femoral head osteotomy, and VAS, SDS, and NRS scoring system would be adapted in evaluation of pain management.
