Objectives: This study was performed to investigate the effects of acupuncture therapy(AT, AT-9), electro-acupuncture therapy(EAT) and low level laser acupuncture therapy(LAT) at LRJ on the focal ischemia-induced by intraluminal filament insertion in rats. Methods : In the present syudy, the focal ischemia was induced by Intraluminal filament insertion into left middle cerebral artery. The subjects were divided into five groups after focal brain ischemia. (n=15, in each group) : Control with no treatment, AT with acupuncture at $LR_3$, AT-9 with acupuncture at $LR_3$ and rotating 9 times in a clockwise direction, EAT with electro-acupuncture at $LR_3$ and LAT with invasive laser acupuncture at $LR_3$. Anti-apoptotic and neuroprotective effects of acupuncture were observed by mGluR5 mRNA, Bax mRNA, Bcl-2 mRNA, Cytochrome C protein, Cresyl violet-stain and Choline acetyltransferase (ChAT)-stain in the hippocampus. Results: 1. In LAT, mGluR5, Cresyl violet-stain and ChAT-stain were increased. 2. In LAT, Cytochrome C protein was decreased. 3. In AT-9, Bax, Cytochrome C protein and the Bax/Bcl-2 ratio were decreased. 4. In AT-9, Bcl-2, Cresyl violet-stain and ChAT-stain were increased. 5. In EAT, Bcl-2 and Cresyl violet-stain were increased. Conclusions: These results suggests that LAT and AT-9 show anti-apoptotic and neuro-protective effects and that LAT and AT-9 may be useful for managing stroke by focal brain ischemia.

Acupuncture therapy has been proved to be effective for diverse diseases, symptoms, and conditions in numerous clinical trials. The growing popularity of acupuncture therapy has triggered the development of modern acupuncture-like stimulation devices (ASDs), which are equivalent or superior to manual acupuncture with respect to safety, decreased risk of infection, and facilitation of clinical trials. Here, we aim to summarize the research on modern ASDs, with a focus on featured devices undergoing active research and their effectiveness and target symptoms, along with annual publication rates. We searched the popular electronic databases Medline, PubMed, the Cochrane Library, and Web of Science, and analyzed English-language studies on humans. Thereby, a total of 728 studies were identified, of which 195 studies met our inclusion criteria. Electrical stimulators were found to be the earliest and most widely studied devices (133 articles), followed by laser (44 articles), magnetic (16 articles), and ultrasound (2 articles) stimulators. A total of 114 studies used randomized controlled trials, and 109 studies reported therapeutic benefits. The majority of the studies (32%) focused on analgesia and pain-relief effects, followed by effects on brain activity (16%). All types of the reviewed ASDs were associated with increasing annual publication trends; specifically, the annual growth in publications regarding noninvasive stimulation methods was more rapid than that regarding invasive methods. Based on this observation, we anticipate that the noninvasive or minimally invasive ASDs will become more popular in acupuncture therapy.

Objectives : The purpose of this study was to assess the ability of Extravascular Laser System on pain treatment. Methods : On this study, we carried out with the 9 cases of children who visited in the Department of Pediatrics, OO University Oriental Hospital as pain. 9 children suffering from pain were treated with Extravascular Laser System, and two of these were treated with combined acupuncture. In order to determine the degree of pain relief, a visual analogue scale was used. Results : Extravascular Laser System for pain resulted in a significant decline in the visual analogue scale. For Extravascular Laser System combined with acupuncture, VAS score has fallen by 30% each time compared to 17.5% of Extravascular Laser System only. In 2 cases of chronic pain, VAS score decreased to 0. In 7 cases of acute pain, All of 7 children improved 50% on VAS score, On average VAS score have seen 79.2% reduction. The average treatment times of chronic pain were 5 times, while that of acute pain were 4.1 times. Conclusions : We report the good result of the efficacy of extravascular laser system on children's pain. but, this study's cases were small in number. so more study is need.

The purpose of this study were to 1) determine the analgesic effect of 632.8 nm of helium-neon (He-Ne) laser stimulation on acupuncture point in rat and 2) determine the reversal of analgesic effect by naloxone injection. Eighteen Sprague-Dawley rats were devided into three groups : control (n=6) : laser (n=6), laser stimulation at $3.58\;J/cm^2$ ; and naloxone (n=6), 1 mg/kg of naloxone chloride inject into peritoneum before laser stimulation at $3.63J/cm^2$. Tail-flick latency were measured pretreat and posttreat with hot plate $(55^{\circ}C)$. Data were analyzed using one-way ANOVA and paired t-teat for tail-flick latency. No significant change was noted in the tail-flick latency in either control or naloxone groups. But significant increased in tail-flick latency in taller group. The results suggest that He-Ne laser induced analgesic effect, and endogenous opioids may be involved in He-Ne laser induced analgesia.

Objectives : To find effects of acupuncture, electro-acupuncture, low level He-Ne laser therapy(LLLT) at $TE_5$, $GB_{41}$ in the neuropathic pain. We made experiment on rats ligated L5 spinal nerve like general herniation of nucleus pulposus(HNP). Methods : A model of neuropathic pain was made by isolating Left 5th lumbar spinal nerve of rats. Three days after the neuropathic surgery, acupuncture and LLLT, electro-acupuncture was injected at $TE_5$, $GB_{41}$ one time a day for a week. Each group was divided two. one is opposite side performed the surgery which is right, another is left side performed the surgery. After that, the author examined the withdrawal response of neuropathic rats' legs by van Frey filament and acetone stimulation. And also the author examined c-Fos, Nociceptin and KOR-3 in the midbrain central gray of neuropathic rats. Results : As we have observed the effect of mechanical allodynia, LT-R group were diminished on 6th day compared with control group, EA-L group, EA-R group and LT-L group were diminished on 7th day compared with control group. As we have observed the effect of cold allodynia, EA-R group were diminished on 6th day, 7th day compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, EA-R group and LT-R group were diminished compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, EA-R group were a little increased compared with control group but it is not reliability. As we have observed the effect of activity of KOR-3 in the central gray part, EA-R group were significantly increased compared with control group. Conclusions : We have noticed that effect of acupuncture at opposite side of sickness and powerful stimulation could be more effective, because of EA-R group have more controllable effect all test we have done on the other hand EA-L group have only effect on mechanical allodynia. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin have effectively to control pain. Therefore We have to follow up about that.

Background: Myofascial pain dysfunction syndrome (MPDS) is the most common type of temporomandibular disorder. This study compared the efficacies of low-level diode laser therapy (LLLT) and laser acupuncture therapy (LAT) in the treatment of MPDS. Methods: This double-blind randomized controlled clinical trial included 24 patients with MPDS who were randomly divided into two equally sized groups. Patients in the LLLT group received 12 sessions of low-level diode laser irradiation applied to the trigger points of the masticatory muscles during 1 month. The same protocol was also used in the LAT group according to the specific trigger points. We measured pain intensity and maximum mouth opening in both groups at baseline, during treatment, and 2 months after treatment completion. Results: The pain intensities decreased from 6.58±1.31 to 0.33±0.65 and from 7.08 ± 1.37 to 0 in the LLLT and LAT groups, respectively. The maximum mouth openings increased from 32.25 ± 8.78 mm to 42.58 ± 4.75 mm and from 33 ± 6.57 mm to 45.67 ± 3.86 mm in the LLLT and LAT groups, respectively. Pain intensity (P = 0.839) and level of maximum mouth opening (P = 0.790) did not differ significantly between the groups. Conclusion: Our results showed similar efficacy between LLLT and LAT in the treatment of MPDS signs and symptoms.

목적 : 태충($LR_3$)에 자침을 하는 것이 쥐의 유방 조직에 미치는 혈역학적 변화를 측정하기 위하여 diffuse optical imaging 기법을 사용하였다. 방법 : 실험에 사용한 쥐는 자침을 하지 않은 대조군 7마리, 태충에 자침을 한 실험군 8마리로 총 2개의 군으로 나누었다. 몸무게 170g 정도의 건강한 암컷 쥐는 100% 산소와 1.5% isoflurane을 혼합한 것을 이용하여 마취시켰다. 자침은 양 발등의 첫째와 둘째 중족골 사이의 지점인 태충($LR_3$)에 20분간 시행하였다. Beckman Laser Institute and Medical Clinic에서 개발된 modulated imaging system을 이용하여 자침하기 전과 자침하고 있는 동안에 산화혈색소(OHb), 탈산소혈색소(RHb), 총 혈색소(THb)와 조직 산소 포화도($StO_2$)의 영상을 얻었다. 결과 : 실험 결과 태충($LR_3$)에 자침을 한 실험군에서는 대조군에 비하여 유의성이 있는 OHb THb의 감소와 유의성이 없는 RHb의 증가가 나타났다. 결론 : Diffuse optical imaging 기법으로 자침 중에 조직 산소공급과 혈류량의 변화를 확인할 수 있었고, 이는 비침습적으로 자침의 효과를 측정하는 데 활용할 수 있다고 생각한다. 또한 자침으로 인한 유방조직의 혈역학적 조절은 암 검진뿐만 아니라 암 치료에도 다른 치료와 병행하여 활용할 수 있으리라 생각한다.
