Objectives : The purpose of this study is to review laser acupuncture studies to find possibility for applying high intensity laser to acupuncture and moxibustion treatment. Methods : Searching papers was performed using search engines of five electronic databases, including Pubmed, Thomson ISI, EMBASE, Sciencedirect, and EBSCO, from inception to May 2011 without language limitation. Inclusion criteria were clinical studies with human, randomized controlled trials (RCTs), case-control studies, and case reports. Selecting papers was performed with titles and abstracts in first step, scrutinize full text in second step, and then the extrated data was analyzed by two authors independently. The methodological quality for RCTs was evaluated using Jadad's scale. Results : Total 8 papers, (3 RCTs, 5 controlld studies, and 1 case reports), were finally selected. The study dealt with surgical laser, argon and $CO_2$ laser was one for each, with GaAs laser was two, and with new semiconductor laser, GaN, were four. The output range was from 110 mW to 15 W. The study diseases were alcohol addiction, knee osteoarthritis, bronchopneumonia and asthma for children, and circulation. All studies reported positive effect. The methodological quality in all RCTs was low because of below 3 points and all studies had few subject numbers. Conclusions : We suggest that high intensity laser can be applied to acupuncture and moxibustion. Further rigorous and well-designed study will be needed for various disease. The oriental medical society needs to take active measures to study and clinical application of acupuncture and moxibustion treatment with high intensity laser.

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.

Objectives : The aim of the study is to investigate the effects of low level laser treatment (LLLT) on the gait behavior in the rat model of arthritis. Methods : Knee arthritis was induced by the injection of $125{\mu}l$ of Complete Freund's Adjuvant(CFA) into the right hind knee joint cavity. Arthritic rats were divided 3 groups; arthritis group was used for control(CON), 10 min of laser treated group(LSR10), and 30 min of laser treated group(LSR30). LLLT was applied to KI 1 for 11 times under gaseous anesthesia. We performed several analyses under catwalk test including stand and swing time, duty cycle of paw steps, intensity and print area of steps, and stride length. Results : Stand and duty cycle of paw steps were increased significantly at 12 days after arthritis induction in LSR30 group. Swing time was decreased significantly at 12 days after arthritis induction in LSR10 group. In the analysis of intensity, print area and stride length, however, results did not show statistical significance during the time point of experiments. Conclusions : The data suggest that LLLT on the rat model of CFA induced arthritis showed beneficial effects by increase of stand time and duty cycle of paw steps and decrease of swing time. Therefore, LLLT could be useful option to improve gait discomfort in arthritis patients.
