There is a variety of therapeutic modality for herniated nucleus pulposus. Recently the low level laser has come into use for treatment for it. We treated two patients suffered from herniated nucleus pulposus of the central type of $L_{3,4}$ level, with He-Ne, $CO_2$ and Ga Al As laser simultaneously daily under hospitalization. In order to determine the efficacy of treatment, we used the "visual analogue scale" and its improvement rate. The results were as follows; Case I complained of gait disturbance, and hypoesthesia on the lateral side of the left lower leg, as and as low back pain. At the 15th day after treatment, VAS improvement rate was 40%, and the gait disturbance and hypoesthesia were markedly improved. 35th days after tratement, VAS improvement rate was 80%. Case II complained only of low back pain. At the 15th day after treatment, the VAS improvement rate was 68%, and at 20 days after treatment it was 84%. We sugsest that, using the low level laser for treatment of herniated nucleus pulposus increased the cartilage entrophism, and inhibitory effects of the inflammatory materials such as acid glycosaminoglycan by its anti-inflammatory and analgesic effects.

The purpose of this study was to determine the effects of laser Irradiation on Human plasma $\beta-endorphin$ levels, by treating with low level helium-neon (He-Ne) and Infrared(lR) laser. The Laser was fixed frequency of 2400Hz by continuous scanning and irradiating time was 8 minutes each point. Blood samples were taken at before, after, after 15min's treatment and Plasma $\beta-endorphin$ was measured by radioimmunoassay. The samples for this study were 6 normal subjects(3male, 3female). The data were analyzed by paired t-test, one-way ANOVA and simple regression. The results of this study were as follows : 1. The human plasma $\beta-endorphin$ levels were noted as significant increase in after-treatment $(22.84{\pm}10.63pg/ml)$ as compared with before-treatment $(16.96{\pm}9.23pg/ml)$ and significant increase in after 15min's $(27.27{\pm}8.81pg/ml)$ as compared with after-treatment (p<0.05). 2. There were no significant changes in plasma g-endorphin levels between male and female. 3. The human plasma $\beta-endorphin$ levels were high associated in between session reliability (p<0.05).

In this module, RED Light Emitting Diode was employed to replace for Low level He-Ne laser for medical applications Each experiment was performed to irradiation group and non-irradiation group for both Dog bone marrow and Rat tissue cells. MTT assay method was chosen to verify the cell increase of two groups and the effect of irradiation on cell proliferation was examined by measuring 590nm transmittance of ELISA reader. As a result, the cell increase of 37% on Dog bone marrow, 23% on Rat tissue cells was verified m irradiation group as compared to non-irradiation group. The fact that specific wavelength irradiation has an effect on cell vitality and proliferation is known through this study.

대상포진후 신경통의 치료를 위하여 사용하였던 스테로이드로 인한 고혈당증을 동반한 환자를 치료한 결과를 다음과 같이 요약한다. 첫째, 통증치료실에서 흔히 쓰이는 약물 중에는 고혈당증을 유발하는 것이 많으므로 처치전에 고혈당이 영향을 주는 다른 질환의 유무를 확인하도록 한다. 둘째, 스테로이드 사용으로 인하여 발생되는 일시적인 고혈당중의 경우에는 스테로이드 사용 중단으로 회복이 가능하나 잠재되어 있던 당뇨병의 발현시는 지속적인 당뇨병의 치료를 필요로 한다. 셋째, low level laser therapy는 혈당치에 영향을 미치지 않는 통증치료법으로 유용하게 사용될 수 있다.

Objective: We have studied the effects of acupuncture and low level He-Ne laser therapy(LLLT) at $SI_3$, $BL_{40}$ on the tibial, sural nerve injury due to sports-damage or traffic accident and L5 spinal nerve ligature model like general herniation of nucleus pulposus(HNP) in a rat of neuopathic pain. Methods: A model of neuropathic pain was made by injuring tibial nerve and sural nerve while common peroneal nerve was maintained. Also, it was made by isolating left 5th lumbar spinal nerve. Three weeks after the neuropathic surgery, acupuncture and LLLT was injected at $SI_3$,$BL_{40}$ one time a day for one week. LLLT was divided three groups, that is LLLT-1(5mW), LLLT-2(10mW) and LLLT-3(30mW). After that, we examined the withdrawal response of neuropathic rats' legs by Von frey filament and acetone stimulation. And also we examined c-Fos, Nocieptin and KOR-3 in the midbrain central gray of neuropathic rats. Results: As we have observed the effect of mechanical allodynia, LLLT-3 group were diminished on 4 day, 5 day, 6 day and 7 day in the resection model compared with control model, LLLT-1 group were diminished on 5 day, LLLT-2 group were diminished on 3 day and 6 day, LLLT-3 group were diminished on 3 day, 4 day, 5 day, 6 day and 7 day in connected model compared with control group. As we have observed the effect of cold allodynia, LLLT-3 group were diminished on 7 day in the resection model compared with control model, LLLT-1 group were diminished on 6 day, 7 day, LLLT-3 group were diminished on 7 day in connected model compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, LLLT-3 were diminished in resection model compared with control group, LLLT-1 group were diminished in connected model compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, resection model were not increased compared with control group, LLLT-1 group and LLLT-3 group were increased in connected model compared with control model. As we have observed the effect of activity of KOR-3 in the central gray part, resection model were not increased compared with control group, LLLT-3 group were increased in connected model compared with control model. Conclusions: We have noticed that LLLT-1 and LLLT-3 group have more controllable effect than acupuncture group. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin and KOR-3 have effectively to control pain. Therefore We have to follow up about that.

Objectives : This research was performed to investigate the effect of invasive low level laser acupuncture therapy(LLLAT) at Yolgyol+yogu(LU7+LR5) on weight gain, food intake, food efficiency, lipid metabolism and liver function in hyperlipemia rats. Methods : Experimental groups were divided into high fat diet cup(Control group), high fat diet and 15 mW/5 min LLLAT at LU7+LR5(15 mW/5 min group), 15 mW/10 min LLLAT at LU7+LR5(15 mW/10 min group), 30 mW/5 min LLLAT at LU7+LRS(30 mW/5 min group), 30 mW/10 min LLLAT at LU7+LR5(30 mW/10 min group). LLLAT was treated at the 15,30mW-5,10min once a 2day during 5 weeks. Results : Body weight was decreased significantly in 30 mW/s min group and 30 mW/10 min group compared with control group. Food intake was decreased significantly in 15 mW/5 min group and 15 mW/10 min group compared with control group. Food efficiency was decreased significantly in 30 mW/10 min group compared with control group. In the lipid metabolism, total cholesterol, HDL-cholesterol and free fatty acid were increased significantly in 15 mW/5 min group and 30 mW/10 min group compared with control group. LDL-cholesterol was increased in 30 mW/10 min group and phospholipids was decreased significantly in all experimental group compared with control group. triglyceride was not showed significant result in all experimental group. In the liver function, AST was not showed significant result in all experimental group, ALT and ALP were increased significantly in 30 mW/10 min group, ALP was decreased in 30 mW/5 min group compared with control group. Conclusions : LLLAT at LU7 and LR5 can manage hyperlipemia by controlling body weight, food intake, food efficiency ratio and lipid metabolism.
