Obiecnves : The purpose of this study was to examine the analgesic effect of moxi-tar on a rat model of carrageenan-induced arthritis and the relations between moxi-tar-induced analgesia and endogenous NO and iNOS, cyclooxygenase-2 (COX-2), and c-Fos protein expression in the spinal cord. Methods : Carrageenan-induced arthritis rat model was used to test the effect of moxi-tar as a chronic pain model. After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 4 days. The reduced stepping force of the limb was presumably due to a painful knee, since oral injection of indomethacin produced temporary improvement of weight bearing. Moxi-tar dissolved in ethyl alcohol was injected several acupoints. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 12 hours. Results : Moxi-tar produced significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 9 hours. The magnitude of this improvement was equivalent to that obtained after an oral injection of 3 mg/kg of indomethacin and this improvement of stepping force was interpreted as an analgesic effect. Moxi-tar produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner. Both NO production and iNOS, COX-2 protein expression increased by arthritis were suppressed by moxi-tar. moxi-tar on combination with electroacupuncture (EA) produced more powerful and longer lasting improvement of stepping force of the hindlimb affected by the arthritis than either moxi-tar or EA did. Conclusion : The present study suggest that moxi-tar produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and that moxi-tar-induced analgesia modulate endogenous NO through the suppression of iNOS/COX-2 protein expression.

Objectives: This study was produced to examine the effects of moxibustion that had been played important role to traditional oriental medical treatment on disease. Recently, it was reported that moxi-tar which is generated in the process of moxibustion as burning combustibles decreased nitric oxide(NO) and inducible NO synthase (iNOS) generation in cellular experiments. Methods: Carrageenan-induced arthritis rat model was used to test the effect of moxi-tar as a chronic pain model. Diluted moxi-tar was single injected in several acupoints or combined with electroacupuncture (l ms, 2 Hz, and 2 mA) into contralateral ST36 acupoint for 30 min to assess the synergic effects. After the treatment, behavioral tests measuring stepping force were periodically conducted during the next 12 hours. Endogenous NO and iNOS, cyclooxygenase-2 (COX-2), and c-Fos protein expression in the spinal cord were examined on a rat model of carrageenan-induced arthritis. Results : After the induction of arthritis, rats subsequently showed a reduced stepping force of the affected limb for at least the next 4 days. The reduced stepping force of the limb was presumably due to a painful knee, since oral injection of indomethacin produced temporary improvement of weight bearing. Maxi-tar produced significant improvement of stepping force of the hindlimb affected by the arthritis lasting at least 9 hours. The magnitude of this improvement was equivalent to that obtained after an oral injection of 3 mg/kg of indomethacin and this improvement of stepping force was interpreted as an analgesic effect. Maxi-tar produced the improvement of stepping force of the affected hindlimb in a dose-dependent manner. Both NO production and iNOS, COX-2 protein expression increased by arthritis were suppressed by maxi-tar. Moxi-tar on combination with electroacupuncture (EA) produced more powerful and longer lasting improvement of stepping force of the hindlimb affected by the arthritis than either moxi-tar or EA did. Conclusion : The present study suggest that maxi-tar produces a potent analgesic effect on the chronic knee arthritis pain model in the rat and that moxi-tar-induced analgesia modulate endogenous NO through the suppression of iNOS/COX-2 protein expression.

Purpose: The aim of this study was to report the improvement of Guillain-Barre syndrome after long-term combination treatment with Korean medicine. Methods: A patient was diagnosed with Guillain-Barre syndrome and treated with herbal medicine, acupuncture, pharmacopuncture, moxibustion, and exercise, including quadruped walking after three hospital admissions. To evaluate muscle strength and weakness, we measured manual muscle function, gait pattern, and the speed of quadruped walking. Results: The patient's muscle weakness in the extremities and gait stance were improved. The speed of quadruped walking was increased. Conclusion: We consider that combined treatment with Korean medicine might be effective for the muscle weakness of Guillain-Barre syndrome with a poor prognostic factor. To verify the effectiveness of this treatment, further research is needed.

In this research, in order to improve the heat retention of greenhouse, comparative analysis of the heat flux of the marketed multi-later insulating curtain was carried out. Experiments is conducted by fabricating a test apparatus for investigating the heat flux characteristics. The multi-later insulating curtain used for the experiment was compared using the P, N, S, U and T company, which are commercially available, and the heat flux due to temperature difference between the experimental apparatus and the outside was compared and analyzed. When the internal temperature of the experimental result is the maximum temperature $60^{\circ}C$, the heat flux of multi-later insulating curtain is T Co.($73.1W/m^2$) > S Co.($119.5W/m^2$) > U Co.($155W/m^2$) > N Co.($163.1W/m^2$) > P Co.($177.7W/m^2$). The heat flux means the quantity of heat passing through the unit time per unit area, and the higher the numerical value, the higher the quantity of heat passing through the multi-layer insulating curtain. This can be determined that high heat fluxes produce low heat resistance. Further, it has been found that the weight of the insulating curtain is largely unrelated to the heat insulating property, and the heat insulating curtain having a thickness containing a high internal air layer is excellent in the heat insulating property. In the future when manufacturing a heat insulating curtain, It is judged that it is desirable to manufacture a combination of heat insulating materials that contain a high internal air layer content and that can maintain the air layer even for long-term use while minimizing the volume.

Multiple system atrophy is a neurodegenerative disease that causes diverse bodily dysfunctions (cerebellar, pyramidal, automatic, and urological, in any combination), as well as Parkinsonism. Patients with multiple system atrophy commonly display antecollis, a condition where the patient's head tilts forward more than 45 degrees. Despite its common occurrence in these patients, no current standardized therapies are effective for treating antecollis. In this study, Korean medicinal treatments, including Chuna manual therapy, pharmaco-acupuncture, bee venom acupuncture, acupuncture, herbal medicine, and moxibustion therapy, were administered to the patient over a 27-day period. After the treatment, assessments of the head position on the EPIS-PD scale (Part I) and at a standing position from the side (Part II) both revealed improvements. As the head flexion angle decreased, the patient's head posture improved, as determined by a decrease in angle from 80 degrees to 30 degrees in the upright, standing position. As a result, patients who previously were unable to walk without the support of walking frames could now roam freely and independently, with significant increases in both walking speed and distance. In essence, this study suggests that Korean medicine is an effective treatment for patients with multiple system atrophy who suffer from antecollis and gait disorders.

Objectives : To observe the effect of 4 kinds of Korean medicine and complex extracts on the anti-stress of chronic mild stress Rat model, so as to find out the machanism of its pharmacological effects. Methods : 64 healthy SD Rats were randomly divided into 8 groups. Model Design by chronic stress(CSM), and carried out the forced swimming test. We investigated the body weight, feed and water intake, feed conversion ratio and measured parameters to changes in swimming time, immobility time, 2 and 24 hours of feces, corticosterone hormone and blood glucose level. Results : In this experiments, body weight gain and feed intake were higher in all korean medicinal herb group. Swimming time were increased by Zizyphus jujuba and Gagamsanzointang(SZT) groups and immobility time was significantly lower by Zizyphus jujuba and Fluoxetine(FLX) groups. The result of corticosterone hormone level were significantly lower in Fluoxetine(FLX) and Gagamsanzointang(SZT) but blood glucose was not significantly difference. In 2 hours after fecal frequency result were significantly lower in Zizyphus jujuba group. but SZT group were increased. This result caused by acute stress but 24 hours of feces were restored to normal. Conclusions : 5 kind of Korean Medicinal Herbs extracts has good anti-stress effects, and also to clear the circulatory system and regulate blood glucose and improve bowel function. We suggest that use a single Korean medicine rather than the combination to relieve stress.

브라시노스테로이드는 식물의 생장과 발육 과정에 있어서 중요한 역할을 담당 할 뿐 아니라 생물학적/ 비 생물학적 스트레스에 대한 복합 저항성을 보인다고 알려져 있다. 따라서 본 연구에서는 브라시노스테로이드와 광범위스트레스 내성을 연결하는 중요한 생물학적 네트워크를 이해하기 위해, Agilent Arabidopsis $4{\times}44K$ oligo chip을 이용하여 브라시노스테로이드 신호가 강화된 bes1-D 계통의 전 전사체 비교분석을 수행하였다. 그 결과 bes1-D 계통에서 DEGs (Differentially Expressed Genes)를 1,091 (562 up-regulated, 529 down-regulated) 개 선발하였다. 또한 선발된 유전자들의 GO 와 단백질 상호작용 네트워크 분석을 통해 대사, 발달, 스트레스, 면역, 방어 반응에 관련된 주요 브라시노스테로이드 신호전달과 연결된 스트레스 관련 유전자군을 분리하였다. 선발된 유전자중 NB-ARC와 FLS2는 bes1-D 계통이 야생형 En-2 계통에 비해 약 6배 정도의 발현량이 증가되었으며, TIR1, TSA1, OCP3 유전자등은 bes1-D 계통이 야생형 En-2 계통에 비해 발현이 감소되었다. 또한 브라시노스테로이드 활성형 계통이 야생형 식물체 계통에 비해 가뭄 스트레스 및 병원균에 대해 저항력이 향상되었다. 따라서 microarray 분석을 통한 유전자 간 발현 네트워크와 유전체 정보를 결합하여 대단위 주요 기능 유전자들을 동정할 수 있는 방법을 고안하여 실험에 사용하였다. 이를 통해 기능 획득 돌연변이 bes1-D가 식물들이 다양한 스트레스 환경에 적응할 수 있는 반응을 조절한다는 사실을 보여주고 있다.
