  • Objective : Globus pallidus interna (GPi) is acknowledged as an essential treatment for advanced Parkinson's disease (PD). Nonetheless, the neurotransmitter study about its results is undiscovered. The goal of this research was to examine influences of entopeduncular nucleus (EPN) stimulation, identical to human GPi, in no-lesioned (NL) rat and 6-hydroxydopamine (6-HD)-lesioned rat on glutamate change in the striatum. Methods : Extracellular glutamate level changes in striatum of NL category, NL with deep brain stimulation (DBS) category, 6-HD category, and 6-HD with DBS category were examined using microdialysis and high-pressure liquid chromatography. Tyrosine hydroxylase (TH) immunoreactivities in substantia nigra and striatum of the four categories were also analyzed. Results : Extracellular glutamate levels in the striatum of NL with DBS category and 6-HD with DBS category were significantly increased by EPN stimulation compared to those in the NL category and 6-HD category. EPN stimulation had no significant effect on the expression of TH in NL or 6-HD category. Conclusion : Clinical results of GPi DBS are not only limited to direct inhibitory outflow to thalamus. They also include extensive alteration within basal ganglia.

  • This study carried out to analyze the characteristics of water concentration for Saemangeum reclaiming area during two seasons. Total nitrogen appeared by thing which all mean values are the biggest at two survey at ST.4 that is near with Mangyoung river. At the same time, change by range of tide was seen. Therefore, is thought that ST.4 suffers impact of river and seawater at the same time. But is thought that water of Mangyoung river exerts bigger effect than seawater because ST.4 appears that concentration is high clearly with different Sampling point. Therefore, is thought that pollution occurs better than different sampling point if ST.4's flowing deters.

  • The effects of electroacupuncture on gastric motility in dogs were investigated in this study. The acupoints used in this experiment were Zu San Li (ST-36), Feng Long (ST-40), Jie Xi (ST-41), and Li Dui (ST-45) which belong to stomach meridian, Wei Shu (BL-21) which belongs to urinary bladder meridian, and Zhong Wan (CV-12) which belongs to conception vessel meridian. The animals were stimulated with 2-4 volt and 5 Hz for 20 min. Electroacupuncture at Zu San Li and Wei Shu acupoint increased the gastric motility, but Zhong Wan decreased the motility. There were no change in gastric movement after electrostimulation at Feng Long, Jie Xi and Li Dui acupoints. It was considered that electroacupuncture at Zu San Li and Wei Shu acupoints to promote the gastric movement, and at Zhong Wan acupoint to depress the movement might be effective in veterinary practice.

  • Recently IPCC (International Panel on Climate Change, 2007) pointed out that global warming is a certain ongoing process on the earth, due to which water resources management is becoming one of the most difficult tasks with the frequent occurrences of extreme floods and droughts. In this study we made runoff predictions for several control points in the Geum River by using the watershed runoff model, SSARR (Streamflow Synthesis and Reservoir Regulation Model), with daily RCP 4.5 and RCP 8.5 scenarios for 100 year from 1st Jan 2006 to 31st Dec 2100 at the resolution of 1 km given by Climate Change Information Center. As a result of, the Geum River Basin is predicted to be a constant flow increases, and it showed a variation in the water circulation system. Thus, it was found that the different seasonality occurred.

  • Objective: Purpose of this study was to examine the effect of electroacupuncture(EA) at Xingjian(LR2) as 'Fire(火)' point of The Leg Absolute Um Liver Meridan(足厥陰肝經 : Chok-Kworum-Kan-Kyong) on the facial thermal change. Methods: Subjects of this study were 15 patients with upperpart(includes head and facial part) fever of human body and two examinations were carried out in each other day. We divided cases of two examinations into two groups. One is experimental group(N=15) that was carried out electroacupuncture stimulation at Xingjian(LR2), the other is control group(N=15) which was carried out electroacupuncture stimulation at optional point(in space between 1st and 2nd fingers) except acupuncture points of 12 meridians. We took the temperature of fixed areas on face by digital infrared thermal image(D.I.T.I.) before and after electroacupuncture stimulation. Those fixed areas on face that was taken temperature are Jingming(BL1), Sibai(ST2), Dicang(ST4), Indang, Shuigou(GV26), Chengjiang(CV24) areas. In cases of temperature of Jingming(BL1), Sibai(ST2), Dicang(ST4) areas, we applied each mean of left and right temperature to statical analysis. Results: In the group of electroacupuncture stimulation at Xingjian(LR2), temperature of every fixed areas on face fell: Jingming(BL1) area's ${\Delta}T=-0.7007{\pm}0.78642$, Sibai(ST2) area's ${\Delta}T=-0.6280{\pm}0.56439$, Dicang(ST4) area's ${\Delta}T=-0.5940{\pm}0.60179$, Indang area's ${\Delta}T=-0.7200{\pm}0.64515$, Shuigou(GV26) area's ${\Delta}T=-0.6160{\pm}0.80487$, Chengjiang(CV24) area's ${\Delta}T=-0.5627{\pm}0.72615$. In Xingjian(LR2) electroacupuncture group, each temperature of Jingming(BL1), Sibai(ST2), Indang areas showed a drop significantly in comparison with control group (p<0.05). But each temperature of Dicang(ST4), Shuigou(GV26), Chengjiang(CV24) areas did not showed a drop significantly in comparison with control group(p>0.05). Conclusions: The results mentioned above showed that electroacupuncture stimulation at Xingjian(LR2) significantly decreased the temperature on face of patients with upperpart fever of human body. In Xingjian(LR2) electroacupuncture group, especially temperature of upper part of face includes eye, cheekbone, forehead regions showed a drop significantly in comparison with control group.

  • A 47-year old man visited our hospital because of purulent sputum for 3 months. Chest X-ray showed destruction of both the upper lungs, and bronchoscopy revealed inflammatory change with whitish plaque on the left main bronchus through upper division of the left upper lobe. Tracheobronchial aspergillosis (TBA) was finally diagnosed as a result of histologic and microbiologic examination. However, he went abroad without medication before the diagnosis was made and visited again 10 months later. Follow-up bronchoscopy showed complete regression of the previously noted endobronchial lesion. We describe this case to consider the role of antifungal treatment in immunocompetent hosts, as well as to discuss a rare condition; TBA resolved spontaneously.
