유기염소계 살충제 endosulfan과 이의 토양 중 주 분해산물인 endosulfan sulfate의 ZVI에 의한 분해정도와 분해산물을 조사하였다. ZVI처리에 의해서 수용액내에서 endosulfan과 endosulfan sulfate는 pH가 낮을수록 분해율이 높았으며 pH 3.0에서 α-endosulfan은 28%, endosulfan sulfate는 90%정도 분해되었고 acetone/water(50/50, v/v) 용액에서는 α-endosulfan은 65%, endosulfan sulfate는 92%정도 분해되었다. ZVI에 의해 α-endosulfan 및 endosulfan sulfate는 분해되어 2개의 미확인 물질을 생성하였다. 반응시간에 따른 반응속도와 반감기를 비교해 보면 endosulfan sulfate가 α-endosulfan에 비해 빠르게 분해되는 양상을 보였다. ZVI의 처리에 인해 α-endosulfan과 endosulfan sulfate에서 생성된 2개의 미확인 물질은 GC-MS로 분석한 결과, 하나의 Cl-가 H+로 치환된 구조이성질체로 나타났다. The dechlorination of endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepine-3-oxide) and its metabolite, endosulfan sulfate via reaction with zerovalent iron under various pH conditions was studied using aqueous solution. The reaction products, which were probably produced from endosulfan and endosulfan sulfate by ZVI were identified by GC-MS. The lower the pH of reaction solution, the higher the transformation rate of endosulfan and endosulfan sulfate. The transformation rates of endosulfan and endosulfan sulfate in pH 3.0 by ZVI were 28% and 90% but those of endosulfan and endosulfan sulfate in mixture solution of water/acetone were 65% and 92%, respectively. The pH of reaction solution after ZVI treatment was increased to pH 10. Endosulfan was hydrolyzed at pH 10 but endosulfan sulfate was not hydrolyzed. Two unknown peaks were produced from endosulfan sulfate by treatment of ZVI. As a result of GC-MS analysis, unknown peaks were guessed to be structural isomer substituted hydrogen for chlorine.

The purpose of this study is to report a patient with pleural effusion improved by oriental medical treatment. The patient was treated with Bokryunghaengingamcho-tang and acupunture. We measured pleural effusion by Chest CT, twice a month. Pleural effusion decreased in Chest CT after oriental medical treatment. This study suggests that Bokryunghaengingamcho-tang is effective in pleural effusion.

본 연구는 정수처리공정에서 사용하는 염소소독으로 취급이 용이하며, 기존 액화염소를 대체할 수 있는 현장발생형 고농도 차아염소산나트륨 발생장치를 국산화 개발하는 것이다. 이 장치는 포화소금물을 이용한 전기화학적 특성으로 고농도(12%)의 차아염소산나트륨을 생성하는 것으로, 저농도(0.8%)의 차아염소산나트륨 발생장치보다 전류효율 38.7 % 높이고, 소금사용량 54.6 %와 클로레이트 함량 97.3%을 저감하는 장치이다. The purpose of this study is to replace existing liquid chlorine with localization of on-site high (12%) sodium hypochlorite generation system. On-site high (12%) sodium hypochlorite generation system is higher the current efficiency of 38.7%, 54.6% reduction of salt consumption, and 97.3% lower rate of chlorate than on-site low (0.8%) sodium hypochlorite generation system.

Urinary disturbance is deficit in volitional control of voiding. Stroke can cause temporary or permanent urinary disturbance. The purpose of this study was to confirm the effect of Jasin-hwan on urinary disturbance as heat syndrome. This study was carried out on 3 patients with urinary disturbance caused by stroke. We measured components of IPSS (international prostate symptom score) at pre-treatment and post-treatment. After prescribing medication to the patients, symptoms improved rapidly within three weeks. These results support that Jasin-hwan is effective in reduction of urinary disturbance as heat syndrome.

Objective: This study reviewed experimental studies on the effects of Korean medical treatment for diabetes mellitus (DM). Method: We reviewed 24 studies about DM that had been published since 2013. We searched the Korean Institute of Oriental Medicine (KIOM) database with the keyword '당뇨', '消渴', 'Diabetes'. Results: 1. The studies used various Korean medicine treatments; 15 used single medicinal herbs, 6 used herbal complexes, and 2 used acupuncture. 2. The measurement parameters used in the studies included blood glucose, body weight, histochemical change, lipid parameters, and food/water intake. Anti-diabetic effects were demonstrated in most of the studies. 3. The experimental animals used were rats or mice. There were 15 type 1 diabetes models, 7 type 2 diabetes models, and one normal model. Among them, 13 cases of chemical diabetes induced by Streptozotosin (STZ, type 1 diabetes inducer) were the most common. Conclusion: Further articles on Korean medical treatment of DM should be studied.

Objectives: This study evaluated the effects of traditional Korean medicine treatment on a patient with asthma. Methods: A patient was treated with acupuncture, herbal medicine, and cupping. The effect of treatment was evaluated via the quality of life questionnaire for adult Korean asthmatics (QLQAKA), the visual analog scale (VAS), and night awakening frequency. Results: After treatment, improvements were observed. The total QLQAKA score increased from 36 to 50. Conclusions: This study observed that traditional Korean medicine treatments are effective in caring for a patient with asthma.
