Purpose : This study was performed to evaluate the effects of magnetic therapy (MT) on pain threshold, blood flow, and balance in patients with knee osteoarthritis. Methods : A single-blind, randomized controlled trial (RCT) was conducted with 30 patient with knee osteoarthritis. They were randomly allocated 2 groups; magnetic therapy group (MTG; n=15) and placebo magnetic therapy group (PG; n=15). The MTG group received 30 minutes magnetic therapy and 20 minute conservative physical therapy (Hotpack, ICT), magnetic therapy was conducted in magnetic therapy device (OM-100, NUGA, Korea). In the placebo magnetic group received 30 minutes placebo magnetic therapy and 20 minute conservative physical therapy. Each group performed 50 minutes a day 3 times a week for 8 weeks. The primary outcome pressure pain threshold test, blood flow, balance ability were measured by a pressure threshold meter (Commander algometer, JTECH medical, USA), laser dofler image (Moor LDI2-IR, Moor instruments, USA), balance measurement system (BioRescue, Marseille, France). The measurement were performed before and after the 8 weeks intervention period. Results : Both groups demonstrated significant improvement of outcome in pain threshold, blood flow, and balance ability during intervention period. magnetic therapy group revealed significant differences in pain threshold, blood flow, and balance as compared to the placebo magnetic therapy group groups (p<.05). Our results showed that magnetic therapy was more effective than placebo therapy on pain threshold, blood flow, and balance in patients with knee osteoarthritis. Conclusion : Our findings indicate that magnetic therapy can improve pain threshold, blood flow, and Balance, highlight the benefits of magnetic therapy. This study will be able to be used as an intervention data for recovering pain threshold, blood flow, and balance in patients with knee osteoarthritis.

Purpose: To evaluate thermal effect and medication compliance of red ginseng extract. Methods: Randomized, double-blind, placebo-controlled, cross-over clinical study was performed. Twenty four healthy, married women aged 30-45 years with FSFI score below 25 were randomly divided into two groups; red ginseng group(N=12) and placebo group(N=12). During the first 6-week period (Study1), each group was dosed with red ginseng or placebo twice a day. Before starting the second 6-week period(Study2), a crossover design was chosen with a 2-week break(Washout period). Interchanging two groups after Washout period, red ginseng and placebo were dosed to each group. The efficacy of thermal effect was measured with subjective warm sensation scale and lower abdomen temperature by Digital Infrared Thermographic imaging(DITI) before and after each 6-week period. A medication compliance was assessed after each 6-week period and the correlation medication compliance between Sasang Constitution and subjective warm sensation was analyzed. Results: Overall 23 participants completed the study. In subjective warm sensation scale, after taking placebo, all participants exhibited an improving trend, but there was no significant difference. In lower abdomen temperature by DITI, statistically significant objective thermal effect of red ginseng was also not shown. A medication compliance was higher in Yin constitution(Taeumin, Soeumin), and showed an upward trend with decreasing subjective warm sensation. But no statistically significant difference was exhibited. Conclusion: Statistically significant thermal effect of red ginseng was not shown in this study. We anticipate if a long-term clinical trial is practiced, significant thermal effect of red ginseng will be shown.

The purpose of this thesis is to investigate whether taurine supplementation in combination with fructose improves both energy metabolism and exercise capacity. Eight collegiate female subjects were recruited for the study. Each subject went through threecross-over designs: control(fluid), fructose, and taurine plus fructose supplementation trials. Subjects received taurine supplementation 100 mg/kg a day for two weeks. After the supplementation, all subjects take 10% fructose at 15 min prior to exercise, immediately before exercise, and every 15 min during exercise. Subjects received 150 ml fluid as placebo during the same procedure. The subjects performed submaximal exercise at the exercise intensity of 60% for 45 min and then 80% of maximal oxygen uptake (VO_2max) until exhaustion time. A 10ml blood sample was taken for measuring the level of glucose, ammonia, lactate, free fatty acids, and insulin every 15 min during exercise at 60% of VO_2max. The blood glucose levels was significantly higher at 45 min and 50 min exercise after supplementation of fructose, and immediately before exercise and 50 min exercise after taurine plus fructose compared to the placebo trial. However, the values tended to be lower in taurine plus fructose supplementation compared to the fructose trial. The levels of both lactate and ammonia were significantly lower compared to the placebo, while the exhaustion time was significantly increased. The level of free-fatty acids was significantly lower at 30, 45, and 50 min after fructoseand fructose plus taurine supplementation compared to the placebo trial. The level of glucagon was significantly lower at 15, 30, 45, and 50 min after fructose and fructose plus taurine supplementation compared to the placebo trial. There was no differences in insulin concentration among three treatments. This thesis concludes that combined taurine and fructose supplementation prior to exercise may improve exercise tolerance time and energy metabolism, lowering the muscle fatigue factors such as lactate and ammonia.

The purpose of this study was to examine the effect of supplementary highly purified chitosan (HPC) on blood alcohol concentration in healthy human. The human study was performed with two sections. Each section of the study was conducted by two-phase cross-over design with a week wash-out period. All volunteers took HPC in one phase, and took a placebo in the next phase. Blood alcohol concentrations were different between in those taking HPC and in those taking the placebo in the human. And the concentration of serum aspartate aminotransferase (AST, GOT) and alanine aminotransferase (ALT, GPT), the indicator of liver cell damage, was lowered in those taking HPC, compared to those taking the placebo. In conclusion, taking HPC prior to drinking alcohol can somewhat reduce alcohol concentration in human blood and liver cell damage.

The effects of disulfiram implantation therapy have three components : placebo, pharmacological, and psychological effects, However, considering the fact that there is no reported DER(disulfiram-ethanol reaction) in placebo implanted patients and the absorption of implanted disulfiram is not sufficient to produce DER, the major effect of disulfiram implantation is psychological rather than placebo and pharmacological one, Recently, there have been great efforts to develop a new farm of disulfiram which could exert a real pharmacological effect through the heightened bioavailability, To illustrate several examples, there are copolymer consisting of disulfiram and polymer such as polyethylene glycol and PLGA(polyglycolic-co-L-lactic acid) and depot in which disulfiram is dissolved into saline solution containing 5% w/v carboxymethylcellulose or 0.1% polysorbate 80. On the other hand, there has been a continuous research about Me-DTC, an active metabolite of disulfiram, which inhibit ALDH (acetaldehyde dehydrogenase) more potently even at a smaller amount than disulfiram. In the future. In is hoped to develop a new form of disulfiram with high bioavailability at a small amount.

At the conclusion of a double-blinded, randomized clinical trial of propranolol hydrochloride, but before un blinding, the patients and clinic personnel were asked to guess the treatment group assignment of each patient. While 79.9% of the patients receiving propranolol correctly Identified their treatment group assignment, 57.2% of the patients receiving placebo incorrectly guessed that they were aiso in the propranolol group. No specific mechanism was identified to explain why more patients receiving propranolol were better able to guess' their group assignment. Clinic physicians correctly identified the group assignment of 69.9% of the patients receiving propranolol and 68.8% of the patients receiving placebo. Clinic coordinators correctly identified the group assignment of 67.1% of the patients receiving propranolol and 70.6% of the patients receiving placebo. For clinic personnel, heart rate level and heart rate change seem to be the mechanisms employed to Identify their patients' treatment assignment.

본 연구에서는 해설판의 '숲의 명칭' 또는 '숲의 치유 효과에 대한 정보'가 이용객의 회복환경지각(perceived environmental restorativeness: PER)과 전반적 치유효과지각(perceived healing effectiveness: PHE)에 미치는 영향을 조사하였다. 2015년 5-6월 중 연구대상지역인 무등산국립공원 내 '치유의 숲길' 방문객을 대상으로 편의표본추출 방법을 통해 247명의 표본이 선정되었으며 자기기입식 설문지기법을 통하여 데이터 수집이 이루어 졌다. 본 연구의 실험을 위해 '치유의 숲길'을 따라 설치한 해설판(숲의 명칭과 치유의 숲길의 치유효과에 관한 내용 포함)을 읽은 응답자는 플라시보그룹, 해설판을 읽지 않은 응답자는 컨트롤그룹으로 간주하였다. 분석결과, 컨트롤과 플라시보그룹 간 PER과 PHE는 전반적으로 차이가 없는 것으로 나타났다. 그러나 PER의 구성 요인별 비교 결과에 따르면 플라시보그룹이 '벗어남'(being away) 요인에서 컨트롤그룹에 비해 긍정적인 수치를 나타냈다. PER의 4개 요인(벗어남, 짜임새, 매혹감, 적합성) 모두 PHE에 영향을 미치는 것으로 조사되었으며(P<0.001) 이들 4개 요인은 PHE의 51.1%를 설명하였다. PHE에 미치는 영향력은 짜임새, 벗어남, 적합성, 매혹감 순으로 크게 나타났다. PER에 미치는 플라시보 효과는 남성, 저연령층, 저 방문경험 그룹에서 나타났으며, PHE에 미치는 플라시보 효과는 남성, 소그룹, 혼자서 또는 친척/가족 동반그룹, 저 방문경험 그룹에서 발견되었다. 관리적 관점에서 몇 가지 시사점을 제시하였다.
