  • The purpose of this research is to examine the effect of Simjeongkyeok Sa-am acupuncture treatment for major symptoms of Hwa-byung. Method : In this randomized, single blind, placebo-controlled study, we compared Simjeongkyeok acupuncture with Sham acupuncture in the treatment for major symptoms of Hwa-byung. Likert scale for major symptom of Hwa-byung was measured as the 1st evaluative instrument, and STAXI-K, STAI-K, BDI-K and HRV were also measured as the 2nd evaluative instrument at the before treatment and after treatment. Results : In comparison of Likert scale for major symptoms, total score of after treatment decreased significantly at each point on both groups, but there was no significant difference between both groups. In comparison of STAXI-K, STAI-K, BDI-K, there was no significant difference in variation of score between both groups. But Simjeongkyeok group showed higher ratio variation of STAXI expression than that of Sham group, Also on subjects whose main complaint symptom were burning sensation and whose pattern identification were Qizhi, Simjeongkyeok group showed higher variation of Likert scale score and BDI-K than that of Sham group. The significance was border line around. Conclusion : We considered that Shimjeongkeok treatment will he likely to he recommended for treating Hwa-byung, especially on subjects in each group whose main complaint symptom were burning sensation or whose pattern identification were Qizhi. Also it may also be effective on the management of anger expression.

  • We investigated the effects of distilled Astragali Radix Herbal Acupuncture on autonomic nervous system with the Heart Rate Variability(HRV) in adult man. as well as we tried to observe how distilled Astragali Radix Herbal Acupuncture on the balance of the autonomic nervous system. Methods : We investigated on 61 healthy volunteers consisted of 31 subjects in experiment(distilled Astragali Radix Herbal Acupuncture) group and 30 subjects in control(Normal Saline) group. Study form was a randomized, placebo-controlled, double-blind clinical trial. 31 subjects in experiment group were injected distilled Astragali Radix Herbal Acupuncture at GB21(Kyonjong) and 30 subjects in control group were injected Normal Saline at GB21(Kyonjong). except of 2 subjects(in control group) who can't be measured and 10 subjects(6 in experiment group and 4 in control group) who move or make unforceable error during measuring. Finally 25 subject in experiment group and 24 subject in control group are studied. We measured HRV by PolyG-I on 7 times : before and after injection per 5 minutes during 30 minutes. The SPSS 10.0 for windows was used to analyze the data and the paired t test(in group) and Student t test(between two groups) were used to verify the result. Results : I. After distilled Astragali Radix Herbal Acupuncture injection, SDNN is significantly high from 5 minute to 10 minute and from 15 minute to 30 minute, Complexity is significantly low from 20 minute to 30minute. HRV index is significantly mgb for first 20 minute and from 25 minute to 30 minute, RMSSD is significantly high only from 15 minute to 20 minute. 2. HRV index of distilled Astragali Radix Herbal Acupuncture Group significantly increased from 25 minute to 30 minute, pNN50 of distilled Astragali Radix Herbal Acupuncture Group significantly decreased from 25 minute to 30 minute and RMSSD of distilled Astragali Radix Herbal Acupuncture Group significantly increased from 25 minute to 30 minute compared with those of Normal Saline group. 3. After distilled Astragali Radix Herbal Acupuncture injection, Ln(TP) is significantly high from 5 minute to 10 minute and from 15 minute to 30 minute. Ln(VLF) is significantly high after 5 minute, Ln(LF) is significantly high after 15 minute and Ln(HF) is significantly high from 5 minute to 10 minute and 25 minute to 30 minute, but significantly low for first 5 minute and from 10 minute to 20 minute. Normalized LF is significantly high after 20 minute and Normalized LF is significantly low after 20 minute. Conclusions : The results suggest that distilled Astragali Radix Herbal Acupuncture in healthy adult man tend to activate the autonomic nervous system within normal range. This result is derived from that parasympathetic nervous system was continuously activated and sympathetic nervous system was activated a little later.

  • Objectives This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the stroke patients with Post-stroke Urinary Incontinence(PSUI). Methods Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUI, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions 8 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUI. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as BL23, CV3, SP6, CV4, CV6, ST28, BL28, BL32, GV20, BL22, GV4 or ST36, for 15-30 minutes. 1-150 Hz frequency is suggested if electro-acupuncture treatments is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. There was a moderate evidence to support safety of acupuncture treatment for PSUI. We recommend acu-points of constitutional acupuncture for Sasangin on the healthy side.

  • Objectives: The purpose of this study was to explore the therapeutic mechanism of acupuncture and bee venom acupuncture (BVA) in patients with idiopathic Parkinson's disease (IPD) using positron emission tomography (PET) and arterial spin labeling (ASL). Methods: Patients with IPD who received a stable dose of anti-parkinsonian medication for at least 4 weeks were recruited and randomly divided into one of two groups: treatment and control. The treatment group (11 subjects) received acupuncture and BVA at acupoints, and the control group (9 subjects) received sham acupuncture and normal saline injections at non-acupoints, twice per week for 12 weeks. The patients were examined using PET and ASL at baseline and after the 12-week treatment. In addition, age- and sex-matched healthy subjects without neurological symptoms and history were recruited to compare ASL data of patients with IPD. Results: PET results revealed that striatal dopamine transporter binding increased in each group after 12 weeks. Although the change was larger in the treatment group, the difference was not statistically significant. In ASL results, the treatment group exhibited hyperperfusion in specific regions compared with the healthy control group. After 12 weeks' intervention, hyperperfusion regions were recovered only in the treatment group. In contrast, significant changes were not found in hyperperfusion regions in the control group after 12 weeks. Conclusions: Our findings suggest that the therapeutic mechanisms of acupuncture and BVA in IPD are different from placebo and operate by altering dopamine availability and recovering hyperactivity in cerebral blood flow.

  • Objectives : Clinical character of chronic tension-type headache is bilateral, moderate intensity, persistent and chronic, repeating disease and CTTH is a common prevalent disease, but pathophysiology and likely mechanism remain unclear. It impedes subjective quality of life. The purpose of this research is to examine the effect of sa-am acupuncture method for chronic tension-type headache. Methods : In this randomized, single blind, placebo-controlled study, we compared active acupuncture with sham acupuncture for the treatment of chronic tension-type headache. Volunteers who satisfied the requirements were enrolled in study. Evaluation of chronic tension-type headache was measured by VAS and Headache Disability Inventory(HDI), Six point Linkert Scale before and after treatments. Results : 26 subjects finished study. There were not difference between two groups on age, sex, weight, height, blood pressure, pulse, respiratory rate, Byeonjeung, sunrise of treatment. In change of VAS, there were not difference between two groups on before treatment. Before treatment per visit, VAS of 6th and 7th visit were significantly decreased in active acupuncture(each p=0.039, p=0.008) and were not decreased in sham acupuncture. In change of VAS on a withdrawing needling after treatment, VAS of 1st, 2nd, 6th and 7th visit were significantly decreased in active acupuncture (each p=0.001, 0.038, 0.035, 0.008) and VAS of 2nd, 4th and 5th, 6th visit were significantly decreased in sham acupuncture(each p=0.033, 0.032, 0.035, 0.031). In change of VAS on 2hrs after treatment, VAS of 4th and 5th, 6th visit were significantly decreased in active acupuncture(each p=0.014, 0.023, 0.027) and 5th visit were significantly decreased in sham acupuncture(each p=0.004, 0.009). In change of VAS on 4hrs after treatment, VAS of 4th and 5th, 6th visit were significantly decreased in active acupuncture(each p=0.018, 0.011, 0.015) and 5th, 6th visit were significantly decreased in sham acupuncture(each p=0.020, 0.015). In change of VAS on the next day after treatment, VAS of 3th and 4th and 5th, 6th visit were significantly decreased in active acupuncture(each p=0.032, 0.011, 0.005, 0.012) and 4th, 5th visit were significantly decreased in sham acupuncture(each p=0.001, 0.012). In change of VAS according to a current time(before treatment, after a withdrawing needling, 2hrs, 4hrs, the next day), total score of VAS was decreased more active acupuncture group than sham acupuncture group, but there were no statistical significance compared with sham acupuncture group. In change of HDI score, after treatment was decreased than before treatment in two group, but there were no statistical significance compared with two group. In change of Six point Linkert scale score, after treatment was decreased than before treatment in two group on 6th, 7th visit(active acupuncture 6th 7th each p=0.002, 0.003, sham acupuncture 6th 7th each 0.003, 0.009), but there were no statistical significance compared with tow group. Conclusion : Sa-am acupuncture treatment is effective to improve the symptoms and quality of life in patients with chronic tension-type headache.

  • Background: Through search the possible randomized control trials, we make a renewed meta-analysis in order to assess the impact of aspirin in preventing the recurrence of colorectal adenoma. Materials and Methods: The Medicine/PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Chinese biomedical literature service system (SinoMed) databases were searched for the related randomized controlled trials until to the April 2016. Three different authors respectively evaluated the quality of studies and extracted data, and we used the STATA software to analyze, investigate heterogeneity between the data, using the fixed-effects model to calculate and merge data. Results: 7 papers were included the renewed meta-analysis, among these studies, two pairs were identified as representing the same study population, with the only difference being the duration of follow-up. Thus there were only five papers included our meta-analysis, and one Chinese paper were also included the work. Results were categorized by the length of follow-up, different kinds of people, varied dose of oral aspirin. The relative of adenoma in patients taking aspirin vs placebo were 0.73 (95% CI 0.55-0.98, P=0.039) with 1 year follow up; 0.84 (95% CI 0.72-0.98, P=0.484) with greater than 1 year follow up; for the advanced adenoma, the RR 0.68 (95% CI 0.49-0.94, P=0.582),for one year; RR=0.75 (95% CI 0.52-1.07, P=0.552) for greater one year. Furthermore the white population could divided into two subgroups according to the different length of follow-up time. When the length of follow-up time less than 3-year, The RR of two subgroups respective were RR=0.86 (95% CI 0.76-0.98, P=0.332), $I^2=0%$, RR=0.68 (95% CI 0.47-0.98, P=0.552), $I^2=64.6%$, But with the extension of follow-up time greater than 2-year, with the white, oral aspirin without considering dose had no efficacy on preventing the recurrence of any adenoma, the RR was 0.86 (95% CI 0.71-1.05, P=0.302), $I^2=16.4%$. Conclusions: This meta-analysis indicated that oral aspirin is associated with a remarkable decrease in the recurrence of any adenoma and advanced adenomas in patients follow-up for 1 year without concerning the dose of aspirin, but with the extension of follow-up time for greater than 1 year, oral aspirin can be effective on preventing the recurrence of any adenoma, but for the advanced adenoma, the result indicated that oral aspirin had no efficacy, According to the inclusion of ethnic groups, we also divided relevant papers into two subgroups as the yellow and white group. Then the follow-up time was less than 3 years, oral aspirin without considering the dose, had an significant efficacy on preventing the recurrence of any adenoma. But with the follow-up greater than 2 years, oral aspirin had no effect in the white.

  • 본 연구 목적은 제2형 당뇨병 환자에서의 D-chiro-inositol(DCI)의 혈당강하 효과, 당뇨 자가관리(Summary of Diabetes Self-Care Activities, SDSCA) 및 삶의 질(SF-36 Version 2.0, Korean)에 미치는 요인을 파악하고자 하였다. 연구대상은 충남대학교병원 내분비대사내과에 내원한 제2형 당뇨병 환자 중에서 3제의 경구 혈당강하제를 12주 이상 투여 했음에도 불구하고 당화혈색소 7.0% 이상인 환자를 2015년 3월부터 2016년 5월까지 24주간 무작위 이중맹검 위약대조 임상시험으로 총 46명을 분석하였다. 연구결과, 실험군에서 DCI 투여 이후 당화혈색소 $8.75{\pm}0.79%$(베이스라인), $8.36{\pm}1.03%$(투여 12주), $8.65{\pm}0.81%$(투여 24주)으로 유의하게 감소하였으나(p<0.05), 대조군과의 변화량은 차이가 없었다. 흥미롭게도 실험군과 대조군에서 당뇨 자가관리 점수가 높아졌으며, 특히 실험군 변화량에서의 하부영역인 혈당검사 만이 유의한 차이를 보였고, 삶의 질은 투여 전 $73.05{\pm}16.85$점에서 투여후 $82.74{\pm}10.68$점으로 향상되었다. DCI 투여에 따른 실험군에서의 요인간 경로분석에서 공복 혈당 변화량은 당뇨 자가관리 변화량이 높을수록(${\beta}=-0.505$, t=-2.743) 높다고 확인되었다. 삶의 질 변화량에 가장 큰 영향을 준 변수는 공복 c-펩타이드 변화량이 높을수록(${\beta}=-0.445$, t=-2.668), 당뇨 자가관리 변화량이 높을수록(${\beta}=0.411$, t=2.024) 높은 것으로 확인되었다. 결론적으로 제2형 당뇨병 환자에게 DCI 투여는 투여 12주차에 혈당 강하 효과를 보이고, 24주차에는 없었지만, 혈당강하 효과는 환자의 당뇨 자가관리를 높이고 삶의 질을 향상시켰다. 본 연구에 기초하여 결과적인 지표와 제2형 당뇨병 환자의 주관적인 관점에서 평가될 수 있는 삶의 질에 대한 경로분석을 통하여 모형의 적합도에 관한 연구로써 그 의의가 있다고 본다.

  • 목 적 : 영아 산통은 잘 설명되지 않는 울음을 특징으로 하는, 소아과 의사가 자주 접하는 문제 중의 하나로서, 환아 및 가족 구성원 모두에게 심각한 고통을 안겨준다. 최근의 보고에서 경구로 투여된 sucrose가 어린 영아에게 진통 효과가 있고 이러한 진통 효과가 영아 산통의 치료에도 효과가 있다고 보고하였다. 저자들은 sucrose가 주성분이면서 일상생활에서 흔히 얻을 수 있는 설탕이 영아 산통의 치료에 있어서도 진통 효과를 나타내는 지를 알아보기 위하여 본 연구를 시도하였다. 방 법 : 부산 대동병원 응급실 및 외래 방문한 환아들 중 영아 산통을 가지고 있는 건강한 4-12주의 만삭아를 대상으로 삼았다. 보호자들에게는 적절한 설명과 교육이 이루어졌고, 각 군은 증상이 발생시에 10% 설탕물 2 mL 혹은 증류수 2 mL를 각각 투여하였다. 보호자는 하루 당 총 울음시간, 자정과 오전 6시 사이에 울면서 일어나는 횟수, 투약 후 울음이 그칠 때까지의 시간, 다른 증상의 발현 유무를 포함한 부모의 주관적인 판단에 기초한 5단계의 영아 산통 호전 점수가 기록되어있는 7일간의 보호자용 달력이 제공되었다. 모든 자료는 보호자용 달력과 면담을 통해 분석되었고, 면담자에겐 그 환아가 속해있는 군에 대해서 어떤 정보도 주어지지 않았다. 결 과 : 1주일간의 치료 후 자다가 깨어나는 횟수 변화의 있어서는 설탕군에서 $-1{\pm}1.2$회, 대조군에서 $0.47{\pm}1.07$회로 유의한 차이가 나타나지 않았다. 그러나, 하루 중 총 우는 시간의 변화에서 설탕군은 $-1.58{\pm}1.43$시간, 대조군은 $-0.65{\pm}1.27$시간(P=0.045) 이었으며, 영아 산통 호전 점수에 있어서도 설탕군에서 $1.26{\pm}1.24$, 대조군에서 0.41${\pm}0.80$(P=0.019)로 설탕군에서 대조군에 비해 통계적으로 의미 있게 나타났다. 설탕군내에서 부모가 증상 호전이 있다고 대답한 11명의 환아와 그렇지 않은 8명의 환아들간의 나이에 따른 비교에서, 효과를 보인 군은 $45.67{\pm}7.49$일, 효과를 보이지 않은 군은 $55.75{\pm}10.44$일(P=0.038)일로 나이가 어릴수록 설탕에 대한 동통 감소 효과가 큰 것으로 나타났다. 결 론: 이상의 연구에서 영아 산통을 가진 환아에게 단순히 설탕물을 투여하는 것만으로도 통증 감소에 효과가 있는 것으로 생각되며, 좀더 체계적이고 과학적이며 광범위한 연구가 필요할 것으로 생각된다.

  • 본 연구에서는 혈전생성을 촉진시키는 주요 원인 중 하나인 흡연하는 30세 이상 60세 이하의 건강한 남성 92명(위약 캡슐군 43명, OPE캡슐군 49명)을 대상으로 양파껍질 추출물(OPE)의 섭취가 항혈전 체계에 긍정적인 영향을 미치는지 그 효과를 검증하고자 시행되었다. 위약-대조군 연구디자인을 통해 OPE를 캡슐 형태로 제조하여 10주간 하루 2회 2캡슐씩 10주간 제공하였다(하루 섭취분량 내 100 mg quercetin 함유). OPE캡슐군과 위약캡슐군 각각의 평균 연령은 $46.1{\pm}7.1$세, $42.4{\pm}8.2$세로 전체 대상자들의 평균 연령은 $44.4{\pm}7.8$세였으며, 연구대상자들의 하루 흡연량은 위약 캡슐군과 OPE캡슐군에서 모두 하루 '20~29개피'의 담배를 피우는 비율이 가장 높은 것으로 나타났다. 체지방과 비만도는 과체중 범위에 속하고 있었으며, 두 군간 임상시험 전후에 유의적인 차이는 없었다. 혈액학 및 생화학적 지표 특성중 HB, RBC, WBC, MCH, RDW, PDW는 임상시험 전후에 유의적인 차이는 없었으나, 혈소판 수는 두 그룹 모두에서 유의적으로 감소(p<0.01), 총 철결합 능(위약캡슐군 p<0.001, OPE캡슐군 p<0.001)과 불포화 철결합 능(위약캡슐군 p<0.001, OPE캡슐군 p<0.01)은 두 그룹 모두 유의적으로 증가하였다. 항혈전 지표에서는 OPE캡슐군에서 10주 후 prothrombin time(PT)(p<0.01)과 activated partial thromboplastin time(aPTT)(p<0.001) 모두 유의적으로 연장되었다. aPTT는 BMI, 체지방 %, 허리둘레와 유의적인 상관성을 보이지 않았지만, PT의 경우 BMI(r=-0.321, p<0.01), 체지방 %(r=-0.375, p<0.001), 허리둘레(r=-0.318, p<0.01)와 유의적인 음의 상관관계를 보였다. 이상과 같이 본 연구에서 OPE캡슐의 섭취는 항혈전 효과가 있음이 확인되었다. 비록 본 연구대상자들이 일부 사무직 위주의 흡연자이고 10주간의 짧은 기간이었다는 단점이 있지만, 별도의 식생활 변화없이 본 시료 섭취만으로 혈액응고시간을 유의적으로 지연시켰다는 점에서 폐기되는 양파껍질의 활용 가능성을 보여 주었다고 사료된다. 앞으로 보다 폭넓은 피험자를 대상으로 한 장기간의 임상시험을 통해 우리나라 국민의 주 사망원인인 과도한 혈전형성으로 인한 혈관계 질환의 감소에 도움을 줄 수 있기를 기대해 본다.
