침구의학 임상실습에서 한의과대학 학생의 기대도와 만족도 분석

선창우, 김민정 상지대학교 한의학연구소 2022 尙志韓醫論文集 Vol.10 No.1

Objectives : The purpose of this study is to analyze expectation and satisfaction with clinica1 training in the department of Acupuncture and Moxibustion. Methods : A survey was conducted with 57 students who completed a clinical training in 2020. After completing the course of Objective Structured Clinical Examination(OSCE), Clinical Performance Examination(CPX), medical observation, presentation and discussion class, they filled out the questionnaire containing 17 questions. We investigated prior expectations, satisfaction, usefulness and learning environment. Also, we asked about the good points and points of improvement in clinical training of department of acupuncture and moxibustion. Results : 1. Students have higher expectations for clinical training in department of acupuncture and moxibustion than overall hospital clinical training. They have high expectations for attending clinics, observing patients, and clinical skills. 2. Although it had a positive effect on treatment ability and ethical attitude, relatively low effect on team activity and interaction. 3. Although satisfaction with treatment participation and acupuncture support was high, interaction with other medical co-worker and observing patients were relatively low. 4. The most satisfactory points were medical observation, observing patient, and various learning methods, and lacking points were practice time. Conclusions : Clinical training in the department of acupuncture and moxibustion can be highly estimated from the viewpoint of expectation and satisfaction.

델파이 기법을 활용한 퇴행성 관절염 (고관절·수지관절염)에 관한 한의표준임상진료 지침 개발

선창우, 김민정 상지대학교 한의학연구소 2023 尙志韓醫論文集 Vol.11 No.1

Objectives: The purpose of this study is to report the results of conducting a survey of experts using the Delphi technique. Methods: We developed recommendations for various korean medicine treatment techniques including acupuncture treatment and herbal medicine. Based on the developed draft, we utilized a two-round delphi process with panel of 8~9 experts for their level of agreement. Results: 1. Manual acupuncture for degenerative arthritis (hip and hand) is effective in relieving pain and improving function. 2. Performing combined korean medicine treatment (manual acupuncture, electroacupuncture, and bee venom therapy) for patients with degenerative hip arthritis is more effective in relieving pain and improving function compared to performing conventional korean-western medicine treatment. 3. Bee venom therapy for patients with degenerative hand arthritis is effective in relieving pain and improving function compared to conventional korean-western medicine treatment. Conclusions: Through this study, clinical questions were ultimately proposed for patients using a literature review and the Delphi method to develop standard korean medicine clinical practice guideline for degenerative hip arthritis and digital arthritis.

한윤지,선창우,우연주,이동혁,서진우,유준상,김주희,권보인 대한예방한의학회 2023 대한예방한의학회지 Vol.27 No.2

Objectives : Sojadodamgangki-tang and its main components are traditional korean medicinal methods for treatment of cough, sputum and dyspnea. Using a respiratory inflammatory model, we intend to reveal the anti-inflammatory effect and its immune mechanism of Sojadodamgangki-tang. Methods : We used a papain-induced respiratory inflammatory mouse model. 8-week-old female BALB/C mice were divided into 3 groups as follows: the following groups: saline control group, papain treated group (vehicle), papain and Sojadodamgangki-tang (200 mg/kg) treated group(n=4). To evaluate the anti-inflammatory effect of Sojadodamgangki-tang extracts, inflammatory cell infiltration was measured in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). In addition, the effects of Sojadodamgangki-tang extracts on Th2 cell population in lung were determined by using flow cytometry. Results : Sojadodamgangki-tang extracts administration reduced inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, total immunogloblin (Ig)-E levels was reduced in BALF and serum by drug administration. Interestingly, Sojadodamgangki-tang extracts treatment also decreased the Th2 cell (CD4+ GATA3+ ) population in lung. Conclusions : Our findings indicate Sojadodamgangki-tang extracts have anti-inflammatory effects by mediating Th2 cell and B cell activation.

섬유근통증후군에 대한 수기치료의 효과: 체계적 문헌고찰 및 메타 분석

안정훈,선창우,김병준,박인화,차윤엽 척추신경추나의학회 2023 척추신경추나의학회지 Vol.18 No.1

Objectives : This review was conducted to investigate the evidence of efficacy of manual therapy for fibromyalgia syndrome (FMS). Methods : We searched 10 electronic databases (CAJ [CNKI], CINAHL, Cochrane Library, Embase, PubMed, Web of Science, DBpia, KISS, RISS, and OASIS) to find randomized-controlled clinical trials (RCTs) investigating manual therapy for FMS. Visual Analogue Scale (VAS) and score in the Fibromyalgia Impact Questionnaire (FIQ) were analyzed as the main evaluation criteria. Results : Among 273 articles, 254 were screened and 19 RCTs were selected. Only 17 RCTs could be statistically analyzed. Manual therapy was more effective than placebo or sham or no treatment in terms of VAS (p=0.0003). When combined with medication or exercises, manual therapy showed therapeutic effect in terms of reducing pain (VAS) and ameliorating symptoms of FMS (FIQ). However, manual therapy did not show its effect in terms of VAS compared to medication. Lastly, there were no significant difference between manual therapy and exercise in terms of improvements in VAS and FIQ. Conclusions : Effectiveness of manual therapy including CMT for treating FMS was identified. However, this study has its limitations due to the small size and number of RCTs that were included in this study. Nevertheless this study could be a groundwork for well-designed research for CMT for FMS.

전자발생장치(EPA)를 이용한 전자와 항산화 현상과의 상관관계에 대한 예비 연구

이동현(Dong-Hyun Lee),선창우(Chang-Woo Seon) 한국물리학회 2024 새물리 Vol.74 No.3

이 연구의 목적은 전자발생 장치를 통해 주사되는 전자의 체내에서의 역할, 특히, 신체의 산화환원 반응에 대한 연관성을 보고자 함이다. 질병의 시작은 혈액내 산염기 대사의 변화와 직접적으로 관련이 있다. 여러 요인에 의해 혈액내 산염기대사의 균형이 깨지면서 각 장기를 이루는 세포와 조직의 대사장해로 염증이 생기게 되고 이것이 반복되면 질병이 생기게 된다. 이 이론에 기초하여 산염기 대사균형을 조절하는 장치를 개발하여 효과 검증이 필요하였다. 이 연구는 소규모로 조사 대상에 대해 연구실험해보는 선행연구에 바탕을 두고 있다. 피실험자의 소변, 혈액을 이용하여 수소이온 농도와 산화환원 전위를 각각 측정했다. 이 장치는 음전자를 발생시켜 경피를 통해 혈액내로 진입하여 체내 대사후 생긴 산화 물질내의 수소이온 농도와 결합하여 수소원자로 변환시켜 환원효과를 가진다고 본다. 이 연구를 기반으로 향후 신체의 질병 상태와 산화환원 상태와의 연관성에 대한 많은 연구가 진행될 것으로 보인다. The aim of this study was to evaluate the correlation between electrons injected through an electron producing apparatus (EPA) and redox reactions of human body. The onset of the disease is directly related to changes in acid-base metabolism in the blood. When the balance of acid-base metabolism in the blood is broken due to various factors, inflammation occurs due to metabolic disorders in the cells and tissues that make up each organ. Based on this theory, it was necessary to develop a apparatus to control acid-base balance and verify its effectiveness. This study was based on the pilot study which means for one subject. The redox reaction of human body was measured by pH/ORP meters after sampling in the urine and blood of the subject. EPA generates minus electron that works for reduction which means neutralizing hydrogen ions of oxidized metabolites. It is expected that lots of study can be perfomed about the relation between redox reaction of human body and disease status.

Objectives : The aim of this study is to set out case series study protocol to complete clinical pathway (CP) of hip and finger degenerative arthritis by applying CP, based on Korean medicine clinical practice guideline developed by clinical experts, to clinical field. Methods : The treatments included Manual acupuncture, acupoint injection, electroacupuncture, laser acupuncture, cupping, moxibustion, chuna, and physiotherapy. They were conducted in the 2nd week of admission and 4th week of out patient department (OPD) days. We carried out 10-point Likert scale questionnaires on the clinical usefulness and the satisfaction of patients and staff after applying CP. Appropriateness and improvement on patients were conducted using a 10-point Likert scale. An open-ended questionnaire was also conducted to ask if there was any requirement to be added. Results : In past research studies, there were no related studies about Korean medicine CP on hip and finger degenerative arthritis. Final version of CP is going to be completed based on the questionnaire. Conclusions : This evidence-based case series study protocol is expected to contribute development of hip and finger degenerative arthritis.
