한의학에서 진단과 치료의 기본 대상인 경혈?경락의 혈위 식별을 위한 방법으로 기존의 방식은 직류를 인체 피부에 자극하여 양도점을 식별하고 있다. 그러나 직류는 피부의 저항과 용량성으로 인한 시간에 따른 전류 감소현상을 나타내며, 이러한 시간적 감소현상은 경락진단의 변수로는 유의성을 가지나 식별율 및 부합율, 인체영향력, 재현성 등에서 식별데이터의 신뢰성이 충분하지 못한 단점이 있었다. 이를 개선하기 위하여 1.28V의 4kHz, 듀티비 40%의 구형파인 SPAC(Single Power Alternative Current) 자극방식의 최적 파라메터를 추출하였다. 또한 피부 상태에 관계없이 식별이 어려운 부위에서도 식별이 용이하도록 피부 전류량의 절대값과 상대값을 동시에 표시하고, 측정 전류량을 그래프로 연속 표시하여 식별에 유리하도록 하였다. 추출된 최적파라메터와 알고리즘을 적용한 시스템을 구현하여 경혈자극 방식에 따른 식별율, 재현성, 인체영향력 및 고전 경혈점과의 부합율을 비교하여 성능이 우수함을 확인하였다.

Objectives : The aim of this study was to understand electro-physiological peculiarity in meridian and acupoints, and understand acupuncture therapy mechanism as an electro-physiological viewpoints. Methods : I reviewed the articles on the electro-physiological peculiarity of the meridian and acupoints Results and Conclusions : It has been reported that meridian and acupoints have high-electrical conductivity and row-electrical resistance. On this scientific basis, to understand the mechanism of acupuncture therapy, I made some hypotheses. At first, there is electro-property in meridian and acupoint. The second, energy flowing in meridian is related with electro-property. The third, there is electronic interaction between practitioner of acupuncture therapy and patient receiving acupuncture therapy. The forth, acupuncture effects which may be expressed by the electro-charge capacity is transfered between practitioner and patient via acupuncture. Electro-charge induced via acupuncture in practitioner may be an important factor that initiate the electro-charge changes in meridian and acupoint of patient.

목 적 : 전침 자극은 최근에 임상연구와 더불어 기초연구에서 자주 사용하는 방법으로 경락이론에 의거하여 신체에 분포되어 있는 경락상의 각종경혈부위에 인위적인 전기 자극을 통하여 질병을 치료, 예방 혹은 완화하는 방법이다. 이에 본 연구에서는 정상적인 쥐의 상태에서 일정한 전침 자극을 주었을 때, 심박변이도의 변화를 측정 하였다. 방 법 : 쥐의 정상적인 마취상태에서 태충혈에 4 Hz와 80 Hz의 5 V 크기로 10 mA 강도의 사각파 파형으로 자극을 주었으며 대조조로 비경혈 부위에 4 Hz의 동일한 파형으로 자극을 주어 심박 변이도의 변화정도를 측정하였다. 결 과 : 본 실험에서 RR Interval의 경우 태충혈 4 Hz 보다 80 Hz일때 RR Interval의 파형이 더 크게 나타났으며, PSD의 분석에서도 자극 전후를 비교하였을 때 $1{\sim}3$ Hz 사이에 높은 피크가 보였으며 4 Hz의 비경혈 부위에서는 큰 변화를 보이지 않았다. 결 론 : 이번 실험연구를 통하여 정상적인 쥐의 상태에서 일정한 전침 자극을 주었을 때, 심박 변이도 변화를 도출할 수 있었으며, 이번 실험을 통해 비수술적인 방법으로 치료효과와 심박 변이도를 측정할 수 있었고, 이를 통해 전침자극의 기전 연구에 있어 과학적 근거를 제시할 수 있다고 사료된다.

Objectives : Acupuncture points and meridians have been usually depicted as a two dimensional drawing and verbal description. Recently, imaging and three-dimensional image processing technologies have been introduced into medical fields such as anatomy and virtual operation, for the purpose of enhanced efficiency in research and education. This study attempted an image modelling of the meridian and acupoint in the upper limb region. Methods : A vector image model of an arm was produced and medical information on the meridian and acupoint of the arm region was incorporated. Results : A 3D modelling of the acupuncture meridian and acupoint in the upper limb region was produced along with a user console to control the presentation of related information and to facilitate visualization of the 3D model images. Conclusions : A 3D modelling of the acupuncture meridian and acupoint will be an efficient platform for an education and research.

Objectives : This study investigated the current utilization status of thermotherapy devices in Korean medicine (KM) institutions and identified areas for improvement and further development, as perceived by KM doctors (KMDs). Methods : An online survey was conducted, targeting KMDs primarily engaged in clinical patient care. The questionnaire included items about respondents' clinical practices, the extent of thermotherapy device usage, their opinions on these devices, and perceived improvement needs. The collected data underwent quantitative analysis. Results : From the 1,025 respondents, data from 862 respondents who provided complete responses were analyzed. On average, respondents utilized thermotherapy treatments for 80% of their patients. Infrared (IR) phototherapy unit, electrical moxibustion apparatus, and heater-based thermotherapy devices were predominantly owned by respondents, with IR being the most frequently used. The average satisfaction score for current thermotherapy devices was 79. A significant concern raised was the necessity for improved health insurance coverage and efficacy evaluation. Conclusions : This research has confirmed that the extensive use of thermotherapy devices by KMDs in treating primarily musculoskeletal and gastrointestinal ailments - common conditions among patients in KM institutions. The main areas identified for improvement encompass safety, cost-effectiveness, and device efficacy. Future enhancements in thermotherapy devices should address these crucial aspects.

Objectives : In this study, we investigated the neuroprotective effects of ethanol extract of Lonicera japonica flower buds (EELJ) on glutamate-induced neurotoxicity in mouse hippocampus-derived neuronal HT22 cells. Methods : After analyzing the cytoprotective effect of EELJ on glutamate in HT22 cells, the inhibitory effect of apoptosis was studied using flow cytometry. In order to analyze the antioxidant efficacy of EELJ, the levels of reactive oxygen species (ROS) and glutathione (GSH) were investigated, and the effects on the activities of superoxide dismutase (SOD) and catalase (CAT) were also analyzed. Furthermore, the effect of EELJ on the expression of apoptosis regulators such as Bax and Bcl-2 in glutamate-treated HT22 cells was investigated. Results : According the current results, pretreatment with EELJ significantly reduced glutamate-induced loss of cell viability and release of lactate dehydrogenase. EELJ also markedly attenuated glutamate-induced generation of intracellular ROS, which was associated with increased levels of GSH, and activity of SOD and CAT in glutamate-stimulated HT22 cells. In addition, EELJ was strikingly inhibited glutamate-induced apoptosis in HT22 cells. Furthermore, the expression of pro-apoptotic Bax was increased and the expression of anti-apoptotic Bcl-2 was decreased in glutamate-treated HT22 cells, while in the presence of EELJ, their expressions were maintained at the control levels. Conclusions : These findings indicate that EELJ protects glutamate-induced cytotoxicity in HT22 hippocampal neurons through antioxidant activity. Therefore, although identification of biologically active substances of EELJ and re-evaluation through animal experiments is necessary, this natural substance is a promising candidate for further research in preventing and treating oxidative stress-mediated neurodegenerative diseases.

Objectives : The purpose of this study was to investigate the needling depth of five-phase acupoints and discuss the association with the depth of meridian qi. Methods : DongUiBoGam was used to determine the depth of five-phase acupoints. The depth of needling at 60 five-phase acupoints was compared between well, spring, stream, river, and sea acupoints. Results : The proximal part of the extremities had deeper needling depth than the distal part of the extremities. The targeted deqi sensation can be related to the needling depth. Conclusions : The depth of the meridian qi is related to the distinct patterns of needling depth of five-phase acupoints.

Objectives : Moxibustion-related standards have been established by organizations such as the International Organization for Standardization (ISO) and the Korean Standards Association (KSA), among others. Methods : We summarized moxibustion-related standards that have been published by ISO and KSA. Results : Technical Committees 249 (ISO/TC 249), which was established in 2009, has been established moxibustion devices standards in working group (WG) 4. International standards have been established for moxibustion devices, smokeless moxibustion devices, moxa floss quality, and electric heating moxibustion equipment. Work on international standards for infrared moxibustion-like instruments and moxibustion device terminology is currently in progress. Conclusions : Korea has taken a central role establishing international standards for a wide range of moxibustion devices, supported by fundamental research data in this field. To continue its influence in establishing these international standards, further studies providing the basis for moxibustion device standardization are required.
