Objectives : Accumulation point is a useful acupoint for acute pain diseases. Among the eight extra meridians, only four (Yin Heel, Yang Heel, Yin Link, Yang Link vessel) have accumulation point and the others (Governor, Conception, Thoroughfare, Belt Vessel) do not. However, there is no explanation why these four meridians do not have it. So, the authors researched the literature to look for the reasons. Methods : We investigated 10 books and 1 paper about the 'accumulation point of extra meridians' using several search engines and researched reason why the other 4 meridian do not have it. Results : All of the 16 accumulation points are located on the 4 limbs. The four limbs have more Yang energy than the trunk. The governor, conception, thoroughfare, and belt vessels do not flow in the limbs. It seems that there is no acupoint located on deep gap enough to be the accumulation point among the four vessels. When it comes to the functions of these vessels, they are little related with the acute pain that is the main target of the accumulation point. Conclusions : From the results of this study, it seems to be reasonable that the four vessels do not have accumulation point.

Objectives : In the acupuncture treatment of Korean Medicine, the Tonifying or Purging depending on how many times the needle is rotated has been used widely. However, there is little evidence about the optimal number of rotation. This study, therefore, was aimed to investigate the optimal number of rotation. Methods : Heart rate variation was measured before and after exercise in 20 healthy adults. Acupuncture was performed at PC6 immediately after exercise according to the protocol of each group without remaining. Pre-exercise and post-exercise measurements were compared and the rotation number that produced statistically significant difference was investigated. Results : Significant differences were found in the heart rate variation and R-R interval Average, between non-rotation group (control) and both of 15 times rotation group of tonifying and 6 times rotation group of purging. Conclusions : Significantly effective number of rotation in the effect of PC6 on the HR and RRAv was 15 times in the tonifying and 6 in the purging respectively.

Objectives : To observe the changes in the expression of nNOS, iNOS, eNOS and NO by the needle insertion on river points, one of the five transport points of three yang meridians of the foot. Methods : Based on rats, needle was inserted on both left and right sides of ST41, BL60 and GB38 and retained for five minutes. After the retention, blood was drawn via cardiac puncture and tissues from each point around meridian vessels were extracted to observe the changes in the expression of nNOS, iNOS, eNOS and NO. Results : In terms of the effect on expression of nNOS within tissues, ST41 showed significant decrease based on the results of immunohistochemistry. In terms of the effect on expression of iNOS within tissues, none of the experimental groups showed any significant change compared to the Normal group. Regarding expression of eNOS within tissues, GB38 showed significant increase based on the results of immunohistochemistry. In terms of the effect on NO creation in tissues, none of the experimental groups showed any significant change compared to the Normal group. Conclusions : The effect of needle insertion on the river points of three yang meridians of the foot on the function of nNOS, iNOS, eNOS and NO could be observed, and based on this study, it is considered that the effect of needle stimulation on the changes of nervous system could be found out through additional research.

Objectives : The purpose of this study is to analyze an effect of medical Qigong therapy using Dong Chu Chim (DCC) which was invented by "Dongchu Han Medicine Institute", by measuring HRV. We compared effects of DCC with non-treatment, filiform acupuncture and filiform acupuncture with natural abdominal breathing. Methods : 1. The authors stimulated Nogung (PC8) of 26 normal adults by using DCC or filiform acupuncture in turn. 2. The natural abdominal breathing has been carried comfortably with consciousness in the lower abdomen. 3. HRV was measured for 5 minutes, three times (pre-treatment, during-treatment and post-treatment). Results and Conclusions : From this study, it seems that the stimulus of DCC, filiform acupuncture, filiform acupuncture with natural abdominal breathing can all affect the autonomic nervous system and control the balance of that. But there were not significant differences between these stimulus groups and the non-treatment group. Therefore, we suggest additional studies about the effect of DCC in the future.

Objectives : The purpose of this study is to evaluate the efficacy of acupuncture treatment on the inflammatory lesions and body image disturbances in patients with vulgaris acnes. Methods : Fifteen inflammatory acne patients were enrolled and treated with facial acupuncture during 4 treatment sessions. We evaluated the number of papules and nodules using the Korean Acne Grading System (KAGS). We also evaluated patients' general subjective satisfaction and objective changes of inflammatory acnes symptoms using DermaVision-pro. Moreover, we observed the skin quality-of-life scale with skindex-29 and body image disturbance questionnaire (BIDQ) as secondary outcome. Adverse events were recorded as well at every visit. Results : After 4 treatment sessions, there were significant reductions in the number of papules and nodules of the patients. We found that subjective satisfactions of patients were enhanced as well as the objective inflammatory symptoms. We also found significant improvements in the quality of life and BIDQ. No serious treatment-related adverse events were reported. Conclusions : This study demonstrated that standardized facial acupuncture were effective and safe in the treatment of facial inflammatory acnes.

Objectives : The fact that Primo vessel as a new circulatory system exists in the lymphatic vessels of the rabbits which were treated with sound wave vibration therapy is confirmed with the anatomy of rabbit. Isolated Primo vessel is investigated, particularly focused on morphological features. Methods : Before the anatomy, a rabbit in a cage box was laid on the sound wave vibrating apparatus and then is applied by various frequencies and intensities for 30 min with music that a rabbit likes. Results : Isolation and observation of Primo vessel was easier when the lymphatic circular system was applied at a certain frequency and intensity of 7 Hz and 50. The probability of observation for Primo vessel enhanced to 90%. Conclusions : The sound wave therapy by a vibration apparatus is considered necessary as major process to facilitate the reproducible isolation and observation of Primo vessel.

Objectives : This study was performed to investigate the relationship between Sasang Constitution and length of chest and abdomen region. Methods : Forty eight participants were enrolled. Weight, height, and lengths from CV22 to CV16, from CV16 to CV8, and from CV8 to CV2 were measured. Ratios of last three lengths to total CV22 to CV2 were calculated respectively. On the other hand, Sasang Constitution was analyzed with QSCCII(Questionnaire of Sasang Constitutional Classification II). The analysis of relationship between the measurements and Sasang Constitution was carried out with SPSS to compare the mean values according to Sasang Constitution. Results : All the mean values were not significantly different depending on the Sasang Constitution, except the ratio of the length from CV16 to CV8 to the length from CV22 to CV2, only in female participants. The ratio was higher in the female Soeumin participants than any other constitutional groups. Conclusions : This result showed that Soeumin could be assumed that they might have weak digestion abilities.

목적 : 본 연구는 노년층의 여성에게 신맥(BL62), 조해(KI6)혈에 대한 저주파자극이 뇌파에 어떠한 영향을 미치는지 알아보고 뇌 기능을 개선하는데 비화학적이고 비침습적인 자극 방법의 후보로써 가능성을 탐구해보고자 실시된 탐색적 연구이다. 방법 : 31명의 건강한 여성 피험자(평균연령, 54.5세)를 대상으로 이중맹검 무작위배정 임상연구가 12세션동안 실시되었다. 시험군에서는 감지할 수 없는 최대의 저주파자극이 실시되었으며(평균전류량, $0.04{\mu}A$), 대조군에서는 거짓자극이 실시되었다. 결과분석을 위해 12세션을 전후로 배경뇌파가 측정되었다. 결과 : 12세션의 자극이 실시된 후 대조군에 비해 실험군의 알파파 상대값은 11채널에서 유의한 증가를 보였으며(p<0.05), 감마파의 상대값은 7채널에서, 세타파의 상대값은 10채널에서 유의한 감소를 보였다. 결론 : 발목관절에 있는 신맥(BL62), 조해(KI6)혈에 대한 저주파 자극은 노년의 여성의 뇌에 베타, 세타, 감마파의 감소를 일으키는 반면 알파파를 선택적으로 증가시켜 뇌를 안정시키는 효과가 있는 것으로 보인다. 이러한 결과는 저주파자극이 향후 스트레스와 관련된 인지 문제를 치료하는 비침습적이고 비화학적인 도구로써의 가능성을 제공할 수 있을 것으로 보이며, 그 기전에 대한 추가적 연구가 필요할 것으로 보인다.
