목적 : 심박수 변이도(Heart Rate Variability. HRV)를 통해 사암침법 치료법 중 심신 질환에 많이 적용되는 심정격 자침법과 자율신경계와의 관계를 살펴보고자 하였다. 방법 : 2006년 5월 1일부터 2006년 6월 31일까지 2개월간 특별한 과거력이 없는 건강인을 대상으로 실험군 37명을 사암침법 심정격을 자침하고 시술 전후에 HRV를 측정하여 별무처치 상태로 안정을 취한 후 측정한 대조군 21명과 비교하였다. 결과로 얻은 MHRT, SDNN, RMSSD, TP, LF, HF, LF/HF ratio 등의 수치 변화를 비교해 기록 시간 동안의 평균 심박수, 외부 스트레스에 대한 심박동의 변화상태, 심장에 관여하는 자율신경 중 부교감신경의 활동, 교감신경과 부교감신경의 균형 상태 등을 분석하였다. 결과 1. MHRT는 실험군에서 유의성이 있는 것으로 나타났다. 2. SDNN는 실험군 대조군 모두 통계적인 유의성이 없었다. 3. RMSSD은 실험군 대조군 모두 통계적인 유의성이 없었다. 4. TP는 실험군 대조군 모두 통계적인 유의성이 없었다. 5. LF, HF은 실험군 대조군 모두 통계적인 유의성이 없었다. 6. LF/HF ratio는 실험군에서 유의성이 있는 것으로 나타났다. 결론 : 부교감신경과 교감신경의 비교 지표로 다용되는 LF/HF ratio가 유의한 차이를 보여 심정격 자침이 자율신경계의 항진을 완화시키는 것으로 사료된다. 향후 환자의 병인과 상태에 따라 실증과 허증으로 구분하여 시술하는 등의 추가적인 연구가 필요할 것으로 사료된다.

1. Objectives To evaluate effects of bee venom acupuncture on cardiovascular system and differences according to each constitution. 2. Methods Heart rate variability, pulse wave and the velocity of cerebral blood flow were measured before bee venom acupuncture(BVA), right after and after 30 minuets, had been applied to 20 subjects. 3. Results 1. BVA did not have effects on measurement variables of heart rate variability. 2. BVA had effects on pulse wave, showing total time, radial augmentation index up and height of percussion wave, time to percussion wave, sum of pulse pressure down. 3. BVA did not have effects on the cerebral blood flow velocity when considering not Sasang Constitution. 4. Considering Sasang Constitution, BVA demonstrates different responses in time to preincisura wave, mean blood flow velocity, peak systolic velocity and end diastolic velocity. 4.Conclusion From those results, the following conclusions are obtained. Cause BVA alters pulse wave and makes differences in the cerebral blood flow velocity according to Sasang Constitution. Various methods of BVA treatment are needed considering Sasang Constitution.

Purpose: This study was performed to analyse autonomic nerve function of some examinees with dysmenorrhea by comparing the characteristics of dysmenorrhea patients' Heart Rate Variability(HRV) in examinees group with non-examinees group. Methods: We studied 110 patients visiting OO Korean hospital to take medical treatment for dysmenorrhea from September, 2006 to August, 2010. The subjects were categorized in two groups, 36 examinees and 57 non-examinees controls. We investigated the difference of HRV between two groups by student's T-test using SPSS for Windows(version 12.0). Results: 1. SDNN in examinees group is statistical significantly lower than non-examinees group. RMS-SD in examinees group is lower than non-examinees group non-statistical significantly. Mean PR in examinees group is higher than non-examinees group non-statistical significantly. 2. VLF, ln TP, ln VLF and ln HF are statistically significantly lower than non-examinees group. TP, HF and ln LF are lower than non-examinees group non-statistical significantly. LF is higher than non-examinees group non-statistical significantly. Conclusions: The results suggest that stress is related to especially examinees in dysmenorrhea patients by effecting autonomic nerve function. HRV can be useful to diagnose examinees' dysmenorrhea. The further studies would be needed to study about relation between stress, dysmenorrhea and HRV for settling this.

The purpose of this study is to investigate the relationships between the biological base of coping strategy and the different constitutions. First of all, subjects were divided in to 3 groups dy Questionnaire for the Sasang Constitution Classification II and Yin-Yang Property Analysis. Then each group was assigned into two experimental coping conditions, active and passive condition, in turn. The SDNN(The Standard Deviation of the NN Intervals) of HRV(Heart rate variability) index was estimated from two conditions after giving a aversive pain stimulus. The results of the study were as follows 1. The interaction between constitution and coping condition is significant(p<0.05). 2. The SDNNs of Shaoyangren are higher than those of Taiyinren under passive condition but it was opposite under active condition(p<0.05). 3. The main effect of constitution is also significant but that of coping condition is not significant. 4. Thee Shaoyangren is higher than Shaoyinren in multiple comparisons(p<0.05). 5. The interaction between Yin-Yang constitution and coping condition is significant and the main effect of only constitution is significant(p<0.05). According to these results, different constitution can respond differently to coping condition and It is highly related to biological mechanism associated with two basic coping strategies.

Purpose: The purpose of this study is to analysis on the Heart Rate Variability(HRV) of some dysmenorrhoea patients. Methods : We studied 30 patients visiting Kyung Hee University East-West Neo Medical Center from 7th Febrary 2007 to 22th Febrary 2007. Women with organic disease were excluded from this study. The severity of dysmenorrhoea were measured by Multidimensional Verbal Rating scale(MVRS), Verbal Rating scale (VRS) and Visual Analog Scale(VAS). And HRV was recorded. Results : According to comparison of Means of HRV values among the groups of None, Mild and Moderate, the points of almost all values were kept by order of Moderate group-Mild group-None group. Among these, the statistically significant things are PR, SDNN, Ln (TP), Ln (VLF), Ln (LF). According to correlation analysis between dysmenorrhoea and HRV, specially, there were many correlations in VRS2. Among these, the statistically significant things are LF norm, HF norm, LF/HF ratio(p<0.05L). Conclusion : The results suggest that HRV is related to dysmenorrhoea. We may analyze that dysmenorrhoea is related to, specially, increased activities of sympathetic nerve. We need more study for settling this.

Objectives The aim of this study is to investigate the related factors of nonalcoholic fatty liver disease (NAFLD). Methods The subjects were 187 persons diagnosed as fatty liver by abdominal ultrasonography. They were divided into three groups according to the severity of fatty liver: control, mild, moderate or severe. The three groups' general characteristics, laboratory results, liver function indexes, metabolic syndrome indexes, tumor markers, heart rate variability values and Sasang constitution distribution were compared and analyzed. Results Male ratio, height, weight, body mass index, red blood cell count, hemoglobin level and creatinine level were higher in NAFLD groups than in control group. The levels of sodium and amylase were higher in control than in NAFLD. In liver function, the levels of aspartate transaminase, alanine transaminase and gamma-glutamyl transpepsidase of NAFLD were higher. In metabolic syndrome index, systolic blood pressure, diastolic blood pressure, waist circumference, total cholesterol, triglyceride and low density lipoprotein cholesterol levels were higher in NAFLD, while high density lipoprotein cholesterol level was higher in control. The alpha-feto protein level was higher in NAFLD, and the heart rate variability was not different between NAFLD and control groups. In Sasang constitution, Taeeumin ratio of NAFLD was higher than of control. Conclusions The results suggest that nonalcoholic fatty liver is clinically related to liver dysfunction, metabolic syndrome, tumor markers, and Sasang constitution. Further studies are needed to control nonalcoholic fatty liver disease and prevent severe disease such as cirrhosis and cancer caused by fatty liver.

Objective: Disorder of the autonomic nervous system is considered to be the cause of primary dysmenorrhea. The spine has a close relationship with the autonomic nervous system, and the sacrum is mechanically and neurologically connected to the uterus through ligaments. Therefore, this study was conducted to check the effect on the autonomic nervous system through measurement of heart rate variability by applying manual therapy to the sacroiliac joints of subjects with primary dysmenorrhea and to suggest an effective treatment method for dysmenorrhea. Design: Randomized controlled trial. Methods: Thirty females with dysmenorrhea were assigned to either the manual therapy group and sham treatment group according to the random treatment method. The manual therapy was applied to the sacroiliac joints, and the sham treatment was only treated with the hands placed in the same position of the intervention. Heart rate variability and the Visual Analogue Scale (VAS) were measured on the day when menstruation began ±2. Interventions were performed between the groups, followed by a 5-minute break and then re-measurements were made. Results: There were significant differences in autonomic balance and VAS scores in the manual therapy group before and after the intervention between groups (p<0.05). In the sham treatment group, there were significant differences in low frequency, autonomic balance, and VAS scores (p<0.05). There were significant differences in autonomic balance between groups (p<0.05). Conclusions: In females with primary dysmenorrhea, manual therapy applied to the sacroiliac joint was found to be effective for a short time on autonomic activity.

Objectives: The purpose of this study was to analyze the correlation between the level of xerostomia and Yin deficiency as well as heart rate variability in patients with halitosis. Methods: A survey was conducted on 30 patients who visited the Department of Internal Medicine at Dongsin University Oriental Hospital from March 2021 to February 2022. A questionnaire regarding halitosis and xerostomia was administered using the Visual Analogue Scale (VAS) scores, and Yin deficiency was assessed using 10 specific items. Oral moisture was measured using the Oral Moisture Checking Device (Mucus) under unstimulated conditions, while heart rate variability was measured with the SA-6000 equipment. Results: A significant positive correlation was found between VAS scores for halitosis and xerostomia and Yin deficiency. However, there was no correlation between xerostomia and the Mucus scores. The low Mucus score group showed a significant negative correlation with LF values compared to the normal Mucus score group. Conclusion: Patients with halitosis who experience xerostomia are likely to be in a state of Yin deficiency.
