Hyperhidrosis is the distressing condition of abnormal sweating which affects the palm, sole and axillary region. Transthoracic endoscopic sympathectomy is recommended as the treatment of choice for hyperhidrosis, especially when the upper limbs are affected. We experienced a case of accidental cauterization of right azygos vein in a healthy 23 year old male during endoscopic transthoracic sympathectomy. We changed the single lumen endotracheal tube to a double lumen tube which made it easier to perform the explo-thoracotomy and bleeder ligation under one lung ventilation. Crystalloid and colloid solutions, and packed RBC were loaded during explo-thoracotomy. Monitoring showed the signs indicating pulmonary edema. Pulmonary arterial catheterization revealed global heart failure. The patient was transfered to ICU for intensive management for heart failure. On the 4th postoperative day, pulmonary edema and heart failure were cured; and the patient was extubated. But in the evening of the same day ST-segment elevation and Q-wave were noted on ECG monitoring. On the 13th postoperative day coronary angiography was performed. This revealed left apex focal hypokinesia, patent coronary artery and accidental right coronary spasm, treated by vasodilator. On the 14 day, after surgery, he was discharged to return to work.

Idiopathic hyperhidrosis is a physically and emotionally distressing symptom, which lacks a precise definition. Although operative and nonoperative methods have been shown to be effective in the treatment of idiopathic hyperhidrosis, limitations, cautions and complications are inherent in their extended use. The purpose of this report is to describe the theraputetic effects of magnetic resonance for managing idiopathic hyperhidrosis. A 28 years old woman had been suffering from profuse sweating on both planter and palmar sides for 15 years. We successfully treated this symptom with the 6 magnetic resonance treatments without any complications. Now she lives well in a condition of normal sweating after the applications. It suggest that short daily periods of exposure to appropriate magnetic resonance can beneficially modulate the balance of autonomic nervous system that are responsible for sympathetic overflow, and that there is an effective window of induced electrical magnetism in which sympathetic function can be controlled in the absence of side effects.

Chronic pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain regardless of its etiology. Sympathetic nerve block is effective and safe for treatment of pelvic visceral pain. One of them, the inferior hypogastric plexus, is not easily assessable to blockade by local anesthetics and neurolytic agents. Inferior hypogastric plexus block is not commonly used in chronic pelvic pain patients due to pre-sacral location. Therefore, inferior hypogastric plexus is not readily blocked using paravertebral or transdiscal approaches. There is only one report of inferior hypogastric plexus block via transsacral approach. This approach has several disadvantages. In this case a favorable outcome was obtained by using coccygeal transverse approach of inferior hypogastric plexus. Thus, we report a patient who was successfully given inferior hypogastric plexus block via coccygeal transverse approach to treat chronic pelvic pain conditions involving the lower pelvic viscera.

This study aims at the new analysis of heart beat fluctuations by applying physiological Heart Rate Variability Model with representing the cardiac control system in sympathetic and parasympathetic-coupling oscillator constants, C_s and C_p. To find the effects of coupling constants on the beat-to-beat fluctuations, Integral Pulse Frequency Modulation (IPFM) model is adopted to generate the time series data of ECG R-peaks and represent them by poincaré scattergram plot in the time domain and HRV in the frequency domain, respectively. The actual poincaré plots and HRV spectrum are also analyzed by acquiring the experimental data from the subjects exposed to the emotional-stress invoking environment and the function of the coupling constants are verified in terms of antagonism in sympathetic and parasympathetic activity.

생물체는 스트레스에 대처하기 위한 항상성 유지 기작을 가지고 있으나, 만성적이고 반복적인 스트레스는 카테콜아민과 같은 스트레스 호르몬의 과도한 방출로 인해 인체에 해로운 영향을 미친다. 교감신경계와 암과의 관련성을 분석하는 연구는 스트레스가 암을 악화시킬 수 있다는 오랜 가설을 바탕으로 이루어졌다. 다수의 전임상연구와 역학 연구결과는 교감신경계의 주요 신호전달경로인 ${\beta}$-adrenergic signaling을 조절하는 것이 암의 진행을 억제할 수 있음을 보여주고 있다. 교감신경계의 활성화는 암세포의 oncogene과 DNA repair 유전자 조절, 생존과 사멸 조절, EMT 및 전이 조절, 면역계와 혈관신생 조절, 세포외기질과 간엽세포 조절, 지방세포 조절 등을 통해 암세포와 종양미세환경에 광범위하게 영향을 미칠 수 있다. 오늘날 암의 성장과 관련된 분자적 기전을 차단하는 표적항암치료가 각광받고 있으나, 보상경로의 활성화와 항암제 내성 출현 및 여러 부작용으로 말미암아 임상적 실패를 거듭하면서 암의 생병리를 다방면에서 조절하는 전략이 새로운 치료법으로 대두되고 있다. 본 총설에서는 이러한 암의 전신적 조절인자로서 교감신경계가 암의 형성과 발전에 미치는 영향을 요약하고, 향후 새로운 암 치료전략으로서 ${\beta}$-adrenergic signaling을 조절하는 약물의 임상적 활용가능성에 대해 논의하고자 한다.

In this paper, the power spectral analysis and fractral dimension analysis of heart rate variability(HRV) were performed to evaluate effects of orthostatic stress with head-up tilt on autonomic nervous system(ANS) for 24 young and healthy subjects(age: $24{\pm}5yr$.). The ECG and respiration signals were recorded at the tilt angle of $0^{\circ},\;15^{\circ},\;30^{\circ},\;45^{\circ},\;70^{\circ}$ and $90^{\circ}$ successively for 5 minutes per each stage under the condition of frequency controlled respiration (0.25Hz). Heart rate(HR) gradually increased as the angle increased. Similarly, according to the increment of angle, normalized low frequency(LF) component(0.05-0.15Hz) gradually increased, whereas normalized high frequency(HF) component (0.20-0.30Hz) was reduced. From these results it is speculated that orthostatic stress, head-up tilt, results in the prevalence of sympathetic tone in autonomic balance with the increment of sympathetic tone and the decrement of parasympathetic tone, which seems to mean that autonomic nervous system plays a major role in compensating for disturbances of cardiovascular system due to it.

Objective : Hyperhidrosis is the secretion of sweat in amounts greater than physiologically needed for thermoregulation. Ryodoraku is a physiological function test using electric current, and is closely related to skin sympathetic tone. The aim of this study was to investigate the characteristics of Ryodoraku and association of Ryodoraku with hyperhidrosis. Methods : For this study, we conducted Ryodoraku on 56 people, comprising 33 with palmar-plantar hyperhidrosis and 23 with head-face hyperhidrosis, who visited the 5th Internal Department of the Oriental Medicine Hospital of Kyung Hee University during the period from March 1, 2008 to May 31, 2009. Ryodoraku scores were evaluated and compared by 7 indices(upper, lower, left, right, yin, yang, total score). Results : Ryodoraku scores were significantly higher in hyperhidrosis patients than the normal group. Ryodoraku scores of palmar-plantar hyperhidrosis patients were significantly higher than of head-face hyperhidrosis patients and the normal group. The difference of Ryodoraku indices among palmar-plantar hyperhidrosis patients were insignificant. In head-face hyperhidrosis patients, the upper index was significant higher than the lower index. Conclusions : In hyperhidrosis patients, all indices were significant higher than lower. The upper/lower ratio was significant higher in head-face hyperhidrosis patients.

Purpose: To determine effects of family conflict mitigation documentary programs on conflicts, autonomic nerve activation (ANA), and happiness of elderly in long-term care hospitals. Methods: This study used a non-equivalent control group with a pretest-posttest design. It was conducted on 39 elderly patients (19 in the experimental group and 20 in the control group) in long-term care hospitals. The experimental group (n=19) received family conflict mitigation documentary programs. The family conflict mitigation documentary programs consisted of four sessions (40-50 minutes per session). These programs were implemented in small groups, with each group having five elderly. Data were analyzed by sing the conflict checklist, the Oxford Happiness Questionnaire, Chi-square test with Fisher's exact test, independent t-test, paired t-test, and repeated measure ANOVA using the SPSS/WIN 21.0 program. Results: The participants in the experimental group showed significantly decreased scores of conflict (t=-2.31, p=.028) and the value of sympathetic nervous system activity (t=8.36, p=.007) compared with those of the control group. The participants in the experimental group showed significantly increased the value of parasympathetic nervous system activity (t=-2.91, p=.008) and scores of happiness (t=5.46, p<.001). Conclusion: The family conflict mitigation documentary programs on conflicts, ANA, and happiness of the elderly in long-term care hospitals are effective intervention programs for mitigating conflicts between elderlies and their families and for improving happiness of the elderly in long-term care hospitals.
