Following thesis is about comprehensive treatment of insomnia through stability of the autonomic nervous system. It is widely accepted that most of the relevant symptoms of insomnia can be blamed on successive instability of the autonomic nervous system. In order to treat insomnia effectively, it is essential to maintain stability in the autonomic nervous system. When one is at stable stage of the autonomic nervous system, one maintains steady hormonal discharge. In Oriental Medicine, it is the stage when one has a sound qi-blood circulation. To treat insomnia effectively, one has to obtain both physical and mental relaxation through various ways.

Objectives : Fructus mume(F. mume) has been used as a medicine for thousands of years in East Asia and reported to have effect on cognitive deficits induced by chronic cerebral hypoperfusion. We investigated F. mume's effects on psychiatric and central nervous system in medical classics. Methods : 25 materia medica books and Donguibogam were searched to find psychiatric and central nervous system effects of F. mume. Two Korean Medicine doctors reviewed the effects from the clinical point of view. Results : 安心(relieve psychiatric discomfort), 令人得睡 治不眠(Treat insominia), 去煩悶(relieve chest discomfort) were psychiatric effects and 偏枯不仁(hypoesthesia accompanied with hemiplegia) was central nervous system effect of F. mume. Conclusions : Further studies will be needed to demonstrate F. mume's effects found in medical classics.

By far, studies on the effect of oral administration of peppermint essential oil on blood pressure are not consistent, increasing or decreasing. And the effect of inhalation of peppermint essential oil on blood pressure was not reported. This study was designed to clarify the effect of peppermint essential oil inhalation on the blood pressure and autonomic nervous system. Blood pressure and heart rate variability (HRV) as an indicator of autonomic nervous system activity were measured. The systolic and diastolic blood pressure was not changed significantly by inhalation of peppermint essential oil. Standard deviation of normal to normal (SDNN), a parameter of total activity of autonomic nervous system also was not changed significantly. High frequency (HF) power level, an indicator of parasympathetic nervous system activity was not changed by peppermint. These results indicate that action mechanism of peppermint essential oil on blood pressure is different by the method of administration, oral or inhalation.

In this paper, we designed a multimodal bio-signal measurement system to observe changes in the brain nervous system and vascular system during sleep. Changes in the nervous system and the cerebral blood flow system in the brain during sleep induce a unique correlation between the changes in the nervous system and the blood flow system. Therefore, it is necessary to simultaneously observe changes in the brain nervous system and changes in the blood flow system to observe the sleep state. To measure the change of the nervous system, EEG, EOG and EMG signal used for the sleep stage analysis were designed. We designed a system for measuring cerebral blood flow changes using functional near-infrared spectroscopy. Among the various imaging methods to measure blood flow and metabolism, it is easy to measure simultaneously with EEG signal and it can be easily designed for miniaturization of equipment. The sleep stage was analyzed by the measured data, and the change of the cerebral blood flow was confirmed by the change of the sleep stage.

Objectives : This study aims to overview the therapeutic mechanism of back-shu points in terms of sympathetic visceral motor nervous system. Methods : Studies about autonomic nervous system, and studies and ancient texts about back-shu points were reviewed. We interpreted possible mechanism of back-shu points considering similarities of anatomical and physiological characteristics of back-shu points and visceral motor nervous system. Results : Afferent signals for organ lesions that can develop the symptoms of autonomic neurological symptoms, pain, hyperalgesia through the skin segment. Through a physical examination of the myotome and dermatome, it is possible to diagnose segmental disorders. Treatment stimulation of the thick fibers of the disorder segment skin can reduce abnormal autonomic influence over the sympathetic reflex mechanism. In addition, if spinal muscles are relaxed, the pressure on the nerve roots could be reduced and consequently the hyperactivity of the sympathetic visceral motor signal would be suppressed. Conclusions : The back-shu points treatments work through the mechanism of the sympathetic nervous reflex. Moreover, segmental acupuncture can reduce tension of the spinal muscles, thereby improving pathological conditions of the sympathetic nervous system.

본 연구의 목적은 완전몰입 가상현실이 자율신경계에 미치는 영향을 알아보는데 있다. 본 연구의 대상자는 가상현실 장비를 접하지 않은 17명의 20대 남성으로 하였다. 대상자에게 완전몰입 가상현실 콘텐츠를 제공받았고, 적용 전과 후에 5분 동안의 심전도 신호를 측정하였다. 획득한 심전도 신호는 교감신경계의 활성을 반영하는 LF, 부교감신경계의 활성을 반영하는 HF, 자율신경계의 전반적인 활성을 반영하는 TP, 그리고 자율신경계의 활성 균형을 반영하는 LF/HF로 분석하여 자율신경계를 평가하였다. 그 결과, 완전몰입 가상현실을 적용한 후 대상자의 HF와 TP는 적용 전에 비해 유의하게 감소하였고, LF/HF는 유의하게 증가하였다. 본 연구의 결과에 따르면 완전몰입 가상현실은 자율신경계에 스트레스를 제공하지만, 그 변화는 건강한 성인의 정상범위 내에 있다는 것을 확인할 수 있었다. 따라서 완전몰입 가상현실은 건강한 성인에게 안전하게 적용될 수 있다.

최근 3D TV 보급과 확산에 따른 시각 피로문제가 대두되면서 시각 기능과 인지적 관점에서의 연구가 활발하다. 그러나 3D 시각피로가 자율신경계 기능에 미치는 영향에 대한 연구는 미비하다. 따라서 본 연구에서는 3D TV 시청으로 유발되는 3D 시각피로가 자율신경계 기능에 미치는 영향과 이 영향이 교감 및 부교감 신경계와 심혈관계 반응에 미치는 영향을 확인하고자 한다. 피험자는 20 대 남녀 대학생 15 명(남 6 명, 여 9 명, 평균나이 22.53 세 ${\pm}$ 2.55 세)을 대상으로 하였다. 피험자는 편안한 의자에 앉아 3D TV를 1시간 시청하였다. 3D TV 시청 전과 후의 1분간 맥파(PPG, Photo-PlethysmoGram)를 측정하였고 주관설문을 실시하였다. 측정된 신호에서 SDNN (standard deviation of RR intervals), RMS-SD(root mean square successive difference), HF/LF ratio, Ln(LF), Ln(HF)를 추출하여 교감 및 부교감 신경계, 그리고 심혈관계 반응을 확인 하였다. 연구 결과 HF/LF ratio, Ln(LF), Ln(HF)는 시청 후에 유의하게 감소하였고, SDNN, RMS-SD는 통계적 유의차를 확인할 수 없었다. 이 결과는 3D 시각피로가 자율신경계 기능에 영향을 미치고 이로 인해 교감신경계가 항진되는 반응이 나타나며, 심박 변화율이 감소하는 결과를 초래할 가능성을 확인 하였다.

Acrylamide의 신경독성에 대해 조사하기 위하여 초기운동실조증이 유도된 생쥐의 신경계에 대한 Acrylamide의 영향을 관찰한 결과, 중추 및 말초신경조직에 있어서의 손상이 보여 척수의 전반적 공포현상, 신경원 및 신경교의 세포손상 그리고 말초신경섬유의 퇴행현상들이 보였다. 또한 이들에 대한 미세구조적 관찰에 의하여 신경원에서의 비정상적 미토콘드리아 및 척수전근 섬유에서의 수초의 균혈화 현상등이 야기됨을 알았으며 좌골신경에서의 수초의 부분적 붕괴 및 축삭형질내의 퇴행현상들도 보였다. 위와 같은 실험결과는 Acrylamide로 인한 중독의 영향이 말초신경장애의 증상으로 나타나나 최초의 신경독성효과는 중추 및 말초신경계에 대해 거의 유사한 시기에 작용함을 시사한다.

PURPOSE : The effect of the vestibular caloric stimulation with ice water on the autonomic nervous system was investigated using pulse oximetry. METHOD : Thirty-four healthy men and women were subject to a 2-minute vestibular caloric stimulation with ice water, and autonomic nervous activities (low frequency, high frequency, and total power) were measured before and after the vestibular caloric stimulation. Data were analyzed separately for men and women. RESULT : Low frequency, high frequency, and total power in the men and low frequency in the women were statistically significantly higher after vestibular caloric stimulation. High frequency and total power in the women were higher but not significantly different after vestibular caloric stimulation. CONCLUSION : Vestibular caloric stimulation with ice water increases autonomic nervous activities, with the variation being within the normal range. The test can be considered safe for use.

There are many hypothesis about mechanism of acupuncture, and the relationship between acupuncture stimulation and autonomic nervous system(ANS) is one of the powerful hypothesis. The purpose of this study is to investigate the relationship between acupuncture stimulation and ANS. We searched the literature and reports related with acupuncture stimulation(meridian system, meridian points) and autonomic nervous system. And we concluded acupuncture stimulation can control autonomic nervous system. We reviewed studies that contributed to an understanding of the autonomic mechanisms of acupuncture with the hope that this review will be of benefit to the acupuncture treatment.
