Objectives: Acupuncture has been shown to relieve pain and modulate biological function by stimulating the organ-specific meridians and enhances parasympathetic activity and suppresses sympathetic activity. The aim of this review is to summarize and understand the effects of acupuncture on autonomic nervous system. Methods: We reviewed a total of 29 studies published from 2000 to 2010 searched by PueMed and various domestic oriental medicine journals to obtain acupuncture studies related with ANS. Each article was classified by ANS measurement index and reviewed for study objectives, outcomes, acupuncture points, experimental and control interventions. Results: In the study of acupuncture about EEG, HRV, SCR, the experiment results are not the same by acupoints. Although same acupoint the results differ by subject's condition. But the study showed some clear tendency. In brief, in normal states acupuncture enhanced either vagal or sympathetic tone depending on the stimulated acupuncture point sites. On the other hand, most of studies demonstrated that acupuncture restored the autonomic dysfunctions in various kinds of tired or stressful states. Conclusions: We reviewed studies that contributed to an understanding of the effects and mechanisms of acupuncture on autonomic nervous system. Although the relationship between acupuncture and ANS response is still uncertain, acupuncture could be a excellent treatment method for modulating autonomic dysfunction.

The purpose of this study was to examine the influence of the exercise performance of yoga and pilates on the autonomic nervous system in an effort to provide some clinical information on exercise prescription. The subjects were 20 selected college students who majored in P.E. A yoga group and a pilates group were organized with 10 students respectively, the autonomic nervous system of the students was measured before the exercise, immediately after that and 30 minutes after recovery. The findings of the study were as follows: First, there were significant differences in the yoga group's stress index and average pulse according to the main effect of the time and interaction effect between the time and group. Second, there were significant differences in the yoga group's sympathetic nervous system activity and autonomic nerve balance according to all the main effect of the time, interaction effect between the time and group and the main effect of group. Third, there were significant differences in HRV(Heart Rate Variability), parasympathetic nervous system activity, SDNN, and RMSSD according to the main effect of the time, and interaction effect between the time and group and the main effect of group produced no statistically significant differences. In conclusion, yoga seemed to be effective at lowering stress index and average pulse. Specifically, yoga exercise seemed to exert a more positive influence on the decrease of sympathetic nervous system activity and autonomic nerve balance than pilates exercise.
Objective : We investigated the effects of distilled Wild Ginseng Herbal Acupuncture on autonomic nervous system with the Heart Rate Variability(HRV) in adult man. as well as we tried to observe how distilled Wild Ginseng Herbal Acupuncture on the balance of the autonomic nervous system. Method : We investigated the effects of distilled Wild Ginseng Herbal Acupuncture on autonomic nervous system with the Heart Rate Variability(HRV) in adult man. as well as we tried to observe how distilled Wild Ginseng Herbal Acupuncture on the balance of the autonomic nervous system. 1 healthy volunteers consisted of 31 subjects in experiment(distilled Wild Ginseng Herbal Acupuncture) group and 30 subjects in control(Normal Saline) group. Study form was a randomized, placebo-controlled, double-blind clinical trial. 31 subjects in experiment group were injected distilled Wild Ginseng Herbal Acupuncture at $GB_{21}$(Kyonjong) and 30 subjects in control group were injected Normal Saline at $GB_{21}$(Kyonjong). except of 2 subjects(in control group) who can't be measured and 11 subjects(7 in experiment group and 4 in control group) who move or make unforceable error during measuring. Finally 24 subject in experiment group and 24 subject in control group are studied. We measured HRV by PolyG-I on 7 times : before and after injection per 5 minutes during 30 minutes. The SPSS 10.0 for windows was used to analyze the data and the paired t-test(in group) and Student t-test(between two groups) were used to verify the result. Result : 1. After distilled Wild Ginseng Herbal Acupuncture injection, Mean HRV is significantly low only for first 5 minute, SDNN is significantly high after 5 minute, Complexity is significantly low after 5 minute, HRV index is significantly high after 10 minute and pNN50 is significantly low after 5 minute. 2. SDNN of distilled Wild Ginseng Herbal Acupuncture Group significantly increased from 20minute to 25minute, and pNN50 of distilled Wild Ginseng Herbal Acupuncture Group significantly decreased from 10minute to 15minute and 20 minute to 30 minute compared with those of Normal Saline group. 3. After distilled Wild Ginseng Herbal Acupuncture injection, Ln(TP), Ln(VLF) and Ln(LF) are significantly high after 5 minute, normalized LF is significantly high after 5 minute and normalized HF is significantly low after 5 minute. 4. Ln(TP) and Ln(VLF) of distilled Wild Ginseng Herbal Acupuncture Group significantly increased from 20minute to 25 minute compared with those of Normal Saline group. Conclusion : The results suggest that distilled Wild Ginseng Herbal Acupuncture in healthy adult man tend to activate the autonomic nervous system and sympathetic nervous system compared to Normal Saline within normal range.
Objectives : Essential hyperhidrosis is a socially and occupationally disabling disorder. There are many suggestions that hyperhidrosis is associated with the autonomic nervous system. This study was designed to investigate the autonomic nerve system the patients with hyperhidrosis. Methods : 348 palmar and plantar hyperhidrosis patients and 20 systemic hyperhidrosis patients in the ambulatory care were investigated. All patients were inspected at the first medical examination, using the PSA of HRV. HRV was measured for 5 minutes after 5 minutes' bed rest. We checked the frequency domain analysis of HRV (i.e. TP, VLF, LF, HF and LF/HF) which were transformed into natural logarithm of patients against the standard measures of the HRV components. Then, we compared the means of patients with means and highest values of in the normal range of Koreans 1) between the patients with palmar and plantar hyperhidrosis and the healthy controls and 2) between the patients with the systemic hyperhidrosis and healthy controls, by the frequency domain analysis of heart rate variability (HRV), respectively. We then compared the results between 1) and 2). Results : The values of natural logarithmic measures of LF/HF ratio in the patients with palmar and plantar hyperhidrosis we examined were significantly higher than the values of healthy controls, but those in the patients with systemic hyperhidrosis were not higher. Conclusion : This study suggests that the autonomic nervous function did not simply increase but that the balance between sympathetic and parasympathetic nervous function did matter in patients with palmar and plantar hyperhidrosis. This balance included that the sympathetic nervous function aggravated comparatively with parasympathetic nervous function. On the other hand, we couldn't find any significance of the patients with the systemic hyperhidrosis as for the autonomic nervous function.

Objectives A normal circadian rhythm of autonomic nervous system function stands for the daily change of sympathetic and parasympathetic modulation, which can be measured by heart rate variability (HRV). Generally, patients in the intensive care unit (ICU) are prone to sleep-wake cycle dysregulation, therefore, it may have an influence on the circadian rhythm of autonomic nervous system. This study was designed to interpret possible dysregulation of autonomic nervous system in ICU patients by using HRV. Methods HRV was assessed every 3 hours in 21 ICU patients during a 7-minute period. The statistical differences of HRV features between the morning (AM 6 : 00-PM 12 : 00), and the afternoon (PM 12 : 00-PM 18 : 00) periods were evaluated in time domain and frequency domain. Results Patients showed significantly increased normalized power of low frequencey (nLF), absolute power of low frequencey (LF)/absolute power of high frequencey (HF) in the afternoon period as compared to the morning period. However, normalized power of high frequency (nHF) was significantly decreased in the afternoon period. There was no statistically significant difference between the morning period and the afternoon period in the time domain analysis. Conclusions The increased sympathetic tone in the afternoon period supports possible dysregulation in the circadian rhythm of autonomic nervous system in ICU patients. Future studies can help to interpret the association between autonomic dysregulation and negative outcomes of ICU patients.

We investigated the physiological patterns of cybersickness in a Virtual Reality(VR). Subject were exposed to the VR for 9.5 min, and required to detect specific virtual objects. Sixteen electrophysiological signals were recorded before, during, and after the virtual navigation. five questionnaires on the VR experience were acquired form 61 healthy subjects. During the virtual navigation, subjects with the high cybersickness susceptibility showed significant physiological changes, which included increased gastric tachyarrhythmia, eyeblink frequency, and EEG delta wave and decreased EEG beta wave. These results suggest that cybersickness may induce or accompany the changes in central nervous system and autonomic nervous system. Also, these results suggest that there may be increased sympathetic activation in autonomic drive for cybersickness.
Background : Phentermine classified by "sympathomimmetic amie", is a stimulant of sympatheic tone But there has been no concrete study which presents the influence of phentermine on autonomic nervous system. Analysis of Heart rate variability is reliable, non-invasive and very useful for evaluating function of autonomic nervous system. We tried to elucidate the influence of phentermine on autonomic nervovs system by heart rate variability. MethodsAmong the 70 candidates who participated in the double-blind case control study whichwas designed in purpose of approving whether- Adipekⓓ is effective for treatment of obesity, 45persons were folled up. From April, 2005 to May 2005, HRV of the candidates who takes phentermine or placebo for 1month, was recorded using BFM-5000ⓓ(medi-core) for 5 minutes in resting state. HRV measures were assessed by time-domain and by frequency- domain analysis. Time domain parameters contain SDNN(Standard Deviation of NN intervals) and RMSSD(Root-Mean-Square of Successive Differences), etc and frequency domain Parameters contain Total Power(TP), Low frequency(LF'0.04-0.15Hz) power. High Frequency(HF:0.15-0.4Hz) power and LF/HF ratio etc. Results: Intakes of phentermine reduce HRV significant1y. SDNN & RMSSD, the main tine domain parameters of HRV, were decreased significantly(P=0.007. 0.016). PSI(Physical Stress Index of Pressure Index) was increase significantly(P=0.002)The main frequency domain parameters(TP, LF & VLF), also decreased significantly. (P=0.024,0.033, 0.015)Conclusion: The result showed that intakes of phentermine reduce heart rate variability and influence on most parameters of HRV. So phentermine not only accelerates sympathetic tone, but also inhibit the balance and function of autonomic nervous system.
Hypertension is a medical problem with no permanent cure. Extended hypertension can cause various cardio vascular diseases, cerebral vascular diseases, and circulatory system trouble. Medical treatment at present does not consider circadian variation of blood pressure in patients ; therefore, the problem of over-reduction of blood pressure through drugs sometimes occurs. This paper presents a prediction model of circadian variation or moon blood pressure employing the endocrine grand and the autonomic nervous system.

Purpose: Premenstrual syndrome(PMS) is a collection of physical, psychological and emotional symptoms related to a women's menstrual cycle. The symptoms are related with Autonomic Nervous system. The purpose of this study is to investigate the activity of Autonomic Nervous system in women with premenstrual syndrome(PMS) by using Heart Rate Variability(HRV). Methods: We studied 26 patients visiting ㅇㅇ hospital from 26th December 2005 to 26th April 2006. Activity of Autonomic Nervous system was assesed by means of Heart Rate Variability(HRV). The subjects were categorized in two groups, PMS group(10) and non-PMS group(16). We studied the difference of HRV between two groups by Mann-Whitney U-test using SPSS for windows (version 12.0). Results: SDNN of PMS group was non-significantly lower than non-PMS group. RMS-SD of PMS group was significantly lower than non-PMS group. Mean PR of PMS group was non-significantly higher than non-PMS group. TP, VLF, LF, HF norm of PMS group was non-significantly lower than non-PMS group. HF of PMS group was significantly lower than non-PMS group. LF norm, LF/HF ratio of PMS group was non-significantly higher than non-PMS group. Conclusion: The results suggest that PMS can be related to decreased activity of parasympathetic nervous system. HRV can be useful to diagnose PMS. The more studies to diagnose PMS would be needed.
In addition to classic cholinergic and adrenergic pathways, the existence of a third division of autonomic control in the human airways has been proved. It is called a nonadrenergic noncholinergic(NANC) nervous system, and difficult to study in the absence of specific blockers. Neuropeptides are certainly suggested to be transmitters of this NANC nervous system. It is very frustrating to understand the pathophysiologic role of these peptides in the absence of any specific antagonists. However, further studies of neuropeptides might eventually lead to novel forms of treatment for bronchial asthma. Another study of the interaction between different components of the autonomic nervous system, either in ganglionic neurotransmission or by presynaptic modulation of neurotransmitters at the end-organ will elute neural control in airway disease, particularly in asthma. Studies of how autonomic control may be disordered in airway disease should lead to improvements in clinical management. Epithelial damage due to airway inflammation in asthma may induce bronchial hyperresponsiveness. Axon reflex mechanism is one of possible mechanisms in bronchial hyperresponsiveness. Epithelial damage may expose sensory nerve terminals and C-fiber nrve endings are stimulated by inflammatory mediators. Bi-directional communication between the nerves and mast cells may have important roles in allergic process. The psychological factors and conditioning of allergic reactions is suggested that mast cell activation might be partly regulated by the central nervous system via the peripheral nerves. Studies in animal models, in huamn airways in vitro and in patients with airway disease will uncover the interaction between allergic disease processes and psychologic factors or neural mechainsms.
