Objectives : Since the Front Points are treated as response zone, it can be used for the diagnosis and treatment of disease in viscera and bowels. Jeonjung($CV_{17}$) is the Front Point of SIMPO, it is related with cardiovascular, neuro-psychiatrical disease in aspect of Oriental Medicine. This research is for clarifying relations with palpation of the Jeonjung($CV_{17}$) and autonomic nerve system by comparing HRV and SRI(Stress Reaction Index). Methods : This study was proceeded for three months, from June 2009 to September 2009. Among 31 healthy volunteers, 13 subjects who complained the pressure pain around Jeonjung($CV_{17}$) are classified pressure pain group and 18 subjects who had no pain around Jeonjung($CV_{17}$) as normal group. All subjects had their HRV(SA-2000E: Medicore Co..Ltd. Korea) and SRI measured at visit. We studied the difference of HRV between two groups.(Statistics by Student t-test, p<0.05) Results : LF normalization of the pressure pain group were significantly higher than those of the normal group. HF normalization of the pressure pain group were significantly lower than those of the normal group. Compared with those of the normal group, total SRI of the pressure pain group were low but it's not significant. Conclusions : The results of HRV of the pressure pain group show that pressure pain around Jeonjung($CV_{17}$) is related to mental stress and autonomic disturbance.

Objectives : The purpose of this study was to investigate differences between traffic accident and non-traffic accident patients in the early stage, by analysis of the heart rate variability(HRV) and visual analogue scale(VAS). Methods : This study carried out on 38 patients who complained of nuchal or lower back pain. They have received hospital treatment in Dae-Jeon Univ. Cheonan Oriental Hospital. In the TA(Traffic accident) group, the pain caused by TA and in non-TA group, the pain caused by other reasons. We measured HRV and VAS twice(pre-treatment(Tx.) and post-Tx.). Then we analyzed the data. Results : As time goes by, patients who complained of pain showed the inclination to improve ability to balance autonomic nerve system. And fatigue and pain were improved. But they showed the inclination to increase stress index. At pre-Tx., TA group had more stress and worse ability to balance autonomic nerve system, but showed lower fatigue index than non-TA group. But, as time goes by, in TA group the fatigue and autonomic balance got worse. At pre-Tx., non-TA group complained of more severe pain than TA group, but at post-Tx., TA group complained of more severe pain than non-TA group. In other words, in TA group, the decreasing rate of pain was lower than non-TA group. Conclusions : Results from this investigation showed that TA have a negative effect on stress index, ability to balance autonomic nerve system, fatigue index and decreasing rate of pain. These results are expected to consider characteristics of patients who complained of pain caused by TA.

This paper reviews the main aspects of cardiovascular system dynamics with emphasis on modeling hemodynamic characteristics using a lumped parameter approach. Methodological and physiological aspects of the circulation dynamics are summarized with the help of existing mathematical models: The main characteristics of the hemodynamic elements, such as the heart and arterial and venous systems, are first described. Lumped models of micro-circulation and pulmonary circulation are introduced. We also discuss the feedback control of cardiovascular system. The control pathways that participate in feedback mechanisms (baroreceptors and cardiopulmonary receptors) are described to explain the interaction between hemodynamics and autonomic nerve control in the circulation. Based on a set-point model, the computational aspects of reflex control are explained. In final chapter we present the present research trend in this field and discuss the future studies of cardiovascular system modeling.

Objectives This study was designed to identify the changes of autonomic nervous system (ANS) which was induced by acupuncture at the field of the auricular branch of the vagus nerve. Methods 30 healthy adults were selected and classified into two groups; experimental group, control group. After providing mental stress, acupuncture was applied at external ear in experimental group and no treatment executed in control group. The evaluation of ANS function was measured by heart rate variability (HRV). We statically analyzed the difference of HRV parameters which include mean heart rate (MHRT), standard deviation of all N-N intervals (SDNN), square root of the mean of the sum of the squares of differences between adjacent N-N intervals (RMSSD), total power (TP), low frequency power (LF), high frequency power (HF), LF/HF ratio. Results All subjects showed significant increase in SDNN, LF after stress stimulation (p<0.05). Immediately after intervention, MHRT was significantly decreased (p<0.001) and RMSSD, HF were significantly increased in experimental group (p<0.05). After the end of intervention, SDNN, HF, RMSSD, TP, LF were significantly increased in experimental group (p<0.01, p<0.05). And when comparing baseline HRV, SDNN, LF were significantly increased in control group (p<0.01) and SDNN, RMSSD, TP, LF were significantly increased in experimental group (p<0.05). In the subgroup analysis, normal balance of ANS group showed significant increase in TP, LF, SDNN, HF (p<0.01, p<0.05). Conclusions We suggested that acupuncture at external ear, region of the vagus nerve distribution could increase parasympathetic activity and cause changes and reregulation of the ANS.

Objectives: The purpose of this study is to report a case series of advanced cancer patients whose cancer pain was relieved by using autonomic nerve pharmacopuncture (ANP) treatment. ANP is a subcutaneous injection therapy of mountain ginseng pharmacopuncture (MGP) along the acupoints on the spine (Hua-Tuo-Jia-Ji-Xue; 0.5 cun lateral to the lower border of the spinous processes of vertebrae) to enhance the immune system and to balance autonomic nerve function. Methods: Patients with three different types of cancer (gastric cancer, lung cancer, colon cancer with distant metastases) with cancer pain were treated with ANP. 1 mL of MGP was injected into the bilateral Hua-Tuo-Jia-Ji-Xue on the T1-L5 sites (total 12-20 mL injection) of each patient's dorsum by using the principle of symptom differentiation. During ANP treatment, the visual analogue scale (VAS) for pain was used to assess their levels of cancer pain; also, the dosage and the frequency of analgesic use were measured. Results: The cancer pain levels of all three patients improved with treatment using ANP. The VAS scores of the three patients decreased as the treatment progressed. The dosage and the frequency of analgesics also gradually decreased during the treatment period. Significantly, no related adverse events were found. Conclusion: ANP has shown benefit in controlling cancer pain for the three different types of cancer investigated in this study and in reducing the dosage and the frequency of analgesics. ANP is expected to be beneficial for reducing cancer pain and, thus, to be a promising new treatment for cancer pain.

Tension headache is one of the most common form of headache. It may occur at any age, but is most common in adult and adolescents. One cause of this muscle contraction is a response to stress that induces changes and imbalance on autonomic nerve system. To cure tension headache, getting rid of psychological stress and anxiety have to do first. In this case, we described a 42 years old woman who diagnosed as tension headache. She complained headache with scruff pain, dyspepsia, nausea and coldness of toes. through oriental medical treatment(for example, acupuncture, herbal medicine ect.), her condition was improved.

Objectives: This research was designed to study the characteristics of heart rate variability in acute dyspepsia patients compared with normal group. Methods: The testing of HRV was carried out at Oriental Medical Center of ${\bigcirc}{\bigcirc}$University with the participation of 94 acute dyspepsia patients and 85 control group people. We checked HRV of the 2 groups that were checked on the first visit day and compared HRV index between groups. Results: In the frequency domain analysis, HF, LF, VLF, LF/HF ratio, TP were significantly lower than control group on acute dyspepsia patient group. HF, LF, VLF, LF/HF ratio, TP were not significantly associated with age. Conclusions: According to this study, autonomic nerve system was more decreased on the acute dyspepsia patient group compared with the control group. Though further studies will be needed, the present finding provide us the possibility that stress is a major cause of the acute dyspepsia along with food factor.

There is substantial evidence that anatomical connections and functional interactions exist between vestibular and autonomic systems. Heart rate variability (HRV) including mean, standard deviation, coefficient of variation (CV), power spectrum was analyzed for evaluation of the physiological role of the vestibular system on control of heart rate in rabbits. In anesthetized rabbits, electrical stimulation of the vagus nerve decreased heart rate and decreased LF/HF by increasing HF. On the cervical sympathetic nerve increased heart rate and increased LF/HF by increasing LF. Atropine, cholinergic blocker, increased heart rate and increased LF/HF by reducing HF, and propranolol, ${\beta}$-adrenergic blocker, decreased heart rate and decreased LF/HF by reducing LF> In unanesthetized rabbits, stimulation of the vestibular system induced by rotation or caloric increased heart rate and increased LF/HF by increasing LF> Also electrical stimulation of the vestibular nerve produced the same of effects as rotation or caloric in anesthetized rabbits. These results suggest that Stimulation of the vestibular system increased heart rate not by inhibiting the parasympathetic nerve but by activating the sympathetic nerve.
