  • The purpose of this study were to investigate influence of heat stress temperature on sympathetic nerve activities. Subjects were 8 normal adults (4 men, 4 women, 21.36 years old). First sympathetic nerve activities were measured at the point that increase of core temperature stops at the state of applying normal thermic temperature (NIT; $34^{\circ}C$). After measurement, temperature of bathtub was increased to heat stress temperature (HST; $46^{\circ}C$) and sympathetic nerve activities were remeasured at the point that temperature increase stops. Sympathetic skin response (SSR) were analyzed using EMG, IR thermometer, and auto stethoscope. SSR latency showed significant differences at both palms by electrical stimulation to median nerve (p<.05). Electrical stimulation to forehead showed significant difference at left palm (p<.05) and electrical stimulation to navel showed significant difference at right palm (p<.05). Median nerve in changes of SSR amplitude showed significant differences at both palms in HST (p<.01). Electrical stimulation to navel showed significant difference at left palm (p<.05). Ts of forehead and xiphoid process showed significant differences (p<0.01). Tc of oral (p<0.05) and inner ear (p<0.01) showed significant differences. Pulse rate showed significant difference (<0.05). This study showed that immersion in HST had significant decrease of excitability in sympathetic nervous system compared to immersion in NTT.

  • Purpose: The purpose of this study was to investigate the change in sympathetic nervous system responses of healthy adult women with changes in stimulus intensity of high frequency transcutaneous electrical nerve stimulation. Methods: Twenty-four healthy subjects (women) received high frequency electrical stimulation of the forearm. The subjects were randomly assigned to one of two groups; a low intensity stimulation group (n=12) and a high intensity stimulation group (n=12). The electrode attachment was arranged on the forearm of the dominant arm and the electricity stimulus time was 20 minutes. Measured items included skin conductance, pulse rate, skin temperature, and respiration rate. Each was measured at 4 times. Results: Skin conductance and skin temperature showed significant group by time interactions, though there were no significant group and time effects. There were no significant differences according to time, group effect, and a group by time interaction in pulse and respiration rates. Conclusion: High frequency and high intensity electrical stimulation may be helpful for the improvement of sudomotor function through the activation of the sympathetic nervous system. Also, high frequency and low intensity electrical stimulation may be helpful for the reduction of sudomotor function via inhibition of the sympathetic nervous system.

Sympathetic Nerve Function to Electrical Response of Ryodoraku Point and Disarrangement of its Meridian Location on the Anatomical Viscera Exclude the Association between Ryodoraku Theory and Meridian Principle (양도점의 전기적 반응에 대한 교감신경작용과 경락 배열과 실질장기의 불일치는 양도락의 경락 관련성을 배제한다.(위 운동장애형 기능성 소화불량증 환자의 양도점 H4,5,6의 반응을 중심으로))

  • Objectives : The purpose of this study was to investigate two subjects: the diagnostic value of bilateral lowering of electrical activity at point H4,5,6 of Ryodoraku and the mechanism for Ryodoraku phenomena. Methods : Electrical activities of Ryodoraku test and electrogastrography recorded simultaneously and monitored continuously from 16 cases of functional dyspeptic patients were collected and their variations were grouped by the topics of discussion which were peculiarity, stability, lagging, alterability, and anomaly. Ryodoraku recordings obtained from 6 patients with different gastrointestinal diseases and 1 normal healthy person were used as control. The results are discussed with Nakatani's suggestion, theory of sympathetic nerve and Meridian Principle, respectively. Finely, coincidence of stomach arrangement between anatomy and meridian system in Ryodoraku was also evaluated. Results : Time-course variation showed a regular relationship between the typical pattern of Ryodoraku at point H4,5,6 and gastric myoelectrical activity. However, an irregular relationship and atypical pattern of Ryodoraku occasionally appeared. A literature search suggested that electrical response at the Ryodoraku point H4,5,6 may be dependent on an afferent sympathetic spinal reflex transmitted from the stomach. However, there was no evidence for making clear whether bilateral lowering of electrical activity at this point was induced by hypofunction of local sympathetic nerve in the skin itself or of signals transmitted from the gastric sympathetic nerve or not. The coincidence of 19% could not provide a visceral arrangement of the stomach between anatomy and meridian systems. Conclusions : Bilateral lowering of electrical activity at Ryodoraku point H4,5,6 has value as a diagnostic index for gastric dysmotility of functional dyspepsia. This phenomenon is associated with spinal reflex transmitted from the afferent sympathetic nerve in the stomach but not that of meridian function.

  • This study compared the heart rate variability tests of healthy college students and chronic fatigue patients for 2 years. Study subjects were idiopathic chronic fatigue patients who carried out the HRV tests and students conducted HRV test when health screening test. Study subjects were 250 people, 104 people and men (41.6%), women were 146 patients (58.4%). In patient group, the autonomic nervous system activity was decreased, the activity of the sympathetic nerve and the parasympathetic nerve were significantly reduced compared to the control group(Patient:84.17±16.27, Control:98.33±17.28). Regardless of gender, patient group's autonomic nervous system activity was decreased, the activity of the sympathetic nerve and the parasympathetic nerve were significantly reduced, compared to the control group(Patient Female:84.17±16.27, Patient Male:84.07±14.96/Control Female:98.33±17.28, Control Male:96.45±16.92). Even though same ages, patient group's autonomic nervous activity was reduced compared to control group(Patient:89.36±12.43, Control:97.39±16.91). Fatigue patients' activity of the sympathetic nerve and the parasympathetic nerve were significantly reduced, regardless of the fact that activity of the sympathetic nerve is increased and the parasympathetic nerve is decreased in stress state like an impassioned injury(七情傷). Therefore HRV test is useful to diagnose Fatigue from this study.

  • This study was designed to research whether Dinamika can yield a suitable diagnosis for Activity of Autonomic Nene System on stroke. The testing of Dinamika was carried out at Oriental Medical Centar of Dong-Eui University with the participation of 27 patients. The results of Dinamika examinations shows as follows : Group A(the rising of a parasympathetic nerve system) is 0 persons. And Group B(the balancing autonomic none system) is 4 persons. Group C(the rising of a sympathetic nerve system) is 23 persons. There are 7 persons that it is difference of more than $20\%$ between B1 (the control ability of autonomic nerve system) and B2(the potential energy to control autonomic nerve system), 11 person that B1 and B2 are less than $10\%$, 1 person that B1 and B2 are balanced about $60\%$, 8 person that it is balanced domain from $10\%\;to\; 60\%$ between B1 and B2. According to this study on activity of autonomic nerve system using Dinamika on Stroke, these results suggest that 27 patients evidence the problem of autonomic none systems.

  • 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.

  • Objectives : Increasing evidence suggests that parasympathetic vagus nerve activity plays a role in modulating acupuncture-induced anti-inflammatory reaction, but the function of sympathetic nerve is not known. Here, we investigated whether splanchnic sympathetic nerve activity was involved in the regulation of splenic expression of $TNF-{\alpha}$ mRNA by electroacupuncture (EA) in LPS-injected animals. Methods : DiI was injected into the stomach or celiac ganglion (CG) for retrograde labeling of the target tissues. EA was given at ST36 and the electrical stimulation on the sciatic nerve in LPS-injected mice. c-Fos signals in the tissues were analyzed by immunofluorescence staining, and $TNF-{\alpha}$ mRNA was analyzed by real-time PCR. Results : Application of EA at ST36 or electrical stimulation on the sciatic nerve induced c-Fos expression in neurons of the spinal cord and celiac ganglion (CG). Then, the vagotomy reduced c-Fos levels in CG neurons but not in the spinal cord in animals given EA. Expression of $TNF-{\alpha}$ mRNA which was induced in the spleen after LPS was significantly inhibited by EA, then the vagotomy elevated $TNF-{\alpha}$ mRNA level similar to that in LPS-injected animals. Splanchnectomy in animals given LPS and EA also increased $TNF-{\alpha}$ mRNA though it was less effective than vagotomy. Conclusions : Our data suggest that EA delivered to the spleen via the splanchnic sympathetic nerve may be involved in attenuating splenic inflammatory responses in LPS-injected animals.

  • This study is to investigate the effects of manual lymphatic drainage of stressed hospital office employees on the autonomic nervous. A total of 30 stressed hospital office women voluntarily participated in the study. The participants were randomized to the manual lymphatic drainage groups and rest groups. The intervention was conducted for 20 minutes in each group. There were significant differences in sympathetic nerve, parasympathetic nerve, and pain within manual lymphatic drainage groups(p<.05). There were significant differences between groups for the sympathetic nerve, parasympathetic nerve, and pain(p<.05). Therefore, manual lymphatic drainage is an effective intervention for reducing the stress and pain of stressed hospital office employees.

  • Stress reaction can be shown widely in the systems of psychology, endocrinology, immunology and so on. Stress promotes catecholamine from the autonomic nerve system, and this activates the sympathetic nerve system. As the sympathetic nerve system is activated, high blood pressure, tachycardia, vertigo, anxiety, diaphoresis, myotonic reaction and others can happen. Autonomic imbalance is the syndrome that people suffer from various symptoms accompanying no organic lesions and no psychological disorders by losing the hormonies between the sympathetic and parasympathetic nerve system. We experienced a 55 year-old female who complained of sudden abdominal pain after being frightened at trouble with her husband. Her abdominal pain was very characteristic, "Something is like rising in my abdomen.", that occurred several times a day. We diagnosed 'Bun-Ton Disease' from her abdominal sign. Several oriental medicine books recorded aspects of Bun-Ton disease and treatments, we had given herbal medicine and treated acupuncture be based on those. Results from studies to date suggest the Bun-Ton Disease's main cause is fright or shock, and they stimulate releasing epinephrine or norepinephrine, that result in various symptoms. In this case report, we will present this patient's case and review the Bun-Ton Disease.
