Objectives: To characterize autonomic dysfunction in patients with Cold hypersensitivity, their heart rate variability(HRV) were measured and analyzed with cold hypersensitivity patients, compared with those of normal population. Methods: We studied 56 patients visiting Gangnam Kyung-hee korean hospital from 1st January 2010 to 31th December 2010. Heart rate variability were obtained from 28 female patients who suffer from cold hypersensitivity and 28 healthy female controls in resting state. We studied the difference of Heart rate variability between two groups by Independent T-test using SPSS for windows(version 17.0). Results: Standard deviation of NN interval(SDNN), total power(TP), Very low frequency(VLF) in patients with cold hypersensitivity were significantly different with those of controls. While no significant differences were observed in square root of mean squared differences of successive NN intervals (RMSSD), low frequency (LF) and high frequency(HF). Conclusions: The decreased values of heart rate variability(HRV) study means that they may have some kinds of imbalance in autonomic nervous system in cold hypersensitivity patients. heart rate variabiliry(HRV) study might be a tool of diagnosis and predictors in cold hypersensitivity patients.

Objective : The study aims to investigate the effect of moxibustion treatments on autonomic nervous system function of cancer patients through the evaluation of heart rate variability (HRV) biofeedback testing. Materials and Methods : Six cancer patients from inpatient care unit of Dunsan Oriental Hospital, Daejeon University were given three moxibustion treatment sessions every other day over one week period on five Oriental Medicine meridian points CV4, CV6, CV12, KD1, and PC8. HRV biofeedback was conducted before and after each treatment sessions. Three areas of analyses were done from the test conducted; Time Domain Analysis, Frequency Domain Analysis and Autonomic Nervous System (ANS) balance analysis. Results : Time Domain Analysis has shown increased Standard Deviation of all Normal R-R Intervals (SDNN), and decreased Mean Heart Rate and Physical Stress Index (PSI) levels, with statistical significance (P<0.05). In Frequency Domain Analysis, series of moxa treatments have increased Total Power (TP), Very Low Frequency Oscillation Power (VLF), High Frequency Oscillation Power (HF), normalized HF values while decreasing Low Frequency Oscillation Power (LF), normalized LF and LF/HF ratio with statistical significance (P<0.05). The values of ANS activity, ANS balance, Stress resistance, Stress index, have also shown significant changes. For cardiac stability stroke volume power (SP) and Blood Vessel Tension (BVT) were followed, which were both increased after treatment. All changes were statistically significant (P<0.05). Conclusion : The results have shown a positive correlation between the moxibustion treatments and autonomic nervous system responses on cancer patients through the HRV biofeedback testing. This study suggests possible application of moxibustion treatments for managing ANS functions of cancer patients, although additional studies with larger population are necessary to confirm the data.

Objectives: This study was performed to investigate the effect of hot spring therapy on children weight, body composition and heart rate variability. Methods: The study was carried out from 30 children who visited the spa from August 1, 2011 to August 31, 2011. We measured the change of weight, body composition, and heart rate variability after hot spring therapy for an hour per day. Results: The subject was consisted of 13 boys and 17 girls. This study revealed that their weight got lost from a hot spring therapy, which was statistically significant. Their body mass index(BMI) was decreased in from a hot spring therapy, which was not statistically significant. Total body water, muscle, protein, and mineral were decreased from a hot spring therapy, which was statistically significant. We measured HRV(heart rate variability) before and after the hot spring therapy. The mean HRT was increased, which was statistically insignificant. SDNN(standard deviation of the NN interval) and RMSSD(square root of the mean of the sum of the square of differences) were not different before and after the hot spring therapy. ln TP was decreased insignificantly. ln VLF was not affected before and after hot spring therapy. ln LF and ln HF was decreased, LF norm was increased, and HF norm was decreased, which were not statistically significant. Also, LF/HF ratio was increased insignificantly. Conclusions: From these results, we concluded that the weight, total body water, muscle, protein, and mineral got lost from the hot spring therapy. However, the HRV was not affected from the hot spring therapy.

Objective : This research was designed to study the characteristics of heart rate variability in postpartum women compared with normal women. Method : HRV data of postpartum women were gathered from 255 women who was hospitalized for oriental postpartum treatments(Age : 25-35). HRV data of comparison group were gathered from 327 women who visited hospital to check up their health(Age : 25-35). The SPSS 12.0 for windows was used to analyze the date and the independent samples t-test was used to verify the result. Result : 1. Mean-RR and SDNN of postpartum women group significantly decreased compared with that of normal women group. But, Heart Rate of postpartum women group significantly increased compared with that of normal women group. 2. HRV-Index, RMSSD and SDSD of postpartum women group significantly decreased compared with that of normal women group. pNN50 of postpartum women group significantly increased compared with that of normal women group. 3. Ln(TP), Ln(VLF), Ln(LF) and Ln(HF) of postpartum women group significantly increased compared with that of normal women group. 4. There were no significant differences in Normal LF, Normal HF and LF/DF Ratio between postpartum women group and normal women group. Conclusion : The result suggest that the function of heart of postpartum women group significantly decreased compared with that of normal women group. Futhermore although the ANS maintained the balance in the range of normality, the sympathetic nervous system frequently revitalized which caused increasing the heart of pulsation.

Objective : There have been few comprehensive studies on the analysis of 24-hour HRV of major depressive disorder (MDD). The purpose of this study was to compare the autonomic nerve system of patients with a MDD with healthy patients and to examine the physiologic and clinical effects of 24-hour HRV by analyzing whether the HRV demonstrates the level of depressive symptoms after improving the symptoms in patients with a MDD. Methods : The 24-hour HRV was measured in patient groups with a MDD (n=16) and control groups (n=16). The patients with a MDD received the follow up test for two months after the treatment. Results : There were significant differences among the indexes (SDNN, rMSSD, SDNN index, and pNN50) of time-domain analysis and the indexes (TP, VLF, LF, HF, and ULF) of frequency-domain analysis of HRV between patient and control groups. The means of RR, SDNN, SDANN, and TP increased after two month of the treatment, comparing them with before the treatment, but there were no statistical significance. Conclusion : The results of 24-hour HRV analysis indicated significant decrease of HRV indexes among MDD patients which may suggest decrease of parasympathetic nervous functions.

Objectives : Chronic pain affects and is affected by physical and psychosocial factors. It also has a complicated and indefinite mechanism. This research is for clarifying relations with chronic pain, stress, and autonomic nerve system by comparing HRV and Stress Reaction Index(SRI) of chronic pain patients with those of acute pain patients. Methods : The subjects were 32 patients who visited Kangnam Kyunghee Hospital for nuchal pain or low back pain treatment from March 2008 to September 2008. Among them, 16 patients who suffered over 6 months are classified chronic pain group and 16 patients who suffered under 6 months as acute pain group. All subjects had their HRV(SA-2000E: Medicore Co..Ltd. Korea) and SRI measured at first visit. We studied the difference of HRV between two groups.(Statistics by Student t-test, p<0.05) Results : R-MSSD, TP, VLF, LF, HF and LF/HF ratio of the chronic pain group were significantly lower than those of the acute pain group. Compared with those of the acute pain group, total SRI of the chronic pain group were low but it's not significant except frustration. Conclusion : The results of HRV of the chronic pain group patients show that chronic pain is related to psychosocial factor and autonomic disturbance.

The use of the geophysical method in mining prospecting has been studied in the Asdaf region (South-East of Morocco). The objective of the study is to examine the aptitude of the electrical technique, in this case induced polarization (IP) and electric tomography, combined with the electromagnetic method (VLF), in the exploration of barite . The result obtained by the pseudo-sections of electrical tomography and that of KH filtration highlighted anomalies of resistant contact (greater than 400Ω.m) and of high charge chargeability (5mV / V). These contacts are hosted in less resistant Devonian age shale and sandstone. The resistivity response obtained at their level is characteristic of the venous structures associated with barite mineralization. The direction of the mineralized veins is parallel to the direction of the fractured zones (NE-SW), which indicates that the mineralization in place is due to the tectonic movements of the Hercynian orogeny (from Devonian to Permian). These veins are aligned with the locations of abandoned mine shafts and with surface mining areas. Geophysical technique therefore seems to play a key role in barite mining exploration.

Objectives : To study autonomic nervous system dysfunction of Low Back Pain(LBP) patients, using spectral analysis of Heart Rate Variability(HRV). Methods : HRV of 190 patients was measured and seperated into two groups, those with LBP(n=95) and healthy controls(n=95). HRV was measured by SA-6000(Medicore, Korea) for 5 minutes after 5 minutes' resting. Results : 1. Mean heart rate(MHRT) of the experimental group was slightly higher than that of the control group, but did not show significant difference(P=0.428). The square root of the mean squared differences of successive normal-to-normal intervals(RMSSD), logarithmic very low frequency power(Ln VLF) and low frequency power/high frequency power ratio(LH/HF ratio) were not significantly low between experimental group and control group(P=0.16, 0.130, 0.537). 2. The standard deviation of all the normal-to-normal intervals(SDNN), logarithmic total power(Ln TP), logarithmic low frequency power(Ln LF) and logarithmic high frequency power(Ln HF) were significantly low between experimental group and control group(P=0.03, 0.005, 0.001, 0.007). 3. Ln LF of acute group was significantly low compared with those of chronic group(P= 0.039). Conclusions : This study suggests the activity and imbalance of autonomic nervous system in LBP is low. Also sympathetic nervous system of acute LBP is lower than that of chronic LBP. Further study of HRV related to LBP is needed in the clinical medicine.
