  • The purpose of this study is to explore the effects of Chamaecyparis obtusa essential oil on the activity of autonomic nervous system. Heart rate variability (HRV), as an indicator of autonomic nervous system activity and blood pressure were measured before and after inhalation of Chamaecyparis obtusa essential oil. The systolic blood pressure was decreased by inhalation of Chamaecyparis obtusa essential oil (p<0.05). The diastolic blood pressure was not changed significantly by Chamaecyparis obtusa. High frequency (HF) power level was not changed but High frequency/Low frequency (HF/LF) ratio was decreased by Chamaecyparis obtusa essential oil (p<0.05), meaning that parasympathetic nervous system activity was not affected but sympathetic nervous system activity was decreased. These results indicate that Chamaecyparis obtusa essential oil has a modulatory effect on the autonomic nervous system activity.

  • This study was designed to clarify the effect of juniper essential oil on the autonomic nervous system. Blood pressure and heart rate variability (HRV) reflecting autonomic nervous system activity were measured. The systolic and diastolic blood pressure were decreased by inhalation of juniper essential oil. High frequency (HF) power level, an indicator of parasympathetic nervous system activity was increased in the stimulation of juniper essential oil. High frequency/low frequency (HF/LF) ratio, an indicator of sympathetic nervous system activity was decreased by the juniper essential oil. These results suggest that juniper essential oil has a modulatory effect on the autonomic nervous system activity.

  • Globally, civil infrastructures are deteriorating at an alarming rate caused by overuse, overloading, aging, damage or failure due to natural or man-made hazards. With such a vast network of deteriorating infrastructure, there is a growing interest in continuous monitoring technologies. In order to provide a true distributed sensor and control system for civil structures, we are developing a Structural Nervous System that mimics key attributes of a human nervous system. This nervous system is made up of building blocks that are designed based on mechanoreceptors as a fundamentally new approach for the development of a structural health monitoring and diagnostic system that utilizes the recently developed piezo-fibers capable of sensing and actuation. In particular, our research has been focused on producing a sensory nervous system for civil structures by using piezo-fibers as sensory receptors, nerve fibers, neuronal pools, and spinocervical tract to the nodal and central processing units. This paper presents up to date results of our research, including the design and analysis of the structural nervous system.

  • Purpose: This study was to identify the effects of laughing and music therapy on depression and the activities of the autonomic nervous system in the elderly with dementia. Methods: The participants were 61 seniors over 65 years old with dementia, admitted to nursing homes. Twenty of them received laughing therapy, 21 received music therapy and 18 were in the control group. A total of 59 patients' data were analyzed. Depression was measured by Cornell Scale for Depression in Dementia tool, and the activities of the autonomic nervous system by the heart rate variability measuring device. The data were analyzed by frequency and percentage, Chi-square test, t-test, ANOVA, and Tukey test. Results: The depression of the music therapy group was more significantly decreased than the laughing therapy group and the control group. The activities of the autonomic nervous system of the laughing therapy group were more significantly increased than the music therapy group. The magnitude of the activities of the autonomic nervous system of the laughing therapy group were more significantly increased than the music therapy group. Conclusion: This study showed that music therapy was more effective than laughing therapy for the decrease of depression. Laughing and music therapy were more effective than in the control group for increasing the activities of the para-sympathetic nervous system and decreasing the activities of the sympathetic nerve system.

  • Chromosomal region maintenance 1 (CRM1) is associated with an adverse prognosis in glioma. We previously reported that CRM1 inhibition suppressed glioma cell proliferation both in vitro and in vivo. In this study, we investigated the role of CRM1 in the migration and invasion of glioma cells. S109, a novel reversible selective inhibitor of CRM1, was used to treat Human glioma U87 and U251 cells. Cell migration and invasion were evaluated by wound-healing and transwell invasion assays. The results showed that S109 significantly inhibited the migration and invasion of U87 and U251 cells. However, mutation of Cys528 in CRM1 abolished the inhibitory activity of S109 in glioma cells. Furthermore, we found that S109 treatment decreased the expression level and activity of MMP2 and reduced the level of phosphorylated STAT3 but not total STAT3. Therefore, the inhibition of migration and invasion induced by S109 may be associated with the downregulation of MMP2 activity and expression, and inactivation of the STAT3 signaling pathway. These results support our previous conclusion that inhibition of CRM1 is an attractive strategy for the treatment of glioma.

  • Objectives: Recently, many studies have reported beneficial effects from the application of laser and light-emitting diode (LED) therapy for cerebral nervous disease. Transcranial laser therapy and LED therapy may be an effective method to treat diseases of the cerebral nervous system. This study aims to discuss the possibility of laser and LED therapy for cerebral nervous disease by reviewing literature about its effectiveness. Methods: We searched papers using PubMed, Science Direct, CINAHL, KTKP, Oasis and NDSL, using the keywords "Laser therapy, low-level", "Transcranial laser", "Transcranial light emitting diode" and "stroke", "traumatic brain injury", "dementia", "anxiety", "cognitive", "emotional effects", "psychiatric disorder", "multiple sclerosis", "Parkinson's disease". The search range included randomized controlled trials (RCTs) and clinical case series. Reviews and animal experiments were not included. Studies not matched with inclusion criteria were excluded. Results: A total 1,119 studies were found. 1,100 were excluded from scanning titles and abstracts and finally 9 articles were selected. Among the 9 articles, 5 were RCTs, one was a controlled study, and the other 3 were case reports. They reported that transcranial laser therapy and LED treatment had beneficial effects from photobiomodulation to the cerebral nervous system. Clinical evaluation factors showed favorable trends. Conclusions: Transcranial laser therapy and LED therapy seem to be effective to the cerebral nervous system and they may be a favorable choice for cerebral nervous disease.

  • PURPOSE: The purpose of this study is to investigate the effect of the physical therapy treatment room environment using microwave diathermy on the autonomic nervous system of human body. METHODS: Participants were 24 healthy adults. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences(RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were compared in microwave irradiation and non-irradiation group. Data were analyzed in Wilcoxon's signed-ranks test and Mann-Whitney U test. RESULTS: Standard deviation of all normal R-R intervals (SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different in microwave irradiation group. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different in microwave non-irradiation group. Standard deviation of all normal R-R intervals(SDNN), root mean square of successive differences (RMSSD), low frequency(LF), high frequency(HF), LF/HF ratio were not significantly different between two groups. CONCLUSION: There was no significant change in the sympathetic nervous system and parasympathetic nervous system regardless of the presence of microwave irradiation. There was no significant change in the autonomic nervous system adaptability regardless of the presence of microwave irradiation.According to this study, microwave diathermy does not have significant effect on the autonomic nervous system.Future study is necessary to investigate the long term effect of the physical therapy treatment room environment using microwave diathermy on the autonomic nervous system of the human body.
