Objective : Lithium inhibits the action of inositol monophosphatase(IMPase) in phosphoinositide(PI) signal transduction system at therapeutically relevant concentration. The depletion of inositol by lithium itself cannot explain the lithium's therapeutic effect. However, attention has focused on the abnormality of PI signal transduction system as the pathophysiology of bipolar affective disorder(BPD). We investigated whether IMPase mRNA levels of lymphocytes would be different between BPD patients(n=16) and age, sex-matched normal controls(n=16). We also investigated the change of IMPase mRNA level by lithium during 4 weeks to probe the possibility that IMPase mRNA levels could predict the therapeutic response to lithium and clinical course. Method : Relative IMPase mRNA levels in lymphocyte were quantified by reverse transcriptase(RT)-PCR in sixteen drug-free BPD patients and sex, age-matched normal controls. The psychopathology of patients were measured using YMRS (Young Mania Rating Scale) and CGI(Clinical Global Impression). Results : There was no significant difference in IMPase mRNA levels between BPD patients and normal controls. And the IMPase mRNA levels were not significantly changed by 4 week treatment with lithium. However, the basal IMPase mRNA levels were negatively correlated with the changes of CGI after 4 weeks. Furthermore, the patients with relatively high basal IMPase mRNA levels showed much more improvement during 4 weeks. Conclusions : BPD patients and normal controls were not distinguished by lymphocyte IMPase mRNA level. Although we do not support the hypothesis that lymphocyte IMPase activity would be related with the pathogenesis of BPD and the action of lithium, these data raise the possibility that lymphocyte IMPase mRNA levels could function as a predictor of therapeutic response and clinical course of BPD.

Objectives: Through comparing sleep variables and autonomic activities among three shifts in shift workers, the authors intended to clarify which shift is most tolerable and to identify the characteristics of their psychological and physical problems. This study is also expected to help shift workers to adapt themselves to their work more effectively. Methods: Fifty one shift workers took part in this study. They were working in a rapidly rotating system in which they worked for 3 days in one shift with one day off between each shift. Based on a sleep diary, sleep latency (SL), sleep period time (SPT), and number of wake after sleep onset (NWASO) were estimated and compared among the three shifts. In assessing sleepiness, Epworth sleepiness scale (ESS) and visual analogue scale (VAS) were used. To evaluate mood states among the three shifts, profile of mood states (POMS) was administered. Heart rate variability (HRV), and the level of adrenaline and noradrenaline were measured to assess autonomic activities. HRV included low frequency power (LF), high frequency power (HF), and LF/HF. Results: SPT was significantly lengthened during the evening shift and SL was shortened during the night shift. The workers showed a drop in alertness at wake-up during morning shift and a drop in alertness at work during night shift. During night shift the subjects complained of physical fatigue and cognitive decline. Comparison of HRV showed that parasympathetic activity was most prominent during the evening shift. Secretion of adrenaline and noradrenaline decreased during the evening shift, though statistically not significant. Conclusion: We found that the evening shift was most tolerable among the three shifts. It is recommended that morning light exposure be done during the morning shift and nocturnal light exposure during the night shift.

This study aimed to analyze and compare results from psychological relaxations by using profile of mood state (POMS) and Malondialdehyde (MDA) level as a scale of oxidative damage before and after walking in the forest and on the street. 29 participations (15 men and 14 women) walked in the forest and on the street for 30 minutes of each for two days. The participations filled a questionnaire for POMS and conducted an heart rate variability test, oxidative damage test (MDA as biological marker through a urine test) before and after walking. To compare the psychological states after walking in the two difference places, walking in the forest showed statistically more meaningful results in the section of tension, depression, anger, fatigue, confuse and total mood disturbance (p<0.01) than walking on the street. According to the MDA results, a concentration of MDA showed significant increase after walking on the street (p=0.014). On the contrary to this, a concentration of MDA tended to decrease after walking in the forest (p=0.076). The study showed that the psychological states were more stable and oxidative damages were more decreasing after walking in the forest than walking on the street. In the conclusion, MDA would be biological indicator for assessing the effect of alleviation on the oxidative stress after walking in the forest.

Objectives: The purpose of this study is to investigate the effects of the 37-hour sleep deprivation on visual discrimination using the Cybernetic Flicker Fusion Analyzer (FLIMK) and to see the correlation between this finding and various subjective scale scores. Methods: Twenty six subjects (20 men 6 women, $24.50{\pm}1.45$ years of age) participated in this study. Subjects remained awake for 37 hours under continuous surveillance. In the morning and evening of two study days, the FLIMK and the self-reporting scale of sleepiness, fatigue, anxiety and mood states were instituted. Results: In FLIMK, the flicker fusion threshold was significantly decreased after sleep deprivation (F=7.66, p=0.01). The number of trials (responses) before reaching fusion frequency threshold was significantly increased after sleep deprivation (F=13.16, p=0.001). The reduction of fusion frequency was correlated with the increase of sleepiness and fatigue (p<0.05), and the number of the trials was correlated with the scores of negative mood, anxiety, and fatigue (p<0.05). Conclusions: These results suggest that 37 hour total sleep deprivation cause the decrement in visual discrimination. The decrease of the fusion frequency after sleep deprivation was correlated with sleepiness and fatigue. Further study is needed to enlighten the biological mechanism of the decrement in visual function after sleep deprivation.

Purposes: Stress is known as a factor inducing various diseases in the human body. The purpose was to conduct a study on the stress change of 62 subjects who performed the newly developed "Holistic Healing(HH)Program" through the Happy Healing Group Program. Methods: Six sessions of the HH program were performed once a week (90 minutes) at the Happy Healing Meeting, and were surveyed activities of each session in detail. The HH program was developed to be applied to the general public, and it was composed of three detailed introduction-development-finish phases for each session. Results: After performing the Happiness Healing Meeting with the HH program the stress factor significantly decreased to 26.371 points in the post-test average value than the pre-test average value (p<.000). Psychological and social stress was reduced considerably to 9.096 points in post-test than in the pre-test measurement. Stress-coping method was significantly higher in the post-test with 201.661 points compared to the pre-test. Mood state was 69.451 points in the pre-test and 123.983 points in the post-test, showing a significant difference (p<.000). Conclusions: In the subjects who have been applied the holistic therapy program to the happiness healing small group, was significantly decreased general or psychosocial stress, and the stress-coping style and mood state change tended to increase. When evaluating this result, the SERIP Holistic Healing Program has been determined to be one of the very new holistic and beneficial natural healing therapies for the happiness healing small group.

Purpose: This exploratory study was to identify the use of complementary and alternative medicine(CAM) in women with breast cancer and to analyze which factor influence CAM use. Methods: 114 patients with breast cancer were identified and approached. The instrument used to gather data were the common types, main reasons and effects as well as stress, mood states and fatigue. Results: 42.7% of all participants reported the use of CAM. The most common types of CAM used were Phellinus linteus, elm tree, and vitamin C. The main reasons for CAM use were to boost the immune system and to prevent recurrence. Prayer, massage, Shitake mushroom, and Ganoderma lucidum were, identified as being more effective than others. 93.6% of the respondents informed their physicians of their use of CAM. Logistic regression analysis determined that stress, mood states, and duration after diagnosis were factors significantly associated with CAM use. Conclusion: CAM use is increasing among patients with breast cancer. Health care professionals are in the main position to identify what treatments patients are using and implement CAM therapies that can be helpful to relieve patient symptoms related to treatment and psychological distress.
