Objectives : School refusal is usually considered as individual's behavioral problem. These days. however. the adolescents' school refusal needs some kind of medical approaches because it is related to mental disorder of the adolescents. Due to too much pressure and stress from the competition between classmates and from good performance in school. the number of adolescents who refuse to go to school is increasing. Despite this circumstance. school refusal is neither regarded as a single independent disorder nor endorsed as an officially classified disease. which makes difficult to conduct research on this issue and to establish standardized treatment for it. In addition. there is a lack of research on this topic. especially in oriental medicine. so there is no a case report or study on school refusal. This study is trying to comment on school refusal from the perspective of oriental medicine. Methods : We tried to examine the effect of oriental medicine treatment for school refusal with four adolescent cases. The patients commonly have at least more than one mental disorder (including depression disorder. anxiety disorder. and anorexia nervosa). have some problem with the relationship with their family. in particular with mother. do not have father or not be loved by their father. and have irregular eating habits. Thus. we diagnosed them as qi transforming into fire (氣鬱化矢) spleen-stomach deficiency cold (脾胃虛寒) and heart blood deficiency (心血虛) due to stress from the family issues and unhealthy eating habits. The patients received supportive therapy. family therapy. etc among many oriental mental treatments and their progress had been observed through hospitalization and outpatient treatment. Results : All four cases were reported positive progress on their symptoms and started coming back to school. We also examined whether they were well fitting into the school while they received outpatient treatment. and the results show that all four patients continue to settle down in normal school life. Conclusions : This study closely reviewed the mental disorder of school refusal cases and showed that the Oriental medical treatment was effective in helping the patients come back to school. More future research is required to better treatment for school refusal cases in oriental medicine.

Advances in medical procedures and utilization of medication have resulted in expanding aged population, which leads to increased aged patients with salivary hypofunction and its associated symptoms in dental clinic. The purpose of this study was to investigate clinical characteristics of patients with dry mouth and its correlation with their salivary flow rate. Forty dry mouth patients (7 males, 33 females, mean age 42.0 years) whose flow rate of unstimulated whole saliva was less than 0.15 ml/min were included and their gender- and age-matched controls (7 males, 33 females, mean age 42.9 years) who did not report any complaints, suggestive of salivary gland dysfunction and had the flow rate of greater than 0.20 ml/min were included for comparison. The salivary flow rate was measured in both unstimulated and stimulated conditions. Dry mouth-related clinical information including history, dry mouth associated symptoms, exacerbating and relieving factors, drugs, systemic diseases, and family history was investigated using questionnaires. The differences in distribution of patients and control subjects to each question and their relation to the salivary flow rate were analyzed and we came to following conclusions. 1. There were statistically significant differences in the distribution of patients and controls to the following questions: the period and frequency of suffering from dry mouth; severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods, severity of discomfort in usual life due to dry feeling; self-assessment of residual salivary volume; taking medications. 2. The patients had more stress-related medical histories including indigestion, insomnia, and gastritis compared with controls. The patients took many kinds of medications to control their systemic diseases. 3. There were statistically significant differences in the salivary flow rate between different groups of patients to following questions: severity of dry feeling during a meal; severity of discomfort during swallowing; necessity of sipping liquids during swallowing dry foods. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one. 4. The salivary flow rate of patients taking medications was significantly less than that of patients who did not take medications. The difference was more significant in the case of stimulated salivary flow rate rather than unstimulated one.

Objectives The eye movement (EM) has been reported to play a role in enhancing the retrieval of episodic memories and reducing effects of fearful episodes in the past and worries for the futures. However, it is still unclear in the mechanism of EM in normal subjects. We examined the horizontal eye movement (HEM) effect using an aiding apparatus on mental health indices including negative and positive psychological factors, and psychophysiological measures such as heart rate variability and quantitative electroencepaholography (qEEG) in healthy subjects. Methods Twenty eight healthy subjects were recruited and randomly allocated into two groups : active HEM group and control group. The active HEM group conducted the HEM training with usual stress management audio-intervention using the apparatus inducing eye movement once a day for 14 days. The control group also conducted the same training once a day for 14 days, however, the saccadic eye movement was not included in this training. Psychological measurements, neurocognitive function tests, heart rate variability measurement and qEEG were conducted before and after the training in both groups. Results In the active HEM group, sleep status using Sleep Quality Scale (SQS) positive factors significantly increased after the training. By contrast, scores on the negative items of Psychological Well-Being Scale (PWBS), and negative items of the Life Orientation Test-Revised (LOT-R) were significantly decreased after the training. The percentage of delta amplitude (1-3 Hz) in qEEG significantly decreased after the HEM training. The percentage of alpha amplitude (8-12 Hz) significantly increased after HEM training. The change of delta amplitude in the active HEM group was positively correlated with the change of sleep satisfaction of Visual Analogue Scale (VAS), and the change of alpha amplitude was negatively correlated with depression of VAS, anxiety of VAS and Beck Anxiety Inventory (BAI). Conclusions The HEM training improved sleep quality and well-being, and sense of optimism. The HEM training also increased alpha amplitude and decreased delta amplitude in qEEG. The qEEG changes were well correlated with subjective improvement of mental health indices in healthy subjects. These results suggest some evidences that HEM training using the apparatus that induces EM would be helpful in improving subjective mental health in healthy subjects. Further study with larger samples size would be needed.

Purpose: The purpose of the study was to identify the attributes of self-help groups, their antecedents and consequences relating to self-help groups. Methods: We used the Walker and Avant (2010) method using the key word "self-help groups" the Korea Education and Research Information Service (www.riss4u.net), Pubmed, CINAHL and ProQuest for articles on this topic published between January 2000 and March 2013 were searched. Ultimately, 64 domestic and 21 foreign papers were selected for in-depth analysis. Results: The attributes of self-help groups are as follows: 1) members share common experiences and are supportive of each other; 2) members set goals for individual change; 3) groups are self-monitoring; 4) groups learn problem-solving processes through voluntary and active participation; and 5) groups are small and meet regularly. The antecedents of self-help groups are as follows: 1) an intervention by an expert; 2) a diagnosis of their illness; 3) motivation to change individuals' state; and 4) educational desire. The consequences of self-help groups are the relief of symptoms, the improvement of physiological parameters and quality of life, the decrease in depression, stress, and anxiety, the improvement of illness-related knowledge and self-help activity, and a change in beliefs. Conclusion: Self-help groups can be used as an intervention strategy to help people with chronic illness manage their own problems.

As a family respond to any stressful situation as a whole system, cancer diagnosis of a child, as a serious life event, could be emotional shock to destroy homeostasis of the family system. A family has a resilient capacity to adjust and adapt to stressful events. Previous studies have been focused on family stress and adaptation, but little attention has been given to family value as one of resilient factors. The data for model testing were collected from July 18, 2000 to August 30, 2000 and the analysis included 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, cluster analysis, factor analysis, and LISREL. The study findings are as follows. 1) Monthly income (γ=-0.28, t=-5.81) was the most important factor to explain family strain along with family support (γ=-0.11, t=-2.43), severity of children's illness (γ=0.26, t=5.22), and family stressor (γ=0.22, t=4.62). All of these factors together explained 40％ of variance in family strain. 2) Among general family value, the relationship with the parents (γ=0.28, t=4.89) and relationship with the children (γ=0.20, t=3.60) showed positive effects to family value for cancer children, while relationship with the spouse (γ=-0.19, t=-3.22) and the age of the cancer children (γ=-0.11, t=-2.21) showed negative effects. These predictors together explained 22％ of variance in family value for cancer children. 3) Family hardiness was explained mostly by family strain (γ=-0.53, t=-8.65) along with direct negative effects of family persistency and indirect negative effects of severity of children's illness, family stressor, relationship with the spouse, and the children's age. Family value for cancer children was the most important predictor with positive effect (γ=0.44, t=6.76) along with indirect effects of monthly income, relationship with the parents, relationship with the children, support from family and significant others, and confidence with the health professionals. 51％ of variance in family hardiness was explained by all of these predictors. 4) The most important predictor for family adaptation was family stressor (γ=-0.50, t=-6.85) with direct and indirect negative effects along with the severity of children's illness (γ=-0.27, t=-5.21). However, family value for cancer children showed compromised total effect (γ=-0.13, t=-1.99) with negative direct effects (γ=-0.28, t=-3.43) and positive indirect effects (γ=0.14, t=3.01). Similarly, confidence with the health professionals also showed compromised total effect (γ=0.09, t=1.99) with positive direct effects and negative indirect effects. Family hardiness showed the biggest positive direct effects while other factors such as monthly income, family stressor, family persistence, support of family and significant others, relationship with the parents, relationship with the children, and relationship with the spouse, and children's age showed indirect effects only. 39％ of variance in family adaptation was explained by all of these predictors.

The immune system acts to protect the host from infectious agents that exist in the environment and from other noxious insults. The immune system has two functional divisions: the innate and the acquired. Both components involve various factors such as cytokines. A number of methodologies exist to assess aspects of immune function. There are large inter-individual variations in many immune functions even among the healthy. Genetics, age, gender, smoking habits, habitual levels of exercise, alcohol consumption, diet, stage in the female menstrual cycle, stress, history of infections and vaccinations, and early life experiences are likely to be important contributors to the observed variation. While it is clear that individuals with immune responses significantly below 'normal' are more susceptible to infectious agents and exhibit increased infectious morbidity and mortality, it is not clear how the variation in immune function among healthy individuals relates to variation in susceptibility to infection. Oriental medicine is an important factor contributing to immune competence. The author investigated the immune enhancement effects of Bojungikkitanggami-bang (BITB). The forced swimming test (FST) has been used as a screening model for new immune enhancement agents. In the present study, the author investigated the effects of BITB on FST and blood biochemical parameters related to fatigue, glucose (Glc); blood urea nitrogen (BUN); lactate dehydrogenase (LDH); creatinine; and total protein (TP). The author found that BITB (1 g/kg) significantly reduced the immobility time in the FST compared to the control. In addition, the contents of Glc, LDH, BUN, TP in the blood serum were increased in BITB (1g/kg)-fed group. Also, the author investigated the effects of BITB on the production of cytokines in human T-cell line, MOLT-4 cells. BITB (1 mg/ml) significantly increased the interferon (IFN)-vproduction compared with media control (about 2.2-fold for IFN-γ) at 24 h. However, BITB has not affect the production of IL-2 and IL-4. In addition, BITB increased the protein expression level of IFN-γ in MOLT-4 cells. Thus, BITB may have therapeutic value in generating or enhancing immune function in a clinical setting.

KIF5는 2분자의 kinesin heavy chain (KHC)과 2분자의 kinesin light cham (KLC)으로 구성되며 미세소관과 직접 결합한다. KIF5는 여러가지 세포 내 소기관을 이동시키나 KIF5가 이동시키는 운반체가 어떻게 특이적으로 결합하는지는 아직 밝혀지지 못하였다. 본 연구에서 효모 two-hybrid system을 사용하여 KLC1의 tetratricopeptide repeats (TRP) 부위와 결합하는 세포 내의 단백질을 분리하였다. 결과 KLC1와 특이적으로 결합하는JNK/stress-activated protein kinase-associated protein 1 (JSAP1/JIP3)을 분리하였다. 이러한 결합은 KLC1의 TRP1, 2 영역과 JSAP1의 leucine zipper 영역이 결합에 관여하며, 또한 효모 two-hybrid assay에서 JSAP1은 KLC2와 결합하지만 신경세포에서 발현하는 KIF5A, KIF5C 그리고 모든 세포에서 발현하는 KIF5B와는 결합하지 않았다. 단백질간의 결합을 pull-down assay로 확인한 결과 KLC1은 glutathione S-transferase (GST)와는 결합하지 않으나 GST결한 JSAP1과는 결합하였다. 또한 생쥐의 뇌 파쇄 액으로부터 JSAP1 항체로 면역침강을 행한 결과 KLC1은 JSAP1과 같이 침강하였다. 이러한 결과들은 KLC1은 JSAP1과 결합하며, JSAP1은 KLC1의 수용체로세포 내 KIF5의 수송의 매개 단백질로 작용함을 시사한다.

This study was to examine single or combined in vitro effects of environmental endocrine disruptors on boar sperm characteristics, oxidative stress damage in sperm and development of porcine IVF embryos. Addition of various concentration of NP (10, 20, $30{\mu}M$), DBP (10, 50, $100{\mu}M$) and BPA (1, 5 or $10{\mu}g/ml$) on boar sperm characteristics such as percentages of sperm motility, viability, membrane integrity and mitochondrial activity were dose-dependently decreased within 3, 6 or 9 hr incubation period (p<0.05). The overall detrimental effects increased with incubation time increasement. NP, DBP and BPA showed the detrimental effects on sperm membrane and mitochondria of energy production organelles affecting cell viability with the dependancy of dose and incubation time. In combination effects, NP ($10{\mu}M$) + DBP ($10{\mu}M$) significantly decreased boar general sperm characteristics for 3 or 6 hr incubation period compared with control (p<0.05). When both of NP and DBP concentrations (NP; $30{\mu}M$, DBP; $100{\mu}M$) increase, the detrimental effects on sperm characteristics were larger than those of low concentration combination (p<0.05). The inhibitory effects of NP ($30{\mu}M$) + BPA ($10{\mu}g/ml$) on sperm characteristics were larger than those of NP ($10{\mu}M$) + BPA ($1{\mu}g/ml$) (p<0.05). DBP ($100{\mu}M$) + BPA ($10{\mu}g/ml$) decreased sperm characteristics compared with the low concentration combination (DBP $10{\mu}M$ + BPA $1{\mu}g/ml$, p<0.05). This result indicates the detrimental effects of both chemicals on sperm characteristics were dose dependent. Addition of NP ($30{\mu}M$) + DBP ($100{\mu}M$), NP ($30{\mu}M$) + BPA ($10{\mu}g/ml$), DBP ($10{\mu}M$) + BPA ($1{\mu}g/ml$) or DBP ($100{\mu}M$) + BPA ($10{\mu}g/ml$) significantly increased lipid peroxidation for 3 or 6 hr incubation period (p<0.05) compared with no addition control. NP (${\geq}20{\mu}M$) decreased the percentages of IVF embryo development from morulae and blastocyst stages (p<0.05) and its detrimental effects were dose-dependant. BPA 0, 1, 5 or $10{\mu}g/ml$ decreased significantly and dose-dependently the percentage of morulae plus and blastocysts (p<0.05). Combinations of DBP ($100{\mu}M$) plus NP ($30{\mu}M$) and DBP ($100{\mu}M$) plus BPA ($10{\mu}g/ml$) did not affect on morulae and blastocyst development, but NP ($30{\mu}M$) plus BPA ($10{\mu}g/ml$) has significant detrimental effect on embryo development at these stages (p<0.05). These overall results indicate that the partial detrimental effects on boar sperm characteristics and embryo development by NP, DBP, BPA or the combination of these chemicals might be due to the increasement of lipid peroxidation and free radical formation in the cell and there were no specific interaction effects on boar sperm and embryo degeneration among the combined treatments.
