Objectives: This study aims to investigate the effects of voice disorders on changes in stress among people with damaged larynxes. To accomplish this, physiological changes and reductions in the stress of Sprague-Dawley rats whose larynx had been damaged were investigated after the laboratory animals were administered kudzu leaf extracts with sedative effects. Methods: In the experiment, a total of 24 rats were divided into four groups of six rats, including the normal group, control group, experimental group 1, and experimental group 2. After orally administering to the subjects a predetermined amount of the extract at a specific time (once per day over five weeks), changes in physiological functions, internal organ weight, cortisol, estrogen, and progesterone in the subjects were examined, and an immunological test was conducted on their brain tissues. Results: Statistical significance was seen in the experimental group as opposed to the control group and the results were similar to those of the normal group. Conclusions: In consideration of these results, it is deemed that there are severe effects on stress due to voice disorders and that the administration of kudzu leaf extracts results in improvement in stress.

This study tried to identify the job stress characteristics of female bank workers and the relationship between their stress and symptoms associated with musculoskeletal disorders(MSDs). The total number of 587 female bank tellers have been participated in this study. Specifically, questionnaire surveys regarding job stress and MSDs symptoms were conducted. On the basis of the results from the survey using Korean version of job stress questionnaire with 24 questions, stress scores associated with job requirement and job flexibility were relatively high. The job stress levels regarding job demand, organizational system, occupational climate at the work place were relatively high for the full time workers while the job stress levels regarding insufficient job control, job stability, interpersonal conflict, lack of reward were relatively high for the part time worker. The workers with longer total work years had relatively high job stress associated with interpersonal conflict, and organizational system while the workers with longer work years at the current job had relatively high job stress associated with occupational climate. Also, the workers with longer working hours a day had relatively high job stress associated with job demand, interpersonal conflict, organizational system, and occupational climate. According to the relationship identified in this study, symptoms at the neck, shoulder, hand, low back. leg were associated with the stress levels in terms of job flexibility, interpersonal conflict, job requirement, job stability. In conclusion, female bank workers are exposed to job stress due to their specific job characteristics and there has been certain relationships between their job stress and MSDs symptoms.

Bereavement is the state of loss resulting from death. Grief is the emotional response associated with loss, intense and acute sorrow resulting from loss. Complicated grief represent a pathological outcome involving social, physical, emotional, cognitive, spiritual morbidity. The common psychiatric disorders associated complicated grief or abnormal grief responses include clinical depression, anxiety disorders, alcohol abuse or other substance abuse, and dependence, psychotic disorders, and post-traumatic stress disorder (PTSD). Grief tasks involve a series of stage or phases following an important loss that gradually permit adjustment and recovery. Three phases of grief involve phase 1 (walking the edges), phase 2 (entering the depths), and phase 3 (reconnecting the world). For intervention to be effective they need to be individually tailored to abnormal grief reaction or unresolved grief reaction. Clear understandings of complicated grief, abnormal responses, factors increasing risk after bereavement will often enable us to prevent psychiatric disorders in bereaved patients.

Recently, Eye Movement Desensitization and Reprocessing (EMDR) was given the status of an approved form of psychotherapy for the treatment of post-traumatic stress disorder. However, its effectiveness in the treatment of other anxiety disorders such as phobia is yet to be determined given that controlled studies have provided mixed results. This report summarizes the case of a child with a specific phobia (i.e. nighttime fear) which was successfully treated with two sessions of EMDR. This result suggests the further and thorough evaluation of this technique for use in childhood phobic disorders.

In chronic temporomandibular disorders (TMDs), constituent tissues such as muscles are sensitive to pain and psychological stress, which negatively affect the quality of life. In addition, since chronic TMDs is often accompanied by diseases such as psychological disorders and other chronic pain disorders, the diagnosis of those diseases and patient referrals are mandatory. The management of chronic pain in TMDs requires a multidisciplinary and holistic approach. Pharmacological therapy using cyclobenzaprine, serotonin and norepinephrine reuptake inhibitors, tricyclic antidepressants, progressive relaxation, and psychological approaches using cognitive behavioral therapy such as shifting negative thoughts about pain are all valid treatment options.

Objective : Eye movement desensitization and reprocessing (EMDR) has been established as an effective treatment for patients with posttraumatic stress disorder (PTSD). However, the literature is unclear as to whether EMDR is effective in the treatment of other psychiatric disorders. The purpose of this study was to evaluate the potential use of EMDR in the treatment of psychiatric disorders other than PTSD by using a clinician's impression of patient response and a subjective symptom evaluation. Methods : Seventeen diagnostically heterogenous patients without PTSD underwent an average of 4.3 sessions of EMDR. Symptom severity was assessed by the Clinical Global Impression-Change Scale (CGIC), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Symptom Checklist-90- Revised (SCL-90-R) before and after EMDR. Those whose CGI-C scores were 'very much improved' and 'much improved' after EMDR were classified as 'responders.' The patients' before and after treatment scores of symptom severity and group differences were compared. Results : Twelve of the 17 participants (12/17, 71%) were classified as 'responders.' The patients' scores on all of the scales, with the exception of the trait anxiety scale and obsession-compulsion scale of the SCL- 90-R, significantly decreased after treatment. There was no difference in sociodemographic and clinical variables between the responders and non-responders. Conclusion : The results of our study suggest that EMDR can be a promising candidate for the treatment of patients with psychiatric disorders other than PTSD, and thus further controlled studies are needed to determine whether EMDR can be applied to various psychiatric populations.

Background: Microglial cells, major immune effector cells in the central nervous system, become activated in neurodegenerative disorders. Activated microglial cells produce proinflammatory mediators such as nitric oxide (NO), tumor necrosis factor-$\alpha$ and interleukin-$1{\beta}$(IL-$1{\beta}$). These proinflammatory mediators have been shown to be significantly increased in the neurodegenerative disorders such as Alzhimer's disease and Pakinson's disease. It was known that one of the neurodegeneration source is stress and it is important to elucidate mechanisms of the stress response for understanding the stress-related disorders and developing improved treatments. Because one of the neuropeptide which plays a main role in regulating the stress response is corticotropin-releasing hormone (CRH), we analyzed the regulation of NO release by CRH in BV2 murine microglial cell as macrophage in the brain. Methods: First, we tested the CRH receptor expression in the mRNA levels by RT-PCR. To test the regulation of NO release by CRH, cells were treated with CRH and then NO release was measured by Griess reagent assay. Results: Our study demonstrated that CRH receptor 1 was expressed in BV2 murine microglial cells and CRH treatment enhanced NO production. Furthermore, additive effects of lipopolysaccaride (LPS) and CRH were confirmed in NO production time dependantly. Conclusion: Taken together, these data indicated that CRH is an important mediator to regulate NO release on microglial cells in the brain during stress.

Acupuncture has been used for the treatment and prevention of stress-related disorders. In the present study, the effect of electroacupuncture on the behavioral and biochemical responses to restraint stress was evaluated in rats. Sprague-Dawley male rats underwent to immobilization stress for 21 days (6 hours/day). Electroacupuncture (2 Hz, 2 mA, and 10 minutes) was applied either to the acupuncture point HT7 (Shenmen) or the nonacupuncture point in the tail for the last 7 days. Rats were randomly divided into four groups: the normal group (n=10, without the restraint stress), the stress group (n=10, with restraint stress), the HT7 group (n=10, with restraint stress and electroacupuncture to HT7), and the NA group (n=10, with restraint stress and electroacupuncture to the nonacupuncture point). The anxiety-related behavior was tested using the elevated plus maze and the Vogel test on day 22. The expression of tyrosine hydroxylase in the locus coeruleus was measured by immunohistochemistry. R maze and the Vogecreased the response of the anxiety-related behavior. The number of tyrosine hydroxylase-immunoreactive cells were also increased. The HT7 group showed a significant decrease of anxiety-related behavioral response, compared to the stress group. The tyrosine hydroxylase-immunoreactive expression was also decreased in the HT7 group. These findings suggestthat electroacupuncture to HT7 might play a role in reducing the stress-related responses, which may be helpful for the treatment of stress-related disorders.
