We compared the degrees of stress response of 12 domestic purebred chicken strains that have been bred at National Institute of Animal Science, RDA, Korea since 1980. As a physiological marker of stress response, the expression levels of heat shock protein (HSP)-70, HSP-$90{\alpha}$, HSP-$90{\beta}$, hydroxyl-3-methyl-glutaryl coenzyme A reductase (HMGCR) genes and telomere length were measured by quantitative real-time polymerase chain reaction using the lymphocytes of 1,101 chickens. There was significant difference in HSP-70, HSP-$90{\alpha}$, HMGCR expression and telomere length among the strains. There was also significant difference in HSP-$90{\alpha}$, HSP-$90{\beta}$, and HMGCR expression between male and female chickens. Different age groups of chicken exhibited different expression levels of HSP-70, HSP-$90{\alpha}$ and telomere length. The results of the HSPs expression level suggested that, the strains of R, L and Y were highly resistant to stress, whereas the strains of S, O and W were susceptible to stress. Although the statistical differences in some of HSPs gene expression existed between genders, the HSP expression results varied in different strains that some opposed to the others, and there might be interaction between strains and genders, which conclude that there was no difference in stress response between male and female chickens. Moreover, despite of significant difference in some of HSPs expression level, it was considered that there was no difference in stress response between ages due to the inconsistent trends among HSP markers.

Objectives: This study was performed to examine the characteristic cardiovascular response patterns associated with the imagination and discussion of anger-provoked events in patients with hwa-byung. Methods: Forty-three female patients with hwa-byung were evaluated with the Korean version of the State-Trait Anger Expression Inventory, the State-Trait Anxiety Inventory, Hamilton Rating Scale for Anxiety, Beck Depression Inventory, and Hamilton Rating Scale for Depression just before the task. Subjective Units of Distress (SUDS) and Vividness of the event (VIVID) during the imagination and discussion of the event were evaluated immediately after tasks. Blood pressure (BP) and heart rate (HR) during baseline, rest, and tasks were also evaluated. Results: Both startle and recovery responses of BP, startle response of HR, SUDS, and VIVID in discussion task were significantly larger than in the imagination task. Conclusion: Results suggest that it is undesirable for the patients to excessively and repeatedly recall and talk about the anger events.

The purpose of this study was to explore linkages between stress and a range of individual difference factors on children's memory for a potentially stressful event. Children (N=63) aged from 4 to 10 years, who undergone a minor dental operative procedure were evaluated. Overall, the results of this study replicated and extended previous findings of the related literature, providing some further evidence for a negative relation between stress and children's recall. More considerable variation in individual difference variables, in particular, children 's stress coping strategies, quality of previous experiences, amount of the advanced parental preparation were existed among the children, influencing the relation between the level of stress and children's remembering of a stressful event. Future inquiries for understanding theoretical, clinical, and forensic issues in children's remembering of a stressful event were discussed.

This study compared the production and physiological characteristics of male and female Korean native commercial chickens. We investigated the growth performance, vitality, and stress response of 479 male and 608 female chickens from 1 d to 12 weeks of age. The body weight, feed consumption and feed conversion ratio were measured as growth performance. The survival rate, amount of telomeric DNA, DNA damage rate, heterophil-lymphocyte ratio (H/L ratio), and heat shock protein (HSP)-70, HSP-90α, and HSP-90β gene expression levels were analyzed as indicators of vitality and stress response. Body weight was significantly higher in male chickens than in female chickens after 2 weeks of age (P<0.01). Feed intake was higher in male chickens than in female chickens, whereas the feed conversion ratio showed the opposite trend. The survival rate was significantly higher in female chickens than in male chickens (82.8% vs. 73.8%, P<0.05). Stress response analysis revealed no differences between male and female chickens in terms of telomeric DNA content, DNA damage rate, H/L ratio, and HSP gene expression levels. Taken together, it was concluded that there was a significant difference in the growth performance and survival rate between male and female Korean native commercial chickens, whereas there was no difference in the degree of stress response between them. Therefore, in terms of the productivity of Korean native commercial chickens, it is judged that separate-sex rearing is much more advantageous than mixed rearing, regardless of the physiological characteristics of males and females.

With Single Comb White Leghorn (WL) and Korean Native Chicken (KNC) breeds, we compared the stress response with chicken breeds that were subjected to a high stocking density. Stress response was analyzed by the quantity of telomeric DNA, the rate of DNA damage and the expression levels of heat shock proteins (HSPs) and hydroxyl-3-methyl-glutaryl coenzyme A reductase (HMGCR) genes on tissues and blood. The telomere length and telomere shortening rates were analyzed by quantitative fluorescence in situ hybridization on the nuclei of lymphocytes and tissues. The DNA damage rate of lymphocytes was quantified by the comet assay. The expression levels of HSP70, HSP90-${\alpha}$, HSP90-${\beta}$ and HMGCR genes were measured by quantitative real-time polymerase chain reaction in lymphocytes. There was no significant difference between KNC and WL in body weight, weight gain, telomere shortening rate and DNA damage rate. However, the growth rate significantly decreased in chickens raised under high stocking density conditions, as compared to the control group. The telomere-shortening rate, DNA damage and HSPs expression of the lymphocytes were significantly higher in the high stocking density group than the control. The stress condition and breeds had a significant effect on the expressions of HSP70, HSP90-${\alpha}$ and HSP90-${\beta}$ in lymphocytes, except HMGCR. The stress response of WL was higher than that of KNC, as analyzed to the expression of HSP70 and HSP90-${\alpha}$. Therefore, we concluded that the chickens which were exposed to a high stocking density had increased the individual physiological stress response regardless of breeds, and White Leghorns are more susceptible to stress condition than Korean Native Chickens.

Objectives : The purpose of this study was to investigate the various aspects of stress in patients with chronic prostatitis. Methods : Thirty two chronic prostatitis patients meeting the criteria of NIH-category III were compared with sixty four controls. Data pertaining to the source of, response to, and coping with stress, as well as chronic prostatitis symptom index were collected using a self-report questionnaire. The questionnaire consisted of a Global Assessment of Recent Stress(GARS), Stress Response Inventory(SRI), Ways of Coping Checklist(WCC), in addition to the NIH-CPSI. Results : From the results of GARS subscales, the scores of changes in relationship, sickness or injury and financial were significantly higher in patients with chronic prostatitis than normal controls. Chronic prostatitis patients had greater amplification of somatization, depression and anger in SRI and significantly lower score in ways of coping checklist compared with controls. In the NIH-CPSI of chronic prostatitis patients, the degree of symptom played a role in depression as stress response item and significant negative correlationship between the symptom point and problem focused, seeking social support coping strategy was observed. Conclusion : These results show that patients with chronic prostatitis have greater stress, higher stress response and insufficient coping strategy. Therefore, these efforts should be considered that enhancing healthier coping strategy and evaluation and management of stress experienced by chronic protatitis patients

This study examined the stress reaction, resilience levels, and the effects of the stress reaction on the resilience among dental hygiene students. From July 11, 2016 to July 29, 2016, questionnaires were collected from 274 dental hygiene students in several areas. The collected data were analyzed by descriptive statistics, t-test, One-way ANOVA, Pearson correlation coefficient, and multiple regression using SPSS Statistics ver.21.0. The stress reaction level of dental hygiene students was found to be 2.59 out of 5 points and the resilience level was 4.47 out of 7 points. The stress reaction and resilience showed a significant negative correlation in Fatigue, Tension, Frustration, Anger, Depression, Aggression(p>0.001), and stomatization(p>0.05). In other words, the lower the resilience, the higher the stress reaction.The factors of stress reaction influencing the resilience were depression and somatization, which explained 25.6%(R2=0.256). Therefore, to enhance the resilience of dental hygiene students, it is important to investigation the stress reaction and there should be more concern with students who have higher depression and stomatization. In addition, efforts to control the stress reaction are needed.

본 연구는 쾌하고 안정의 감성을 유발하는 향과 상대적으로 쾌도가 작고 각성의 감성을 유발하는 향이 스트레스 자극 후에 안정 상태로의 회복에 미치는 영향을 관찰하고자 하였다. 사용된 향은 100%의 Rose oil bulgarian, Lemon oil misitano, Jasmin abs., Lavender oil france (KIMEX co. Ltd)의 네 가지이고 자율신경계의 반응은 심전도, 피부저항의 생리신호로 측정하였다. 스트레스의 유발은 단계적으로 난이도를 증가시키면서 덧셈의 연산 결과가 옳은지 틀린지를 검증하게 하였다. 실험과정은 처음의 안정 상태를 3분간 측정하였고, 2분의 계산 부하가 주어졌고 다시 3분간의 회복 상태를 측정하였다. 3분간의 회복 과정 측정 시 향을 제시하지 않은 상태를 통제 집단으로 하여 각각의 향을 제시했을 때의 상태와 비교하였다. 주관적 평가에서 상대적으로 레몬과 라벤더 향은 긍정과 이완 감성을, 자스민과 장미는 부정과 긴장 감성을 유발하는 향이라고 피험자들은 대답하였고 이것은 생리신호의 분석결과 스트레스 자극 유발 후 안정상태로의 회복이 향을 제시하지 않은 상태와 비교해서 레몬과 라벤더 향을 제시했을 때 빨라지고, 장미향을 제시했을 때 느려진다는 사실과 어느 정도 일치한다. 그러므로 비록 예비 실험이기는 하지만 본 연구에서는 스트레스에 의해 유발된 교감신경계 활성화의 회복을 촉진시키거나 또는 더디게 하는 향의 심리적 효과를 자율신경계의 반응으로서 검증할 수 있었다.
