This study was conducted to find out physical changes in the blood pressure and saliva cortisol of patients with high blood pressure and diabetes after participating in agro-healing activities. The saliva cortisol and blood pressure of 14 males and females aged 49.79±10.48 on average were measured after participating in agro-healing activities. The saliva collection system was used, and their satisfaction level for the program was also surveyed. Changes in the values before and after participating in the agro-healing activities were compared and analyzed. The cortisol concentration, a stress hormone, was reduced from 6.76nmol/L before the program to 4.86nmol/L after the program, down by 1.9nmol/L, which was a statistically significant difference (z=-3.170, p<.01). In addition, the cortisol concentration was gradually reduced through the entire program from Session 1 to Session 7. Changes in the blood pressure of subjects before and after participating in agro-healing activities were examined, and the total systolic and diastolic blood pressure continuously decreased after participating in agro-healing activities through the entire program from Session 1 to Session 7. Their systolic blood pressure was reduced statistically significantly (z=-1.947, p<.05). Also, participants' satisfaction was analyzed and it was found that more than 95% of participants answered 'satisfied' and 'very satisfied' with agro-healing activities. Therefore, these results indicate that agro-healing activities performed in the healing-farm had a positive impact on the cortisol concentration and blood pressure of patients with chronic diseases such as diabetes and high blood pressure. In addition, their high satisfaction for this program seemed to improve the psychological and physiological conditions of subjects.
The present study was conducted to evaluate the effects of fermented soybean meal (FSBM) on the level of cortisol hormone and immune-related serum proteins in weaned calves after experimentally induced lipopolysaccharide (LPS) challenge. Holstein neonatal calves (n = 21; 8 males and 13 females, BW = $42.2{\pm}6.15$ kg) were randomly allocated to one of two dietary treatments: SBM (control calf starter having soybean meal (SBM) as a main protein source) and FSBM (substitute SBM in control diet with FSBM) groups. All calves were fed milk replacer using an automatic milk-feeder according to step-down milking method and weaned at 7 weeks old. Experimental diets were given to calves ad libitum throughout the experimental period. For LPS challenge, all calves except negative control animals given phosphate buffered saline (PBS), were injected subcutaneously with Salmonella typhimurium LPS on day 7 (D7) after weaning (D0). No significant difference in growth performance and milk intake was observed between SBM and FSBM calves. Feeding FSBM diet resulted in significantly (p<0.05) higher LPS-specific IgG at D12 and D19 and LPS-specific IgA at D19 in peripheral blood. Calves fed with FSBM diet also had significantly (p<0.05) higher concentration of serum haptoglobin (Hp) at D8. Overall concentration of cortisol in FSBM group was considerably lower than that of SBM group. Results from current study indicate that FSBM may provide beneficial effects in alleviating weaning stress and enhance immune status of weaned calves.
The precise measurement of human emotion is of pivotal importance in the field of emotion science. Based on the perspective of psychoneuroimmunoendocrinology, human emotion is now considered to be measurable by body fluid. The biological molecule cortisol, which is known for the stress hormone, has been widely investigated to help researchers to estimate the stress loaded on human body. Until now, several measurement techniques such as High Performance Liquid Chromatography (HPLC), fluorometric assay, and reverse phase chromatography have been developed. However, since these measurements are expensive, take relatively long time for an operation, and they are not portable, they are not appropriate for POCT (point of care testing). In this paper we demonstrate the performance of a miniaturized-microwave resonant device in the measurement of cortisol. Our method has many advantages in that it requires a small volume of sample, has fast response time, is easy to operate and needs no labeling process. Besides, it will shed a light on the measurement techniques for emotion science.
We tried to determine the optimum salinity for a cultured of olive flounder (Paralichthys olivaceus) by investigating after exposing the fish at different salinity (10, 15, 20 and 25 psu) for 24 and 48 hours compared with control group (fish before transfer to experimental tank). As a control groups, we compared an analyzed with other experimental groups using olive flounder in natural sea water. Hematological parameters including hematocrit (Ht) and hemoglobin (Hb), cortisol and glucose, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), $NH_3$, osmolality, total protein (TP), $Na^+$, $K^+$ and $Cl^-$ mostly exhibited significant changes at 10 and 15 psu groups compared with control groups for 24 and 48 hours exposed. Plasma SOD (superoxide dismutase) and CAT (catalase) activity also increased with experimental groups (10 and 15 psu) compared to the control groups. The expression of HSP70 mRNA was also higher at low-salinity (10 and 15 psu) than at control group. In particular, after 24 hours exposed, it expression to 15 psu groups showed a significant difference compared to the control group. However, after 48 hours exposed, it expression was higher in the 10 psu groups than the control. It is assumed that the changes in the hematological responses and hormone, homeostasis and metabolism were resulted in to protect fish body from stress. Based on these results, we are expected that it will be used as basic data for the culture of olive flounder prepared for low salinity.

Background: Depression is one of the most commonly diagnosed neuropsychiatric diseases, but the underlying mechanism and medicine are not well-known. Although Panax ginseng has been reported to exert protective effects in various neurological studies, little information is available regarding its antidepressant effects. Methods: Here, we examined the antidepressant effect and underlying mechanism of P. ginseng extract (PGE) in a chronic restraint stress (CRS)-induced depression model in mice. Results: Oral administration of PGE for 14 d decreased immobility (depression-like behaviors) time in forced swim and tail suspended tests after CRS induction, which corresponded with attenuation of the levels of serum adrenocorticotropic hormone and corticosterone, as well as attenuated c-Fos expression in the amygdala. PGE enhanced messenger RNA expression level of brain-derived neurotrophic factor but ameliorated microglial activation and neuroinflammation (the level of messenger RNA and protein expression of cyclooxygenase-2 and inducible nitric oxide synthase) in the amygdala of mice after CRS induction. Interestingly, 14-d treatment with celecoxib, a selective cyclooxygenase-2 inhibitor, and $N_{\omega}$-nitro-L-arginine methyl ester hydrochloride, a selective inducible nitric oxide synthase inhibitor, attenuated depression-like behaviors after CRS induction. Additionally, PGE inhibited the upregulation of the nuclear factor erythroid 2 related factor 2 and heme oxygenase-1 pathways. Conclusion: Taken together, our findings suggest that PGE exerts antidepressant-like effect of CRS-induced depression by antineuroinflammatory and antioxidant (nuclear factor erythroid 2 related factor 2/heme oxygenase-1 activation) activities by inhibiting the hypothalamo-pituitary-adrenal axis mechanism. Further studies are needed to evaluate the potential of components of P. ginseng as an alternative treatment of depression, including clinical trial evaluation.

The purpose of this study was to investigate changes in salivary cortisol content in 35 subjects before and after visiting Gotjawal Forest in Jeju. Cortisol raw samples were collected before and after visiting Gotjawal Forest and were analyzed by salivary cortisol enzyme immunoassay. The period of the study was from May 1, 2017 to June 30, 2017. There was no significant difference in cortisol content between the control and experimental groups before the visit, but the value of the experimental group significantly decreased afterwards. The mean value of cortisol in male subjects was lower than that of the control group. In the case of women, the value of the experimental group was lower than that of the control group. The post-visit cortisol content of the experimental group was significantly lower than that of the control group. In the post-visit analyses according to gender and group, there were significant differences between genders, groups, and combined effects of gender and group. This study provides basic data to prove the effects of forest bathing.

Brassinosteroid (BR), a plant steroid hormone, plays a critical role in the growth and developmental processes through its canonical signaling and crosstalk with various internal and external signaling pathways. Recent studies have revealed the essential interplay mechanisms between BR and ABA during seed germination and early seedling establishment. However, molecular mechanisms for this important signaling crosstalk are largely unknown. To understand the crosstalk between BR-mediated signaling pathways and ABA functions during early seedling development, we carried out a comparative genome-wide transcriptome analysis with an Agilent Arabidopsis $4{\times}44K$ oligo chip. We selected and compared the expression patterns of ABA response genes in ABA-insensitive bes1-D mutant with wild type seedlings on which ABA was exogenously applied. As a result, we identified 2,353 significant differentially expressed genes (DEGs) in ABA-treated bes1-D and wild type seedlings. GO enrichment analysis revealed that ABA signaling, response, and metabolism were critically down-regulated by BR-activated signaling pathways. In addition, the genome-wide transcriptome analysis data revealed that BR-regulated signaling pathways were tightly connected to diverse signal cues including abiotic/biotic stress, auxin, ROS etc. In this study, we newly identified the molecular mechanisms of BR-mediated repression of ABA signaling outputs. Also, our data suggest that interplay among diverse signaling pathways is critical for the adaptive response of the plant to various environmental factors.

The development of various electronic media such as the Internet and smart phones, each kinds of media informations has been accompanied by the fact that various types of media information are provided from one media, and on the other hand, various dysfunctions including smart phone addiction are also caused by a very large social problem. Especially, one of the biggest dysfunctions is the social crime problem such as sex crime caused by increased sexual desire according to watch the phonography, and even if it is not a social crime, watching the phonography has influenced bad mental and physical on human body. In this paper, we try to analyze what kind of change occurs in the voice in order to investigate what kind of bad influence it has on the human body after watching the phonography. In other words, the voice in the human body is the place where the human body signal is most expressed with the face. Therefore, the purpose of this study is to investigate the effects on the organs of the human body by comparing the change of voice before and after watching phonography. Experimental results showed that the stress hormone was increased by the inability to resolve sexual desire after watching the phonography, which resulted in an increase in the bandwidth of the 3rd formant frequency.
Despite the risk of high altitude disease (HAD), raising cattle at higher altitudes does have advantages such as beef quality due to minimal chance of infection and stress. The ideal situation is to determine the optimum altitude suitable for raising cattle while at the same time minimizing the risk of HAD. Therefore, in this study, we documented the health status of three groups of steers, raised at three different altitudes (200m, 400m and 800m) in Gangwon province, using routine hematological, biochemical and hormonal tests. The red blood cell counts and hemoglobin concentration were highest in the 800m group, and lowest in the 200m group, possibly due to hypoxia induced myeloid and erythroid stimulation. The mean concentration of AST, BUN and serum cortisol were lowest in the 800m. These findings suggest the stress factor will contribute the general health status of animal and indicate a difference in the Hanwoo groups raised at 800m compared to 200m, where the cattle raised at the higher altitude exhibit better health status compared to the lower altitude, possibly due to less stressful environment in the higher altitude.
Background: Postoperative fluid retention is a factor that causes delay in recovery and unexpected adverse events. It is important to prevent intraoperative fluid retention, which is putatively caused by intraoperative release of stress hormones, such as ADH (anti-diuretic hormone) or others. We hypothesized that intraoperative analgesia may prevent pathological fluid retention. We retrospectively explored the relationship between analgesics and in-out balance in surgical patients from anesthesia records. Methods: Anesthetic records of 80 patients who had undergone orthognathic surgery were checked in this study. Patients were anesthetized with either TIVA (propofol and remifentanil) or inhalational anesthesia (sevoflurane and remifentanil). During surgery, acetated Ringer's solution was infused for maintenance at a rate of 3-5 ml/kg/h at the discretion of the anesthetist. The perioperative parameters, including the amount of crystalloid and colloid infused, and the amount of urine and bleeding were checked. Furthermore, we checked the amount and administration rate of remifentanil during the surgical procedure. The correlation coefficient between the remifentanil dose and the in-out balance or the urinary output was analyzed using the Pearson correlation coefficient. The contributing factor to fluid retention, including urinary output, was statistically examined by means of multivariate logistic regression analysis. Results: A significant positive correlation was found between remifentanil dose and urinary output. Urinary output less than 0.04 ml/kg/min was suggested to cause positive fluid balance. Although in-out balance approaches zero balance with increase in remifentanil administration rate, no contributing factor for near-zero fluid balance was statistically picked up. The remifentanil administration rate was statistically picked up as the significant factor for higher urinary output (> 0.04 ml/kg/min) (OR, 2,644; 95% CI, 3.2-2.2 × 106) among perioperative parameters. Conclusions: In conclusion, remifentanil contributes in maintaining the urinary output during general anesthesia. Although further prospective study is needed to confirm this hypothesis, it was suggested that fluid retention could be avoided through suppressing intraoperative stress response by means of appropriate maintenance of remifentanil infusion rate.
