Purpose: The purpose of this study was to evaluate the effects of self-foot reflexology on stress (perceived stress, urine cortisol level, and serum cortisol level), fatigue, skin temperature and immune response in female undergraduate students. Methods: The research design was a nonequivalent control group pretest-post test design. Participants were 60 university students: 30 in the experiment group and 30 in the control group. The period of this study was from April to June 2010. The program was performed for 1 hr a session, three times a week for 6 weeks. The data were analyzed using the SPSS/WIN 17.0 program. Results: The results showed that self-foot reflexology was effective in reducing perceived stress and fatigue, and raised skin temperature in female undergraduate students. But cortisol levels and immune response were not statistically significant different. Conclusion: The results of this study indicate that self-foot reflexology is an effective nursing intervention in reducing perceived stress and fatigue and, in improving skin temperature. Therefore, it is recommended that this be used in clinical practice as an effective nursing intervention for in female undergraduate students.

PURPOSE: This study examined the changes in the blood fatigue variables caused by isokinetic and isotonic exercise training. METHODS: Ten healthy adult males with at least one year of athletic experience participated. The participants performed the isokinetic circuit exercise program first, followed by an isotonic circuit exercise program. A two-hour break was allowed between the isokinetic circuit exercise program and the isotonic circuit exercise program. The circuit exercise program consisted of four items (Squat, Deadlift, Shoulder press, and Bench press). The blood samples were analyzed for the LDH, CPK, and Cortisol levels. RESULTS: The LDH level in the isokinetic group was significantly different from the isotonic group. In particular, the change in LDH level in the isokinetic group was 33.30% lower than that of the isotonic group. The serum CPK level of the isokinetic group showed a 10.03% lower decrease than the isotonic group, but the difference was not significant. The Cortisol level was relatively unchanged in the isotonic group, but it decreased in the isokinetic group. On the other hand, the Cortisol level did not show a significant difference between the two groups. CONCLUSION: The isokinetic group showed alleviation of the three indices, unlike the isotonic group. Further studies associated with the changes in blood fatigue variables through various exercise programs and exercise intensity will be needed.

연구배경 : 천식의 치료에 있어서 코티코스테로이드의 사용은 중요하며 스테로이드 사용으로 인한 부작용 때문에 장기치료시 흡입성 코티코스테로이드가 최근 천식의 치료에 1 차 치료약으로 널리 쓰이게 되었는데 이중 fluticasone propionate는 가장 강력한 항 염증성 흡입성 코티코스테로이드 제재로 알려져 있으며 지금까지의 연구보고들은 fluticasone propionate가 시상하부-뇌하수체 부신 축 기능에 미치는 영향이 적다고 보고하였으나 3개월 이상 장기간 사용하는 경우는 보고된 것이 미미하였다. 방 법 : 저자들은 본원 호흡기 내과로 내원하여 치료중인 천식환자들을 대상으로 본 연구에 동의한 23명의 기관지천식 환자를 대상으로 하였다. 그중 2명은 추적검사가 이루어지지 않아 제외시키고 나머지 21 명을 대상으로 하였다. 6개월 이상 fluticasone 흡입제를 사용 후 급속 ACTH 자극검사로 시상하부-뇌하수체-부신 축 기능에 대한 이상여부를 검사하였다. 결 과 : 전체 환자 21 명에서 혈중 기저 cortisol 수치는 $11.0{\pm}6.4\;{\mu}g/d{\ell}$(mean$\pm$SD)이었고 30분후 혈중치는 $20.0{\pm}7.7\;{\mu}g/d{\ell}$이었으며, 60분후 혈중치는 $23.0{\pm}6.3\;{\mu}g/d{\ell}$이었다. 검사를 시행한 21명의 환자 중 16명의 환자는 정상 반응을 나타내었으며 5명은 시상하부-뇌하수체-부신 축이 억제되는 소견을 보여주었다. 비정상 반응을 보인 5명의 혈중 기저 cortisol치는 $4.8{\pm}2.0\;{\mu}g/d{\ell}$(mean$\pm$SD)이었으며 30분 후의 cortisol치는 $12.2{\pm}2.8\;{\mu}g/d{\ell}$, 60분 후의 cortisol치는 $14.2{\pm}3.5\;{\mu}g/d{\ell}$이었다. 결 론 : 본 연구는 연구대상이 작아서 용량과 시상하부-뇌하수체-부신 축의 억제정도와의 관계를 정확히 증명할 수는 없었으나 6개월 이상 장기간 사용시 시상하부-뇌하수체-부신 축이 억제될 가능성이 있음을 보여주었다. 따라서 장기간의 치료를 요하는 대다수의 기관지 천식 환자에서 임상의들은 환자의 임상증상을 고려해서 흡입제 치료에 있어서 전체적인 투여량과 투약기간의 결정에 주의를 하여야 할 것으로 생각된다.

Objectives: Patients undergoing oral surgery exhibit high anxiety, which may elevate their cortisol levels and affect postoperative recovery. Overweight patients are often encountered in the dental clinic due to the increasing prevalence of overweight. We aimed to investigate the relationships between preoperatively assessed body mass index (BMI), serum cortisol and high-sensitivity C-reactive protein (hs-CRP) levels, and visual analog scale (VAS) scores and preoperative anxiety in patients undergoing mandibular third molar (MM3) extraction and to identify predictors of postoperative complications. Patients and Methods: We analyzed 43 patients (age, 20-42 years) undergoing MM3 extraction. At the first visit, patients completed the Modified Dental Anxiety Scale (MDAS) and Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaires. Their BMI and VAS scores were also calculated. The participants underwent blood tests 1 hour before MM3 extraction. On the first postoperative day, the participants' VAS scores and serum hs-CRP levels were reevaluated. Results: We found that BMI was significantly correlated with preoperative VAS scores. Further, BMI and preoperative hs-CRP levels were significantly correlated among women and patients undergoing extractions of fully impacted MM3s. No correlations were found between serum cortisol and other variables. The preoperative MDAS and VAS scores were significantly positively correlated, especially among patients undergoing extractions of fully impacted MM3s. Multiple linear regression showed that BMI and the eruption status of the MM3 were significant predictors of postoperative hsCRP levels and VAS scores, respectively. Conclusion: In MM3 removals, patients with higher BMI showed elevated hs-CRP and higher VAS scores before surgery. Patients with higher anxiety among those undergoing extractions of fully impacted MM3s showed higher preoperative VAS scores. The two main predictors of postoperative complications were BMI and MM3 eruption status.

연구배경 : 스테로이드제제는 기관지 천식 및 만성 폐쇄성 폐질환 환자치료에 매우 효과적으로 항염작용, 기관지내 과민반응 억제 및 기타 면역학적인 기전으로 작용한다. 그러나 부신피질 기능억제, 쿠싱 증후군, 골다공증 등의 전신적 부작용으로 인해 그 사용 범위가 제한되어 왔다. 1970년대 초반부터 고도의 국소적 작용을 갖는 흡입성 스테로이드제제가 천식 치료에 활발히 이용되고 있으나 이 약물 투여에 따른 기저 코티솔 농도에 미치는 영향에 대해서는 아직도 논란이 많다. 이에 저자들은 최근에 개발된 강력한 흡입성 스테로이드제제인 fluticasone propionate의 시상하부-뇌하수체-부 신축에 미치는 영향을 알아보고자 기관지천식과 만성 폐쇄성 폐질환 환자를 대상으로 하여, 단기간 투여용량에 따른 fluticasone propionate의 기저 코티솔 농도에 미치는 영향을 관찰하였다. 방 법 : 1993년 7월부터 1997 년 3월까지 전북대학교 병원 내과에 입원치료한 기관지 천식과 만성 폐쇄성 폐질환환자를 대상으로 하였다. 환자는 흡입성 fluticasone propionate 투여전 최소한 10일 동안 어떠한 종류의 스테로이드도 투여하지 않았고, 치료기간 12일 동안 하루에 $500{\mu}g$과 $1000{\mu}g$을 Metered Dose Inhahler(MDI) 방법으로 투여하였다. Fluticasone propionate의 투여전과 투여후 3일, 6일, 9일 및 12일째 오전 8시에 혈철 코티솔을 측정하였고, 이와 동시에 24시간 소변을 채취하여 요중 유리 코티솔 농도를측 정하였다. 결 과 : $500{\mu}g$/day 투여군에서는 투여하기 전의 혈철 및 24시간 요중 유리 코티솔 농도는 투여기간 및 투여 후와 비교시 변화를 보이지 않았다. $1000{\mu}g$/day 투여군에서는 혈철 코티솔 농도는 투여 9일 그리고 12일째 (p<0.05). 24시간 요중 유리 코티솔 농도는 투여 3일 그리고 12일째 유의있는 감소(p<0.05)를 보였으며, 전반적으로 투여전과 비교시 투여기간에 따른 혈청 및 24시간 요중 유리 코티솔 농도의 감소를 보였다. 결 론 : 이상의 결과로, 단기간 하루 $500{\mu}g$의 fluticasone propionate 투여는 내인성 코르티솔 생산에 영향을 주지 않지만, 하루 $1000{\mu}g$의 fluticasone propionate투여는 내인성 코리티솔 생산에 유의한 영향을 미치는 것으로 사료된다.

Objective: This study was performed to determine the effects of stress after road transportation and oral administration of chromium and meloxicam on growth performance, plasma cortisol, serum metabolites, and behavior in dairy calves. Methods: A total of 50 Holstein heifers (average body weight [BW]: 172±4.19 kg; average age: 5.53±0.12 months) were randomly assigned to five groups including NL (not transported + D-lactose; 1 mg/kg BW), TL (transported + D-lactose; 1 mg/kg BW), TC (transported + chromium; 0.5 mg/kg dry matter [DM] feed), TM (transported + meloxicam; 1 mg/kg BW), and TMC (transported + combination of meloxicam and chromium; 1 mg/kg BW and 0.5 mg/kg DM, respectively). Doses of D-lactose monohydrate, meloxicam, and chromium were prepared for oral administration by suspension in 15 mL of water in a 20-mL dosing syringe. Blood was collected before transportation, immediately after 120 km of transportation (IAT), and at 6, 24, and 48 h after transportation. Results: Neither transportation nor administration of meloxicam and/or chromium affected (p = 0.99) average daily gain and feed intake. Plasma cortisol concentrations in the NL group (average 0.13 and 0.18 nmol/L, respectively) were lower (p<0.001) compared to the TL group (average 0.39 and 0.61 nmol/L, respectively) at IAT and 48 h after transportation. At 48 h after transportation, cortisol concentrations were lower (p<0.05) in the TC group (average 0.22 nmol/L) than in the TL group (average 0.61 nmol/L), and TC calves had similar cortisol concentrations to NL calves. Lying duration (min/d) was shorter (p<0.05) in the TL group than in the NL group at 2 d after transportation. Lying duration was longer (p<0.05) for the TC and TMC groups than for the TL group at 2 d after transportation. Conclusion: Transportation increased cortisol concentrations and affected lying behavior, while chromium administration reduced cortisol concentrations and changed lying behavior. Thus, chromium administration before transportation may be a viable strategy to alleviate stress elicited by road transportation.

Stress response to the seawater acclimation in coho salmon (Oncorhynchus kisutch) smolt was investigated. Salt concentration of rearing water was gradually increased for 3 days from freshwater to seawater (30 ppt salt level). The changes of serum concentrations of cortisol as a primary stress indicator, and as secondary indicators, glucose (GLC), lactate (LAC), triglyce.ide (TG), cholesterol (CHOL), sodium ion $(Na^+)$, chloride ion $(Cl^-)$ and enzyme activities (alanine aminotransferase, ALT: aspartate aminotrasferase, AST; lactate dehydrogenase, LDH) were quantified during the acclimation experiment. Among them, cortisol, LAC, TG, CHOL, ALT, AST concentrations showed rapid increase at the first exposure to the 10ppt salt level (day 1), and began to decrease to the constant values after day 2 of adaptation at 20ppt salt level. However, LDH concentration tended to decrease during the whole experimental period. $Na^+\;and\;Cl^-$ showed slight decrease at day 1, and increased to a little bit higher values after day 2 rather than those in freshwater. All the fishes started on taking a food after day 4 of seawater adaptation. From these results, to reduce osmotic shock inducible stress to fish in seawater acclimation, gradual increase of salt levels is recommended.

Background: Cushing syndrome is characterized by glucose intolerance, cardiovascular disease, and an enhanced systemic inflammatory response caused by chronic exposure to excess cortisol. Eosinopenia is frequently observed in patients with adrenal Cushing syndrome, but the relationship between the eosinophil count in peripheral blood and indicators of glucose level in patients with adrenal Cushing syndrome has not been determined. Methods: A retrospective study was undertaken of the clinical and laboratory findings of 40 patients diagnosed with adrenal Cushing syndrome at Chungnam National University Hospital from January 2006 to December 2016. Clinical characteristics, complete blood cell counts with white blood cell differential, measures of their endocrine function, description of imaging studies, and pathologic findings were obtained from their medical records. Results: Eosinophil composition and count were restored by surgical treatment of all of the patients with adrenal Cushing disease. The eosinophil count was inversely correlated with serum and urine cortisol, glycated hemoglobin, and inflammatory markers in the patients with adrenal Cushing syndrome. Conclusion: Smaller eosinophil populations in patients with adrenal Cushing syndrome tend to be correlated with higher levels of blood sugar and glycated hemoglobin. This study suggests that peripheral blood eosinophil composition or count may be associated with serum glucose levels in patients with adrenal Cushing syndrome.

The purpose of this study was to evaluate the bioequivalence of the test (Daewoo Hydrocortisone 10 mg, Daewoo Pharm. Co., Busan, Korea) and reference (Jenapharm Hydrocortisone 10 mg, JayTech Biogen, Seoul, Korea) hydrocortisone tablets. Twenty-four healthy male Korean volunteers were divided into two groups with a randomized $2{\times}2$ cross-over design. In order to suppress the endogenous cortisol secretion, a single oral dose of Dexamethasone (4 mg) was administered 10 hr prior to hydrocortisone administration. Blood samples were withdrawn for 10 hr at the predetermined intervals after a single oral dose of hydrocortisone (20 mg). The serum concentration of hydrocortisone was analyzed by HPLC/UV using a column switching method after liquid-liquid extraction process. The pharmacokinetic parameters ($AUC_{0{\sim}10hr}$, $C_{max}$, and $T_{max}$) of the test and reference hydrocortisone tablets were determined while the secretion of endogenous cortisol was being suppressed. The pharmacokinetic parameters of the test tablet were not statistically different from those of the reference tablet at ex value was 0.05. The 90% confidence intervals for the average ratio (test/reference) of $AUC_{0{\sim}10hr}$ and $C_{max}$ were within the Korea Food and Drug Administration acceptance range of 0.80-1.25 ($0.89{\sim}0.99$ and $0.86{\sim}0.99$ for $AUC_{0{\sim}10hr}$ and $C_{max}$, respectively). Therefore it was concluded that the test tablet, Daewoo Hydrocortisone tablet was bioequivalent to the reference tablet, Jenapharm Hydrocortisone tablet.
