Background: Surgical-site, multimodal drug injection has recently evolved to be a safe and useful method for multimodal pain management even in patients with musculoskeletal trauma. Methods: Fifty consecutive patients who underwent plating for mid-shaft and distal clavicular fractures were included in the study. To evaluate whether surgical-site injections (SIs) have pain management benefits, the patients were divided into two groups (SI and no-SI groups). The injection was administered between the deep and superficial tissues prior to wound closure. The mixture of anesthetics consisted of epinephrine hydrochloride (HCL), morphine sulfate, ropivacaine HCL, and normal saline. The visual analogue scale (VAS) pain scores were measured at 6-hour intervals until postoperative hour (POH) 72; stress biomarkers (dehydroepiandrosterone sulfate [DHEA-S], insulin, and fibrinogen) were measured preoperatively and at POH 24, 48, and 72. In patients who wanted further pain control or had a VAS pain score of 7 points until POH 72, 75 mg of intravenous tramadol was administered, and the intravenous tramadol requirements were also recorded. Other medications were not used for pain management. Results: The SI group showed significantly lower VAS pain scores until POH 24, except for POH 18. Tramadol requirement was significantly lower in the SI group until POH 24, except for POH 12 and 18. The mean DHEA-S level significantly decreased in the no-SI group ($74.2{\pm}47.0{\mu}g/dL$) at POH 72 compared to that in the SI group ($110.1{\pm}87.1{\mu}g/dL$; p = 0.046). There was no significant difference in the insulin and fibrinogen levels between the groups. The correlation values between all the biomarkers and VAS pain scores were not significantly different between the two groups (p > 0.05). Conclusions: After internal fixation of the clavicular fracture, the surgical-site, multimodal drug injection effectively relieved pain on the day of the surgery without any complications. Therefore, we believe that SI is a safe and effective method for pain management after internal fixation of a clavicular fracture.

The purpose of this study was to examine the changes of body composition and aging-related hormones by rhythmic exercise in elderly women. The subjects in this study were 20 olders living in a rural community, >60 years of age and were performed rhythmic exercise program during 12 weeks. The measurement of the body composition, body mass (t=3.125, p=.006), body mass index (t=3.225, p=0.004), body fat mass (t=3.782, p=0.001), waist-to-hip ratio (t=3.867, p=0.001) were significant difference after exercise program, but had no effect on lean body mass. Also, growth hormone (t=-2.221, p=0.039) and somatomedin-C (t=-9.186, p=0.000) were significantly increased after rhythmic exercise, however, rhythmic exercise had no effect on DHEA-S. These results suggest that rhythmic exercise appeared to effect of control on body composition and some aging-related hormones in elderly women.

Purpose: Fatigue, energy loss, feeling of helplessness, poor appetite, pain besides general weakness are major symptoms presented to terminally ill cancer patients. These symptoms are similar to those that appeared with adrenal insufficiency. Also, for terminally ill cancer patients who are hospitalized for palliative care, opioid agents are prescribed to control moderate to severe pain. We studied the relationship of opioid agents and adrenal insufficiency. Methods: From November 2013 through June 2014, we monitored the serum level of cortisol and dehydroepiandrosterone sulfate (DHEAS, serum) in 55 cancer patients who were over 18 years old and were treated at a hospice center. We also checked the treatment period and dosage of opioid agents. Results: The DHEAS level, treatment period and dosage of opioid agents did not have significant correlation. Correlation between the serum cortisol level and the opioid agent treatment period was not significant either, but the serum cortisol level was positively correlated with the dosage of opioid agents (P value 0.0322). Conclusion: This study did not identify a novel link between treatment period, dosage of opioid agents and adrenal insufficiency. But, the DHEAS level was mostly below the normal level in patients who were treated with opioid agents.

Carcass weight and backfat thickness are primary yield grading factors. Insulin-like growth factor (IGF)-I/-II, transforming growth factor $\beta$1 (TGF-$\beta$1), and epidermal growth factor (EGF) regulate the proliferation and differentiation of cells including adipocytes. Also, interleukin (IL)-2/-6, cortisol, and dehydroepiandrosterone-sulfate (DHEA-S) are known to be related to muscle growth and fat depth. However, the relationships between endocrine factors and carcass grade have not been studied. Therefore, this study aimed to measure the concentrations of endocrine factors in serum and muscle, and to investigate the relationship of endocrine factors with carcass grade. A total of 60 crossbred gilts (Duroc${\times}$Yorkshire${\times}$Landrace) were used. Blood from the jugular vein was collected at antemortem (7 days before slaughter) and postmortem periods, and M. Longissimus was collected at 45 min and 24 h after slaughter. The concentrations of IGF-I/-II, EGF, TGF-$\beta$1, IL-2/-6, cortisol and DHEA-S were analyzed by radioimmunoassay (RIA) or enzyme-linked immunosorbent assay (ELISA). In general, IGF and EGF concentrations in serum and muscle of grade A carcasses were found to be higher than those of grade C carcasses at antemortem and postmortem periods, whereas the pattern of TGF-$\beta$1 concentration was reversed. In particular, the concentrations of muscle IGF-I (24 h postmortem) and serum TGF-$\beta$1 (antemortem) were significantly different between grades A and C (p<0.05). The present results indicate that serum and muscle growth factors affect carcass weight and backfat thickness, and indirectly suggest the possibility that carcass grade could be predicted by expression of serum and/or muscle growth factors.

With an aim of obtaining high efficacy in cartilage regeneration, implantable polymeric rods were fabricated. These rod-type matrices were anticipated to perform structural tissue supporting activity and enhance extracellular matrix (ECM) formation by releasing specific agent, DHEA-S, in controlled manner. It is expected that application for the drilling operation on the articular cartilage of OA patients as the implants may promote regeneration of their cartilage. Osteoarthritis (OA) is a degenerative joint disease characterized by progressive loss of articular cartilage, subchondral bone remodeling, spur formation, and synovial inflammation. (omitted)

Several studies have been done regarding carcass traits and growth in pigs. Recently, these have progressed to examine increases in economic traits, including meat quality and meat quantity, by using candidate genes. One of them is the pituitary-specific protein PIT-1, a member of the POU (Pit-Oct-Unc) family of transcription factors playing an important regulatory role in developmental processes. In addition, muscle development is known to be regulated in part by growth factors and cytokines locally produced. Therefore, studies were performed to analyze PIT-1 genotypes and serum cytokines (IGF-I, IGF-II, TGF-${\beta}1$, EGF, cortisol, DHEA-S, IL-2, and IL-6) in castrated male pigs for their possible involvement in the development of carcass traits. The genotypes of PIT-1 gene were analyzed by PCR-RFLP with MspI restriction enzyme. But, only CD and DD genotypes, not CC genotype, have been detected. Based on PIT-1 genotyping, a significant difference in EGF expression beween CD type (78.8 ng/ml) and DD type (46.0 ng/ml) was detected (p<0.05), whereas other cytokines did not show any statistical significance depending on PIT-1 genotypes. Collectively, these results suggest the possibility that EGF could affect the formation of carcass traits.

Objective: To assess the difference of baseline hormonal status and pathophysio logy, and confirm the risk factors for long term complication according to Body Mass Index in women with polycystic ovary syndrome. Materials and Methods: Serum level of LH, FSH, Estradiol, Prolactin, Testosterone, DHEA-S, fasting insulin were measured and 100 gm oral glucose tolerance test and endometrial biopsy were performed in total 75 chronic anovulation patients and 20 normal cycling infertility patients. 95 evaluated patients were divided into 3 groups including patients with chronic anovulation having BMI below 25, BMI beyond 25.1, normal cycling infertility patients, Group 1 (n=39), Group 2 (n=36), Group 3 (n=20), respectively. Statistical analysis was performed respect to relationship between BMI and measured hormone level, sum of glucose level during 100 gm OGTT, insulin resistance using t-test, ANOVA test, Post Hoc test, Mann-Whitney test. p<0.05 was considered as statistically significant. Results: Serum LH level and LH/FSH ratio was significantly higher in Group 1, compared than Group 2 or 3 (p<0.05), BMI and LH, LH/FSH ratio was negatively correlated (r=-0.351, r=-0.318). There was no significant difference according to BMI in FSH, testosterone, estradiol, prolactin, DHEA-S level. Fasting insulin and sum of glucose level during 100 gm OGTT were significantly higher in Group 2 compared than Group 1 or Group 3 (p<0.05), there was no significant difference between Group 1 and Group 3. Insulin resistance was more frequently identified in Group 2 compared than Group 1 (p=0.001). Conclusions: BMI and LH, LH/FSH ratio were negatively correlated, so clinical significance of LH, LH/FSH ratio in diagnosis of PCOS may be attenuated by increasing body weight. Overweight patients with chronic anovulation may be the risk group for developing insulin resistance, hyperinsulinemia, glucose intolerance, later type 2 DM. Hyperinsulinemia may operate mainly in overweight chronic anovulation patients in development of hyperandrogenism.

For the development of drugs for alzheimer,s disease, the study was done to review the oriental pathology, clinical data, recent trends for research and strategy for future study. The results were as follows: 1. The medical term Chi-dsi implying alzheimer,s disease was referred for the first time in a medical book, Hwatasheneubijeon written by Hwa-Ta and its differentiation and treatment were studied more in Ming or Ching dynasties. Chi-dai can be differentated as weak(虛) syndrome and Shi(實) syndrome. This can be caused by deficiencies of renal Yin, renal Yang, cardiac Yin and hepatic blood, while that by deficiencies of pathological fluid(痰飮) and clotted blood(瘀血). 2. Dementia can be roughly classified as alzheimer's disease and multi-infarct disease. Its causes were known to be cholinergic transmitter, C-peptide, amyloid-${\beta}$, apolipoprotein, APP(amyloid precursor protein), TGF, MMP-9 and free radical. 3. In Korea experimental studies were chiefly done for the elimataion of C-peptide, amyloid-${\beta}$, apolipoprotein, APP for alzheimer's disease, for the development of drug inhibiting degerative change following CVA and loss of memory and also administrative measure was done by support of government. 4. Drugs of dimentia developed so far were Chi-Dai dan, extracts from aloe, mushroom, green tea, Ganoderma and also folic acid, vitamin C, DHEA and silk amino acid were reported to be effective in dimenta. 5. Future strategic research had better be done on dementia-inducing factors such as acetylcholine, C-peptide, amyloid-${\beta}$, apolipoprotein, APP, TGF, MMP-9 and free radical, development of animal model for dimentia, clinical study, epidemiology, nursing and administrative studies and also consortium for dimentia research should be formed so that repeated investment be avoided.

In order to define the clinical characteristics of Korean women with polycystic ovary syndrome, clinical symptoms, biochemical features and ultrasonographic findings were determined in ninety PCO patients. Frequency of clinical manifestations were as follows:acne 42%, overweight 31 %, oily skin 14 %, hirsutism 10%. Relatively low frequencies of hirsutism is recognized in patients with Korean PCO syndrome. Mean(${\pm}$S.E.) of each hormone was:testosterone 1.18${\pm}$1.07ng/ml, LH 21.47${\pm}$${\pm}$2.6mIU/ml, FSH 7.26${\pm}$2.67mIU/ml, LH/FSH ratio 2.94${\pm}$1.29, prolactin 25.48${\pm}$46.33ng/ml, DHEA-S 333.78${\pm}$309.60ng/dl, 17-0HP 1.72${\pm}$1.74ng/ml. Mean 17-OHP after ACTH stimulation test was 5.07${\pm}$12.01ng/ml. Ultrasonographically measured mean ovarian volume were $11.02{\pm}5.92cm^3$ in right and $9.23{\pm}5.64cm^3$ in left and small sized multiple subcapsular follicular cysts were noted in 43 patients (47.9%) with PCO syndrome.

This study was carried out to investigate the effect of short-term thermal stress on the serum concentrations of cortisol and DHEAS in BALB / c male mice. Cortisol and DHEAS concentrations in serum were measured by radioimmunoassay(RIA). We found there were significantly increased in the cortisol levels in 30 min-stressed group(T30) compared with control group(p＜0.01), and then declined without significance in 120 min-stressed group (T120) compared with T30. By contrast, DHEAS levels were decreased without significance in both T30 and T120 compared with control group. Though short-term thermal stress, the continuous decline of DHEAS levels were observed. These results show that short-term thermal stress affects the serum levels of cortisol and DHEAS in mice. Furthermore, we found that DHEAS is a stress-related hormone and will be able to utilize as a stress marker.
