  • Objective : Cortex of Ulmi pumilae(CUP) has been used to treat several diseases including boil, swelling, and scabies etc. Recently, CUP was known to have wrinkle care and whitening actions. But, It's exact mechanisms are unclear. Methods : The present study was designed to investigate effects of CUP on Human HaCaT keratinocyte and malignant melanoma cells such as SK-MEL-2 and B16F10 in terms of cell viabilities, proliferations, DPPH free radical scavenging activities, oxygen free radical productions and inhibitory action on elastase activities. Results : CUP accelerated proliferation of HaCaT keratinocytes in the lower concentration. CUP also prevented cell death of HaCaT induced by Hydrogen peroxide, which products oxygen free radicals. On the contrary, CUP did not affect proliferations of SK-MEL-2 or B16F10. Futhermore, CUP showed inhibitory action against SK-MEL-2 proliferation at the concentration of $500{\mu}g/m{\ell}$ In addition, CUP was shown to have DPPH free radical scavenging activities and also have inhibitory effects on elastase activities too. On the fluorescent examinations, the present author knows that CUP elevated production levels of oxygen free radicals in malignant melanoma cell, SK-MEL-2. Conclusions : These results suggest that CUP has possibilities of usage for functional cosmetics which have wrinkle care and whitening activities and related mechanisms are involved in inhibition of elastase action and acceleration of oxidative stress in melanoma cell.

  • BACKGROUND: It is essential to prioritize the exact and clear understanding of agricultural nonpoint source pollution (NPS) controls. The realistic policies and systems should also be developed based on this understanding. Therefore, this study aimed to present agricultural Best Management Practices (BMPs) applicable for the fields based on the Delphi survey result. METHODS AND RESULTS: This study deduced the evaluation items to assess each BMP for agricultural NPS control and conducted the surveying using the Delphi method based on agricultural BMP experts. In addition, its on-the-spot application were evaluated. Considering its importance, technical, social and economic proprieties showed that political support was ranked first and followed by cost investment, labor investment, reduction effect and resident participation. The survey findings by agricultural BMP experts showed the good performance of on-the-spot application can be achieved from fertilization by soil testing, residue and green manure application and contour plowing which are applicable within a field. Agricultural BMPs, highly applicable for the fields, were the countermeasures that farmers who are the principal bodies of agricultural NPS control could be participated directly. CONCLUSION: The active participation of farmers is essential for effective control of agricultural NPS. It is necessary to establish various incentive systems.

  • Background The technique of delayed-immediate breast reconstruction includes immediate insertion of a tissue expander, post-mastectomy radiation, followed by reconstruction. The aesthetic benefits of delayed-immediate reconstruction compared to delayed reconstruction are postulated but remain unproven. The purpose of this study was to compare aesthetic outcomes in patients following delayed and delayed-immediate autologous breast reconstruction. Methods A retrospective analysis was performed of all patients who underwent delayed or delayed-immediate autologous breast reconstruction by the senior author from 2005 to 2011. Postoperative photographs were used to evaluate aesthetic outcomes: skin quality, scar formation, superior pole contour, inferior pole contour, and overall aesthetic outcome. Ten non-biased reviewers assessed outcomes using a 5-point Likert scale. Fisher's Exact and Wilcoxon-Mann-Whitney tests were used for comparative analysis. Results Patient age and body mass index were similar between delayed (n=20) and delayed-immediate (n=20) cohorts (P>0.05). Skin and scar quality was rated significantly higher in the delayed-immediate cohort (3.74 vs. 3.05, P<0.001 and 3.41 vs. 2.79, P<0.001; respectively). Assessment of contour-related parameters, superior pole and inferior pole, found significantly improved outcomes in the delayed-immediate cohort (3.67 vs. 2.96, P<0.001 and 3.84 vs. 3.06, P<0.001; respectively). Delayed-immediate breast reconstruction had a significantly higher overall score compared to delayed breast reconstructions (3.84 vs. 2.94, P<0.001). Smoking and the time interval from radiation to reconstruction were found to affect aesthetic outcomes (P<0.05). Conclusions Preservation of native mastectomy skin may allow for improved skin/scar quality, breast contour, and overall aesthetic outcomes following a delayed-immediate reconstructive algorithm as compared to delayed breast reconstruction.

  • Objective : This study was designed to investigate the possibility of AR for chronic renal injury. Methods : The author first investigated the expression levels of DNA by inducing of chronic renal injury. Then, the author investigated the effects of AR on chronic renal injury induced by combination treatment with Adriamycin and cisplatin in terms of changes in body weights and renal tissues, urine volume, BUN and creatinine levels, creatinine clearance and histopathological changes in renal tissues. Total expression levels of 546 genes were elevated or lowered by induction of chronic renal injury. Genes of which whose expression levels were elevated by induction of chronic renal injury were related to the PPAR signaling pathway and fatty acid mechanism, etc. Genes of which expression levels were lowered by induction of chronic renal injury were related to the neuroactive ligand-receptor signaling pathway. Results : Oral administration of AR restored renal mass which was reduced by induction of chronic renal injury. AR also restored creatinine clearance and lowered serum BUN level. In histopathological observation, the AR group has a tendency to prevent tissue damages as shown in the chronic renal injury group. Conclusions : AR can be used to treat patients with chronic renal injury although further study will be needed to elucidate the exact mechanisms in the efficacy of AR on chronic renal injury.

  • Objectives : Auklandia Lappa (ALE) is one of the herbs used frequently to treat abdominal pain and diarrhea and reported anti-inflammatory activity by suppressing proinflammatory cytokines. This study was designed to investigate whether ALE could show protective activities on experimental colitis induced by dextran sulfate sodium (DSS) models. Methods : Colitis was induced by DSS in Balb/c mice. ALE 10, 30, 100 and 300 mg/kg were orally administered twice a day for 7 days in DSS model. Mice weight was measured daily. Scoring of clinical findings was measured every other day. Colon length, edema, fecal blood and histological damages were assessed at day 7 in DSS model. In histological analysis, we checked cryptal glands, surface epithelium, submucosa, transmural, stroma and scored degree of inflammatory cell damage by modified histological scoring. We also calculated cytokines concentrations including IFN-${\gamma}$, TNF-${\alpha}$, IL-6, IL-$1{\beta}$, IL-17, IL-23, IL-10 and TGF-${\beta}1$ by Biometric Multiplex Cytokine Profiling method. Results : ALE showed the protective effects on DSS-induced experimental colitis. ALE inhibited shortening of colon length and histological damages of colon does-dependently, but it did not inhibit weight loss. ALE also inhibited IFN-${\gamma}$ and IL-6 expression, and upregulated cytokines (IL-10, TGF-${\beta}1$) related to regulatory T cell differentiation and proliferation. Conclusions : The current results demonstrate the clinical utility of ALE in traditional medicine and indicate the possibility of potent drug development of inflammatory bowel diseases from natural products. Further investigations for exact mechanisms will be needed.

  • Purpose: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. Methods: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher' s-exact test and multiple logistic regression. Results: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). Conclusion: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.

  • Purpose: The aim of this study was to identify the level of Human papillomavirus (HPV) knowledge, intention of HPV vaccination, and barriers on HPV vaccination among male undergraduate students of Health department and Non-health department. Methods: A total of 149 male undergraduate students responded to self-administered questionnaires about their HPV knowledge, HPV vaccination intention, and their barriers on HPV vaccination. ANOVA, t-test and $x^2$ test (Fisher's exact test) were used for data analysis. Results: Mean score of HPV knowledge was $3.39{\pm}3.05$, and there was significant difference between Health department ($4.15{\pm}3.08$) and Non-health department ($2.58{\pm}2.82$) in HPV knowledge (t=3.241, p=.001). There was no significant difference in HPV vaccination acceptance between the two groups. The barriers on HPV vaccination were 'lack of information about HPV vaccine efficacy' and 'lack of information about HPV vaccination time and strategy', and there were significant differences in barriers on HPV vaccination between the two groups. Conclusion: The knowledge on HPV was low, and HPV vaccination was hindered due to lack of information about HPV vaccine despite their intention to obtain HPV vaccine. HPV education to promote HPV vaccination should be targeted among male students.

  • Purpose: The purposes of this study were to identify the prevalence and influencing factors of fecal incontinence, and to analyze the association between fecal incontinence and depression. Methods: The subjects of this study were 233 women living in rural areas, and data were collected using questionnaires from February 24 to May 30, 2012. Fecal incontinence was measured with the Continence Grading Score, and depression with the Geriatric Depression Scale. Collected data were analyzed using SPSS through $x^2$-test, Fisher's exact test, t-test and ANOVA. Results: Of the subjects, 16.7% had fecal incontinence. The prevalence of fecal incontinence was higher in older women ($x^2=23.55$, p<.001), those with vaginal delivery ($x^2=4.81$, p=.049), those with parity of 4 or more ($x^2=13.47$, p=.003), and those with urinary incontinence ($x^2=26.36$, p<.001). The level of depression was significantly higher in older women (F=19.27, p<.001), those with low academic qualification (F=18.17, p<.001), those with urinary incontinence (F=4.15, p=.043), and those with fecal incontinence (F=14.90, p<.001). Conclusion: These results suggest that there should be supports by public health care for fecal incontinence prevention and care programs in order to promote the physical and emotional health of rural women.

  • The purpose of this study was to help in explaining the necessity of education on complementary and alternative medicine(CAM) and opening relevant curriculums in nursing education by grasping the kinds of CAM in which nursing students want to be opened. Data were collected from September 27, 2003 through October 20, 2003. A group of 865 nursing students were surveyed using questionnaires in seven universities whose curriculums on CAM have not been available. Collected data were statistically analyzed by using SAS 8.02 system, and the study results are as follows: 1. The average of subjects' behavior toward CAM was 3.52 of the total 5 with practical affairs 3.79. medical treatment 3.79, social concerns 3.84, and communication 3.78. 2. Most nursing students $(90.6\%)$ did not precisely understand the meaning of CAM although they had heard of it. Most of them $(85.5\%)$ had no experience of applying CAM. The study also revealed that more qualified CAM lecturers in the future are needed: specialist in the relevant field $(83.2\%)$, doctor and herb doctor $(6.5\%)$, clinical nurse $(6.0\%)$ and professor of the department of nursing science $(4.3\%)$. 3. Concerning students' behavior toward CAM, there were statistically significant difference between students from agrarian and fishing villages (F=4.91. p=.007) and the others. 4. CAM courses that students want were therapeutic touch (massage) $(22.9\%)$. aroma therapy $(14.8\%)$, manual healing methods $(14.7\%)$, treatment of blood vessel $(8.3\%)$, foot reflexology $(7.9\%)$, and heart remedy $(6.8\%)$. In conclusion, the study indicated that nursing students had positive attitudes toward CAM and for this. healers should have a frank talk with patients in order to maximize symptom-relieving effects. However, the study showed that most nursing students did not understand the exact meaning of CAM. Considered the fact that improvement of both health status and quality of life will be an important issue in the future, active introduction and education of CAM in nursing curriculum are a matter of necessity.

  • Purpose: This study was conducted to compare self-care behaviors and self-care behavior related factors for groups of patients with good, inadequate and poor glycemic control. The study was based on variables of the Theory of Planned Behavior by Ajzen, habit and family support. (1991). Methods: Participants were 134 patients with type 2 diabetes (good glycemic control group: 57, inadequate glycemic control group: 40, poor glycemic control group: 37). Self-care behaviors, intention to self-care behavior and self-care behavior related variables (attitude, subjective norms, perceived behavior control, habits and family support) were measured. Data were collected from August 12 to September 25, 2014 and were analyzed using $x^2$-test, Fisher's exact test, ANCOVA, and logistic regression with SPSS/WIN 21.0. Results: Among the three glycemic groups, there were significant differences in self-care behavior, subjective norms, perceived behavior control, family support, and habits. Multinomial logistic regression showed that poor blood glucose probability was associated with duration of diabetes mellitus, method of DM therapy, perceived behavior control and habits. Conclusion: The study findings reveal the important role of self-care behavior, subjective norms, perceived behavior control, family support, and habits in blood glucose control in adults with type 2 diabetes.
