Danggui leaf (Angelica acutiloba Kitagawa) has numerous dietary fiber and healthy functional properties such as anti-inflammatory activity. However, it is usually discarded after its roots are harvested. For wide application of danggui leaf, squeezed danggui leaf juice was used for making pan bread. Treatments included imported wheat flour (IMWF) and domestic wheat flour (DOWF) as a control, 1% soluble solid contents of squeezed danggui leaf juice instead of wheat flour (1% SDLJ), 2% SDLJ, 3% SDLJ, and 4% SDLJ. In the fermentation expansion, dough volume was not significantly different between DOWF and 1% SDLJ, whereas it decreased according to increased amount of squeezed danggui leaf juice. Regarding physical properties, springiness and cohesiveness decreased according to increased amount of squeezed danggui leaf juice and longer storage period. Gumminess, brittleness, and hardness increased according to increased amount of squeezed danggui leaf juice, although these were not statistically different among IMWF, DOWF, and 1% SDLJ after making pan bread. Principal component analysis (PCA) was performed to assess the correlation between storage period and physical properties. In the PCA, variance proportion of principal component (PC) 1 was 0.87 while that of PC 2 was 0.10. Further, 1% SDLJ showed similar results as DOWF and INWF after making pan bread and after 3 days of storage. In conclusion, use of 1% SDLJ is desirable for making squeezed danggui leaf juice.

Gallstone is the most common disease of the biliary system. Korean has experienced an increase in the percentage of cholesterol gallstones. The major risk factors associated with cholesterol gallstones are age, gender as well as obesity. This study was designed to determine the prevalence of gallstones in the last three years and evaluate the associated risk factors in the population who underwent health screening. The study population consisted of 2,484 males and 2,212 females who visited the health promotion center in Dalseogu, Daegu in Korea from January 2011 to December 2013. Each participant in the study had their biliary system gallbladder examined using ultrasonography. Classified as underweight, normal weight or overweight using the population of obese according to the body mass index, and classified according to mood diagnosis of diabetes presented by the American Diabetes Association. Fasting blood glucose and number of liver function, the divided the control group by referring to the normal liver function values used herein. The geological map, I was classified as NCEP APT III. A showed of total 148 people were found to have gallstones. The prevalence of sex among 148 patients (3.15%) 84 men (1.79%) and 64 women 1.36%) which shows significantly there is little difference. 1.84% 40 years and below, 3.38% 40's showed age prevalence was 4.66% in 50's and above. In addition, Total-cholesterol was at the most in 52 people, LDL-cholesterol in 398 people, Triglyceride in 36 people, HDL-cholesterol in 19 people. The abnormal group, was created from the total-cholesterol categories from a physical examination of a subject that has been found to be gallstones in the gallbladder. A result of conducting the univariate analysis shows the prevalence of gallstones, a correlation that is meaningful. The logistic regression analysis of multiple ages was chosen to show risk factors age independent cholelithiasis. In spite of the conclusion, gallstones are not displayed in relation to the metabolic syndrome but in order to clarify this, not only the subject of a health examination is needed but, a further study of the general public when possible.

This study has been carried out to secretion antibodies for the purpose of preventing the infection of Helicobacter pylori and using them as a supplement for treatment. This experiments have been separated antigens from H. pylori and observed into antibody production and the agglutination of H. pylori for the separated antigens. As major antigenic proteins separated from H. pylori, the following could be verified: 12 kinds of band for whole cell (WC), seven kinds of band for outer membrane protein (OMP), three kinds of band for crude urease, and one kind of band for lipopolysaccharide (LPS). The IgG anti-H. pylori antibody of separated antigens showed $77.9{\pm}6.4{\mu}g/ml$ for we (L), $84.9{\pm}6.4{\mu}g/ml$ for OMP, and $123.8{\pm}2.9{\mu}g/ml$ for crude urease, at the same antigen concentration of $20{\mu}g/100ull$, which showed the most at the crude urease. And it turned out that the IgA antibodies were generated with $2.5{\pm}0.32{\mu}g/ml$ for WC (L), $2.0{\pm}0.43{\mu}g/ml$ for OMP, and $1.3{\pm}0.25{\mu}g/ml$ for crude urease, which demonstrated the most for WC (L) antigens. As a result of verifying the immunogenecity of antigenic protein through the Western blotting, major antigenic substances could be confirmed as follows: 10 kinds for WC, six kinds for OMP and three kinds for crude urease. The agglutination values on the H. pylori of the antibody were $2^5,\;2^5,\;2^6\;and\;2^7$ at the antigen serums of anti-WC (H), anti-WC (L), anti-OMP and anti-crude urease, respectively, which indicated the highest for the antigen serum of anti-crude urease. The urease activation-inhibiting absorbance of antigen serum created by each antigen was $0.14{\pm}0.01$ for WC (H), $0.16{\pm}0.01$ for WC (L), $0.18{\pm}0.03$ for OMP, and $0.18{\pm}0.04$ for urease, demonstrating a significant inhibiting effect, compared with $0.26{\pm}0.02$ of the control group.

Objective: The purpose of this study was to compare the cephalometric measurements of obese and non-obese Korean male patients with obstructive sleep apnea syndrome (OSA). Methods: Eighty-seven adults who had visited the Sleep Disorder Clinic Center in Keimyung University, Daegu, Korea were examined and evaluated with polysomnography (PSG) and lateral cephalogram. They were divided into 4 groups (non-obese simple snorers, obese simple snorers, non-obese OSA patients, obese OSA patients) according to AHI (Apnea-Hypopnea Index) and BMI (Body Mass Index). Results: The obese OSA group had the highest AHI among the 4 groups. The non-obese OSA group had a significantly steeper mandibular angle and shorter tongue length than the obese OSA group. The hyoid bone of the obese OSA group was positioned anterior and inferior as compared with the non-obese OSA group. Multiple regression analysis showed that tongue length in the obese OSA group and retroposition of hyoid bone in the non-obese OSA group were significant determinants for the severity of AHI. Conclusions: From a cephalometric point of view, the obese and non-obese pateints with OSA may be characterized by different pathogeneses. Therefore, they have to be managed by individualized treatment. For the obese OSA patients, weight control must be advised as a first choice and for the non-obese OSA patients, oral appliance, nasal CPAP, UPPP and others could be chosen according to the obstructive sites.

In order to use the excellent features of saponin and phenolic compounds in the leaf and fruit of ginseng, ginseng fruit Yakgwa (GFY), ginseng leaf Yakgwa (GLY) and ginseng root Yakgwa (GRY) were made via adding the fruit, leaf and root powder in the process of making Yakgwa, and the properties were investigated. When making Yakgwa, GFY and GLY had superior expansion compared to GRY. 2.5-GFY (added 2.5% ginseng fruit powder) and 2.5-GLY (added 2.5% ginseng leaf powder) increased about 1.68 times and had better expansion than the control; however, when more amount of fruit and leaf were added, the expansion was decreased. The GFY and GLY showed green and red color, and the brightness and yellowness were decreased. Oil absorption during making Yakgwa showed to increase as the amount of fruit and leaf powder were increased regardless of the ginseng parts. Hardness of Yakgwa increased as the root additives were increased, and it decreased when leaf and fruit were added. The results of sensory evaluation on ginseng-based Yakgwa showed that oily taste was lowered as the amount of fruit and leaf additives were increased, which had increased the preference. On the overall preference of Yakgwa, 5.0-GFY, 2.5-GLY and 7.5-GRY was high, which contained 2.30 mg/g, 1.02 mg/g, and 0.91 mg/g of saponin, respectively.

Purpose: From August 2017, hospice-palliative care (HPC) will be provided to patients with acquired immunodeficiency syndrome (AIDS), chronic obstructive pulmonary disease (COPD), and liver cirrhosis in Korea. To contribute to building a non-cancer (NC) hospice-palliative care model, NC specialists were interviewed regarding the goals, details, and provision methods of the model. Methods: Four physicians specializing in HPC of cancer patients formulated a semi-structured interview with questions extracted from literature review of 85 articles on NC HPC. Eleven NC disease specialists were interviewed, and their answers were analyzed according to the qualitative content analysis process. Results: The interviewees said as follows: It is difficult to define end-stage NC patients. HPC for cancer patients and that for NC patients share similar goals and content. However, emphasis should be placed on alleviating other physical symptoms and emotional care rather than pain control. Timing of the care provision should be when patients are diagnosed as "end stage". Special issues should be considered for each NC disease (e.g., use of anti-retroviral drugs for AIDS patients, oxygen supply for COPD patients suffering from dyspnea, liver transplantation for patients with liver cirrhosis) and education should be provided to healthcare professionals. NC patients tend to negatively perceive HPC, and the government's financial assistance is insufficient. Conclusion: It is necessary to define end-stage NC patients through in-depth discussion to minimize issues that will likely accompany the expansion of care recipients. This requires cooperation between medical staff caring for NC patients and HPC givers for cancer patients.

This study was to examine impacts of turbid water on fish community in the downstream of Yongdam Dam during the period from June to October 2006. For the research, we selected six sampling sites in the field: two sites were controls with no influences of turbid water from the dam and other remaining four sites were the stations for an assessment of potential turbid effects. We evaluated integrative health conditions throughout applications of various models such as necropsy-based fish health assessment model (FHA), Index of Biological Integrity (IBI) using fish assemblages, and Qualitative Habitat Evaluation Index (QHEI). Laboratory tests on fish exposure under 400 NTU were performed to find out impact of turbid water using scanning electron microscope (SEM). Results showed that fine solid particles were clogging in the gill in the treatments, while particles were not found in the control. This results indicate that when inorganic turbidity increases abruptedly, fish may have a mechanical abrasion or respiratory blocking. The stream health condition, based on the IBI values, ranged between 38 and 48 (average: 42), indicating a "excellent" or "good" condition after the criteria of US EPA (1993). In the mean time, physical habitat condition, based on the QHEI, ranged 97 to 187 (average 154), indicating a "suboptimal condition". These biological outcomes were compared with chemical dataset: IBI values were more correlated (r=0.526, p<0.05, n=18) with QHEI rather than chemical water quality, based on turbidity (r=0.260, p>0.05, n=18). Analysis of the FHA showed that the individual health indicated "excellent condition", while QHEI showed no habitat disturbances (especially bottom substrate and embeddeness), food-web, and spawning place. Consequently, we concluded that the ecological health in downstream of Yongdam Dam was not impacted by the turbid water.

Enhancement mechanistic actions of testosterone (TS) productions in mouse Leydig TM3 cells by the eritadenine (EA) and/or the Agaricus blazei mycelial liquid culture extract (ABMLCE). Productions of TS in TM3 cells were investigated in normal and oxidative-stressed culture conditions. In the normal culture condition, TM3 cells grown in a Dulbecco's Modified Eagle's Medium (DMEM) were treated with EA (0~100 ppm) and ABMLCE (10 ppm) + EA (0~50 ppm) for 24 hr, and in the oxidative-stressed culture condition, the cells grown in DMEM containing $50{\mu}M$ $H_2O_2$ to induce oxidative stress for 4 h were treated with the same as those in the normal culture condition. TS content, $3{\beta}$-hydroxysteroid dehydrogenase 2 (HSD3B2) enzyme activity, $5{\alpha}$-reductase 2 ($5{\alpha}-R2$) enzyme activity, and free-radical nitric oxide (NO) content in the culture media were measured using their corresponding assay kits. EA, ABMLCE, and ABMLCE + EA significantly, p<0.05, enhanced TS productions in both cultural conditions, relative to control treatment. The activity of the HSD3B2 enzyme, which is involved in the production of precursors for TS production, was elevated by EA, ABMLCE, and ABMLCE + EA treatments in both culture conditions. The activity of the $5{\alpha}-R2$ enzyme, which converts TS to dihydroxytestosterone (DHT), was not significantly affected in either culture condition by EA, ABMLCE, or ABMLCE + EA treatments. The treatments included reduced NO content. These results indicate that EA, ABMLCE, and EA + ABMLCE treatments elevated TS in TM3 cells via the enhancements of HSD3B2 activity and the reduction of NO production, and also imply that EA and ABMLCE or EA + ABMLCE could be useful materials for the production of TS in humans.

Saccharin (o-benzoic sulfimide) is the first artificial and non-caloric sweetener that was first synthesized in 1879. In this study, we examined the biological activity of saccharin against various human cancer cell lines and human bone marrow-derived mesenchymal stem cells. A viability assay based on the conversion of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) was performed to test for the cytotoxicity of saccharin about the four human cancer cell lines (H460, H157, A549 and SKOV3), one murine cancer cellline (Raw264.7), and MSCs. In order to find the differentially expressed gene in saccharin-treated MSCs against untreated MSCs, we performed annealing control primer (ACP)-based differential display reverse transcriptionp-olymerase chain reaction (DDRT-PCR). All tested cells were treated with saccharin at various concentrations (0.0, 4.8, 7.2, 9.6, 12.0, 14.4 mg/mL) for 48 hr. The number of metabolically active cancer cells decreased when treated with the saccharin at various concentrations for 48 hr as compared with the untreated cells. The decrease in cell survival was more evident with increasing concentrations of saccharin. Moreover, novel candidate genes, which were differentially expressed in MSCs in response to saccharin, were identified in 16 bands on 2% agarose gel. This revealed 16-7 up-regulated and 9 down-regulated-differentially expressed genes indicated by arrows. One of these candidate genes was a FK506-binding protein gene. The functional roles of FK506 binding proteins, with respect to the activities of stem cell proliferation, were not characterized. Further studies are required to get a better understanding of FK506-binding proteins in its roles in increasing stem cell proliferative activities from using saccharin.
