  • Recently, people are becoming fatter in most parts of the world. Obesity is regarded as an important risk factor to adversely affect the health of humans, associated with hypertension, hyperlipidemia, diabetes, and cardiovascular diseases. In the present study, therefore, we tested the short time efficiency and safety of Bangpoongtongsungsan as a drug to decrease body weight in subjects with obesity. A total 48 volunteers (24 man, 24 woman) with body mass index (BMI : weight in kg divided by square of height in meters) of $23㎏/m^2$ participated in clinical study for 12 weeks, from 2008, March 01 to 2008, Jun 30. The subjects was received a dietary supplement of 12 pieces hard capsules per day (4 pieces in one, 3 times in a day) during the clinical study. At the end of clinical study, body weight of subjects was significantly decreased from $72.21{\pm}11.44\;kg$ to $70.53{\pm}11.67\;kg$ (p<0.05). Waist circumferences of subjects were reduced $91.58{\pm}6.43\;cm$ to $85.25{\pm}7.70\;cm$ (p<0.05). Also, a BMI of subjects was significantly decreased $26.07{\pm}2.35\;kg/m^2$ to $25.63{\pm}2.63\;kg/m^2$ (p<0.05). Particularly, a decrease in body weight, waist circumferences, and BMI was more significant in woman than man. But, other biochemical levels including lipid and glucose in plasma had no changes at the end of clinical study. In conclusion, administration of Bangpoongtongsungsan in subjects with high body weight fat could inhibit obesity associated with a decrease in body weight, waist circumferences, and BMI.

  • Cancer is the leading cause of morbidity and mortality worldwide, characterized by irregular cell growth. Cytotoxicity or killing tumor cells that divide rapidly is the basic function of chemotherapeutic drugs. However, these agents can damage normal dividing cells, leading to adverse effects in the body. In view of great advances in cancer therapy, which are increasingly reported each year, we quantitatively and qualitatively evaluated the papers published between 1981 and December 2015, with a closer look at the highly cited papers (HCPs), for a better understanding of literature related to cytotoxicity in cancer therapy. Online documents in the Web of Science (WOS) database were analyzed based on the publication year, the number of times they were cited, research area, source, language, document type, countries, organization-enhanced and funding agencies. A total of 3,473 publications relevant to the target key words were found in the WOS database over 35 years and 86% of them (n=2,993) were published between 2000-2015. These papers had been cited 54,330 times without self-citation from 1981 to 2015. Of the 3,473 publications, 17 (3,557citations) were the most frequently cited ones between 2005 and 2015. The topmost HCP was about generating a comprehensive preclinical database (CCLE) with 825 (23.2%) citations. One third of the remaining HCPs had focused on drug discovery through improving conventional therapeutic agents such as metformin and ginseng. Another 33% of the HCPs concerned engineered nanoparticles (NPs) such as polyamidoamine (PAMAM) dendritic polymers, PTX/SPIO-loaded PLGAs and cell-derived NPs to increase drug effectiveness and decrease drug toxicity in cancer therapy. The remaining HCPs reported novel factors such as miR-205, Nrf2 and p27 suggesting their interference with development of cancer in targeted cancer therapy. In conclusion, analysis of 35-year publications and HCPs on cytotoxicity in cancer in the present report provides opportunities for a better understanding the extent of topics published and may help future research in this area.

  • This study was conducted to evaluate the association between periodontal disease and diabetes mellitus. The final analysis population of this study was composed of 4,830 adults with diabetes mellitus or periodontal disease and aged 19 years or older, based on the third-edition data of the 4th Korea National Health and Nutrition Examination Survey (KNHANES) (in 2009). Diabetic status and potential confounders were used in questionnaire materials and physical examination materials, and the presence of periodontal disease was used in the materials for oral health examination by a dentist. For diabetic status, fasting plasma glucose (FPG) levels <100 mg/dl were subcategorized into normal group and FPG levels ${\geq}100mg/dl$ into impaired fasting glucose group; glycosylated hemoglobin (HbA1c) levels <7% into normal group and HbA1c ${\geq}7%$ into diabetes group, on the basis of the American Diabetes Association. According to the 2009 Korea Health Statistics, the case where the pocket depth is 3 mm or more was defined as periodontal disease. The association between the two diseases was evaluated through $x^2$-test and logistic regression analysis using R-commander 2.14. In impaired fasting glucose group, community periodontal index (CPI) groups 3 to 4 had higher risks for periodontal disease 1.23 times (95% confidence interval, 1.07~1.42) than those of CPI groups CPI 0~2, even after adjustment for several confounders. In addition, periodontal disease and diabetes mellitus showed statistically significant differences depending on age, sex, income level, educational background, smoking status, alcohol consumption, and snack intake. The analyses of the third-edition data of the 4th KNHANES showed that there was a statistically significant association between periodontal disease and diabetes mellitus as examined by means of CPI in this study.

  • This study analyzed the relationships mother's discipline style, preschooler's emotional regulation strategies, and preschooler's leadership. The subjects were 180 preschoolers who were 5 years old and their mothers live in Gwang-ju and Jeon-Nam province. Collected data were analyzed by descriptive statistics, Pearson's correlation, and stepwise regression analysis using the program of SPSS. The findings of the study were as follows. (1) there was a difference between the average score of subcategory and the total score of leadership according to the gender of preschooler and mother's employment and her educational background. However, there was no difference from the birth order of preschooler. (2) A correlation was not found between mother's discipline style and preschooler's leadership, but the significant negative correlation showed up between preschooler's emotional regulation strategies and preschooler's leadership. (3) The leadership of preschoolers who use positive coping strategies of a sub-area of emotional regulation strategies appeared strong. And the leadership appeared low with a boy who uses avoidant & supportive strategies, supportive strategies, aggressive strategies and venting strategies more often. Furthermore, the model of explanatory adequacy (R2) of some independent variables from the average scores of subcategory and the total score of leadership was confirmed to be the statistically significant explanatory model.

  • Soybean (Glycine max (L.) Merr.) is an important crop for protein, oil, carbohydrates, isoflavones, and many other nutrients to humans and animals. But, antinutritional factors in the raw mature soybean are exist. Raffinose and stachyose are main antinutritional factors in soybean seed. Both raffinose and stachyose are carbohydrates, belonging to the raffinose family of oligosaccharides (RFOs). RFOs are not readily digested in humans and cause flatulence or diarrhea. The objective of this research is to obtain the information on raffinose and stachyose content according to genotype and environment. A total of twenty two soybean genotypes (11 cultivars, 3 germplasms and 8 breeding lines) were selected. Each genotype was grown in the field for two years with two replications and harvested in bulk at natural maturity for two years. Content of raffinose and stachyose was detected by HPLC. The raffinose content (g/kg) of 22 genotypes was $2.68{\pm}0.21-5.87{\pm}2.43$ in year 1 and was $3.24{\pm}0.37-9.05{\pm}0.16$ in year 2. The stachyose content (g/kg) was $4.23{\pm}0.98-27.68{\pm}9.90$ at year 1 and was $5.11{\pm}1.09-25.32{\pm}0.35$ in year 2. Genotype and environment have highly significant effects on raffinose and stachyose content. Three genotypes (Da-7, 116-13, and RS-78) have low stachyose content at 5% significant level in two years. A positive correlation ($R^2=0.1985^*$) between raffinose and stachyose was observed in year 2. These informations are valuable in soybean genetics and breeding program related with raffinose and stachyose content.

  • The antioxidant activity and the qualitative analysis of Acanthopanax sessiliflorum Seeman were studied by partially purified extract using various methods: extraction by using ethanol solutions and temperatures, and absorption to Diaion HP20 column chromatography using 10%, 20%, 40%, 60% ethanol solutions. Major constituents, chlorogenic acid, caffeic acid, eleutheroside E, was determinated by HPLC method in Acanthopanax sessiliflorum S. 10% and 20% ethanol solutions contain chlorogenic acid (3.020$\pm$0.080%, 20.500$\pm$1.150%, respectively). 40% ethanol solution contains caffeic acid and eleutheroside E (12.270$\pm$0.360%, 1.670$\pm$0.140%, respectively). Diaion HP20 fractions (10%, 20%, 40%, 60% ethanol solutions) showed the scavenging activity of radicals and reactive oxygen species with the $IC_{50}$ values of $81.534{\pm}0.992{\mu}g/ml$, $1.748{\pm}0.098{\mu}g/ml$, $11.487{\pm}1.768{\mu}g/ml$, $21.960{\pm}0.547{\mu}g/ml$ against 1,1-diphenyl-2-picrylhydrazly radical and $1713.548{\pm}34.565{\mu}g/ml$, $131.419{\pm}2.235{\mu}g/ml$, $200.681{\pm}2.444{\mu}g/ml$, $757.897{\pm}6.868{\mu}g/ml$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. Especially, 20% and 40% ethanol fractions showed more antioxidant activity than dl-$\alpha$-tocopherol. These results suggest that Acanthopanax sessiliflorum S. extract and Diaion HP20 fractions may be useful as a potential source of nutraceutical and cosmetic products.

  • Objectives: The purpose of this study was to examine whether Temporomandibular Joint Balance Appliance-Golf (TBA-G) can improve postural control ability of healthy adults. Methods: Twenty participants (10 male, 10 female) aged 20 to 39 years were involved. Postural control ability of all participants was assessed before and after applying TBA-G with Balance $Master^{(R)}$ system. Modified clinical test sensory interaction on balance (mCTSIB), unilateral stance, weight bearing and rhythmic weight shift were used to evaluate postural control ability. Results: After applying TBA-G, mCTSIB on a firm plate with eyes open increased from 0.2 to 0.23 (p<0.05) but directional control was improved in slow and moderate velocity of front/back rhythmic weight shift test (P<0.05). In two cases with postural imbalance, most of the postural control measures improved after applying TBA-G. Conclusions: The results suggest that TBA-G could improve balance control ability. A larger controlled trial is needed to determine more accurately the effect of TBA-G on balance control ability.

  • The roots of Brassica rapa ssp. were extracted with 95% aqueous ethanol and the concentrated extracts were partitioned using ethyl acetate (EtOAc), n-butyl alcohol and $H_2O$, successively. From the EtOAc fraction, five flavonoids were isolated through repeated silica gel and octadecyl silica gel (ODS) column chromatography (c.c.). Based on NMR, mass spectrometry (MS) and IR spectroscopic data, the chemical structures of the compounds were determined to be licochalcone A (1), 4,4'-dihydroxy-3'-methoxychalcone (2), liquirtigenin (3), liquiritin (4), and isoliquiritin (5). This is the first report of these compounds isolated from the root of this plant.

  • Objective This study was to identify the risk factors for cytological progression in women with atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL). Methods We analyzed data from women infected with the human papillomavirus (HPV) who participated in the Korean HPV cohort study. The cohort recruited women aged 20-60 years with abnormal cervical cytology (ASC-US or LSIL) from April 2010. All women were followed-up at every 6-month intervals with cervical cytology and HPV DNA testing. Results Of the 1,158 women included, 654 (56.5%) and 504 (43.5%) women showed ASC-US and LSIL, respectively. At the time of enrollment, 143 women tested positive for HPV 16 (85 single and 58 multiple infections). Cervical cytology performed in the HPV 16-positive women showed progression in 27%, no change in 23%, and regression in 50% of the women at the six-month follow-up. The progression rate associated with HPV 16 infection was higher than that with infection caused by other HPV types (relative risk [RR], 1.75; 95% confidence interval [CI], 1.08-2.84; P=0.028). The cytological progression rate in women with persistent HPV 16 infection was higher than that in women with incidental or cleared infections (P<0.001). Logistic regression analysis showed a significant relationship between cigarette smoking and cytological progression (RR, 4.15; 95% CI, 1.01-17.00). Conclusion The cytological progression rate in HPV 16-positive women with ASC-US or LSIL is higher than that in women infected with other HPV types. Additionally, cigarette smoking may play a role in cytological progression.
