BACKGROUND/OBJECTIVES: Numerous researches have studied the association between sugar intake and obesity of children in many countries. This study was undertaken to investigate the association between beverage intake and obesity of children by reviewing a database for total sugar contents established in all foods and presented in a nutrition survey by the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: Data of 1,520 children aged 6-11 years in the 6th KNHANES (2013-2015) were analyzed for this study. A database for total sugar intake comprises the total sugar contents of all foods included in the results of a nutrition survey using the 24-hour recall method of 6th KNHANES. Beverages were categorized into carbonated beverages, fruit & vegetable drinks, other drinks, tea, and coffee. RESULTS: The average daily beverage intake of all children was 131.75 g/day, and the average daily total sugar intake in beverages was 13.76 g/day. Carbonated beverages had the highest intake rate (58.85 g/day) and also ranked highest for sugar intake (6.36 g/day). After adjusting for confounding variables, the odds ratio for obesity in children with beverage intake of ${\geq}200mL/day$ significantly increased by 1.83 times (95% CI, 1.11-3.00) as compared to children with beverage intake of < 200 mL/day. Also, a significant increase was observed in the odds ratio for obesity in total children (2.41 times; 95% CI, 1.35-4.33) and boys (3.15 times; 95% CI, 1.53-6.49) with carbonated beverage intake of ${\geq}200mL/day$ when compared with children who consumed < 200 mL/day. CONCLUSION: A positive association is observed between beverage intake and obesity in Korean children. In particular, an intake of carbonated beverages has a positive correlation with childhood obesity in boys. This study can therefore be used as scientific evidence for reducing sugar, and for the continuous management and research on beverages.

The purpose of this study was to determine the characteristics of infants' temperaments and eating behaviors, mothers' eating behaviors and feeding practices in poor eating infants. The participants were 80 infants of 12-24 months (27 poor eaters and 53 matched normal controls) from a hospital and a public health center. Mothers were questioned about their eating behaviors and feeding practices, and infants' temperaments, eating behaviors, and nutrient intakes by one day food recall. Subjects were divided by mean nutrient adequacy ratio (MAR, < 0.75; poor eater). Intakes of Ca, P, Fe, Zn, thiamin, riboflavin, niacin, vitamin C, E, folate were below 75% RDA in poor eaters, whereas protein, thiamin, riboflavin, vitamin B$_6$, C, folate exceeded 125% RDA in good eaters. Rhythmicity of infants' temperaments and eating behaviors, restriction of mothers' eating behaviors and feeding practices were significantly lower, whereas activity levels of infants' temperaments were higher than good eaters. In multiple logistic regression model of poor eaters, activity of infants' temperaments (T, OR: 1.19, CI: 1.05 - 1.35) and attention spans of infants' eating behaviors (A, OR: 1.18, CI: 1.03 - 1.35) were significantly positive, whereas rhythmicity of infants' eating behaviors (R, OR: 0.79, CI: 0.61-0.94) was significantly negative [E (the legit) : -6.8644+0.1712$\times$T-0.2337$\times$R+0.1641$\times$A]. Our findings suggest that examination of eating behaviors, feeding practices, and temperaments will help target interventions to improve infants' food intakes, and these variables should be examined at the time of nutrition counseling.

Purpose: The clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies. Methods: The study included children <10 years of age with signs and symptoms indicative of immediate-type food allergies. Serum total IgE level was measured, and ImmunoCAP analysis for food allergens was performed. Results: The mean age of the study subjects was $1.6{\pm}1.6$ years (75 boys and 51 girls). Thirty-eight children (30.2%) were monosensitized and 88 children (69.8%) were polysensitized. Multivariate logistic regression analysis showed that the development of polysensitization to common food allergens was positively associated with a parental history of allergic rhinitis (adjusted odds ratio [aOR], 6.28; 95% confidence interval [CI], 1.78-22.13; P=0.004), season of birth (summer/fall) (aOR, 3.10; 95% CI, 1.10-8.79; P=0.033), and exclusive breastfeeding in the first 6 months of age (aOR, 3.51; 95% CI, 1.20-10.25; P=0.022). Conclusion: We found significant clinical differences between children with monosensitization and those with polysensitization to common food allergens and identified risk factors for the development of polysensitization in young children with immediate-type food allergies. Clinicians should consider these clinical risk factors when evaluating, counseling, treating, and monitoring young children with food allergies.

The effects of Aralia canescens and Phellodendron amurense(AP) extracts on the experimental diabetes in ICR mice were investigated. 96male ICR mice were induced diabetes mellitus by intrape-ritoneal streptozotocin injection(75mg/kg B.W.) and divided into two injection groups which are 5 day injection and 10 day injection group. Then, each injection group was subdivided into 8 groups of 6 animals repspectively. CIC served as control and CI1, CI2 and CI3 were treated with 50, 150, 250mg/kg B.W. of AP extracts powder in 0.9% NaCl solution. Animals of groups DIC, DI1, DI2 and DI3 were strepto-zotocin-induced diabetes. DIC served as diabetic control and the rest groups received 50, 150, 250mg/kg B.W of AP extracts powder in saline solution respectively. The body weight, liver and kiney weight changes and blood levels of glucose, cholesterol and triglyceride were measured. Thiobarbituric acid reactive substance(TBARS), and glutathione reductase(GR) and glutathione peroxidase(GPx) activities were also measured for determining antioxidant effects. AP extracts increased the body weight in diabetic groups. The liver and kidney weight/100g B.W. in DIC group were greater than those of normal ICR group but after AP extracts injection, liver and kidney weight were decreased significantly. These effects were more efficient at 10 days injection group. The total, LDL, VLDL cholesterol and triglyceride levels were significantly higher in DIC group and the extent of decrement responded to AP injection dose. The contents of TBARS and antioxidant enzyme activities were relatively decreased after AP extracts injection. These results suggest that the intraperitoneally administered AP extracts may have not only hypoglycemic effect but act as antioxidants by reducing lipid peroxidation.

Objective: We investigated arthralgia and myalgia associated with the use of oral bisphosphonate (BP) by conducting a survey of patient. Methods: The pharmacists conducted a survey between 1 Oct 2019 and 30 Sep 2020 among patients who were dispensed BP in community pharmacies to assess their demographic and medical characteristics, and their experiences with, and process for pain. Logistic regression analyses were performed to find the risk factors associated with the pain, and the odds ratios (OR) and 95% confidence intervals (CI) were determined. Results: A total of 160 patients who used BP participated in the survey (74 [46.3%] used risedronate; 61 [38.1%] used alendronate; 23 [14.4%] used ibandronate), and 20 (12.5%) of them experienced pain. Significant statistical differences of the characteristics between patients who experienced pain or not were observed regarding menopause, and parity. Compared with women who had one or two parity, women who had more than three parity were associated with the decreased risk of pain (OR, 0.24; 95% CI, 0.04-0.98). Moreover, steady exercise was associated with the decreased risk of pain compared to less exercise (OR, 0.37; 95% CI, 0.14-0.98). Conclusion: Our findings suggest that the risk of pain in BP-treated patients might be different regarding the different ingredients of BP, and dosing frequency. This survey highlights a need for a further safety research to understand the factors influencing the pain associated with the BP treatment.

Contents of proline and chloride in halophytes were $80-1700\;{\mu}g/gfw$ and 0.13-0.45 mM/gfw respectively. The content of proline was inversely proportional to that of chloride. Rhizomes of Phargmites communis Trin, a halophyte, were grown in non-saline medium and then taken to saline treatment for one or two weeks. Growth of P. communis was inhibited when salinized with 0.25M NaCl. Total nitrogen decreased and alcohol soluble nitrogen and proline increased when growth was retarded. The quantity of Fraction 1 protein decreased at 0.25M NaCl treatment. The accumulation of proline at high concentration in P. communis suggested that it might play a role in osmotic adjustment.

Recently, indirect evidences suggest that Na-Ca exchange mechanism is involved in bone resorption. To study this suggestion, effects of several drugs which increase the intracellular sodium concentration by different mechanisms on the PTH-induced bone resorption were analysed employing organ culture. Ulnae and radii were removed from 19-day fetal rats, prelabelled by subcutaneous injection of $200{\mu}\;Ci^{45}CaC1_2$ on the 17th day of gestation, and then explanted on the membrane filters in organ culture dishes. For studying the effects of amiloride, ouabain, monensin, and veratridine on the PTH-induced bone resorption, control group was cultured in BGJb media containing PTH (0.4U/ml) while experimental group was cultured in BGJb media containing PTH and drugs. The effects of drugs on the PTH-induced bone resorption were observed by the ratios of $\%-release$ of $^{45}Ca$ between paired control and experimental groups. The results were as follows: 1. $^{45}Ca$ release was significantly increased by PTH (0.4U/ml) at 48 and 72 hours of culture. 2. Amiloride, at concentration of $500{\mu}M$, significantly inhibited the PTH-induced bone resorption after 48 and 72 hours of culture. 3. Ouabain, at concentration of 0.1 mM, presented significant inhibition of PTH-induced bone resorption after 48 and 72 hours of culture, and at 0.5mM and 1mM, presented significant inhibition of PTH-induced bone resorption after 72 hours of culture. 4. Monensin, at concentration of 500nM, significantly inhibited PTH-induced bone resorption after 72 hours of culture. 5. Veratridine, at concentration of 0.5mM, presented significant inhibition of PTH-induced bone resorption after 48 and 72 hours of culture, and at 1mM, presented significant inhibition of PTH-induced bone resorption after 72 hours of culture. Taken altogether, these results suggest that Na-Ca exchange mechanism play a role in PTH-induced bone resolution.

Processible polyaniline (PAM) dispersions consisting of polyaniline micro-particles, cyclohexanone, and a polymeric surfactant were prepared in a micro-milling machine with various mixing conditions. The electrochemical properties of the dispersion film coated on Pt electrode were investigated by cyclic voltammetry (CV). The electrochemistry of the PAM dispersion coatings was basically similar to a pure PAM coating based on the results of CV. The results of polarization measurements and open circuit potential measurements carried out in $3\;wt.\%$ NaCI solution showed increase in corrosion potential when the PANI dispersion coatings applied on steel surface. Variation of open circuit potential $(OCP,\;V_{OC})$ of the dispersion coating/steel electrodes was observed, which differed with milling conditions. The results demonstrated practical use of the conducting polymer dispersion as a coating material for corrosion prevention of steel.

The promoter regions from chromosomal DNA of Bacillus sp. SSA3 which is responsible for fermentation of Korean traditional soy sauce, were cloned for construction of expression vector of Bacills sp. SSA3. Recombinant plasmids were constructed by insertion of HindIIl-cleaved Bacillus sp. SSA3 chromosomal DNA fragments in front of the CAT gene of pGR71 plasmid and B-galactosidase gene of pUC18 plasmid. 6 recombinant plasmids were isolated from chloramphenicol resistant E. coli JM109 clones. All these plasmids were found to have promoter activity in Bacills sp. SSA3 and E. coli JM109. When these 6 clones of Bacills sp. SSA3 were cultivated in LB agar medium supplemented with 10% NaCI. fused CAT gene expression of 4 clones was significantly decreased in common. But the others were poorly inhibited.
