As a microwave near field probe for near field scanning optical microscope(NSOM) system, H-shaped(ridge type) small aperture is proposed and its performances from the viewpoints of the transmission efficiency(transmission cross section) and spatial confinement(beam spot size) are compared with those of the previous narrow rectangular aperture type. While the transmission efficiencies are comparable to each other for the two structures, the transmitted beam spot size for the proposed H-shaped aperture is much smaller than that for the previous rectangular aperture. This strong point of the H-shaped aperture is expected to significantly improve near-field optical applications such as optical data storage, nanolithography and nanomicroscopy. It is also observed that the transmission efficiency can be improved if the coupling aperture is implemented in the type of the transmission cavity.

Objectives: The purpose of the study was to analyze the association between dyslipidemia and periodontitis in Korean adults aged 30 and older. Methods: We examined 3,992 subjects participating in the 2015 Korean National Health and Nutrition Examination Survey. Periodontal status was evaluated using the community periodontal index (CPI). People with 3 or 4 CPI codes were classified as the periodontitis group. For statistical analyses, chi-square test and logistic multiple regression were used. Results: The prevalence of periodontitis was higher in men, people aged 70 and over, people whose income status was among the lower 25%, and people whose educational level was high school or lower (p<0.001). The prevalence of periodontitis was higher in people who brushed their teeth twice or less, those who did not use interdental cleaning devices, those who did not have a dental checkup in the last 12 months, and those who had not drunk or smoked (p<0.05). The prevalence of periodontitis was increased with individuals whose BMI was ≥25 kg/㎡, those whose glycated hemoglobin was ≥6.5%, and whose lipid levels were higher or lower than the normal range. In the logistic regression model, an increase in triglyceride was found to increase the prevalence of periodontitis (p<0.05). Conclusions: The study suggests that dyslipidemia, especially hypertriglyceridemia, is a predictor of periodontitis.

The effects of dried green tea leaf powders on serum lipid concentrations were evaluated in rats. Sixty male Sprague-Dawley rats weighing $100{\pm}10g$ were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Normal fat diet and normal and high fat diets with 1% dried green tealeaf powders. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by dried green tea leaf powders groups. The concentrations of serum triglyceride in rats fed the dried green tea leaf powders were lower than those in other groups. The concentrations of total cholesterol in green tea leaf powders the were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the dried leaf powders green tea were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the dried green tea leaf powders groups were tended to be lower than those of other groups. GPT and GOT were decreased in dried green tea leaf powders groups and than in the high fat group. LDHase was lower in the dried green tea leaf powders groups than in the high fat group. These results suggest that dried leaf powders green tea groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

This study was performed to study the effects of Gastrodiae rhizoma on lipid concentration of serum and liver in rats fed high fat diet. Male Sprague-Dawley rat were randomly assigned to 5 groups such as basal diet only(BDG), high fat diet(HFG) and high fat diet with 5% processed Gastrodiae rhizoma(GRL), high fat diet with 10% processed Gastrodiae rhizoma(GRM), high fat diet with 15% processed Gastrodiae rhizoma(GRH) supply each of the experimental diets for 6 weeks. Food intake was significantly decreased by both high fat intake and high fat with Gastrodiae rhizoma intake compared with basal diet intake but weight gain was not significantly different from each groups. Liver weights were significantly lowered by Gastrodiae rhizoma intake compared with high fat intake. In the serum, total cholesterol was not significantly different with each groups, but triglyceride level was significantly lowered by Gastrodiae rhizoma intake as compared with control. In the liver, lipid levels inceased with the Gastrodiae rhizoma intake, but total cholesterol and triglyceride levels were not significantly different with control. These results showed that dietary Gastrodiae rhizoma as supplementary food may decrease triglyceride in the serum.

This study, analyzed the general and minerals composition of kamut and investigated its effect on blood components in mice fed a high fat diet. The content of each general component of kamut was as follows: $11.02{\pm}0.75%$ water, $13.16{\pm}1.28%$ crude protein, $1.85{\pm}0.19%$ crude fat, and $1.97{\pm}0.13%$ ash. The leptin level was the highest in the HF group($30.00{\pm}0.00ng/mL$) when compared to the control group. There was a significant decrease of $23.65{\pm}5.54ng/mL$ in the HFK group when compared to the HF group (p<0.05). The blood LDL-cholesterol concentration was the lowest in the control group at $10.00{\pm}2.00mg/dL$. The level was highest in the HF group at $28.00{\pm}0.00mg/dL$ when compared with the other groups (p<0.05). The aspartate transaminase (AST) level was significantly higher in the HFK group ($179.33{\pm}173.88U/L$) than in the control ($61.00{\pm}12.73U/L$) and HF groups ($132.00{\pm}0.00U/L$). According to the results of this study, the consumption of kamut lowers the blood LDL-cholesterol level more than the consumption of wheat flour. Additionally, kamut contains antioxidant substances such as selenium and zinc, which are thought to contribute to vascular health and thus aid in maintaining good health. Therefore, it is necessary to develop a variety of health foods using kamut; it should be used as a functional food for the maintenance of good health.

This study was conducted to investigate anti-oxidative and inflammatory inhibition effects of green tea and dietary fiber mixture on liver of high fat diet-induced obese rats. 21 male rats were divided into 3 dietary groups and control group (A), high fat diet-induced group (B), and high fat (HF) diet-induced + EQ diet-$S^{(R)}$ diet group (C). Immunoblotting and RT-PCR analysis revealed protein expression, and anti-oxidant analysis revealed MDA (malondialdehyde), GSH (glutathione), and free DPPH radical. As a results, Body weight and food consumption were not significantly different between groups. The levels of MDA and GSH were lower in HF + $EQS^{(R)}$ group than in HF group. Also, the $EQS^{(R)}$ demonstrated to be more effective than HF group for a DPPH radicals scavenging activities. In addition, protein and mRNA level of TNF-$\alpha$ in HF + $EQS^{(R)}$ group showed relatively more potent pro-inflammatory activity inhibition compared to HF group. These results suggest that green tea mixture (EQ diet-$S^{(R)}$) provide positive effects on anti-oxidative and inflammatory inhibition effects on obese animal model or obesity related diseases.

For lactic acid fermentation of chestnut broth,10 strains of bacteria were isolated from human feces and commercial yogurt,6 of which were identified to be Bifidobacterium and the rest isolated from Acidities of the chestnut broths fermented by these strains were lower than yogurt, but more than two times higher than yogurts made from seeds or vegetables including soy milk. To stimulate acidity of the fermented broths, addition of yeast extract and tryptone peptone were the most effective at the concentration of 0.2 and 0.4%, respectively, while glucose addition above 0.5% up to 8% did not increased the acid production except a few strains of Lactoba- Cillus. Among the tested fruits and vegetables, carrot juice supplementation was the most effective in acid produc- tion by most of the tested strains. Saccharification of chestnut broth by hydrolyzing process greatly increased the acid production at 25% of cooked chestnut. However, compared to the results from the 8% of unhydrolyzed chest- nut, the net increase in acid production by hydrolysis was not much stimulative.
