  • The mother's obesity-related stress and it's association with obesity, food intake, and physical activity in both mothers and their children were determined. Based on self-reports from 470 mothers, obesity stress of mothers were scored by using a five-point Likert scale; only low and high stress scores were used in this study. The perceptions of mothers' weights and their children's weights, mothers' Body Mass Indices (BMI), and preschoolers' Weight-Length Indices (WLI)(%) were also determined. The obesity stress of mothers was significantly associated with the mothers' BMI (high stress: $23.5{\pm}2.4$ vs. low stress: $19.6{\pm}1.7$, p<0.05), but not with their children's obesity. Mothers with a high obesity stress reported a higher percentage of family history of obesity (62.1% vs. 38.3%, p<0.001) than mothers with low obesity stress. Compared to mothers with low obesity stress, mothers with high stress had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions for their children's weights. Almost 54.5% of mothers with high stress reported watching television 2 or more extra hours per day, compared with 32.2% of mothers with low stress (p<0.05). More children of mothers with high stress had long hours of daily TV viewing than children of mothers with low stress (36.0% vs. 15.3%, $X^2=10.491$, p<0.05). Mothers with high stress reported lower intake of protein-rich foods (p=0.01) and vegetables (p=0.039), but a higher intake of snacks (p=0.009), compared to mothers with low stress. More children of mothers with high stress reported eating high fat snacks or high sugar snacks everyday, but this was not statistically significant. In conclusion, high obesity stress in mothers were greatly associated with their BMI and their inactive life style, including long TV viewing hours per day and unbalanced food intakes, which can lead their children becoming inactive and obese. Special attention is recommended for overstressed mothers and their children, especially those who enjoy long hours of TV viewing.

  • The effect of physiological factors of beet armyworm, Spodoptera exigua (Hubner), on esterase variation was analyzed by comparing electrophoretic esterase isozymes. Each esterase isozyme was also characterized by substrate and inhibitor specificities. A total of 28 esterase isozymes were separated on 10% nondenaturing polycarylamide gel electrophoresis (PAGE). These isozymes were denoted from El to E28 according to cathodal migration distances. There was a variation in esterase isozymes among developmental stages. Larvae and pupae had more isozymes than did adults. Eggs had only eight isozymes. The isozymes of El and E2 were specific only in the first instar larvae. Esterases also showed variation according to different tissues. More kinds of esterase isozymes were found in epidermis and gut tissues than in hemolymph and fat body. Some isozymes were specific in epidermis (from El to E6), gut (E10, El 1, E25, E26, and E27), and hemolymph (E18). Among 10 naphthyl esters, a-naphthyl propionate was the most reactive substrate to the esterase isozymes. The isozymes were classified into cholinesterases (El0 and E24), arylesterases (E4, E9, E17, E19, E21, and E23), and carboxylesterases (the others) on the basis of inhibition by the esterase inhibitors-eserine, dichlorovos, moncrotophos, and paraoxon.

  • Objectives : This study was designed to investigate effects of the combination with Korean Red Ginseng (Panax ginseng C.A. Meyer), Gastrodia Rhizoma (Gastrodia elata Blume) and Polygoni Multiflori Radix (Polygonum multiflorum Thunberg) on metabolic disorders including cholesterol and erectile dysfunction in hyperlipidemia rats.Methods : Animals were divided into six groups; Control with normal diet, high fat/cholesterol-diet (HFCD), fluvastatin, Korean Red Ginseng treated (KRG), and the combination treated (Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori Radix; 1:1:1 for KGP1 and 2:1:1 for KGP2). The experimental groups initially received HFCD for 10 weeks and then treated orally with fluvastatin, KRG, KGP1 and KGP2 during the final 6 weeks. Erectile function was determined by the measurements of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve.Results : KGP2 decreased the level of total cholesterol and LDL cholesterol in the sera of HFCD rats without no changes of body weights. KRG, KGP1 and KGP2 decreased the level of C-reactive protein (CRP) levels except of fluvastatin, synthetic HMG-CoA reductase inhibitor. KRG, KGP1 and KGP2 significantly increased the ICP, ICP/MAP ratio, area under the curve (AUC) compared with those of normal rat. Morphometric analyses showed that KRG, KGP1 and KGP2 increased the volume of smooth muscle and the regular arrangement of collagen fibers in corpus cavernosum of HFCD rats. The penile expression of eNOS was increased by KRG, KGP1 and KGP2.Conclusions : Based on these results, we suggest that the combination with Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori may improve hyperlipidemia through regulating the lipid profiles and erectile dysfunction in rats.

  • Mesenchymal stem cells(MSCs) have been though to be multipotent cells that can replicate that have the potential to differentiate into lineages of mesenchymal tissue including the bone, cartilage, fat, tendon, muscle, and marrow stroma. Especially, scaffolds to support cell-based tissue engineering are critical determinants of clinical efforts to regenerate and repair the body. Selection of a matrix carrier imvolves consideration of the matrix's role as a scaffold for physical support and host tissue integration as well as its ability to support of synergize the osteoinductive program of the implanted mesenchymal stem cell. The aim of this study is to evaluate the effect of autobone and Bio-$Oss^{(R)}$ to adherent mesenchymal stem cells as scaffolds on sinus augmentation with fibrin glue mixture in a rabbit model. 16 New Zealand White rabbits were divided randomly into 4 groups based on their time of sacrifice(1, 2, 4 and 8 weeks). First, mesenchymal stem cells were isolated from iliac crest marrow of rabbits and expanded in vitro. Cell culture was performed in accordance with the technique described by Tsutsumi et al. In the present study, the animals were sacrificed at 1, 2, 4 and 8 weeks after transplantation, and the bone formation ability of each sides was evaluated clinically, radiologically, histologically and histomorphologically. According to the histological observations, autobone scaffolds group showed integrated graft bone with host bone from sinus wall. At 2 and 4 weeks, it showed active newly formed bone and neovascularization. At 8 weeks, lamellae bone was observed in sinus graft material area. Radiologically, autobone with stem cell showed more radiopaque than Bio-$Oss^{(R)}$ scaffolds group. there were significant differences in bone volume between 4 and 8 weeks(p<0.05).

  • The purpose of this study was to obtain basic data of nutrition education for obese children and to examine food habits, food behaviors, and nutrition knowledge. A convenience sample of 84(male:62, female:22) obese children was selected from "98 Children Nutrition Camp". The survey design employed a structured questionnaire. The results of this study were summarized as follows. 1. The percentage of the subjects who overestimated their body weight was higher in female compared to male. Only 35.9% of highly-obese subjects considered them as 'very fat'. The experience of weight control was higher in female than in male, and it was also higher moderately- or highly-obese subjects compared to mildly obese. 2. 64.3% of subjects reported that they regularly eat breakfast. The percentage of the subjects who indicated that they eat at regular meal time or they eat very irregularly was highest in the highly-obese subjects. 3. 34.5% of subjects reported that they eat very fast. The eating speed was slower in female compared to male, and in obese subjects. 55.4% of subjects reported that didn't eating out. 4. 80.9% of subjects had snacks, and most of them had snack between lunch and dinner. The reason the subjects eat snack was hunger. The most favorite snack was cookies. 5. The most preferred and distasteful food was meats(32.1%) and vegetables(67.1%), respectively. 6. The score of food behaviors was relatively low in most subjects. 7. The level of nutrition knowledge was in order of fair(83.1%), poor(9.6%), excellent(7.3%), and was higher in male compared to female. Consequently the results of this study showed to disagreement among food habits, food behaviors and nutrition knowledge, and feel keenly the necessity of education connecting of these. This education had to be practical education to change food behaviors.

  • Barley flakes were developed by extrusion cooking using broken kernels, by-products of the barley pearling process. Broken kernels from both non-waxy and waxy barley broken kernels were sufficiently gelatinized at the barrel temperature of over $100^{\circ}C$ and the moisture content of broken kernels of over 35%. Cutting and flaking roll separating properties of pellets prepared from non-waxy barley broken kernels were better than those of waxy barley broken kernels. Characteristics of pellets prepared by extrusion cooking in different mixing ratios of non-waxy and waxy barley broken kernels were investigated. As the mixing ratio of waxy barley broken kernels increased, RVA peak viscosity, apparent viscosity, and yield stress of prepared pellets decreased, while flow behavior index increased. As the mixing ratio of waxy barley broken kernels increased, compressive strength and bulk density of deep-fat fried flakes drastically decreased, and the size of air cells on cross-section increased, and thickness of cell-constituting bodies decreased. Sensory evaluation results showed that acceptability for texture and taste of flakes inclosed as the mixing ratio of waxy barley broken kernels increased, and optimum mixing level of waxy barley broken kernels appeared to be 30-40%.

  • It has already been reported that short neuropeptide F (sNPF) stimulates feeding behaviors in a wide variety of insect species. In the present study, we cloned cDNA, encoding a sNPF receptor homologue from a silkworm, Bombyx mori, named BsNPF-R. The amino acid sequence of BsNPF-R was compared with those of sNPF-R thus far reported, which is shared with humans (36%), mice (34%), zebrafish (35%), and fruit flies (51%), respectively. A BsNPF-R protein’s mass was theoretically estimated to be 42,731 Da and it is a putative plasma membrane-penetrating protein. The mRNA expression of BsNPF-R was tested; the results showed that a strong expression was detected at the midgut, post-silk gland, Malpighian, and testis; however, a weak expression was at the fat body, hemocyte, and ovary. In addition, the synthesized sNPF of a silkworm regulated the BsNPF-R mRNA expression through the cell-based functional analysis.

  • The TAZ activator 2-butyl-5-methyl-6-(pyridine-3-yl)-3-[2'-(1H-tetrazole-5-yl)-biphenyl-4-ylmethyl]-3H-imidazo[4,5-b]pyridine] (TM-25659) inhibits adipocyte differentiation by interacting with peroxisome proliferator-activated receptor gamma. 1 TM-25659 was previously shown to decrease weight gain in a high fat (HF) diet-induced obesity (DIO) mouse model. However, the fundamental mechanisms underlying the effects of TM-25659 remain unknown. Therefore, we investigated the effects of TM-25659 on skeletal muscle functions in C2 myotubes and C57BL/6J mice. We studied the molecular mechanisms underlying the contribution of TM-25659 to palmitate (PA)-induced insulin resistance in C2 myotubes. TM-25659 improved PA-induced insulin resistance and inflammation in C2 myotubes. In addition, TM-25659 increased FGF21 mRNA expression, protein levels, and FGF21 secretion in C2 myotubes via activation of GCN2 pathways (GCN2-$phosphoelF2{\alpha}$-ATF4 and FGF21). This beneficial effect of TM-25659 was diminished by FGF21 siRNA. C57BL/6J mice were fed a HF diet for 30 weeks. The HF-diet group was randomly divided into two groups for the next 14 days: the HF-diet and HF-diet + TM-25659 groups. The HF diet + TM-25659-treated mice showed improvements in their fasting blood glucose levels, insulin sensitivity, insulin-stimulated Akt phosphorylation, and inflammation, but neither body weight nor food intake was affected. The HF diet + TM-25659-treated mice also exhibited increased expression of both FGF21 mRNA and protein. These data indicate that TM-25659 may be beneficial for treating insulin resistance by inducing FGF21 in models of PA-induced insulin resistance and HF diet-induced insulin resistance.

  • The present study was to elucidate such a relationship by comparing the coronary risk factors with and without fatty liver adjusted for age and/or BMI. Study subjects were 665 women of 30 years and over, who underwent health package check-up at the health promotion center of an university hospital from July, 2009 to June, 2010. As a results, the prevalence rates of fatty liver of study subjects were 11.6%, and the rates were significantly higher in older age group, in the group of higher level of BMI. The group of subjects with fatty liver had significantly lower mean HDL-cholesterol and higher levels of body fat rate, TG, TC, LDL-cholesterol, FBS and ALT, then those parameters in subjects without fatty liver, even after adjustment for age and/or BMI. In age and BMI adjusted logistic regressions, The odds ratio of fatty liver was increased significantly as there is an increase in the abnormal group with TG, TC, LDL-C and ALT.

  • The purpose of this study was to examine the blood pressure, serum lipid levels and obesity indices according to smoking status, and the effects of smoking cessation on blood pressure, serum lipid and obesity indices. The 2,230 male workers aged 30-59 years were observed the age, smoking status, SBP, DBP, TC, TG, HDL-C, LDL-C, AI, BMI, body fat rate and waist circumference, from April to July, 2011. As a results, the mean score of SBP, DBP, TC, TG and BMI were significantly higher in smoking group than non-smoking group, but HDL-C were significantly lower in smoking group than non-smoking group, the distribution of hypertension was significantly higher in smoking group than non-smoking group. The abnormal levels of TC, TG and HDL-C were significantly higher in smoking group than non-smoking group, and the distribution of obesity was significantly higher in smoking group than non-smoking group. Age adjusted odds ratio(ORs) was significantly increase in smoking group than non-smoking group: hypertension(3.59 times), hypercholesteremia (1.49 times), hyperlipidemia(1.81 times), low HDL-cholesteremia(1.58 times), high level of atherogenic index(1.27 times). Above results suggested that the smoking related with blood pressure and serum lipid levels.
