There are a few studies that reported the association of sleep duration with calorie intake and energy expenditure. Using cross-sectional data from a population-based prospective study, we evaluated the association of sleep duration with indicators of obesity including body mass index and waist circumference, calorie intake and its proportion of macronutrients, and physical activity. The study subjects were 4,226 male and female adults, who were aged 40 to 69 years and were free of diagnosed cardiovascular disease, diabetes mellitus, and dyslipidemia at baseline. Robust regression analysis was used to analyze associations. The study found that sleep duration is inversely associated with waist circumference, calorie intake, and percent of calories from fat intake and is positively associated with percent of calories from carbohydrate intake and physical activity. The inverse association between sleep duration and waist circumference was stronger among men than among women. The inverse association between sleep duration and calorie intake was stronger among women than among men and such association was also stronger among obese persons than those with a normal body mass index. The positive association between sleep duration and physical activity was strongly demonstrated regardless of sex or obesity. Physical activity is positively associated with sleep duration independent of potential confounding factors including age, sex, income, occupation, marital status, education, smoking status, waist circumference, calorie and macronutrient intake, and alcohol intake.

Due to poor nutrition and abnormal energy metabolism, cancer patients typically experience the loss of muscle mass. Although the diabetic conditions or dyslipidemia have been reported as a causal link of cancer but the consequence of such conditions in relation to gain or loss of skeletal muscle mass in cancer patients has not been well documented. The purpose of this study was to investigate the relationship of lean body mass and systemic parameters related to lipid metabolism in non-diabetic cancer patients using data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008-2011. As results the level of serum total cholesterol (total-C) was negatively associated with both total lean body mass and appendicular lean body mass in cancer patients after adjustment for sex, physical activity, energy intake and comorbidity. The associations between consumption of dietary factors (energy, carbohydrate, protein and fat) and lean body mass were disappeared after adjusting comorbidities of cancer patients. Multivariate-adjusted linear regression analysis by quartiles of serum total-C showed that higher quartile group of total-C had significantly lower percent of lean body mass than reference group in cancer patients. The data indicate that serum lipid status can be the potential estimate of loss of skeletal muscle mass in cancer patients and be referenced in nutrition care of cancer patients under the onset of cachexia or parenteral/enteral nutrition. This data need to be confirmed with large pool of subjects and should be specified by stage of cancer or the site of cancer in future studies.

The purpose of this study was to investigate the relationship among urn leptin, nutritional status, and urn lipids, glucose of 99 middle school girls residing in Kyluggi-do, Korea. Subjects were assigned to one of three groups such as underweight(BMI < 20, n=38), normal(20$\leq$BMI<25, n=36) and over weight(BMI$\geq$25, n=25) groups. The nutritional status of the subjects was evaluated by anthropometric measurements, questionnaires, 24-hr dietary recalls and blood anal),sis. The results were as follows : The mean age, body weight, height and BMI were 13.93 years, 55.19kg, 158.40cm and 21.96kg/㎡ respectively. The mean menarche age of the subjects was 12.64 years and the mean daily energy intake was 94.22% off RDA for Koreans. The energy ratio from carbohydrate fat and protein was 63: 24: 13. Underweight group showed the lowest intakes of oils and fats among three groups(p<0.05). The mean serum levels of leptin, glucose, total cholesterol, HDL-cholesterol. LDL-cholesterol and triglyceride were 10.57ng/ml 78.80mg/dl, 12.29mg/dl, 48.07mg/dl, 93.50mg/dl and 78.61mg/d1, respectively. The mean atherogenic index was 2.37. There were significant increases in serum leptin, glucose, LDL-cholesterol, triglyceride and atherogenic index of subjects with increases in their BMIs. Serum leptin showed a significantly positive correlation with BMI(p<0.001), body fat percent(p<0.001). When BMI was adjused, serum leptin showed a significantly positive partial correlations with intakes of animal protein(p<0.05), milks and animal foods(p<0.05), Serum leptin showed a significantly positive correlation with serum glucose(p<0.05) total cholesterol(p<0.01), LDL-cholesterol(p<0.001), triglyceride(p<0.001) and atherogenic index(p<0.001), however, it had significantly negative correlations with HDL-cholesterol(p<0.05). Therefore, these results suggest that the increase of serum levels of leptin may elevate the risk of cardiovascular disease and lipids and some nutrient intakes may be related with serum leptin levels.

Alcohol dehydrogenases (AHDs) are enzymes responsible for the catalysis of the reversible conversion of various alcohols to their corresponding aldehydes and ketonesis. Until now cDNA sequences of ADH gene is informed exclusively from several diptean species. We describe here the cDNA sequence and mRNA expression of a putative ADH gene from the mole cricket, Gryllotalpa orientalis, and phylogenetic relationships among known insect ADHs. The G. orientalis ADH cDNA sequences comprised of 798 bp encoding 266 amino acid residues. The multiple sequence alignment of G. orientalis ADH gene and known dipteran ADHs shared 100％ identity in the nine amino acid residues that are important for the enzymatic activity in Drosophila melanogaster. Percent sequence identity ranged from 25％ to 32％ among all insect ADHs including both types of ADHs. G. orientalis ADH gene showed no clear resemblance to any dipteran species and type. Phylogenetic analysis of the deduced amino acid sequences of G. orientalis ADH gene with available dipteran ADH genes including both types of ADHs further confirmed that the G. orientalis ADH gene is not clearly assigned to either type of ADHs. Northern blot analysis revealed a stronger signal in the fat body than midgut and epidermis, indicating that the fat body possibly is a main site for the synthesis of the G. orientalis ADH protein.

High serum cholesterol level is a major risk factor for coronary heart disease(CHD). Nutrition therapy of hypocholesterolemic diets with increased physical activity is the essential step in the treatment of the hypercholesterolemic patients. The purpose of this study was to evaluate the short-term effect of intensive dietary therapy combined with regular exercise in lowering serum cholesterol level. Seventy three hypercholesterolemic outpatients(mean: 268.0$\pm$24.7mg/dL), aged 34 to 73(mean: 56$\pm$9.8yrs), who visited cardiology OPD of Yonsei Cardiovascular Center from April through October, 1998 were studied. Anthropometric measurements, usual nutrient intake survey using semiquantitative food frequency questionnaire, and daily nutrient intake analysis were performed. The nutrition counseling for the hypocholesterolemic diet and exercise therapy was performed individually. After a 4 week intensive dietary therapy, comparisons of body weight, nutrient intakes, and blood lipid concentrations were evaluated for the hypocholesterolemic effect of intensive diet therapy. After 4 weeks of intensive diet therapy, significant reductions in percent ideal body weight(p<0.01), saturated fat intake(p<0.01), and cholesterol intake(p<0.01) were observed. There were significant reductions in serum total cholesterol and LDL-cholesterol levels after 4 weeks of therapy by 8.1%(p<0.01) and 9.7%(p<0.01), respectively. Our results showed that intensive dietary therapy was effective in reductions of serum total and LDL-cholesterol levels. The goal for this dietary modification should not be temporary but rather be permanent in eating behavior accompanied by appropriately increased physical activity.

A nutritional survey was made in 45 healthy Buddhist nuns (age : 20-34 yr) who have been vegetarians for more than 5 years and 20 female college students (aga : 20-22 yr) as a control group in Kyungpook province. Daily calorie intake of the Buddhist nuns and students were 1947 and 1815 kcal, respectively. The ratio of percent calorie of carbohydrate : fat : protein from total calories in the Buddhist nuns was 84 : 11 : 5 and that of the students was 70 : 15 : 15, respecting. The Buddhist nuns had significatly higher carbohydrate intake but markedly lower lipid intake than the students. Daily intakes of thiamin, niacin and ascorbic acid in the Buddhist nuns were higher, but those of iron, calcium and vitamin A were lower than the recommended daily allowances. Compared with the students, the Buddhist nuns had greater intakes of ascorbic acid, vitamin A, thiamin, niacin, and calcium. Anthropometric measurement showed that the Buddhist nuns had significantly higher values than the students in body weight, skinfold thickness, body surface area, and obesity index. There were highly significant correlations between anthropometric measurements and obesity index(0.55< r <0.99). On the other hands, correlation coefficients between nutrients intakes and skinfold thickness and obesity were very low(0.01< r <0.37). The Buddhist nuns and students showed similar normal values of hemoglobin concentration, hematocrit, and blood pressure.

An experiment was carried out to study the effect of monensin administration on mammary functions in crossbred Holstein cattle. Fourteen non-pregnant late lactating crossbred Holstein cattle, approximately 270 days postpartum, were selected for the experiment. They were divided into two groups of 7 animals each. Seven animals in the treated group were given sodium monensin orally in a slow-release capsule. Animals in both control and treated groups were fed the similar diet to maintain milk production and body score at 2.5. Rice straw was fed as a source of dietary fiber throughout the experimental period. After monensin administration, a significant increase in the molar percent of ruminal propionate (p<0.05) and a significant decrease in the molar percent of ruminal acetate (p<0.05) were apparent in comparison to the pretreated period. The ratio of acetate to propionate concentration decreased significantly after monensin administration (p<0.05), while it was maintained at the similar level throughout the period of experiment in the control group. Monensin did not affect the molar percent of ruminal butyrate and valerate. The concentration of milk allantoin between the control group and monensin treated group was not different. An excretion rate of allantoin in milk decreased in animals treated with monensin (p<0.05). Mammary blood flow did not show significant difference between control and monensin treated groups. The plasma glucose concentration, arteriovenous concentration difference and mammary gland uptake of glucose remained constant in both groups. Milk yield of the later stage of lactation in the control group declined during lactation advance while a tendency to increase in the milk yield was apparent after 21 days monensin administration. Milk compositions for concentration of lactose, fat and protein in both control group and monensin treated group did not change throughout the experimental periods. From these results, it can be concluded that the action of monensin could affect the ruminal fermentation pattern. Monensin could not increase milk yield in the late lactating period.

This study was performed to investigate the effects of very low calorie diet (VLCD) using newly meal replacements that contain the wild grass extracts based on Samul-tang ingredients on weight reduction and health in the obese adult women ($BMI{\geq}25\;kg/^2$) for four weeks. Seventy five women participated in this experiment. Subjects were randomly classified three groups: 1) General Diet group (GD group, n=25) consumed 3 regular meals within 600 kcal/day, 2) Meal replacements group (MR group, n=25) consumed 1 regular meal and 2 meal replacements within 600 kcal/day, 3) Herbal Meal replacements group (HMR group, n=25) consumed 1 regular meal and 2 meal replacements within 600 kcal/day. Anthropometric measurements, body composition, biochemical measurements and body symptoms were assessed before (the initial) and after (the 4th week) the study. Anthropometry measurements such as weight, waist and hip circumference, and BMI and body composition such as body fat percent, fat mass significantly decreased in all groups after diet intervention. Anthropometric measurements and body composition of the ]lim group significantly decreased more than those of GD and MR groups. Serum Total cholesterol was significantly decreased in all groups. However, there was no significant difference among three groups during the experimental period. HMR group had significantly less felt a pain than GD and MR groups in body symptoms such as anemia, powerlessness, vomiting, constipation and dryness of skin during the experimental period. Therefore, very low calorie diet (VLCD) using meal replacements that contain the wild grass extracts based on Samul-tang ingredients was very effective on weight reduction and health in the obese adult women.
