The purpose of this study was to examine a questionnaire survey on nutrition knowledge, dietary behaviors and the evaluation of nutrient intakes in regard to frequency of eating breakfast for a total 383 high school female students in Chuncheon area. The subjects were categorized into 3 groups according to frequency of breakfast : eating breakfast group (6-7 times/week, 49.1%), sometimes eating breakfast group (3-5 times/week, 22.2%), skipping breakfast group (${\leq}2$ times/week, 28.7%). The eating breakfast group and sometimes eating breakfast group have better grades on nutrition knowledge related to breakfast than the skipping breakfast group. The skipping breakfast group have a smattering of nutrition knowledge like, the importance of having breakfast, maintaining calories, and the brain's energy resource. There was a strong correlation between the frequency of breakfast and dietary behavior grades. The students who skip breakfast have irregular eating habits and their eating speed was improper. Also, their frequency of taking in cereals, proteins, fruits, vegetables, and dairy products was poor. The results of the survey on nutrition intake show that while, students who eat breakfast are consuming only folate, calcium and iron at a less than recommend intake, the students who skip breakfast are consuming vitamin $B_2$, niacin, vitamin C, vitamin $B_1$ as well as folate, calcium, and also iron at a less than recommended intake. Based on these results, it is necessary to develop an awareness program that emphasizes the importance of breakfast and accurate nutrition knowledge for students.

The purpose of this study was to investigate the effects of glasswort powder intake on lipid metabolism. Rats were divided into three groups: a group fed a normal diet (CON), one fed a high fat diet (HFC), and one fed a high fat diet with glasswort powder (HFG). They were fed their respective diet for four weeks. Body weight was significantly lower (9%) in the HFG group than in the HFC group at the fourth week. According to the feces analysis, the HFG group showed the highest fat level (120% vs. CON; 138% vs. HFC) and fecal calories (110%). The concentration level of TG and LDL-C was 71.8% lower in the HFG group compared to the HFC group, while the concentration level of HDL-C was 152% higher in the HFG group. Expression of FABP in the liver was 197% greater in the HFG compared to the HFC group, with the expression of CPT-1 showing a similar tendency. These results suggest that glasswort powder intake suppresses weight gain and improves fat metabolism at the level of liver cells. From these results, we suggest that glasswort powder is effective against obesity by inhibiting the absorption of fat in the digestive tract.

Estrogen deficiency is associated with increased body weight and fat mass, resulting in obesity-associated complications such as insulin resistance, cardiovascular disease, and type-2 diabetes. The present study was performed to investigate the effect of black rice (Oryza sativa L.) extracts (BRE) on body weight and fat mass in ovariectomized rats. Ovariectomized (or sham-operated) rats were randomly blocked into three groups (n=8~10 per group): sham operated group (S), ovariectomized control group (OVX), and ovariectomized group with BRE 30 mg/kg B.W. (BRE). High fat diet (fat calories 45%) was fed to all experimental rats for 12 weeks. Final body weight, weight gain, and body fat weight showed significant increases in the OVX group, whereas they were reduced by BRE supplementation. Serum TAG, T-chol level, and adipocyte size were not significantly different among the three groups. However, ovariectomy-induced hepatic steatosis was improved in BRE-treated group. Moreover, in the BRE group, serum leptin levels was significantly lower and fecal total lipid concentrations was significantly higher compared to the OVX group. The gathered data suggest that BRE is a potentially useful ingredient to protect against estrogen deficiency-related obesity and its related diseases.

Carbamoyl phosphate synthetase 1 (CPS1) deficiency is an autosomal recessive urea cycle disorder which causes hyperammonemia. CPS1 is the first enzyme step in the urea cycle and almost patients present their symptoms during neonatal period. We report a case of CPS1 deficiency in a boy who developed symptoms including lethargy and seizure at 3 days of age. The ammonia level was up to $2,325{\mu}mol/L$, sodium benzoate (250 mg/kg/d) and high calories of both dextrose and lipid was promptly administered. Central access by experienced pediatric surgeon and emergent continuous hemodialysis by pediatric nephrologist was performed within 3 hours and ammonia was less than $100{\mu}mol/L$ at 5 days of age. Currently, he has showed excellent response to treatments including scavenging drugs and a low-protein diet. Despite of diffuse increasing signal intensity on cerebral white matters and basal ganglia on brain MRI, his development and weight gain were good at the last follow-up at 11 months of age. Molecular assay of the CPS1 gene demonstrated that patient had compound heterozygous for c.1529del ($p.Gly510Alafs^*5$) in exon 14 and c.3142-1G>C (IVS25(-1)G>C) in intron 25 and exon 26 boundary. The splicing mutation was novel mutation and inherited from patient's mother. Here, we report a neonatal lethal type CPS1 deficiency patient having novel mutation.

Purpose: In this study, we investigated the effects of chronic alcohol and excessive iron intake on mitochondrial DNA (mtDNA) damage and the progression of alcoholic liver injury in rats. Methods: Twenty-four Sprague-Dawley male rats were divided into four groups (Control, EtOH, Fe, and EtOH + Fe), and fed either control or ethanol (36% of total calories) liquid diet with or without 0.6% carbonyl iron for eight weeks. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, liver malondialdehyde concentrations were measured by colorimetric assays. Liver histopathology was examined by Hematoxylin-eosin staining of the fixed liver tissues. The integrity of the hepatic mtDNA and nuclear DNA was measured by long-range PCR. The gene expression levels of cytochrome c oxidase subunit 1 (Cox1) and NADH dehydrogenase subunit 4 (Nd4) were examined by real-time PCR. Results: Serum ALT and AST activities were significantly higher in the EtOH+Fe group, as compared to the Control group. Similarly, among four groups, liver histology showed the most severe lipid accumulation, inflammation, and necrosis in the EtOH + Fe group. PCR amplification of near-full-length (15.9 kb) mtDNA showed more than 50% loss of full-length product in the liver of the EtOH + Fe group, whereas amounts of PCR products of a nuclear DNA were unaffected. In addition, the changes in the mtDNA integrity showed correlation with reductions in the mRNA levels of mitochondrial gene Cox1 and Nd4. Conclusion: Our data suggested that the liver injury associated with excessive iron and alcohol intake involved mtDNA damage and corresponding mitochondrial dysfunction.

The purpose of this study is to identify instant noodle intake and consumption patterns of adults in metropolitan areas of Korea. There was a total of 702 subjects, 18 years of age and above, and data from the self-administrated questionnaires were collected and analyzed using comparative statistical analysis, including frequency, chi-square, t-test, and one-way ANOVA. According to the results, preference level for instant noodles among the adults was indicated to be $4.84{\pm}1.32$ and 54% of subjects either "liked" or "more than liked" noodles. People in 20s liked them the most. Noodles in envelope type package with soup are highly preferred. The most common reason why they chose to eat instant noodles was "convenience." At the same time, people avoid them because of their bad nutrition and calories. Half of the subjects consume instant noodles at least once a week mainly for lunch and dinner as a substitute for their meal. In the case of eating-together-with-family was the largest. 72.4% of subjects consumed entire soup additive content and 20.6% of them eat almost without soup because of being full and worrying that it might be harmful to health. Significant difference was shown in the preference level and intake patterns depending on respondents' general characteristics. Limitations and future research directions are also discussed.

The objective of this study was to estimate changes on the flood and nutrient intake patterns of men over thirty years old in Jeon-Ju area. The first survey was conducted from December in 1991 to January in 1992, tile second one from January to February in 1994 and the third one from July to August in 1997. The nutrition survey using 24-hour recall method was executed to 303 subjects : 89, 82, 132 in 1991, 1994 and 1997, respectively. Results of the study are as follows : Kimchi, rice, garlic and onions were the most frequently eaten food items. Total daily intakes of foods were 85 : 15, 81 : 19 and 81 : 19 in 1991, 1994 and 1997, respectively. The average numbers of foods per person were 15.7, 20.1 and 21.9 daily in 1991, 1994 and 1997, respectively and tends to increase significantly(p<0.05). The minimum numbers of foods per person were 4, 7 and 9 and the maximum numbers of foods per person were 27, 35 and 39 in 1991, 1994 and 1997, respectively. KDDS(Korean\`s Dietary Diversity Score) is determined by how many among the five food groups (cereals, vegetables, meats, milks, oils groups)were consumed per day. Most subjects earned the KDDS "3" ; 61, 46 and 42% in 1991, 1994 and 1997, respectively. Average daily energy intakes wee 1,62㎉(72% of RDA), 2,063㎉(89% of RDA) and 1,818㎉ (79% of RDA) in 1991, 1994 and 1997, respectively. Energy intake rates of cereals : total energy intake were 65, 59, and 60% in 1991, 1994 and 1997, respectively, which were decreasing. Protein intakes were 58g(72% of RDA), 79g(107% of RDA) and 71g(97% of RDA), respectively and animal protein comprised 46, 53, and 59%, respectively ; which were increased. Fat intakes were 12g, 20g and 20g, respectively and animal protein comprised 38, 46, and 48% ; which were increased. Fat intakes were 12g, 20g and 20g, respectively, of which animal fat comprised 46, 53, and 59%, respectively ; which were increased, too. Malnourished (under 75% of RDA) rates were respectively 64, 34, and 47% in terms of energy ; 64, 31 and 33% in protein ; 67, 51, and 61% in calcium ; 53, 26, and 18% in iron ; 85, 74 and 84% in Vitamin A. Super-nourished(above 125% of RDA) rates were respectively 1, 13, and 3% in energy ; 1, 29, and 21% in protein ; 5, 18, and 7% in calcium ; 16, 31, and 7% in iron ; 16, 31, and 7% in Vitamin A, 42, 76, and 62% in Vitamin C. The percentages of calories from protein : fat : carbohydrate were 14 : 12 : 74, 15 : 16 : 69 and 16 : 17 : 67 in 1991, 1994 and 1997, respectively. KDDS(number of five food groups per day), Meal Balance(number of five food groups per meal), DVS(average numbers of foods per person), amount of foods correlated positively with all the nutrient intakes(p<0.05). KDDS was positively correlated with energy, protein, fat, calcium, thiamin, riboflavin and niacin(p<0.05)in(p<0.05)
