This study investigated the effect of exercise training and garlic powder ingestion on blood lipids and antioxidants activity in rats. Twenty-eight male Sprague Dawley rats were fed a high-fat diet with or without garlic powder (500 mg/kg) for four weeks as grouped in control (CON), exercise (EXE), garlic (GAR), and garlic + exercise training (GAREXE), respectively. EXE and GAREXE were trained on the treadmill for the same periods. Weight of fats (mesentery, perirenal, and epididymal) were weighed and blood glucose, triglycerides (TG), total cholesterol (TC), and high density lipoprotein- cholesterol (HDL-C) were analyzed and low density lipoprotein-cholesterol (LDL-C) was calculated. Malondialdehyde (MDA) and superoxide dismutase (SOD) for lipid peroxidation were analyzed in liver tissue. Body weight in GAREXE was significantly lower in the statistics than that in other groups (p<0.05), and the volume of fat in GAR and GAREXE was also much lower (p<0.05). Blood glucose was significantly lower in EXE and GAR (p<0.05), however, there was no effect of exercise training. Blood TG was lower in GAR and GAREXE (p<0.05), however, there was no effect of exercise training. HDL-C was significantly improved in EXE and GAR compared to CON (p<0.05), and GAREXE was higher than EXE (p<0.05). MDA content was considerably lower in GAREXE compared to EXE (p<0.05), and SOD activity was much higher in other groups compared to CON (p<0.05). In addition, GAREXE was significantly higher than EXE and GAR, thus there was significant increase when a garlic diet was carried out together with exercise (p<0.05). These results suggested that garlic powder ingestion during the training periods had a beneficial effect of lowering glucose and enhancing blood lipids profiles. Moreover, it also has antioxidant effects, which means that it could possibly suppress aging. It is necessary to inspect various effects of garlic with a variety of research methods regarding sampling process, production process, intake method, etc.

Purpose : Vitamin D plays a key role in bone mineralization of the skeleton and vitamin D deficiency can lead to rickets. It is well known that vitamin D deficiency is common in breast fed infants. Of these patients, clinically, some have no signs of rickets, but laboratory and radiographic findings are diagnostic for vitamin D deficiency rickets (subclinical vitamin D deficiency rickets). The purpose of this study is to clarify current causes and ways to prevent this disease. Methods : We reviewed the clinical and laboratory characteristics of children who were incidentally diagnosed as subclinical rickets during treatment of other disease such as pneumonia, gastroenteritis, urinary tract infection at Eulji Hospital, Seoul, Korea from March, 2003 to July 2007. Results : Eight patients (six boys and two girls) were diagnosed with subclinical vitamin D deficiency rickets. The mean age of the patients was $12.6{\pm}5.8months$, and they were diagnosed from January to July. The associated diseases were pneumonia, urinary tract infection, acute gastroenteritis, and iron deficiency anemia. All patients were breast-fed. Two showed growth failure. The mean serum alkaline phosphatase was $1995.8{\pm}739.5IU/L$, the mean calcium count was $9.5{\pm}0.6mg/dL$, and the mean phosphorus content was $3.6{\pm}1.5mg/dL$. The mean intact parathyroid hormone was $214.8{\pm}155.9pg/mL$ (reference range, 9-65), the mean 1,25-dihydroxyvitamin D was $82.4{\pm}49.3pg/mL$ (reference range, 2070), and the mean 25-hydroxyvitamin D was $29.6{\pm}10.6ng/mL$ (reference range, 1030). A radiographic examination showed cupping, fraying, and flaring of metaphyses in all patients. Six patients were administered calcitriol (400 IU/day) for three months. A consequent radiographic and laboratory examination showed improvement. The first two patients were initially diagnosed with metaphyseal dysplasia, without the detection of vitamin D deficiency and they spontaneously improved without vitamin D supplements. However, two years later, they showed mild scoliosis and metaphyseal dysplasia, respectively. Conclusion : Breast-feeding without supplementation involves high risk of vitamin D deficiency. Some infants may also develop rickets; therefore, such groups should be considered for vitamin D supplementation.

Purpose : The purpose of this study was to look at prevalences of abnormal serum aminotransferase levels and abnormal serum total cholesterol levels among adolescents with obesity in Seoul area. Methods : Body mass index[$BMI(kg/m^2)$], serum aspartate aminotransferase(AST) alanine aminotransferase( ALT), and total cholesterol levels were measured in 26,876 adolescents(male : 13,287, female : 13,589) of first grade of high school in Seoul between the ages of 15 and 16 years, enrolled in a large health examination survey by Seoul School Health Center(SSHC) in 2001. Obesity was defined as BMI more than 95th percentile for age and sex and normal weight was defined as BMI between 25th percentile and 75th percentile for age and sex. Abnormal levels of AST, ALT and total cholesterol were defined as more than 95th percentile for age and sex. Results : The BMI at 95th percentile was 28.7 in males and 26.9 in females. The prevalence of abnormal AST levels was higher in obesity group than in normal weight group. In males, those were 23.7% and 3.7%, respectively(P<0.01, $x^2-value$ : 529.2). In females, those were 11.8% and 4.9 %, respectively(P<0.01, $x^2-value$ : 56.3). The prevalence of abnormal ALT levels was significantly higher in the obesity group compared with the normal weight group. In males, those were 33.9% and 1.7%, respectively(P<0.01, $x^2-value$ : 1,693.4). In females, those were 22.3% and 3.9%, repectively(P<0.01, $x^2-value$ : 397.6). The prevalence of abnormal total cholesterol levels was higher in the obesity group than in the normal weight group. In males, those were 16.8% and 3.5%, respectively(P<0.01, $x^2-value$ : 268.3). In females, those were 9.0% and 5.4%, respectively(P<0.01, $x^2-value$ : 14.2). Conclusion : This study revealed that the prevalences of abnormal AST, ALT and total cholesterol level were higher in the obese group than in the normal weight group.

Purpose : Breastfeeding should be recommended for infants born to mothers with chronic hepatitis B Infection after postexposure prophylaxis. However, high proportion of these mothers are reluctant to engage in breastfeeding in Korea. This survey was taken to identify the cause of that reluctance. Method : Questionnaires were given to mothers with chronic hepatitis B infection who were registered at the 'Hepatitis B Perinatal Transmission Prevention Program' operated by Korea Center for Disease Control and Prevention. They visited a community health center for blood sample collection and signed a consent paper. The questionnaires were sent to the mothers. Result : Among 839 mailed questionnaires, 114 were returned marked 'address unknown'. The overall reply rate was 17% (n=125). Among responders, 52% (n=62) were breastfeeding and 48% (n=60) were formula-feeding. The most influential factor for breastfeeding was the mother's own decision (75%) and the obstetrician's recommendation (17%). For formulafeeding mothers, their decisions were influenced by obstetricians (57%), and by their own thinking (28%). The relationship between breastfeeding and perinatal prophylaxis failure was recognized as 45% 'related' and 50% 'not-related'. A total of 91% of breastfeeding mothers replied that they will breast-feed again. Among formula-feeding mothers, 78% answered that they will breast-feed if they were known that 'there is no direct relationship between breastfeeding and perinatal prophylaxis failure'. Conclusion : Despite the fact that there is no direct relationship between breastfeeding and perinatal prophylaxis failure, many were reluctant to breast-feed. Healthcare professionals have influence over the mothers for decision making. It will be necessary to educate healthcare personnel so that they can make a conceptual change as well as to promote the fact to the general public.

Purpose: With a remarkable increase in the prevalence of childhood obesity, the prevalence of nonalcoholic fatty liver disease is assumed to be increasing. The aim of this study is to evaluate the prevalence of nonalcoholic fatty liver disease, hyperlipidemia, and glucose intolerance in normal and obese children. Methods: A total of 2,206 elementary students (boys: 1340, girls: 866) were grouped according to obesity index; normal group and obesity group (mild, moderate, severe). Aspartate aminotransferase (AST, SGOT) and alanine aminotransferase (ALT, SGPT) were measured with total cholesterol, triglyceride, and fasting blood glucose. Results: Compared with the 4.6% of elevated aminotransferases in normal group, obese groups showed significantly higher prevalence; 12.1% in mild obesity group, 19.4% in moderate group, and 21.6% in severe group (p<0.0001). The prevalence of hypertriglyceremia was 16.9% in normal weight group, which was significantly lower than obesity group (mild obesity group 30.3%, moderate and severe 37.6%, 38.2% each). In boys, the prevalences of elevated aminotransferases in normal weight and obese groups (mild, moderate, severe) were 6.8%, 18.0%, 23.0%, and 26.0%, respectively (p<0.0001). In girls, those were 2.1%, 5.1%, 12.0%, and 12.6%, respectively (p< 0.0001). The prevalence of hypertriglyceremia was relative to severity of obesity in boys and girls (p<0.0001). Conclusion: The prevalence of elevated serum liver enzymes increased with severity of obesity. For the prevention and treatment of fatty liver and hypertriglycemia, it is important to lower the obesity degree and enforce the education for a weight loss in the student and the parents.

This study was performed to determine the effect of onion peel extract using 70% ethanol and 95% ethanol on its anti-oxidation activity, small intestine length, and intestinal villi of high-fat fed mice. Five percent of each onion peel extract using 70% and 95% ethanol showed significant decrease of E. coli and Listeria monocytogenes. Total phenolic contents of onion peel extracts using 70% and 95% ethanol were $166.89{\pm}0.03$ mg/g and $160.89{\pm}0.13$ mg/g, respectively. In anti-oxidation activity, DPPH radical scavenging activity and SOD-like activity of onion peel extracts were higher at 100 ug/ml concentration. The obese mice were fed high-fat diets supplemented by 1, 3, and 5% of the onion peel extracts using 70% and 95% ethanol for 4 weeks. Body weight, feed intake, feed efficiency, small intestine weight, length, villi's length, and number of bacteria in intestine were determined. Body weight of mice fed 5% of onion extracts using both 70% and 95% ethanol was significantly lower than that of control (p<0.05). However, feed intake was increased in mice fed 5% of onion extracts at both fermented ethanol levels. Small intestine weight and length of mice showed no significant change with supplementation of the onion peel extracts. However, length of small intestine villi was significantly longer than that of control. Total bacteria counts of Cl. Perfringenes and E. coli in small intestine of the mice were significantly reduced by supplementation of 5% of onion extract using ethanol, while lactic acid bacteria were increased. These results suggest that 5% of onion peel extracts using ethanol at either 70% or 95% concentration have potential to be used as an additive for body weight control and enhanced gut health; however, more research on its effectiveness is needed.

Purpose : Obesity has become a pandemic and especially the prevalence of childhood obesity has increased remarkably over the past years. Childhood obesity is often accompanied by the expected morbidities such as hyperlipidemia, fatty liver and glucose intolerance. We evaluated the pattern of alteration in the body mass index (BMI), serum adiponectin concentration, insulin resistance (HOMA-IR), and complication rates after one year follow-up. Methods : Forty two obese children (age: 8-15 years, 95th percentile of BMI for age and sex) were examined twice annually on June, 2004 and July, 2005. The body mass index (BMI) and sexual maturityrating (SMR) were determined annually by the same examiner and serum fasting glucose, liver enzyme, lipid profiles, adiponectin, insulin and HOMA-IR were measured and annual results were compared. Upper abdominal sonography was performed to detect fatty liver. Results : BMI ($25.3{\pm}2.9kg/m^2$ vs. $26.0{\pm}2.9kg/m^2$) and HOMA-IR ($3.6{\pm}1.8$ vs. $4.7{\pm}1.9$) have increased significantly after one-year follow-up. The serum adiponectin concentration ($17.2{\pm}5.2g/mL$ vs. $12.6{\pm}5.2g/mL$) has decreased after one year. The prevalence of hyperlipidemia and fatty liver were not changed significantly but that of hyperinsulinemia increased after one-year. HOMA-IR showed a positive correlation with BMI and SMR, but was negatively correlated with serum adiponectin concentration. Conclusion : Obese children in our study showed significant increment of insulin resistance during one year. These results suggest that well-organized and continuous obesity control is required especially for obese adolescent to prevent complication of obesity.

Purpose : Glycogen storage disease type III (GSD-III) is a rare autosomal recessive disorder of glycogen metabolism. The affected enzyme, amylo-1,6-glucosidase, 4-alpha-glucanotransferase (AGL, glycogen debranching enzyme), is responsible for the debranching of the glycogen molecule during catabolism. The disease shows clinical and biochemical heterogeneity, reflecting genotype-phenotype heterogeneity among different patients. In this study, we aim at analyzing mutations of the AGL gene in three unrelated Korean GSD-III patients, and characterizing their clinical and laboratory findings. Methods : We characterized the clinical features of three unrelated Korean GSD-III patients by biochemical, histological and imaging studies. The 35 exons and part of exon-intron boundaries of AGL were analyzed by direct sequencing using genomic DNA extracted from the peripheral leukocytes of patients. Results : Diverse clinical features were observed in these patients including hepatomegaly (all patients), seizures (patient 2), grow th failure (patients 1 and 2), hyperlipidemia (patients 1 and 3), raised transaminase and creatine kinase concentrations (all patients), and mild cardiomyopathy (patient 2). Liver transplantation w as performed in patient 2 due to progressive hepatic fibrosis. A dministration of uncooked corn starch maintained normoglycemia and improved biochemical and growth profiles. DNA sequence analysis revealed mutations in 5 out of 6 alleles. Patient 1 was a compound heterozygote of c.1282 G>A (p.R428K) and c.1306delA (p.S603PfsX6), patient 2 had c.1510_1511insT (p.Y 504L fsX 10), and patient 3 had c.3416 T >C (p.L 1139P) and c.1735+1 G>T (p.Y 538_R578delfsX 4) mutations. A part from the p.R428K mutation, the 4 other substitutions identified w ere nov el. Conclusion : GSD-III patients display variable phenotypic characteristics resembling those of GSD-Ia. Molecular defects in the AGL gene of Korean GSD-III patients are genetically heterogeneous.

Obesity is associated with an increased risk of many diseases including type 2 diabetes mellitus, hypertension, and hyperlipidemia. The flowers of Chrysanthemum boreale have been used as traditional medicines for the treatment of diseases such as obesity and type 2 diabetes mellitus. This study aimed to evaluate the effect of C. boreale Makino flower essential oil (CFEO) on adipocyte differentiation using preadipocyte cell line 3T3-L1. CFEO at concentrations between 0.1 and $5{\mu}g/ml$ did not affect 3T3-L1 cell viability. A CFEO concentration of between 0.1 and $1{\mu}g/ml$ significantly inhibited lipid accumulation during MDI-induced differentiation in 3T3-L1 cells in a dose-dependent manner, reaching a maximal level at $1{\mu}g/ml$ ($28.94{\pm}2.01%$; approximately 30% of control treated with MDI alone). Western blot analysis revealed that CFEO concentrations between 0.1 and $1{\mu}g/ml$ suppressed the activations of three adipogenic transcription factors in the MDI-stimulated 3T3-L1 cells: peroxisome proliferator-activated receptor ${\gamma}$; CCATT/enhancer binding protein ${\alpha}$; and sterol regulatory element binding protein-1. Moreover, the expressions of lipogenic enzymes, acetyl-CoA carboxylase, and fatty acid synthase were also inhibited by treatment with CFEO between 0.1 and $1{\mu}g/ml$. CFEO may therefore be a promising functional material for obesity prevention.

Objectives: This study was designed to examine the effects of extracts of Ojeoksangamibang($W{\check{u}}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) on the lipid lowering, anti-oxidation and concentration of proinflammatory cytokines and was investigated on hyperlipidemic rats. Methods: Male rats weighing $182.39{\pm}4.71g$ were fed high fat diet for 8 weeks and 36 rats(above 400 g) were divided into 4 groups. Each of 9 rats was divided a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1 time/1 day) for 4 weeks. And we fed each experimental group of rats basal diet and administered an extract of Ojeoksangamibang($W{\check{u}}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) extracts(100 mg/kg, 200mg/kg, 300 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of proinflmmatory cytokines, anti-oxidative activity and $TNF-{\alpha}$, Apo-B, Apo-E and leptin gene expression. Results: 1. Concentration of plasma free fatty(FFA) showed no significant difference in all the treatment groups. Concentration of plasma triglyceride(TG) showed a significant decrement in the 300 mg/kg in Ojeoksangamibang($W{\check{u}}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) groups than that of control group. 2.
