Authors obtained the results of the investigation for healthy people through the routine health examination of public officers and school personnels in private schools which were conducted in 1986. The results were as follows; 1) Those who were above 20% incidence of body weight for 3917 study population were revealed 5.2% in males and 15.1% in females of $45{\sim}49$ years of age, 6.8% in males and 24,4% in females of $50{\sim}54$ years old, 5.8% in males and 13.5% in females of $55{\sim}59$ years old, and they showed that the incidences were significantly higher in females than in males at 0.01, 0.01 & 0.05 in P-values respectively. 2) Mean$\pm$SD of total cholesterol level for 3,265 healthy people with both sexes combined showed $181.63{\pm}34.67$ and it was $188.61{\pm}33.96$ in people of $40{\sim}59$ years old with both sexes combined. Mean$\pm$SD of fasting blood sugar level for 3,266 healthy people showed $87.28{\pm}11.67$ and that in $40{\sim}59$ years of age were $89.14{\pm}11.74$. Therefore, mean$\pm$2SD of total cholesterol and fasting blood sugar were $112.26{\sim}250.98mg/dl$ in males and $58.93{\sim}110.61mg/dl$ in females. 3) This investigation showed 3.0% in above 251 mg/dl of total cholesterol and 3.5% in above 111 mg/dl of fasting blood glucose. 4) Those who were above 251 mg/dl of total cholesterol and above 111 mg/dl of blood glucose in above 20% incidence of body weight according to the Broca' index were 12.9% and 7.6% respectively. 5) Those who have hypertension according to the criteria of WHO with obesity of above 20% incidence of body weight showed 8.4% in both sexes (8.2% in males and 8.7% in females). 6) Blood pressures increased according to more aging and gaining body weight.

Objectives: This study was designed to investigate the anti-obesity, anti-diabetic and anti-inflammatory effects of Platycodi radix on obese type 2 diabetes mouse model. Methods: Obese type 2 diabetes mouse model was induced by Surwit's high fat, high sucrose diet for 8 weeks. Models were divided into 4 groups of normal diet (ND, n=10), high fat and high sucrose diet (HFD, n=10), high fat and high sucrose diet with Platycodi radix (PR, n=10), and high fat and high sucrose diet with Metformin (Met, n=10). Body weights were measured every week. After 7 weeks fasting, blood sugar and oral glucose tolerance tests were conducted. After 8 weeks blood samples were taken from mouse hearts and analyzed biochemically. Lipid profile, fructosamine, leptin and weight of epididymal fat pad and liver were measured. Adipose tissue macrophage percentage was analyzed by fluorescence-activated cell sorting (FACS). Results: Compared with the HFD group, body weight, glucose level, fructosamine, weight of epididymal fat pad and adipose tissue macrophage percentage decreased in the PR group. Conclusions: These results suggest that Platycodi Radix has anti-obesity, anti-diabetic, and anti-inflammatory effects on obese type 2 diabetes mouse model.

The hypolipidemic and hypoglycemic effects of two dietary dosages (0.1% and 0.5%) of water and 80% ethanol extracts from hot-air dried Orostachys japonicus A. Berger were evaluated in the serum and organ tissues of streptozotocin-induced diabetic rats. The STZ-induced diabetic groups supplemented with the O. japonicus extracts showed significantly higher body weight compared to a diabetic control group at the end of experiment. The extracts exhibited substantial hypoglycemic effects by significant reductions of fasting blood glucose levels at all time points tested compared to the initial stage before treatment of the extracts. Declines of serum and hepatic triglyceride levels were greater than declines of total cholesterol in the groups treated with the 0.5% O. japonicus extract (DBW2 and DBE2) when compared to the DBC group. Hepatic glycogen content was higher in the groups treated with O. japonicus extract, while lipid peroxide content was decreased in these treated groups compared to the DBC group. Hepatic antioxidant activity was significantly increased in the groups supplemented with the O. japonicus ethanol extract The hypolipidemic and hypoglycemic effects of the O. japonicus ethanol extract were significantly greater than the effects of the water extract. Based on this study, it seems that O. japonicus ethanol extract, due to its higher phenolic and flavonoid components than the water extract, may control blood glucose and alleviate hyperlipidemia in diabetes.

Recent epidemiologic and clinical students have shown that plasma cholesterol and triglyceride levels are independent risk factors for coronary heart disease. However, there is not much data on the characteristics of anthropometry and lipid profiles of hypercholesterolemia patients with hypertiglyceridemia. In this study, 112 hypercholesterolemic subjects$(T.C{\ge}240mg/dl)$ were divided into two groups by their plasma triglyceride levels. We compared the anthropometric measurements and lipid profiles of the subjects between the two groups : the simples hypercholesterolemic group(SHC, TG<200mg/dl) and the combined hypercholesterolemic group$(CHC, TG{\ge}250mg/dl)$. The distribution of the subjects into the SHC and CHC groups was 36.6% and 47.3%, respectively. The frequency of the CHC patients decreased with age. The subjects in this group had higher weight, BMI, HWR, cricumferences of mid arm, waist, hip and thigh, and skinfold thicknesses of biceps and triceps than those of the SHC subjects. The difference of plasma total cholesterol level was mainly due to the difference of VLDL-C levels. These differences resulted in the CHC subjects having higher atherogenic indexes and T-C/HDL-C ratios than those of the SHC subjects. Also, the former had higher Apo-B and insulin levels than those the latter. However, blood pressure, fasting blood glucose and HDL-C levels were not significantly different between the two groups. These results suggest that hypercholesterolemic patients with hypertriglyceridemia have riskier lipid profiles for CHD than those of patients with normal triglyceridemia. They also indicate that CHC is closely associated with glucose resistance syndrome(obesity, hyperglycemia, hyperinsulinemia and hypertriglyceridemia), and more prevalent in young people.

PURPOSE. The purpose of this study was to assess the prevalence and extent of clinical attachment loss of periodontal tissue and to find out variables related to clinical attachment loss (CAL) in Korean adults older than 40 years of age. MATERIALS AND METHODS. Data were collected from 2,519 subjects who were part of a cohort study conducted in Ansan city by Korea University Medical School for Korean Genome project. Age, sex, smoking, drinking, fast glucose, blood pressure, obesity and total cholesterol levels were examined. The oral examination included probing pocket depth, gingival recession and CAL of Ramford's teeth. The severity of periodontitis was classified based on the mean value of CAL. The relationship between each risk factor and the severity of CAL was independently estimated using the chi-square test, the test or one-way ANOVA. Multiple regression analysis was used to determine the significance of each factor in the periodontal disease. RESULTS. The prevalences of clinical attachment between 1 and 3 mm, between 3 and < 5 mm, and ${\geq}$ 5 mm were 80.27%, 16.75% and < 1%, respectively. Although the univariate analysis showed age, gender, smoking, fasting glucose, blood pressure and total cholesterol levels were significantly related to the severity of CAL, multiple regression analysis indicated that age (P < .0001), gender (P < .0001) and smoking (P < .05) were only significantly related. CONCLUSION. Older age, male gender and smoking were significant risk factor for the increase of CAL, and these may be useful indicators of periodontitis high-risk groups.

BACKGROUND/OBJECTIVES: The anti-obesity effect of quercetin-rich onion peel extract (OPE) was suggested in rats, but information from human studies is limited. This study aimed to investigate the effects of OPE on the body composition of overweight and obese subjects. MATERIALS/METHODS: In this 12-week, randomized, double-blind, placebo-controlled study, parallel clinical trials were performed in overweight and obese Korean subjects. Randomly assigned subjects were instructed to take daily either the placebo (male, 6 and female, 30) or OPE capsules containing 100 mg of quercetin (male, 5 and female, 31). Body composition was measured by using bioimpedance and dual-energy X-ray absorptiometry (DXA). Resting energy expenditure (REE) and respiratory quotient (RQ) were evaluated by using indirect calorie measurement methods. Fasting blood levels of glucose, insulin, lipids, and leptin were determined. RESULTS: Quercetin-rich OPE supplementation significantly reduced the weight and percentage of body fat as measured by DXA (P = 0.02). These effects were not shown in the control group. Levels of blood glucose (P = 0.04) and leptin (P = 0.001 for placebo, P = 0.002 for OPE) decreased in both groups. Significant increases in REE and RQ were observed in both groups (P = 0.003 for placebo, P = 0.006 for OPE) and in the OPE group alone (P = 0.02), respectively. CONCLUSIONS: Quercetin-rich OPE supplementation changed the body composition of the overweight and obese subjects. This result suggests a beneficial role of the anti-obesity effect of OPE human subjects.

The purpose of this study was to evaluate nutrient intake and meal variety with breakfast eating in Korean adolescents using data from the 2008-2009 National Health and Nutrition Examination Survey. The analysis included 1245 adolescents aged 12 to 18 years. The subjects were divided into two groups according to breakfast skipping (BS: breakfast skipping, n = 235, BE: breakfast eating, n = 1110). The BS group was significantly higher in its frequency of eating soda drinks, instant noodle, and ice cream than the BE group. The BS group consumed significantly lower quantities of plant calcium and plant protein per 1,000 kcal compared to the BE group. Also the intake of cereal and vegetables in the BS group was significantly lower than those in the BE group, however, the intake of beverage in the BS group was significantly higher than that in the BE group. The average number of foods of the BE and BS groups were 29.50 and 25.85, respectively and revealed a statistical significance (p < 0.0001). The snack intake and % energy from snack intake of the BS group were significantly higher than those of the BE group. Also, the fasting blood glucose concentrations were significantly higher in the BS group compared to the BE group. In conclusion, adolescents who skip breakfast may have lower meal variety and higher blood glucose concentrations. Therefore, in support of proper dietary management, it is necessary to promote and encourage breakfast eating.

This study was conducted to evaluate the nutritional status and diabetes management of diabetic patients in the Health Center. General characteristics, food habits, food intakes and the knowledge about diet therapy were investigated from ninety one diabetes subjects. Anthropometric assessment such as weight, hight, triceps skinfold thickness, and biochemical measurement of fasting blood glucose(FBG), post prandial 2 hours blood glucose(PP2), and hemoglobin A1c(HbA1c) were obtained form the subjects. The results were summarized as following : 1. The average of age was 60.9 years old and 83.5% of subjects was illiterate and primary school graduated. 2. Relative Body Weight(RBW) and % body muscle were 96.18${\pm}$13.6 and 33.56${\pm}$7.01%, respectively. Obese subjects whose body weight exceeded 120% of the ideal values were 3.3%. 3. The 86.8% of subjects were managed by oral hyperglycemic agents. 4. The mean of FBG, PP2, HbA1c were 140.75${\pm}$44.43mg/㎗, 7.60${\pm}$1.88%, respectively. 5. The mean daily intake of calorie was 1407㎉, and 73.6% of subjects lower caloric intake than prescribed calorie. when the degree of dietary compliance was expressed as Tunbridge score, 18.7% of total subjects was grouped as satisfactory, where as 20.9% and 60.4% could be considered as tolerable and hopeless, respectively. The nutrients intake were lower than RDA except for Vitamin A and Vitamin C and the ratio of carbohydrate : protein : fat was 72 : 14 : 14. 6. The mean score of knowledge test about diet therapy was 3.52${\pm}$2.19 out of possible 14.00 points. The above results suggested that the most of diabetic patient showed the poor nutritional status and they faced the lack of knowledge about diabetes management.

Objectives: The purpose of this study was to investigate anti-obesity effect of Scutellariae Radix extract combined with metformin. Methods: Male C57BL/6 mice, 4 weeks of age, were used to set high-fat diet induced obesity model. They were grouped NOR (normal control), HFD (high fat diet control), MET (metformin, 100 mg/kg/day), MH2 (metformin 50 mg/kg/day+Scutellariae Radix 200 mg/kg/day), and HG4 (Scutellariae Radix 400 mg/kg/day). MET, MH2, and HG4 were orally administered for 10 weeks. Body weight was measured every week. Fasting blood glucose, triglyceride, total cholesterol (TC), high density lipoprotein, glutamic oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) were measured before sacrifice. Oral glucose tolerance test (OGTT) was also performed. Organ weight and internal fat weight were measured after sacrifice. Results: MH2 group showed a reduction of body weight when compared with HFD group. MH2 group showed stable blood level control which was calculated areas under the curves by OGTT. TC, GOT, GPT level, internal fat, and organ weight in MH2 group reduced. Conclusions: The combined treatment of Scutellariae Radix and Metformin has impact on treating obesity. Further studies are needed to evaluate the effect of Metformin and herbal medicine combination therapy.

Purpose: The purpose of this study was to investigate the knowledge and learning needs on coronary artery disease in diabetic patients by glycemic control. Methods: The subjects consisted of 188 patients at the hospital who had diabetes mellitus. Data was obtained using a knowledge and learning needs questionnaire from January to April 2006. Results: Treatment method, the levels of fasting blood glucose(FBG), and 2-hour postprandial blood glucose(PP2hr) showed meaningful differences between normo-glycemic group(HbA1c < 7%) and hyper-glycemic group($HbA1c{\geq}7%$). The levels of knowledge on coronary artery disease by glycemic control tend to show higher in normo-glycemic group. Etiology and prevention of coronary artery disease were significantly higher in normo-glycemic group than in hyper-glycemic group. The levels of learning needs on coronary artery disease by glycemic control tend to show higher in normo-glycemic group. The learning needs on items of diet control were higher in normo-glycemic group than in hyper-glycemic group. Conclusion: On the base of these results, we should focus on the coronary artery disease education for hyper-glycemic group. Also individual coronary artery disease educational program should be developed for the patients with different level of knowledge and learning needs.
