Objectives: We wanted to determine the distribution of the clustering of the metabolic risk factors and we wanted to evaluate the related factors in young schoolchildren. Methods: A cross-sectional study of metabolic syndrome was conducted in an elementary school in Seoul, Korea. We evaluated fasting glucose, triglyceride, HDL cholesterol, blood pressures and the body mass index, and we used parent-reported questionnaires to assess the potential risk factors in 261 children (136 boys, 125 girls). We defined the metabolic risk factors as obesity or at risk for obesity ($\geqq$ 85th percentile for age and gender), a systolic or diastolic blood pressure at $\geqq90th$ percentile for age and gender, fasting glucose at $\geqq110mg/dl$, triglyceride at $\geqq110mg/dl$ and HDL cholesterol at $\leqq40mg/dl$. Results: There were 15.7% of the subjects who showed clustering of two or more metabolic risk factors, 2.3% of the subjects who showed clustering for three or more risk factors, and 0.8% of the subjects who showed clustering for four or more risk factors. A multivariate analysis revealed that a father smoking more than 20 cigarettes per day, a mother with a body mass index of = $25kg/m^2$, and the child eating precooked or frozen food more than once per day were associated with clustering of two or more components, with the odds ratios of 3.61 (95% CI=1.24-10.48), 5.50 (95% CI=1.39-21.73) and 8.04 (95% CI=1.67-38.81), respectively. Conclusions: This study shows that clustering of the metabolic risk factors is present in young schoolchildren in Korea, with the clustering being associated with parental smoking and obesity as well as the child's eating behavior. These results suggest that evaluation of metabolic risk factors and intervention for lifestyle factors may be needed in both young Korean children and their parents.

The present study was undertaken to evaluate the effect of functional food, which was processed with fermented soybean as main ingredient (FS), on the body weight, organ weight, plasma glucose, and plasma lipid in diabetic rats caused by streptozotocin (STZ). The body weight was decreased more slowly in the FS group than in the diabetic, and the food intake increased significantly in all diabetic groups. The food efficiency was very low in all diabetic groups, but increased significantly in the FS groups than diabetic control (p＜0.05). In comparing the weight of organ, the weight of liver and kidney were increased in all diabetic groups than in the control, and decreased slightly in FS groups. The weight of heart and spleen were not different among all test groups. In the oral glucose tolerance test, the blood glucose in the diabetic group was the highest in 60 minutes. And the blood glucose in the FS group was the highest in 30 minutes, and decreased significantly after 120 minutes to the level of fasting glucose. The glucose in serum was decreased significantly in the FS groups fed the functional food for 4 weeks, compared to the diabetic control (p＜0.05). Total cholesterol, triglyceride and atherogenic index (AI) in serum were significantly higher in diabetic control, compared to the normal (p＜0.05), and decreased by 16.4％, 15.4％ and 48.3％, respectively, in the FS fed 400 mg/kg of functional food. HDL-cholesterol was increased significantly in the FS-400, compared to the diabetic control. These results support that functional food using fermented soybean improve glucose and lipid metabolism in diabetic rats.

In middle-aged men, abdominal obesity has been an important risk factor of coronary artery disease (CAD) as well as a predictor of hypertension, dyslipidemia, insulin resistance and glucose intolerance. Particularly, risks from abdominal obesity increase when adipose tissue accumulates in visceral compartment. Many studies showed that weight reduction by caloric restriction improves abdominal obesity and reduces lots of cardiovascular risk factors. Testosterone treatment also results in a significant decrease in visceral fat area and normalizes endocrine metabolism. However there is no study that compare the effect of caloric restriction with that of testosterone treatment. The purpose of this study is to investigate the effect of caloric restriction and that of testosterone treatment on body fat distribution, serum lipids and glucose metabolism in male patients with CAD. Forty five middle-aged overweight-obese men with CAD participated in 12 weeks' program. They were matched with age, body weight, body mass index (BMI) and divided into three groups : control group (n = 15) , caloric restriction group (-300 kcal/day, n = 15) and testosterone treatment group (testosterone undecanoate tablets, n = 15) . After 12 weeks, control group did not have any changes in anthropometries, lipid profile, body fat distribution, glucose metabolism and hormonal status. Expectedly, caloric restriction group showed decreases in body weight, BMI, waist to hip ratio, ％ body fat. Ten percentage of total cholesterol and 23% of triglyceride in serum were also decreased. In body fat distribution, total fat areas at both L1 and L4 levels were significantly reduced in this group without reduction in muscle of thigh and calf. However, testosterone treatment group did not have any significant changes in body weight, ％ body fat, serum lipid profile and abdominal fat distribution. In conclusion, weight reduction by caloric restriction is more beneficial in body fat distribution and serum lipid level than testosterone treatment in overweight male patients with CAD. This result suggests that modest weight reduction is possible to help decrease risk factors of CAD.

The purpose of this study was to examine the effects of Atractylodes lancea (A.l.) in a dose-dependent manner on lipid levels and plasma glucose in diabetic rats induced with streptozotocin (STZ). The Sprague-Dawley rats were randomly classified into five groups: normal, STZ-control and three experimental groups [A.l.-1, diabetic treated with ethanolic extract of A.l. (1 g/kg b.w.), A.l.-2, diabetic administered with ethanolic extract of A.l. (2 g/kg b.w.), and A.l.-3, diabetic administered with ethanolic extract of A.l. (3 g/kg b.w.)]. The normal and STZ-control group were fed an AIN-93 diet and the three experimental groups were administered with A.l. extract at doses of 1, 2, and 3 g/kg b.w./day, respectively, for 14 days. The plasma glucose levels in all the experimental groups were significantly lower than the STZ-control group after 14 days of treatment. The total cholesterol of the A.l.-3 and triglyceride levels, atherogenic index (AI) of all three experimental groups were significantly lower than the STZ-control group. The ALT and AST activities at A.l.-2, A.l.-3 were significantly lower than the STZ-control group. This result that demonstrate the administration of Atractylodes lancea can reduce hyperglycemia and hyperlipidemia risk in diabetic rats.

The present study was undertaken to evaluate the effect of Rhodiola sachalinensis root ethanol extract (RS), on the body weight, organ weight, plasma glucose and plasma lipid in diabetic rats caused by streptozotocin (STZ). The body weight decreased more slowly in the RS group than in the diabetic, and the food intake increased significantly in all diabetic groups. The food efficiency was very low in all diabetic groups, but increased significantly in the RS groups than diabetic control (p<0.05). In comparing the weight of organ, the weight of liver and kidney were increased in all diabetic groups than in the control, and decreased slightly in RS groups. The weight of heart and spleen were not different among all test groups. The glucose in serum was decreased significantly in the RS groups fed the RS for 4 weeks, compared to the diabetic control (p<0.05). Total cholesterol, triglyceride and atherogenic index (AI) in serum were significantly higher in diabetic control, compared to the normal (p<0.05), and decreased $16.7\%,\;18.3\%\;and\;45.0\%$, respectively, in the RS fed $300\;\cal{mg/kg}$ of RS. HDL-cholesterol was increased slightly more in the $RS-300\;\cal{mg/kg}$, compared to diabetic control. These findings suggest that RS treatment has protective effect in diabetes.

To find the antidiabetic activity of the tripterpenoid-rich fractions of Rubus coreanus (TRF-cor) and R. crataegifolius (TRF-cra) leaves or its main component niga-ichigoside $F_1$ (Niga-$F_1$), anti-hyperglycemic and antihyperlipidemic effects were investigated in the diabetic rat model induced by streptozotocin (STZ). Treatments of rats with 200 mg/kg of the TRF-cor, TRF-cra (each, p.o.) or 20 mg/kg of Niga-$F_1$ significantly inhibited the increase of blood glucose concentration about 44.8%, 28.7% or 20.6%, respectively, in the diabetic rats. In addition, treatments with those fractions inhibited the increase of serum concentrations of triglyceride, total cholesterol or LDL-cholesterol caused by STZ. The inhibitory rate on atherogenic index (AI) values of the TRFcor (200 mg/kg), TRF-cra (200 mg/kg) or Niga-$F_1$ (20 mg/kg)-treated groups were decreased about 55.7%, 36.3% or 22.6%, respectively, comparable to STZ-treated group. In the oral glucose tolerance test, treatment of TRF-cor or TRF-cra inhibited the increase of blood glucose concentration in the STZ-induced rats. Administration of 20 mg/kg of Niga-$F_1$ (p.o.) also exhibited similar effects with the effects of both TRFs at 200 mg/kg dose (p.o.). These results support that the triterpenoids, in particular Niga-$F_1$, are contributed to the antidiabetic effects of R. coreanus or R. crataegifolius.

Serum concentrations of Hanwoo steers and bulls as possible indicators of beef quality were analyzed to estimate their correlations with carcass traits. Blood samples were taken 2 months and right before shipping to abattoir and at the time of slaughter. And phenotypic correlation coefficients between serum concentrations and carcass traits were estimated. Beef yield index of steers was positively correlated with serum concentrations of total Protein (0.23), albumin (0.26), and calcium (0.31). But it was negatively co..elated with BUN (-0.30). Loin eye area was positively correlated with BUN (0.17) or with globulin (0.16). Back fat thickness was positively correlated with BUN (0.42) and inorganic phosphorus (0.20) being negatively correlated with total protein (-0.23), albumin (-0.33) and calcium (-0.33). Marbling score in the scale of 1 (scarcely marbled) through 9 (extremely marbled) was positively correlated with BUN (0.28) and negatively with IGF-I and calcium concentrations. Phenotype correlation coefficient of loin eye area with total protein concentration in the serum taken from steers right before shipment was estimated to be -0.16 and that with BUN was estimated to be -0.15. Serum concentrations of IGF, glucose, creatinine and on organic phosphorus from steers measured right before shipment were negatively correlated with respective correlation coefficient estimates as -0.21, -0.21, -0.19 and -0.18. Marbling score was negatively co..elated with serum creatinine (-0.16) measured at that time. Beef yield index of steers was positively correlated (0.31) with age adjusted calcium concentration in the serum taken at the time of slaughter. Correlation between body weight and BUN at slaughter was 0.17 At slaughter, loin eye area was negatively correlated with albumin (-0.19) and back fat thickness was also negatively correlated with age adjusted calcium concentration (-0.38). Marbling was negatively correlated with age adjusted calcium concentration(-0.17). Serum concentrations of testosterone, calcium and inorganic phosphorus taken in 2 months before slaughter were negatively but highly correlated with yield index(0.71, 0.67 and -0.71), respectively. Body weight at slaughter was positively was negatively correlated (0.67) with calcium level while dressing percentage was negatively (-0.69) correlated with serum glucose concentration, 2 months prior to slaughter. Correlation coefficients between back fat thickness and cortisol, between back fat thickness and inorganic phosphate were both positive (0.29 and 0.69). Marbling score was negatively correlated with creatinine (-0.81) and positively with BUN (0.87). Body weight loss during shipping was positively correlated with albumin and inorganic phosphate (0.77, 0.83). Yield index of bulls was positively correlated with serum testosterone concentration (0.66). Dressing percentage was positively and highly correlated with globulin (0.73). Back fat thickness of bulls, however, was negatively correlated with testosterone (-0.60). Loin eye area of bull carcasses was positively correlated with testosterone (0.40). Mar-blaine was negatively co..elated with creatinine (-0.55). Yield index of bulls and age adjusted HDLC concentration at slaughter was negatively correlated (-0.71). Dressing percentage of bulls was positively and highly correlated with globulin concentration (0.70). Back fat thickness was also positively correlated with HDLC (0.69) in the serum taken at slaughter. Correlation coefficients between carcass weight and triglyceride, between loin eye are and testosterone and between marbling score and creatinine or glucose were 0.51, -0.91 and -0.58, respectively.

Purpose: This study examined the effects of duck meats with turmeric powder on blood lipids in 10 female university students. Methods: The subjects received duck meat with 0%, 0.1%, 0.2%, and 0.4% turmeric powder and glucose, total cholesterol, triglyceride (TG), high-density lipoprotein (HDL)-cholesterol, and low-density lipoprotein (LDL)-cholesterol in their serums after 30, 60, 90, 120, and 180 min were measured. Results: The average height, weight, and body mass index of subjects were $159.6{\pm}2.6cm$, $51.3{\pm}3.5kg$, and $20.1{\pm}1.0$, respectively. The fasting glucose, ${\gamma}-glutamyl$ transferase (GGT), glutamic pyruvic transferase (GPT), glutamic oxaloacetic transferase (GOT), c-reactive protein (CRP), and hemoglobin were within the normal range. The ${\Delta}-AUC$ (area under the curve) of postprandial glucose, TG did not change, but ${\Delta}-AUC$ of postprandial total cholesterol and LDL were significantly decreased, and HDL was increased by intake of the duck meat with turmeric powder. Conclusion: This study shows that duck meats with turmeric powder affected the postprandial blood lipid levels.

The purpose of this study was designed to observe the effects of the feeding Prunus persica Batsch var. davidiana Max. extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride(TG), phospholipid(PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (groups BCG (cholesterol+water), BCPG (cholesterol+ Prunus persica 5.0 g% extract) than those in the control group (group BG, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remarkably lower in the group BCPG than those in the group BCG. In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Prunus persica 5.0 g% extract administration group was higher percentage than in the group BCG. The activities of aspartate aminotransferase (AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Prunus persica 5.0 g% extract administration group(group BCPG) than in the cholesterol diet group(group BCG). From the above research, Prunus persica Batsch var. davidiana Max. were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Prunus persica Batsch var. davidiana Max. was more effective therapeutic regimen for the control of metabolic derangements in adult disease.
