Background: We investigated the risk of cancer mortality according to obesity status and metabolic health status using sampled cohort data from the National Health Insurance system. Materials and Methods: Data on body mass index and fasting blood glucose in the sampled cohort database (n=363,881) were used to estimate risk of cancer mortality. Data were analyzed using a Cox proportional hazard model (Model 1 was adjusted for age, sex, systolic blood pressure, diastolic blood pressure, total cholesterol level and urinary protein; Model 2 was adjusted for Model 1 plus smoking status, alcohol intake and physical activity). Results: According to the obesity status, the mean hazard ratios were 0.82 [95% confidence interval (CI), 0.75-0.89] and 0.79 (95% CI, 0.72-0.85) for the overweight and obese groups, respectively, compared with the normal weight group. According to the metabolic health status, the mean hazard ratio was 1.26 (95% CI, 1.14-1.40) for the metabolically unhealthy group compared with the metabolically healthy group. The interaction between obesity status and metabolic health status on the risk of cancer mortality was not statistically significant (p=0.31). Conclusions: We found that the risk of cancer mortality decreased according to the obesity status and increased according to the metabolic health status. Given the rise in the rate of metabolic dysfunction, the mortality from cancer is also likely to rise. Treatment strategies targeting metabolic dysfunction may lead to reductions in the risk of death from cancer.

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 performed to evaluate the relationship between C-reactive protein(CRP) and carotid intima-media thickness(carotid IMT) in a population of middle-aged Koreans. Methods : A total of 1,054 men and 1,595 women(aged 40-70 years) from Kanghwa County, Korea, were chosen for the present study between 2006 and 2007. We measured high-sensitivity CRP and other major cardiovascular risk factors including anthropometrics, blood pressure, blood chemistry, and carotid ultrasonography. Health related questionnaires were also completed by each study participant. Carotid IMT value was determined by the maximal IMT at each common carotid artery. The relationship between CRP level and carotid IMT was assessed using multiple linear and logistic regression models after adjustment for age, body mass index, menopause(women), systolic blood pressure, total/HDL cholesterol ratio, triglyceride level, fasting glucose, smoking, and alcohol consumption. Results : Mean carotid IMT values from the lowest to highest quartile of CRP were 0.828, 0.873, 0.898, and 0.926 mm for women(p for trend<0.001), and 0.929, 0.938, 0.949, and 0.979 mm for men(p for trend=0.032), respectively. After adjustment for major cardiovascular risk factors, the relationship between CRP and carotid IMT was significant in women(p for trend=0.017), but not in men(p for trend=0.798). Similarly, adjusted odds ratio of increased IMT, defined as the sex-specific top quartile, for the highest versus lowest CRP quartiles was 1.55(95% CI=1.06-2.26) in women, but only 1.05(95% CI=0.69-1.62) in men. Conclusions : CRP and carotid IMT levels appear to be directly related in women, but not in men.

Purpose: The purpose of this study was to examine the mediating effect of regimen distress in the relationship between medication adherence and glycemic control in men with type 2 diabetes. Methods: A total of 116 patients with type 2 diabetes was recruited for the cross-sectional survey design. Data were analyzed using descriptive statistics, independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression using Baron and Kenny steps for mediation. Results: The mean score for medication adherence was 6.32, and the mean glycemic control level (HbA1c) was 7.47%. The mean score was 2.37 for regimen distress. There were significant correlations among medication adherence, regimen distress, and HbA1c. Regimen distress had a partial mediating effect (${\beta}$=.22, p=.005) in the relationship between medication adherence and HbA1c (Sobel test: Z=2.47, p=.013). Conclusion: Regimen distress was found to be associated with glycemic control in men with type 2 diabetes. Based on the findings of this study, nursing intervention programs focusing on decreasing regimen distress are highly recommended to improve level of glycemic control in patients with type 2 diabetes.

The purpose of this study was to assess the zinc and copper status of type 2 diabetic women and to analyse the relation-ship among zinc and copper status, and diabetic control indices of diabetes. The mean age of diabetes was 57.9 years old. The mean duration of diabetes was 8.0 $\pm$ 6.5 years. The mean daily energy intake of diabetes was 1562 kcal. There were no significant differences of age, BMI, %body fat, nutritional intakes, total energy intake, and energy composition from carbohydrate, protein, and fat between diabetes (n = 50) and control group (n = 68). However, both zinc intake density (4.15 mg/1000 kcal) and zinc %RDA (62.0%) of diabetes were significantly lower than control group (p <0.05, P < 0.01, respectively). The plasma zinc level was not significantly different between diabetes and control group (90$\mu$g/dl, 91$\mu$g/dl respectively). The proportion of diabetic women whose plasma zinc levels were lower than 76 $\mu$g/dl(borderline zinc deficiency) was 18.8%. This was about 38% higher than control group. It has been suggested that insulin secretion might decrease in borderline plasma zinc and copper deficiency and increase in normal plasma zinc and copper status. The urinary zinc excretion was twice higher in diabetes than in control group (p < 0.001). The urinary zinc loss was positively correlated with the duration of diabetes (p < 0.05), hyperglycemia (p < 0.001) and insulin resistance (p < 0.05). These results lead us to conclude that normal blood glucose level controlled by diet therapy could improve the hyperzincuria in diabetic women.

Mangosteen peel extract is a xanthone group, that plays an important role in anti-angiogenesis. This study investigated mangosteen peel extract on cerebral neovascularization in type 2 diabetes mellitus (DM) rats. This study used 36 rats, randomized into six groups: C1 (negative control); C2 (high fat diet (HFD) and mangosteen peel extract at 200 mg/kg BW); C3 (HFD and diabetic); E1, E2, and E3 (HFD, diabetic, and extract at 100, 200, and 400 mg/kg BW respectively). All groups were measured body mass index (BMI), homeostasis model assessment-insulin resistance (HOMA-IR) and β cell function (HOMA-B), and histopathological feature of cerebral vascular (CV). There were significant differences in BMI, HOMA-IR, HOMA-B, and the mean number of CV (all p < 0.05) among treatment groups. E1-3 groups had a significantly lower level of blood glucose and HOMA-IR, and a higher level of HOMA-B and BMI (all p < 0.05) which tends to reduce cerebral neovascularization. HOMA-IR independently had a positive effect to induce neovascularization of CV (p < 0.05, R² = 26.8%). These findings suggested that mangosteen peel extract increased β-cell function sensitivity, and effectively suppressed insulin resistance, BMI, and cerebral neovascularization process in type 2 DM rats.

Ten, first lactation, 87.5%HF dairy cattle were used to investigate effects of long-term administration of recombinant bovine somatotropin (rbST) on nutrient uptake by the mammary gland at different stages of lactation. Measurements of arterial plasma concentrations and arterial-venous differences of metabolites across the mammary gland were performed in combination with measurment of mammary blood flow to estimate the mammary uptake. Animals in experimental groups were injected subcutaneously every 14 days from day 60 of lactation with a prolonged-release formulation of 500 mg of rbST (POSILAC, Monsanto, USA) or with sterile sesame oil without rbST in the control group. During early lactation, the milk yield of rbST-treated animals was higher than that of the control animals (p<0.05). The peak milk yield in both groups of animals declined from the early period of lactation with progression to mid- and late-lactation. No significant changes were observed in the concentration of milk lactose, while the concentrations of milk protein significantly increased as lactation advanced to mid- and late-lactation in both groups. Milk fat concentrations were significantly higher in rbST-treated animals than in control animals, particularly in early lactation (p<0.05). Mammary blood flow (MBF) markedly increased during rbST administration and was maintained at a high level throughout lactation. The mean arterial plasma concentrations for glucose and acetate of rbST-treated animals were unchanged. The net mammary glucose uptake of rbST-treated animals increased approximately 20% during early lactation, while it significantly decreased (p<0.05), including the arteriovenous differences (A-V differences) and extraction ratio across the mammary gland, as lactation advanced to mid- and late-lactation. A-V differences, mammary extraction and mammary uptake for acetate increased during rbST administration and were significantly higher (p<0.05) than in the control animals in early and mid-lactation. Mean arterial plasma concentrations for ${\beta}$-hydroxybutyrate and free glycerol were unchanged throughout the experimental periods in both groups. A-V differences and extraction ratio of ${\beta}$-hydroxybutyrate across the mammary gland did not alter during rbST administration. Mean arterial plasma concentrations for free fatty acids ($C_{16}$ to $C_{18}$), but not for triacylglycerol, increased in rbST-treated animals and were significantly higher than in control animals during early lactation (p<0.01). These findings suggest that an increase in MBF during rbST administration would not be a major determinant in the mediation of nutrient delivery and uptake by the mammary gland for increased milk production. Local changes in biosynthetic capacity within the mammary gland would be a factor in the utilization of substrates resulting in the rate of decline in milk yield with advancing lactation.

Purpose: The risk of cardiovascular disease (CVD) has been shown to be associated with systemic inflammation in obese adults with metabolic syndrome (MetS). The aims of this study were to evaluate the prevalence of MetS and its relation to inflammatory markers in obese Thai children. Methods: A cross-sectional study was conducted. Children with history of endogenous obesity, chronic diseases, drug ingestion, and any acute illness within 2 weeks prior to enrollment were excluded. Their fasting blood glucose (FBG) levels, oral glucose tolerance tests, insulin, lipid profiles, and selected inflammatory markers, including interleukin-6, tumor necrosis factor-alpha, and high-sensitivity C-reactive protein (hs-CRP) levels, were tested. Results: In this study, 58 obese Thai children (female, 20; male, 38) with a mean body mass index z score of $5.1{\pm}2.2$ were enrolled. The prevalence of MetS and prediabetes was 31% and 17.2%, respectively. None of the children had diabetes. FBG levels, 2-hour glucose levels, and lipid profiles were not statistically different between those with and without MetS. However, obese children with MetS had higher insulin levels and homeostasis model assessment of insulin resistance values. Elevated hs-CRP levels were found in 69% of the cases, although it was not statistically different between the 2 groups. Conclusion: We described a substantial prevalence of MetS in Thai obese children. Regardless of MetS status, two-thirds of the obese children had elevated hs-CRP level, indicating subtle ongoing inflammatory process. This chronic inflammation feasibly predisposes them to CVD in the future, even in children without MetS.

Since the 1960s, Korea has achieved rapid economic growth, longer life expectancy, accelerated urbanization and a westenization of diet. Cardiovascular disease has become the leading cause of death; however the prevalence of ischemic heart disease(IHD) remains low. A cross-sectional multiphasic screening service for 18,426 persons aged $30\sim64$ years in a Medical Aid Program in Kyonggi-do Province was conducted from 1991 to 1993. Total cholesterol(TC), fasting blood glucose(FBG), blood pressure(BP), and electrocardiographic(EKG) data were collected. The result as follows ; 1. On the EKG findings, the age-adjusted prevalence of myocardial ischemia and myocardial infarction was 1.45% in men and 2.06% in women. 2. The mean blood pressure was 122.9/78.8mmHg. The age-adjusted prevalence of hypertension was 11.05% in men and 9.02% in women. The prevalence of hypertension showed increasing tendency according to age increase. In all age group, the prevalence of hypertension was higher in men than women. 3. The mean total cholesterol level was 184.4mg/dl in men and 189.2mg/dl in women. The age-adjusted prevalence of hypercholesterolemia was 4.88% in men and 5.67% in women. The total cholesterol level showed increasing tendency according to age increase, except $55\sim64$ age group in men. 4. The prevalence of hyperglycemia is 5.8%. The age-adjusted prevalence of hyperglycemia is 6.72% in men and 4.50% in women. The prevalence of hyperglycemia showed increasing tendency according to age increase. 5. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension than normal, in all age group of men and women less than 40 years-old. Only in women more t]fan 40 years-old, the prevalence of myocardial ischemia and myocardial infarction was higher in hypercholesterolemia and hyperglycemia. Nevertheless there is not statistical association between ischemia heart disease and previous risk factors in other age group, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension, hypercholesterolemia and hyperglycemia than normal. The result of this study suggest that relationships between major risk factor of ischemic heart disease and ischemic heart disease is similar to existing theory.

In a 12-week experiment, the rock bream, Oplegnathus fasciatus, and olive flounder, Paralichthys olivaceus, were investigated to determine the effects of starvation on their physiological parameters. The protein and DNA contents of the starved fish were significantly higher than the initial values and those of the fed fish. The RNA contents and RNA/DNA ratios of the fed fish were significantly higher than those of the other groups (P<0.05). The hematocrit, hemoglobin, red blood cells (RBC), and mean corpuscular volume (MCV) of the fed rock bream were significantly higher than at baseline (P<0.05), whereas the mean corpuscular hemoglobin concentration (MCHC) of the fed fish was lower than at baseline (P<0.05). The hematocrit, hemoglobin, RBC, and MCHC of the starved group were significantly lower than the baseline values, whereas the MCV of the starved group was significantly higher than the baseline value (P<0.05). No significant difference in alanine aminotransferase was observed between the fed fish and baseline, whereas the starved fish value was significantly higher than the baseline value (P>0.05). There were no significant differences in cortisol levels. However, the glucose level in the fed group was significantly higher than the baseline level and that in the starved group was significantly lower than the baseline level (P<0.05).
