BACKGROUND
Glycosylated hemoglobin (HbA1c) is a useful index of mean blood glucose concentrations over the preceding 2 to 3 months. Elevated HbA1c levels (> 7%) are associated with a higher incidence of microvascular and macrovascular complications in patients with diabetes mellitus. However, the relationship between HbA1c and cardiovascualr disease risk in nondiabetic adults has been unclear. The aim of this study is to estimate the association of HbA1c with cardiovascular disease risk factors and metabolic syndrome in nondiabetic adults. METHODS: The subjects of this study included 533 adults (180 males and 353 females) aged 20~70 years (mean age: 46.9 +/- 10.12 years) without previously diagnosed diabetes who lived in Kangyang country. We examined baseline HbA1c levels and cardiovascular risk factors. Metabolic syndrome was defined based on International Diabetes Federation guidelines. RESULTS: The prevalence of metabolic syndrome significantly increased as HbA1c increased. HbA1c revealed a significant correlation with age (r = 0.258, P < 0.001), BMI (r = 0.152, P < 0.001), waist circumference (r = 0.252, P < 0.001), fasting plasma glucose (r = 0.319, P < 0.001), systolic (r = 0.100, P = 0.021), diastolic (r = 0.115, P = 0.008) blood pressure, total cholesterol (r = 0.232, P < 0.001), triglyceride (r = 0.156, P < 0.001), LDL cholesterol (r = 0.216, P < 0.001), and HDL cholesterol (r = -0.167, P < 0.001). Multiple regression analysis showed that HbA1c had a association with age, fasting plasma glucose, and dyslipidemia. The receiver operating characterstics (ROC) curve analysis determined HbA1c of 5.35% to yield optimal sensitivity and specificity corresponding to the presence of metabolic syndrome. CONCLUSION: The HbA1c level is correlated with cardiovascular risk factors and prevalence of metabolic syndrome in nondiabetic adults.

BACKGROUND
The criteria for the diagnosis of diabetes mellitus have been modified by the American Diabetes Association (ADA) in 1997. The ADA proposed that the diagnosis of diabetes be defined by a fasting plasma glucose (FPG) of 7.0 mmol/L. Disagreement has been reported between criteria based on FPG and postchallenge 2-h plasma glucose (2-h PG). The aim of the present study is to assess the FPG criteria as the diagnostic screening test for diabetes in Korean middle-aged adults in comparison to the 2-h PG criteria. METHODS: Randomly selected 1,731 subjects (679 men and 1,052 women) aged 40~70 years (mean age: 58.4 +/- 7.89 years) without previously diagnosed diabetes completed 75 g oral glucose tolerance test (OGTT). We assessed the prevalence of diabetes mellitus and the level of agreement (kappa statistics) according to the different diagnostic glucose categories. RESULTS: The frequency of newly diagnosed diabetes was 2.7% (n = 51) using the FPG criteria only; 6.4% (n = 120) using the 2-h PG criteria only; and 6.9% (n = 130) using concentrations of > or = 7.0 mmol/L for FPG or > or = 11.1 mmol/L for 2-h PG. Of the 120 subjects with diabetes by the 2-h PG criteria, 65.8% (n = 79) were not diagnosed with diabetes according to FPG concentration. The level of agreement between two diagnostic criteria was low (kappa = 0.268). The receiver operating characterstic (ROC) curve analysis determined FPG of 5.6 mmol/L to yield optimal sensitivity and specificity corresponding to 2-h PG 11.1 mmol/L. CONCLUSION: The findings in this study demonstrate that the discordance between the FPG and 2-h PG criteria in the diagnosis of diabetes in Korean middle-aged adults is large. We suggest that IFG group (FPG 5.6~6.9 mmol/L) were performed 75 g OGTT for diagnosing diabetes mellitus in Korean middle-aged adults.

AbstractAbstract PDF
BACKGROUND
Gluconeogenesis is strongly stimulated during fasting and is aberrantly activated in diabetes mellitus. PPARgamma-coactivator 1 (PGC-1) and Peroxisome proliferator -activated receptors (PPARs) costimulate the expression of key enzymes of gluconeogenetic pathway. This study was performed to evaluate the response to dietary caloric restriction (CR) on the PPARs and PGC-1 expression in liver of diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats. METHODS: Diabetic OLETF rats (male, 24 weeks) and Long-Evans Tokushima Otsuka (LETO) rats (male, 24 weeks) were used in this study. Liver PPARs and PGC-1 mRNA, and blood glucose levels were investigated at 1, 2, and 3 weeks after the beginning of 30% CR. PPARs and PGC-1 mRNA were determined by RT-PCR and blood glucose levels were measured by spectrophotometric assay. RESULTS: The liver PGC-1 mRNA expressions were increased to 19% in non-diabetic LETO rats but significant change was not observed in diabetic OLETF rats by 30% CR. The liver PPARgamma mRNA expressions were not changed in non-diabetic LETO rats but increased to 23% in diabetic OLETF rats by 30% CR. The difference of PPARalpha and PPARbeta mRNA expressions in liver of OLETF and LETO rats were not observed. CONCLUSION: The liver PPARgamma and PGC-1 expression response to CR are altered in OLETF rats compared to in LETO rats. These findings suggested that PPARgamma and PGC-1 expression control system altered in diabetic OLETF rat liver and altered PPARgamma and PCG-1 expression may some roles on the aberrantly activated gluconeogenesis in diabetes mellitus.

BACKGROUND
To investigate the effects of high glucose on oxidative stress of islet beta cells, the effects of high glucose on antioxidant enzymes, the production of free reactive substances and paraquat-induced cytotoxicity were examined in cultured mouse insulinoma cells (MIN6N8a). METHODS: The MIN6N8a cell line (Obtained from Diabetic research center, Univer sity of Calgary, Canada) was maintained in RPMI1640 medium supplemented with 10% fetal bovine serum, at 37degrees C under an atmosphere of 5% CO2 and 100 % humidity. The MIN6N8a cells were cultured in high glucose (22.4 mM) and normogl-ucose (5.6 mM) containing RPMI1640 media, for 1-6 days, and the superoxide dismutase (SOD), catalase and glutathione peroxidase (GSHPx) activities in the MIN6N8a cells assayed. The levels of reactive oxygen species in the MIN6N8a cells was determined using dihydroethidium (DHE). Paraquatinduced cytotoxicity was determined using the 3-[4,5-dimethylthiazol-2-yl]-2, 5diphenyl tetraz olium bromide (MTT) method. RESULTS: No difference was observed catalase in the catalase and GSHPx activities in MIN6N8a cells between the high glucose (22.4 mM) and normoglucose (5.6 mM) groups. The CuZn-SOD activity of MIN6N8a cells was decreased by 32% in the high glucose (25.4 mM) medium compared to normoglucose (5.6 mM) medium, while the Mn-SOD activity was increased by 24% in high glucose group. The paraquat induced cytotoxicity of MIN6N8a cells was potentiated by high glucose. and the amount of DHE oxidation increased. CONCLUSION: The Oxidative stress in MIN6N8a cells was increased by high glucose as a resulted of the decreased CuZn-SOD activity and increased production of reactive oxygen species. Increased oxidative stress in MIN6N8a cells by high glucose may play some roles in the pathogenesis of diabetes.
