BACKGROUND
A recently discovered adipokine, retinol-binding protein-4 (RBP-4), is reportedly associated with insulin resistance and metabolic syndrome. This study was performed to analyze the relationship between serum RBP-4 levels and coronary artery disease (CAD) in Korean adults. METHODS: In 235 subjects (mean age 58 years) in whom coronary artery angiograms were performed due to complaints of chest pain, serum RBP-4 levels were measured by enzyme-linked immunosorbent assay. Coronary artery angiograms were performed in all subjects and the severity of CAD was assessed by the number of stenotic vessels. The presence of metabolic syndrome was defined by AHA/NHLBI criteria with body mass index substituted for waist circumference. RESULTS: Coronary angiogram showed that 101 subjects (43%) had normal coronary vessel, 82 subjects (34.9%) had 1-vessel disease, 31 subjects (13.2%) had 2-vessel disease and 21 subjects (8.9%) had 3-vessel disease. Subjects with coronary artery stenosis showed a higher mean age (60.5 +/- 10.0 years), fasting glucose (123.3 mg +/- 45.0 mg/dL) and lower mean value for high-density lipoprotein cholesterol (HDL-C) level (49.0 +/- 13.2 mg/dL), although serum RBP-4 levels were not significantly different between those with and without CAD. Mean age and fasting glucose level increased significantly as the number of stenotic vessels increased, although serum RBP4 level showed no significant differences among the different groups. Among the metabolic parameters, only serum triglyceride levels showed a significant correlation with serum RBP-4 levels. CONCLUSION: There was no difference in mean serum RBP-4 levels between subjects with or without coronary artery disease in Korean adults. Further studies are warranted to draw a clear conclusion on the effect of RBP-4 on atherosclerosis.

BACKGROUND
PPAR-gamma, a member of nuclear family, which is involved in the differentiation of adipose tissue, is reported to be associated in the pathogenesis of type 2 diabetes mellitus, insulin resistance and atherosclerosis. We conducted a research to see whether the prevalence of coronary artery disease is associated with Pro12Ala polymorphism in exon B of PPAR-gamma in Korean adults. METHODS: The study was conducted in 161 subjects (97 males, 64 females, mean age 57 year old) who underwent coronary angiogram due to chest pain. We assessed cardiovascular risk factors in all subjects, such as blood pressure, body mass index (BMI), fasting blood sugar and serum lipid profiles. Subjects were divided into four groups as normal, 1-vessel, 2-vessel and 3-vessel disease according to the number of stenosed coronary arteries. Genotypings of Pro12Ala polymorphism were done with Real-time polymerase chain reaction. RESULTS: Allelic frequency for proline was 0.957 and 0.043 for alanine, and they were in compliance with Hardy-Weinberg equilibrium (P = 0.85). 79 subjects (43.5%) had normal coronary artery, 52 subjects (31%), 1-vessel disease, 24 subjects (14.9%), 2-vessel disease and 15 subjects (9.3%), 3-vessel disease. When the cardiovascular risk factors were compared among these four groups, there were no meaningful differences except the age and high-density lipoprotein cholesterol levels, which were lost after adjustment for age and BMI. There were no significant differences in the prevalence or severity of coronary artery diseases according to the different genotypes of Pro12Ala polymorphism. CONCLUSIONS: There was no significantassociation between Pro12Ala polymorphism in exon B of PPAR-gamma and prevalence or severity of coronary artery disease in Korean adults. It is considered that further studies on the correlation between Pro12Ala polymorphism and coronary artery disease should be carried out in larger Korean population in the future

BACKGROUND
Thanks to ambulatory 24-h blood pressure monitoring device, it became possible to investigate circadian pressure rhythm under variable physiologic and pathologic conditions. Moreover, ambulatory 24-h blood pressure has allowed us to detect in diabetic patients unsuspected abnormalities of the blood pressure circadian rhythm and to relate them to autonomic or renal dysfunction. This study was designed to evaluate the relationship between circadian rhythm of mean blood pressure (MBP) and microvascular complications in patients with noninsulin-dependent diabetes mellitus (NIDDM). METHODS: 24hr blood pressure monitoring was applied to 63 normotensive NIDDM patients(mean age 55.3+7.2 year, male: 35, female: 28) who have been hospitalized at our hospital from March 1993 to December 1994 to measure systolic, diastolic and hourly mean pressure of daytime, night time and 24hr. In addition, NIDDM patients were divided into 2 groups according to 24 hour circadian blood pressure rhythm by measuring hourly mean pressure. These 2 groups, group 1 who had a circadian MBP rhythm, with a peak value in the afternoon and group 2 who had an absent or reversed circadian rhythm with a peak value during the night time, were observed to evaluate the frequency of diabetic microvascular complication. RESULTS: The mean systolic and diastolic ambulatory BP values were significantly higher in the group 2 NIDDM during night-time compared with control group and group 1(systolic pressure: F=12.53 p<0.05 diastolic pressure: F:=15.159 p<0.05). Although there was no significant differences in day-time heart rate between three groups, 1 and 2 group showed significant higher level of night-time heart rate comparing with that of control group (F=3.444 p<0.05). Group 2 diabetes patients showed, both systolic and diastolic, higher night-time and day-time blood pressure ratio(systolic pressure: F=35.958 p<0.05> diastolic pressure F=40.126 p<0.05). Observing the night-time and day-time heart rate ratio, group 1 and 2 patients showed significantly higher level compared with that of cantrol group(F=12.144 p<0.05). Regarding the retmopathy, group 1 patient.; showed mild degree retinopathy or normal finding(X =3.65 p<0.05). However, many group 2 patients showed moderate 2 degree nonproliferative retinopathy(X =3.23 p<0.05). The prevalence of overt nepkuopathy (24-hour urine protein>500mg) and autonomic neuropathy (postural and abnormal E:I ratio during deep breathing test) was significantly higher in group 2 (overt nephropathy: X'=3.23 p

BACKGROUND
It has been reported that QTc interval and QT dispersion prolongation on 12 lead EKG reflects predictability and diagnosis of cardiovascular complications induced by autonomic nervous system abnormalities. We have investigated in NIDDM patients whether severity of cadiovascular autonomic neuropathy(CAN) evaluated by conventional standard cardiovascular autonomic function test is correlated with prolongation of QT, QTc interval and QT dispersion. In addition, whether these prolonagtion can reflect CAN and if any other clinical variables related to pralongatian exist. METHODS: Eighty patients(39 male, 41 female) treated with oral hypoglycemic agents or insulin after diagnosis of NIDDM in our hospital were included in the study. These patients were devided into three groups (Group I, 13 subjects: No CAN, Group II, 20 subjects: Borderline CAN, Group III, 47 subjects: Definite CAN) according to the score of standard catdiovascular autonomic function test(Deep breathing test, Lying to standing test, Heart ration on Valsalva manuever, Postural BP drop test). The measured QT, QTc interval and QT disp rsion of eaeh diabetic group and control group were analyzed. RESULTS: l. Statistically significant prolongation of QT,QTc, QT dispersion was observed in NIDDM tients as compared with those of control group(p=0.015, 0,021, 0.001). 2. Severity of autonomic neuropathy has shown positive correlation with only prolongation of QT dispersion(p<0.05) in three diabetic subgroups. 3. Statistically significant difference was not ob::rved in HbAlc and BMI between each patients groups of NIDDM(p>0.05) but both HbAlc and BMI showed weak positive correlation with prologation of QT dispersion(r=0.262, r=0.267 repectively). CONCLUSION: QTc interval and QT dispersion are considered easily accessible factors to predict and evaluate the degree of cardiovascular autonomic function abnormalities in NIDDM patients, yet further long term follow up and study in large group should be carried out to decide if these factor can predict and reflect severity of cardiovascular abnormalities such as ventricular arrhythmia, and sudden cardiac death. In additian, prolonged QT dispersion has shown weak positive correlation with both HbAlc and BMI and some other influential factors are suggested to play a role in autonomic neuropathy in NIDDM patients.
