OBJECTIVES: This study was designed to investigate the association between Ser311/Cys311 polymorphism in the dopamine D2 receptor gene and bipolar disorder in korean population. METHOD: Ser311/Cys311 polymorphism in the dopamine D2 receptor gene was typed with PCR in 86 bipolar disorders and 100 normal controls. RESULTS: Genotype of Ser/Ser, Ser/Cys, Cys/Cys were 82 (95.3%), 4 (4.7%), 0 (0.0%) respectively in the bipolar disorders, 96 (96.0%), 4 (4.0%), 0 (0.0%) respectively in the controls. Allele frequencies of Ser and Cys were 168 (97.7%), 4 (2.3%) in the bipolar disorders, 196 (98.0%), 4 (2.0%) in the controls. There were no differencies in genotype distribution and allele frequencies of dopamine D2 receptor gene polymorphism Ser311/Cys311 between in the bipolar disorders and in the controls. CONCLUSION: These result suggests dopamine D2 receptor gene polymorphism Ser311/Cys311 is not causally related to the development of bipolar disorder in korean population.

2.Lesion Characteristics in Patients with Acute Coronary Syndrome: A Comparison with Lesion in Patients with Stable Angina by Intravascular Ultrasound.
Korean Circulation Journal 2004;34(6):548-557
BACKGROUND AND OBJECTIVES: The pathophysiology of acute coronary syndrome (ACS) is plaque rupture with thrombus formation, which is different from that of stable angina pectoris (SA). Intravascular ultrasound (IVUS) prior to percutaneous coronary intervention provides information on the plaques and vessel wall itself. The purpose of this study was to evaluate the lesion characteristics of ACS prior to coronary intervention compared to those of SA lesions by IVUS. SUBJECTS AND METHODS: Pre-interventional IVUS was performed on 68 culprit lesions in 41 ACS and 25 SA patients. The plaque morphology, lumen and vessel sizes, and arterial remodeling pattern at the lesion segment were analyzed in both groups. A plaque rupture was defined as a plaque containing a cavity that communicated with the lumen, which was covered with a fibrous cap. RESULTS: Positive remodeling was more frequent in patients with ACS than those with SA (42 vs. 11%), whereas negative remodeling was more frequent in patients with SA (22 vs. 41%) (p=0.023). Plaque rupture/dissection and thrombus was more frequent (51 vs. 19%, p=0.006 and 39 vs. 4%, p=0.001) in patients with ACS. Lesions with ACS had significantly larger EEM CSA, plaque CSA and plaque burden (p<0.05). There were no significant differences in the clinical parameters, angiographic parameters and plaque morphologies. CONCLUSION: Positive remodeling, plaque rupture/dissection and thrombus were more frequently observed in patients with ACS. In addition, lesions with ACS had a larger vessel size and a higher plaque burden. The type of remodeling, plaque rupture or dissection, thrombus and amount of plaques might have an impact on the clinical presentation.

Maffucci's syndrome is a congenital, non-hereditary mesodermal d splasia manifested by multiple enchondromas and hemangiomas. Several case reports and reviews indicate that there is a tendency toward malignant transformation of the enchondroma. The incidence of malignancy may be as high as 30%. We report a case of 10-year-old female with multiple hemangiomas on the face, palms, and soles and skeletal chondromatoses of the multiple bones.

BACKGROUND: Interleukin-2 receptor (IL-2) is expressed and released predominantly activated T lymphocyte. Increased serum levels of soluble IL-2R have been noted in a variety of autoimmune diseases and in conditions associated with T lymphocyte activation. OBJECTIVE: We aimed to examine whether the T lymphocyte activation has any association with the pathogenesis of Behçet's disease. METHOD: We have measured the serum level of soluble IL-2R in serum samples obtained from 67 patients with Behçet's disease and 30 healthy people as a control group, using a double-antibody sandwich enzyme-linked immunosorbent assay technique. RESULTS: Serum soluble IL-2R levels were found to be significantly elevated in the group of Behçet's disease as compared with the control group. No significant differences were found within clinical subtypes of Behçet's disease. CONCLUSION: These findings suggest the presence of an ongoing T lymphocyte activation in this disease process.

BACKGROUND: Osteoporosis or osteopenia has been reported in patients taking antiepileptic drugs, but the precise pathophysiological mechanisms of these abnormalities are unclear. The aim of this study was to assess the relationship of antiepileptic drugs on bone mass by analyzing bone mineral density (BMD). METHODS: We compared 62 epileptic women on long-term antiepileptic therapy the same number of age and weight matched healthy control subjects. We measured the serum calcium, phosphorus, protein, alkaline phosphatase and osteocalcin for analyzing factors, that have an influence on bone metabolism and BMD. BMD was measured on the lumbar spine by dual-energy X-ray absorptiometry. RESULTS: The serum level of calcium and osteocalcin were not different between the groups. The serum level of phosphorus and protein were significantly lower in the patient group compared to their controls. The serum level of alkaline phosphatase was significantly higher in the patient group than in their controls. The BMD was significantly lower in the patient group than in their controls. There was a significant correlation between the BMD and the duration of therapy in the patient group. CONCLUSION: The long-term use of antiepileptic drugs leads to a decreased BMD, and the degree of bone mineral density was related to the duration of the therapeutic use of antiepileptics.

BACKGROUND: Mitral regurgitation is a valvular heart disease that produce complex hemodynamic alternations and myocardial dysfunction occurs subclinically, so result in a high incidence of left ventricular dysfunction that might affect postoperative result. In order to assess preoperative factors affecting the outcome of mitral valve replacement in patients with chronic mitral regurgitaion, we evaluated prognostic factors from preoperative clinical, laboratory, and echocardiographic findings in 71 patients with chronic mitral regurgitation who received mitral valve replacement. METHODS: From 1985 to 1994, 71 patients with chronic mitral regurgitation, who received mitral valve replacement, were included in this study. The patients were defined as group I who had improved symptom and / or decreased left ventricular end-diastolic dimension after operation, and group II who had persistent symptom and / or over 60mm of left ventricular end-diastolic dimension after operation. RESULTS: 1) In clinical findings, preoperative systolic blood pressure was higher in Group I patients(p<0.05). 2) Hemoglobin, serum creatinine, and blood urea nitrogen level were not significantly different in both groups. 3) In echocardigraphic findings, left atrial dimension, left ventricular end-systolic / end-diastolic dimension, and left ventricular volume index of Group II were much higher than those of Group I patients(p<0.05). 4) In the discriminant analysis, left ventricular end-diastolic dimension, age, NYHA functional class, and left ventricular mass index were defined as important prognostic factors. CONCLUSION: According to the above results, preoperative age, NYHA functional class are significant prognostic factors in clinical and laboratory findings. And left atrial dimension, left ventricular end-systolic and end-diastolic dimensions, left ventricular volume index, and left ventricular mass index are significant prognostic factors in echocardiographic findings.

9.Determination of Safe Contrast Media Dosage to Estimated Glomerular Filtration Rate Ratios to Avoid Contrast-Induced Nephropathy After Elective Percutaneous Coronary Intervention.
Korean Circulation Journal 2011;41(5):265-271
BACKGROUND AND OBJECTIVES: To avoid the risk of developing contrast-induced nephropathy (CIN), it has been suggested that patients be subjected to a minimal necessary dose of contrast medium (CM-dose). However, often it is not easy to determine such a dose. This study assessed the usefulness of the ratio of CM-dose to estimated glomerular filtration rate (eGFR) in predicting the risks of CIN and sought to determine the safe level of CM-dose/eGFR in patients undergoing non-emergent percutaneous coronary intervention (PCI). SUBJECTS AND METHODS: We enrolled a total of 226 patients and calculated the ratio of CM-dose using grams of iodine (g-I) to eGFR, thus expressing it as g-I/eGFR. Among the CIN patients, those with ne-phropathy requiring dialysis (NRD) were also evaluated. RESULTS: Overall, there were 16 cases (7.1%) of CIN. On univariate and multivariate regression analysis, g-I/eGFR alone was found to be an independent predictor for CIN (hazard ratio=10.73, p<0.001). In an receiver operating characteristic analysis, fair discrimination for CIN was found at a g-I/eGFR level of 1.42 (C statics=0.867), and at this value, the sensitivity and specificity were 81.3% and 80%, respectively. Of patients (n=51) with g-I/eGFR > or =1.42, 23.6% (13/51) and 7.8% (4/51) developed, while those with g-I/eGFR <1.42 (n=171) had a lower incidences of CIN (1.8%, 2/171, p<0.001) and NRD (0%, 0/171, p<0.001). CONCLUSION: It can be concluded that a g-I/eGFR <1.42 is a simple, useful indicator for determining the safe CM-dose based on the pre-PCI eGFR values. Furthermore, g-I/eGFR might have a close relationship with the development of NRD as well as CIN.

BACKGROUND: It was recently shown that human atherosclerotic plaque contains large numbers of T lymphocytes : this indicates that immune and inflammatory mechanism may be important factors in the pathogenesis of atherosclerosis. By measuring the soluble interleukin 2 receptor(sIL-2R) level we can evaluate the activation of T lymphocyte. The purpose of this study is to evaluate relationship between T cell activation and ischemic heart disease by measuring the soluble interleukin 2 receptor (sIL-2R) level in patient with ischemic heart disease. METHOD: Seventy-two patients(40 males and 32 female, mean age : 56.5+/-9.9 years) who were taken coronary angiography were included in this study. Among them, 49 patients showed abnormal coronary angiographic findings and 23 patients showed normal coronary angiographic findings. Ten mililiters of arterial blood was drawn at the time of coronary angiography. The blood was allowed to coagulate and then the serum was removed and tested in duplicate for soluble interleukin 2 receptor (sIL-2R) level by ELISA. RESULTS: 1) The soluble interleukin 2 receptor (sIL-2R) level was significantly different between abnormal coronary angiographic findings and normal coronary angiographic findings (P < 0.001). 2) According to clinical severity of ischemic heart disease (i.e. stable angina, unstable angina, acute myocardial infarction.), soluble interleukin 2 receptor (sIL-2R) level was not significantly different between single vessel disease group and multivessels disease groups (p > 0.05), but showed increasing tendency with clinical severity. 3) According to numbers of involved coronary vessels, soluble interleukin 2 receptor (sIL-2R) level was not significantly different between single vessel disease group and multivessels disease groups (p > 0.05). CONCLUSION: T lymphocyte activation, as reflected in elevated soluble interlekin 2 receptor (sIL-2R) level, is frequent in patient with ischemic heart disease. In the further we will investigate relationship between clinical diagnosis of ischemic heart disease of the numbers of involved coronary vessels and T cell activation.
