  • Once it is diagnosed, immediate surgical extirpation is desirable for treating left ventricle myxoma that's accompanied with stenosis of the left ventricle outflow tract. This is because this condition may potentially induce fatal complications such as cerebral infarction or myocardial infarction that's triggered by myxoma embolus, or even sudden death due to coronary malperfusion. An 18-year-old male with the chief complaint of NYHA class II exertional dyspnea was found to have a $4{\times}3\;cm^2$ sized mass on transthoracic ultrasonography, which was shown to move down the left ventricle outflow tract on the systolic phase. The mass was immediately extirpated by incision of the left ventricle; the mass was finally diagnosed as a myxoma. The patient was discharged on at the 10th day postoperatively without any complications. On the 22-month follow-up observation made at the out-patient clinic after discharge, there have been no noticeable, significant changes seen on physical examination or the cardiac ultrasonography.

  • We report here on the midterm results after a Starnes operation for a severely symptomatic neonate with Ebstein's anomaly. A one-day-old baby presented with cyanosis and severe cardiomegaly. We peformed patch closure of the tricuspid valve with a central shunt after failure of tricuspid valve repair with vertical plication of the atrialized ventricle at her age of 19 days. The coronary sinus was drained into the right ventricle. She underwent bidirectional cavopulmonary shunt and extracardiac conduit Fontan operation at her age of 16 and 30 months, respectively. She is now 56 months old and is doing very well. The recent follow-up study revealed that she was in normal sinus rhythm and had a normal sized left ventricle with good function and the small right ventricle without thrombus formation.

  • Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (<50 mg/dL, n=20), medium HDL-cholesterol (50 $\leq$, < 60 mg/dL, n=39) high serum HDL-cholesterol groups (60 $\leq$ mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate: protein: fat was 57:15:28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.

  • ABSTRACT - To examine antihypertensive components of Ganoderma lucidum in Korea, two kinds of fruiting bodies (J and K) were used for extraction with water and the extracts were purified by ethanol precipitation and dialysis. Three fractions, i.e., the aqueous total extract(A), the ethanol supernatant(B} and the purified precipitate(C), were compared for antihypertensive activity in anesthetized spontaneously hypertensive rats (SUR). Although fractions A and B showed the activity, fraction C did not. Particularly, fraction B of sample K produced 44.3% reduction in diastolic blood pressure and 30.6% reduction in heart rate after i.v. administration of a dose of 10 mg/kg. Direct effects of this fraction B to the heart were observed in the isolated blood perfused heart preparation of the dog. It induced positive chronotropic and inotropic responses dose-dependently in the case of sample J. In the case of sample K, marked chronotropic and inotropic effects on atrial muscle but not on ventricular muscle were induced. In both samples, coronary blood flow (CBF) was dose-relatedly increased.reased.

  • Objectives: Myocardial reperfusion is the only logical cure for ischemic heart disease. However, ischemic-reperfusion (I/R) injury is one of the underlying factors facilitating and accelerating the apoptosis in the myocardium. This study set to investigate the impact of Teucrium polium (TP) hydro-alcoholic extract on I/R induced apoptosis in the isolated rat heart. Methods: Isolated rat hearts were classified into six groups. The control samples were subjected to 80 min of perfusion with Krebs-Henseleit bicarbonate (KHB) buffer; in control-ischemia group, after primary perfusion (20 min) the hearts were exposed to global ischemia (20 min) and reperfusion (40 min). Pretreated groups were perfused with $500{\mu}M$ of vitamin C and various TP concentrations (0.5, 1, 2 mg/ml) for 20 min, and then the hearts were exposed to ischemia and reperfusion for 20 min and 40 min, respectively. Cardiodynamic parameters including rate pressure product (RPP), heart rate (HR), the maximum up/down rate of left ventricular pressure (${\pm}dp/dt$), left ventricular developed pressure (LVDP), and coronary artery flow (CF) were achieved from Lab Chart software data. The Bax and BCl-2 gene expressions were measured in heart samples. Results: Hearts treated with TP extract and vit C represented a meaningful improvement in cardiac contractile function and CF. The overexpression of Bcl-2, downregulation of Bax, and improvement of apoptotic index (Bax/Bcl-2) were observed in pretreated TP extract and vit C hearts. Conclusion: The TP extract was found to ameliorate the cardiac function in the reperfused myocardium. Also, it can hinder apoptotic pathways causing cardioprotection.

  • Dual drug-eluting stents (DES) is a primary treatment method for coronary arterial diseases in current interventional cardiology practice. However, their pathological results according to the sequence of coating of drugs have not been reported yet. The peptide-dopamine dissolved in acetonitrile was coated onto the Chonnam National University Hospital (CNUH) stent using an electrospinning coating machine. For secondary coating (e.g., sirolimus coating, designated as SPS), sirolimus (SRL) and poly lactic-glycolic acid (PLGA) were mixed in tetrahydrofuran (THF), and the solution was then coated on the CNUH stent that had underwent the primary peptide coating using an electrospinning and spray technique. Next, the peptide-dopamine was coated on the SRL-PLGA coated stent (PSS). In this study, it was confirmed that endothelialization was promoted without being significantly affected by the coating order (SPS or PSS). The sequence of drug and peptide coating may affect the development of restenosis and PSS was effective in the prevention of restenosis compared to that of using SPS.

  • Familial concordance of vascular risk factors is well understood and there are many studies about inter-spouse concordance of the risk factors for coronary heart disease. However, there are no studies for inter-spousal relation of the risk factors in cerebrovascular disease patients. We analysed inter-spouse correlation of cerebrovascular risk factors in patients admitted our hospital due to stroke and their spouses. There was statistically significant inter-spouse concordance in the presence of hypertension(p=0.025) and carotid IMT(r=0.479, p=0.001). However, the further age-adjusted analysis revealed no significant result. Differently from the results of previous studie,, the present study shows no significant spousal concordance. Althought there are tendencies of spousal concordance in some risk factors, the age is major determinant.

  • Purpose: The main purpose of this study was to describe the relationship of mothers' parenting attitude as perceived by the child to self-esteem, and school adjustment of school age children with Tetrology of Fallot (TOF). Methods: In this study a self-administered questionnaire survey was used to collect the data. The participants included 38 children who were registered in a pediatric cardiology clinic in one tertiary medical center. Their ages were between 11 and 15 years. They were diagnosed with TOF, and had no other congenital problems. Data were collected from November 1 to November 30, 2009. After obtaining telephone consent from the mothers and children, questionnaires were mailed to 64 participants and 38 questionnaires were returned. Data were analyzed using Statistical Package for the Social Sciences (SPSS) WIN 15.0 version. Results: There was a significant correlation between perceived parenting attitude, self-esteem, and school adjustment of children with TOF. Conclusion: Children who perceive their mothers' parenting attitude to be more positive also report higher self-esteem and better school adjustment. These findings are similar to other studies done with healthy school age children. However, parents of children with TOF may require different parenting approaches to foster positive self-esteem and school adjustment.

  • KR-1008 and KR-30006 are 1,4-dihydropyridine derivatives, new vasodilatory calcium antagonists from KRICT. Calcium antagonistic properties of the compounds were studied in the isolated heart (Langendorff preparation), pulmonary artery (vasodilation), and in the papillary muscle (negative inotropic effect) of the guinea pig. Antihypertensive effect were also investigated after i.v. or oral administration in the SHR (spontaneously hypertensive rat). They produced a sigificant inhibition of Ca-induced contraction in the guinea pig pulmonary artery at the concentrations of above $10^{-8}M$. The negative inotropic effect of the electrically stimulated papillary muscle appeared from the concentration of $10^{-6}M$, which is about hundred times higer than the concentration of vasodilation effect. Left ventricular pressure also decreased from the concentration of $3\;{\times}\;10^{-6}M$ in KR-1008 and KR-3006 in the Langendorff heart preparations. Coronary flow rate increased from $10^{-6}M$ in KR-1008 and nicardipine and appeared no change in KR-30006. The antihypertensive effect of KR-1008 (EC 20: $2.9\;{\mu}g/kg$) was potent more than nicardipine (EC 20: $3.4\;{\mu}g/kg$) and than Kr-30006 (EC 20: $6.8\;{\mu}g/kg$) was, after i.v. bolus injection in the anesthetized SHR. The antihypertensive effect in the conscious SHR appeared 30 minutes after oral administration of 10 mg/kg and persisted 4 hrs in KR-1008 and 12 hrs in KR-30006. Heart rate tended to increase for 0.5-1 hr after oral administration of the test compounds.

  • Procainamide is the drug of second choice (after lidocaine) in most coronary care units for the treatment of sustained ventricular arrhythmias associated with acute myocardial infarction. The purpose of this study was to develop the efficient assay method of procainamide in human plasma and to assess the pharmacokinetic profile of procainamide in healthy Korean volunteers. The pharmacokinetics of procainamide administered orally was evaluated after a dose of 250 mg. Procainamide in plasma was assayed using a specific HPLC method with UV absorbance at 275 nm. AUC was $4.58{\pm}0.90 {\mu}g/ml-hr$, $C_{max}\;1.34{\pm}0.39{\mu}g/ml$, $T_{max}\;1.06{\pm}0.34 hr$ and half-life $3.07\pm0.34 hr$. $T_{max}$ was slightly shorter than that in Caucasian (1-2 hr), whereas the half-life was similar to that in Caucasian (2.5-4.1 hr).
