CXCR3 is a C-X-C chemokine receptor type 3 also known as GPR9 and CD183. CXCR3 is a G-Protein coupled chemokine receptor which interacts with three endogenous interferon inducible chemokine's (CXCL9, CXCL10 and CXCL11) and is proved to play a vital role in the Th1 inflammatory responses. CXCR3 has been implicated to be associated with various disease conditions like inflammatory diseases, autoimmune diseases, type I diabetes and acute cardiac allograft rejection. Therefore CXCR3 receptor is found to be an attractive therapeutic target for the treatment of inflammatory diseases. Inorder to decipher the biological function of a CXCR3, 3D structure is of much important but the crystal structure for CXCR3 has not yet been resolved. Hence, in the current study Homology modeling of CXCR3 was performed against various templates and validated using different parameters to suggest the best model for CXCR3. The reported best model can be used for further studies such as docking to identify the important binding site residues.

Recent advances in the surgical treatment of congenital disorders of the heart have necessitated an accurate preoperative diagnosis. Right heart catheterization has become widely accepted as a research tool and diagnostic test to detect the heart diseases, especially in the congenital heart anomalies. Right heart catheterizations were carried out in 50 cases of congenital heart diseases at Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, during the period of June, 1975 through September 1978. In age distribution, 27cases were below 10 years of age, 18 cases between 11 and 20, and 5 cases above 20 male to female ratio was 2.8:1. The distribution of congenital heart diseases was VSD [42%], TOF [36%], PDA [10%], ASD [8%], and PS[4%]. Of these, 44 cases [88%], were compatible with the clinical impressions that were made preliminarily before cardiac catheterization, and all the cases except 1 case of VSD was correlated well with the postoperative diagnosis. The right heart catheterization is considered to be reliable and accurate toll in the preoperative diagnosis of congenital heart diseases. These procedures caused complications such as left side hemiplegia [lcase], occlusion of the femoral artery [lcase], and transient ventricular tachycardia [1case], and so the complication rate of right heart catheterization was 6% [3 cases]. None of patients who have undergone right heart catheterization was died.

Cardiomyocyte apoptosis is initiated by various cellular insults and accumulated cardiomyocyte apoptosis leads to the pathogenesis of heart failure. Excessive reactive oxygen species (ROS) provoke apoptotic cascades. Manganese superoxide dismutase (MnSOD) is an important antioxidant enzyme that converts cellular ROS into harmless products. In this study, we demonstrate that MnSOD is down-regulated upon hydrogen peroxide treatment or ischemia/reperfusion (I/R) injury. Enhanced expression of MnSOD attenuates cardiomyocyte apoptosis and myocardial infarction induced by I/R injury. Further, we show that miR-23a directly regulates the expression of MnSOD. miR-23a regulates cardiomyocyte apoptosis by suppressing the expression of MnSOD. Our study reveals a novel model regulating cardiomyocyte apoptosis which is composed of miR-23a and MnSOD. Our study provides a new method to tackling apoptosis related cardiac diseases.

96 patients underwent cardiac valve replacement for valvular heart diseases consecutively between February 1986 to February 1990 in the Department of Thoracic and Cardiovascular Surgery of Yeungnam University Hospital. The follow up period was between 6 months and 4.5 years postoperatively[mean 23.4$\pm$13.1 months]. 75 cases got mitral valve replacement, 6 cases, aortic valve replacement, 15 cases, double valve replacement. 30[31.2%] patients were male and 66[68.8%] were female and the age ranged from 14 to 66 years old. Early hospital death within 30 days postoperation were 5 patients[5.2%], consisting of by low cardiac output in 2, infective endocarditis in 1, multiple organ failure with sepsis in 1 patient. There was no late postoperative death. Most common early postoperative complication was wound disruption [8.7%] and then low cardiac output, pneumothorax, pleural effusion in order. Most common late postoperative complications were minor bleeding episodes[8.7%] related to anticoagulant therapy which were consisted of frequent epistaxis in 3, gum bleeding in 2, hemorrhagic gastritis in 1, hypermenorrhea in 1, hematoma in right arm in 1 patient. Valve-related complications included valve thrombosis [1.6%/ patient-year], valve failure due to pannus formation[1.1% /patient-year], prosthetic valve endocarditis[1, 1%o/patient-year] and minor anticoagulant hemorrhage[4.4% /patient-year]. 5 cases of reoperations were performed in 4 patients due to valve failure and all of them were in the mitral positions[2.7% /patient-year]. Cardiothoracic ratios in the chest X-ray decreased at the 6th month and 1st year postoperation in all patients. But in New York Heart Association[NYHA] functional class IV, no change in cardiothoracic ratio was found between 6 months and 1 year postoperation. In the echocardiogram, the size of the cardiac chambers decreased, but ejection fraction increased postoperatively in each functional class. In the electrocardiogram, decreases were found in the incidence of atrial fibrillation, left atrial enlargement, left ventricular hypertrophy with right bundle branch block increasing postoperatively in each functional class. The actuarial survival rate was 98.4% for all patients, 98.7% for mitral valve replacement, 83.8% for aortic valve replacement, and 80% for double valve replacement at the end of a 4.5 year follow up period. Meanwhile the actuarial freedom rate was 91.5% for prosthetic valve endocarditis, 91.6% for thromboembolism, 89.0% for prosthetic valve failure and 83.7% for minor anticoagulant hemorrhage. Preoperative NYHA class III and IV were 75% of all patients, but 95% of all patients were up graded to NYHA class I and II postoperatively.

Background: Little is known about the long-term effects of angiotensin-converting enzyme (ACE) treatment on post-tuberculosis emphysema. This study evaluated the effects of ACE inhibition on cardiac function and gas exchange in patients with post-tuberculosis emphysema. Methods: At baseline and at 6 months after initiation of ACE inhibition therapy, patients underwent pulmonary function testing, arterial blood gas analysis, and echocardiography, both at rest and post exercise. Cardiac output (CO) and right ventricular ejection fraction (RVEF) were measured at those time points as well. Results: After ACE inhibition; resting and post-exercise RVEF ($Mean{\pm}SEM,\;61.5{\pm}1.0,\;67.6{\pm}1.2%$, respectively) were higher than at baseline ($56.9{\pm}1.2,\;53.5{\pm}1.7%$). Resting and post-exercise CO ($6.37{\pm}0.24,\;8.27{\pm}0.34L/min$) were higher than at baseline ($5.42{\pm}0.22,\;6.72{\pm}0.24L/min$). Resting and post-exercise $PaO_2$ ($83.8{\pm}1.6,\;74.0{\pm}1.2mmHg$, respectively) were also higher than at baseline ($74.2{\pm}1.9,\;66.6{\pm}1.6mmHg$). Post-exercise $PaCO_2$($46.3{\pm}1.1mmHg$) was higher than at baseline ($44.9{\pm}1.1;\; Resting\;42.8{\pm}0.8\;vs.\;42.4{\pm}0.9mmHg$). Resting and post-exercise A-a $O_2$ gradient ($12.4{\pm}1.4,\;17.8{\pm}1.5 mmHg$) were lower than at baseline ($22.5{\pm}1.5,\;26.9{\pm}1.6mmHg$). Conclusion: In post-tuberculosis emphysema, RVEF and CO were augmented with a resultant increase in peripheral oxygen delivery after ACE inhibition. These findings suggest that an ACE inhibitor may have the potential to alleviate co-morbid cardiac conditions and benefit the patients with post-tuberculosis emphysema.

Genetic and environmental factors are the two areas which have received attention in the etiology of congenital cardiac malformation. Genetic factor in many types of congenital heart disease have not been clearly delineated. Congenital heart diseases are a heterogenous category of developmental anomalies, representing in most cases the multifactorial inheritance of threshold characters, the expression of which is the product of a genetic - environmental interaction. Recently we experienced three pairs of congenital heart disease in siblings including ventricular septal defects in twin.

Atherosclerosis is a main cause of cardiovascular diseases (that is angina. hypertension. cardiac infarction) and stroke. High level of low-density lipoproteins (LDL) in blood has been implicated as an important factor of atherosclerosis progression. Recently researches in endothelial cells unveiled the roles of Iysophosphatidylcholine (LPC). a constituent of oxidized LDL in atherosclerosis. (omitted)
