2.Tumor Necrosis Factor-alpha and Interferon-r Secretory Capacity of Mononuclear Leukocytes after Incubation in Patient with Acute Myocardial Infarction.
Korean Circulation Journal 1998;28(4):586-591
BACKGROUND: Studies of human coronary plaque specimens have shown that T lymphocytes and macrophages are present in all types of lesions, from fatty streaks to advanced plaques. There is growing evidence for a pathogenic role for immune response in progression of atherosclerosis. This study was designed to investigate cytokine production by mononuclear leukocytes from patients with myocardial infarction. METHOD: We measured the kinetics of secretion of tumor necrosis factor-alpha (TNF-alpha) and interferon-r (IFN-r) by mononuclear leukocytes from 8 control subjects and 12 patients with acute myocardial infarction. Mononuclear leukocytes were isolated and incubated with plant lectin mitogen concanavalin-A for 24 and 48 hours. TNF-alpha and IFN-r secretions were measured by ELISA. RESULTS:There were no significant differences between TNF-alpha and IFN-r secretions by mononuclear leukocytes at and before 24 hours of incubation from both patients and control subjects, but TNF-alpha and IFN-r secretions at 48 hours of incubation were higher (p<0.005, p<0.05) in patients when compared with control subjects. TNF-alpha and IFN-r secretions by mononuclear leukocytes after incubation correlated with the peak level of creatine phosphokinase (CK) and CK-MB. CONCLUSION: Increased cytokine secretory capacity of mononuclear leukocytes may be due to the acute inflammatory response of myocardial infarction. Further trials may be needed to determined the effects of increase in secretory capacity of mononuclear leukocytes before myocardial infarction.

3.Injury of the Genitourinary Tract, Sung Won Kwon. M.D. and Dong Han Kim. M.D..
Korean Journal of Urology 1968;9(4):181-188
Ninety-one cases of genitourinary tract injuries which were admitted to Severance Hospital during the period from Jan. 1960 to Aug. 1968 were analyzed clinically and statistically. And it was investigated compared with previous papers 1) The rate of genitourinary injuries accounted for 7.3 per cent to the total admission patients during eight years sixty-nine per cent of all injuries were in men and thirty-one per cent in women. The age distribution was much the same as that found in previous literature. Most favorable age was in from 20 to50 years for 72.5 percent 2) The meet common involvement site was in urethra for32.9 per cent while external genitalia showing most common site in war wound Also iatrogenic ureteral injuries was relatively high in spite of most less commonest incidence in previous paper 3) Thirty-six per cent of all injuries weredue to traffic or vehicular accident and twenty-four per cent 'due to iatrogenic. Majority of these iatrogenic injuries occurred in pelvic operation. Falls kick and blow were listed not less frequently. 4) On observation of kidney injuries. predisposed hydronephrotic kidney was injured more frequently due to mild external forces and three cases of sixteen kidney injuries had hydronephrosis dueto stone and congenital ureteral stricture in this series 5) An incidence of ureteral injury during radical hysterectomy was variable in literature. but it was noted around 10 percent generally. In reviewing 197 cases of radical hysterectomy for carcinoma of cervix, incidence of ureteral injuries was 12 cases(7.3 per cent) and it was listed 9.3 percent including bladder injuries. 6) In investigating bladder injuries, 53 percent of injuries were associated with pelvic bone fracture And 87 per cent was extraperitoneal type and 13 per cent wasin intraperitoneal rupture. 7) Also majority of urethral injuries were associatedwith pelvic bone fracture especially in car accident cases and then involved posterior urethra for 85 per cent. And bulbous urethra was injured by straddle injury for 70 per cent.

4.Unusual Three Cases of Adult Coronary Arteriovenous Fistula.
Korean Circulation Journal 1989;19(4):765-769
We report unusual 3 cases of adult coronary arteriovenous fistula(CAVF) diagnosed by coronary arteriography in Soonchunhyang University Hospital. In one patient with mitral stenoinsufficiency, multiple CAVFs originated from left anterior descending and left circumflex coronary areries. In another patient with significant stenosis(90%) in distal right coronary artery, new CAVF was seen in mid right coronary artery during consecutive coronary arteriography. In the remaining one, it was arose from contus branch of right coronary artery. Surgical correction was performed in two cases.

Korean Circulation Journal 1993;23(6):883-891
BACKGROUND: Hemodynamic derangements of cardiac tamponade are generally believed to result from compression of the cardiac chambers, which limits diastolic filling. The character and magnitude of the alternation are determined by the compliance characteristics of the pericardium and the total pericardial fluid volume. During serial pericardial fluid withdrawal, improvement of hemodynamic alternations is expected in patients with pericardial effusion. Method : Hemodynamic study was performed before and during serial fluid drainage in 11 patients with chronic moderate to severe pericardial effusion. RESULTS: 1) Intrapericardial pressure was elevated and equal to mean right atrial ventricular diastolic, and pulmonary capillary wedge pressure. Pulmonary arterial and right ventricular systolic pressure were also midly elevated equal to one another. 2) Pericardial fluid was gradually removed in 50ml aliquots in all patients. The most significant hemodynamic improvement occured during intial 50mL withdrawal. Futher drainage of intrapericardial fluid was accompanied by slight hemodynamic improvement. 3) There were significant correlations between total pericardial fluid volume and intrapericardial and right atrial pressure (r=0.75 (p<0.005), r=0.71(p<0.01)). Correlations between intrapericardial pressure and right atrial, right ventricular diastolic and pulmonary capillary wedge pressure were also significant. 4) Two groups of patient could be distinguished based upon intrapericardial pressure as 7mmHg. More significant hemodynamic changes were in 6 patients with higher intrapericardial pressure after withdrawal of 200mL fluid. CONCLUSION: In chronic moderate to severe pericardial effusion, the most significant hemodynamic improvement occurred during initial fluid drainage. Early pericardiocentesis is important in management of pericardial effusion with high intrapericardial pressure.

Takayasu's arteritis(arteritis syndrome) is an inflammatory disease process affecting primarily the aorta and its main branches. It's etiology and pathogenesis are unknown. Controversy exists in treatment. Segmental stenoses, occlusions, and aneurysmal degeneration of the aorta and the proximal arterial tree are frequent findings. Clinical presentations may include cerebrovascular ischemia, limb ischemia, aortic valvular insufficiency, heart failure, renovascular hypertension, or renal failure. Recently, we experienced a case of Takayasu's arteritis in a 24 years old female with severe dizziness, claudication in right upper extremity. Patient was treated by angioplasty of left vertebral artery and concomitant left subclavian-to-right axillary artery bypass surgery followed by percutaneous transluminal angioplasty with stent therapy of right vertebral artery to prevent cerebrovascular ischemia during the operation. Postoperative result was excellent and dizziness and claudication of right arm were completely relieved.

We observed the motion of left ventricular posterior wall aortic root posterior wall in 20 normal persons and 20 patients with left ventricular hypertrophy during the period from March 1985 to Agust 1985. The results were as followings; 1) The percentage of rapid filling time to one cycle of heart beat obtained from the ventriculat posterior wall motion was significantly prolonged in patients with left ventricular hypertrophy(24.1+/-5.44%) than in normal persons(13.5+/-3.69%)(p<0.05) and that of slow filling time was significantly shortend in patients with left ventricular hypertrophy(27.4+/-6.10%) than in normal persons(38.7+/-9.06%)(P<0.005). 2) The rapid filling slop obtained from left ventricular postrior wall motion was significantly reduced in patients with left ventricular hypertrophy(44.0+/-12.45mm/sec)than in normal persons(91.7+/-53.16mm/sec)(P>0.005) but the slow were not signigficantly different between the two groups. 3) The left artial emptying index calculated from the aortic root posterior wall motion was significantly lower in patients with left ventricular hypertrophy(0.6+/-0.18) than in normal persons(1.1+/-0.26)(P<0.005).
