Fractures of the phalanges of the hand are very common. Many are minor and likely to have a good result. However many other phalangeal fractures cause significant and prolonged disability. Non-union of the tubular bones of the hand are uncommon occurrence, but are often associated with functional deficits. The authors have reviewed 7 cases of non-union of the phalanges which were treated in the department of orthopaedic surgery, National Medical Center from 1978 to 1985. The results were summarized as follows: 1. The non-union of phalangeal bone was defined by clinical symptoms and signs and roentgenological examination. 2. The incidence of non-union of phalangeal bone fractures was 0.9% (7/771 cases.) 3. of 7 patients, there were 6 in male and 1 in female. 4. Non-union occurred more commonly in the second decade and the group between 10 and 30 years of age. 5. Seven cases, all were the right handed, but injury was developed in the left hands except two cases. 6. The causes of non-union were thought as open wound (7 cases), type of fracture (simple or comminution:3 cases), inadequate immobilization (4 cases) and overtraction (1 case). 7. of 7 cases, 4 cases were treated with bone peg graft and K-wire fixation and 2 cases with excision of distal fragment. 8. The clinical union was 9 weeks in average.

To evaluate the effect of Perindopril in patients with essential hypertension, we administered Perindopril 4 to 8mg/day once daily to 30 patients(18 males, 12 females) for 12 weeks. Baseline blood pressure after 4 weeks with placebo was 150.4+/-7.5/102.0+/-4.3mmHg. The blood pressures of the patients were declined significantly at 4th(140.6+/-14.9/95.4+/-6.5), 8th(136.7+/-11.4/91.7+/-7.6), and 12th(132.3+/-11.1/87.5+/-6.9) week(p<0.01) without change of heart rate. The blood pressure of the patients was normalized below 140/30mmHg in 24 patients(80%) and declined diastolic blood pressure more than 10mmHg in one patients. Therefore the response rate of perindopril was 83.3%. There were reported 3 patients who revealed mild adverse reactions as follows; cough, indigestion, dizziness in one each. In conclusion, these results indicate that antihypertensive therapy with perindopril single daily dose was effective in patients with mild to moderate essential hypertension and well tolerated.

BACKGROUND: Hyperlipidemia is the one of the major risk factors causing the atherosclerosis of coronary arteries. Treatment of hyperlipidemia with drugs has been confirmed the effects of therapy showing a decreased incidence of coronary artery disease. Pravastatin is one of the new HMG-CoA reductase inhibitors and we studied the short-term hypolipidemic effects and safety of pravastatin in patients with hyperlipidemia. METHODS: We studied 31 patients(7 males and 24 females ; range of age, 36-67 years) for 12 weeks whose plasma levels of total cholesterol were higher than 250mg% after one month period of diet therapy. Pravastatin was administered 10mg/day and measured lipid profiles at 4 week interval. RESULTS: Pravastatin reduced the plasma total cholesterol from 286.2mg% to 212.3mg% (25.9%), the LDL-cholesterol from 204.2mg% to 143.6mg% (29.7%), the triglyceride from 226.0mg% to 161.4mg% (28.6%) after 12 weeks treatment. The HDL-cholesterol increased from 25.8mg% to 46.4mg% (20.5%) after pravastatin therapy. These changes were disclosed all statistically significant compared to baseline levels(p<0.01). The clinical and laboratory examinations before and after pravastatin treatment showed no particular abnormal findings. CONCLUSIONS: These results suggested that short-term pravastatin therapy in patients with hyperlipidemia seems to be very effective and safe.

To study left ventricular diastolic filling in patient with hypertension in different form of left ventricular hypertrophy(LVH), 105 patients with hypertension and 30 normal persons underwent M-mode echocardiography and pulsed Doppler measurement of the left ventricular inflow. From the M-mode echocardiographic measurement of left ventricular dimension, hypertensive patients were subdivided into three grouops : group I(n=27) ; no LVH, group II(n=36) ; concentric LVH, grooup III(n=42) asymmetric septal hypertrophy. From the digitized trace of the pulsed Doppler at the mitral valve level, Doppler diastolic time intervals, peak velocities at rapid filling (E velocity) and atrial contraction(A velocity) and the triangle area under the A velocity(A area) and triagle area under the E velocity(E area) were measured. The peak A velocity(normal subjects ; 0.51+/-0.08m/sec, group I ; 0.73+/-0.14m/sec, group II ; 0.78+/-0.15m/sec, group III ; 0.8+/-0.23 m/sec) and the A area(noral subjects ; 4.71+/-1.64, group I; 6.24+/-1.78, group II ; 7.75+/-2.93, group III ; 8.05+/-3.11) and the peak A/E velocity ratio and the A/E area ratio were significantly different from the normal controls(P<0.01). The peak E velocity(normal subjects ; 0.76+/-0.13, group I ; 0.7+/-0.12, group II ; 0.63+/-0.12, group III ; 0.59+/-0.15m/sec) and E area (normal subjects ; 9.61+/-2.8, group I ; 8.11+/-2.13, group II ; 7.82+/-2.73, group III ; 7.34+/-3.07) were significantly different between hypertensive groups with LVH and normal controls. Doppler time intervals, total area were not different between groups. This study shows that abnormal pattern of left ventricular diastolic filling occur in patients with hypertension and the peak A velocity and the peak A/E velocity ratio and the peak A/E area ratio are the earliest findings that can detectable by Doppler echocardiography.

Regional left ventricular wall motion was evaluated by two-dimensional echocardiographic technique with floating-axis (internal frame of reference) system in three groups of subject; normal subject (n=12), patients with acute anterior myocardial infraction(n=16), and patients with acute inferior myocardial infraction(n=10). Significant hypokinetic wall motion were detected in apical portion (Mean Percent Shortening; 0.27-5.84% in anterior infraction group and 9.64-13.17% in controls) and apicoanterior portion (MPS; 2.86% in anterior infraction group and 14.13% in controls) in patients with acute anterior myocardial infraction (P<0.01), and inferior portion (MPS; 3.56-6.93% in inferior infraction group and 18.26-19.8% in controls) and apical portion (MPS; 4.04% in inferior infraction group and 9.64% in controls) in patients with acute inferior myocardial infraction (P<0.01) in apical long-axis views. We conclude that echocardiographic wall motion analysis by floating axis system is an accurate non-invasive method for detecting abnormal wall motion in patients with acute anterior and in ferior myocardial infraction.

Direction of blood flow and peak velocity measurement were made in the four cardiac valve and ascending aorta from 87 normal Korean adults (42 men and 45 women, age range 20-63 years) with CW Doppler echocardiography. Measurments of the peak velocities of mitral valve, tricuspid valve and aortic valve (ascending aorta) completed in the apical window using 2.0MHz Pedof transducer. The measurement of pulmonary flow completed in the parasternal view. Also aortic velocity data obtained from suprasternum (70/87), subcostal area (48/87) and right sternal border(41/87). Aortic flow velocity was highest (121+/-11.7 cm/xec), mitral flow velocity was 86.4+/-12.2 cm/sec, pulmonic flow was 85+/-13.3cm/sec, where as tricuspid was lowest (64.8+/-11.2cm/sec). The velocities of aorta obtained from apex (106.9+/-15cm/sec) and suprasternum (113.1+/-18.9cm/sec) were greater than other sites. These normal Doppler data provide a useful information for evaluating flow velocity pattern in patient with various heart disease.

To study factors related to release of atrial natriuretic polypeptide(ANP) in human subjects, instracardiac pressure and plasma ANP concentration in peripheral and central circulation were measured in patients with various heart disease (18 valvular heart disease, 4 congenital heart disease, 2 cardiomyopathy). 1) The concentration in peripheral venous plasma were increased in 14 patients with New York Heart Associaion (NYHA) functional class III-IV (87+/-38 pg/ml) as compared with that in 10 patients with NYHA functional class I-II (39+/-21 pg/ml, P<0.005)and 15 normal subjects (51+/-21 pg/ml, P<0.01). 2)The concentration of plasma ANP in inferior vena cava, right ventricle, pulonary artery, left ventricle and aorta were markedly increased in patient with NYHA functional class III-IV, elevated mean right atrial pressure (MRAP> or =8 mmHg) elevated mean pulmonary capllary wedge pressure (MPCWP> or =15 mmHg) and/or elevated pulminary artery systolic pressure (PASP> or =35 mmHg), as compared with those in patients with NYHA functional class I-II and/or lower intracardiac pressure (MRAP<8 mmHg, MPCWP<15 mmHg, and/or PASP<35 mmHg). 3) A step up in ANP concentration between inferior vena cava and right atrium was seen in patients with elevated MRAP (81+/-28pg/ml, 137+/-60pg/ml, P<0.05), MPCWP (74+/-37pg/ml,112+/-62pg/ml, P<0.05) and/or PASP (75+/-29 pg/ml,119+/-64 pg/ml, P<0.05). But there were no differences among intracardiac ANP concentrations from right atrium though aorta. 4) Plasma concentrations in right atrium, pulmonary artery, left ventricle and aorta correlated with MRAP (r=0.82, 0.63, 0.56, p<0.005 and r=0.52, P<0.01, respectively), MPCWP (r=0.86, 0.75, 0.73 and 0.72 respectively, P<0.005 in all) and PASP (r=0.73, 0.57, 0.68 and 0.59 respectively P<0.005 in all). 5) Left atrial diameter correlated with plasma ANP concentration in peripheral plasma (r=0.55, P<0.01), inferior vena cava (r=0.51, P<0.025), right atrium (r=0.45, P<0.05), right ventricle (r=0.55, P<0.01), pulmonary artery (r=0.52, P<0.01), left ventricle (r=0.55, P<0.01) and aorta (r=0.56, P<0.005). These results suggest that the heart secrets atrial natriuretic polypeptide into right atrium in response to increased mean right atrial pressure, mean pulmonary capillary wedge pressure, pulmonary artery systolic pressure and/or left atrial distention.

To evaluate the efficacy and safety of lovastatin, new hypolipidemic agent of HMG-CoA reductase inhibitor, we administered lovastatin 40mg to 80mg once daily for 12 weeks in 20 patients(7 males, 13 females) with primary hypercholesterolemia, and observed the sequential chamges of the lipid profile every 4 weeks. The results are as follows ; 1) The seurm total cholesterol was reduced significantly by 31% from 321+/-36mg% to 210+/-26mg%(p<0.05). 2) The serum triglycerides was significantly reduced from 321+/-168mg% to 228+/-74mg% by 29%(p<0.05). 3) The low density lipoprotein cholesterol was reduced significantly from 177+/-36mg% to 120+/-22mg% by 32%(p<0.05). 4) The total lipid, high density lipoprotein cholesterol and very low density lipoprotein cholesterol were also reduced significantly. 5) The ratio between total cholesterol and high density lipoprotein cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol did not change after lovastatin therapy. 6) There was no adverse reaction due to lovastatin therapy during 12 weeks of therapy. These results suggested that lovastatin is a effective and safe now hypolipidemic agent and is a convenient HMG-CoA reductase inhibitor for clinical use.
