The author obtained index of red cell volume distribution width(RDW) and other red cell indices in 210 patients of various hematoncologic conditions and 200 healthy control group using, an automated blood analyzer, Coulter Counter Model S-plus II. This study performed to classify various etiologic anemia based on the MCV and RDW, to evaluate availability to the differential diagnosis in korean anemic distoders somewhat different from etiologies of anemias in foreginers. In the most of cases, the increase or decrease of MCV were always combined the pararell changes of MCH and MCHC: But the values of MCV and RDW were not correlated in control group and patient group. So the terms of heterogenous of homogenous anemia were meaningful morphologic classification than hypochromic or normochromic anemia. The heterogenous microcytic anemia contained iron deficiency anemia. In heterogenous normocytic anemia, myelophthisic anemia, acute leukemia were contained. In heterogenous macrocytic anemia, megaloblastic anemia, hemolytic anemia were contained. The homogenous microcytic anemia was observed in anemia of chronic disorders. In homogenous normocytic anemia, acute blood loss, chronic leukemia, multiple myeloma were contained. The aplastic anemia was belonged to homogenous macrocytic anemia. The diagnostic significance of RDW in hemoglobinopathies is most importhant. But this study was not contained hemoglobinopathies. Instead RDW was very helpful to differential diagnosis of most common anemias, iron deficiency anemia and anemia due to chronic disorders in Korea.

BACKGROUND AND OBJECTIVES: Percutaneuous transvenous mitral commissurotomy(PTMC) has been performed as an effective non-surgical treatment modality of rheumatic mitral stenosis. Mitral regurgitation(MR) as a complication of the procedure occur in 20-53% of the patients. The moderate to severe mitral reguargitation, created by the PTMC, sometimes leads to the requirement for mitral valve replacement, but most of the MR limits the optimal dilation of mitral commissure due to the worry about the progression of the MR. This study was designed to evaluate the occurrence of mitral regurgitation and predictive factors for the moderate to severe mitral regurgitation(grade> or =2) induced by PTMC. METHODS: This study enrolled 46 patients(female 42, mean age 45 years) who have performed PTMC in Yeungnam University Hospital from May 1996 to May 1999. We analyzed the occurrence rate of mitral regurgitation(MR) and predictive factors for MR grade> or =2 after procedure. RESULTS: MR was detected in 35% of the patients prior PTMC, and in 56% after the procedure(grade 1, 30%; grade 2, 15%; grade 3, 11%). 21 cases of the MR was commissure MR as a grade< or =2. MR grade 3, occured in 5 patients, was non-commissure MR caused by the unilateral rupture of the lateral commissure in 4 patients and tearing of the annulus in one patient. On the univariate analysis, patients with MR grade> or =2 showed more frequent atrial fibrillation, mitral regurgitation and fluoroscopic calcification, and had more severe symptoms than patients with MR grade<2 before the procedure. On the analysis of the calcification, there was no significant difference of the leaflet calcification score, but the commissure calcification score was significantly higher in MR> or =2 group than MR<2 group(1.5+/-0.54 vs 2.5+/-0.96, p=.02). On the multivariate logistic regression analysis, independent predictor of MR grade> or =2 was fluoroscopic mitral calcification(OR 6.38, p=.048). CONCLUSION: Mild to moderate commissure MR was observed in most of the patients after PTMC. Commissure calcification have more influence on the development of MR grade> or =2 than valvular calcification, and the fluoroscopic mitral calcification can predict the occurrence of MR grade> or =2 mitral regurgitation after PTMC.

The 8 cases of left ventricular thrombus detected by the 2 D echocardiography or left ventriculography, after acute transmural anterior myocardial infarction were effectively lysed by the thrombolytic agents and heparin therapy. The thrombolytic agents were either urokinase or tissue plasminogen activator. Urokinase was infused intravenously at a dose of 1.0 million unit for three days. And tissue plasminogen activator was infused at a dose of 100mg for a day. In all cases, the thrombi were completely lysed. At follow up, no recurrence of left ventricular thrombus was found. We have experienced 2 cases of peripheral embolization in which, left ventricular thrombi were protruding nonmobile type. The one was the embolic cerebral infarction, the other was transient hoarseness and paresthesia on the left foot, which may be transient ischemic attack. These results show that left ventricular thrombi can be treated by intravenous thrombolytic agents without life-threatening complication. However, for the better establishment of the risk and benefit of therapy further investigation is needed.

24-hour ambulatory ECG monitoring has been examined for the evaluation of heart rate and longest pause in 34 patients with chronic atrial fibrillation (20 patients treated with digoxin and 14 patients without treatment). Following results were obtained: 1. In 34 patients, the mean of average heart rates was 75.7±13.8/minute, fastest heart rates 148.0±32.4/minute, slowest heart rates 48.1±8.4/minute, difference between fastest and slowest heart rates in individual patients 99.9±29.0/minute and longest pauses 2.95±1.06seconds. The longest pauses of more than 4.0 seconds occurred in 4 of the 34 patients and made an exception of comparison groups. 2. In 27 of the 34 patients, ventricular premature contractures were developed and in 11 of 27, mainly occurred less than 100/24 hours and aberrant conduction occurred in all patients. 3. In 20 patients treated with digoxin (0.25 mg/day), the mean of average heart rates was 78.4±13.7/minute, fastest heart rates 152.5±33.1/minute, slowest heart rates 48.9±8.5/minute, difference between fastest and slowest heart rates in individual patients 103.6±31.7/minute and longest pauses 2.55±0.50 seconds. 4. In 10 patients without treatment, the mean of average heart rates was 78.0±10.7/minute, fastest heart rates 154.5±26.8/minute, slowest heart rates 50.6±7.1/minute, difference between fastest and slowest heart rates in individual patients 103.9±22.2/minute and longest pauses 2.66±0.39 seconds. 5. The difference of heart rates and longest pauses between patients with treatment and without treatment were statistically not significant (P>0.05). In summary, authors seemed to consider that 24-hour ambulatory ECG was useful and safe method for clinical evaluation of patients with chronic atrial fibrillation.

BACKGROUND: It is well known that ischemic preconditioning protects the heart against infarction or arrhythmias from a subsequent ischemic injury. Two phases of the effect of preconditioning has been explored, early protection and second window of protection at 24 hours. The late protection was seen in some animal model, but the precise mechanism is controversal. This study was designed to evaluate the late cardioprotective effect and role of HSP70 in ischemic preconditioning of cat heart. METHODS: Two groups of cats were studied. Control animals were subjected to an episode of 40-min coronary artery occlusion followed by 30-min reperfusion. Experimental animals were subjected to ischemic preconditioning before the 40-min ishcemia/reperfusion. The preconditioning protocol was comprised of three 5-min episodes of ischemia interspersed by 10-min episodes of reperfusion. After sustained ischemia and reperfusion, left ventricular risk area and infart area were measured by injection of Evans blue bye and triphenyltetrazolium staining, and myocardial HSP70 mRNA was examined in risk(left ventricular anterior wall) and nonrisk(left ventricular posterior wall) area using northern blot hybridization. HSP70 mRNA expression was quantified as a percent of GAPDH. The late cardioprotective effects of ischemic preconditioning were determined by infarct size (% area at risk). RESULTS: Infarct size was markedly limited by ischemic preconditioning when compared with the control group (18.5+/-6.9% vs 38.5+/-11.1%; p<0.001). HSP70 mRNA expression in risk area was much higher in preconditioning group than control group(78+/-12% vs 41+/-11%; p<0.01). But, there was no significant difference of HSP70 mRNA expression in the posterior wall between control and ischemic preconditioning group. CONCLUSIONS: These data suggest that ischemic preconditioning have delayed myocardial protective effect from ischemia. The increase in myocardial HSP70 mRNA may be one of the contributing factors to the delayed cardioprotective effects of ischemic preconditioning in cats.

A clinical review of 31 cases of multiple myeloma which were diagnosed by criteria of the SWOG between May 1983 and February 1990 at Yeungnam University Hospital was done. The results were as followings: 1. The peak incidence was in 7th decade and male to female ratio was 1.8:1. 2. The most common presenting symptom at first diagnosis was bone pain (58%), but fever, dyspnea, dizziness and palpable mass were also noted. 3. The distribution of laboratory findings as following diagnostic criteria of Southwest oncology group (SWOG): Plasmacytoma on tissue biopsy was noted 6 cases, bone marrow plasmacytosis with more than 10% plasma cells was 22 cases, monoclonal globulin spike on serum electrophoresis was 24 cases, lytic bone lesions was observed 22 cases. 4. Initial clinical stages were classified as 2 cases in stage I, 3 cases in stage II, 26 cases in stage III (84%). 5. Immunoelectrophoresis revealed the distribution of IgG 64%, light chain 22%, IgA 10%, Kappa to Lambda ratio of 1.1:1. 6. Hematologic & biochemical findings revealed anemia with <8.5% of hemoglobin in 42%, hypercalcemia with <10.6 mg% of serum calcium in 22%, azotemia >2.0 mg% of serum creatinine in 19%. 7. The multiple punched out lesion of bone x-ray examination were noticed skull (65%), rib (42%), L-spine (35%), pelvis (23%), T-spine (19%).

To assess the role of multiple factors in influencing occurrence of ventricular premature complexes after acute myocardial infarction twenty-four hour Holter electrocardiographic tape recording were made in 40 survivors of an acute myocardial infarction 10 to 20days after attack. Ventricular premature complexes in the early post infarction period were not correlated with left ventricular function, age, sex, smoking, diabetes mellitus, previous angina, and previous myocardial infarction. The occurrence of ventricular premature complexes showed a positive correlation with the occurrence of ST-T change. The occurrence of ventricular premature complexes during sleep hours was compared to the awake state. In 22 patients, the incidence of ventricular premature complexes are excluded from analysis, the 22 of patients, or in 76 percent, sleep was associated with a lowered occurrence of ventricular extrasystoles.

The effect of amiodarone on reperfusion arrhthmias after release of left anterior descending coronary artery(LAD) occlusion was studied in 22 anesthetized cats. All cats underwent 20 minutes LAD occlusion followed by reperfusion and amiodarone(20mg/Kg) or normal saline was given on cats which had reperfusion arrhythmias through the left ventricular catheter to observe the antiarrhythmic effect of amiodarone. And also the incidence and type of arrhymias during occlusion and reperfusion were analyzed. During the 20 minute LAD occlusion, 10 of 22 cats(45%) had no arrhythmias, and 12 cats(55%) had nonsustatined ventricular tachycardia. After release of occlusion, 5 of 22 cats(23%) had no arrthmias, and 17 cats(77%) developed sustained ventricular arrhythmias(ventricular tachycardia (n=5), ventricular fibrillation(n=12)). The 17 cats which had reperfusion arrhythmias were randomly divided and given normal saline(control(n=8)) or amiodarone(amiodarone group(n=9)). There was no difference on 2 groups. The reperfusion arrhythmias disappeared in 6 out of 9 cats(66.7%) vs none of 8 controls(P<0.01). We conclude that amiodarone seems to be the effective antiarrhythmic drug on reperfusion arrhythmias after release of LAD occlusion in anesthetized cats, and might be useful for the treatment of reperfusion arrhythmias in human.
