2.Production and characterization of monoclonal antibodies to perchloric acid soluble antigen of M. tuberculosis(TB-II).
Journal of the Korean Pediatric Society 1993;36(8):1116-1123
Mycobacteria cause diseases which occur the world over and which carry a considerable burden in morbidity, mortality and social problems. A battery of monoclonal antibodies specific for mycobacterial antigens would provide a useful tool for rapid diagnosis of mycobacterial diseases. Fourteen monoclonal antibodies to perchloric acid soluble antigen of M. tuberculosis were produced. Immunoglobulin isotypes of monoclonal antibodies were ten of immunoglobulin G2a, two of IgG3, and two of IgM. By means of Western blotting, monoclonal antibody detected the antigen of 54kD in TB-P. In the immunofluorescence assay, the monoclonal antibody showed a positive reaction with intact M. tuberculosis bacilli, M. tuberculosis in the pulmonary tissue of tuberculous patient and M. bovis BCG.

4.The Assessment of Left Ventricular Intrinsic Contractility in Pure Rheumatic Mitral Stenosis.
Korean Circulation Journal 1991;21(4):737-744
The status of left ventricular (LV) intrinsic contractile function in pure rheumatic mitral stenosis is an unsettled issue. Although the overall LV ejection performance is reduced in a number of patients with MS, it is the product of the interaction of four variables; intrinsic myocardial contractile state, end-diastolic myocardial length(preload), afterload and LV myocardial mass. Although LV intrinsic contractility in MS has been found to be normal in previous studies, we found it to be decreased on the basis of newer techniques for assessing cardiac mechanics. Reliable load-independent indexes of intrinsic contractility using M-mode echocardiography are end-systolic pressure or end-systolic meridian wall stress to end-systolic volume or dimension ratio and fractional fiber shortening to end-systolic stress relations. We assessed LV intrinsic myocardial contractile state as measured by the aforementioned methods in patients with pure rheumatic MS. The results were as follows; 1) The clinical characteristics are no statistical significance of differences between the 2 groups. 2) Preload (LV end-diastolic volume index) was increased in patients with MS(77+/-23 VS 67+/-21 ml/m2, p<0.05). Fractional fiber shortening and LV ejection fraction were significantly lower in patients with MS(31+/-7 VS 40+/-7%, 66+/-9 VS 77+/-8%, p<0.001). 3) End-systolic stress was significantly elevated in the patient population compared with the control subjects (70.1+/-18 VS 50.5+/-10 dynes-cm2x103, p<0.001) The increased in end-systolic stress in the presence of reduced systolic blood pressure(106+/-8 VS 116+/-7mmHg, p<0.001) was due to a higher end-systolic volume index(26+/-12 VS 15+/-6ml/m2 p<0.005) and reduced systolic wall thickening (1.13+/-0.2 VS 1.54+/-0.2cm, p<0.001). 4) The end-systolic stress to volume index ratio and systolic pressure to end-systoli volume ratio were significantly lower in patients with MS(p<0.001). Relation between LV end-systolic wall stress and fractional shortening in patients with MS superimposed on 95% confidence limits of values in 105 normal control subjects derived from a previous study(r=-0.58, p<0.005). Thirty-six(75%) patients were below the 95% confidence limits of normal values.

This study was performed to guide the effective utilization of blood and optimal blood ordering schedule for various elective surgeries, based on the analysis of 1,462 transfused surgical procedures and 5,933 blood units transfused during operation in the period of two years through January, 197 to December, 1988 at Yeungnam University Hospital. The frequency of transfusion, and mean transfused units were evaluated and recommended blood unit for each surgical procedure was proposed. We assure that the successful establishment of this guideline can lead to substantial monetary saving, reduced blood outdating, and a decreased blood bank workload with a more appropriate allocation of the technician's time and effort.

Yeungnam University Journal of Medicine 1990;7(2):159-165
The prevalence of low serum urea nitrogen concentrations (<6 mg/dL) in our patient population was 3.8% (452 per 11,911 determinations), representing 372 individual cases. Of these, 323 of the patients' charts were located, reviewed, and classified into disease groups. Malignant tumor was found in 25.1% of the 323 patients, the remaining patients without malignant tumor had various clinical conditions; pregnancy (19.5%), infectious diseases (12.1%), trauma (10.2%), cerebrovascular accident (6.2%), hepatopathy (5.3%), and miscellaneous conditions (21.6%). The prevalence in female and young aged patients under 5 years was considered due to the lower reference range in these groups than in that of female adult groups, and moreover pregnancy in another superimposing factor in the former group. In regards to the causes of this condition, our study corresponded well to the textbook cited etiology of the low serum nitrogen concentration, although malnutrition and hepatopathy were inverted in their incidental order. We postulated, through the present study, that the low serum urea nitrogen concentration is not pathognomonic findings to suggest specific disease or conditions, but rather to reflect patient's general conditions such as hydration, nutrition, or administration of certain drugs.

Patau syndrome, or Trisomy 13 is one of the most common autosomal aberration associtated with multiple congenital abnormalities. We report a case with trisomy 13 mosacism which was found during an amniocentesis performed due to the age of the mother and abnormal nuchal translucency. The clinical features of fetus included cleft lip and palate, low set ears, polydactily, small ""micro"" penis, and Rocker-bottom feet. After termination of the pregnancy, the fetus was sent for an autopsy. The autopsy report was compatible with the gross findings and pulmonary hypoplasia, microophthalmia, hypoplasia of left ventricle of heart were found.

The present study was designed to evaluate the efficiency of total lactate dehydrogenase, total creatine kinase, LD1/LD2 ratio, CK-MB and newly developed troponin T in acute myocardial infarction. The level of troponin T was 0.010.02 pg/L in 34 healthy person, but the peak vaule of acute myocardial infarction ranged in 4.7-24.2 pg/L. Total lactate dehydrogenase was peaked in 1 to 3 days after chest pain and then progressively decreased, but LD1/LD2 ratio was persistently higher than 1.0 for 10 days in most patients. Total creatine kinase and CK-MB were peaked in 1-2 days, and normalized in 3-4 days, so they, were useful in early diagnosis of acute myocardial infarction, but not for the late stages of acute myocardiz l infarction. Troponin T is early elevated and persistently high level for more than 10 days. Comparing with total lactate dehydrogenase, total creatine kinase, LD1/LD2 ratio and CK-MB, troponin-T test improves the efficiency of serodiagnostic method for the detection of ischemic myocardial damage.

10.Packed Red Cell Transfusion in Neonate: Effects of Age of Red Cells on Serum Laboratory Values and Readjustment of Hematocrit Values after Transfusion.

Sick neonates often require periodic small volume transfusion (10mg/kg) to replace blood draw for laboratory monitoring during their hospital stay. The effect of packed red cel transfudion on the hematocrit, potassium, ionized calcium, acid base status, glucose and indirect bilirubin was investigated in 25 transfusions. Analysis of transfused blood by the age of the red cells, older red cells (more than 5 days old, 13+/-7 days) showed increased potassium (27.2+/-14.1mEq/L vs 11.3+/-4.9mEq/L), decreased bicarbonate (14.4+/-2.6mEq/L) and glucose (130+/-28mg/dl vs 203+/-93mg/dl) compared with newer red cells (less than 5 days)(p<0.05). No significant changes occured in hematocrit and pH. Inspite of these results, the transfusion of the older red cells did not affect the older red cells did not affect the serum potassium, ionized calcium, pH, bicarbonate, glucose and indirect bilirubin level in neonates. The hematocrit of infants increated significantly after transfusion from 29.6%+/-4.3% to 38.3%+/-6.1%(mean+/-SD)(P<0.05). Transfusion of older red cells seemed to be as equally effective as newer ones. The valus of hematocrit obtained immediately after transfusion does not show any differences compared to those obtained 30 min, 1, 2, 4, 6 and 24 hours after transfusion. The result in the study indicate that there was no adverse effect after transfusion with packed red cell more than 5 days old and no significant difference in hematocrit observed between 0 to 24 hours following transfusion. Therfore old red cell more than 5 days can be used safely for sick neonatal transfusion and the stored donor blood can be optimzed for repeated blood transfusion.
