AbstractAbstract PDF
Background
:Unexpected antibodies can cause hemolytic transfusion reaction or decrease the survival of transfused red blood cells. Type and screen is recommended for efficient transfusion, so we perform antibody screening test for pre-transfusion test. In this study, we investigated the frequency and distribution of unexpected antibodies at Yeungnam University Hospital during recent 5 years.
Methods
:We analyzed the results of 28,944 antibody screening test that were performed for preparation of packed red cells from 2002 to 2006. Screening and identification of unexpected antibodies were carried out using a column agglutination method with the DiaMed ID system.
Results
:Unexpected antibodies were detected from 234 samples (0.84%) out of 28,944 samples. After exclusion of samples from same patients, 185 patients had unexpected antibodies. Identification of unexpected antibodies were performed from 108 patients. Antibody that was detected most frequently was anti-E (36.1%), followed by anti-C and anti-Lea (6.5%), anti-c (4.6%), anti-D (3.7%), anti-Jkb (3.0%), anti-Jka, anti-S, anti-Xga (1.9%), anti-e, anti-Fya, anti-M, anti-Jsa and anti-Lub (0.9%). 15 patients (13.9%) had autoantibodies and 20 cases (18.5%) could not be identified by LISS/Coombs method.
Conclusion
:The frequency of unexpected antibodies at our hospital was 0.84%, and the most identified unexpected antibodies were clinically significant. Therefore, antibody screening and identification tests are critical step in pre-transfusion test.

AbstractAbstract PDF
46,XY pure gonadal dysgenesis is a sex-reversal disorder, that is characterized by the presence of a female phenotype, with a normal to tall stature, primary amenorrhea and sexual infantilism. The internal genitalia are female with a uterus and vagina being present, however, there are bilateral dysgenetic gonads. In addition, neoplasia occurs in 20∼30% of patients who have gonadal dysgenesis and a Y chromosome. A 34 year old woman presented to our hospital with the chief complaint of primary amenorrhea. Physical examination revealed no secondary sexual characteristics and no somatic abnormality. Peripheral blood karyotype was 46,XY, and polymerase chain reaction (PCR) for the Sex determining Region Y (SRY) gene was positive. Sequencing analysis of the SRY gene revealed a single nucleotide polymorphism. A laparoscopic gonadectomy was performed to remove both gonads, and no tumor cells were observed. Estrogen replacement therapy was instituted.

AbstractAbstract PDF
According to the World Health Organization (WHO) classification system, cases with t(8;21)(q22;q22) should be diagnosed as acute myeloid leukemia (AML) even with a blast count of less than 20 percent in blood or bone marrow. It is an uncommon manifestation, moreover hypocellularity is rarely observed in this subtype of leukemia. Here, we report a case of t(8;21) in a patient with marked hypocellularity of less than 5 percent and a blast count of less than 20 percent. This patient responded relatively well to chemotherapy. An allogeneic bone marrow transplantation was performed with good engraftment . This case suggests that hypocellular AML with a t(8;21) has as good a prognosis as hypercellular AML with t(8;21).

AbstractAbstract PDF
Simultaneous deficiency of Vitamin B12 and iron induces that the bone marrow erythroid megaloblastosis and peripheral blood macroovalocytosis are masked because of countervailing the tendency of iron deficiency to produce hypochromic microcytic erythrocytes. We report two cases of Vitamin B12 deficiency anemia with low mean corpuscular volume (MCV) due to combined iron deficiency anemia with review of literature.

AbstractAbstract PDF
The enzyme activities of creatine kinase(CK), its isoenzyme MB(CK-MB) and of lactate dehydrogenase isoenzyme 1(LD-1) have been used for years in diagnosing patients with chest pain in order to differentiate patients with acute myocardial infarction(AMI) from non-AMI patients. These methods are easy to perform as automated analyses, but they are not specific for cardiac muscle damage. During the early 90's the situation changed. First, creatine kinase MB mass(CK-MB mass) replaced the measurement of CK-MB activity. Subsequently cardiac-specific proteins, troponin T(cTnT) and troponin I(cTnI) appeared and displacing LS-1 analysis. However troponin concentration in blood increase only from four to six hours after onset of chest pain. Therefore a rapid marker such as myoglobin, fatty acid binding protein or glycogen phosphorylase BB could be used in early diagnosis of AMI. On the other hand, CK-MB isoforms alone may also be useful in rapid diagnosis of cardiac muscle damage. Myoglobin, CK-MB mass, cTnT and cTnI are nowadays wisely used in diagnosing patients with acute chest pain. Myoglobin is not cardiac-specific and therefore requires supplementation with some other analysis such as troponins to support the myoglobin value. Troponins are very highly cardiac-specific. Only the sera of some patients with severe renal failure, which requires hemodialysis, have elevated cTnT and/or cTnI without there being any evidence of cardiac damage. The latest studies have shown that elevated troponin levels in sera of hemodialysis patients point to an increased risk of future cardiac events in a similar manner to the elevated troponin values in sera of patiets with unstable angina pectoris. In addition, the bedside tests for cTnT and cTnI alone or together with myoglobin and CK-MB mass can be used instead of quantitative analyses in the diagnosis of patients with chest pain. These rapid tests are easy to perform and they do not require expensive instrumentation. For the diagnosis patients with chest pain, routinely myoglobin and CK-MB mass measurements should be performed whenever they are requested (24 h/day) and cTnT and cTnI on admission to the hospital and then 4-6 and 12 hours later and maintained less than 10% imprecision.

AbstractAbstract PDF
BACKGROUND
Extended-spectrum beta-lactamases(ESBL) are enzymes that confer resistance to oxyimino-beta-lactams as well as to penicillins and cephalosporins. Strains of Klebsiella pneumoniae and Escherichia coli that produce ESBL have been increasingly prevalent in many countries. The purpose of this study was to investigate the ESBL production rate of K. pneumoniae and E. coli at the in Yeungnam University Medical Center. MATERIALS AND METHODS: Thirty-one isolates of K. pneumoniae and twenty-five isolates of E. coli were examined for ESBL by double disk synergy test, using 20/10microgram ticarcillin/clavulanic acid and 30microgram oxymino-beta-lactam(ceftazidime, ceftriaxone and aztreonam) disks. RESULTS: Fifty-two percent of K. pneumoniae and sixteen percent of E. coli isolates revealed double disk synersism. Majority of ESBL-producing strains(fifty-five percent) were isolated from patients in the intensive care unit. CONCLUSION: ESBL production of K. pneumoniae and E. coli were also common at the Yeungnam Univercity Medical Center and pose a serious problem for antimicrobial therapy.

AbstractAbstract PDF
The aim of this study was to evaluate domestic enzyme immunoassay(EIA) kit ?LG HCD 3.0?(LG) for the detection of antibody to hepatitis C virus(anti-HCV) in comparision with Axsym HCV version 3.0(Axsym), Cobas Core anti-HCV EIA(Cobas). Cobas kit shows better clear distinction between positive and negative by signal/cutoff ratio(S/C), but it also reveal relatively high false positive rate. The concordance rate of test results between LG and Axsym was 96.2%, between LG and Cobas was 95.5%, and total agreement between three EIA kit was 93.9%. LG were relative poor distinction between positive and negative results, but it could be applied clinically as a screening tool for hepatitis C in general population. The S/C of one false negative result by LG was 0.91, and false positive were less than 4.0, therefore we concluded it is necessary to confirm by immunoblotting assay when S/C were between 0.8 and 4.0.

AbstractAbstract PDF
We studied the expression of the cell surface antigen associated with myeloid and lymphoid leukemias on bone marrow or peripheral blood blast cells from 153 leukemic patients including 61 cases of acute myelogenous leukemias(AML), 46 of acute lymphocytic leukemias(ALL) and 12 of acute leukemias. They were analyzed by direct or indirect immunofluorescence method for reactivity with the monoclonal antibodies to B cells(CD10, CD19, SmIg), T cells(CD2, CD5, CD7, CD3, CD4, CD8), myeloid antigen(CD13, CD14, CD33, CD61) and a nonspecific antigen, HLA-DR. Lymphoid associated markers detected on AML is CD7 32.8%, CD10 14.8%, CD5 13.1%, CD2 6.6% and CD19 1.6%. TdT was positive in 4.9% of AMLs. Hybrid leukemias were 8 cases out 61 AML cases and were mainly composed of monocytic lineage, M4 and M5a. Myeloid markers detected in ALL were CD13 2.2% and CD33 2.2%. In this study, immunologically classified ALLs were composed of 65.2% of CALLA (+) B precursor type, 10.9% of CALLA (-) B precursor pattern, 8.7% of T cell type, 2.2% of B cell type, 4.5% of mixed lymphoid lineage(B&T), 2.2% of undifferentiated leukemia, and 6.5% of hybrid leukemia. Twelve cases of acute leukemias ware finally diagnosed to be 5 cases of hybrid leukemia, 3 cases of B lineage, 3 case of T lineage and 1 case of mixed lymphoid(B&T) leukemia. In summary, we think the best method for typing acute leukemias is by using a combination of FAB classification and immunophenotying.

AbstractAbstract PDF
Four subtypes of hepatitis B surface antigen are useful in the epidemiologic studies of the route of virus transmission and clinical significance of simultaneous occurance of hepatitis B surface antigen and antibody to hepatitis B surface antigen in the same serum as well as useful marker for population migration. The sera were obtained from 214 HBs Ag positive patients who are diagnosed as chronic liver disease and following up in the Yeungnam university hospital. The subtypes were determined by solid-phase sandwich EM using monoclonal antibodies. Among 214 specimens, the subtype adr was 93.9%, adw was 2.8%, ayr was 0.9%, ar was 0.9%, adwr was 1.4% and ayw was not detected. There were no correlation between subtype pattern and disease. In summary, the subtype adr was prominent in our study and the difference of subtype pattern by severity of disease was not significant. However, to determine the prognostic value of HBs Ag subtype and relationship between subtype and disease progression, long-term follow up will be needed.

AbstractAbstract PDF
The ESR is one of the oldest laboratory test still in use. Although it lacks specificity in diagnosis, it can be effective for monitoring disease activity and following-up. The Westergren method is used for reference method, however coefficient of variation has been described 0.8% to 22.9% according to the literature. Since the ESR was invented in 1921, measurement technique has developed and automated measurement is introduced. We analyzed one hundred forty-three patient samples using SEDIsystem' automated ESR measuring system and compared with modified Westergren and Wintrobe methods. Comparison between SEDIsystem' and modified Westergren for ESR measurement yields the following regression equation; y = 0.863x - 1.69 (r=0.830), SEDIsystem'M and Wintrobe y'= 1.14x - 14.7 (r=0.789), rcspectively. We repeated measurement to evaluate reliability, results are not significant in statistically. In conclusion, SEDIsysten' automated ESR measurement correlated with modified Westergren and Wintro" ; methods, reveal reliable results after 4 hours and can report rapidly for large samples. Thus, these results indicate that SEDIsystenT"' automated ESR measurement may be useful tool for clinical practice.

AbstractAbstract PDF
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.

AbstractAbstract PDF
In the method for lithium (Li) analysis, flame emission photometry and atomic absorption spectrophotometry (AAS) have been used most frequently. In addition, lithium can be analyzed by ion-selective electrode (ISE) or fluorscence polarization immunoassay. We evaluated the comparison between AAS method based on the principle of absorption of light at 670.8 nm by Li and ISE method based on the principle of voliage difference generated by Li in contact with lithium ionophore. We compared with those obtained by AAS (AA/AE Spectrophotometer 551, Instrumentation Laboratory Co.) and ISE (SYNCHRON EL-ISE, Beckman Co.) in the serum and urine of 6 pati,,:nts- and evaluated time-related changes of serum lithium concentration after dosing in both methods. The results are summarized-as follows: 1. In within-run precision study for lithium concentration, coefficient variations (CVs, %) ranged from 1.34 to 2.17 for AAS and from 0.34 to 0.85 for ISE method. In between-run precision study for lithium concentration, CVs ranged from 1.23 to 1.72 for AAS and from 0.61 to 1.38 for ISE method. 2. The correlation study between AAS and ISE method resulted in Y= 0.946X+ 0.137 (N = 32, r= 0. 933, X= AAS, Y= ISE) for serum lithium and Y= 1. 092X+ 0. 977 (N= 28, r= 0.943, X= AAS, Y= ISE) for urine lithium. 3. Time-related changes of serum lithium concentration in both AAS and ISE method resulted in peak serum levels about 2 hours after dosing and then rapidly decreased after the peak serum level and finally arrived at nearly initial levels about 9 hours after dosing. 4. The reference range of serum lithium was found as undetectable level for both AAS and ISE method and the reference range of urine lithium to the urine creatinine was 0 0.00014 mmol/mg(mean 0.00002 mmol/mg) for AAS method.

AbstractAbstract PDF
Major pathogenic Gramnegative organisms such as P. aeruginosa, Serratia species, E. coli, Enterobacter species which are isolated from the specimens in large medical centers are greatly resistant to the commonly used antibiotics. Gramnegative bacilli, which had been isolated in Yeungnam Uni rersity Hospital during the period from December 1992 to April 1993 and turned out to be resistant to the primary antibiotics susceptibility test for chloramphenicoi, ampicillin, eephaiothin,- geniamicitt, tetracyclin, amikin and tobramycin, were subjected to the secondary antibiotics susceptibility test for aztreonam, ceftazidime, ciprofloxacine, cefotaxime, cefamandole, piperacillin, ticarcillin and sulfamethoxazole trimethopime. Out of 315 tested organisms, 167 organisms (53%) were resistant to all secondary antibiotics in vitro. Antimicrobial activity of ceftazidime (37.1%), aztreonam (11. %), ciprofloxacine (7.9%) against Gram negative bacilli were slightly more active than other antibiotics tested, while cefamandole was not active to all the Gramnegative bacilli tested. According to the specimens, E. coli was the most frequently resistant organisms to the primary antibiotics from urine, A. baumanii, from respiratory system and wounds, and P. aeruginosa from various specimens. In summary, Gram negative bacilli resistant to the primarily applied antibiotics also were resistant to the secondary antibiotics. Rearrangement of the antibiotics disks for the antibiotic susceptibility test should be considered.

AbstractAbstract PDF
Two types of urine dipstick assays, Multistix-SG and Comber-9-Test RL, were compared for compatibility, accuracy, specificity and predictive values of a positive and negative test in 501 patients' urine and artificially prepared specimen. We found that the results of semiquantitative tests of Multistix-SG and Comber-9-Test RL performed were statistically similar in patients' specimen. The urinary leukocyte esterase tests of Comber-9-Test RL assays compared with urine sediment microscopy in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test 83.7%, 48.1%, 90.3%, 47.4% and 90.1%, respectively. The urinary nitrite tests of Comber-9-Test RL assays compared with urine culture tests, in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test were 90.3%, 19.4%, 84.7%, 53.8% and 94.1, respectively. For the urinary protein, the sulfosalicylic acid method was the most sensitive test for any kinds of protein, and Multistix-SG appeared more sensitive than Comber-9-Test RL for the albuminuria. For the urinary bilirubin and glucose, two dipstick assays were similar in their diagnostic efficiency. Finally in the urinary occult blood tests, Comber-9-Test RL assays was more sensitive than Multistix-SG.

AbstractAbstract PDF
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.

AbstractAbstract PDF
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.

AbstractAbstract PDF
Paroxysmal Nocturnal Hemoglobinuria (PNH) is an uncommon hematologic disease characterized by an abnormal sensitivity of blood cells to the lytic action of serum complement. We experienced one case of PNH in Yeungnam University Hospital from May 1983 to May 1989. The patients was followed up without severe complications of 4 years since diagnosis with the only conservative treatments such as washed blood transfusion, adrenal corticosteroids, androgens, folate and iron preparation, intermittently.

AbstractAbstract PDF
We measured fasting Serum Angiotensin-Converting Enzyme (SACE) in 100 healthy controls and 75 coal worker's pneumoconiosis (CWP) patients by a commercial kits (ACEcolor®, Fujirio Inc., Japan) and evaluated this manual method. The linear range extends to an activity of 80U/L. Precision on a commercial control serum (ACE control-N®, Sigma Co.) with a mean value of 9.47U/L yielded a within-run and between-run CVs are 5.6% (N=15) and 6.9% (N=14) respectively. Save in 75 CWP was 20.3±5.7U/L (mean±s.d.); higher than in healthy controls (13.4±3.9U/L, P<0.01). No correlation was found between SACE, sex, and age. The results suggest that the measurement for SACE and follow-up SACE in coal workers may be a useful diagnostic tools for CWP.

AbstractAbstract PDF
Serum lactate dehydrogenase isoenzyme are separated 5 fractions (LD1-LD5) in normal serum by agarose electrophoresis. An unusual band on the cathodic side of LD5 isoenzyme has been found on lactate dehydrogenase electrophoresis is of serum, called LD6, and the presence of which signifies a poor prognosis for the patients of myocardial infarction. In recent, we have experienced LD6 in two patients with myocardial infarction. Cardiac arrest was noted within 24 hours after exhibition of LD6 extra band and they did not recover from their illness.

AbstractAbstract PDF
Pure red cell aplasia in uncommon disorder characterized by finding of anemia, absence of nucleated red blood cell in the marrow, absence of reticulocytes in the peripheral blood and normal peripheral platelet and leukocytes counts. We experienced one case of pure red cell aplasia associated with hemolytic anemia characterized by hemoglobinuria, reticulocytopenia, and erythroid hypoplasia of the bone marrow. The cause of the illness was not definitely identified, but we concluded that this patient had simultaneous occurrence of PRCA and hemolytic anemia following administration of diphenylhydantoin after craniotomy rather than virus or bacteria induced. The simultaneous occurrence of PRCA and hemolytic anemia in uncommon and the mechanism for diphenylhydantoin induced PRCA and hemolytic anemia is unclear.

AbstractAbstract PDF
Reviewing the results of the blood cultures performed at Yeungnam University Hospital during 4-year-period through January, 1, 1984 to December 31, 1987, the following results were obtained. 1) Out of 8083 blood specimens cultured microorganisms grew in 582 specimens with positivity rate of 7.20%. Polymicrobial bacteremia was found in 16 patients. 2) Among 582 positive specimens, Gram-positive cocci grew in 189 specimens, and Gram-negative bacilli, in 393 specimens. Clinically significant microorganisms consisted of 82 Staphylococcus aureus, and 20 Streptococcus species in Gram-positive cocci group, 80 Salmonella typhi, 72 Escherichia coli, 72 Salmonella paratyphi A in Enterobacteriaceae, and 46 Pseudomonas cepacia, and 16 Pseudomonas aeruginosa in glucose non-fermenting microorganisms. 3) Increasing incidence of Serratia, Acinetobacter and Pseudomonas species as major nosocomial infection source is noteworthy. They showed increased tendency from 6.3% of 1984 to 17.7% of 1987 of total positive blood cultures. 4) High isolation rate of Pseudomonas species and Aeromonas hydrophila was noted in summer, while Salmonella typhi showed high prevalence from May to September and in January. 5) In susceptibility tests of isolated organisms, staphylococcus aureus was sensitive to basic antimicrobial agents except for ampicillin. The glucose non-fermenting microorganisms showed high resistance to basic antimicrobial agents in 32.2%. In conclusion, considering the relatively higher incidence of growth of Staphylococcus epidermidis than ideal level indicates that sampling technique should be improved. Secondly, all the hospital staffs in cooperation with Hospital Infection Committee are desirable to pay efforts to decrease the nosocomial infection.

AbstractAbstract PDF
The term histiocytic medullary reticulosis first was introduced by Scott and Robb-Smith. It is a clinicopathologic syndrome characterized by wasting, fever, lymphadenopathy, hepatosplenomegaly, pancytopenia, and is often accompanied by jaundice, purpura. Cardinal pathologic feature are systemized proliferation of atypical, neoplastic, erythrophagocytic D. We are here reporting one case which considered compatible for HMR, with a few elementary reviewed literatures.

AbstractAbstract PDF
Experiments were conducted to define the optimal constituents of culture medium and atmospheric condition for growth of Campylobacter pylori. Two clinical isolates were streaked onto various media, incubated in two different atmospheric conditions (microaerophilic condition and carbon dioxide incubator), and growth was assessed semiquantitatively according to relative colony size and extent of growth through the streak. The growth obtained on Campy media, composed of GC agar base plus 1% hemoglobin, 0.2% activated charcoal, 1% IsoVitaleX, vancomycin 6mg /L nalidixic acid 20mg/L and amphotercin 2 mg/L, was used as reference. Our conclusions were as follows: Tryptic soy agar base was not acceptable for the growth of C. pylori. The organism grew in both atmospheric conditions, but generally showed a scantier growth in the carbon dioxide incubator than under the microaerophilic condition, however GC agar containing 1% hemoglobin and 0.2% activated charcoal supported well the growth of C. pylori in the carbon dioxide incubator. The authors have found that the GC agar base supplemented with 1% hemoglobin and 0.2% charcoal was the most satisfactory medium and a microaerophilic condition was optimal atmospheric condition for the growth of Campylobacter pylori in this study.
