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.

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.

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.

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.

Irritant or allergic contact dermatitis presents usually eczematous process or occasionally noneczematous lesions like in this case. We report a case of erythema rnultiforme-like eruptions in a 40-year-old female who presented multiple iris or annular shaped maculopapular eruptions on both hands and forearms after contact of lacquer tree. Being performed with standard patch test screening series, lacquer tree extracts and urushiol, she showed significant reactions to the lacquer tree and urushiol. Histopathologic findings showed both features of erythema multiforme and suh acute contact dermatitis.

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.

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.
