We evaluated a multichannel dry chemical analyzer "Ektachem 750 XRC" for emergency tests according to NCCLS guidelines. Results were fo lowed as below. 1. The evaluation of between-run precision and within-run precision about Na^+, K^+, C1^-, glucose, Cr, ALT, ammonia and amylase revealed high coefficients of variation. 2. In the evaluation of linearity, K^+, glucose, ALT and Cr showed high linearity as r=0.99, r=0.99, r=0.99 and r=0.94 respectively. 3. The correlation studies about Na^+, K^+, Cl^- were performer with NOVA 13. Correlation coefficients of Na^+, K^+ and Cl^- were r=0.93, r=0.99 and r=0.96 respectively. The correlation coefficients of ALT, glucose and Cr with HITACHI 736-20 were r= 0.99, r=0.99 and r=0.94 respectively. We concluded that Kodak Ektachem 750 XRC was suitable as emergency chemistry autoanalyzer because of high precision, linearity and relatively high correlation coefficients.

Objective: This study was designed to evaluate diagnosis and complication, prognosis during clinical study of cases of intrauterine fetal death. Methods and materials: This is a clinical study of 56 cases of the intrauterine fetal death among 8064 deliveries at Seoul Sunchunhyang university hospital during 5 years from January, 1994 to December, 1998. Results: The incidence was 0.7%. The age distribution of mothers was 18 - 44 years and was highest in the 25 - 29 years range(46.4%). The parity was the most highest in the nulliparous group(51.8%). The most common gestational weeks was 20 - 28 weeks gestational period(46.4%), and most common presentation was cephalic(73.5%). The most common weights of the intrauterine fetal death was from 5,00gm to 1,000g(48.2%). The mode of the most common delivery was the induction of delivery(57.2%). The etiologic factors were: unknown(42.9%), preeclampsia(17.9%), chorioamnionitis(14.3%), congenital anomaly(12.5%), abruptio placenta(7.1%), cord complication(3.6%), placenta previa, death of one for twin. There were 2 cases of maternal complication(DIC, Uterine atony). Conclusion : Intrauterine fetal death should be diagnosised early and treated properly to reduce risk of the maternal complication.

Study Design : Two patients who had painful Schmorl's node at thoracic level from acute trauma were adopted and taken operation for its treatment Objectives : To document the effect of operation for the treatment of painful Schmorl's node at thoracic level summary of background data : Schrmorl's nodes are common spinal lesion generally believed to be asymptomatic, but in some cases there were painful symptom by Schmorl's node. This case report is to explain the effect of operative treatment for the painful Schmorl's node. Methods : Two patients were adopted who had traumatic painful Schmorl's node at thoracic level for our case report. They were treated conservative methods at first but it's effect were poor, so they were taken anterior decompression and fusion, and checked back pain symptom. Result : In all two patients, the symptom of back pain by Schmorl's nodes at thoracic level was almost subsided. conclusion : For the treatment of traumatic painful Schmorl's node, most of surgeon says that conservative treatments were treatment of choice, but operative treatments are also benefit to subsidence of back pain by Schmorl's node.

In routine blood bank, Rh phenotypes including C, c, E, e, were hardly requested and performed. But Rh antibodies causes fetal hydrops, hemolytic anemia, Knowing about the frequencies of Rh phenotypes to find appropriate matched blood is important. Beause the frequencies of Rh phenotypes of Korean were incomplete still, the study for observing Rh phenotypes was performed among the 77,627 blood donors in Daejon Chungnam The results were as follows 1. The incidences. of Rh-D antigen negative were 231 cases(U.3%) respectively among 77,627 donors. 2. The incidences of Rh-Hr antigen were C 88.3%, c 55.3%, E 50.4%, e 90.8% among all Rh-D positive 349 case and C 42.1%, c 93.0%, E 16.7%, e 98.2% among all Rh-D negative 228 case. 3. Rh phenotype of 349 Rh positive and 228 Rh negative blood donors are categorized 15 patterns. And the incidence were CDe 43.3%, CcDEe 37.0%, cDE 8.5%, CcDe 6.3%, cDEe 3.4%, CDEe 1.5%, CcDE 0.3% and cde 48.2%, Ccde 30.3%, cdEe 8.8%. cdE 0.4%. CdEe 1.3%. CcdE 0.4. CdE 0.9%. de 0.4%. In conclusion, Rh phenotypes of Koreans were variable and Rh blood phenotype tests would be a routine blood test to prevent from aloimmunization and hemolytic anemia resulted in Rh mismatch blood transfusion.

저자등은 대동맥판 상부 협착증을 가진 남매의 증례를 통해 가족성 대동맥판 상부 협착증을 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Supravalvular aortic stenosis is a dongenital narrowing of the ascending aorta. The stenotic lesion may be localized or diffuse, originating at the superior margin of the sinuses of Valsalva just above the level of the coronary arteries. This disease is suggested to have familial tendency heredited by an autosomal dominant type of transmission. A 17-years-old male with intermittent exertional chest pain, whose elder sister being a patient with supravalvular aortic stenosis, was admitted for cardiologic evaluation. Diagnosis of supravalvualr aortic stenosis was made by echocardiography, angiocardiography and magnetic resonance imaging of heart. We reported a case of familial supravalvualr aortic stenosis with a review of literature.
