Tissue transplantation is a modern medical technology which develops rapidly and raises many ethical, legal, and political issues. In Korea, many tissue transplantations are performed and many tissue banks seem to be managed. However, there are no legal regulations and standards which control these behaviors. When we discuss tissue transplantations and tissue banking, the safety of tissues, the respect for donors' autonomy, the proper operation of the tissue bank, and the fair distribution of the tissues must be taken into account. And the autonomic regulation by medical professionals must be considered. An Act that controls tissue transplantation and tissue banking must be established, and must be enforced. The Act must be in harmony with the autonomic regulation by medical professionals. The practices that may pose severe risk to human body or threat to human life must be banned, and persons who perform this kind of practices must be punished. However, if the practices remain within the acceptable range, medical professionals can do their practices legally.

The systolic time intervals and hemodynamics were measured in 10 cases of acute anemia and 28 cases of chronic anemia. The measurment was done by non invasive technique, i.e., simultaneous recording of ECG, PCG and carotid and femoral pulse tracing with paper speed 100mm/sec. Compared with healthy persons chronic anemia showed significant reduction of the systolic time intervals except QS1, but the systolic time intervals were unaltered when they were corrected by pulse rate, diastolic pressure and stroke volume. Acute anemia showed decreased of the systolic time intervals except QS1 also the decrease of isovolumic contraction time(ICT) and QS2 when corrected as above. The preejection period(PEP)/left ventricular ejection time(LVET) ratio were not altered. ICT, PEP and PEP/LVET ratio decreased in proportion to the levels of hemoglobin. The heart rate, stroke volume and cardiac output showed significant increase in chronic anemia but mild incease in acute one. The decrease of diastolic pressures and peripheral resistances were more pronounced in chronic anemia than in acute one.

BACKGROUND: A fully automated enzyme-immunoassay (EIA) analyzer, Enzymun System, ES-300 (Boehringer Mannheim, Germany) uses streptavidin technology and performs single test or panels of up to 12 tests per run. We evaluated the results of ES-300 for anti-HCV by comparing the results with microplate-EIA, radioimmunoassay (RIA), and confirmatory test. METHODS: Total 79 sera (51 positive, 24 negative, 4 indeterminate results confirmed by Lucky HCD Confirm) were analysed. ES-300 with Enzymun-Test(R) Anti-HCV (Boehringer Mannheim, Germany) and microplate-EIA (Green Cross Center Innotest HCV 3.0(R)) were used. Fifty one sera were examined additionally by 2nd-generation RIA method, NANBDINE 125C(General Biologicals Corp., R.O.C.). And all results were compared to the results of Lucky HCD Confirm. RESULTS: The overall concordance rate of ES-300 and Innotest(R) was 72/79 (91.1%). The results of Lucky HCD Confirm on seven discrepant samples were five negative and two indeterminate. The results of ES-300 and NANBDINE 125C showed concordance rate of 90.2%. The sensitivity and specificity of ES-300 with regard to Lucky HCD Confirm were 94.5%, and 87.5%, respectively, and that of Innotest(R) were 98.2% and 66.7%, respectively. Clear distinction of positive and negative results by signal/cut off ratio was available in both EIAs. The positive predictive values of ES-300 and Innotest(R) were 94.5%, and 87.1%, respectively. CONCLUSIONS: ES-300 showed relatively good results in sensitivity and positive predictive value with regard to confirmatory test. In EIA-positive persons, however, follow-up study would be necessary for reliable evaluation of HCV infection.

Bilateral coronary artery fistula is very uncommon congenital anomaly which occupy small percentage of all congenital coronary artery fistula. About 20% of the cases associated with additional congenital heart disease. And it may cause congestive heart failure, especially severely in neonate. We experienced a case of neonate who was 1 day-old-male with bilateral coronary artery-right ventricular fistula associated with atrial septal defect and congestive heart failure. The Patient was admitted because dyspnea, cyanosis since birth. 2D ecgicardiogram and cardiac catheterization revealed that a fistulous communicating ; forming a large aneurysm, was noted from bilateral coronary artery emptied into the right ventricle, and there was oxygen step-up in right ventricle.

From January to December of 1990, we have evaluated VDRL reactivity among 17,142 apparently normal Korean adults which consisted of 9,151 blood donors in Seoul area, 2,682 pregnant woman delivered at Severance Hospital, Yonsei University and 5,309 physical examinees. The VDRL-positive rates were 0.3% in the blood donors, 0.1% in the pregnant women and 0.8% in the physical examinees but the rates were higher in the age group of 50 years or older. The VDRL titers were below 1:2 in 94% of the VDRL-positive pregnant women and physical examinees. From the comparison of the results obtained by the present author group since 1977, i.e., 2.5 % in 1977, 1.1 % in 1981, 0.6 % in 1986 and 0.4 % in 1990, it is evident that the prevalence of syphilis in Korea is continually decreasing.

BACKGROUND: Urine ketone test is commonly used to screen for diabetic ketoacidosis (DKA). Ketonuria also develops in patients with disease conditions other than DKA. However, the prevalence of DKA in patients with ketonuria is not known. We investigated the prevalence of ketonuria and characteristics of patients with ketonuria and estimated the prevalence of DKA among them to study the clinical significance of ketonuria as an indicator of DKA. METHODS: We studied 1,314 adult and 1,027 pediatric patients who underwent urinalysis. The prevalence of ketonuria in the different groups of patients, classified according to the types of their visits to the institution, was investigated, and the relationships between ketonuria and albuminuria, glycosuria, and bilirubinuria were evaluated. RESULTS: The overall prevalence of ketonuria was 9.1%. The prevalences of ketonuria in adult and pediatric patients were 4.3% and 15.2%, respectively. The prevalences of ketonuria were the highest in the adult (9.7%) and pediatric (28%) patients in the group that had visited the emergency department. Among patients with ketonuria, 7% adult and 3.8% pediatric patients showed glycosuria. CONCLUSIONS: This study showed that the prevalence of DKA in patients with ketonuria, defined as the simultaneous presence of ketone bodies and glucose in urine, was only 7%. Therefore, we concluded that ketonuria might be clinically significant as an indicator of acute or severe disease status rather than of DKA.
