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.

The congenital diverticulum of ventricle is a rare cardiac malformation arising from the left or right ventricle, the former being more common. Ventricular diverticulum is usually associated with other anomalies including intracardiac, midline thoracic, diaphragmatic and abdominal wall defect. The authors experienced a case of congenital diverticulum of left ventricle in nine month-old female infant. Left Blolock-Taussig shunt operation was done and total correction will be done later. Thereafter we presented a case with brief review of the related literatures.

To investigate the effects of maternal hyperthermia on the development of the palate, pregnant Hsp70 knock-out mice at gestational day (GD) 8.5 were immersed in 43degrees C water bath until their body core temperature reached at 43degrees C. Thereafter, pregnant mice were given more 5 minutes hyperthermic exposure. Heat-untreated Hsp70 WT mice fetuses were used as the control group. Fetuses were collected at embryonic day 13.5, 14.5 and 15.5 (E13.5, E14, 5 and E15.5). Heads followed by removal of the mandible and the tongue were obtained and photographed for palatal development. Developing palates were processed for histological and immunohistochemical studies. Tissue sections were immunostained for TGF-beta2, FGF-8 and fibronectin, and observed with light microscope. The obtained results were as follows: Cleft palate was formed in heat-treated Hsp70 KO fetuses at E14.5 and E15.5. Immunohistochemical findings indicated that TGF-beta2 expression of the experimental fetuses were more delayed than that of the control fetuses. Mesenchyme under the medial edge epithelium (MEE) and cells of MEE showed continuously strong positive TGF-beta2 reactivity at E15.5. FGF-8 was revealed in both of the mesenchyme and the epithelium at the same time. FGF-8 immunoreactivity in the mesenchyme and the epithelium of the heat-treated fetuses showed strong reactivity at E15.5. In the experimental fetuses fibronectin was revealed the mesenchyma and basal lamina at E15.5. Taken together, it is suggested that maternal hyperthermia induces continuous expression of TGF-beta2 and FGF-8 in the mesenchyme and delayed expression of fibronectin. These should affect the normal palatogenesis and result in cleft palate.

BACKGROUND: The human homologue of the SC2 gene from a human dermal papilla cell cDNA library has been isolated and designated hSC2. HSC2 protein also shares similarity with 5 -reductase, a protein important in testosterone metabolism. OBJECTIVE: Prior to knowing the functions of hSC2 in dermal papilla, we cloned it and analyzed its relative expression levels in adult tissues and cancer cell lines. METHODS: hSC2 was isolated from low abundant clones in dermal papilla cDNA library using cDNA array hibridization method. Full-length clone was sequenced and we studied its expression in different tissues by Northern blot hybridization. RESULTS: Sequence data reveals a single open reading frame, encoding a putative hydrophobic protein with a calculated molecular weight of 36 kDa. Its deduced amino acid sequences are almost 97.4% identical to t4ose of rat protein. Northern blot hybridization shows that hSC2 cDNA recognizes a 1.35 kb transcript that was expressed in various epithelial and mesenchymal tissues including testis and liver. CONCLUSION: We have cloned and analysed tissue distributions of hSC2. It was interesting that it had homology with 5α-reductase isozymes. Further studies will be needed to understand the involvement of hSC2 in androgen hormone signaling.
