A prospective study of vitamin B6, B12, folate, and homocysteine levels was carried out in 7 kidney transplant(KT) recipients. The first sample for the basal level was drawn on the morning of the KT day before the start of cyclosporine injection. Thereafter, serial blood samples were taken every day until the serum creatinine level decreased below 1.5 mg/dl and then every 2 or 3days until discharge. The serum creatinine level decreased to below 1.5 mg/dl within 3days except for cases 4 and 6. The homocysteine levels decreased markedly in synchronisation with serum creatinine levels increased during the first 7days and then declined together with serum creatinine levels but went up again after a few days. The levels of B6, and vitamin B12 do not continue to decrease after the levels of serum creatinine have decreased to 1.5mg/dl, while homocysteine levels go up progressively. In conclusion, contrary to our expectation, the level of homocysteine rebounds a few days after KT following a transient decline. A deficiency of folic acid, vitamin B6 and vitamin B12 does not seem to cause hyperhomocysteinemia in KT recipients. It is necessary to pay attention to hyperhomocysteinemia in KT recipients, especially when the recipients have an atherosclerosis-related complication.

The normal vascularization of peripheral nervesand the vascular factor in peripheral nerve les ons have regained increasing interest among surgeons. So, several attempts have been made to assess the relative importance of the vasa nervorum and intrinsic longitudinal vascular plexuses of nerve in maintaining the blood supply.of a segment of nerve trunk. The purpose of our experiment was to determine in laboratory animals the maximum extent to which a nerve can be mobilized without impairing its vascular supply so much that nerve function is jeopardized. All our studies were carried out on both sides of the sciatic-tibial nerve of thirty-two rabbit which were anesthetized intraperitoneally with urethane. The experimental procedure differed in three groups, Group I in which the sciatic nerve was mobilized 3 cm in length, Group II was mob lized 7 cm length and Group III was mobilized 10cm long. The tibialis post. muscles of each group were analyzed at intervals ot 1,2,4,6 and 8 weeks after neurolysis. Each muscles were examined grossly and histologically after hematoxylin and eosin staining. Experimental studies showed that a peripheral nerve is a well vascularized structure with a considerable reserve capacity in its microirculation. The intrinsic collateral system is well developeed and experimental deta supported the view that peripheral nerves may be mobilized over a cons derable length with or the only minium interference with their microvascular flow. The results were as follows: 1. The first evidence of histologic change in the muscle fibers was in the sarcolemmal neclei. 2. Localized atrophy of muscle fibers were observed at the six weeks after neurolysis. 3. With increasing length of neurolysis, abnormal finding were developed in early stage. 4. Massive atrophy of muscle fibers were noted in the muscle fibers which neurolysed more 7cm.

Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

Id (Inhibitor of Differentiation) proteins belong to a family of transcriptional modulators that are characterized by a helix loop helix (HLH) region but lack the basic amino acid domain. Id proteins are known to interact with basic helix-loop-helix (bHLH) transcription factors and function as their negative regulators. The negative role of Id proteins has been well demonstrated in muscle development and some in neuronal cells. In this study, we investigated the effect of Id on the function of BETA2/NeuroD, a bHLH transcription factor responsible for neuron and endocrine cell specific gene expression. cDNAs of several Id isoforms were isolated by yeast two-hybrid system using the bHLH domain of E47, a ubiquitous bHLH partner as a bait. Id proteins expressed in COS M6 cells, were found in both cytosolic and nuclear fractions. Electrophoretic mobility shift assay showed that coexpression of Id2 proteins inhibited BETA2/ NeuroD binding to its target sequence, E-box. Id2 inhibited E-box mediated gene expression in a dose dependent manner in BETA2/NeuroD expressing HIT cells. Id coexpressed with BETA2/NeuroD in HeLa cells, inhibited the stimulatory activity of BETA2/NeuroD. These results suggest that Id proteins may negatively regulate tissue specific gene expression induced by BETA2/NeuroD in neuroendocrine cells and the inhibitory role of Id proteins during differentiation may be conserved in various tissues.

OBJECTIVES: This study was performed to study the way of thinking and satisfaction level of North Korean defectors in South Korea on various topics and their relationship with each other. METHODS: Direct interview was performed for 553 North Korean defectors in South Korea. 44 items of life satisfaction were rated. Satisfaction level was rated on a 5 point scale (1-unsatisfactory and 5-fully satisfied). Factor analysis and correlation of the factors were performed. RESULTS: The average level of satisfaction was 3.39. Relatively high satisfaction items were adjustment of their children, family life, and residence area. But relatively low satisfaction items were psychological and mental area, leisure, and income. In governmental support systems, medical support was the most satisfactorily rated item, but financial support for settlement and support for employment or job training were the most dissatisfied. In the factor analysis, 44 items of satisfaction were grouped into 13 factors. The correlation of these factors showed that general satisfaction is significantly correlated with satisfaction with housing, economic status, governmental support and lower degree of confusion on the sense of value. Confusion on the sense of value was high when defectors do not have close friends, have difficulties in understanding South Korean people, and are not satisfied with their economic status. Religion did not have significant correlation with the their sense of value. And self and social consciousness of the defectors were strongly correlated with the their employment status. CONCLUSION: This result showed that the satisfaction of North Korean defectors is correlated not only with material aspects, but also psychological and mental aspects. The results of study should be considered in helping defector to adjust to living in South Korea.
