The induction of cellular and humoral immunity and cytokine gene expression by synthetic CpG oligodexoynucleotides (CpG-ODNs) has not been investigated systematically in olive flounder Paralichthys olivaceus in vivo. We optimized the proper concentration of CpG-ODNs using an in vitro assay for the superoxide anion $(O_2^-)$. CpG-ODNs induced $O_2^-$ and nitric oxide (NO) production, lysozyme activity, and the proinflammatory cytokine gene expression of $IL-1{\beta}$ and $TNF-{\alpha}$ in olive flounder significantly in vivo, whereas non-CpG-ODNs did not produce these effects or produced them to a lesser extent. This implied that CpG-ODNs could stimulate cellular and humoral immunity and cytokine gene expression in olive flounder. This is the first evidence of NO production and the first study on the mRNA expression of the proinflammatory cytokine genes $IL-1{\beta}$ and $TNF-{\alpha}$ in olive flounder in response to CpG-ODNs. Comparison of the variation in NO production and lysozyme activity to that of other studies led us to postulate that a group-specific difference exists in the immune responses of olive flounder against CpG-ODNs. Furthermore, the detailed immunostimulatory spectrum of CpG-ODNs in olive flounder could be a useful index with which to analyze the effect of CpG-ODNs against the challenge test prior to field applications.

This paper analyzes arc phenomena including the secondary arcs elongation in theKorean 765kV single transmission line (79km) between Sin-Ansung S/S and Sin-Gapyeong S/S, which dependent line models are compared to make our final decisions. As wel, the significant simulation results are investigated by the EMTP program. As a result, there is no need of HSGS in the Korean 765kV single transmission line from both a practical and an economical point of view.
Fatigue experiment of stud welded on steel plate for a new bridge deck system

This paper presents push-out tests of stud shear connectors to examine their fatigue behavior for developing a new composite bridge deck system. The fifteen push-out specimens of D16 mm stud welded on 9 mm steel plate were fabricated according to Eurocode-4, and a series of fatigue endurance test and residual strength test were performed. Additionally, the stiffness and strength variations by cyclic loading were compared. The push-out test, when the stiffness reduction ratio of the specimens was 0.95 under cyclic load, resulted in the failure of the studs. The stiffness variation of the push-out specimens additionally showed that the application of cyclic loads reduced the residual strength. The fatigue strength of the shear connectors were compared with the design values specified in the Eurocode-4, ASSHTO LRFD and JSSC codes. The comparison result showed that the fatigue endurance of the specimens satisfies the design values of these codes.

<P>In order to understand the mechanisms underlying plant development, a necessary first step involves the elucidation of the functions of the genes, via the analysis of mutants that exhibit developmental defects. In this study, an activation tagging mutant library harboring 80,650 independent <I>Arabidopsis</I> transformants was generated in order to screen for developmental mutants. A total of 129 mutants manifesting dominant developmental abnormalities were isolated, and their T-DNA insertion loci were mapped. The activation of one or more genes adjacent to a T-DNA insertion locus was confirmed in eight dominant mutants. A gene adjacent to the right border was usually activated by the 35S enhancers. Interestingly, the transcriptional activation of multiple genes within a broad range was observed in one of the mutants, which raises the possibility that activation by the 35S enhancers was not limited strictly to a single gene. In order to gain a better understanding of sexual reproduction in higher plants, we isolated 22 mutants exhibiting defects in female gametophyte development, and determined their T-DNA insertion loci. We propose that this mutant population may prove useful in the further determination of the functions of genes that play important roles in plant development.</P>

<P>The clinical outcomes of 2,054 renal recipients were examined retrospectively based on pre-transplant hepatitis B surface antigen (HBsAg) status to investigate the efficacy of lamivudine treatment in HBsAg positive recipients. Pre-transplant HBsAg positivity was documented in 66 recipients. The 10-year patient and graft survival rates in Ag positive group were significantly lower than those of Ag negative group (64.4/36.6% vs. 88.2/70.5%, respectively, P < 0.0001). Since 1997, lamivudine was used when hepatitis B virus polymerase chain reaction (HBV PCR) was positive or when the level of post-transplant viral load rose. Lamivudine given to 27 recipients markedly improved both 10-year patient and graft survivals compared to Ag positive renal recipients who did not take lamivudine (85.3/59.2% vs. 49.9/22.7%, respectively, P < 0.0001). Overall, 13 viral breakthroughs among 24 lamivudine-responsive patients were observed. The cumulative incidence of viral breakthrough at 60 months was 53.3%. Adefovir rescue in three viral breakthroughs patients induces virological response and restoration of liver function. In 10 patients who did not changed to adefovir, 6 patients are alive with elevated liver enzymes. In conclusion, in the era of lamivudine and adefovir, renal transplantation in HBsAg positive end-stage renal disease patients should not be abandoned. J. Med.

<P>Erosions of the bone and cartilage are considered as a cardinal feature of rheumatoid arthritis (RA) leading to joint destruction and functional limitations. This report is a radiologic observation of distinguishable bone erosion repair with concomitant increase of radio-opacity of trabecular bones after 15 months of antitumor necrosis factor (TNF) antibody adalimumab therapy in a 26-year-old woman with RA resistant to conventional therapy. Although the introduction of anti-TNF antibodies has contributed to the slowing and arrest of RA progression, destruction itself has been generally acknowledged as an irreversible process with little hope (only 1.8% of erosions) in resolution. Our patient's dramatic structural retrieval is a discrepant, yet notable case pivoting the previous belief on the skeletal restoration capacity of anti-TNF antibody into a circulating cytokine-dependent manner.</P>

This paper analyzes arc phenomena including the secondary arc's elongation in the Korean 765kV single transmission line (79km) between Sin-Ansung S/S and Sin-Gapyeong S/S, which will be installed in Korea in June 2006. In particular, both frequency independent and frequency dependent line models are compared to make our final decisions. As well, the significant simulation results are investigated by the EMTP program. As a result, there is no need of HSGS in the Korean 765kV single transmission line from both a practical and an economical point of view.
