No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

Background : In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. Objective & Methods : For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1997. 99 strains of N. gonorrhoeae were isolated, among which 45(45.5%) were PPNG. Conclusion : The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 45.5% in 1997.

These days, bridges have a tendency to be long-spanned and simple ‘ thus, the importance of economy and efficiency has increased for bridge construction. As a result, one of the main members on which interest is focused is the diaphragms. In this study, stress variation of the support diaphragms in a steel box girder was considered. This paper deals with the behavior of the stress distribution on the diaphragms on the bearings of a closed section steel box girder bridge due to the continuous casting of concrete slab. Both experimental and structural analyses were performed to verify the behavior of the stress distribution a composite steel box girder bridge under construction. Strain was continuously checked at intervals of 10 to 30 min. from the beginning of the placement by the Time Interval Function of the measuring instrument. The variation of strain on the diaphragms on the bearings are presented herein.

This study characterized the genetic variations of 13 populations of Asplenium antiquum and its relative species using randomly amplified polymorphic DNA (RAPD) markers. A total 88 scorable RAPD bands were generated by the 12 random oligo primers and were analyzed by Nei and Li s genetic distance. High genetic variability was detected between A. antiquum and A. nidus, with the range from 0.568 to 0.682. And slightly low genetic variations showed within the populations of same species. Seven populations of A. antiquum showed slight differences (0.000-0.216), and five populations of A. nidus showed similar low genetic variations (0.114 to 0.171). Two individuals from Sup-seom Island which are growing in might be the regenerated one from abroad. A. antiquum were clustered as two groups (Group I, Group II) by UPGMA phenogram. And five populations of A. nidus were clustered as two groups correlated with geographical distribution. The RAPD data was very useful to define the genetic variations and to discuss the phylogenetic relationships among A. antiquum and the related species..

Abstract-Thirteen α-keto acids which are biochemically important were converted to methoxime(MO) derivatives with MOX and then to tert.-butyldimethylsilyl(TBDMS) derivatives using MTBS-TFA in isooctance prior to dual capillary column GC analysis. Single symmetric peaks were obtained for each MO TBDMS α-keto acids on the dual chromatograms. Optimum methoximation required heating at 60℃ for 2 hours and TBDMS derivatization required heating for 30 minutes. MO α-keto acids were stable during the tert.-butyldimethylsilylation and the methoximation of carbonyl group prevented silylation of enols. Mass spectrometric analysis of MO TBDMS derivatives was performed for structure identification. Base peaks at [M-57], intense ions at m/z=89, and weak ions at [M-15] were present in all spectra. The ions at m/z=89 were characteristic for α-keto acids.

저자는 과거 자궁근중으로 수술한 50세 여자 환자가 심부전 및 광범위한 혈전증의증으로 본원에 내원하여 수술후 정맥내 평활근종으로 밝혀진 증례를 경험하였기에 이를 문헌고찰과 함께 보고하는 바이다. A case of intravenous leiomyomatosis (IVL) invading the vena cava and extending to the right atrium, a rare benign smooth-muscle tumor, is described. Despite their histological benignity these lesions have a tendency to metastasize and are closely related to the condition called "benign metastasizing leiomyoma" and " intracaval mass and cardiac extension" a 50-year old woman was admitted to the hospital with dyspnea beginning 6 months ago and precious history of hysterectomy due to uterne myoma. Echocardiography revealed severe tricupid valve insufficiency and a mobile elongated mass which occupied the inferior vena cava and was extending into the right ventricular cavity. Pelvic ultrasonography and pelvic MRI identified suspicious metastasis to both ovaries and peritoneum. She underwent resection of the cardiac tumor, conomitant tricuspid annuloplasty with a closure of the foramen ovale and both salphyngo-oophorectomy with vaginal stump mass biopsy. All of them could be histologically identified as IVL.

The present study was to evaluate the treatment efficacy in a Coping With Depression Curse (psychoeducational group treatment) for unipolar depression among college students. The Coping with Depression Course constructed by Lewinsohn (1979) is based on the social learning theory analyzing depression. It is assumed to be associated with a decrease in pleasant and an increase in unpleasant person-environment interactions. Following these theoretical notions, the goal of treatment (CWD) is to Set the new self-changing skills : relaxation, Pleasant activities, constructive thinking, and social skills. In order to get the changes of the six participants, there were given pre- and post- tests which were consisted of MMPI-D, SCL-D, and BDI tests. According to the results of these tests, there were significant changes between scores on the pre- and post- test. Generally, those results were supported that CWD was an effective program to treat unipolar depression among college students.
