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.

■ Purpose To report a technique of vertebral column resection through a single posterior approach and its first results in the treatment of severe spinal deformities. ■ Methods and materials Seventy spinal deformity patients treated by posterior vertebral column resection(PVCR) were reviewed. Minimum follow up was 2 years (2 - 3.3 years). There were 34 males and 36 females with a mean age of 27.4 years at the time of the operation. Etiologic diagnoses were adult scoliosis in 7, congenital kyphoscoliosis in 38, and post-infectious kyphosis in 25. The surgery consisted of temporary stabilization of the vertebral column with segmental pedicle screw fixation, resection of the vertebral column at the apex of the deformity via the posterior route followed by gradual deformity correction and global fusion. ■ Results The total number of resected vertebrae were 143; 76 in thoracic and 67 in lumbar. Mean operation time was 4 hours 31 minutes with average blood loss of 2333 ml. The deformity correction was 40o in the coronal plane and 5Oo in the sagiotal plane. Complications were encountered in 24 patients: 2 complete cord injuries in severe adult scoliosis and thoracic kyphosis patient who had significant preoperative cord compromise, 6 hematomas, 4 root injuries (all incomplete), 5 fixation failures, 2 infections and 5 hemopneumothoraxes. ■ Conclusions PVCR is an effective alternative for severe fixed spinal deformities. However, extreme caution must be taken in the patients with preoperative cord compromise who are the high risk of neurological complications.

Objective : To report the clinical result of segmental pedicle screw fixation and translation technique in surgical correction of idiopathic scoliosis. Methods and materials : Ten idiopathic scoliosis. patients treated with segmental pedicle screw fixation and translation technique were analyzed retrospectively. The mean follow-up interval was 23.8months, with a minimum of 12 months. Eighteen structural curves were fused in one double curves(King type Ⅰ), seven double thoracic curve(King type Ⅴ) and two thoracolumbar curve. Deformity correction, apical vertebral rotation(AVR), apical vertebral translation(AVT), trunk balance, shoulder balance and complications were evaluated. Result : The structural curve was corrected from 47.4±10.6° to 20.3±5.9° at 1week after surgery and 55.6±14.1° at latest follow-up. AVR was corrected from 2.06±0.4 to 0.94±0.41 at 1week after surgery and latest follow-up. AVT was improved from 25±15.7㎜ to 11.5±7.3㎜ at 1week after surgery and 12.3±7.3㎜ at latest follow-up. There were no trunk imbalance(less than 10㎜ distance from C7 plumb line), no shoulder imbalance(less than 10㎜ shoulder height difference) and no screw related complications. Conclusions : The segmental pedicle screw fixation and translation technique is an effective method in treating for idiopathic scoliosis.

Reconstruction of the penis is indicated in a traumatic or surgical amputation, congenital penile absence, micropenis, male pseudohermaproditism, or transsexualism. Initially, penile reconstruction has been performed using a local flap, but often failed because of the multiple procedures, fistula or stricture of the urethra, and no sensation of the phallus. Ideally, penile reconstruction should be a one-stage procedure, creating a phallus with both tactile and aerogenous sensibility, water-tight neourethra allowing for voiding while standing, enough bulk with stiffness, and aesthetically acceptable appearance. Since August 1989 we have constructed a penis in 4 patients. We selected the radial forearm flap as a donor site because it offers a reliable artery, veins, nerves, and stiffner. It also offers thin, malleable skin with adequate width and length. We have followed these patients from 5 months to 10 months. All operations were successful except for one fistula formation.

The ballet, as a representative genre of theatrical art, has developed with constant opposition between dramatic ballet laying emphasis upon its dramatic characteristics and plotless ballet putting stress on integrity of dance. In this respect, this study attempts to investigate some types of ballet with its brief historical survey. Jean George Noverre(1727-1810), a historical father of dramatic ballet, insisted union of dancing and drama on the basis of his theory "ballet diction". Mikhail Fokin(1880-1942) in the early 20th century, experiments a possibility of "new ballet" with a stress upon synthesis of ballet, completing its "five principles" and he values human's inner emotion and its expression above everything else. In the mid 20th century, Antony Tudor(1908-1987), a successor of M. Fokine's spirit, raised up the level of formal characteristics of dramatic ballet, creating a genre called "psychological ballet". In addition, Kurt Joose(1901-1979) and John Granko(1927-1973) created a structural characteristic of dramatic ballet. Its main contents are as follows : First, plot, a composition of story required to dramatic ballet, is an essential requirement providing the inner order of work. Second, persons or characters are the main element developing story, Third, action is only direct means to understand persons, and prior to others. Fourth, uniting all expressive elements of theatrical art make sure the synthetic feature which dramatic ballet is pursing as a total art. In conclusion, it can be expected in this study that the formal features of dramatic ballet and its types according to the times would be recognized and received more seriusly and deeply in understanding and producing ballet.
