A case of a 58-year-old man with malignant fibrous histiocytoma (MFH) of the right ventricle is reported light and electron microscopically. This is the first case of MFH of the heart in the Korean literature. A tendency for malignant fibrous histiocytoma of the heart to occur in the left atrium of young women is suggested; this sarcoma's usual location is in the soft tissue of elderly men. The tumor consisted of spindle cells arranged in a focal storiform patterns, clusters or sheets of histocyte-like cells, benign and malignant giant cells, inflammatory cells, scattered mitotic figures and anaplasia of stromal cells. In ultrastructure the constituent of cells of the tumor are primitive mesenchymal cells, histiocytoid cells and fibroblast like cells including giant cells.

Since the identification of the C-group chromosome has been made possible by the introduction of banding technique, the features of the trisomy-8 syndrome have been defined. Most of them have been mosaics and have had similar clinical findings. A case of Trisomy-8 mosaicism confirmed by G-banding analysis by skin fibroblast and heart blood in a dead female fetus of 35 weeks of gestation is described.

PURPOSE: To assess the role of MRI in the diagnosis of uterine anomaly. MATERIAL AND METHODS: MRI(n:15), hysterosalpingography(n:7) and ultrasonography(n:7) were performed in 15 patients with suspected MullerJan duct anomaly. Nine cases were proved by operation and six cases were diagnoed with imaging and clinical findings. According to Buttram and Gibbons modified classification, the anomalies were 4 cases of class I, 2 cases of class III, one case of class IV, and 8 cases of class V. RESULTS: MRI enabled accurate diagnoses of anomalies in all cases, but HSG and USG showed wrong diagnoses in 3 of 7 cases and in 1 of 7 cases. CONCLUSION: MRI, especially T2-weighted images parallel to long axis of uterine corpus, was very useful in diagnosis of the Mullerian duct anomaly, because it could depict exactly the external fundal contour, intercornual distance, septum, transverse vaginal septum, and associated abnormalities such as hematocolpos and hematometra.

This stydy was undertaken to evaluate the cephalometric changes of the soft tissue and skeletal profile subsequent to the palatal expansion in 25 Angle's Class III cases, ranging in age from six to fifteen years, with cross-bite of the anterior teeth, underdevelopment of maxilla and facial disharmony. Following results were obtained: 1. ANS moved downward, Point A presented forward & downward movement increasing SNA and point B presented backward & downward movement decreasing SNB. 2. Mandible was rotated to backward & forward and maxilla moved forward & downward with the bite opening and improvement of anterior teeth cross-bite. 3. Soft tissue on inadible was rotated to backward & downward rotation of Point B', Pog'. 4. Respones of the upper lip was more significant in downward than forward direction, and correlated with the upper central incisor and mandible rotation. 5. Reaponse of the lower lip was mord significant in downward than backward direction, and correlated with the mandible rotation. 6. There was a rather high degree of correlation between skeletal porfile and soft-tissue profile, :LS, 1:Pog', Pog:LS, Pog:LI:Pog' in horizontal measurements and 1:Pog', Pog:LI, Pog:Pog' in vertical measurements.

Distributions trends were examined in 9159 malocclusion patients had been examined and diagnosed at Department of Orthodontics, College of Dentistry, Yonsei University over a 6 year-period from 1992 to 1997. The results were as follows: 1. The total number of orthodontic patients in 1997 increased in comparing with that of 1992(86%)and after 1995, the number of annual patients showed an increase. 2. Age distribution had shown over-19 year-old group being the largest(39.9%) but percentages of pre-adolescent patients had been decreasing while that of adult patient had gradually increased. 3. Distributions in the types of malocclusion, the Angle's Classification had shown : 33. 3% for Class I, 28.6% for ClassII and the largest 38.1% for Class III. 4. Among Class I patients, crowding showed the largest(32.6%) and protrusion group had gradually increased to 33.9% in 1996. Otherwise openbite and groups tend to decrease, annually. 5. Geographic distribution showed a majority of patients from Seoul(above 70%). Among the patients from Seoul, group within the distance 3-6km from Yonsei dental hospital was the largest(32.3%) and group within 9km showed 69% of total patients.

We developed the BaSDAS (Barcode-Seq Data Analysis System), a GUI-based pooled knockout screening data analysis system, to facilitate the analysis of pooled knockout screen data easily and effectively by researchers with limited bioinformatics skills. The BaSDAS supports the analysis of various pooled screening libraries, including yeast, human, and mouse libraries, and provides many useful statistical and visualization functions with a user-friendly web interface for convenience. We expect that BaSDAS will be a useful tool for the analysis of genome-wide screening data and will support the development of novel drugs based on functional genomics information.
