Congentally corrected transposition of the great vessels can best be defined as a malformation in which the aorta and pulmonary artery are transposed in relation to each other but in which the flow of blood is in the physiologic direction. And in addition to the malposition of great vessels, there is an inversion of the ventrice,. Unfortunately this basic malformation seldom exists withot complicating cardiovascular anomalies. We had experienced a case of congenitally corrected transposition of the great vessels associated with itral?insufficiency in 13year-old boy, who presented the most above mentioned findings. We have made diagnosis by cardiac catheterization and selective angiocardiographic study.

Bacterial endocarditis is a disease with protean manifestations whose presentation has recently changed greatly. Right-sided endocarditis associated with congenital heart lesions is now relatively less common. Patients with ventricular septal defect are at risk for right-sided endocarditis, but its incidence is low in children and adolescents. The organism is frequently a staphylococcus and the clinical course is dominated by septic pulmonary infarction and septicemia. We reported two cases of pulmonic vegetation and pulmonary infarction associated VSD with brief review of literature.

PURPOSE: Although many useful articles appear in the journals published in Korea, they are not always cited by researchers mainly due to absence of efficient searching system. The authors made a program with 6 predefined filtering forms to detect published articles rapidly and accurately. MATERIALS: The program was coded using database management system CA-Clipper Version 5.2 (Computer Associates International, Inc.) through preliminary work for 1 year. We used 486 DX II (8 Mbyte RAM, VGA, 200 MByte Hard Disk), Ink-jet Printer (Hewlett Packard Company), and MS-DOS Version 5.0 (Microsoft Co.). We inputed total of 1986 articles published in the Journal of the Korean Radiological Society from 1981 to 1993. METHODS AND RESULTS: The searching time was 10 to 15 seconds for each use. We had very flexible user interfaces and simplified searching methods, but more complicated filterings could also be performed. CONCLUSION: Although the previous version have had some bugs, this upgrade version resolved the problems and fitted in searching articles. The program would be valuable for radiologist in searching articles published not only in the Journal of the Korean Radiological Society, but also in the Journal of the Korean Society of Medical Ultrasound and the Korean Journal of Nuclear Medicine.

Bronchiolitis obliterans is a distinct pathologic entity, characterized by the accumulation of pigmented macrophages within respiratory bronchioles and adjacent to air spaces, and thickening of the peribronchial interstitium. It has been reported to be associated with viral infection, drug, toxic fume, bone marrow transplantation, and connective tissue disorders such as rheumatoid arthritis. The etiology of bronchiolitis obliterans in the post-renal transplantation state is not yet clear, although several possibilities such as drug toxicity, graft-versus-host disease or postinfectious condition have been postulated. We presented three patient who had bronchiolitis obliterans, as a complication following renal transplantation. Chest radiograph showed bilateral perihilar reticular infiltration or ground glass appearances that progressed to either diffuse alveolar consolidations or solitary nodule. The main finding in each lung biopsy was the presence of macrophages within respiratory bronchioles as well as in the neighboring alveolar ducts and alveoli. Alveolar septa in these areas often showed nonspecific thickening by fibrosis, mild chronic inflammatory cell infiltrate, and hyperplasia of alveolar lining cells and type II pneumocytes.

We present an ultrastructure of an incidentally found renomedullary interstitial tumor also called as medullary fibroma in a 77 year-old female who had a metastatic adenocarcinoma of colon to the ureter. This tumor was a small and grayish white nodule in renal medulla, measuring 0.4 x 0.4 cm. Microscopically the tumor composed of spindle cells, with some vacuolation and intercellular collagen fibers. The electron microscopic observation of the spindle cells reveal that nuclei are spindle to oval shape and cytoplasm contain abundant rough endoplasmic reticulum, polyribosome without microfilaments and cisterna like structures supporting that the renomedullary interstitial cell tumor is renal interstitial cell origin than fibroblasts.

A total or 56 patients who underwent TUR-BT for superficial (stages O and A) bladder tumors received various chemoprophylactic treatment to prevent recurrence. 16 patients underwent resection only (Group I). Of the 56 patients treated with chemoprophylactic agents 18 patients were given thio-tepa at weekly interval for 8 weeks (Group 2). 20 patients were given adriamycin. weekly one time for 6 weeks (Group 3). 16 patients were given mitomycin C, weekly one time for 8 weeks (Group 4). All chemoprophylactic groups were followed by monthly one time for 1 year and the dosages of the used agents (thio-tepa, adriamycin and mitomycin C) were 60 mg/l dosage, 50 mg/l dosage and 30 ml/l dosage, respectively. During follow-up period (mean duration; 19.8-25. 2 months), 1umor recurred 56.2 % of group 1 patients, 27.7 % of group 2 patients, 25.0% of group 3 patients, 18.9 % of group 4 patients and 22.2% of total patients. Therefore three drugs were effective to decrease the recurrence rate of superficial bladder tumor and no significant differences in recurrence rate were noticed among drugs. Toxicity of the three agents were negligibly minimal except 2 patients who developed severe gross hematuria after adriamycin instillation.

PURPOSE: There were many studies on the distributions of the retinal ganglion cells(RGC) in the experimental model of the retinal ischemia. RGC was known to be more sensitive to the ischemic injury than the other types of the retinal cells. So, we would identify the changes of the retinal ganglion cell morphologies and distribution after the iatrogenic retinal ischemia induced by intraocular pressure(IOP) elevation. METHODS: Eight pigmented and six white rabbits were used and retinal ischemia was induced by increasing IOP higher than 120 mmHg for 60 minutes. Electroretinogram were recorded at 6 days or 13 days, and histologic findings were observed at 7 or 14 days. RESULTS: After 7 days, RGC densities decreased, cytoplasmic staining disappeared, and the intranuclear hyperpigmentation was noted. RGC densities decreased significantly at 14 days. In the vertical retinal section, some flattening of retinal ganglion cell layer and inner plexiform layer was observed. Changes in the cellular morphologies were prominent. CONCLUSIONS: It may be more appropriate to examine both the retinal whole-mount and the vertical tissue section for the estimatation of the changes of retinal ganglion cell layer in the pressure-induced retinal ischemia.
