This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

From June, 1988 to Feb, 1989 a total of 47 cases of percutaneous mitral valve balloon valvuloplasty(PMV) and 4 cases of aortic valve balloon valvuloplasty(PAV) were done at the Guro Hospital of the Korea University. Among these patients first 18 patients of PMV are the subjects of this study. 1) Among a total of 28 patients,10 patients were male and 18 patients were female patients. The age of the patients were between 21 and 59 years with the mean age of 40.9+/-12.2 Aortic Valve ; Atrial Fibrillation ; Balloon Valvuloplasty* ; Blood Pressure ; Cardiac Output ; Cardiac Tamponade ; Catheters ; Drainage ; Electrocardiography ; Embolism ; Female ; Humans ; Korea ; Male ; Middle Cerebral Artery ; Mitral Valve Insufficiency ; Mitral Valve Stenosis* ; Mitral Valve* ; Sepsis ; Thrombosis ; Vascular Resistance

Forty-four cases of abdominal and pelvic computerized tomography (CT) for urological evaluation were reviewed and analyzed as follows: Computerized tomography is a very convenient and non-invasive method to evaluate stages of renal tumor and is more superior in diagnosing hypoplastic kidney and hamartoma than ordinary renal angiography and ultrasonography. Computerized tomography is more informative in evaluation of retroperitoneal space than conventional radiography. It is almost impossible or very difficult to differentiate stage of the bladder tumor A, B1 and B2. Stages beyond C and mass in the pelvic cavity can be detected with relative accuracy. Lymph node metastasis into the retroperitoneal space in testis tumor is diagnosed by computerized tomography.

The species Escherichia coli is a large and heterogeneous group of organisms which is the most common etiologic agent of urinary tract infections. There are some evidences that certain properties are found more commonly in strains from the patients with urinary tract infections than in those from normal feces and in enteropathogenic strains. Twenty eight strains of E. coli from acute pyelonephritis patients and twenty eight strains from a cute cystitis patients were examined for the abilities of adhesion to normal uroepitheliaI cells, hemagglutination, hemolysin production and resistance to the bactericidal effect of normal rabbit serum. For comparison, 20 strains from normal feces and 20 enteropathogenic strains were tested for these properties. The results were as follows; l. The strains from the patients with urinary tract infections adhered in significantly larger numbers to the epithelial cells than those from normal feces and enteropathogenic strains (p<0.0l). 2. The strains from the patients with urinary tract infections induced hemagglutination of human erythrocytes no more frequently than those from normal feces. 3. The strains from acute pyelonephritis patients more commonly produced hemolysin than those from normal feces and enteropathogenic strains. 4. The resistance to the bactericidal effect of normal rabbit serum was higher in the strains from the patients with urinary tract infections than in those from normal feces and enteropathogenic stains. 5. There was no significant mutual relationships among the properties of uroepithelial adhesion, hemaglutination, hemolysin production and serum resistance. From the results the abilities of adhesion to human uroepitheliaI cells, hemolysin production and resistance to the bactericidal effect of normal rabbit serum are supposed to be common properties of uropathogenic Escherichia coli and essential factors in the pathogenesis of urinary tract infections.

Between 1973 and 1983, 64 patients were admitted for renal cell carcinoma at urologic department of S.N.U.H. Twenty four of 64 patients (37.5%) had metastatic disease. Thirteen patients (Group 1) had metastatic renal cell carcinoma on initial presentation and eleven patients (Group 2) had subsequent metastatic lesions after nephrectomy for pathologically early stage cancer. There were 19 men and 5 women ranging in age from 32 to 78 years with an average of 53 years. Average time from tumor presentation to appearance of metastatic lesions in these 11 patients was 11 months and ranged from 2 months to 58 months. The metastatic lesions were found in many different sites including ureter and bladder. Regardless to the method of treatment, most of the patients died within 2 years. The average survival time was longer in Group 2 than in Group 1.
