There was no definitive reported cases of urinary calculi. This study is to estate the value of urinary calcium, magnesium, uric acid and magnesium/calcium ratio in cases of urinary calculi. The amount of calcium, uric acid and magnesium in 24 hour urinary excretion was measured by OCPC, Uricase and titan yellow method in 56 cases of upper urinary calculi compared with 35 control group.The results were summerized as follows.l. The mean values of 24 hour urinary excretion of calcium were 193+/-26mg/day in stone formers and 15l+/-25mg/day in control group. The 24 hour urinary excretion of calcium in the stone formers were significantly higher than those of the control group. 2. The mean values of 24 hour urinary excretion of uric acid were 498+/-40mg/day in the stone formers and 371+/-6mg/day in the control group. The 24 hour urinary excretion of uric acid in the stone formers were significantly higher than those of the control group. 3. Urinary magnesium values have not been shown any significant differences between the group with urinary calculi and those of control group. 4. The mean values of 24 hour urine of magnesium to calcium ratio was 1.01+/-0.95 in stone formers and l.42+/-1.31 in the control group. The magnesium to calcium ratio in the stone formers were significantly lower than those of the control group. These results suggest that increased urinary calcium and uric acid level may play some role in the genesis of urinary stone but urinary magnesium value was not different in the two groups. We think that a decrease in the urinary magnesium to calcium ratio was the results of increased excretion of calcium rather than lowered excretion of the magnesium for the stone formers.

A clinical observation was made on the case of pediatric urological disease who had been admitted to the Department of Urology, Korea University Hospital during the period of 8 years and one month from September 1, 1972 to September 30, 1980. 1) Of 1977 cases hospitalized in the GU Dept., 229 cases were pediatric urological patient giving a rare of 11.5% and the ratio between male and female was 5.8:1. 2) The most commonly involved organ was, scrotal contents (31. 6%). Urethral diseases were 23. 6%, penile diseases 13.6%, and renal diseases 12.4%. 3) The most common diseases were genito-urinary anomalies (62. 8%). The injuries of G-U tract were 22%, nonspecific infections 7.6%, V-U reflux 4.8%, urinary lithiasis 4%. 4) The most common symptom and sign were absence of scrotal contents in 48 cases. Abnormal position of urethral meatus was seen in 36 case, Scrotal swelling in 23 cases, curved penile shaft in 16 cases, flank pain in 15 cases. 5) Operation was performed in 176 cases (76. 9%). 6) Orchiopexy was performed in 43 cases (24. 4%), circumcision in 42 cases (23. 9%), urerhroplasty in 16 cases (9.1 %), hydrocelectomy in 41 cases (8%), chordectomy in 13 cases (24 %).

STATEMENT OF PROBLEM: Zirconia-based restorations have the common technical complication of delamination, or porcelain chipping, from the zirconia core. Thus the shear bond strength between the zirconia core and the veneering porcelain requires investigation in order to facilitate the material's clinical use. PURPOSE: The purpose of this study was to evaluate the bonding strength of the porcelain veneer to the zirconia core and to other various metal alloys (high noble metal alloy and base metal alloy). MATERIAL AND METHODS: 15 rectangular (4x4x9mm) specimens each of zirconia (Cercon), base metal alloy (Tillite), high noble metal alloy (Degudent H) were fabricated for the shear bond strength test. The veneering porcelain recommended by the manufacturer for each type of material was fired to the core in thickness of 3mm. After firing, the specimens were embedded in the PTFE mold, placed on a mounting jig, and subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.5mm/min until fracture. The average shear strength (MPa) was analyzed with the one-way ANOVA and the Tukey's test (alpha= .05). The fractured specimens were examined using SEM and EDX to determine the failure pattern. RESULTS: The mean shear strength (+/- SD) in MPa was 25.43 (+/- 3.12) in the zirconia group, 35.87 (+/- 4.23) in the base metal group, 38.00 (+/- 5.23) in the high noble metal group. The ANOVA showed a significant difference among groups, and the Tukey's test presented a significant difference between the zirconia group and the metal group. Microscopic examination showed that the failure primarily occurred near the interface with the residual veneering porcelain remaining on the core. CONCLUSION: There was a significant difference between the metal ceramic and zirconia ceramic group in shear bond strength. There was no significant difference between the base metal alloy and the high noble metal alloy.

Xanthogranulomatous pyelonephritis is an atypical form of severe renal parenchymal infection, characterized by yellow lobulated masses macroscopically and massive inflammatory cell, foamy histiocyte microscopically. Preoperative diagnosis confused with hypernephroma, pyonephrosis with stone, other renal inflammatory disease. We report two cases of xanthogranulomatous pyelonephritis, diagnosed by microscopical finding and literature has been reviewed briefly.

BACKGROUND: The oral ulcer is a common oral disorder, but the precise etiology remains elusive despite of intensive clinical, immunological, hematological and microbiological investigations. OBJECTIVE: The purpose of this study was to examine oral ulcers for the detection of HSV DNA by using PCR and to characterize clinical features of HSV DNA positive cases. METHODS: Specimens collected with cotton swabs and saliva from 48 cases of oral ulcers were examined for HSV DNA by PCR and Southern blot hybridization. RESULTS: 1. HSV DNA was detected in 8 of 48(16.7%) cotton swabbed specimens of oral ulcers and saliva by PCR and Southern blot hybridization. 2. Clinical features of HSV DNA positive oral ulcers were a. predominently located in buccal mucosa. b. mall sized(<3mm), multiple(> or =5) lesions. 3. In Behcet's disease, 2 of 7(28.6%) cases of oral ulcers were positive for HSV DNA CONCLUSION: PCR is an useful and accurate method for the detection of HSV DNA from cotton swabbed specimens of oral ulcers.

To evaluate the degree and development of complication of renal trauma multiple studies my be necessary, including urography, sonography, CT scan and renal scan. We appreciated the usefulness and outcome of sonography in evaluation of renal trauma through the experiences of its applications to 5 renal trauma patients. Our experiences demonstrate follows : 1. In all 5 patients, sonography detected the presence and change of perirenal hematoma and cortical laceration successfully. 2. In one patient who developed into non-functioning kidney, sonography played little one. 3. Sonography seemed to be a relatively reliable modality of guidance in follow-up of major and minor renal trauma patients who were going to manage conservatively.

We report a case of focal eosinophilic myositis of the frontalis muscle in a 38-year-old man. The skin lesion was a single firm flesh-colored swollen lesion measuring 1×1.5 cm in size on the right forehead. The biopsy revealed inflammatory infiltrates composed of mainly eosinophils and a few lymphocytes in the muscles. The skin lesion subsided with intralesional injections of triamcinolone acetonide, 5 mg/ml.

Inverted papilloma of the urinary tract is a unique and rare tumor. It is generally considered a benign lesion, although previous reports have alluded to the possibility of malignant change. The lesion is believed to arise mainly from trigon and bladder outlet as a result of chronic. proliferative cystitis. The most commonly associated clinical symptoms are hematuria and those of urinary obstruction. We report two cases of vesical inverted papilloma which were proved histologically.
