Authors performed the chordectomy using Blair, Byars and Glenn-Anderson method, the urethroplasty with Denis-Browne-Crawford method and one-stage repair of hypospadia with Allen-Spence method. The following results are obtained from 40 cases of urethroplasty and 10 cases of one-stage repair of hypospadia which were done in the Department of Urology, Busan National Univ. Hospital during recent 7 yrs (71~77). The results were as follows : 1. The most common age group of hypospadia was observed in 11-20 year old (40.0 %) and that of less than 5 year old was only 12.0 %. 2. The most common type of hypospadia was observed in ponoscrotal type (26.0 %) while the hypospadia without chordee was 2.0 %. 3. The most common anomaly associated with hypospadia was cryptorchism (40.0 %). 4. Average of the period of postoperative hospitalization was 9.5 days in chordectomy. 10.8 days in urethroplasty and 10.2 days in one-stage repair of hypospadia. The interval between chordectomy and urethroplasty was 13.9 months. 5. Average of the period of postoperative urethral catheterization was 7.6 days in chordectomy, 3.2 days in urethroplasty and 7.5 days in one-stage repair of hypospadia. 6. The postoperative complications were 2 cases of persistent chordee in Blair method, 1 case of fistula and 3 cases of stricture in Denis-Drowne-Crawford urethroplasty and 2 cases of fistula in one-stage repair of hypospadia. The success rate was 91.9 % in Blair method. 100 % in Byars method and Glenn-Anderson method, 90.0 % in Denis-Browne-Crawford urethroplasty and 80.0 % in one stage repair of hypospadia.

In this investigation, the bladder of guinea pig was longitudinally mounted in the muscle chamber and contracted by electrical field stimulation(EFS). It was purposed to elucidate the physiological significance of prostaglandin(PG) on the neurotransmitter release from nerve ending. 1. The inhibitory response of 5 x 0.0000001 g/ml atropine was significant only by high frequency (p<0.05) However. the curve of frequency-response were shifted to left upward by 5 x 0.00000001 g/ml phentolamine, it were not significant. Because the contraction was completely abolished by 0.00000001 and 0.0000001g/ml tetrodotoxin, it was evident that the responses to electrical stimulation are entirely due to nerve mediated excitation. 2. The curve of frequency-response were significantly shifted to left upward by 5x 0.00000001 and 5x0.0000001 g/ml arachidonic acid(p<0.05). Though the contraction were inhibited by 5x0.0000001g/ml atropine it was not significant. 3. The curves of frequency-response showed dose-response relation by 5x 0.00000001, 5 x0.000000001 and 5x 0.0000000001g/ml PGE2. The contraction was significant only by high frequency in 5x0.0000000001g/ml PGE. and the frequency-response curves were significant in varying frequencies in 5x0.000000001and 5x0.00000001g/ml PGE2(p<0.05). 4. Although the contraction was found by 5x0.0001g/ml aspirin, the curves of frequency-response were not significant. The contraction by 5x 0.0001g/ml aspirin and 5x0.000001/ml arachidonic acid was not significant too.

Small cell osteosarcoma is a rare form of osteosarcoma and the histological differential diagnosis from other small round cell tumors (SRCTs) is difficult. The immunohistochemical stain for MIC2 has been considered an useful diagnostic marker for Ewing's sarcoma and primitive neuroectodermal tumors but recently, other SRCTs such as malignant lymphoma and embryonal rhabdomyosarcoma also showed positive reaction. Therefore, the usefulness of MIC2 must still be proven. We experienced a case of small cell osteosarcoma of the mandible in a 25-year-old man. Histologically, the tumor consisted of small round cells that resembled those of Ewing's sarcoma. Immunohistochemically, the tumor cells expressed diffuse strong positive reaction for MIC2 gene products. However, the scanty foci of lacy osteoid material between the tumor cells seemed to be diagnostic of osteosarcoma. The histologic and immunohistochemical findings of this case suggest close relationship between small cell osteosarcoma and Ewing's sarcoma.

The authors carried out the cystoplasty by regeneration to a 24 year-old female of tuberculous contracted bladder with artificial bladder. The artificial bladder was prepared by using nobecutane-sprayed paper, which was designed by repetition of Nobecutane spraying and drying. The artificial bladder was subjected to a crucial incision on the dome and a No. 10 porous catheter was inserted from the urethra into the bladder. The artificial bladder was sutured with the original incised one with a margin of 1 Cm using 3-0 chromic catgut. The authors observed for 2 months postoperatively. The following results were obtained. 1. The artificial bladder fell off completely in the bladder in 34 days after the cystoplasty, which was extirpated transurethrally. 2. The bladder capacity was about 30 cc before the operation. Following the cystoplasty, it increased up to 180-220 cc by the 50th postoperative day, and the frequency of urination was 8 times in day and 3 times in night.

Forty five patients with inferior vena cava (IVC) thrombosis were studied with the use of ultrasonography (US) and computed tomography (CT). Thirty seven cases were cased by tumor extension and the primary neoplasms were hepatocellular Ca. (26cases), renal cell Ca. (6 cases), Wilms' tumor (1 case), IVC leiomyosarcoma (1 case) and retroperitoneal metastatic tumor (3 cases). Non-tumor thrombus were 8 cases which included 5 cases of Budd-Chiari syndrome and 3 cases of thrombophlebitis. US and CT both were good for the diagnosis of IVC thrombosis. Cranial extension was better demonstrated by US whereas CT yielded better delineation of the lower extension. Even though, differentiation of tumor non-tumor thrombi by the echogenecity and density of the thrombus was not possible, the finkdings of adjacent tumor mass, complete obstructive thrombus within dilated lumen with bulging wall, and nontapered acute margin of thrombus made the possibility of tumor thrombus more likely.

PURPOSE: To determine whether subtraction images utilizing contrast media can improve the diagnostic performance of proximal caries diagnosis compared to conventional periapical radiographic images. MATERIALS AND METHODS: Thirty-six teeth with 57 proximal surfaces were radiographied using a size #2 RVG-ui sensor (Trophy Radiology, Marne-la-Vallee, France). The teeth immersed in water-soluble contrast media and subtraction images were taken. Each tooth was then sectioned for histologic examination. The digital radiographic images and subtraction images were examined and interpreted by three dentists for proximal caries. The results of the proximal caries diagnosis were then verified with the results of the histologic examination. RESULTS: The proximal caries sensitivity using digital subtraction radiography was significantly higher than simply examining a single digital radiograph. The sensitivity of the proximal dentinal carious lesion when analyzed with the subtraction radiograph and the radiograph together was higher than with the subtraction radiograph or the radiograph alone. CONCLUSION: The use of subtraction radiography with contrast media may be useful for detecting proximal dentinal carious lesions.
