The clinicopathological study was performed on 80 patients with urinary bladder tumor between 1973 and 1983. The histopathological survey was carried out using preserved tumor specimen slide on the retrospective fashion, that included the growth pattern and vessel invasion. The results were as follows : 1. The tumor histology were papillary and nonpapillary in 70 %, and 30 %, respectively in growth pattern and 74 transitional cell carcinoma(TCC), 3 squamous cell carcinoma(SCC), 2 adenocarcinoma (AC) and 1 mucoepithermoid carcinoma in cell type. 2. The Fade of TCC, Go, G1. G2 and G3 were 1.4%, 36.5%, 39.2% and 22.9% respectively, and the stage of those, in which superficial tumors(pTis-pT1) and invasive tumors( pT2-pT4) were 57.0% and 30.8% respectively. The histopathological mode of local spread was to have strands, nests and individual cells in about one sixth, lymphatic invasion in about one third and venous invasion in about one fifth. 3. The intramural hispathological mode of local spread (INF alpha,beta, and alpha), lymphatic invasion ( lyo, 1 and 2) and venous invasion were highly significant with respect to the hispathological grade and stage, and also within mutual relationship on the other hand.

To determine the concentration and the physiologic role of metal components in blood plasma and seminal plasma in relation to male infertility, the concentrations of twelve metal components in blood plasma and seminal plasma including Na, Mg, K, Ca, Cr, Mn, Fe, Cu, Zn, Se, Cd and Pb were measured by atomic absorbance spectrophotometery or ion selective electrode analysis. Semen and blood samples were obtained from a total of 110 men including 70 male infertility patients, 20 vasectomized persons and 20 fertility proven volunteers visited to the Male Infertility Clinic of Pusan National University Hospital. The concentrations of Ca, Zn, Mg, Cr and Cd in control group were higher in seminal plasma than in blood plasma, and additionally Pb were higher in infertility group. The concentrations of all metal components revealed no significant difference according to patients' age, resident, occupation, sperm density, motility and hormone level in blood plasma, but some metal components including Ca, Mg, Cu, Mn, Cd and Pb revealed a significant difference according to each these parameters except patient's age in seminal plasma. The concentrations of Mn, Cd and Pb in the vasectomy persons were higher than in the infertility group III including testicular and epididymal factors, but not in blood plasma. We conclude that the quantitative changes of metal components in the seminal plasma may have effects on not only spermatogenesis and sperm function, but also contribute to diagnostic parameter according to organ specificity of the metal in the male reproduction.

Female pseudohermaphrodities are 46XX genetic females with normal Mullerian derivatives, but have various degrees of ambiguous external genitalia. While most of them are commonly associated with adrenogenital syndrome, some of them have been occasionally associated with maternal ingestion of testosterone or synthetic progestational agent, maternal virilizing tumor or rarely idiopathic. Herein, we present three cases of female pseudohermaphroditism which is unrelated with adrenogenital syndrome. One case is resulted from maternal ingestion of progestational agent during the first trimester of pregnancy, and the other idiopathic.

We studied the usefulness of prostate specific antigen (PSA) as well as prostatic acid phosphatase (PAP) as marker of prostatic cancer in twelve cases of advanced prostatic cancer including 4 or stage C and 8 of stage D, 50 cases of benign prostatic hyperplasia (BPH) and 50 cases of nonprostatic diseases as normal control. The positive rates of PSA were 100% for prostatic cancer, 20% for BPH and O% for nonprostatic diseases, and those of PAP were 75% for prostate cancer, 8% for BPH and 2% for nonprostatic diseases. These results indicated hat PSA is more sensitive than PAP but less specific than PAP in diagnosis of prostatic cancer. Serum PSP level was correlated with the weight of prostate in BPH patients. Serum PSA level determined during the follow-up after endocrine therapy for prostatic cancer reflected the clinical course of the patients. Because of its relatively low specificity, PSA alone may not be useful for early diagnosis of prostatic cancer. If in combination with other diagnostic modalities, it may be useful in early diagnosis and therapeutic monitoring of prostatic cancer within restricted limits.

Retroperitoneal teratoma are comparatively rare and yet difficult to treat and predict the prognosis. A case of primary retroperitoneal teratoma in a 28-year-old woman is presented, which was suspected by excretory urography, ultrasonography and angiography, and then preoperatively diagnosed by computerized tomography.

A group of the 59 patients (64 kidneys) of renal calculi, operated at our hospital in the past a half and four years from 1976 Jun. to 1980 May, was investigated statistically. 1. In the 64 operations there were 2 nephrectomies (3.1per cent), 12 pyelolithotomies (18.8 percent), 4 nephrolithotomies (6.3 per cent), 16 extended pyelolithotomies (25.0 per cent), 19 extended pyelolithotomies combined with local nephrolithotomies (29.7 per cent), 5 partial nephrectomies (7.8 per cent), and 6 lower pole pyelocalycotomies (9.4 per cent). From our experience the choice of surgery staghorn or multiple stone was indicated lower surgery is the treatment of choice most of the patients and nephrectomy was performed only in a small group. 2. In 62 conservative operations for renal calculi, residual calculi were observed in 6 kidneys (9.7 per cent). 3. In postoperative course, hematuria was discontinued within 3 days. Urine leakage also disappeared within 3 days in pyelolithotomy with closure of renal pelvis, but within 5 days in extended pyelolithotomy without closure of renal pelvis. In some cases, postoperative urinary tract infection was perpetuated by residual stone and preoperative infection.

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.
