A clinical observation was made on the obstruction at the ureteropelvic Juncture of the inpatient in the Department of Urology. Seoul National University Hospital during the period September, 1961 through August, 1968 and the following results were observed. 1. Of 1824 cases hospitalized, 33 cases werehydronephrosis of non-calculous origin. Among the 33 cages 10 were obstruction ofthe ureteropelvic juncture giving a rate of 30.3%. Age distribution ranged from 4to 48 years with average of 26 years. 2. As to the origin of the obstruction, 5 cases were due to aberrant vessel one congenital stricture one fibrous band and one fibrosis, respectively. The causes were unknown in 2 cases. 3. The most common complaints were pain on the involved site in 8 cases. Palpable mass, gastrointestinal trouble and general weakness were found in 6 cases. Loss of weight and pollakisuria were noted in 3 cases. Hypertension. hematuria, fever andedema were found respectively in one case. 4. All cases including two which showed non-function on IVP showed markedly dilated pelvis and marked narrowing ofthe ureteropelvic juncture. 5. Nephrectomy was performed in 5 cases, removal of aberrant vessel in 2, ureteroplasty in one and ureteral dilation with contralateral nephrectomy in 2.

Both fibronectin and vitronectin bind to Pneumocystis carinii (P. carinii) and mediate the attachment of the organisms to respiratory epithelial cells. Surfactant A and D play a role in the interaction between P. carinii and host cells. In this study we examined the expression of fibronectin, vitronectin, surfactant-A and D in the interaction between P. carinii and alveolar epithelial cells by immunohistochemistry and pre-embedding immunoelectron microscopy. The experimental rat model of P. carinii pneumonia was induced by administration of low protein diet (8%) and drinking water containing dexamethasone (2 mg/liter) for 6 to 8 weeks. The primary antibodies for light and electron microscopic immunohistochemistries were monoclonal antibodies including fibronectin (1:100) and vitronectin (1:100), and polyclonal antibodies including surfactant A (1:50) and D (1:50), respectively. Light microscopic immunohistochemistry for the fibronectin, vitronectin, surfactant-A and D showed strong expressions on the P. carinii and surface linings of type I alveolar epithelial cells. The electron microscopic immunohistochemistry of the fibronectin and vitronectin showed a strong immunoexpression along the surface pellicles and tubular extensions of P. carinii trophozoites, and surface membranes of the type I epithelial cells. The surfactant-A and D proteins showed a strong expression on the pellicles of P. carinii and surface membranes of the type I epithelial cells, but a weak expression on the free-floating surfactant materials. In conclusions, the trophozoites of P. carinii were mostly attached to type I epithelial cells. The fibronectin, vitronectin, surfactant-A and D were strongly expressed, and played an enhancing role in the binding between the P. carinii organisms and the type I alveolar epithelial cells.

The Enchondroma is a benign cartilage forming harmartoma arising chiefly from short tubular bones on hands and feet. If on a long tubular bone or flat bone such as femur or ilium, it is most likely to be a true neoplasm such as chondrosarcoma, not a harmartoma. A case of enchondroma was reported. It occurred over right ischium of 19 years old male and was found incidentally by roentgenogram. The lesion was biopsied and diagnos's was confirmed by histologic examination. It was treated by curretage with filling of cavity with bone chips. Post operative-course was uneventful.

Tibial Fractures*

The fibrous dysplasia, divided into 3 categories of the monostotic, polyostotic and extraskeletal forms, is a relatively rare disease which was first reported by Well in 1922 and shows a characteristic findings replacing the medullary cavity of noe or more bones by the pathologically proliferating fibrous connective tissues. In a consequence, the structural integrity of the diseased bone becomes weakened and suffers frequent episodes of pathologic fracture and deformities of the bone, which are most common around the hip. Various operative methods and instruments have been tried to manage the pathologic fracture around the hip recently. The authors report a satisfactory resnlt of total hip replacement for the pathologic fracture in a patient of the fibrous dysplasia involving the proximal half of the right femur.
