The nutcracker syndrome refers to the compression of the left renal vein between aorta and superior mesenteric artery which results in hematuria, at times associated with flank pain, abdominal pain or varicocele. We report a girl with this syndrome presenting with persistent gross hematuria for 2 months. Urine erythrocytes showed only 1% of dysmorphism, and ultrasonography revealed compression of left renal vein between arota and superior mesenteric artery, and left sided unilateral bleeding was confirmed by cystoscopy. Intraarterial digital subtraction angiography revealed compression of left renal vein and collateral circulation to left gonadal vein. The pullback pressure tracing from left renal vein to inferior vena cava showed pressure gradient of 3 mmHg between left renal vein and inferior vena cava. Ultrasonography and intraarterial digital subtraction angiography revealed the compression of the left renal vein between the aorta and superior mesenteric artery and regurgitation of the gonadal vein. The nutcracker syndrome should be considered as one of the causes of nonglomerular hematuria.
요추 불안정증에 대한 전측방 및 후방경유 추골체 융합술의 비교 검토

Interbody fusion was performed on eight, cases of lumbar instability; five spondylolisthesis and three spondylolysis. Five cases were operated by anterolateral approach through the retroperitoneal space, and posterior approach on three cases after Cloward. Symptomatic improvement was obtained in almost all cases and complete fusion was observed on the roentgenogram three months later. Ambulation was possible from the immediate postoperative day without external support. While posterior approach has an advantage to observe the nerve root under direct vision, anterolateral approach has the following advantages; It is less destructive to the spinal structures. It can be performed without teasing the neural elements, anterior slipping of the vertebral body can be reduced easily, and it was applicable to the upper lumbr level where neural elements are compact. We believe interbody fusion has definite advantage to obtain strong weight bearing stability than fusion of any other parts of the spine because it has rapid recovery, low morbidity and high percentage of complete cure without disability.
自然科 天文·氣象敎材의 槪念體系와 內容構成에 關한 硏究 : 季節의 變化 單元을 中心으로 Especially in the Change of Seasons Unit
金光明 춘천교육대학교 과학교육연구소 1983 과학교육연구 Vol.10 No.-
The Change of Seasons Unit have developed lately in new science curriculum of elementary school. In this study, the conceptional schemes and contents of the Change of Seasons unit were compared to old one and those of foreign country. There appears some improperness and unsuitability in the Change of Seasons unit which are: 1. There are little learning materials which may help to study the general weather picture during the period of seasonal change, 2. In this Unit, anything about different forms and amounts of precipitation will be studied, 3. There appears little subjects about unusual kind of weather we have in Korea which is typical to seasons.

A chromosomal study was performed in a total of 162 urological patients during past 2$2{\frac{1}{2}}$ years (Feb. 1984 - Aug. 1986). Of these 78(48%) patients had abnormal chromosome complements. Among all patients with chromosome abnormalities, 88% (69/78) had aberrations of chromosome number, 8% (6/78) had aberrations of chromosome structure and 4% (3/78) had aberrations of both. 90% (65/72) of numerical abnormality was Klinefelter's syndrome and the structural abnormality rate (5.6%, 9/162) was less than that (6.99%) of general population. The chromosomal study was mandatory for the detection of intersex in small testes or hypospadias with cryptorchism or clitoromegaly or bilateral cryptorchism. But unilateral cryptochism or hypospadias with normal scrotal testes was not thought to be indication of the chromosomal study if the external genitalia are otherwise quite normal.
