Of 43 scoliotic patients treated by Harrington instrumentation and posterior spinal fusion, 38 patients were taken of preoperstive correction by Risser localizer cast, turn buckle cast. Cotrel traction or halofemoral traction from April 1969 to June 1978 at the Department of Orthopaedic Surgery, Seoul National University Hospital. The correctaibility of scoliosis by preoperative correction were evaluated with its methods, etiology, age, severity of the curve and curve pattern. and following results were obtained: 1. Age distribution was from 8 years to 39 yeara of age and mean age was 17. 2 years. 2. The etiology of the 43 cases was idiopathic in 15 (34.9%), paralytic in 10(23.3%). congenital in 9 (20.9%), neurofibromatosis in 5(11.6%) and others in 4, 3. The most common curve pattern was thoracic curve in 20 cases (40. 8%), and thoraco-lumber curve in 13, lumbar curve in 9, double curve in 5. 4. The average initial curve was 80.7 degrees with the flexibility of 36.9% on side bending; preoperative correction 31.3 degrees (38.3%) and immediate postoperative correction 40.6 degrees (50.3%). 5. As preoperative correction, Risser localizer cast was applied in 23 cases (53.5%) with 28.8 degrees (37.4%) of correction, turn buckle cast in 1 case with 80. 0 degrees (54.1%) Cotrel traction in 5 case with 27.5 degrees (40.7%) and halofemoral traction in 9 cases with 36.9 degrees (38.2%). 6. The best correction was obtained in idiopathic type and then followed with paralytic and congenital type. 7. Halofemoral traction was effectively applied in cases of rigidand severe, curve, mostly in older patients; the initial curve 96.5 degrees with 28.5% of flexibility. 8. The best correction was obtained in thoracic curve (39%) and then followed with thoracolumbar and lumbar curve. Halofemoral traction was effectively applied in tho racic curve. 9. Duration of preoperative correction was 5.1 days in Risser localizer cast, 7 days in turn buckle cast, 6.4 days in Cotrel traction and 13.3 days in halofemoral traction. 10. Most of preoperative correction were obtained in a few days of traction; 92% in half week with Cotrel traction and 83% in half week and 91% in one week with halofemoral traction.

Basaloid-squamous carcinoma of the esophagus is rare and similiar to the solid type of adenoid cystic carcinoma of the salivary gland. The origin of this tumor is unknown. The tumor was located in the lower third of the esophagus. The case of basaloid-squamous carcinoma consisted of submucosal tumor showing carcinoma with a basaloid pattern and focal squamous differentiation associated with squamous cell carcinoma or carcinoma in situ of the esophageal mucosa. A few submucosal tumor cells were positive for cytokeratin.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

OBJECTIVE: We examined the vasoconstricting poperties of endothelin (ET) on isolated arteries from pregnant as well as non-pregnant uterus. METHODS: Arteries of the uterus were obtained from both hysterectomized uterus and during pregnany hysterectomy for control group and cesarean section for pregnant group. Rings of uterine artery were suspended on muscle chambers at their optimal length for generating tension and contractile properties were examined. RESULTS: ET-1 and ET-2 induced concentration-dependent constriction of both isolated arterial strips from non-pregnant and pregnant uterus. The contraction to ET-1 and ET-2 were more enhanced in full-term pregnancy. Furthermore, in pregnant group, sarafotoxin S6c and IRL 1620, ET. agonists, induced a dose-dependent contraction, which was not shown in those from non-pregnant human. Pretreatment of human uterine arterial strips from pregnant uterus with BQ610, an ET. antagonist, for 10 min resulted in a dose-related rightward shift of ET-1 response curve with diminution of maximal response. Schild plot analysis yielded a pA value of 7.29 with a slope of 0.98. However, BQ788, an ET antagonist, did not produce any rightward shift. The contraction to lower concentration (10-8~3*10-7 M) of sarafotoxin S6c was not affected by BQ788, whereas that to higher concentration (10-s-8*10-7 M) was marked diminished. However, BQ610 did not exnt any efFect on sarafotoxin S6c-induced contraction in arterial staips from pregnant uterus. When the bath solution was replaced with Ca-free physiological salt solution (PSS) containing 1 mM EGTA for 10 min prior to adding sarafotoxin S6c, sarafotoxin S6c-induced contraction was completely abolished. Sarafotoxin S6c (10 nM)-induced contraction was prefetentially blocked by a protein kinase C antagonist, H-7, whereas it was less sensitive to a calmodulin antagonist, calmidazolium, CONCLUSION: Based on above results, we concluded that ET plays an important role in regulating uterine blood flow through the activation of ETa and ETB receptors. Furthermote, ETB receptors may predominantly contribute to the modulation of human uterine circulation in full-term pregnancy.
