If manometric profiles of sphincter of Oddi(SO) measured from the pancreatic duct and the bild duct are essentially equal, then measurement of manometric profiles from only one duct would be adequate in evaluating SO dysfunction. We report a series of 9 patients whom we evaluate with SO manometry. Cannulation of both the biliary sphincter segment and pancreatic sphincter segment was archived consecutively in one session and we compared the manometric parameters of choledochal sphincter from those of pancreatic sphincter. 1) In 7 out of 9 patients(78%), normal manometric finding of SO were seen in both choledochal and pancreatic sphincters. However, in 2 out of 9 cases(22% ) abnormal manometric findings were noted in only one sphincter segment. Elevation of basal pressure(n = l ) and increased retrograde propagation(n = 1) were found in the pancreatic sphincter segment alone. 2) Tbe mean intraductal pressure in the pancreatic duct was significantly greater(12.6+-5.8mmHg) than that of common bile duct(3.8+-3.3mmHg)(p$lt;0.01). However, basal pressure, amplitude, frequency and propagation sequence in the phasic contraction of SO were not different significantly between choledochal and pancreatic sphincter segment. In conclusion, SO manometry of both the pancreatic and bile duct is needed if complete manometric information is desired. Selective cannulation of common bile duct and pancreatic duct during SO manometry is necessary in order to diagnose segmental 50 dysfunction.

We evaluated the clinical characteristics of patients with SO dyskinesia(n=16) who were confirmed by ERCP manometry during past 5 years. They were 14 male and 2 female and mean age was 52-year-old(range, 32-75). According to the criteria suggested by Hogan and Geenen, 13 patients were classified into biliary type and 3 patients into pancreatic type. Among the patients with biliary type(n=13), 12 patients fulfilled the criteria for group II dysfunction of SO and 1 patient for group III. Among the patients with pancreatic type(n=3), all fulfilled the criteria for group II. The manometric abnormalities were increased basal pressure(n=4), tachyoddia(n=7), increased retrograde propagation(n=3), tachyoddia and increased retrograde propagation(n=l), and tachyoddia and increased basal pressure(n=l). As treatment, 12 patients received conventional endoscopic sphincterotomy and 3 patients received endoscopic pancreatic sphincterotomy in addition to conventional endoscopic sphincterotomy. Satisfactory results (complete absence or marked reduction of pain) were obtained in 13(87%) out of 15 patients by endoscopic treatment. In conclusion, SO dyskinesia is not so common disease and the detection of patients with SO dyskinesia may increase by frequent application of ERCP manometry.

Erythropoietin 투여중인 만성 신부전 환자에서 발병한 급성 골수성 백혈병 1예
박수현,김현태,구자룡,채동완,김근호,박규용,노정우,이준상,여미애,김형직,전로원,권성희 대한내과학회 2000 대한내과학회지 Vol.59 No.6
Recombinant human erythropoietin is a synthetic glycoprotein hormone and has the effect on bone marrow erythroid progenitor cells. Therefore, recombinant human erythropoietin has been frequently used as an agent treating anemia in chronic renal failure patients. However, Stockenhuber reported that recombinant human erythropoietin also affected other bone marrow progenitor cells (colony- forming unit-granulocyte-erythrocyte-macrophage, colony-forming-gra-nulocyte-macrophage). This reports may suggest a possible casual relationship between acute myeloid leukemia and erythropoietin. Acute myeloid leukemia is a rare disease in patients with chronic renal failure especially on erythropoietin treatment. By this time only a case of acute leukemia in chronic renal failure was reported by Campistrus in 1995. Campistrus's case was on the remission state of acute myeloid leukemia, and erythropoietin was administered to treat anemia of chronic renal failure. Also no previous case of acute myeloid leukemia developed in chronic renal failure patients on erythropoietin treatment was yet reported in Korea. So, we report a case of acute myeloid leukemia developed in a pre-dialysis chronic renal failure patient but on erythropoietin treatment.(Korean J Med 59:674-678, 2000)

Extended Benefit-Cost Analysis of Irrigation and Drainage Project

농업부문이 사회에 제공하는 다양한 긍정적 외부효과가 인정됨에 따라, 대부분의 농업생산기반시설은 국부를 증진시키는 사회간접자본으로 인식되고 있다. 과거에는 수리시설을 비롯한 기반시설이 단지 생산성 향상을 위한 사회적 투자로 간주되었으며 따라서 사업에 대한 경제성 분석 또한 직접적인 경제적 효과에 대한 편익비용분석에 국한되었다. 그러나 최근에는 농업 및 생산기반시설이 제공하는 비시장적 가치가 점차 인정됨에 따라 그러한 가치 또한 경제성분석에 포함될 수 있다
