Infestation of Digenetic Trematode Cercariae from Semisulcospira Snails in Stream Odong

SUH, Chang Sik,MOON, Chu Hwan,KONG, Hyun Hee,CHOI, Dong Wik 慶北大學校 醫科大學 1993 慶北醫大誌 Vol.34 No.1

1991年 6月부터 同年 10月까지 慶北 達城郡 梧洞에서 다슬기를 採集하여 吸蟲類 有尾幼蟲의 寄生狀을 調査하였다. 다슬기에서의 有尾幼蟲의 寄生率은 26%였으며, 3種의 吸蟲類 有尾幼蟲 즉, Centrocestus armatus(Tanabe, 1922) Yamaguti, 1933, Metagonimus species 및 Notocolylus magniovatus, Yamaguti, 1934를 찾아볼 수 있었다. 이 가운데서 Metagonimus species 有尾幼蟲은 가장 많이 遊出되었고, 그 다음은 C. armatus, N. magniovatus의 順位로 遊出되었다. 이번 調査 結果 3種의 吸蟲類 有尾幼蟲의 寄生率은 1980年 보다 多少 增加되었으나, 肺吸蟲 有尾幼蟲은 發見할 수 없었다. 따라서 過去, 肺吸蟲 浸潤地였던 梧洞은 肺吸蟲의 浸潤地가 아님을 알았다. From June to October in 1991, Semisulcospira snails collected in the stream Odong, in Kachang Myon, Dalsong county, Kyungpook Province were examined for the presence of cercariae of digenetic trematodes. The infestation rate for cercariae in 2,437 snails was 26%. Three kinds of cercariae, Centrocestus armatus(Tanabe, 1922), Yamaguti, 1933, Metagonimus species, and Notocotylus magniovatus, Yamaguti, 1934, were found. However, no Paragonimus westermani cercariae was found. The most frequently found cercariae was Metagonimus species 23.5%, followed by C. armalus 2.3%, and the least frequently was N. magniovatus 0.2%. The low density of Semisulcospira snails and no P. westermani cercaria indicate that the stream Odong is no longer an endemic focus of P. westermani.

존속된 복강임신 1 례

정난주,서창식,황의수,강선영 대한산부인과학회 1997 Obstetrics & Gynecology Science Vol.40 No.3

Intra-abdominal pregnancy is uncommon occurrence, constituting only 1% of all ectopic pregnancy. It is usually the result of a tubal or ovarian pregnancy that has aborted or ruptured into the peritoneal cavity. However, the complications of abdominal pregnancy can be devastating. Premature placental separation with massive hemorrhage, hypofibrinogenemia following fetal demise, and suppuration and abscess formation lead to producing maternal health risk. A perinatal mortality and maternal mortality were 85-95% and 0.5-6% respect-ively, from the world literature. Optimal obstetrical care requires early diagnosis and prompt surgical intervention. Recently, a patient presented to the St.Francisco general Hospital with a retained abdominal pregnancy of 6 years duration without complications, as discussed below.

20 주까지 진행된 파열성 자궁각임신 1 례

신승주,이문희,김혜숙,김순희,서창식 대한산부인과학회 1994 Obstetrics & Gynecology Science Vol.37 No.1

자궁각임신은 매우 드물고 해부학적인 특이성으로 인하여 파열전 조기진단이 중요함에도 불구하고 그것이 매우 어려운 것으로 알려져 왔다. 최근, 초음파의 발전으로 초음파를 이용한 자궁각임신의 조기 진단에 많은 심혈을 기울이고 있다. 본 저자들은 임신 20주까지 진행된, 파열성 자궁각임신 1례를 경험하였기에 문헌적 고찰과 함께 이를 보고하는 바이다. Cornual (Interstitial) pregnancy is a relatively uncommon but potentially catastrophic from of ectopic pregnancy, defined as implantation in the intramural portion of a fallopian tube. Its incidence is estimated to be between 2-4% of all tubal pregnancy. Because the greater distensibility and vascularity of this site lead to rupture at a latter gestational age and rapid intraperitoneal hemorrhage, interstitial pregnancy casues serious maternal mortality and morbidity. Although the diagnosis of this condition prior to rupture is difficult, early detection is essential to avoid a fatal outcome. We experienced a case of ruptured cornual pregnancy at 20 week gestation and so we present it with brief review of literature.

산전 초음파로 진단된 양측성 중복요관 및 요관류 1 예

이문희,김혜숙,김순희,서창식,황의수,이광우 대한산부인과학회 1994 Obstetrics & Gynecology Science Vol.37 No.9

중복요관은 흔한 선천성 요로계기형의 하나로서, 치료시기에 따라 예후가 현저하게 다르다. 태아신장의 초음파소견은 조기치료를 가능하게 하고, 비뇨기과 임상의들에게 다양한 수술방법을 선택할 수 있도록 하는데 매우 유용하다. 저자 등은 임신 32주에 산전 초음파로 진단된 양측성 중복요관 및 요관류 1예를 경험하였기에 문헌적 고찰과 함께 보고하는 바이다. Prenatal ultrasound represents an accurqate and reliable mothed for the detection of intrauterine anmalies. Despite numerous sonographic reports describling fetal renal abnormalities, there has been little mention of the abstructed duplex anomalies. Particularly ureterocele, whether associated or not with duplication of the collecting system, can be greatly affected by an early intrauterine diagnosis: Prenatal ultrasonographic diagnosis allows a good diagnostic and therapeutic assessment of the patients prior to serious impairment of renal function due to recurrent urinary tract infections with pyelonephritis, so that in most cases the urological surgeion can opt for a parechymal conserving procedure. The authors have experienced a case of bilateral duplex ureter with ureteroceles diagnosed at 32 weeks of pregnancy and report our experience with a brief review of literature.

적혈구제제용 백혈구제거필터 RF300의 성능평가

권소영,조남선,송순녀,이주연,임아현,이현미,지영천,서창식,박윤희 대한수혈학회 2012 大韓輸血學會誌 Vol.23 No.1

Background:Use of universal leukoreduction for prevention of leukocyte associated transfusion reactions is common practice in many countries. This study was conducted in order to evaluate the performance of a newly developed leukoreduction filter for red blood cells (RBCs), the RF300 (Kolon Industries, Inc, Gumi, Korea). Methods:Filtration time, RBC recovery, residual leukocyte count, and leukocyte removal rate were evaluated. To assess the quality of RBCs after filtration, percent hemolysis was monitored for a period of 21 days. Performance of the RF300 (N=78) was compared with that of the Bio-R O2 plus (Fresenius, Hamburg, Germany), the Pall Purecell RC (Pall Co., Washington, USA), and the Sepacell R-500N (Asahi, Tokyo, Japan). Results:The shortest filtration time was observed using the RF300 (P<0.05). Using the RF300, recovery of RBC was 96.5%, which was higher than that of two filters (P<0.05). Mean residual leukocyte count was 0.26×106/unit, with a leukocyte removal rate of 3 log. Using the RF300, mean percent hemolysis was 0.32% at day 21, which was comparable with that of two filters, but lower than that of one filter (P<0.05). Conclusion:The RF300 meets all established quality requirements for conduct of safe and effective leukoreduction of RBCs.

N/A Objective : To identify the causes of primary amenorrhea in the Korean population. Methods : We reviewed the available medical records of the 100 patients who had visited the Department of Obstetrics and Gynecology at Seoul National University Hospital with the complaint of primary amenorrhea and examined their karyotypes between January 1989 and December 2000. Review of history, physical examination, laboratory findings, imaging studies, and operative findings was done, when needed. Results : The mean age at diagnosis was 25.1±6.1 (mean±S.D.) years of age, ranged 14 to 40. Mllerian agenesis was the most common cause (40.0%), followed by primary ovarian failure (33.0%), and then followed by hypothalamic-pituitary failure (12.0%). Androgen insensitivity syndrome and Swyer syndrome were found in four patients (4.0%), respectively. Conclusion : This study shows that the common cases of primary amenorrhea in Korean women are Mllerian agenesis, primary ovarian failure and hypothalamic-pituitary failure.
