Meigs' syndrome is defined as presence of pleural effusion, with ovarian tumor associated ascites, which spontaneously resolve soon after the removal of the tumor. The pathogenesis of the pleural effusion, in patients with Meigs' syndrome, is thought to be the passage of fluid from the peritoneal cavity into the pleural cavity, through small holes in the diaphragm. A case of Meigs' syndrome, in a 63-year-old woman, who had been referred for control of pleural effusion is reported.

Hemophagocytic syndrome(HPS) has four subgroup, sporadic disorder, associated with acute infection, familial form seen in children, and associated with malignant disorders, immunodeficiencies, defective leukocyte function. Histologically, Hemopoietic cells are actively ingested by moncytes/macrophages in various organs, including lymph nodes, bone marrow, liver, and spleen. Epstein-Barr virus(EBV) is now thought to be one of the major causes for the virus-associated hemophagocytic syndrome(VAHS). Epstein-Barr(EB) virus infection is common, with up to 90% of individuals demonstrating positive titiers by age 20. Although elevated liver function tests commonly occur, severe hepatitis is rare. Only seven cases of ascites complicating Epstein-Barr infection are reported, but none clearly demonstrate the abscence of other causes of hepatic dysfunction. We are reporting a case of Epstein-Barr Virus-associated hemophagocytic syndrome with ascites.

Tuberculous peritonitis is a rare cause of intra-abdominal infection. Although sometimes asymptomatic, most of the patients have fever, weight loss, abdominal pain, and edema. The diagnosis of tuberculous peritonitis is difficult and sometimes delayed because of confusion of the disease with other illnesses and the non-specificity of signs and symptoms. Tuberculous peritonitis is examined with ultrasonography and computerized tomogram, but confirmed by biopsy or tuberculosis culture. Ascitic fluid is exudates with a lot of lymphocytes and elevated protein. Tuberculous peritonitis is treated successfully with isoniazid, rifampicin for one year, pyrazinamide for first 2 months and streptomycin for first one month. We experienced one case of tuberculous peritonitis with transudate of ascitic fluid, confirmed by biopsy using colonoscopy, and treated successfully.

DC Hollow cathode 방전은 약 100여 년 전, Paschen에 의해 실험된 이후로 광원, 스퍼터링 공정, 이온빔 소스 등 다양한 분야에 이용되어 왔다. 최근 태양전지용 마이크로 결정질 실리콘 증착 시, RF CCP의 전극에 복수의 홀 혹은 트렌치 구조를 두어 Hollow cathode 방전 효과를 이용하여 향상된 공정 속도로 공정을 진행한다. 그러나 RF-MHCD (Multi hole cathode discharge) 공정을 위한 최적 규격의 홀 기에 관한 연구는 그 중요성과 응용성에도 불구하고 깊게 이루어지지 못한 바 있다. 그러므로 저자는 Capacitively Coupled Plasma (전극 간격 : 4cm, 전극 직경 : 14cm) 장비에서 평면 전극과 10mm 깊이와 각각 3.5mm, 5mm, 7mm, 10mm 직경의 홀이 있는 4개의 전극을 이용하여 Argon RF-MHCD 방전을 관찰하여 조건 별 최적의 홀 전극 디자인을 도출하였다. 실험 조건은 64.5mTorr ~ 645mTorr압력 범위/ 1A~9A이며, 플라즈마는 전극 사이 중앙에 설치한 RF-compensated Langmuir Probe와, 전극과 전기적으로 접촉하는 1000:1 Probe 와 Voltage-Current Probe를 이용하여 측정되었다. 실험 결과 압력 조건 별로, 최적의 전자 밀도를 유도하는 전극 상 홀의 직경이 달라짐을 확인하였다.

Eosinophilic gastroenteritis is a rare disease occurring especially in children, and shows various nonspecific presentations with infiltration of eosinophils in the gastrointestinal organs. The pathophysiology of eosinophilic gastroenteritis is not yet clearly known, but allergic reactions are suspected to be related with the disease. Eosinophilic gastroenteritis is categorized into the mucosal, muscularis and subserosal types based on which layer of the intestinal wall is involved. There are different clinical manifestations according to the involved layer. Most cases to date have responded well to steroid therapy. In this study, we diagnosed and treated a case of non-IgE-mediated, subserosal eosinophilic gastroenteritis in a child with abdominal pain, diarrhea and ascites.

The authors have proposed novel TDD-CDMA systems with Pre-Rake transmit diversity schemes (system 1 and system 2) using multiple transmit antennas in [2] and have also evaluated the system performance through the theoretical analysis and computer simulation. However, the performance of system 2 which transmit a signal using all antennas has not been evaluated for multi-user environment. Therefore in this paper, we analyze the performance of system 2 for multi-user environment and compare the performance with that of the already proposed system 1 which chooses only one antenna. From the numerical results, it is found that system 2 outperforms system 1 as the number of users increases while system 1 outperforms system 2 at a small number of users. Therefore in order to achieve the best system performance, the Pre-Rake transmit diversity type should be selected at the base station according to the number of users.

Castleman's disease is a rare non-neoplastic lymphoproliferative disorder of unknown etiology. It is divided into three histologic subtypes; hyaline-vascular(HV), plasma cell(PC) type and mixed type (HV-PC). It has two clinical expressions. The localized form, which presents as a slow growing mass, has a relatively benign clinical course. The multicentric form is multilocated and holds significant morbidity. The mainstay of treatment of the localized form is surgical resection. The multicentric form requires medical treatment comprising prednisolone and other immunosuppressor drugs. The disease in children seems to have a more favorable course than in adults. We report a 13-year-old boy with Castleman's disease of multicentric form who was successfully treated with prednisolone and intravenous immunoglobulin.

Spontaneous perforation of the biliary duct is a rare disease that must be treated immediately when diagnosed in infancy. This disease must be suspected in a previously healthy infant who suddenly has abdominal distension, ascites, and intermittent jaundice. The best way to diagnose the leakage of bile in a clinically stable infant is to use radionuclide hepatobiliary scan. In most cases, however, the diagnosis of the perforation of common bile duct is frequently made during the procedure of operative cholangiogram. The prognosis is usually good with early diagnosis. We experienced an infant of 4 months of age who presented with sudden abdominal distension, jaundice and acholic stool, and confirmed the diagnosis of perforation of common bile duct through operative cholangiogram with t-tube insertion. We report a case of spontaneous perforation in an infant with review of the literatures.

Interleukin-2 (IL-2)는 많은 immunoenhancing lymphokine의 한 종류로서 lymphokine activiated killer (LAK) cell의 생성을 자극시켜 흑종의 종양세포를 죽인다고 알려져 있다. 최근 간종양에서 비장동맥 또는 간동맥으로 투여한 IL-2가 비장의 임파계를 자극하여 LAK cell을 생성하여 어느정도효과가 있음이 밝혀지면서, 여러가지의 투여 방법이 시도되고 있다. 그러나 각종의 투여 방법에서 실제로 투여한 IL-2의 인체내 분포에 관한 연구는 없다. 저자들은 비정맥과 간문맥에 이상이 없는 증례의 비동맥에 IL-2와 $^{99m}Tc-phytate$ 혼합물을 투여하고, IL-2의 생체에서의 비장과 간에 어떻게 분포하는지 알아보기 위하여 $^{99m}Tc$의 radioactivity를 계측하여 보았다. 6예의 간세포암과 3예의 위암으로부터의 전이성간암에서 동맥조영술적방법을 이용하여 초선택적 비장동맥에 투여한 IL-2와 $^{99m}Tc-phytate$ 혼합물이 비장 27%, 간73%의 분포를 보여 비장을 거쳐온 $^{99m}Tc$의 방사능이 간에 많이 침착함을 확인하였고 간과 비장이외의 부위 즉 골수, 복수 또는 폐장이나 늑막에는 전혀 방사능 분포가 없음을 알 수 있었다. 따라서 비정맥이나 간문백에 이상이 없는 증례에서 IL-2의 비장동맥 투여는 목적하는 바 IL-2의 생체내 분포를 이룩할 수 있을 것으로 사료된다.

Congenital syphilis is a rare cause of non-immune hydrops fetalis. We cared for a neonate with hydrops fetalis who was delivered by emergency Cesarean section due to prolonged fetal bradycardia and ascites at 34 weeks of gestation. He had anemia, purpura, and hepatosplenomegaly, and the serologic tests revealed congenital syphilis (high titers of serum VDRL and TPHA, and a positive serum FTA-ABS IgM). He survived after aspiration of ascitic fluid, ventilator care, and intravenous penicillin therapy. We report a case of non-immune hydrops fetalis due to congenital syphilis with a brief review of literature.
