Hepatocellular carcinoma(HCC)is one of common causes of cancer-related death in Korea where the majority of HCC patients were Hepaitc B virus(HBV)carriers and have cirrhosis. Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.

Prediction of retained austenite fraction is quite important in designing advanced high strength steels since retained austeniteis the source of transformation-induced plasticity. The present study investigates the phase constitution of a medium-carbonQ&P steel by comparing various approaches to the transformation stasis of bainitic ferrite and applying them to the partitioningprocess. Among them, the modified GEB approach gave the best agreement with the experimental observation, includingthe effects of heat-treatment condition and chemical composition on phase constitution. This indicates phase transformationduring partitioning can be effectively described by the physics of Gibbs energy balance approach.

위암은 국내에서 발생 빈도가 가장 높은 암으로서 근치적 절제술 및 확대 영역 림프절 절제술의 도입과 더불어 술후 보조 항암화학요법 및 면역요법 등의 이용으로 최근 치료성적의 향상을 보이고 있다. 그러나 수술적 치료를 포함한 치료법의 발전에도 불구하고 다양한 형태의 재발을 경험하게 되고, 대부분의 재발은 3년 이내에 일어난다. 재발양상으로는 크게 국소재발, 원격재발, 복막재발 등이 있으며, 여러 가지 재발양상이 한꺼번에 보이는 경우도 있다. 이 중 국소재발의 호발 부위로는 림프절($48\%$), 문합부($32\%$, 잔존 위($20\%$)의 순으로 보고되고 있다. 증례: 51세의 여자 환자로 1999년 10월 진행성 위암으로 근치적 위전절제술을 시행 받았고, 당시 병기는 T3N1M0(IIIa,AJCC 1997)이었다. 수술 후 10회의 보조적 정맥 주사용 항암화학요법 및 경구용 항암화학요법을 2년간 실시하였고, 외래를 통한 추적검사상 약 5년간 재발을 보이지 않았으나 2004년 9월 시행한 내시경상 Kim's tie 부근공장에서 궤양성 병변을 발견하고 조직검사를 시행, 병리학적으로 낮은 분화도를 보이는 인환 세포암종 형태의 위선암 재발로 진단하고 수술을 시행하였다. 수술 방법은 Kim's tie 위치를 포함해 근위부 6.5 cm, 원위부 4 cm의 절제연을 두고 공장부분 절제술을 시행하였다. 수술 당시 다른 복부장기로 전이는 없었으며 전이성 복수도 없었다. 수술 후 별다른 합병증 없이 회복하였으며 보조 항암화학요법 제제로써 TS-1을 사용하며 외래 통한 추적검사 중이다. Despite improvements in the surgical treatment of gastric adenocarcinomas, the recurrence rates remain high in patients with advanced-stage disease. Most of the recurrence occurs within 3 years of the surgical resection, and nearly $90\%$ of the patients with recurrence die within 2 years of the diagnosis of recurrence. A recent study analyzed recurrence patterns for patients who had undergone a potentially curative gastrectomy. For those patients, $33\%$ of the recurrences involved locoregional sites, $44\%$ the peritoneum, and $38\%$ distant sites. A 51-year-old female patient was diagnosed with stomach cancer and underwent a total gastrectomy with D2 lymph node dissection during Oct. 1999. The pathologic report indicated a T3N1M0 tumor. We performed immunochemotherapy for 2 years with regular follow up. A gastrofiberscopic examination done during sep. 2004, cancer recurrence was found at the Kim's tie site of the jejunual loop. We did an abdominal exploration and a segmental resection of cancer site with pathologically negative resection margins. After the operation, we started secondary chemotherapy with TS-1.

Byung-Chan Koo,Jeong-Soo Kim,Hyun-Ho Kwak,In-Ryoung Kim,Seung-Eun Lee,Gyoo-Cheon Kim,Hongsuk Suh1,Bong-Soo Park 대한해부학회 2009 Anatomy & Cell Biology Vol.42 No.1

Bile acids and synthetic bile acid derivatives induced apoptosis in various kinds of cancer cells and anticancer effects. Although synthetic chenodeoxycholic acid (CDCA) derivatives have been demonstrated to induce apoptosis of various cancer cells, there is no report on their effect on RBL-2H3 basophilic leukemia cell line to date. Therefore, this study was undertaken to examine in vitro effects of cytotoxicity and growth inhibition, and the molecular mechanism underlying induction of apoptosis in RBL-2H3 cells treated with a synthetic CDCA derivative, HS-1200. The viability and the growth inhibition of RBL-2H3 cells were assessed by MTT assay and clonogenic assay respectively. The Hoechst staining and DNA electrophoresis were conducted to observe RBL-2H3 cells undergoing apoptosis. RBL-2H3 cells were treated with HS-1200, and Western blotting, immunocytochemistry, confocal microscopy, DNA hypoploidy assay, MMP activity and proteasome activity were performed. HS-1200 treatment of RBL-2H3 cells resulted in a time- and does-dependent decrease of cell viability and a does-dependent inhibition of cell growth, and induced apoptotic cell death. Furthermore, HS-1200 treatment result in the alteration of G1 cell cycle-related proteins. And tested RBL-2H3 cells showed several lines of apoptotic manifestation.We presented data indicating that HS-1200 induces apoptois via the proteasome, mitochondria and caspase pathway, and induces the alteration of the G1 cell cycle-related proteins in RBL-2H3 cells. Therefore our data provide the possibility that HS-1200 could be as a novel therapeutic strategy in the allergy treatment.

Background/Aims: The most commonly used immunosuppressant therapy after liver transplantation (LT) is a combination of tacrolimus and steroid. Basiliximab induction has recently been introduced; however, the most appropriate immunosuppression for hepatocellular carcinoma (HCC) patients after LT is still debated. Methods: Ninety-three LT recipients with HCC who took tacrolimus and steroids as major immunosuppressants were included. Induction with basiliximab was implemented in 43 patients (46.2%). Mycophenolate mofetil (MMF) was added to reduce the tacrolimus dosage (n=28, 30.1%). The 1-year tacrolimus exposure level was 7.2 ± 1.3 ng/mL (mean ± SD). Results: The 1- and 3-year recurrence rates of HCC were 12.9% and 19.4%, respectively. Tacrolimus exposure, cumulative steroid dosages, and MMF dosages had no impact on HCC recurrence. Induction therapy with basiliximab, high alpha fetoprotein (AFP; >400 ng/mL) and protein induced by vitamin K absence/antagonist-II (PIVKA-II; >100 mAU/mL) levels, and microvascular invasion were significant risk factors for 1-year recurrence (P<0.05). High AFP and PIVKA-II levels, and positive 18fluoro-2-deoxy-d-glucose positron-emission tomography findings were significantly associated with 3-year recurrence (P<0.05). Conclusions: Induction therapy with basiliximab, a strong immunosuppressant, may have a negative impact with respect to early HCC recurrence (i.e., within 1 year) in high-risk patients.

Convulsive disorder is the most part of the pediatric neurologic disease. As far as the treatment of convulsive disorder concerned, we must consider familys' understanding, and the close cooperation between the epileptic child, parents, and doctors. We compared to Kim's report in 1985, to study the change of parents of epileptic children thinking. A prospective study was undertaken the analysis of 100 epileptic children parents visited to the pediatric dept, of Soonchunhyang university hospital from May to July, 1995. Psychological assessment, questionnaires which contains 17 items were given them, and these items were compared to Kims report in 1985 The results were as follows: 1) Parents of epileptic children answered convulsive disorder has influenced to children growth and development( 60.8% in 1985, 65.0% in 1995 ). 2) For asking the causes of children disease, 40.5% of them in 1985 and 50.0% of them in 1995 answered to uncertain, but only 7.8% of them in 1985 and 7.0% of them in 1995 answered to relation with familial inheritance. 3) The feelings at time of the diagnosis were gloomy or uncomfortable: 52.3% in 1985, 38.0% in 1995 and shameful 28.1% in 1985, 9.0% 1995. parents had belived in the epilepsy was treatable disease: 41.0% in 1995. 4) According to the this survey, patients explained reasons why their children take the medication increased from 23.5% in 1985 to 65.0% in 1995. 5) Only family, knew that their children had the convulsive disorder about 50.3% in 1995 and 22.0% in 1995. Family, patients and other people except family knew that their children had the convulsive disorder about 6.5% in 1985 and 43.0% in 1995. 6) The parents opinion and expectation toward the medical doctors were that they wanted to get full explanation for the disease 81.0% in 1985 and 35.1% in 1995, and others were explantation about toxicity and side effects of the medication and advises for the childrens life and activities.

The aim of this study was to investigate urinary metabolomics profiles associated with cadmium (Cd)-induced nephrotoxicity and their potential mechanisms. Metabolomic profiles were measured by high-resolution 1H-nuclear magnetic resonance (NMR) spectroscopy in the urine of rats after oral exposure to CdCl2 (1, 5, or 25 mg/kg) for 6 wk. The spectral data were further analyzed by a multivariate analysis to identify specific urinary metabolites. Urinary excretion levels of protein biomarkers were also measured and CdCl2 accumulated dose-dependently in the kidney. High-dose (25 mg/kg) CdCl2 exposure significantly increased serum blood urea nitrogen (BUN), but serum creatinine (sCr) levels were unchanged. High-dose CdCl2 (25 mg/kg) exposure also significantly elevated protein-based urinary biomarkers including osteopontin, monocyte chemoattractant protein-1 (MCP-1), kidney injury molecules-1 (Kim-1), and selenium-bingding protein 1 (SBP1) in rat urine. Under these conditions, six urinary metabolites (citarate, serine, 3-hydroxyisovalerate, 4-hydroxyphentllactate, dimethylamine, and betaine) were involved in mitochondrial energy metabolism. In addition, a few number of amino acids such as glycine, glutamate, tyrosine, proline, or phentlalanine and carbohydrate (glucose) were altered in urine afrer CdCl2 exposure. In particular, the metabolites involved in the glutathione biosynthesis pathway, including cysteine, serine, methionine, and glutamate, were markedly decreased compared to the control. Thus, these metabolites are potential biomarkers for detection of Cd-induced nephrotoxicity. Our results further indicate that redox metabolomics pathways may be associated with Cd-mediated chronic kidney injury. These findings provide a biochemical pathway for better understanding of cellulat mechanism underlying Cd-induced renal injury in hunmans.

Initial yield conditions and elastic-plastic response of sintered porous iron are investigated under combined tension and torsion. By using tubular specimens of initial relative densities 0.8 - 0.9, initial yield conditions were compared with several yield functions in the literature. Kim's yield function agreed well with experimental data from combined tension and torsion of sintered porous iron. Gurson's and Richmond and Smelser's yield functions did not agree well with data for initial densities lower than 0.9. Shima and Oyane's yield function showed reasonably good agreement in tension, but not so good in torsion. Other characteristic behaviors of porous metals are also investigated.
