The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

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.

Fungi belonging to the Paecilomyces spp. have recently been used as food and herbal medicines in Korea and are greatly popular as commercially available powdered supplement or dried fruiting body. Despite this acceptance and its use, little is known of the genes related to its reactive agents. Presently, We have constructed an olig-d(T) primed directional cDNA library from the silkworm Dongchunghacho, an entomopathogenic fungus, of which species is belonging to Paecilomyces spp. based on the previous identification of ITS1 and ITS2 at the molecular level and collected from Jocheon Miryang, Korea. To isolate and screen genes in the fungus, 626 expressed sequence tags(ESTs) were generated by a partial sequencing from the cDNA library. cDNA encoding the glyceraldehyde-3-phosphate dehydrogenase(Pt-GAPDH) of Paecilomyces tenuipes- Jocheon was cloned from the above cDNA library. The complete cDNA sequence of Pt-GAPDH is comprised of 1,014bp encoding 338 amino acid residues. The deduced protein sequence of Pt-GAPDH showed higher homology with Beauberia bassiana-GAPDH(93% amino acid identity). Hydropathy analysis revealed that Pt-GAPDH protein is hydrophilic. The major three amino acids in its composition of amino acid residues were alanine(11.54%), valine(9.47%) and glycine(8.88%). The Pt-GAPDH gene of Paecilomyces tenuipes entomopathogenic fungus consisted of three exons and two introns coding for 338 amino acid residues, and the genomic DNA length of the gene spans 1302bp. The accession number of the gene in GenBank are GU997099 for Pt-GAPDH cDNA and GU997102 for Pt-GAPDH genomic DNA. More investigation works including gene expression, immunological analysis etc. will be carried continuously without hesitation after this presentation.

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.

Objective : This study was conducted for the purpose of investigating the level exposure of welders to noise, welding fume and Manganese(Mn) related to this process. Methods and Material : All subjects in this study were welders engaged in CO2 arc and coated arc welding process especially in small-scale enterprises classified by type of manufacture of ship building, repairing and of other fabricated metal products, which is located in Gimhae and Milyang of Kyeongsang province in south Korea. Air sampling of welding fume was measured, shipped and analyzed on the basis of national institute for occupational safety and health(NIOSH) method in U.S. and work environment measurement method established in south Korea. To measure Noise in the work environment, Noise dosimeter was used on the basis of work environment measurement method established in south Korea. Result : This study was performed during a period from January, 2000 to December, 2001 and Results were as follows: 1. Noise level measured in this work environment was higher than national criteria for permissible exposure limit on health examinations related to hearing loss. 2. The concentration of welding fume and Mn in manufacture of ship building and repairing was higher than those in manufacture of other fabricated metal products. 3. In conditions of existing in ventilation system installed and operated, the concentration of welding fume and Mn was slightly lower than those of not existing. 4. In conditions of existing in sufficient air supply from out door into the work place relied on natural exhaust system, the concentration of welding fume and Mn was slightly lower than those of in not sufficient. 5. In all subjects, a rate of wearing ear plug and respiratory mask for dust and fume was lower than that of not wearing. Conclusion : According to above results, this study suggests that more positive work environment managements such as the use of portable local ventilation system, the supply of highly qualified personal protective equipment, and consecutive education and training related to health protection should be need to acquire suitable health protection program for welders engaged in small-scale enterprises in Korea.

The purpose of this research was to examine the factors, that is, chemical constituents, casing blending ratio, determination methods of filling value, grade, moisture, expansion time and tobacco variety, influencing the expansion rate of shredded tobacco. The important results obtained were as follows ; 1.Multiple regression formula about the relation of the chemical constituents to the expansion rate of shredded tobacco was statistically calculated with many experimental data attained on typical varieties. The preliminary relationship for estimating expansion rate(ER) was as follows : ER=94.2827-3.3572 (% sug) + 10.0940(% fib)-1.4316(% ash) - 1.4316(% ash)-17.2319 (fineness index) The relationship accounted for estimating approximately 95% of the observed variance of expansion rate. 2.The influence of casing blend ratio and determination methods of filling value upon expansion rate did not appear to be significant contributors in the evaluation. 3.ER was decreased toward the center position in a stalk. 4.The condition of the highest ER was 14-15% moisture contents of shred del tobacco and 90 minute of expansion time. 5.The influence of two varieties of NC82 and BY-4 on ER did not appear to be significant contributors in the evaluations.
