Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

Background : The safety and effectiveness of influenza vaccine are well known in developed country. The influenza vaccination has been recommended as one of the tentative immunization schedule for indicated persons since 1997 in Korea. But there are still no available data about them, even though nearly 5 million doses of influenza vaccine were used in 1997-1998 season. So it is immediately needed to investigate the safety. efficacy and immunogenicity of influenza vaccine among Korean. Methods : We studied the clinical efficacy of influenza vaccine by monitoring Occurrence of influenza-like illness in influenza risk group(vaccination ; 300, non-vaccination; 215) from December in 1997 to March in 1998. We used the split quadrivalent influenza vaccine containing 15 microgram of hemagglutinin of A/Beijing/262/95(HlNl), A/Wuhan/359/95(H3N2), B/Mie/1/93 and B/Guangdong/5/94. Hemagglutination inhibition(HA1) antibody titers were determined before immunization and 1 months after vaccination And we evaluated adverse effect of influenza vaccination at 7 days after vaccination. Results : Influenza vaccination was associated with si@icant reductions in influenza-like spptoms(vaccination group; 28.35%, non-vaccination group, 35.88%, p=0.001). The preventive effect of influenza-like i3lne.s among influenza risk goup was 20.97%. And immunogenicity of influenza A and B exceeded all of the European licensure criteria for immunogenicity except postvaccination proportion of titers 240 of B/Guangdong/5/94 strain. And the adverse effects were mainly local injection site problem and no serious adverse effect was noted. Conclusion : Split influenza vaccine is safe, inmunogenic and eff'tive in influenza risk group in Korea.

연구목적: 여성 요도증후군을 보이는 환자에서 교감신경차단제인 terazocin을 복용한 후 치료 효과에 대한 각 증상의 변화와 부작용을 알아보고자 하였다. 대상 및 방법: 1997년부터 1999년까지 충북대학교병원 비뇨기과에 내원한 35명의 여성 중 요검사 및 요배양 검사, 그리고 다른 이학적 검사에서 이상이 없는 요도증후군 환자를 대상으로 간질성방광염 증상점수(ICSS)를 terazocin (3mg/day for 3 months) 투여 전후에 조사하였고, 치료 후 3개월과 1년에 Likert scale 점수를 조사하였다. 결과: ICSS는 비치료군은 18.3±5.9점, 치료군은 16.5±6.8점으로 두군간의 차이는 없는 것으로 나타났다(p=0.52). 치료군은 치료 후 3개월에 시행한 ICSS가 9.9±7.8점으로 치료 전에 비해 현격히 증상이 호전되는 것으로 나타났다(p=0.0001). 특히 3개월에 시행한 Likert scale에서는 주간 및 야간빈뇨, 절박뇨, 배뇨통의 횟수 및 강도, 그리고 전체적인 증상정도에서 40-70% 가량 호전된 것으로 밝혀졌으며 이는 1년 후에도 증상의 호전이 지속되는 것으로 나타났다. 비치료군에서의 1년 후 Likert scale은 6명 중 2명이 전체적인 증상의 호전이 있는 것으로 나타났다. 결론: Terazocin은 환자의 약 70%가량에서 증상의 호전을 가져왔고, 비치료군에서도 환자의 33%가 저절로 증상이 좋아진 것으로 보아 Terazocin은 여성 요도증후군에서 분명히 효과가 있으나 증상이 심할 경우 보조적인 치료로 이용되는 것이 바람직할 것으로 사료된다. Purpose: We performed to assess the effects and complications of terazocin in women with chronic female urethral syndrome. Materials and Methods : Thirty-five women with chronic female urethral syndrome were studied from March 1997 to August 1999. The subjects exhibited normal findings without the pyuria and bacteriuria in urinalysis and urine culture and were invested the interstitial symptom score(ICSS). 29 subjects of them took a terazocin 1-4 mg/day for 3 months. They were reevaluated for the ICSS and Likert scale after 3 months and for Likert scale after 1 year. Results: The ICSS before treatment were showed 18.3±5.9 in the untreated patient group and 16.5±6.8 in the treated patient group, and no statistically difference between both patient groups(p=0.52). In the treated patient group, the ICSS after treatment were showed 9.9±7.8, significant difference between before and after treatment(p=0.0001). The Likert scale was showed at 3 months after treatment that frequency, nocturia, urgency, pain frequency, pain intensity, daily activities, and overall symptoms were improved in 65.5%, 55.2%, 24.1%, 41.4%, 41.4%, 70%, 70%, and 70% of 29 subjects, each other. Overall symptom score assessed at 1 year were showed that 3 subjects was aggravated. In untreated patient group, 2 of 6 was improved in overall symptom score. Conclusion: Terazocin was effective above 70% in the treated group, and symptoms were improved spontaneously in a third of the untreated group. So, we thought that terazocin would be useful as supportive treatment in period of severe symptoms.

In this paper, a new type of wavelength converter using XPM within a loop-mirror is proposed and demonstrated. The proposed structure decreases hardware components for implementation of XPM wavelength converter and makes it possible to get non-inverted and inverted output signals simultaneously. Also, we generate wideband pumping mode series for FWM wavelength conversion scheme and propose the effective filtering method for selecting converted wavelength from FWM outputs. The results show that the pumping mode range is over 30nm within 5dB power fluctuation, and that a pumping and a prove wave can be removed successfully by using both of Michelson interferometer and polarization controller.

왕겨에 200, 400, 600, 800 및 1000 Gy의 저선량의 감마선을 조사하여 항산화능의 변화를 관찰하였다. 총 페놀 화합물의 양은 무처리구의 경우 0.184 mM를 나타내었고, 200 Gy로 감마선을 조사하였을 때는 0.215 mM로 약간 증가함을 보였으나 이후 차츰 감소하였다. 전자 공여능은 무처리구에 비해 처리구의 경우 조사 선량별로 조금씩의 차이만 있을 뿐, 조사 선량에 대한 왕겨의 전자 공여능은 유의적인 큰 변화 없이 비슷한 활성을 보였다. Fe^2+-ions 킬레이팅 활성은 무처리구의 경우 68.25%를 나타내었으며, 200, 400, 600 및 800 Cy 에서는 각각 86.45, 85.61, 86.65 및 82.84%로서 무처리구보다는 증가함을 보였으나, 1000 Gy에서는 74.67%로 감소하였다. 지질 과산화 억제능은 무처리구에 비해 처리구는 약간의 증가를 보였으나 효과는 미비하였다. We studied the effect of small-dose of γ-irradiation to rice hull(RH) for its antioxidant ability. The RH was treated with 200, 400, 600, 800, and 1000 Gy of γ-ray at 70 Gy/min. Total phenol amount of unirradiated RH was 0,184 mM, after irradiation at 200 Gy it increased to 0,215 mM, while irradiation above 400 Gy up to 1000 Gy decreased that to unirradiated level. The electron donating ability of RH did not show significant change depend on irradiation. The chelating ability for Fe^2+ of unirradiated RH was 68.25 %, while that of 200, 400, 600 and 800 Gy irradiated RH showed 86.45, 85.61, 86.65 and 82.84 % respectively, but, 1000 Gy was decreased to 74.67 %. According to TBARS analyses, inhibition ability of lipid peroxidation by RH was not affected by γ-irradiation.

鄭鉉雨,康城溶,白承化 대한본초학회 1999 大韓本草學會誌 Vol.14 No.2

Rhizoma Acori Graminei(RAG) has been used in Korea for many centuries as a therapeutic agent for cerebral disease. The effect of RAG on the vascular system is not known. The purpose of this study was to determine the effect of RAG on Blood Pressure(BP) and regional Cerebral Blood Flow(rCBF) of male Sprague-Dawely rats. The changes in rCBF were determinated by Laser-Doppler Flowmetry(LDF). The results were as follows : 1. Blood pressure was not affected by RAG in rats. 2. rCBF was increased by RAG in a dose-dependent manner. 3. Pretreatment with propranolol significantly inhibited RAG induced increased rCBF. 4. Pretreatment with methylen blue and ODQ significantly inhibited RAG induced increased rCBF. 5. Pretreatment with L-NNA significantly inhibited RAG induced increased rCBF. These results suggest that RAG causes a diverse response of blood pressure and regional cerebral blood flow(rCBF). The increased in rCBF is also mediated by adrenergic β-receptor, nitric oxide synthease and guanylate cyclase.

The colorectal corcinoma is one of the most common malignant tumor in Korea and its carcinogenic mechanism has not been elucidated exactly yet. So far, the most common carcinogenic mechanism has been known to be multiple genetic changes. But, the CpG island hypermethylation has been revealed to be one of the most important carcinogenic mechanism second to the genetic changes. The epigenetic changes characteristically imprint and transfer to the next generation without changes of nucleotide sequences. When the CpG island of promoter or 5'- exon 1 of a specific gene is methylated by DNA methyltrasferases (DNMTs), the gene expression is inhibited. Carcinogenic mechansisms by promoter methylation has been well known, but the progression of the cancer has not been elucidated yet. The molecular researches on the carcinogenic mechanisms largely depended on the tumor tissue containing various components of cell, due to difficulties in harvesting pure homogeneous tumor cells. Promoter methylatonof the cancer related genes as APc, hMLH2, p16, DAP-K and MGMT in 50 cases of sporadic colorectal carcinoma was studied. The pure normal colorectal epithelial cells, and cancer cells from superficial and deep invasive portion were harvested respectively by laser captured microdissection(LCM), and DNA was extracted from them. The promoter methylation was studied by methylation specific poymerase reaction (MSP) after bisulfite modification of the DNA and the expression of the genes by immunohistochemistry. The results suggests that promoter methylation of the cancer related genes are closely related with the colorectal carcinogenesis and it occurrs from early phase of carcinogenesis, progressing constantly to the late stage. And the promoter methylation of normal epithelial cells increased by age. The p15, known to be the genes related to hematologic malignancy, was closely related to the colorectal carcinoma as well.

The study aims to have cognizance of middle-aged mental and physiological properties by means of presenting the feature of physical strength, and to make middle-aged people try to prevent symptoms of senility and live a healthy and beneficial life for the rest of their days by means of showing a program of physical exercise suitable for middle-aged people. According to the middle-aged feature of physical strength, the decline of physical strength and physilogical function was remarkable. Individual variation in physical strength was wide and bodily organization was likely to get damaged easily as one attains an advanced age. Middle-aged people was slower in revovering and blood pressure was higher than young one after the same physical exercise. In conclusion, middle-aged people must build up his physical strength and try to prevent symptoms of senility through light physical exercises rather than heavy ones.

본 연구에서는 시판되고 있는 식초를 이용하여 6종의 식품 유해세균에 대한 항균력을 비교하였다. 그 결과, 감식초와 현미식초는 합성식초에 비해 S. aureus, M. luteus, S. enteritidis 및 E. coli에서 항균 활성이 높게 나타났으며, 현미식초가 감식초에 비해 식품유해세균에 대한 항균활성이 비교적 더 높게 나타났다. 현미식초의 농도에 따른 항균활성을 조사한 결과 5종의 그람양성 세균 및 음성 세균 모두 10μm/mL 이상의 농도에서 생육이 거의 억제되었으나, V. parahaemolyticus는 15 μm/mL 농도에서 생육이 거의 정지되어, 현미식초는 식품 부패균과 대장균 생육억제에 우수한 것으로 나타났다. 식초처리에 의한 미생물의 형태 변화를 전자 현미경으로 관찰한 결과 S. aureus, E. coli 모두 세포가 팽윤되고 일부 세포벽이 완전히 파괴된 형태를 관찰할 수 있어 식초처리로 인해 세균의 생육이 억제되는 것을 알 수 있었다. We investigated antimicrobial effects of commercial vinegar on the harmful food-born organisms. As a result, antimicrobial effects of brown rice vinegar showed stronger than persimmon and artificial vinegar. In 10μL/mL concentration of brown rice vinegar was completely inhibited about 5 strains except for V. parahaemolyticus, it was inhibited 15 μL/mL concentration. Therefore vinegars were effective for inhibition acitivity against foodborne organisms. S. aureus and E. coli treated with 25μL/mL concentration brown rice vinegar was observed by scanning electron micrographs(SEM). The cells were expanded and a part of cell wall was completely destructed by brown rice vinegar.
