OBJECTIVES: To compare the late complications after operations for rectal cancers with and without preoperative chemoradiation. METHODS: From January 2003 to December 2005, 55 patients underwent operation after preoperative chemoradiation for adenocarcinoma of the rectum. All of them received the full scheduled dose of radiation with concurrent chemotherapy. The interval between preoperative chemoradiation and surgery was 4-6 weeks. 47 patients who had tumors below 8 cm from the anal verge were enrolled into the study group (CRT group). During same period, we selected 153 patients who had adenocarcinoma of the rectum below 8cm from the anal verge, underwent surgery alone without postoperative radiotherapy non-CRT group). We compared the early and the late postoperative complications between the CRT group and the non-CRT group. RESULTS: Of the late complications, the incidence of anastomotic stricture was significantly higher in the CRT group (P = 0.018). The incidence of anal stricture was higher in the CRT group (P = 0.164). In the CRT group, 3 cases (17.6%) had failed to preserve the anal function due to moderate or severe anal stricture. Of the 3 cases, protective ileostomy was persistent in 2 cases, colostomy was performed in one case. Otherwise, the late complications of the CRT group were intestinal obstruction in 2 cases (4.3%), lymph edema in 2 cases (4.3%). CONCLUSION: In CRT group, failure of anal function preservation due to anastomotic stricture or anal stricture was more common and serious than non-CRT group. We emphasize the need for careful management for postoperative anal stricture after preoperative chemoradiation.

재해가 발생하면 신속한 피해복구 대책을 수립하기 위해서는 무엇보다 먼저 재해지역에 대한 신속하고 정확한 조사가 실시되어야 한다. 본 연구는 저수지 붕괴에 따른 원인분석을 체계적으로 실시하여 특히 수해발생시 수행되어야 분석의 기준을 제시하고 자 한다. 경상북도 안동시에 위치한 공실 지는 2000년 8월 26일 호우로 인하여 8월 27일 01:00 (추정시각)에 우안 여수로에서 좌안 부분 상 약 5m, 하부 약 3m, 정도가 유실되어 농경지와 가옥의 침수피해가 발생하였다. 이 붕괴사상을 대상으로 붕괴에 따른 피해 및 원인 분석을 현장조사와 수문해석 및 토양 및 지질분석을 통하여 실시하였다. 수문해석 및 흔적조사에서도 저수지 제방의 월류의 가능성은 적으며, 지속적인 여수로와 저수지 제체 연결부로 침투가 이루어져 저수지 제체가 불안정한 상황 하에 갑작스러운 호우로 인하여 침투량이 증가하여 과잉공극수압의 증가로 인하여 파괴가 발생한 것으로 판단된다. To prepare measures for dealing with disasters, the exact investigation for disaster area have to take effect. In this study, the factors leading to reservoir break are analyzed, and set a standard analysis in carrying out reservoir break. The Kongsil reservoir located in Andong City was breaked in a localized torrential downpour at Aug. 27, 2000. As the result of the Kongsil reservoir break, submerged farm land and house occurred in the downstream area. The damage analysis caused by Kongsil reservoir break was performed through field investigation, hydrologic and geological analysis. The reservoir bank have been unstable by infiltration into joined area of spillway and reservoir embankment. Consequently, The reason of the Kongsil reservoir break is supposed that a sudden increase of infiltration into unstable embankment led to increase of excess pore pressure.

In this study, an analytical procedure was evaluated for the determination of atmospheric PAH, both in gaseous and particulate phases. The method involves Soxhlet extraction of the filters and Tenax adsorbent, followed by a clean-up stage using a silica mini column prior to analysis by reversephase HPLC with wavelength programmable fluorescence and UV detection. A total of 18 PAH were identified and quantified, all of which have been of environmental concern. In order to validate the methodology and to ensure compatibility of the results, the analytical method used for the determination of PAH was evaluatd with respect to the efficiencies of extraction and clean-up procedure, HPLC separation, and lower limits of detection. In addition, substrate dependency of PAH recovery was also investigated for the two type of filter(glass fiber and PTEF filters) and Tenax adsorbent.

양희태,정승일,이영철,윤경아,백승화 한국식품영양학회 2002 韓國食品營養學會誌 Vol.15 No.1

고삼 메탄올 추출물로부터 분리한 flavonoids를 IR, NMR등의 분광학적인 방법으로 Leachianone A(LA)과 Sophoraflavanone G(SFG)로 동정하였고, 카드뮴의 세포독성효과를 고삼 및 고삼추출물이 방어할 수 있는 지를 검색하기 위하여 NIG 3T3 세포에 고삼 및 LA와 SFG, LA+SFG를 처리하고 MTT assay 및 광학현미경으로 세포의 생존률을 검색하여 다음과 같은 결론은 얻었다. MIT의 흡광도는 카드뮴의 농도에 의존하여 감소하였으며, IC_50인 MTT50은 12.5??이었으며 카드뮴을 IC_50농도로 처리하고 고삼 및 LA, SFG, LA+SFG를 각 화합물의 자체 세포독성을 갖지 않는 농도로 처리한 후 MTT assay로 세포 생존율을 측정한 결과 LA, SFG, LA+SFG 처리군들은 카드뮴 처리군(MTT_50)에 비해 세포생존률이 증가되었으며 이들은 고삼 및 고삼추출물의 농도에 의존적으로 증가되었고 각각의 단일 화합물보다 두 화합물 LA+SFG 병용처리군에서 수복 효과가 더 좋은 것으로 나타났으며 광학현미경적 소견에서도 세포재생이 뚜렷하게 보였다. 이상과 같이 고삼에서 분리한 flavonoids가 카드뮴 독성에 의하여 손상된 NIH 3T3 섬유아세포의 재생효과에 영향이 있는 것으로 판단된다. The aim of this study was to assess the antitoxic compounds, flavanones (Leachinanone A=LA and Sophora flavanone G=SFG), from Sophora flavescents (S. Flavescens). We investigated the possibility of antitoxicity of LA and SFG against NIH 3T3 fibroblasts cell lines using colorimetric MTT[3-(4-5-dimethylthiazol-2-yl)-2-5diphenyl-2H-tetra-azolium bromide] assay. The results were as follows : After cadmium was treated against NIH 3T3 cell lines, we determined IC_50. Accordingly we have examined the detoxification effects of S. flavescens, LA and SFG under cadmium IC_50=12.5?? and was carried out to observe morphological changes by the light microscopic study. In NIH 3T3 cells, Sophora flavescens, LA, SFG and LA+ SFG showed inhibitory effects on the cytotoxicity of cadmium and these detoxication effects increased in proportion to the concentration of these drugs. These results suggest that LA and SFG from S. flavescens retain a potential antitoxic activity.
