Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and ≥ 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 ± 8.0 yr) was significantly higher than that of ≥ 25 months group (62.2 ± 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in < 25 months group and the amounts of alcohol consumption were significantly higher in ≥ 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

목적: hNIS는 갑상선 조직 외에 다른 조직들에서도 발현된다고 알려져 있다. 유방암 세포는 그런 조직들 중에 하나이며, 그에 의한 유방암의 방사성옥소치료의 가능성이 제시되고 있다. 본 연구에서는 유방암 조직에서 hNIS의 발현정도를 알아보고, ^99mTc-MIBI 유방스캔과 hNIS의 발현 정도와의 관계를 조사하여 보았다. 대상 및 방법: 본 연구에서는 유방암으로 수술을 시행했던 56명의 환자를 대상으로 하였다. hNIS의 발현은 면역조직화학염색에 의해서 평가되었으며, 그 결과를 ^99mTc-MIBI 유방스캔의 판정 결과와 비교하였다. 결과: 전체 56명의 환자에서 hNIS의 발현율은 41.1%였다. 병리학적 진단에 의해 침윤성관상피암종이었던 49명에서의 발현율은 42.9%, 관상피내암종이었던 7명에서의 발현율은 28.6%였다. ^99mTc-MIBI 유방스캔에서 국소섭취 소견이 관찰되었던 41명에서의 hNIS의 발현율은 31.7%였다. 비정상적인 섭취 소견이 관찰되지 않았던 15명의 환자에서의 hNIS의 발현율이 의미있게 높게 관찰되었다(66.7%, p>0.05). 결론: 유방암 환자에서의 hNIS의 발현율은 그다지 높지 않았다. ^99mTc-MIBI 유방스캔에서 섭취증가 소견이 없을 때 hNIS의 발현율이 더 높았다. Purpose: Human Na^+/I- symporter (hNIS) is known to be expressed in many tissues other than thyroid gland. The breast cancer cells are one of them and the possibility of radioiodine therapy in treatment of the breast cancer may be suggested. We investigated the expression rate of hNIS and the relationship between the expression of hNIS and the finding of 99mTc-MIBI scintimammography in the breast cancer. Materials and Methods: Surgically proved 56 patients with breast cancer were the subjects of this study. The expression of hNIS were evaluated by immunohistochemistry and the results were compared to the findings of 99mTc-MIBI scintimammography. Results: Overall expression rate of hNIS was 41.1% in 56 patients. According to the pathologic diagnosis, it was 42.9% in 49 patients with invasive ductal carcinoma and 28.6% in the 7 patients with ductal carcinoma in situ. The expression rate of hNIS in the 41 cases with a focal increased uptake at he breast lesion on 99mTc-MIBI scintimammogram was 31.7%. That in the 15 cases without any abnormal uptake on the scan was significantly higher(66.7%, p<0.05). Conclusion: The expression rate of hNIS in the patients with breast cancer was not so high. The rate was higher in the patients with no increased uptake at the breast lesion on 99mTc-MIBI scintimammography. (Korean J Nucl Med 2002;36;325-32)

수중식물과 침전물에 의한 용존산소 변화량 결정 : 하천모델 이용법;a Stream Model Approach

이용석,최은주,박민대,박석순 江原大學校 附設 環境硏究所 1993 環境硏究 Vol.10 No.-

하천모델을 이용하여 한강 지류인 탄천에서 수초와 침전물에 의한 용존산소 변화량을 측정하였다. 수질자료에 따르면 탄천은 상류의 부영양화 지역 (Eutrophic Zone)과 하류의 강부수성 지역 (Polysaprobic Zone)으로 구분되며 상류는 수초의 광합성과 호흡이, 하류는 침전물 산소요구량이 수중 용존산소 농도 결정에 주 역할을 하고 있다. 하천조사는 1990년5월과 10월 2회에 걸쳐 2일간 연속적으로 실시되었다. 조사 결과 상류의 경우 수초 광합성과 호흡에 의한 매우 큰 용존산소 일주변화가 관찰되었다. 그러나 하류의 경우 침전물 산소요구량이 크고 수초 성장이 없기 때문에 일주변화가 거의 나타나지 않는 매우 낮은 농도가 측정되었다. 1차 조사시 상류에서 수중식물의 광합성량과 호흡양은 각각 55~100g 0₂/m²/day, 30~70g 0₂/m²/day으로 측정되었으며, 2차 조사시 각각 40~80g 0₂/m²/day, 25~55g 0₂/m²/day으로 측정되었다. 하류에서는 침전물 산소요구량이 1차 및 2차 조사시 동일하게 4~100g 0₂/m²/day로 측정되었다. The dissolved oxygen changes caused by aquatic plants and sediments were comput-ed in the Tancheon, a tributary of the HanRiver, by utilizing a stream model. According to the collected water quality conditions, the Tancheon was classified into two distinc-tive zones which were eutrophic zone in upstream area and polysaprobic zone in downstream area. The dissolved oxygen levels of the stream were determined mainly by the photosynthesis and respiration of the macrophytes in upstream area and by the sediment oxygen demand in downstream. Field data were obtained from two synoptic stream surveys performed during May and October, 1990 for two consecutive days The high diurnal dissolved oxygen variation was observed in upstream area due to an excessive growth of aquatic plants. In downstream area, however, little diurnal varia-tion with low dissolved oxygen level was observed, which would be attributed to high sediment oxygen demand and no discernible aquatic plant growth. In upstream area, the dissolved oxygen changes caused by the photosynthesis and respiration were ranged from 55g 100g 0₂/m²/day from 30 to 70 g 0₂/m²/day, respectively, during the first survey. The changes were ranged from 40 to 80g 0₂/m²/day for the photosynthesis and from 25 to 55g 0₂/m²/day for the respiration during the second survey, In downstream area, the sediment oxygen demands were measured from 4 to 100g o₂/m²/day during both surveys.

For the purpose of development of a liquid membrane permeator which separates metal ions from aqueous solutions continuously and effectively, a continuous membrane permeator with the membrane solution trapped between extraction and stripping phases by two micro-porous hydrophilic films was manufactured. Experimental researches on the separation of zinc ion from aqueous solutions were performed in the liquid membrane permeator with 30 vol % D_2EHPA solution in kerosine as liquid membrane. As results, the liquid membrane permeator separates zinc ion from aqueous solutions continuously and effectively in the wide range of operating conditions. A simple mass transfer rate model using equilibrium constant of the extraction reaction for the system used were proposed, and the model was compared with experimental results of separation of zinc ion in the permeator. And the effects of operating factors, such as space time, pH of extraction solution, extraction temperature, on the separation rate of zinc ion in the permeator were experimentally examined.
