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.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

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.

본 연구에서는 구강환경과 유사한 액상의 조건하에서의 온도변화가 광중합형 글래스아이오노머계 수복재의 인장강도에 미치는 영향을 평가하기 위해 대조군으로 2종의 재래형 glass ionomer를 선택하고 실험군으로 2종의 광중합형의 resin-modified glass ionomer와 2종의 polyacid-modified resin composite을 선택한 다음 수중에서의 thermal cycling과 시효처리를 행하였으며, 다음과 같은 결론을 얻었다. 1. 글래스아이오노머 수복재의 인장강도를 측정한 결과, polyacid-modified resin composite, resin-modified glass ionomer 그리고 재래형 glass ionomer의 순으로 나타났다. 2. 인장강도는 30일간의 시효처리로 증가되는 경향을 보였다. 3. 재래형 glass ionomer 수복재의 인장강도는 thermal cycling 처리로 증가되는 경향을 보였으며, 37℃의 증류수 중에 1시간 침적한 군과 10,000회의 thermal cycling을 비교한 결과 유의한 차이로서 강도의 증가를 나타냈다(P<0.01). 4. thermal cycling 군의 인장강도는 DR군이 45.4MPa로 최대치를, FL군이 13.4MPa로 최소치를 나타냈으며, 각 군간의 통계적 유의성을 검증한 결과 polyacid-modified resin composite의 인장강도가 나머지 군과 유의한 차이를 보였다(p<0.05). 5. 특성강도는 DR군이 48.6MPa로 가장 높은 강도치를 보였으나, Weibull 계수는 CG군이 8.9로 가장 높은 값을 보여 시험재료 중에서 가장 작은 강도의 분산을 나타냈다. This study was performed to evaluate the effect of aging and thermal cycling on the tensile strength of six commercially available glass-ionomer materials: two chemically set glass-ionomer materials(Fuji Ⅱ, fuji Ⅸ), two resin-modified glass-ionomer materials(Fuji Ⅱ LC, Vitremer), and two polyacid-modified composite resins(Compoglass, Dyract). Rectangular tension test specimens were fabricated in a teflon mold giving 5mm in gauge length and 2mm in thickness. All samples were divided into 3 groups. Group 1 was immersed in a 37℃ distilled water for 1 hour. Group 2 was immersed in a 37℃ distilled water for 30 days. Group 3 was subjected to 10,000 thermal cycles between 5℃ and 55℃, and the immersion time in each bath was 15 seconds per cycle. Tensile testing was carried out at a cross-head speed of 0.5mm/min and fracture surfaces were examined with scanning electron microscope. The results obtained were summarized as follows; 1. The polyacid-modified composite resins were stronger than the resin-modified glass-ionomer materials, which were much stronger than the conventional glass-ionomer materials. 2. Tensile strengths were slightly increased after aging treatments for 30days. 3. Tensile strengths of conventional glass ionomers were significantly increased after thermal cycling treatment(p<0.01). 4. The highest tensile strength value of 45.4MPa was observed in the Dyract group and the lowest value of 13.3MPa was observed in the Fuji Ⅱ LC group after the thermal cycling test, and the strengths of polyacid-modified composite groups were significantly higher than those of other groups. 5. The highest characteristic strength value of 48.6MPa was obtained in the Dyract group, however the highest Weibull modulus value of 8.9MPa was obtained in the Compoglass group after thermal cycling test.

마우스의 BCG감염이 R.tsutsugamushi의 증식에 미치는 영향

It has recently been reported that gamma-inteferon(INF-r) and tumor necrosis factor(TNF) or lipopplysaccharide(LPS) activate macrophages to kill intracellular parasites by means of nitrc oxide (NO). It is now generally accepted that NO is the endothelium-derived relaxing factor, and that it also paticipates in the regulation of the nervous and immune systems. Activated macrophages form NO?? and NO?? from the terminal guanidino nitrogen atoms of L-arginine by the process now known to proceed via the formation of NO. This pathway is inhibited by the L-arginine analog(N?? monomethyl-L-arginine; N??MMA), forms L-citrulline as a co-product and is responsible for the cytotoxic action of macrophages. In this study, the authors found that INF-r and/or LPS induced murine macrophages to kill Rickettsiae tsutsugamushi in vitro and macrophages from BCG-infected mice got the host resistance against R.tsutsugamushi in vitro as well as in vivo. The rickettsicidal effect induced by the combination of INF-r and/or LPS induced mice got the host resistance against R.tsutsugamushi in vitro as well as in vivo. The rickettsicidal effect induced by the combination of INF-r and/or LPS can also be completely inhibited by N??MMA, leading to a dose-dependent inhibition of NO production. These datademonstrate that INF-r and/or LPS as well as BCG-activated macrophages mediate host resistance aganist R.tsutsugamushi infection through NO, which is necessary for the intracellular parasite.

1851년 런던 세계 산업박람회와 팍스톤의 건축

The Exhibition Hall or the first World Exposition in London 1851 was designed by Joseph Paxton, who was nor architect neither engineer. The building is enormous big in its dimension and was erected in very short time of 6 months. Although the crystal Palace got a welcoming reputation in the mass media, it was not regarded as a architecture by the contemporary leading architects, for example - Pugin and Ruskin. The process of becoming architecture is to understand as a architectural reaction on the certain need of society, that has characteristic of change through the time. In this aspect Paxton's reaction with his the crystal Palace is very notable and meaningful to investigate the essential interaction between architects and society.
