The simultaneous occurrence of primary gastric lymphoma and adenocarcinoma is rarely reported. We here report a case of synchronous double primary tumor of advanced gastric cancer and diffuse large B cell lymphoma. A 65-year-old woman underwent an esophagogastroduodenoscopy for the evaluation of abdominal discomfort of two months` duration. The endoscopic examination showed an ulcerating tumor in the gastric antrum and thickened folds in the fundus and the microscopic examination revealed an adenocarcinoma in the antrum and a diffuse large B-cell lymphoma in the fundus. She has had total gastrectomy and CHOP chemotherapy with rituximab. Since the cases of synchronous double primary gastric tumors have been increased on the recent medical advances, when a gastric tumor is detected for the endoscopic examination, an endoscopist has to make every endeavor not to miss another tumor in the stomach.

Takayasu arteritis is a nonspecific granulomatous inflammatory arteriopathy of unknown cause that results in occlusive obliteration and less commonly aneurysmal degeneration of large and medium-sized elastic arteries. The diagnosis of Takayasu arteritis and the assessment of its progression and extent remain challenging, especially in patients presenting with a constellation of non-specific symptoms and laboratory tests. The standard diagnostic procedures include biopsy, arteriography, sonography, and magnetic resonance angiography. However, these procedures are invasive or largely operator-dependent, and document only morphological changes such as stenosis, occlusion and aneurysmal transformation which mainly occur in late stages of the disease. On the other hand, Positron-emission tomography is an operator-independent, non-invasive metabolic imaging modality which plays a major role in diagnosis of nonspecific inflammatory diseases. We report a case in which Positron-emission tomography was applied to the detection of Takayasu arteritis and assessment of its disease progression.

갱년기의 여성에는 여러 폐경 증후들이 나타나는데, 특히 estrogen의 감소로 인한 혈중 지질 조성의 변화 등으로 심혈관계 질환의 발병율이 높아지게 된다. 본 연구에서는 실험동물로써 흰쥐를 이용하여 인위적으로 갱년기를 유도한 후 갈조류인 곰피 추출물의 영향을 혈중지질 농도, 혈소판 응집력 및 혈액 유동성을 통하여 그 효과를 검토하고자 하였다. 그 결과 갱년기유도로 인하여 증가된 혈청 중 중성지방 및 총콜레스테롤 함량은 곰피 추출물 투여에 의해 저하되었으며, 특히 곰피 추출물 200 ㎎/㎏ bw/day 투여는 중성지방 함량을 유의적으로 감소시키는 결과를 나타내었다. Ldl-콜레스테롤, 동맥경화지수(AI) 및 심혈관위험지수(CRF) 또한 곰피 추출물 투여에 의해 저하되었다 한편 Hdl-콜레스테롤 농도는 난소절제에 의해 감소하였으나, 곰피 추출물을 투여에 의해 증가되었다. 혈액의 유동성에 곰피 추출물의 효과를 실험한 결과 난소 절제에 의해 혈액의 점도가 증가하여 유동성이 저하되었으나, 곰피 추출물 투여로 인해 유동성이 향상됨을 알 수 있었다. 또한 난소 절제에 의해 혈소판 응집능이 증가하였으나, 곰피 추출물 투여로 인해 완화되는 효과를 볼 수 있었다. 이상의 결과로부터 갱년기에 나타날 수 있는 혈중 지질 변화에 대하여 곰피 추출물이 지질 및 혈행 개선 효과를 나타내었으며, 특히 곰피 추출물 200 ㎎/㎏ bw/day 투여는 모든 항목에서 유의성 있는 결과를 나타내어 곰피가 심혈관 관련성 질환 예방에 도움을 줄 것으로 기대된다. Estrogen deficiency in peri- and postmenopausal women results in variety of neurovegetative, psychic and somatic symptoms, and may contribute to severe diseases within the aged female population. Ecklonia stolonifera (ES) is an edible brown algae traditionally used in fishery towns in Far East Asia. This study was performed to investigate the effects of ES extracts on blood flow and serum lipid concentration in ovariectomized rats. Weight-matched female Sprague-Dawley strain rats were assigned to four groups. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Rats were randomly assigned to the following groups: sham-operated rats (Sham), ovariectomized control rats (OVX-CON), ovariectomized rats supplemented with ES extract at 50 ㎎/㎏ bw/day (OVX-ES50) and ovariectomized rats supplemented with ES extract at 200 ㎎/㎏ bw/day (OVX-ES200). Serum total cholesterol and triglyceride contents decreased in the sham group compared to the OVX-CON group. Six weeks feeding of ES extract resulted in a significant (p<0.05) lowering of serum triglyceride and a lowering tendency of total cholesterol level. The level of Hdl-cholesterol in serum increased by supplementation of ES extracts at 50 ㎎/㎏ and 200 ㎎/㎏ bw/day (p<0.05). Blood passage time of the ES extracts-supplemented group was higher than the OVX-CON group. The ability of platelet aggregation of groups treated with ES extracts was less than that of the OVX-CON group. These results suggest that the beneficial effects of ES extract may be used to possibly improve on the metabolic syndrome of menopausal women.

Etanercept is a soluble receptor fusion protein that inhibits tumor necrosis factor-alpha(TNF-α). The receptor is used widely in the treatment of ankylosing spondylitis, rheumatoid arthritis, sarcoidosis and other indications. For sarcoidosis, it potentially suppresses granuloma formation with TNF-α blocking. On the other hand, recent studies have suggested that paradoxical sarcoidosis can be induced by TNF-α antagonists in some cases. A 42-yearold woman, who was treated with etanercept due to ankylosing spondylitis for 5 years, was admitted because of right suprahilar lymphadenopathy on chest radiography. Chest computed tomography revealed an enlargement of supraclavicular, paratracheal, mediastinal lymph nodes. She was diagnosed with sarcoidosis on the supraclavicular lymph node biopsy, which was non-caseating epithelioid cell granuloma and excluded from similar diseases. She was treated for sarcoidosis with prednisolone instead of etanercept.
