본 연구는 수용액중의 중금속에 대하여 녹차를 이용하여 흡착능을 고찰하였다. 실험에 사용된 녹차는 시판되는 "태평양화학 설록차(2번차)"를 40∼60mesh로 만들어 사용하였다. 각 중금속이온을 함유한 시료용액에 녹차를 첨가하여 흔든 다음, 원심분리해서 상등액중의 각 이온농도를 원자흡광광도계로 측정했다. 그 결과, 각 조건에서 녹차에 의한 중금속의 최대흡착율은 Cu(Ⅱ)는 65∼78%, Cd(Ⅱ)는 78∼82%, Pb(Ⅱ)는 82∼92%였으며, 반응초기 10분간에 최대흡착율의 90%가 일어났다. The adsorptivities of the green-tea particles on Pb(Ⅱ), Cd(Ⅱ) and Cu(Ⅱ) ions were examined by measurements of the adsorption percentage under various conditions, and the method to collect and remove the metallic ion in aqueous solutions were described. Each of 100ml sample solution of Pb(Ⅱ),Cd(Ⅱ) and Cu(Ⅱ) ions mixed with 2g of the green-tea under stirring for minutes. The solutions were then centrifuged, and the concentrations of Pb(Ⅱ), Cd(Ⅱ), and Cu(Ⅱ) ions in the supernatant solution were determined by the atomic absorption spectrometer. As the results, the adsorption equilibrium of Pb(Ⅱ), Cd(Ⅱ) and Cu(Ⅱ) ions were reached to equilibrium by shaking for about 30∼40minutes. Then adsorptivities were 84%, 79% and 65% respectively.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

Background: Inverted colonic diverticula (ICD) are rarely reported. ICD can be confused with elevated polypoid lesions and are occasionally complicated by bleeding and colonic perforation following biopsy or endoscopic resection. We report a case of inverted diverticulitis of ascending colon misdiagnosed as subepithelial tumor. Case report: A 61-year-old man, who had history of adenomatous colon polyps and an about 3.5 cm sized subepithelial tumor in the ascending colon 5 years ago, presented for surveillance colonoscopy. He had no symptoms. Physical examination and laboratory data were normal. On follow-up colonoscopy, subepithelial tumor without change in size showed a central necrosis communicating to surface in ascendingcolon. Biopsies revealed chronic infl ammation and elongated crypts without evidence of malignancy. The abdominal CT showed 4 cm sized segmental wall thickening with enhancement in proximal ascending colon. A laparoscopic right hemicolectomy was performed to rule out malignant transformation of subepithelial tumor. Intraoperative fi ndings revealed an infl ammatory mass in proximal ascending colon. Histopathologic evaluation revealed a 3.5x3.0 cm sized diverticulum with multiple mucosal invaginations containing inspissated mucoid materials, congested subserosa and fi brinous exudated serosa without malignancy -The fi nal diagnosis was inverted colonic diverticulitis of ascending colon. Two years ago, on further history taking, patient had an episode of right lower quadrant abdominal pain, which was misdiagnosed as an infectious enterocolitis and resolved with conservative management. Maybe it was thought to be due to colonic diverticulitis. Conclusion: Because ICD may resemble polypoid lesions in the colon, they should be considered in the differential diagnosis of unusual polypoid lesions by additional imaging studies such as EUS and CT. To our knowledge, this is the fi rst case of ascending ICD complicated with diverticulitis.

Inferior mesenteric arteriovenous fistula is rare and may be congenital or acquired. Affected patients present with abdominal pain, mass, or manifestations of portal hypertension and bowel ischemia. Until now, inferior mesenteric arteriovenous fistula due to trauma has not been reported. Herein, we report a case of a 53-year-old woman who had inferior mesenteric arteriovenous fistula considered to have originated from remote blunt trauma that was successfully treated by surgical resection of only the arteriovenous fistula without colectomy. To our knowledge, this is the first case of traumatic inferior mesenteric arteriovenous fistula. (Korean J Gastroenterol 2013;62:296-300)

<P>Interferon (IFN)-induced signalling pathways have essential functions in innate immune responses. In response to type I IFNs, filamin B tethers RAC1 and a Jun N-terminal kinase (JNK)-specific mitogen-activated protein kinase (MAPK) module--MEKK1, MKK4 and JNK--and thereby promotes the activation of JNK and JNK-mediated apoptosis. Here, we show that type I IFNs induce the conjugation of filamin B by interferon-stimulated gene 15 (ISG15). ISGylation of filamin B led to the release of RAC1, MEKK1 and MKK4 from the scaffold protein and thus to the prevention of sequential activation of the JNK cascade. By contrast, blockade of filamin B ISGylation by substitution of Lys 2467 with arginine or by knockdown of ubiquitin-activating enzyme E1-like (UBEL1) prevented the release of the signalling molecules from filamin B, resulting in persistent promotion of JNK activation and JNK-mediated apoptosis. These results indicate that filamin B ISGylation acts as a negative feedback regulatory gate for the desensitization of type I IFN-induced JNK signalling.</P>

Plant pathogenic RNA viruses are present in a variety of plant-based foods. When ingested by humans, these viruses can survive the passage through the digestive tract, and are frequently detected in human feces. Kimchi is a traditional fermented Korean food made from cabbage or vegetables, with a variety of other plant-based ingredients, including ground red pepper and garlic paste. We analyzed microbial metatranscriptome data from kimchi at five fermentation stages to identify plant RNA virus-derived sequences. We successfully identified a substantial amount of plant RNA virus sequences, especially during the early stages of fermentation: 23.47% and 16.45% of total clean reads on days 7 and 13, respectively. The most abundant plant RNA virus sequences were from pepper mild mottle virus, a major pathogen of red peppers; this constituted 95% of the total RNA virus sequences identified throughout the fermentation period. We observed distinct sequencing read-depth distributions for plant RNA virus genomes, possibly implying intrinsic and/or technical biases during the metatranscriptome generation procedure. We also identified RNA virus sequences in publicly available microbial metatranscriptome data sets. We propose that metatranscriptome data may serve as a valuable resource for RNA virus detection, and a systematic screening of the ingredients may help prevent the use of virus-infected low-quality materials for food production.
