이정숙,정민철,김우식,이근철,김홍중,박찬선,이헌주,주윤정,이근종,안종석,박완,박용하,민태익 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

목적 : HBV-DNA를 정성적 그리고 정량적으로 검출함으로써 강한 전염성과 높은 유병율로 인해 사회적으로 문제가 되는 B형 간염과 원발성간암의 연관성을 알아보고자 하였다. 대상 및 방법 : B형 간염 표면항원(HBsAg)이 양성을 보이는 원발성간암 환자 38명을 대상으로 하였으며 HBV-DNA 중합효소연쇄반응법을 이용하여 정성적 검출 그리고 luminometry법을 이용하여 정량적 검출을 하였다. 결과 : HBV-DNA 중합효소연쇄반응법과 luminometry법의 양성율은 각각 57.9%, 39.5%를 보였다. 그리고 HBsAg과 HBeAg가 동시에 양성을 보인 11명에서는 HBV-DNA 양성율이 81.8%를 보였다. 결론: HBV-DNA 중합효소연쇄반응법의 양성율이 luminometry법에 의한 양성율보다 높은 결과를 보였고 HBV-DNA 검사는 B형 간염을 조기 발견하고 치료하여 만성간질환으로의 진행을 예방하고 특히 원발성간암의 병율을 낮추는데 많이 기여할 것으로 사료되었다. Background : Primary hepatocellular carcinoma(PHCC) is the most common malignant neoplasm in most countries of Asia and Africa. Hepatitis B virus is known to be strongly related to the pathogenesis of PHCC. HBV-DNA PCR and HBV-DNA quantitation assay were attempted to apply to 38 cases of HBsAg positive PHCC. Methods : The ordinary HBV markers(HBsAg, anti-HBs, anti-HBc(Ig-G and -M), HBeAg and anti-HBe) were examined with ELISA. Qualitative screening of HBV-DNA PCR and HBV-DNA quantitation-luminometric measurement were performed. Results : Among 38 cases of HBsAg positive PHCC, positive rates for HBV DNA-PCR and HBV DNA-quantitation were 57.9% and 39.5%, respectively. And 11 cases which were positive for both HBsAg and HBeAg showed 81.8% positive rate in HBV-DNA PCR. Conclusion : For 38 cases of HBsAg positive PHCC, the positive rate for HBV DNA-PCR was higher than HBV-DNA quantitation-luminometry. In HBV-DNA PCR, both HBsAg and HBeAg positive cases showed high positive rate.

The depressive patients can be divided into two subgroups by presence and absence of pain symptoms. Those without pain symptoms have blunted pain sensitivity whereas those with pain have normal range of pain sensitivity, and are clinically characterized by anxiety and irritability. The aim of the study is to test if these clinical profiles of the depressives with pain symptoms are related with reduced level of brain serotonin(5-HT). Forty four mice were randomly divided into two groups : one group to be bred with tryptophan free diet and the other with normal control diet, each for 4 weeks. Before the beginning of the breeding period, measured were locomotor activity by open field test, anxiety by elevated plus maze and nociceptive sensitivity by tail flick test, before and after forced swimming(FS). During each FS, duration of immobilization was also measured. The sable sets of measurements were repeated at the end of the breeding period. The brain 5-HT and 5-hydroxyindoleacetic acid(5-HIAA) were measured by high performance liquid chromatography. The results were as follows 1.Four weeks of tryptophan free diet reduced significantly body weight, brain weight, and levels of 5-HT and 5-HIAA in the whole brain. 2.Tryptophan depletion did not influence basal nociceptive sensitivity as measured by tail flick latency before FS. The normal blunting of the pain sensitivity induced by forced swimming was preserved in the tryptophan depleted group. 3.Tryptophan depletion did not influence general locomotor activity in open field. 4.Tryptophan depletion increased significantly time spent on the open arms at the elevated plus maze test done before FS. This anxiolytic-like effect was reduced by FS. 5.Tryptophan depletion did not influence duration of immobilization during FS. From these results, it is suggested that the genesis of the depression with pain symptoms is not medicated by quantitative reduction of brain serotonin

저자는 anti-prostaglandin의 화상독에 의한 간상해에 미치는 영향에 관하여 알아보고자 Sprague-Dawley계 흰쥐 수컷의 체표 30%에 3도 화상을 일으키고 생리식염수와 anti-prostaglandin제제인 flurbiprofen을 투여한 후 각각 5일과 10일 후 도살하여 간의 변화를 관찰하였으며 성적은 다음과 같다. 생리식염수를 투여한 실험군에서는 화상 5일 후 간세포에 mitochondria의 상해와 ER의 확장이 있었고 유동내에는 호중구 등 염증세포의 침윤이 있었다. 화상 10일 후에는 상기한 mitochondria의 상해가 거의 수복되고 ER의 확장도 감소되었으며 유동내의 염증세포도 거의 보이지 않았다. flurbiprofen을 투여한 실험군에서는 화상 5일후 mitochondria의 상해와 ER의 확장이 관찰되었으며 이는 화상 10일 후 까지 지속되었다. 이상의 성적으로 보아 중증화상후에 간은 화상독에 의하여 간세포 mitochondria의 상해를 주로하는 손상을 받게되나 이는 시간이 지나면 수복 가능한 가역적인 상해라 보아진다. 또한 anti-prostaglandin제제는 화상독에 의한 간세포상해에 거의 영향을 미치지 못할 것으로 생각된다. An ultrastructural study was carried out to investigate the effects of burn toxin to liver. Thermal burns wee tried on the skin of Sprague-Dawley rats with severity of 30% and 3rd degree. Flurbiprofen (a kind of anti-prostaglandin) and normal saline was administered every day after burn. The animals were sacrificed at 5 days and 10 days after burns and the livers were extracted for electron microscopic observation. The liver cells of saline intake groups at 5 days after burns were characterized by generalized mitochondrial injury, such as swelling, loss of cristae and membrase destruction. Dilatation of ER and lysosomal increase are also noted. The sinusoid revealed neutrophilic infiltration. At 10 days after burns the liver cells demonstrated nearly normal structure without mitochondrial injury. Mild dilatation of ER was seen. The flurbiprofen intake groups revealed that mitochondrial swelling, loss of critae and destruction of mitochondrial membrane with dilatation of ER and lysosomal increase at 5 days after burns. These features were continued to 10 days after burns. According to these results, it would be concluded that the effects of burn toxin to liver is characterized by mitochondrial injury and it is reversible change. And the anti-prostaglandin drugs may not be effective to inhibit the progressive injury induced by burn toxin.

김창학,곽중민,강정호,강인석 진주산업대학교 2000 산업과학기술연구소보 Vol.- No.7

A standardized construction information classification system is essential for organizing construction CALS and CM. In 1997, Uniclass system was developed for superseding CI/SfB system that was being used as a representative WBS. Uniclass system is organized on the basis of ISO frame and consists of tables for classifying information related to construction management and electronic commerce. This study was implemented for the analysis of applicability of Uniclass system, comparing with CI/SfB system, as a WBS for the construction CALS. This study suggests a alternative table of Uniclass to improve applicability in practical use. Uniclass system was analyzed as the best classification system for the civil engineering project among the existing systems, howewer, the classified items for CM and construction CALS need to be modified with more detailed items.

김응석,이정호,김중훈 대한상하수도학회 2003 상하수도학회지 Vol.17 No.2

In domestic sewer rehabilitation works, the numerical weighting based on number of sewer defect is used to determine the propriety of rehabilitation order. In case of the decision standard in each defect contents of inside and outside of the country, the weight for determining sewer rehabilitation order is composed of several distribution of marks, not considering the weight in each sewer defects. In this study, the fifteen defect contents are determined suitable for domestic situation based on the sewer defect data of inside and outside of the country. Also, we select persons in charge of the business to calculate the detail weight and pose questions about important level of each sewer defect contents. The results of using Delphi method which is a question survey method apply the AHP and calculate the weight in each sewer defect. The appropriate marks matrix of sixteen sewer defects is made for laying precise decision standard of sewer condition through the result of analysis. The marks matrix of sixteen sewer defects can solve the complicated decision making problems of sewer rehabilitation works.
