Background: Recently there has been evidences that serum Lp(a), an independent risk factor to atherosclerotic cardiovascular diseases, were increased in proteinuric disorders such as nephrotic syndrome and diabetic nephropathy. Methods: We intended to search of altered concentrations of Lp(a) in proteinuric disorder measuring serum Lp(a) concentrations with ELISA in 44 glomerulonephritic patients(25 nephrotic syndrome(NS), 19 non-nephrotic range proteinuric glomerulonephritis(GN), 25 diabetic nephropathy patients(DN), and 31 healthy controls(HC). Also, we compared Lp(a) concentration between glomerulonephritis patients and diabetic nephropathy patients with proteinuria of similar degree. Results: 1) There were significantly increased levels of total choesterol, triglyceride, and LDL-cholesterol in Ns compared to GN, DN, HC. 2) There were significantly increased concentrations of serum Lp(a) in NS compared to HC, but no signiicant difference in serum Lp(a) among NS, GN, and DN. 3) There was no significant difference in serum Lp(a) concentrations between NS & DN with 24 hour urine protein greater than 3.0g. 4) There was no significant difference in serum Lp(a) concentration between GN with 24 hour urine protein greater than 0.5g and less than 1.5g and DN with proteinuria of simial degree. 5) In glomerulonephritis patients, there was negative correlation between serum Lp(a) concentration and serum albumin level but correlation with 24 hour urinary protein, total cholesterol, Ldl-cholesterol, and HDL-cholesterol was not shown. In diabetic nephropathy, there was no significant correlation among serum Lp(a) concentration and all parameters including serum albumin, 24 hour urinary protein, and other lipid profiles. Conclusion: The present study confirmed that patients with nephrotic syndrome of diverse etiologies have makedly increased plasma level of Lp(a), in conjunction with other lipid abnormalities. However, this study shows no difference in Lp(a) concentrations between diabetic nephropathy and glomerulonephritis with similar degree of proteinuria.

This study was to evaluate the filtration performance of metal membrane with synthetic wastewater and to investigate the effective control of membrane fouling using ozone backwashing. The increase of substrate concentration caused the increase of cake layer resistance and total resistance, however, plugging resistance decreased. Total resistance of metal membrane was mainly attributed to the permeate resistance of cake layer, which was formed by deposited particles from the physico-chemical interactions of solids on membrane surface. Intermittent ozone backwashing was more effective then the air backwashing for fouling reduction. The permeation flux recovery of air backwashing decreased over 50%, however, ozone backwashing decreased less than 10% for 4 hours filtration. This may be ascribed to the degradation of foulants in pore structure by the strong oxidation of ozone and physical exfoliation of cake layer on membrane surface with backwashing.

We developed an algorithm that effectively extracts slicing points from STL 3D models for a new RP system which can fabricate various materials. Since an STL file has a simple data structure and contains much embiguity, we considered all the cases between facet positions and slicing planes for effective slice extraction from the STL file, and reduced the overall processing time. The effectiveness and efficiency of the proposed slicing method was tested by many STL 3D samples.

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.

Allergic contact dermatitis to topical corticosteroids seems to occur more frequently than previously supposed. But it is not easily recognized because the allergic condition for which the steroid is mostly prescribed masks the sensitization. Moreover, corticosteroids evoke some anti-inflammatory effect, even in case of steroid hypersensitivity. A 40-year-old man visited our department for the evaluation of aggravated skin lesion of trunk. Previously he was treated with Dermovate?? and Eumovate?? ointment for chronic dermatitis. He was patch tested to the Korean standard series, with Dermovate?? and Eumovate?? ointment as is. Patch test showed positive reactions to both ointments.(Korean J Dermatol 2003;41(10) : 1385~1389)

In Korea, angiodysplasia has not been reported until now. We experienced a patient with angiodysplasia in acute massive lower gastrointestinal bleeding. A 62-year-old male patient was admitted to the hospital because of hematochezia. No abnormality was found on gastrofiberscopy, colon barium study, and colonoscopy, but anemia persisted despite transfusion. By selective angiography, multiple tortuous vascular tangles were identified in the cecal area in the later arterial phase. Awareness of angiodysplasia in acute massive lower gastrointestinal beding is needed.
