Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

Objective: Several factors contribute to the development of hypertension in patients with IgA nephropathy (IgAN). This study was conducted to find the relationships between baseline blood pressure (BP) and clinico-pathological findings in patients with IgAN and normal renal function. Design and Method: Clinico-pathological findings were analyzed in a total of 163 patients with IgAN and serum creatinine ￡ 1.1 mg/dL from The Kyung-Hee Cohort of Glomerulonephritis. The glomerular surface area (GSA) was determined using imaging analysis software. The serum and urine angiotensinogen (AGT) concentrations were measured using human ELISA kits.?Results: Mean serum creatinine concentration was 0.86 (0.5~1.1) mg/dL. Systolic BP was ≥ 130 mmHg in 72 patients (44%) and ≥ 140 mmHg in 42 (26%). Patients with systolic BP ≥ 130 mmHg as compared with those <130 mmHg had higher GSA and tubulointerstitial fibrosis and showed worse follow-up clinical findings: higher concentrations of serum creatinine, larger amount of proteinuria and lower levels of GFR. Systolic BP was positively correlated with age, baseline and follow-up proteinuria, serum uric acid concentrations and IgM deposit and negatively with follow-up GFR and the slope of change in 1/serum creatinine for 2 years, while it has no significant relationships with serum and urine AGT and 24 hour urinary sodium excretion. Conclusions: This study showed that systolic BP was associated with renal progression and pathological findings, glomerulomegaly and tubulointerstitial fibrosis, in patients with IgAN.

( Hyung Oh Kim ),( Chun Gyoo Ihm ),( Tae Won Lee ),( Kyung Hwan Jeong ),( Seul Ki Kim ),( Ji Yun Park ),( Jin Sug Kim ) 대한내과학회 2014 대한내과학회 추계학술대회 Vol.2014 No.1

Background: We report a rare case of CAPD peritonitis caused by Ochrobacterium anthropi. Introductions: Among the continuous ambulatory peritoneal dialysis(CAPD) patients, peritonitis is one of the most commonly taken complications, and also the general cause of dialytic modality exchange to hemodialysis. Usual pathogens of CAPD peritonitis may be bacteria, fungi, mycobacteria. Coagulase negative staphylococci, S. aureus, campylobacter, pseudomonas are common reported pathogens among the bacteria, of CAPD peritonitis cases, meanwhile candida is among fungi. Ochrobacterium anthropi is one species of Brucellaceae, which is rare pathogen of human disease. Case (Methods and results): 73 years old female, who was on CAPD due to diabetic end stage renal disease visited Kyung-Hee University hospital with intermittent abdominal pain. Body fi uid analysis showed increased white blood cell(WBC) count of 26,750/mm3 with her peritoneal fi uid. Culture study with peritoneal fi uid suggested O. anthropi, and DNA sequencing with PCR was consistent with O. anthropi. Intraperitoneal ceftazidime and cefazolin were administrated as empirical antibiotics. Ceftazidime resistance was noted with the result of antibiotics sensitivity test at 7th day of hospitalization, and antibiotics were changed into intraperitoneal gentamicin, which showed sensitivity to the pathogen. CAPD catheter removal and antibiotics re-exchange into imipenem and cefazolin, which were other sensitive antibiotics by the sensitivity test, were done since clinical manifestation and peritoneal fi uid WBC count was repeatedly improved and aggravated. The patient discharged with improved lab test results and resolving clinical symptoms afterward. Conclusions: We presentators report rare case of CAPD peritonitis with pathogen of O. anthropi. The pathogen of the case confi rmed by classical microbiologic, and molecular biologic Methods: The patient was unable to treat only with antibiotics, thus CAPD catheter, which might be act as colonizing source, was removed, and the disease resolved.

정신분열증 환자의 지각결핍을 타 질환군과 비교해 보기 위하여 1983.6.1부터 동년 8월 31일 까지 전남의 대병원 정신과 외래에 다니는 우울증 환자 20명 국립나주정신병원에 입원한 정신분열증 환자 20명을 임의 선택하여 Garner의 모형을 이용 카드 분류를 시행하고 그 자료를 토대로 수정분류시간, 공제지수, 비율지수 등을 산출하여 변량분석한 결과 다음과 같은 결론을 얻었다. 1. 양 군의 수정시간을 변량 분석한 결과 유의한 차이를 발견할 수 없었다. 2. 공제지수와 비율지수를 변량분석한 결과 과다성 분류와 여과분류에서는 공제지수와 비율지수에서 아무런 유의차가 없었다. 3. 주사분류에서는 공제지수 비교에서 1% 수준에서 비율지수 비교에서 5% 수준으로 우울증의 분류시간이 긴 것으로 나타났다. 이상의 결과를 살펴볼 때 여과기능의 결함이라는 지각결핍은 정신분열증의 고유한 장애가 아닐 수도 있겠다. The perception of stimuli with two dimensions (size and figure) was investigated using Garners card sorting method into schizophrenic and depressive patients. The comparison of three performance indices (redundancy, filltering, scanning) between two study groups revealed that 1) the analysis of variance of the corrected time shows no significant difference between two groups, 2) in redundancy and filtering sorting the subtractive and ratio indices show no significant difference between two groups, 3) in scanning sorting the depressive group shows significantly longer sorting time than schizophrenic group(p<0.01 in subtractive index, p>0.05 in ratio index). The above findings suggest that the previously known perceptual deficit(mainly filtering deficit) may not be specific only to schizophrenia.

Objective : Periapical cyst is a relatively common disease but heterogenous in histogenesis, and inflammatory reaction and fibrosis of varying degree are associated in the cystic wall. The aim of thes study is to evaluate the clinico-pathologic characteristics such as patient's age, ses, location, and the degree of inflammatory reaction and fibrosis of periapical cyst and the role of TGF-α and TGF-β cytokines in the inflammed periapical cyst. Methods and Material : The materials were 43 cases of periapical cyst and clinical information with age, sex, location(maxilla vs mandible, right vs left, region involved) were recorded. Histopathological examination on the degree of inflammatory reaction and fibrosis and immunohistochemical stining for TGF-α and TGF-β were perfomed. Satistical analyses between clinical parameters, the degree of inflammation and fibrosis and expressions for TGF-α and TGF-β were followed. Results : 1. Thirt(69.8%) of 43 cases were older than 20 year-old. and no significant differences of incidence according to patient's sex was noted. In 25(58.1%) out of 43 case. 20(54.1%) out of 37 cases, and 20(48.8%) of 41cases, the cyst was located on the maxilla. in right side and in premolar region respectively. 2. The cysts of developmental and inflammatory origin were 24(55.8%) and 19(44.2%) of 43 cases, respectively and there were no siginificant differences of patient's age, sex, and location of cysts according to the origin of cysts. 3. Fibrosis was more conspicuous in cases older than 20 year-old. (p=0.0179), but no significant difference in the degree of inflammatory reaction according to patient's age and in the degree of inflammatory reaction and fibrosis according to sex and location of the cysts were seen. 4. Inflammatory reaction was slightly more in cysts of inflammatory origin, but no significant defferences in degree of inflammation and fibrosis according to origin of the cysts. 5. The degree of inflammatory reaction and TGF-α and TGF-β expressions showed a tendency of positive correlation(p=0.1563), but there were no statistically significant relationships between the degree of inflammation and fibrosis and TGF-α and TGF-β expressions. 6. In the cysts of developmental origin, TGF-α expression in the epithelial cells was significantly increased than inflammatory origin, but TGF-α and TGF-β expressions in the inflammatory cells and stromal cells showed no significant difference according to the origin Conclusion : The degree of inflammatory reaction and fibrosis of periapical cysts was different according to patient's age and location of the cyst. TGF-α and TGF-β cystokines seemed to be involved in the inflammatory reaction and fibrosis of periapical cyst, however, TGF-α and TGF-β expressions was not parallel to the degree of inflammatory reaction and fibrosis. These results suggest that other cytokines in addition to TGF-α and TGF-β may also be involved in the inflammatory reaction and fibrosis of periapical cyst. Increased TGF-expression in the epithelial cells of the cysts of developmental origin could be a helpful finding to defferentiate the origin of the periapical cyst.

Calcium concentration in the bone resorption lacunae is high and is in the mM concentration range. Both osteoblast and osteoclast have calcium sensing receptor in the cell surface, suggesting the regulatory role of high extracellular calcium in bone merabolism. In vitro, high extracellular calcium stimulated osteoclastogenesis in coculture of mouse osteoblasts and bone marrow cells. Therefore we examined the genes that were commonly regulated by both high extracellular calcium and 1,25(OH)_(2)vitaminD_(3)(VD3) by using mouse oligo 11 K gene chip. In the presence of 10 mM[Ca^(2+)]e or 10 nM VD3, mouse calvarial osteoblasts and bone marrow cells were co-cultured for 4 days when tartrate resistant acid phosphatase-positive multinucleated cells start to appear. Of 11,000 genes examined, the genes commonly regulated both by high extracellular calcium and by VD3 were as follows; 1) the expressions of genes which were osteoclast differentiation markers or were associated with osteoclastogenesis were up-regulated both by high extracellular calcium and by VD3; trap, mmp9, car2, ctsk, ckb, atp6b2, tm7sf4, rab7, 2) several chemokine and chemokine receptor genes such as sdf1, scya2, scyb5, scya6, scya8, scya9, and ccr1 were up-regulated both by high ectracellular calcium and by VD3, 3) the genes such as mmp1b, mmp3 and c3 which possibly stimulate bone resorption by osteoclast, were commonly up-regulated, 4) the gene such as c1q and msr2 which were related with macrophage function, were commonly down-regulated, 5) the genes which possibly stimulate osteoblast differentiation and/or mineralization of extracellular matrix, were commonly down-regulated;slc8a1, admr, plod2, lox, fosb, 6) the genes which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were commonly up-regulated;s100a4, npr3, mme, 7) the genes such as calponin 1 and tgfbi which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were up-regulated by high extracelluar calcium but were down-regulated by VD3. These results suggest that in coculture condition, both high extracellular calcium and VD3 commonly induce osteoclastogenesis but suppress osteoblast differentiation/mineralization by regulating the expression of related genes.

붙박이장은 일반적인 가구형태의 ``장(欌)``이 공간과 일체화 되어 보다 융통성 있는 활용이 가능하게 한 가구의 형태이다. 기존의 가구를 숨김으로써 그만큼의 손실된 공간이 확보되고 이어서 추가되는 공간 활용의 가능성이 뒤따르는 이점이 있으며 성립 조건이 까다롭지 않아 다양한 주거형태에서 나타난다. 고전적인 붙박이장의 형태는 조선시대에 다수 발견되며, 처한 환경과 방식에 따라 다양함과 오묘함을 띠고 있다. 이는 직선 목부재의 수직·수평결구에서 비롯된 전통건축방식을 기반으로 비움과 채움의 풍부한 공간변화에서 발전되어 온 산물이라 말할 수 있다. 안동을 비롯한 경북지역은 조선시대 상류고택의 융성지로 문중과 상류계층의 거주 체계와 격조 있는 건축적 요소들을 갖추어 전통건축 연구에 적합한 토양을 이루었다. 안채와 사랑채의 뚜렷한 위계와 환경적 요소로 인한 다양한 가옥형태는 다수의 붙박이 공간의 발견으로 이어졌다. 개괄적 측면으로 대상가옥 배치평면의 분석과, 세부적 측면으로 수납공간이 위치한 실내입면의 관찰을 통하여 다수의 사례들이 일련의 유형을 보임을 알 수 있었다. 추출되어 규명한 붙박이 공간의 전통문화 요소는 당시 삶을 살던 상류계층의 삶의 행태와 문화적 가치를 밝혀나가는 데 중요한 역할을 할 것이다. Built-in closets are ordinary closets merged within walls, making a more flexible use of the room space. By hiding the furniture the room gains that much more space and this enables to make flexible use of the additional space. It is not difficult to implement built-in closets, so they appear in many different styles of houses. Traditional built-in closets are frequently found in Chosun era`s housings, being diverse and mysterious according to the environment they are in. This is a developed product of the abundant space change of solid and void. It is based on the traditional architecture which derived from the usage of straight timber on the traditional cross-connections of the housings. The Kyung-buk region, including Ahn-dong, was a prosperous upper class area. It provided suitable soil for studies of traditional housings and the living style of the noble. The various housing styles, which were derived from environmental elements and the distinct hierarchy of the ahn-chae and the sarang-chae, developed into a range of discoveries of built-in closets. It was able to find a similarity in numerous different housings through the analysis of the layout and floor planning in a general sense, and the examination of the interior storage space in a more specific sense. The extracted and defined traditional elements of built-in closets will play an important role in identifying the life style of the upper class and its cultural value.

콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.
