The purpose of this study was to elucidate whether the molecular defect of acid-base transporters in renal tubules is related to the functional defect of urinary acidification in distal renal tubular acidosis(RTA). We performed NH₄Cl, furosemide, or bicarbonate loading test to evaluate renal acidification function, and immunohistochemistry using antibodies to H^+ -ATPase, Cl^-/HCO₃^- exchanger(band-3 protein), and Na^+/K^+ -ATPase in kidney tissue in 6 patients with RTA and renal cell carcinoma patients as normal controls. Kidney tissue was obtained either by percutaneous needle biopsy(RTA) or nephrectomy(NC). The results were as follows; 1) In all six RTA patients, proton secretory defect of distal acidification was shown by a failure to lower the urine pH after NHC1 loading or furosemide test or abnormally low urine-blood pCO₂ difference during bicarbonate loading. In two patients with RTA, proximal acidification defect was combined, which was demonstrated by increased fractional excretion of bicarbonate. 2) In mal control, intense H^+ -ATPase and band-3 protein staining was observed in collecting ducts. 3) In distal RTA patients, H6+ -ATPase and band-3 protein staining was not demonstrable or markedly decreased in the intercalated cells of distal nephron. 4) In two patients who had both proximal and distal RTA, H^+ -ATPase staining was markedly decreased in the brush border of proximal tubules as well as the distal nephron. In conclusion, the defect of acid-base transporters in renal tubule was related with the functional defect of urinary acidification in distal RTA.

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>Atopic dermatitis (AD) is a highly pruritic, chronic inflammatory skin disease associated with hyperreactivity to environmental triggers. Among those, outdoor air pollutants such as particulate matter (PM) have been reported to aggravate pre-existing AD. However, underlying mechanisms of air pollution-induced aggravation of AD have hardly been studied.</P> <P><B>Objective</B></P> <P>To investigate the molecular mechanisms by which glyoxal, a PM-forming organic compound, exacerbates the symptoms of AD induced by neonatal capsaicin treatment.</P> <P><B>Methods</B></P> <P>Naïve and AD rats had been exposed to either fresh air or vaporized glyoxal for 5 weeks (2 h/day and 5 days/week) since one week of age. Pruritus and dermatitis were measured every week. The skin and blood were collected and immunological traits such as Staphylococcus aureus skin colonization, production of antimicrobial peptides and immunoglobulin, and mRNA expression of inflammatory cytokines were analyzed.</P> <P><B>Results</B></P> <P>Exposure to glyoxal aggravated pruritus and dermatitis in AD rats, but did not induce any symptoms in naïve rats. Staphylococcus aureus skin colonization was increased in the skin of both naïve and AD rats. Expression of antimicrobial peptides such as LL-37 and β-defensin-2 was also increased by exposure to glyoxal in the skin of both naïve and AD rats. The mRNA expression of Th1-related cytokines was elevated on exposure to glyoxal. However, serum immunoglobulin production was not significantly changed by exposure to glyoxal.</P> <P><B>Conclusion</B></P> <P>In AD rats, exposure to glyoxal exacerbated pruritus and cutaneous inflammation, which was associated with increased colonization of <I>S. aureus</I> and subsequent immunological alterations in the skin.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Exposure to glyoxal aggravated the symptoms in AD rats, but did not induce AD in naïve rats. </LI> <LI> <I>S. aureus</I> skin colonization and subsequent expression of antimicrobial peptides were increased after exposure to glyoxal. </LI> <LI> Exposure to glyoxal elevated the production of Th1-related cytokines such as TNF-α and IFN-γ in the AD lesional skin. </LI> </UL> </P>

Today, the interest for the quality of life is highly concerned for people especially who lives in a city, and the demand for cultural life and the need for open space as a cultural landscape are naturally increased. The purpose of this study is to provide the actual conditions and problems of small lots in a theater as a open space, and to propose the basic resource for planning and renovating them. The result of this study shows that users were unsatisfied with accessibility, safety, noise, pollution, green areas, facilities and programs in small lots. Also it shows that the important factors to design small lots in a theater are the location, accessibility, safety, form and area. Moreover, it is concentrated on cultural facilities and programs as totally considerable factors to plan and reactivate small lots in a theater.

자궁경부암 선별검진을 위한 PapSure 검사에서 Spiral Brush의 유용성에 관한 연구

송언호,김어진,명나혜,박충학 대한부인종양 콜포스코피학회 2002 Journal of Gynecologic Oncology Vol.13 No.4

2001년 12월 1일부터 2002년 6월 30일까지 만 7개월 간 단국대학교의료원 산부인과 부인종양 Clinic에서 자궁경부암 선별검진을 위한 PapSure 검사를 시행한 환자 중 SpiraBrush Cx_® 검사를 실시한 33예를 대상으로 하여, 기존의 Papanicolaou 세포진 검사의 진단과 SPiraBrush Cx_®)에 의한 Papanicolaou 세포진 검사의 진단 및 최종적인 병리조직학적 진단을 비교, 분석하여 SpiraBrush Cx_®에 의한 세포진 검사가 생검에 의한 조직검사를 대체할만한 유용성이 있는지 그 여부를 조사하기 위하여 본 연구를 시행하여 다음과 같은 결과를 얻었다. 1. 환자의 연령별 분포는 21세에서 70세까지였으며 40-49세 군이 42%로 가장 많은 분포를 보였고, 평균 연령은 45.7세였다. 2. 환자의 평균 임신횟수는 3.6회였으며, 평균 출산횟수는 2.0회였다. 3. 기존의 자궁경부 세포진 검사(Conventional Papanicolaou cytology)상 진단이 음성으로 나온 경우가 19예(57.6%)였고, ASC를 포함하여 양성으로 나온 경우가 14예(42.4%)였다. 자궁경부 형광경진 검사(Speculoscopy)에서는 음성이 13예(39.4%)였고, Suspicious 진단을 포함하여 양성으로 나온 경우가 20예(60.6%)였다. SpiraBrush Cx®에 의한 세포진 검사(SpiraBrush Cx_® Papanicolaou cytology)에서는 진단이 음성인 경우가 8예(24.2%)였고, ASC를 포함하여 양성으로 나온 경우가 25예(75.8%)였다. 4. 병리조직학적 검사의 진단은 음성 12예(52.2%), 저등급 편평상피내병변(Low-grade Squamous Intraepithelial Lesion: 이하 LSIL이라 함) 2예(8.7%), 고등급 편평상피내병변(High-grade Squamous Intraepithelial lesoin: 이하 HSIL이라 함) 3예(13.0%), 편평세포암(Squamous Cell Carcinoma: 이하 SCC라 함) 6예(26.1%)였다. 5. 검사 결과의 양성판정 기준을 세포진 검사의 경우는 ASC 이상으로 하고 조직학적 검사의 경우는 LSIL이상으로 정할 경우, 기존의 Papanicolaou 세포진 검사의 민감도는 63.6%이고 특이도는 66.7%였으며, SpiraBrush Cx_®세포진 검사의 민감도는 90.9%이고 특이도는 33.3%였다. 이상의 결과로 미루어 볼 때 연구 대상의 숫자가 적어서 통계학적인 유의성은 찾을 수 없으나 SpiraBrush Cx_®가 자궁경부암 선별검진에서 생검에 의한 자궁경부의 조직학적 진단을 대체하지는 않는다고 판단된다. 그러나 기존의 Papanicolaou 세포진 검사의 민감도가 63.6%인데 반하여 SpiraBrush Cx_® 세포진 검사의 민감도는 90.9%로 훨씬 더 높았으며 이로 인해 SpiraBrush Cx_® 세포진 검사의 특이도는 33.3%로 훨씬 낮았는데 이는 매우 흥미있는 사실로서 향후 많은 Data로 더욱 연구하여 진위를 구분함이 필요하리라 사료된다. 또한 본 연구에서는 SpiraBrush Cx_® 기구의 강모들이 단단하고 날카로워서 기저막층까지의 조직과 상피층 세포들을 탈락시키면서 많은 출혈을 초래하여 슬라이드 판독에 어려움을 주었고 이는 연구 결과에 지대한 영향을 미쳤으리라고 생각되는 바, 이러한 출혈로 인한 요인을 최대한 배제하기 위하며 향후 SpiraBrush Cx_® 세포를 채취한 후 최신의 자궁경부 세포진 검사법인 ThinPrep Pap Test를 이용하거나 조직표본을 만들기 위한 Cellblock 기법을 사용하여야 한다고 판단된다. Objective : The purpose of this study was to investigate the clinical efficacy of a new stiff bristled spiral shaped brush (SpiraBrush Cx_(??))∼in) PapSure Test for cervical cancer screening, by comparing SpiraBrush Cx_(??) cytologic diagnoses with conventional Papanicolaou cytologic diagnoses and final histologic diagnoses. Methods : This study was performed in Gynecologic Oncology Clinic of Department of Obstetrics and Gynecology at Dankook University Medical Center from December I, 2001 to June 30, 2002. Thirty three cases who underwent PapSure Test (Pap cytology t Speculoscopy) were analyzed. SpiraBrush Cx_(??) Papanicolaou cytologic diagnoses were compared with conventional Papanicolaou cytologic diagnoses and histologic diagnoses as a reference standard. Results : Followings are the results summarized. 1. Age distribution was between 21 and 70. The mean age was 45.7 years. 2. The mean gravidity was 3.6 and the mean parity was 2.0. 3. There were 19 (57.6%) conventional Papanicolaou cytologic diagnoses of Negative, and 14 (42.4%) of Positive including ASC. There were 13 (39.4%) Speculoscopy diagnoses of Negative, and 20 (60.6%) of Positive including Suspicious. There were 8 (24.2%) SpiraBrush Cx_(??) cytologic diagnoses of Negative and 25 (75.8%) of Positive including ASC. 4. There were 12 (52.2%) histologic diagnoses of Negative, 2 (8.7%) of LSIL, 3 (13.0%) of HSIL, and 6 (26.1%) of SCC, according to the criteria of TBS, 2001. 5. For detecting LSIL or worse lesions, conventional Papanicolaou cytologic test yielded sensitivity of 63.6% and specificity of 66.7%. On the other hand, SpiraBrush Cx_(??) cytologic test yielded sensitivity of 90.9% and specificity of 33.3%. Conclusion : SpiraBrush Cx_(??) cytologic diagnosis does not seem to have clinical efficacy replacing the histologic diagnosis by punch biopsy in cervical cancer screening in this study. But further studies using ThinPrep Pap Test or Cellblock techniques with large data will be required and anticipated.
