산 처리한 순환골재를 사용한 순환골재 콘크리트의 강도특성에 관한 연구
이규석,김용재,박제영,성병길,박철우,심종성 한국구조물진단유지관리학회 2011 한국구조물진단학회 학술발표회논문집 Vol.2011 No.9
This study is intended to assess the usability of recycled aggregate which is produced by wastes-concrete. It analyzes the quality of the recycled aggregate which is produced through the acid treatment process. The conclusions of the study are as follows. The absorption and the specific gravity of acid treated aggregates (both fine and coarse) was found much better than the ordinary recycled aggregates. The concrete made by incorporating acid treated aggregates exhibited higher compressive strength at all ages as compared to the concrete produced by using ordinary recycled aggregates.

Scleroderma is a connective tissue disease characterized by excessive accumulation of collagen in skin and visceral organs due to increased collagen production by scleroderma fibroblasts. The basic etiology of this collagen accumulation is not known. We examined the expression of various extracellular matrix genes in cultured fibrolasts using Northern blot and slot-blot hybridization. The scleroderma fibroblasts exhibited characteristic mRNA size of extracellular matrix genes and prominanty increased type I and III procollagen mRNAs levels compared to control fibroblasts cultures from univolved skin. The ratios of type I /IE procollagen in scleroderma cell lines were not so much different to the controls. These results indicate that increases of collagen biosynthesis in scleroderma can be a accounted for, at least in part, by an increased content of transcriptable type I and type JE procollagen mRNAs, both.

피부 섬유아세포의 IV형 교원질 및 Laminin 유전자 발현

Basement membrane zone gene expression by fibroblast cultures was examined by molecular hybridizations with human sequence specific cDNAs corresponding to type 1V procollagen and laminin subunit polypeptides. Northern transfer analysis with total RNA revealed the presence of specific mRNA transcripts for al (IV) and a2 (1V) chains of type 1V procollagen as well as Bl and B2 chains of laminin. Laminin A chain mRNAs were not detected using the same RNA preparations. The molecular size of al (1V) and a2 (1V) procollagen mRNA revealed 6.8kb and 6.7kb, respectively. The molecular size of Bl chain of laminin revealed 5.6kb, and B2 chain revealed 8.2 and 5.5kb polymorphic transcripts. In slotblot analysis using densitometer, steady-state levels of type IV procollagen and laminin mRNAs indicated that they were in relatively low abunclance, as compaired with type I procollagen mRNA. Quantitative levels of al (IV) and laminin Bl chaii mRNAs were more abundant than those of a2 (IV) and laminin B2 mRNAs. The mRNA ratio of al (IV)/a2 (lV) and laminin Bl/B2 were 1.9 and 1.5, respectively. These results demonstrate evidence for differential regulation of the expression of different basement membrane zone molecules during the formation of basement membrane.
