1CD10在毛发上皮瘤和基底细胞癌中的表达显示文摘Background: Trichoepithelioma (TE) is a benign neoplasm that shares both clinical and histologic features with basal cell carcinoma (BCC). However, it is important to distinguish these neoplasms. Limited immunohistochemical stains are available to separate these two tumors. Methods: CD10 protein immunohistochemistry was performed on paraffin-embedded biopsies of 13 TE and 23 BCC diagnosed by routine microscopy. Cases were analyzed for pattern of CD10 expression by tumor cells and surrounding stroma. Results: Twelve of 13 (92% ) TE showed positive stromal immunoreactivity. Of these, eight cases also demonstrated positivity of the papilla, and two also showed positivity of the basaloid cells. No TE demonstrated epithelial expression alone. On the other hand, expression of CD10 by basaloid cells was identified in 20 (87% ) cases of BCC. Stromal positivity was also identified in three cases of BCC. Condensation of CD10-positive stromal cells around basaloid nests was statistically significant in differentiating TE from BCC (p < 0.0001). Conversely, CD10-positive basaloid cells were seen predominantly in BCC (p < 0.0001). Conclusions: This study demonstrates a statistically significant difference in CD10 staining pattern between TE and BCC. Thus, CD10 may be a useful adjunct marker in distinguishing these tumors.Pham T.T.N. Selim M.A. Burchette Jr. J.L. C. Herman 党倩丽 2006世界核心医学期刊文摘(皮肤病学分册)2006,0,5:2
2Dye removal using some surface modified silicate minerals显示文摘The objective of this work is to study the efficiency of some surface modified phyllosilicate minerals(bentonite and glauconite) in the removal of dyes from textile waste water. It is found that complete dye removal was achieved by using 10–25 g modified glauconite from solutions having a dye concentration of 10–50 mg/L. Adsorption data were modeled using Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherms. Adsorption capacities and optimum adsorption isotherms were predicted by linear regression method. The analysis of experimental isotherms showed that Langmuir isotherm reasonably fit the experimental data in the studied concentration range for the adsorption of dye onto glauconite mineral surface where Freundlich isotherm fit the experimental data for the adsorption of dye onto bentonite mineral surface.Selim K.A.
