Jornal Brasileiro de Patologia e Medicina Laboratorial , 2003,
Abstract: O adenoma de células mucosas é uma neoplasia benigna rara que se origina nas glandulas da mucosa das vias aéreas maiores. A maioria dos casos é vista nos br nquios, mas já foram descritos casos na traquéia e nas vias respiratórias distais. O tumor é constituído por células mucossecretoras, que geralmente formam glandulas que crescem para dentro da luz, formando massa obstrutiva. N o há predile o por sexo ou idade. Nós relatamos aqui um caso observado em uma menina de 5 anos, o mais jovem relato na literatura consultada, que se apresentou no Hospital das Clínicas da Faculdade de Medicina de Ribeir o Preto para investiga o e tratamento de pneumonia recorrente e atelectasia do pulm o. O exame broncoscópico mostrou massa obstruindo o br nquio inferior esquerdo e a biópsia revelou les o benigna incaracterística. A remo o cirúrgica do segmento afetado, que é o tratamento recomendado para esta les o benigna, evidenciou um adenoma de células mucosas. A crian a recuperou-se bem e estava completamente livre de doen a quando deixou o seguimento com 6 anos de idade.

Abstract: the emulsion stability, composition, structure and rheology of four different commercial italian salad dressings manufactured with traditional and light formulations were evaluated. according to the results, the fat content ranged from 8% (w/w) (light) to 34% (w/w) (traditional), the carbohydrate concentration varied between 3.8% (w/w) (traditional) and 14.4% (w/w) (light) and the ph was between 3.6-3.9 for all samples. the microscopic and stability analyses showed that the only stable salad dressing was a light sample, which had the smallest droplet size when compared with the other samples. with respect to the rheological behaviour, all the salad dressings were characterized as thixotropic and shear thinning fluids. however, the stable dressing showed an overshoot at relatively low shear rates. this distinct rheological behavior being explained by the differences in its composition, particularly the presence of a maltodextrin network.
