13. Avaliação dos efeitos pulmonares e sistêmicos agudos em resposta à injeção intrapleural de talco de diferentes tamanhos de partículas / Pulmonary and systemic response following intrapleural instillation of talc with different particle size
Pacientes com comprometimento pleural por neoplasias malignas freqüentemente apresentam derrame pleural recidivante. Nestes casos, a sínfise das membranas pleurais (pleurodese) com a finalidade de evitar o acúmulo de líquido no espaço pleural deve ser considerada. O talco é o agente mais utilizado indicado para essa finalidade. Entretanto, seu uso tera

14. Resposta comparativa pleural "in vivo" e do mesotélio "in vitro" à exposição por diferentes fibras de asbesto / Comparison of in vivo pleural response and in vitro mesothelial response to different asbestos fibers
Asbestos-derived products are used thoroughly by industry. Several diseases related to asbestos exposition have been described, among them the primary tumor of the pleura mesothelioma. The mechanisms by which asbestos fibers produce injury to the pleural space are not clear. Among the factors possibly implicated are the effects secondary to an inflammatory r

15. Mecanismos de formação papel dos corpúsculos lipídicos nos eosinófilos na resposta inflamatória alergica / Mechanisms of fomatiom of the Paper of the Lipid Bodies in Eosinophils in the allergic inflammatory response
Lipid bodies are lipid-rich cytoplasmic inclusions, which are candidates to play a major role in the formation of eicosanoid mediators during inflammatory response. Lipid body formation/function in vivo at sites of allergic inflammation were never investigated. Here, we studied lipid body formation in vivo within eosinophils recruited to sites of allergic in

16. Estudo de ß-glucanas extraídas dos fungos Geastrum saccatum e Polyporos dermoporus: características químicas e atividades biológicas
Polissacarídeos de fungos têm recebido grande atenção devido ao seu uso potencial numa grande variedade de indústrias. Vários estudos têm demonstrado que polissacarídeos extraídos de basidiomicetos têm apresentado propriedades significantes como anti-inflamatório, antimicrobial , antioxidante e anti-tumoral. Apesar dessas propriedades potenciais,

17. Estudo comparativo de carragenanas comerciais Kappa, Iota e Lambda no processo inflamatório em ratos :edema intraplantar e pleurisia
As carragenanas comerciais Iota, Kappa e Lambda são raramente puras e, normalmente, apresentam vários outros tipos de polímeros. A quantidade exata de impurezas depende do método de extração e da alga utilizada. Logo, diferentes métodos têm sido utilizados para a determinação do conteúdo das carragenanas, tento em vista que elas são extensivament

18. Pleurisia e edema de pulmão induzidos por palications
The surface of endothelial cells is covered by negatively charged microdomains. The presence of cationic substances, for example polycations, in contact with rat skin, peritoneum and paw initiates an inflammatory process characterized by the infiltration of leukocytes and an increase in local permeability. In this work, the effect ofpolycations (poly-L-argin

19. Pleural fluid ferritin concentrations in human disease.
The concentration of ferritin was measured in the pleural fluid of 108 patients with pleural effusions. In all groups of patients the ferritin concentration was higher in pleural fluid than in serum. The greatest differences, with up to 100 times more ferritin in the pleural fluid, were found for patients with rheumatoid pleurisy, malignant effusions, and em

20. Quantitation in inflammatory pleural disease to distinguish tuberculous and paramalignant from chronic non-specific pleuritis.
AIM: To determine by morphometry if pleural biopsies with the histopathological diagnosis of "non-specific pleuritis", malignant, and tuberculous disease could be distinguished morphologically from those with truly non-specific disease. METHODS: Each pleural biopsy was reviewed taking into account three compartments of reference: the visceral/parietal mesoth

21. Comparison of the Tru-cut biopsy needle with the Abrams punch for pleural biopsy.
In a prospective study pleural biopsy specimens obtained with a Tru-cut needle were compared with those obtained with an Abrams pleural biopsy punch from 36 patients in Zimbabwe judged to have an effusion of at least 1.5 litres; one patient had two biopsies. Both instruments were used on each patient, the Abrams punch being followed by the Tru-cut needle. Th

22. Evidence of a role for mesothelial cell-derived interleukin 8 in the pathogenesis of asbestos-induced pleurisy in rabbits.
Although acute asbestos-induced pleurisy is characterized by an influx of neutrophils, the identity of the factors that attract these cells to the pleural space and the source of the factors are unknown. We found that instillation of crocidolite asbestos into the pleural space of rabbits led to the appearance in pleural liquid of chemotactic activity for neu

23. Acute local inflammation alters synthesis, distribution, and catabolism of third component of complement (C3) in rabbits.
In order to evaluate the basis for changes in plasma concentrations of the third component of complement (C3) during inflammation, we injected purified radiolabeled C3 into normal New Zealand White rabbits and into rabbits with turpentine-induced pleurisy. In the normal animals, C3 was distributed between the intravascular compartment (75%) and the extravasc

24. Transcription Factor Nrf2 Regulates Inflammation by Mediating the Effect of 15-Deoxy-Δ12,14-Prostaglandin J2
Activated macrophages express high levels of Nrf2, a transcription factor that positively regulates the gene expression of antioxidant and detoxication enzymes. In this study, we examined how Nrf2 contributes to the anti-inflammatory process. As a model system of acute inflammation, we administered carrageenan to induce pleurisy and found that in Nrf2-defici
