1. 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

2. Crisotilas brasileiras : caracterização dos sitios superficiais por cromatografia inversa, microscopia de força atõmica e espectroscopia no infravermelho
Chrysotile, a fibrous serpentine, is an asbestos mineral with potential applications in many chemical areas. Although extensively studied, some aspects of the nature and properts of its surface sites are obscure, specially for the brazilian chrysotiles. ln this work we owe the characterization of the surface sites of brasilian chrysotile coming from the mine

3. Antagonistic activity of poly (4-vinylpyridine-N-oxide) to the inhibition of viral interferon induction by asbestos fibres.
The depressive activity of both serpentine (Canadian and Rhodesian chrysotiles) and amphibole (amosite, crocidolite, and anthophyllite) asbestos fibres on interferon induction by influenza virus was significantly diminished or abolished completely when either asbestos fibres or LLC-MK2 cell monolayers were pretreated with poly(4-vinylpyridine-N-oxide).

4. Correlation between fibre content of the lung and disease in east London asbestos factory workers.
The lungs from 36 past workers at an east London asbestos factory who had died from asbestos related disease were compared with lung tissue from 56 matched control patients being operated on in east London for carcinoma of the lung, correlating the severity of asbestosis and the presence of pulmonary carcinoma or mesothelioma of the pleura or peritoneum with
