Asbestos fibers and interleukin-1 upregulate the formation of reactive nitrogen species in rat pleural mesothelial cells
…polymerase chain reaction (RT-PCR), increased progressively from 2 to 12 h in IL-1beta-containing cultures. Nitrite (NO2-), the stable oxidation product of .NO in mesothelial cell conditioned medium, was assayed through the Griess reaction…

A novel biotinylated probe specific for hyaluronate. Its diagnostic value in diffuse malignant mesothelioma
…staining for hyaluronate. Furthermore, the staining reaction was classed as moderate or greater in 26 mesotheliomas (79%), thus suggesting the utility of this probe in the differential diagnosis of malignant mesothelioma versus adenocarcinoma. We conclude that…

Asbestos fibers and interferon-gamma up-regulate nitric oxide production in rat alveolar macrophages
…in macrophage conditioned medium, was assayed by the Griess reaction. Production of NO2- by AM was significantly increased by both chrysotile (P < 0.01) and crocidolite (P < 0.05) asbestos fibers (10 micrograms/ml…

Pleural macrophage recruitment and activation in asbestos-induced pleural injury
…by scanning electron microscopy. Pleural macrophage supernatants were assayed for production of nitric oxide (NO) (by the Griess reaction) and tumor necrosis factor alpha (TNF-alpha) (by an enzyme-linked immunosorbent assay method). Significantly greater amounts…

Contribution of reactive oxygen and nitrogen species to particulate-induced lung injury
…reactive oxygen species (superoxide anion, hydrogen peroxide, hydroxyl radical formed through Fenton/Haber-Weiss reactions) and of reactive nitrogen species, in which nitric oxide reacts with superoxide to form peroxynitrite, an oxidant that nitrates tyrosine residues…
