Progressive lung cell reactions and extracellular matrix production after a brief exposure to asbestos
…this would be the most likely site of a significant cellular or fibrotic reaction. The characteristics and progression of tissue reactions occurring at first alveolar duct bifurcations after a single brief asbestos exposure was defined using…

Formation of 8-hydroxydeoxyguanosine by asbestos and man made mineral fibres
…were compared with chrysotile fibres for their capacity to hydroxylate 2-deoxyguanosine to 8-hydroxydeoxyguanosine, a reaction that is mediated by formation of hydroxyl radicals. All three fibres produced 8-hydroxydeoxyguanosine in the absence of H2O2…

Nelson v. Industrial Com'n of Arizona (1982)
…The court found that Mrs. Nelson had a meritorious excuse. Doctors and neighbors described an abnormal grief reaction that impaired her understanding, and the delay did not prejudice the carriers. It set aside the award and…

Warren W. Greene to Johns-Manville Sales Corporation on the Nix Compensation Settlement (1980)
…Greene states "that it was his impression that Johns-Manville's reaction would be either this lady settles at the negotiated amount for everything or we will stonewall her and she'll probably never leave (sic…

Keratin and epithelial membrane antigen immunoreactivity in nonneoplastic fibrous pleural lesions: implications for the diagnosis of desmoplastic mesothelioma
…EMA stained five of ten plaques and four of 11 lesions. Keratin also stained the fibrous reaction around six of eight metastases. Benign localized fibrous mesotheliomas and 16 fibrous lesions away from the pleura did not…

Immunohistological staining of reactive mesothelium, mesothelioma, and lung carcinoma with a panel of monoclonal antibodies
…but was present in most of the lung carcinomas. CEA seemed to be the single most useful marker in distinguishing carcinoma from mesothelioma in that a positive reaction for CEA would indicate carcinoma rather than mesothelioma.

Evaluation of the K2 asbestos screening test kit
…The kit, marketed as a field test, uses colour reactions to detect magnesium and iron, elements in asbestos minerals. It was tried on 30 building samples previously examined by optical microscopy and on 12 calibration preparations…

Adenomatoid tumor of ejaculatory duct
…stain for two prostate markers, prostate specific antigen and prostate specific acid phosphatase. It showed no reaction for factor VIII antigen. It contained faint focal mucin and some yellowish brown pigment. The authors separated it from…

Malignant mesothelioma and CEA staining
…which is neither tumor- nor organ-specific. The author added that CEA staining results are not valid unless this reaction is first removed by absorbing the antisera with NCA. Earlier reports describing CEA in mesothelioma had…

Gallium scanning in differentiating malignant from benign asbestos-related pleural disease
…no history of exposure. Scans were also positive in 3 of the 16 patients with benign disease (19%), and tissue removed from these three showed a strong inflammatory reaction. Among asbestos-exposed patients, the scan's…

Pathologic changes in the small airways of the guinea pig after amosite asbestos exposure
… where these fibers penetrated the airway walls, an interstitial inflammatory and fibrotic reaction (asbestosis) occurred. It is concluded that 1) amosite asbestos produces diffuse abnormalities throughout the noncartilagenous airways and possibly the cartilagenous airways as well…

The biological effects of mineral fibres
…In the studies reviewed, glass fibres injected into animals' body cavities produced mesotheliomas, while inhaled glass fibre produced little tissue reaction. Studies of glass fibre workers had so far been negative. The review also described reports…

Lipid peroxidation in microsomes induced by crocidolite fibres
…produced a concomitant induction in microsomal lipid peroxidation. This increase was very rapid as the reaction was almost complete within 10 min. The ability of these fibres to induce this process after a short period of…

Cytogenetic findings in an effusion secondary from pleural mesothelioma
…years earlier a similar episode had been diagnosed as tuberculous pleuritis. Routine examination of cells in the fluid showed only a nonspecific reaction of the lining cells, and a pleural biopsy found no signs of cancer…

A study of macrophage-mediated initiation of fibrosis by asbestos and silica using a diffusion chamber technique
…the chamber) from the target tissue. Fibrous reactions surrounding the chambers were quantitated by macroscopic and histological scoring, and by measurement of 14C glycine incorporated at the reaction site. Using this model the fibrogenicity of Rhodesian…

Pulmonary toxicology of silica, coal and asbestos

Reactions of asbestos-exposed workers to notification and screening
…In this study, we assessed reactions of asbestos-exposed workers to a letter notifying them of their risk for asbestos-related illnesses and the availability of a medical screening program. Two hundred forty-seven workers who…

"Labrador lung": an unusual mixed dust pneumoconiosis
…ferruginous bodies; one ferruginous body was identified as having a core of anthophyllite. A granulomatous reaction was seen in two biopsy specimens and typical silicotic nodules were found in two others. The relatively brief exposure, especially…

Dusts causing pneumoconiosis generate .OH and produce hemolysis by acting as Fenton catalysts
…were studied. The authors tested whether dusts act as Fenton catalysts, turning hydrogen peroxide into damaging hydroxyl radicals, a reaction in which iron or other metals take part. With ascorbate (vitamin C) present, amosite, chrysotile and…
