Pulmonary granulomatous reaction: talc pneumoconiosis or chronic sarcoidosis?
A chronic pulmonary granulomatous reaction was associated with an almost identical clinical picture in two patients exposed to talc. In both patients lung biopsy showed the deposition of talc particles and a heavy granulomatous reaction. At…

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…

Enhanced lipid peroxidation and lysosomal enzyme activity in the lungs of rats with prolonged pulmonary deposition of crocidolite asbestos
…for example 75.87 versus 30.81 mg at three months), and microscopy showed granulomas containing fibres. The fibrotic reaction tended to diminish by seven months. Activity of two lysosomal enzymes, beta-glucuronidase and cathepsin D…

Quantitative x ray microanalysis of pulmonary mineral particles in a patient with pneumoconiosis and two primary lung tumours
…fire clay mineral. The authors concluded the method reliably identified individual particles. They noted it cannot show whether the dust caused the tissue reaction, and that the particles analysed probably did not represent all minerals present.

Experimental asbestosis: an investigation of functional and pathological disturbances. II. Results for chrysotile and amosite exposures
…not until about 70 weeks for animals exposed when three months old. No fibrotic reaction was seen during the 70 weeks of the amosite experiments. The relationships between pathological and functional changes throughout these experiments are…

Biphasic lung diffusing capacity: detection of early asbestos induced changes in lung function
…choice in subjects with an isolated decrease in DLCO. Exposure to asbestos can be associated not only with a reduction in DLCO, but also with a temporary increase in DLCO caused by a subclinical inflammatory reaction.

The value of anticarcinoembryonic antigen, human milk factor globulin, and antikeratin antibodies in differentiating mesothelioma from lung carcinoma
…some mesotheliomas, reduces the value of the reactions in the individual case. Medical panels adjudicating compensation claims should not use these reactions as the sole criteria in deciding the origin of the tumours in these cases.

A histochemical study of the asbestos body coating
…after iron extraction were tested by histochemical methods for mucopolysaccharides. The results of the reactions suggest that acid mucopolysaccharides are present in the coating of most bodies. During the formation of the bodies acid mucopolysaccharides might…
