Asbestos law: victims' rights and industry's reaction
This paper was a review of U.S. law on asbestos-related diseases, not a medical study. The author described two routes to compensation: workers' compensation claims against employers, and product liability lawsuits against manufacturers and…

The ingestion of asbestos fibers
…which probably came from iron-containing macrophages. It is suggested that pleural plaques and hyaline nodules in the peritoneum represent a hypersensitivity reaction to ferritin protein coating on asbestos fibers. In South Africa only a few…

Pulmonary talc granulomatosis. A complication of drug abuse
…who had injected methylphenidate (Ritalin) tablets into their veins. Granulomatosis here means small clusters of inflammatory cells forming in the lungs in reaction to talc particles. The authors explained that talc is used as a filler…

The association of phagocytosed asbestos dust with lysosome enzymes
…staining combined with electron microscopy. It was found that the acid phosphatase reaction was confined to the lysosome series of organelles, but that not all of these structures gave a positive reaction. In dust-containing macrophages…

Inhalation carcinogenesis from various forms of asbestos
…amosite). A fibrogenic response to these dusts was observed in all five animal species, the severity corresponding to the extent of exposure (with reaction to chrysotile frequently very slight). Gerbils developed frequent alveolar proteinosis. Mice developed…

Immune adherence reactivity of rat alveolar macrophages following inhalation of crocidolite asbestos
…a statistically significant difference. Sheep red cells, which cannot take part in this reaction, stuck far less to macrophages from exposed rats. Treating the cells with antiserum against the complement component C3 reduced adherence to 4…

Antemortem diagnosis in two cases of malignant peritoneal mesothelioma
…the abdomen. A biopsy taken by peritoneoscopy, a scope inserted into the abdomen, was read as consistent with mesothelioma or an inflammatory reaction. The Armed Forces Institute of Pathology then confirmed mesothelioma. He died, and autopsy…

Induction of interferon in human subjects by poly I:C
…responsive again after a 10-day period. The authors could not define this refractory period precisely. Fever was the only consistent clinical reaction. Serum was tested from 19 patients, and none showed complement-fixing antibodies against…

Nephrogenic metaplasia (adenomatoid tumors) of bladder
…23 men and 5 women. The authors concluded that their cases appear to support the theory that these lesions are a reaction of the bladder lining to chronic inflammation or irritation. They considered it likely that…

Lymphohematogenous spread of asbestos
…kidney, brain and other organs, and of what damage they cause. The author concluded that knowing the injury reaction and tissue dose-response would help determine how much asbestos, and what kind, if any, humans can…

Milky spots (Taches laiteuses) as structures which trap asbestos in mesothelial layers and their significance in the pathogenesis of mesothelial neoplasia
…were seen in either group. The authors concluded that milky spots may trap blood-borne particles. They suggested that the cells' reaction to trapped fibres might be an early step toward tumours of the body cavities.

Response of cell cultures to asbestos fibers
The reaction of macrophages to asbestos and glass fibers was studied by light and by electron microscopy. Measurements were made of LDH release, staining with erythrosine B, and lactate production. Size and shape of asbestos fibers…

Ferruginous bodies in benign fibrous pleural plaques
…evidence suggests that benign fibrous plaques may form in the pleura as a reaction to inspired asbestos. The ferruginous bodies formed in reaction to asbestos and other respirable fibers have virtually never been demonstrated in these…

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…

The adsorption of biological macromolecules by mineral dusts
…strong” adsorption reactions were noted with serum proteins, the latter being considered as the most specific for each mineral and perhaps the most important physiologically. The implications of the observed adsorption phenomena to the reaction between…

Correlation between the tissue response and asbestos fiber content
…and here secondary factors may be concerned. Electron microscopy suggests that optically visible fibers constitute a reasonably constant proportion of the total irrespective of the pathological reaction. Light microscopy may thus afford a guide to the…

Experimental infective pneumoconiosis: effect of asbestos dust and Candida albicans infection on the lungs of rhesus monkeys
…albicans infection alone caused acute inflammatory reaction in the early stages while at the termination of experiment (330 days) the only evidence of pulmonary candidiasis was a few small fibrotic foci of compactly arranged reticulin fibers…
