Pulmonary reaction to long and short asbestos fibers is independent of fibroblast growth factor production by alveolar macrophages
This rat study asked whether alveolar macrophage secretions (scavenger cells in the lung's air spaces) explain why long, but not short, crocidolite fibers cause lung fibrosis. UICC crocidolite was separated into long fibers (mean 24.4 microns) and…

Chronic mesothelial reaction and toxicity of potassium octatitanate fibers in the pleural cavity in mice and F344 rats
…which are morphologically similar to asbestos particles, were shown to induce severe proliferative reactions in the pleural mesothelium in a previous experiment carried out over 21 weeks. The present study aims to determine whether these fibers…

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…

Fiber localization and its relationship to lung reaction in rats after chronic inhalation of chrysotile asbestos
…with histologic changes indicating marked epithelial injury. Increased amounts of fibers are also localized in the lung interstitium with continued exposure to asbestos and are associated with a progressive interstitial fibrotic reaction. Following cessation of exposure…

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…

Mineral-fluid interaction in the lungs: insights from reaction-path modeling
…from previous work described in the literature. Modeling of reaction paths in both closed and open systems confirms previous suggestions that chrysotile dissolves faster than tremolite in lung fluid, which offers an explanation for the apparent…

Cisplatin-induced sudden cardiac death with hemodynamic collapse: a severe adverse drug reaction: Case report
Cisplatin is responsible for a significant percentage of adverse drug reactions (ADRs) in oncology setting. A great proportion of cisplatin-induced severe adverse events are difficult to foresee, and giving premedication does not always prevent the…

Exposure to chrysotile asbestos causes carbonylation of glucose 6-phosphate dehydrogenase through a reaction with lipid peroxidation products in human lung epithelial cells
In this laboratory study, the authors exposed A549 cells, a human lung carcinoma cell line described as lung epithelial type II cells, to UICC chrysotile B asbestos for 5 hours. One comparison also used crocidolite. No people or animals were…

Hydroxyl radical production in the presence of fibres by a Fenton-type reaction
…of people who inhale them. Results in the present study however indicate that these fibres are able to produce hydroxyl radicals in the presence of hydrogen peroxide by a Fenton-type reaction. Since hydroxyl radical is…
