Asbestos fibers, plasma and inflammation.
Fibrin clots have been detected at sites of inflammation, and kinins have been implicated as mediators of the vascular phenomena of acute inflammation, systemic shock, and disseminated intravascular coagulation. It is now reported that both negatively and positively charged asbestos fibers shorten the partial thromboplastin time of human plasma, indicating coagulation of the plasma. A sample co...
متن کاملPulmonary asbestos bodies and asbestos fibers as indicators of exposure.
OBJECTIVES The aim of the study was to analyze the correlation between pulmonary concentrations of asbestos bodies and asbestos fibers and to characterize asbestos body counts from lung tissue of Finnish patients occupationally exposed and unexposed to asbestos. METHODS Ninety-nine surgically treated lung cancer patients were investigated. The number of asbestos bodies in iron-stained 5-micro...
متن کاملThe ingestion of asbestos fibers
Feeding of baboons with crocidolite showed small numbers of asbestos needles 0.5-1 mum in ashed tissue of the gut wall, 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 peritoneal mesotheliomas come from ...
متن کاملMagnetic anisotropy of asbestos fibers
The anisotropy of magnetic susceptibility of single asbestos fibers is measured. The alignment of both chrysotile and crocidolite fibers in magnetic fields is found to be due to the anisotropy. The average measured anisotropy of volume susceptibility is 0.40310 for chrysotile and 83310 for crocidolite. Fiber shape effects are estimated to contribute, on average, about 10% and 6%, respectively, ...
متن کاملTHEORY, EXPERIMENT AND PRACTICE OF SLAG ATTACK OF REFRACTORIES
Penetration and dissolution mechanisms are reviewed for predominantly single-phase oxide, two phase oxide and oxide-carbon composite refractories by liquid silicate slags. Theoretical models of these processes, as well as static (sessile drop, dipping and crucible) and dynamic (rotating finger and rotary slag) experimental tests, along with their practical limitations are considered. Direct (co...
