Potential source of asbestos in non-asbestos textile manufacturing company.
Recently, a worker with lung carcinoma and a metastatic brain tumor was diagnosed as having a work-related disease. He had been employed in a non-asbestos textile company for 25 years. Consequently, to identify and explore possible causative agents for lung cancer in a non-asbestos textile manufacturing company and establish a causal relationship between exposure and lung cancer, an epidemiolog...
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 کاملPenetration of cells by asbestos fibers
Studies on the behavior of asbestos fibers within tissues have shown that the only cells that regularly contain asbestos are macrophages and their derivatives. However, these cells actively incorporate the asbestos fibers by the process of phagocytosis, and there is little evidence of direct penetration. Examination of the gut lining after prolonged asbestos ingestion has shown no evidence of d...
متن کاملAsbestos 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 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 ...
