Pleural mesotheliomas in Sprague-Dawley rats by erionite: first experimental evidence.
Erionite and crocidolite fibers were tested for carcinogenicity by intrapleural and intraperitoneal injection (una tantum) in 40 Sprague-Dawley rats per route for each fiber type. Pleural mesotheliomas were found in nine of ten animals that died within a year after intrapleural injection with erionite fibers. No pleural tumors were found among the animals treated at the same time and in the sam...
متن کاملErionite exposure in North Dakota and Turkish villages with mesothelioma.
Exposure to erionite, an asbestos-like mineral, causes unprecedented rates of malignant mesothelioma (MM) mortality in some Turkish villages. Erionite deposits are present in at least 12 US states. We investigated whether increased urban development has led to erionite exposure in the United States and after preliminary exploration, focused our studies on Dunn County, North Dakota (ND). In Dunn...
متن کاملMesotheliomas--asbestos exposure and lung burden.
The assessment of asbestos fibres in the lungs at post mortem in groups of mesotheliomas, groups occupationally exposed to asbestos, and controls has shown that all these groups contain significant levels of asbestos as a lung burden. The amounts in each group are dependent on the degree of past exposure, being highest in those cases with a known or extrapolated occupational exposure, less in t...

METHODS These cases are in non-occupationally exposed people, appearing to have resulted from exposure to contamination of the community, the surrounding forested area, and areas in proximity to the...
متن کاملExcess of mesotheliomas after exposure to chrysotile in Balangero, Italy.
BACKGROUND Chrysotile from the mine in Balangero, Italy is considered to be free of tremolite. In a cohort study of miners and millers only two pleural cancers were reported, a finding considered to indicate that chrysotile has a low potency for inducing mesothelioma. However, follow-up ended in 1987 and white-collar workers and the employees of subcontractors were not studied. METHODS To com...
