Asbestos bodies and fibers in lung tissue
نویسندگان
چکیده
It is suggested that the ratio of asbestos bodies observable by light microscopy to asbestos fibers counted by electron microscopy be examined in a series of cases of asbestosis of varying severity. If the ratio is reasonably constant an estimate of fiber content could be made from the more easily conducted count of asbestos bodies by light microscopy.

In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...

متن کاملAccumulation of radium in ferruginous protein bodies formed in lung tissue: association of resulting radiation hotspots with malignant mesothelioma and other malignancies
While exposure to fibers and particles has been proposed to be associated with several different lung malignancies including mesothelioma, the mechanism for the carcinogenesis is not fully understood. Along with mineralogical observation, we have analyzed forty-four major and trace elements in extracted asbestos bodies (fibers and proteins attached to them) with coexisting fiber-free ferruginou...
