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…

An assessment of the fibrogenic potential of two refractory fibres by intraperitoneal injection in rats
…tissue reaction was compared. Although the fibres differed considerably in surface properties and porosity the tissue reactions were identical and consisted of a mild chronic inflammatory response with a small amount of collagen present. The reaction…

Role of iron in the reactivity of mineral fibers
…chemical processes that implicate surface iron as a primary cause of toxicity are: free radical release, mobilization by chelators, iron-catalyzed reactions. Three kinds of solids are compared: (i) well-known toxic materials, for example asbestos…

Expression of Clara cell secretory protein in the lungs of rats exposed to silicon carbide whisker in vivo
…1 month, 3 months and 6 months of recovery time. The expression of CCSP was observed by reverse transcriptase-polymerase chain reaction (RT-PCR), Western blot and immunostaining. Exposure to 10 mg of SiCW decreased in…

Synchrotron X-ray microscopy reveals early calcium and iron interaction with crocidolite fibers in the lung of exposed mice
…inhaled asbestos fibers; (2) the extent of the deposition of these ions is proportionally directly related and (3) iron and calcium deposition on inhaled asbestos fibers is concomitant with the appearance of inflammatory and hyperplastic reactions.
