The association of phagocytosed asbestos dust with lysosome enzymes
…staining combined with electron microscopy. It was found that the acid phosphatase reaction was confined to the lysosome series of organelles, but that not all of these structures gave a positive reaction. In dust-containing macrophages…

The biological effects of mineral fibres
…In the studies reviewed, glass fibres injected into animals' body cavities produced mesotheliomas, while inhaled glass fibre produced little tissue reaction. Studies of glass fibre workers had so far been negative. The review also described reports…

Free radical activity of synthetic vitreous fibers: iron chelation inhibits hydroxyl radical generation by refractory ceramic fiber
…of salicylate. Presence of an iron chelator inhibited the ability of the RCF1 fibers to cause hydroxylation of salicylate, demonstrating that RCF1 generates hydroxyl radical by Fenton chemical reaction in the same way as amphibole asbestos.

Short-term inhalation and in vitro tests as predictors of fiber pathogenicity
…and SiC. However, measurements of BrdU uptake into lung cells showed that amosite and SiC produced a greater reaction than code 100/475, which itself caused no more proliferation than that seen in untreated lungs. These…
