Activation of UICC crocidolite: the effect of conversion of some ferric ions to ferrous ions
…The amount of iron in asbestos fibers, its oxidation state, and its availability to specific chelating agents determine their ability to catalyze the aforementioned reactions. In the present study, the activation of UICC crocidolite was achieved…

Crocidolite-induced lipid peroxidation in rat lung microsomes. I. Role of different ions
…in rat lung microsomes both from rats pretreated with 3-methylcholanthrene and from untreated controls. This increase was dependent on the concentration of these ions in the reaction mixture. Crocidolite alone increased peroxidation in microsomal fractions…

Cellular mechanisms of reactive oxygen metabolite generation from human polymorphonuclear leukocytes induced by crocidolite asbestos
…an enhancement. We conclude that crocidolite-induced ROM generation involves a cell surface reaction due to influx of extracellular calcium through calcium channels and the activation of NADPH oxidase on the PMN cell membrane. This hypothesis…

Manifestations of cellular immunity in the rat after prolonged asbestos inhalation. II. Alveolar macrophage-induced splenic lymphocyte proliferation
…some respects, to the lymphoproliferative response evoked by sodium periodate-treated control macrophages, since both these reactions peaked at 72 hr and were abolished by treatment of the macrophages with the reducing agent, L-cysteine. This…
