Enhancement of enzyme-catalyzed production of reactive oxygen species by suspensions of "crocidolite" asbestos fibres.
Ethylene release from methylthio-ketobutyric acid is an indicator for activated oxygen species of the OH.-radical type. Xanthine oxidase plus xanthine or diaphorase in the presence of NADH and juglone produce OH.-type oxy-radicals. The production of reactive oxygen species in these enzymatic systems is enhanced by "crocidolite" asbestos fibres.
