Samples of rockwool and glass fibre were compared with chrysotile fibres for their capacity to hydroxylate 2-deoxyguanosine to 8-hydroxydeoxyguanosine, a reaction that is mediated by formation of hydroxyl radicals. All three fibres produced 8-hydroxydeoxyguanosine in the absence of H2O2. The chrysotile fibres were most potent and produced about ten times more of the modified nucleoside than rockwool and glass fibre. This investigation shows that not only asbestos but also man made mineral fibres are able to modify nucleosides.
将岩棉和玻璃纤维样本与温石棉纤维相比较,以研究它们将2-脱氧鸟苷羟基化为8-羟基脱氧鸟苷的能力,该反应由羟基自由基的形成介导。在没有过氧化氢的情况下,所有三种纤维均能产生8-羟基脱氧鸟苷。温石棉纤维的作用最强,产生的修饰核苷比岩棉和玻璃纤维多约十倍。这项研究表明,不仅石棉,人造矿物纤维也能够修饰核苷。
