pubmed-article:1324206 | pubmed:abstractText | The formation of reactive free radical species in sheep erythrocytes challenged with dimethyldisulphide, a brassica-derived haemolysin, has been investigated by electron spin resonance spectroscopy using the spin trap alpha-(4-pyridyl 1-oxide)-N-tert-butylnitrone. Erythrocytes exposed to this agent undergo a burst of free radical activity as demonstrated by the appearance of a spin adduct. The results suggest that haemolytic anaemia which can occur in sheep grazing forage brassicas is a consequence of oxidative stress. | lld:pubmed |
