Recent evidence for the occurrence of in vivo lipid peroxidation in th
e context of cerebral ischemia/reperfusion, as detected by classical t
ests such thiobarbituric acid reactivity and conjugated diene absorban
ce, is critically reviewed. Despite the widespread perception that lip
id peroxidation is well-established and to be expected under such circ
umstances, in general these detection methods have not been applied wi
th rigor sufficient to prove the quantitative existence of lipid perox
ides unequivocally. The development of sensitive methods which can be
utilized in small tissue samples at early times after brain injury is
needed. In particular, the conditions necessary for the establishment
of a more rigorous and sensitive method of conjugated diene detection
in terms of difference spectral analysis are detailed and illustrated.
In addition, a new autofluorescence in the far-ultraviolet region is
shown to be associated with oxygenated conjugated diene-containing com
pounds. Copyright (C) 1996 Elsevier Science Ltd.
