[Lipid peroxidation in terminal and extreme conditions].

It was demonstrated in experiments with cats, who survived a 5-minute clinical death caused by a prolongated blood loss, that the determination of lipid-peroxidation dynamic indices, made in incubated homogenates, reveals the altering ratios between the pro- and anti-oxidant activities as well as those ratios leveled by rapid shifts in hemodynamic parameters; it also displays the quantitative, qualitative and temporal differences of such ratios in the brain, liver and kidneys at dying and immediately after reanimation, which can not be detected by determining the content of lipid-peroxidation products in tissues in vivo.
