[Activation of lipid peroxidation in emotional-pain stress]

Accumulation of primary and secondary products of lipid peroxidation (PLP) in different tissues of Wistar rats under emotional-pain stress (EPS) was studied using UV-spectrophotometry and fluorescense of Schiff bases. It was shown that under EPS the amount of PLP increased mostly in the heart and to a lesser degree in the skeletal muscle and brain. An increase in hydroperoxidases in all the organs studied was less than that in the PLP end-products, i. e. flourescent Schiff bases.
