Abstract Levels of lipoperoxides and hydrophobic scavengers of free radicals were estimated in n-hexane extracts of myocardial biopsy specimens taken from cardiac patients (children and adults) during surgical operations. Ultraviolet spectra of these extracts were found to contain four absorption bands with peaks at 214, 233, 258, and 298 nm that characterize the levels of diene and triene conjugates. A comparison of the data obtained for children and adults suggested that the total antiradical activity of the cardiac muscle decreases while its content of vitamin E remains virtually unchanged during ontogeny. Significantly reduced vitamin E levels were noted in specimens from patients with chronic ischemic heart disease.
