[Lipid peroxidation processes and the dynamics of shifts in the cholesterol level in plasma and erythrocytes under the influence of low-frequency acoustic oscillations].

Distinct alterations in lipid peroxidation, in content of alpha-tocopherol and cholesterol fractions were observed in rat blood plasma and erythrocyte membranes after long-term low-frequency acoustic oscillations (105 decibels, diurnally, within 3 months). Under these conditions activities of superoxide dismutase and erythrocyte Na+, K+-ATPase were also altered. The rate and direction of the enzymatic activity alterations correlated with the duration of the acoustic oscillation exposure and the patterns studied. Enrichment of blood plasma and erythrocyte membranes with alpha-tocopherol within 2-4 weeks of the acoustic oscillation is considered as an important phenomenon.
