[Effect of alimentary factors on the production of primary and final products of lipid peroxidation].

In blood plasma, liver, and brain of pubertal female Wistar line rats the level of diene conjugates, fluorescent lipopigments and vitamin E were studied as a function of different diets: control, fish and fish with addition of vitamin E. The obtained results show that in the brain tissue the role of vitamin E as an antioxidant is more pronounced, but dynamical equilibrium between the oxidation substrates and antioxidants after alimentary deficiency of vitamin E is restored in the nervous tissue more slowly than in the liver and blood plasma. In the organism of young animals fluorescent pigments are not accumulated in form of inert products, but behave as normal metabolites.
