[Binding of 3H-serotonin, 3H-diazepam and lipid peroxidation in brain membranes].

It was demonstrated that the processes of lipid peroxidation in brain tissues of rats induced by hyperoxia and Fe-ascorbate system in vivo and in vitro significantly influence specific binding of serotonin and diazepam. Lipid peroxidation caused various changes in the ability to bind utilized ligands: 3H-serotonin binding decreased by 53%, while that of 3H-diazepam increased by 30%. Preliminary administration of the synthetic antioxidant 4-methyl-2,6-ditretbutylphenol prevented these changes.
