[Activation of lipid peroxidation and its prevention with ionol during mechanical asphyxia followed by resuscitation].
It was shown in experiments on random-bred male rats that during mechanical asphyxia, lipid peroxidation in the brain, heart, lungs and skeletal muscles experiences activation. At the beginning of the resuscitation measures under elevated tissue oxygenation there is a further increase in the intensity of lipid peroxidation, whereas the content of lipid hydroperoxides and Schiff's bases approaches the initial values only after 3 months. It is assumed that excessive activation of lipid peroxidation plays the key role in the pathogenesis of the postresuscitation disease. Preliminary administration of the synthetic antioxidant ionol in a dose of 30 mg/kg reduces activation of lipid peroxidation in all the organs and tissues under study, improves energy supply of the brain and heart, and decreases 3-fold the lethality in the early postresuscitation period.
