[Free-radical lipid oxidation in rabbits with the alimentary peroxidation syndrome]

The results are presented of the study of free radical oxidation of lipids in rabbits with alimentary peroxidation syndrome. A long-term feeding of the animals with a ration devoid of alimentary antioxidants reproduces the main biochemical changes in the blood and tissues characteristic of old animals. It has been revealed that the intensity of EPR signals of lyophilized tissues increased proportionally to the animals' age and to the duration of their maintenance on the ration devoid of antioxidants. A conclusion has been made that the deprivation of the rabbits of alimentary antioxidants accelerates aging.
