Peroxidation potential of rat thymus during development and involution.
The thymus of rats of ages between 1 and 7 months was homogenised and subjected to oxidative stress induced by iron salts. Lipid peroxidation, protein thiols and glutathione status were evaluated. The thymus of rats of 1 month of age exhibited lower susceptibility to the radical attack with respect to the thymus of rats between 3 and 7 months of age. This susceptibility was correlated with the content of polyunsaturated fatty acids and of lipophylic chain-breaking antioxidants.
