title: Dietary restriction decreases thiobarbituric acid-reactive substances generation in the small intestine and in the liver of young rats.
abstract: This study investigated the influence of dietary restriction on thiobarbituric acid-reactive substances (TBARS) contents and on the intracellular antioxidant defence system in the small intestine or liver of young rats. Four weeks of diet restriction (-40%) lowered the TBARS level in both organs. No variations were found for the superoxide dismutase and catalase activities; only liver seleno-dependent glutathione peroxidase was enhanced by the restriction. The protection appeared more marked in the intestine than in the liver, and would be dependent on glutathione concentration.
