Abstract:Rat aging from 4 to 12 mo was accompanied by hippocampus and frontal cortex mitochondrial dysfunction, with decreases of 23 to 53% in tissue and mitochondrial respiration and in the activities of complexes I and IV and of mitochondrial nitric oxide synthase (mtNOS) (P < 0.02). In aged rats, the two brain areas showed mitochondria with higher content (35-78%) of oxidation products of phospholipids and proteins and with higher (59-95%) rates of O(2)(-) and H(2)O(2) production (P < 0.02).
