摘要：

In view of the emerging role of metals and particularly iron in the pathogenesis of several ischemic or degenerative CNS diseases, via a lipid peroxidative process, a model of slow iron-induced peroxidative damage in the rat brain cortex has been carried out. Iron-carbohydrate complexes were injected in the right brain cortex, and biochemical assays were performed on ipsilateral and contralateral samples two hours or seven days after injection. Iron-saccharate caused a significant increase in the ipsilateral cortex in TBARS, conjugated dienes and fluorescent substances seven days after injection, whereas no biochemical alteration was observed two hours after treatment. In order to prevent or to limit lipid peroxidation, some drugs known for chelating and/or scavenging activity were administered to iron-injected rats. DL-alpha-tocopherol, methylprednisolone, D-penicillamine significantly decreased the value of fluorescent products formed by iron-saccharate, whereas desferrioxamine was not effective.
