<dcterms:abstract xml:lang="fr">L’objectif de notre travail consiste à caractériser des nanoparticules d’oxyde de fer (Fe3O4) et étudier leur toxicité aiguë chez le rat Wistar. Nos résultats ont montré que l’administration orale aiguë des Fe3O4, entraîne une altération dose- et temps-dépendante des paramètres du stress oxydant ainsi qu’une atteinte hépatique. En ce qui concerne l’étude in vitro sur des mitochondries isolées, nos résultats ont montré que ces nanoparticules n’altèrent ni les différents complexes de la chaîne respiratoire mitochondriale ni le couplage mitochondrial, et ceci dans aucun des organes étudiés (cerveau, cœur, poumon, foie et reins) et quelle que soit la concentration utilisée (100, 200, 300 et 500 μg/ml), alors que les mitochondries hépatiques isolées des rats âgés (18 mois), une altération est observée au niveau de tous les complexes de la chaîne respiratoire mitochondriale hépatique ainsi que pour le couplage mitochondrial quelle que soit la concentration utilisée (250, 300 et 350 μg/ml) alors que pour les rats jeunes (3mois) on n’observe aucune altération.</dcterms:abstract>
<dcterms:abstract xml:lang="en">The objective of our work is to characterize iron oxide nanoparticles (Fe3O4) and study their acute toxicity in Wistar rats. Our results showed that acute oral administration of Fe3O4, results in a dose and time-dependent alteration of oxidative stress parameters as well as liver damage. Regarding the in vitro study on isolated mitochondria, our results showed that these nanoparticles do not adversely affect the various complexes of the mitochondrial respiratory chain or mitochondrial coupling in any of the organs studied (brain, heart, lung, liverand kidneys) and regardless of the concentration used (100, 200, 300 and 500 μg/ml) while the isolated liver mitochondria from aged rats (18 months), an alteration is observed at all the complexes of the liver mitochondrial respiratory chain as well as the mitochondrial coupling regardless of the concentration used (250, 300 and 350 μg/ml), whereas for the young rats (3 months) no change is observed.</dcterms:abstract>
