Abstract:

In the present study, we investigated the implication of oxidative stress and apoptosis under static magnetic field (SMF) in the brain and liver. Moreover, we estimated the protective role of selenium and vitamin E in rat tissues against disorders induced by SMF. Exposure of rats to SMF (128 mT, 1 h/day during five consecutive days) increased the activity of catalase (CAT) (+24 %) in the liver but not in the brain. By contrast, the same treatment failed to alter malondialdehyde (MDA) concentration in the brain and liver. Exposure to SMF also induced hepatocyte apoptosis through a caspase-independent pathway involving mitochondrial apoptosis-inducing factor (AIF) but not in the brain. Selenium and vitamin E supplementations to SMF-exposed rats restored liver CAT activity but failed to minimize liver apoptosis.
