ABSTRACT: The present work investigated the behavioural and biochemistry effects of moderate exposure to a static magnetic field (SMF) in rats. SMF effects were evaluated in sham- and SMF-exposed rats. Adult Wistar rats were exposed for 1 hour per day for 5 consecutive days to 128 millitesla (mT) SMF. Then, their motor skills were tested using a Stationary beam and Suspended string test. Iron level in plasma and brain (i.e. frontal cortex, basal ganglia, hippocampus and cerebellum) was measured. No significant change was observed between sham and SMF-exposed rats in the Stationary beam and Suspended string test. However, the same treatment induced an increase in plasma transferrin content (+25.4%) and decreased the iron level in plasma (-16.2%). The SMF treatment failed to alter the iron concentration in the brain. The findings indicate that SMF exposure induced iron deficiency in plasma but did not induce motor-skills deficit.
