title: Neuroprotective Potential of Superparamagnetic Iron Oxide Nanoparticles Along with Exposure to Electromagnetic Field in 6-OHDA Rat Model of Parkinson's Disease.
abstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting mainly the dopaminergic neurons of the substantia nigra leading to various motor and non-motor deficits. We explored the neuroprotective potential of superparamagnetic iron oxide nanoparticles (IONPs) along with exposure to EMF in 6-OHDA rat model of PD. IONPs were implanted at the site of lesion and 24 h thereafter the rats were exposed to magnetic fields 2 h/day for one week. Bilateral lesions of the striatum were made with 6-OHDA. The rats in all the intervention groups improved progressively over the days and by post-surgery day 4 they were active and bright. We observed a significant beneficial effect of the IONPs implantation and MF exposure on feeding behavior, gait and postural stability. There was a significant enhancement of mitochondrial function and attenuation of lesion volume in all the intervention groups as compared to PD. The results demonstrate neuroprotective effect of iron oxide nanoparticle implantation and magnetic field exposure in an in vivo 6-OHDA rat model of PD.
