Effect of manganese exposure on MPTP neurotoxicities.

We used a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated mice model to evaluate whether manganese (Mn) exposure can affect MPTP-induced neurotoxicity. We randomly assigned adult male C57BL/6 mice (n=5-7 per group) the following treatments: SO, Mn(-) x MPTP(-); MO, Mn(+) x MPTP(-); SM, Mn(-) x MPTP(+); MM, Mn(+) x MPTP(+). Mn (MnCl(2).
