Abstract

Abstract Present study describes the effect of zinc (Zn) on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced dopamine depletion in mice brain. MPTP is a known neurotoxicant primarily causing marked depletion of dopamine (DA) levels in nigrostriatal dopaminergic system. Adult Male C57-mice were intraperitonially injected with 25 mg/kg MPTP in the presence or absence of zinc acetate. Twenty-four hours after treatment animals were sacrificed and DA levels were determined by high performance liquid chromatography in caudate nucleus of control and treated mice. The results showed that there was a marked depletion of DA in MPTP treated mice, whereas no change was observed in DA levels in mice treated with Zn when compare to controls. Interestingly, mice receiving MPTP in conjunction with Zn showed significantly lower DA levels in brain when compare to animals receiving MPTP alone. In summary the data suggest that Zn treatment potentiates depletion of dopamine in MPTP treated mice.
