Mn Neurotoxicity: Manganism

Mar 19, 2013· Mn neurotoxicity can be mediated also by nonenzymatic autoxidation of catecholamines to 6-hydroxydopamine (6-OHDA). This would explain DA depletion from specific regions of the brain following Mn exposure (Selective lesions by manganese and extensive damage by iron after injection into rat striatum or hippocampus 1994).

Superoxide dismutase - Wikipedia

Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O − 2) radical into ordinary molecular oxygen (O 2) and hydrogen peroxide (H 2 O 2).Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging and is degraded by other ...
