Assessment of role of methyl cobalamine in excitotoxic effects of glutamicaid

ABSTRACT

Neurotoxicants and environmental pollutants cause neuronal damage and may damage myelin sheath. Since Methyl cobalamine [B12] has effect on myelin sheath formation it was hypothesized that B12 administration in case of nerve damage by some neurotoxicants may be protected or corrected by B12 administration. [Braun, 1977 and Braun, 1980]. For generations physicians have recommended B-vitamins especially B12 for neuropsychiatric symptoms. In present study neuroprotective role of B12 is assessed. Present work was planned to evaluate the therapeutic or prophylactic role of B12 in nerve damage by neurotoxicant i.e. glutamic acid. Present study revealed no significant neuroprotection or defensive regimen offered by B12 for neurotoxic damage. Glutamic acid is probably affecting neurons or dentritis sparing myelin sheath. Neuroprotection expected by B12 may be applied only to myelin sheath
