| Outline of Final Research Achievements |
Magnesium-L-threonate (Mg-L-Th: It had been reported that the oral intake of Mg-L-Th increased the concentration of Mg in the cerebrospinal fluid by 10 to 20%. Mg-L-Th was purchased from two companies (A and B).) was administered to the alpha-synuclein transgenic (aSyn tg) mice, which are considered to be a model of Parkinson disease, and the wild type (WT) mice. Gait of aSyn tg mice, such as width of forefoot and hind foot, was not improved by Mg-L-Th administration. In addition, frequency of jumping to the cage wall of aSyn tg mice was not decreased. But the concentration of dopamine in the neostriatum, which was lower in aSyn tg mice than WT mice, was increased significantly in aSyn tg mice by Mg-L-Th from A company.
