abstract：:There are many evidences suggest that ascorbate in the extracellular space can affect glutamate concentration in the rat's brain. In this report, we studied how ascorbate in microdialysis perfusion medium affected glutamate level at the striatum in freely-moving rats. Three perfusion mediums were used: 0, 250, and 400...
