“…Studies have shown that in addition to the injury effect of glutamate, glycine also has the synergistic action, and its release may increase brain injury (Ohtani et al, 2000;Saransaari and Oja, 2001;Heurteaux et al, 2006;Masaya et al, 2007). GABA can inhibit the release of excitatory amino acids or resist excitotoxicity (Centonze et al, 2001;Wang et al, 2001;Saransaari and Oja, 2008;Jia et al, 2009). Therefore, synthetically analyzing the change of amino acids concentration and interrelationship will further understand the essence of cerebral lesion following ischemia.…”
