Glycine-GluN1 binding site antagonist prevents glycine-induced functional recovery of ischemic stroke animals. For all the three experiments, Glycine (100 µg/100 g, icv) was administered at 3 h following I/R. Glycine-GluN1 binding antagonist L-689560 (L68; 0.1 mg/100 g, ip) is injected with MK-801 and strychnine at 30 min before glycine injection. (A) Animals treated with glycine (100 µg/100 g, icv) has lower scores of mNSS test at day 7 and 14 compared with I/R + Stry + MK + L68 + Gly group (n = 10; ANOVA test, *P < 0.05, vs. I/R + Stry + MK + L68 + Gly). (B) Animals treated with glycine has lower scores of beam-walking test at day 3, 7 and 14 compared with I/R + Stry + MK + L68 + Gly group (n = 10; ANOVA test, *P < 0.05, vs. I/R + Stry + MK + L68 + Gly). (C) Animals treated with glycine (100 µg/100 g, icv) treatment has higher ratio in MST test at day 7 and 14 compared with I/R + Stry + MK + L68 + Gly group (n = 10; ANOVA test, *P < 0.05, vs. I/R + Stry + MK + L68 + Gly). Stry: Strychnine; Gly: glycine; MK: MK-801.
