Plasma GABA concentrations in mice administered with peroral (po) vs. intraperitoneal (ip) GABA. Time course of GABA concentrations in the postcaval vein plasma after po administration of GABA (200 mg/kg; closed circle) or ip injection of GABA (200 mg/kg; open circle, 20 mg/kg; open triangle). n = 4–6. ## p < 0.01 by one-way ANOVA followed by Dunnett’s test vs. 0 min in each group. GABA: Gamma-aminobutyric acid.
