Maximum changes (∆) of systolic blood pressure (∆SBP, A), mean arterial pressure (∆MAP, B), and heart rate (∆HR, C) following saline, L- glutamate, GYK+ L-Glu, and MK-801+ L-Glu microinjection in the lPAG column in Hem hypotensive rats

Data are expressed as mean ± SEM. n = 6. One-way ANOVA and post hoc Tukey's test were used to analyze the changes. ***P<0.001, *P<0.05 compared to the control group. ## P<0.01 compared to the Hem group. ^^^ P<0.001 compared to the Hem+ L-Glu group.
