Maximum changes (∆) of systolic blood pressure (∆SBP, A), mean arterial pressure (∆MAP, B), and heart rate (∆HR, C) following hemorrhage and microinjection of saline, GYK, and MK-801 into the lPAG column in 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 compared to the saline group

GYK: 1-(4-aminophenyl)-4-methyl-7,8-methylenedioxy-5H-2,3-benzodiazepine , lPAG : Lateral periaqueductal gray matter , Hem:hemorrhage
