  1. The baseline MSAP, HR and power density of vasomotor components of SAP spectrum were measured at 120 min, 24 h, or day 7 respectively, after microinjection bilaterally into RVLM of other test agents, ERα or ERβ ASON or SCR, or AdGFP or AdPTEN. All values are expressed as mean ± SEM; n = 6-7 animals per experimental group. Any significant differences (P < 0.05) were not detected between all the test agent groups and aCSF group in the Student’s t-test.
