Puerarin treatment ameliorated (A) MAP, (B) HR, (C) NE in plasma levels and (D) NF-κB p65 activity in the PVN of salt-induced prehypertension. Non-invasive blood pressure measurement was used to detect the changes of mean blood pressure and heart rate of rats in each group. ELISA kits were used to evaluate the levels of NE in plasma and NF-κB p65 activity in the PVN. The data are expressed as the means ± SEM (n = 7 rats/group). * p < 0.05, ** p < 0.01 vs. control groups; ^† p < 0.05 vs. puerarin-pretreated groups.
