Transient changes (% change) in systolic right ventricular pressure (sRVP), mean arterial blood pressure (MABP) and heart rate (HR) in response to (a) ACh (3.0 µg kg−1 min−1 for 5 min), (b) sodium nitroprusside (SNP, 5.0 µg kg−1 min−1 for 5 min) and (c) BQ-123 (1 mg kg−1) for Dahl salt-resistant rats (Dahl-R; n = 7) and salt-sensitive rats (Dahl-S; n = 7). For comparative purposes, data for SD rats are also presented [§taken from Schwenke et al. (2011)]. *Significant increase/decrease in response to each intervention (P < 0.05). †Significantly different to SD rats (P < 0.05). |
