Blood pressure (BP) measurements by radiotelemetry. Measurements of systolic and diastolic BP of SS rats and Resp18mutant rats fed with low- (SS = 5, Resp18mutant = 5) (A) and high-salt diets (SS = 12, Resp18mutant = 10) (B). Rats were monitored for BP after surgical implantation of radiotelemetry transmitters. Data plotted are the recordings obtained once every 5 min continuously for 24 h and averaged for 4 h intervals; Data are means ± SE. Levels of statistical significance were analyzed by t-test *P ≤ 0.05.
