Fig. 2. Blood pressure changes ( ${Delta}$ a) elicited by different doses of (A) sodium nitroprusside (SNP) and (B) phenylephrine (PE) at different ages of development. Open bars: 25 µg kg^–1 SNP and 30 µg kg^–1 PE, respectively; shaded bars: 50 µg kg^–1 SNP and 60 µg kg^–1 PE, respectively; closed bars: 100 µg kg^–1 SNP and 120 µg kg^–1 PE, respectively. Data are means ± S.E.M. (N=8). Dissimilar letters indicate differences between ages. All doses except the lowest dose of SNP at 60% of development induced significant changes in pressure.
