Relaxation of fetal abdominal aortas in response to increasing doses of SNP; comparisons between SC-treated and control dams. A–D: arteries were precontracted with EC₈₀ dose of U46619. SNP dose-response curves were compared using two-way ANOVA followed by a Bonferroni post hoc test where appropriate. All data are expressed as means ± SE (n = number of animals). **P < 0.01. Fetuses were harvested from either SC-treated dams (gray) or control dams (black). Asterisks denote level of significance using Bonferroni post hoc test. *P < 0.05, **P < 0.01, ***P < 0.001.
