a Passive lumen diameters (mean ± SEM) of uterine radial arteries (RA) from all groups measured at 80 mm Hg in a relaxing solution containing 100 μM papaverine and 10 μM diltiazem. Note the approximately 35% increase in lumen diameter in the LP-C vs. NP-C groups that is indicative of expansive remodeling. Different letters denote statistical significance (p < 0.05); the same letter denotes statistical similarity (p ≥ 0.05). b Wall thickness of the same arteries as in a at 80 mm Hg. Values presented as mean ± SEM. Different letters denote statistical significance (p < 0.05); the same letter denotes statistical similarity (p ≥ 0.05). For both a and b, n values are: NP-C 12, NP-L 10, NP-L+H 6, LP-C 12, LP-L 15, LP-L+H 12.
