Age, bodyweight, and mesenteric artery dimensions and vascular reactivity for 12 month old wild-type (Rln+/+) and relaxin-deficient (Rln−/−) mice.

Baseline (at 5 mmHg) artery dimensions: outer diameter (OD), inner diameter (ID) and wall thickness (WT). Vascular reactivity data: phenylephrine (PE); acetylcholine (ACh); 100 mM potassium PSS (Hi K); nitric oxide synthase inhibitor (L-NAME); indomethacin (Indo); 1-[(2-chlorophenyl) (diphenyl) methyl]-1H-pyrazole and apamin (T34 & Apa); maximum response (Emax); maximum relaxation (Rmax); pD2 sensitivity (−log EC50); N/D not determined. All values are expressed as mean ± SEM and N refers to the sample size. * significantly (PRln+/+ mice.Age, bodyweight, and mesenteric artery dimensions and vascular reactivity for 12 month old wild-type (Rln+/+) and relaxin-deficient (Rln−/−) mice.
