Age, bodyweight, and mesenteric artery dimensions and vascular reactivity for 12 month old wild-type (<i>Rln</i>^+/+) and relaxin-deficient (<i>Rln</i>^−/−) 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 (P<0.05) greater than Rln+/+ mice. Age, bodyweight, and mesenteric artery dimensions and vascular reactivity for 12 month old wild-type (Rln+/+) and relaxin-deficient (Rln−/−) mice.5mmHg基线状态下的动脉形态参数：外径（outer diameter, OD）、内径（inner diameter, ID）及管壁厚度（wall thickness, WT）。血管反应性相关检测数据包括：去氧肾上腺素（phenylephrine, PE）、乙酰胆碱（acetylcholine, ACh）、100mM钾离子PSS溶液（Hi K）、一氧化氮合酶抑制剂（nitric oxide synthase inhibitor, L-NAME）、吲哚美辛（indomethacin, Indo）、1-[(2-氯苯基)(二苯基)甲基]-1H-吡唑（T34）与蜂毒明肽（apamin, Apa）；最大收缩反应（maximum response, Emax）、最大舒张反应（maximum relaxation, Rmax）、pD2敏感性（−log EC50）；N/D代表未测定。所有数据均以平均值±标准误（standard error of the mean, SEM）表示，其中N为样本量；标记*表示该数值较Rln+/+小鼠显著升高（P<0.05）。本数据集涵盖12月龄野生型（wild-type, Rln+/+）及松弛素缺陷型（relaxin-deficient, Rln−/−）小鼠的年龄、体质量、肠系膜动脉形态参数及血管反应性数据。
