Data are expressed as mean ± standard deviation of mean or median with 25 and 75 percentiles; numbers in parentheses indicate the numbers of animals included in each experimental group. C: control group (no supplementation with vitamin D); VD3: supplemented with 3,000 IU VD/kg of chow; VD10: supplemented with 10,000 IU VD/kg of chow. pD2: indicates -log EC50 (the concentration of agonist producing half-maximal response); Phe: phenylephrine; E+: endothelium-intact vessels; E−: endothelium-denuded vessels; Ach: acetylcholine; SNP: sodium nitroprusside. * p
