Agonist-induced contraction in mesenteric artery. Traces showing that after 1 μM Phe (A) or 10 nM ET-1 (C) treatment for 10 minutes, 2.5 mM Ca2+ application-induced vessel contraction in mesentery arteries from young and aged rats. B and D, present vessel tension changes in response to extracellular Ca2+ application after Phe (B) or ET-1 (D) treatment in mesentery arteries from young and aged rats. Values are presented as the mean ± SEM (n = 5); **P < 0.01. Young (3 months old) versus aged (22 months old).
