FIG. 4.

Phenylephrine (PE)-induced contraction in mesenteric arterial rings of control and protein-restricted offspring with and without flutamide. Endothelium-denuded mesenteric arterial rings were incubated in Krebs buffer and then stimulated with increasing concentrations of PE. A) Phenylephrine contraction was measured and presented as percentage of maximal contraction. B) Phenylephrine -induced contractions were also calculated as percentage of 80 mM KCl contraction (n = 10–12 mesenteric arterial rings from five rats in each group).
