Figure 3
Vascular reactivity of thoracic aorta rings with (+E) or without (−E) endothelium from animals of four different groups: Saline (non-Pb-exposed), NaHS (non-Pb-exposed + NaHS); Pb (Pb-exposed), and Pb + NaHS (Pb-exposed + NaHS). ((a) and (b)) KCl-induced contraction. ((c) and (d)) PHE-induced contraction. (e) ACh-induced relaxation. (f) ACh-induced relaxation in presence of L-NAME. Values represent mean ± SEM. . versus NaHS group; versus Saline group; versus Pb group.
