Representative traces (a) and relaxant effect (b) of ACh on the tonic contractions induced by 3 × 10⁻⁷ M PHE in SG (○), SG50 (□), SG150 (∆), and SG500 (◊) groups in the rat aorta in the presence of endothelium. The symbols and vertical bars represent the mean and S.E.M., respectively (n = 05 indicates the number of samples per treatment). Ach: acetylcholine. Sedentary saline group (SG) and sedentary groups supplemented with S. platensis at 50 mg/kg (SG50), 150 mg/kg (SG150), and 500 mg/kg (SG500). Two-way ANOVA followed by Bonferroni's posttest. ^∗p < 0.01 (SG vs. SG150, SG vs. SG500), ^#p < 0.01 (SG50 vs. SG150, SG50 vs. SG500), ^†p < 0.01 (SG150 vs. SG500).
