Figure 3From: Nitric oxide pathway-mediated relaxant effect of aqueous sesame leaves extract (Sesamum radiatum Schum. & Thonn.) in the guinea-pig isolated aorta smooth muscleMean relaxant concentration-response curve for the extract of Sesamum radiatum Schum. & Thonn in endothelium-intact (A) or in endothelium-denuded (B) guinea-pig isolated aorta preparations in the absence (□) and in the presence (▲) of L-NNA. Data are shown as mean ± s.e.m., expressed as the absolute values of percentage of the maximal response of n experiments (n = 4–6, p < 0.05).Back to article page
