Figure 1
Effects of GPS on the vasorelaxation of thoracic aortic rings. (a) Chemical structure of GPS. (b) Direct effects of GPS (5, 10, 20, 40, 80, 160, and 320 μΜ) on the thoracic aorta tension. (c) Cumulative concentration-response curves of GPS (5, 10, 20, 40, 80, 160, and 320 μΜ) on endothelium-intact (E+) and endothelium-denuded (E-) aortic rings precontracted with 1 μM PE or (d) 60 mM KCl. Data are presented as (). compared to the control group.
