Figure 1

Effect of NaHS on blood pressure and endothelial-dependent renal arterial contraction. (a) Mean arterial pressure (MAP); (b) endothelium-dependent contractions (EDCs) in four groups; (c) original recording of EDCs in four groups. Data are means ± SEM. versus Sham; versus 2K1C vehicle. in each group for MAP measurement; in each group for EDCs measurement.
