Amelioration of Hypertension by Oryeongsan through Improvements of Body Fluid and Sodium Balance: Roles of the Renin-Angiotensin System and Atrial Natriuretic Peptide System

Figure 7

Effects of Oryeongsan (ORS) on the levels of plasma renin activity (PRA) and aldosterone (a), renin contents (b), and its gene expression (c) in the kidneys from Sham (S) and hypertensive (H) rats. Number of experiments: n = 8 for each of the Sham groups and n = 9 for each of the hypertensive groups for plasma levels of PRA and aldosterone; n = 4 for renin contents and renin mRNA of kidneys (left and right). Open bars, vehicle-treated (-ORS); closed bars, ORS-treated (+ORS). and versus Sham (S-); ## and ### versus hypertensive rats treated with vehicle (H-). (a) Plasma, (b) kidney, and (c) renin mRNA.
