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 10

Time-dependent changes in systolic blood pressure (SBP) in Sham-operated normotensive (Sham) and hypertensive (H) rats treated with vehicle or Oryeongsan (ORS). Vehicle, 1 ml/rat/day, or ORS, 100 mg/kg/day orally, was administered for 3 weeks after 4 weeks of operation. Number of experiments: Sham + vehicle (S) or S + ORS, n = 8 for each group; hypertensive rats treated with vehicle (H-), n = 9; H + ORS, n = 8. versus Sham rats; ### versus H. Arrows indicate the start of the treatment.
