The profiles of BW and SBP in DSR and DSS rats. A NS + HF diet significantly increased BW in both DSR and DSS rats (A), but increased the SBP in only DSS rats (B). Olmesartan and hydralazine similarly decreased the SBP in NS + HF diet–fed DSS rats. BW, body weight. SBP, systolic blood pressure. NS, normal salt. HF, high fat. DSS rats, Dahl salt-sensitive rats. DSR rats, Dahl salt-resistant rats. *P < 0.05: NS/DSS rats vs. NS + HF/DSS rats, NS + HF/DSS rats + olmesartan or NS + HF/DSS rats + hydralazine. For clarity, asterisks have been removed from Fig. 1A.
