Fig. 7.

A: consecutive 24-h urine sodium (Na⁺) excretion rates (U_NaV) in response to systemic 5% dextrose in water (sD₅W) + renal interstitial (RI) D₅W (open bar, group 1), systemic angiotensin II (sANG II) + RI D₅W (solid bar, group 2), sANG II + RI scrambled (SCR) siRNA (shaded bar, group 3), and sANG II + RI ghrelin receptor (GR) siRNA (striped bar, group 4) infusions. Results are reported as μmol/min. B: cumulative Na⁺ balance values in response to sANG II + RI D₅W (solid bar, group 2), sANG II + RI SCR siRNA (shaded bar, group 3), and sANG II + RI GR siRNA (striped bar, group 4). All values were normalized to control sD₅W + RI D₅W values. Results are reported as mEq. Data represent means ± SE. Statistical analyses performed for values on day 1.
