Effect of water intake on serum aldosterone, plasma renin concentration, and arterial and urinary pH in wild-type mice
| Daily H2O Intake, ml | Serum Aldosterone Concentration, nM | Plasma Renin Concentration μg ANG I·ml sample−1·h−1 | Serum Osmolality, mosmol/kgH2O | Arterial pH | Arterial Pco2 | Arterial HCO3−, (calculated) mM | Urine pH | |
|---|---|---|---|---|---|---|---|---|
| High water intake | 9 | 1.57±0.36 (n = 3) | 0.40±0.02 (n = 3) | 306±(n = 4) | 7.37±0.01(n = 8) | 42±1 | 23±1 | 6.44±0.09 (n = 9) |
| Low water intake | 4 | 1.59±0.35 (n = 3) | 0.43±0.01 (n = 3) | 305±2 (n = 5) | 7.37±0.01 (n = 10) | 42±1 | 23±1 | 6.11±0.05*(n = 10) |
Values are means ± SE. Mice were given the grain-based diet(series 2).
