1. Total fluid and saline intakes were greater in spontaneously hypertensive rats (SHR) than in normotensive rats (NTR). 2. Total fluid and saline intake were significantly elevated in prehypertensive SHR, 5 weeks old, compared with age-matched NTR, and the intakes fell with age in both strains but remained considerably greater in SHR. 3. In SHR, in which the blood pressure was maintained at normotensive levels by treatment with hydralazine, the saline and fluid intakes remained elevated above those of NTR. 4. SHR and NTR fed low sodium diet with water alone to drink have similar excretion rates of sodium, suggesting that their ability to conserve sodium was normal. 5. Measurement of sodium ..
