title: Abnormal whole-body and cellular (erythrocytes) turnover of 22Na+ in normotensive relatives of probands with established essential hypertension.
abstract: 1. Whole-body elimination rate of 22Na+ was decreased in normotensive or borderline first-degree relatives of hypertensive probands. 2. Whole-body potassium, exchangeable sodium and urine excretion of sodium, potassium and creatinine were similar in relatives and controls. 3. Erythrocyte net influx of 22Na+ was significantly increased in normotensive relatives. 4. Abnormal whole-body and cellular handling of sodium (22Na+) demonstrated in relatives indicates that this abnormality may have an important role in the development of essential hypertension in man.
