Urinary Excretion Rate of Guanidinoacetic Acid in Essential Hypertension

Urinary kallikrein excretion in children of parents with essential hypertension.

Twelve hour urinary kallikrein excretion was measured in 18 healthy children of parents with essential hypertension and in 47 healthy children of parents without this disorder. No statistically significant difference was observed between the two groups of children.

Urinary endothelin and sodium excretion in essential hypertension.

Erythrocyte 22Na efflux and urinary sodium excretion in essential hypertension.

1. The rate constant for total 22Na efflux from erythrocytes was examined in patients with mild to moderate hypertension and in normotensive controls. No difference in 22Na efflux rate constant was found when the cells from both groups were incubated in artificial medium. When the cells from both groups were incubated in their own plasma, the rate constant for Na efflux was significantly elevat...

Urinary kallikrein excretion in essential and mineralocorticoid hypertension.

Urinary kallikrein excretion has been reported to be decreased in patients with essential hypertension and elevated in patients with primary aldosteronism as a reflection of mineralocorticoid activity. Low renin essential hypertension (LREH) has been postulated to result from excess production of an unknown mineralocorticoid(s). Urinary kallikrein excretion was compared in outpatients with esse...

Urinary albumin excretion and atherosclerosis in essential hypertension.

1. Increased urinary albumin excretion is common in patients with essential hypertension and is at least to some extent correlated with prevailing blood pressure levels. However, the generalized vascular dysfunction present in advanced atherosclerotic disease may independently influence this parameter. 2. To evaluate this possibility, we assessed blood pressure, ultrasonographic carotid thickne...
