Effects of caffeine on plasma renin activity, catecholamines and blood pressure.

New England Journal of Medicine, 1978
Using a double-blind, randomized, cross-over protocol, we studied the effect of a single dose of oral caffeine on plasma renin activity, catecholamines and cardiovascular control in nine healthy, young, non-coffee drinkers maintained in sodium balance ...

The effect of weight reduction on blood pressure, plasma renin activity, and plasma aldosterone levels in obese patients.

New England Journal of Medicine, 1981
We investigated the relation between changes in the renin-aldosterone axis and reduction in blood pressure in 25 obese patients placed on a 12-week reducing diet; sodium intake was either medium (120 mmol) or low (40 mmol).

The effect of chronic adrenergic receptor blockade on plasma renin activity in man.

Journal of Clinical Endocrinology and Metabolism, 1972
The response of plasma renin activity (PRA) to the stimuli of upright posture and sodium deprivation was determined in three normal adults and in ten hypertensive patients before and after chronic alpha-adrenergic receptor blockade with phenoxybenzamine ...

Licorice-induced pseudoaldosteronism. Hypertension, hypokalemia, aldosteronopenia, and suppressed plasma renin activity.

Journal of the American Medical Association (JAMA), 1968
Hypertension, initially ncrmokalemic, was eventually associated with hypokalemia, alkalosis, suppressed plasma renin activity, and aldosteronopenia in a 58-year-old man who had ingested two to three 36-gm licorice candy bars daily for six years to seven ...

PLASMA RENIN ACTIVITY IN PRIMARY ALDOSTERONISM. IMPORTANCE IN DIFFERENTIAL DIAGNOSIS AND IN RESEARCH OF ESSENTIAL HYPERTENSION.

Journal of the American Medical Association (JAMA), 1964
DETAILED STUDIES, in the preceding communication (p 213), on three subsequently proved cases of primary aldosteronism indicate conclusively that in the presence of an aldosterone-secreting tumor, plasma renin activity is suppressed to zero, and it cannot

Plasma renin activity in the diagnosis of primary aldosteronism: failure to distinguish primary aldosteronism from essential hypertension.

Archives of Internal Medicine, 1969
Tests for demonstrating the responsiveness of plasma renin activity (PRA) have been simplified and their validity for the diagnosis of primary aldosteronism was examined.

Effect of hypoglycemia on plasma renin activity in dogs.

Endocrinology, 1970
Insulin-induced hypoglycemia was associated with a statistically significant increase in the renin activity of arterial plasma in anesthetized dogs. This increase was accompanied by an increase in the rate of secretion and the peripheral arterial plasma ...
