Renal response to amino acid infusion in essential hypertension.
In the present study, we evaluated the renal response to a 4-hour infusion of amino acids in essential hypertensive patients, as well as the effects that dietary sodium restriction and enalapril (a converting enzyme inhibitor) had on this renal response. During normal sodium intake, amino acid infusion significantly increased renal plasma flow from 383 +/- 58 to 478 +/- 51 mL/min and glomerular...
متن کاملRenal and endocrine response to saline infusion in essential hypertension.
To assess the contribution of the renin-angiotensin-aldosterone system and renal hemodynamics to acute renal sodium handling in essential hypertension we studied 21 subjects who had essential hypertension (16 with normal renin, 5 with low renin) and 9 normal subjects. All were in balance on a 10 mEq sodium intake before receiving a small sodium load, 60 mEq intravenously over 1 hour. Hypertensi...
متن کاملRenal Hypertension Produced by an Amino Acid
Acute renal hypertension is produced by the injection of the amino acid dopa (l-dihydroxyphenylalanine) into the partially or completely ischemic kidney of the cat. Evidence is presented suggesting that the rise in blood pressure following the injection of dopa is caused by its conversion into hydroxytyramine, a pressor amine. Kidneys with normal blood flow fail to transform dopa into a pressor...
متن کاملEssential amino acid supplementation in patients following total knee arthroplasty.
BACKGROUND By the year 2030, 3.48 million older U.S. adults are projected to undergo total knee arthroplasty (TKA). Following this surgery, considerable muscle atrophy occurs, resulting in decreased strength and impaired functional mobility. Essential amino acids (EAAs) have been shown to attenuate muscle loss during periods of reduced activity and may be beneficial for TKA patients. METHODS ...
متن کاملDifferential uric acid excretion in essential and renal hypertension.
ences were greatest in 11 patients with unilateral renal arterial stenosis and were derived from reduced uric acid excretion per unit of glomerular filtration rate by the ischemic kidney. Six patients with unilateral stenosis underwent surgery with subsequent cure of hypertension. Another patient, who did not have impaired ipsilateral uric acid excretion, failed to respond to nephrectomy. Succe...
