The circadian rhythms of sodium (Na+), potassium (K+), aldosterone (ALDO), 11-deoxycorticosterone (DOC), 18-hydroxy-DOC (18-OH-DOC), cortisol (F), corticosterone (B), adrenaline (A), noradrenaline (NA), dopamine (DA), metanephrine (MN), normetanephrine (NMN), homovanillic acid (HVA), kallikrein (KE)
Membrane ion transports were investigated in lymphocytes from young normotensive and borderline hypertensive offspring with and without heredity for hypertension. Borderline hypertension per se was associated with an enhancement of sodium-potassium pump activity. Heredity per se was associated with
Most populations around the world consume less than the recommended levels of potassium. Long term low potassium intake could lead to decreased plasma potassium levels and induce hypokalemia. The increasing of plasma potassium levels 0,2-0,4 mmol/L by improving potassium intake decreased
The borderline hypertensive rat is the first filial offspring of the spontaneously hypertensive rat and the Wistar-Kyoto rat. With increased dietary sodium chloride intake, the borderline hypertensive rat develops hypertension and exaggerated cardiovascular and renal responses to acute environmental
Forty young subjects, aged 18 to 28 years, with mildly elevated blood pressure participated in a double-blind randomized three-period crossover study of the effect of sodium restriction with and without potassium supplementation on blood pressure. Dietary sodium intake was restricted for 18 weeks in
We evaluated the effect of a low potassium diet on blood pressure in normotensive (NT) and in borderline hypertensive subjects (BHT). There were 11 BHT men (age, 24.6 +/- 1.2 years) and 10 NT men (age, 23.5 +/- 1.0 years). Subjects were studied while on both low potassium, high sodium (30 meq/day,
The aim of this study was to investigate the effects of urinary sodium and sodium to potassium ratio on inflammatory cytokines, hypertension, and cardiovascular disease in patients with prehypertension. The authors observed 627 patients with prehypertension in the General Hospital of Shenyang
The relationship between dietary sodium and potassium intake with elevated blood pressure (BP) levels is unclear. The authors examined the association between dietary sodium and potassium intake and BP levels in 6985 adults aged 18 years and older with no prior history of hypertension who
We conducted a randomized, double-blind, placebo-controlled trial of oral potassium chloride supplementation (60 mmol/d) in 353 men and women with an initial average diastolic blood pressure between 80 and 89 mm Hg. In the active (n = 178) compared to the placebo (n = 175) treatment group, the
Blood pressure (BP), plasma electrolytes, renin, aldosterone, angiotensin II (AII) or catecholamines, the chronotropic effects of intravenous isoproterenol, norepinephrine (NE) or AII, the pressor responses to NE or AII, and the relationship between plasma AII and aldosterone concentrations were
BACKGROUND
High salt intake is linked to hypertension whereas a restriction of dietary salt lowers blood pressure (BP). Substituting potassium and/or magnesium salts for sodium chloride (NaCl) may enhance the feasibility of salt restriction and lower blood pressure beyond the sodium reduction alone.
1. The antihypertensive effect of a new beta-adrenoceptor blocking agent, trimepranol (10--14 mg/twice daily), chlorthalidone (50 mg every second day) and their combination was studied in eighteen patients with mild to moderate essential hypertension. In a controlled randomized cross-over study the
gly96/IEX 1 is a growth- and apoptosis-regulating, immediate early gene that is widely expressed in epithelial and vascular tissues. In vascular tissues, expression of the gene is induced by mechanical stretch, and overexpression of the gene prevents injury-induced vascular smooth muscle hypertrophy
