Abstract:

Excessive salt intake is considered a risk factor for the development of hypertension. Additionally, aberrant neurocirculatory responses to a cold stimulus are associated with an increased risk of hypertension. This study aimed to determine whether salt loading versus salt reduction would impact hemodynamic and sympathetic neural responses during the cold pressor test (CPT) in premenopausal women with a history of normal pregnancy. Nine healthy premenopausal women [42 ± 3 (SD) yr] were given a standardized isocaloric high-salt (HS; 250 mEq sodium/day) or low-salt (LS; 50 mEq sodium/day) diet f

Abstract:

Increased dietary salt in rats has been shown to sensitize central sympathetic circuits and enhance sympathetic responses to several stressors, including hyperinsulinemia, intracerebroventricular injection of angiotensin, and electrical stimulation of sciatic nerve afferents. These findings prompted us to test the hypothesis that increased dietary salt enhanced the exercise pressor reflex. Male Sprague-Dawley rats were fed 0.1% (low) or 4.0% (high) NaCl chow for 2 to 3 wk. On the day of the experiment, the rats were decerebrated, and the hind limb muscles were statically contracted for 30 s by

Abstract:

The prevailing theory of sodium depletion-induced salt appetite states that angiotensin (ANG) of cerebral origin, not of renal origin, causes the behavior. This assertion depends partly on an experiment that suppressed salt appetite using an intravenous infusion of a dose of angiotensin-converting enzyme (ACE) inhibitor (captopril, 2.5 mg/h) that supposedly blocked both central and peripheral enzyme (17). The present experiments used the same dose of captopril to suppress salt appetite both in 24-h and in 3-h models of sodium depletion-induced behavior. The captopril-infused rats 1) increased

The role of antidiuretic and pressor effects of vasopressin (VP) in deoxycorticosterone acetate (DOCA)-salt hypertension was studied in young and adult Brattleboro rats. The antidiuretic VP action was a necessary prerequisite for the development of severe DOCA-salt hypertension. The insufficient expansion of extracellular fluid volume in DOCA-salt-treated VP-deficient (DI) rats was associated with the attenuation of their hypertensive response, although they had highly increased blood volume and extracellular sodium.

Isolated rat lungs perfused with blood or plasma develop good hypoxic pressor reactivity, but those flushed of blood and perfused solely with physiological salt solution (PSS) show decreased or no hypoxic vasoconstriction. Because the handling of rats during collection of blood increases the plasma corticosterone levels, we wondered whether the difference between blood and PSS perfusion was due partly to higher glucocorticoid activity with blood than with PSS.

Abstract:

The role of calcitonin gene-related peptide (CGRP) in modulating hypoxic pulmonary vasoconstriction was assessed. The effects of CGRP and its antagonist [CGRP-(8–37)] on responses to acute hypoxia (3% O2) and angiotensin II (ANG II; 0.4 microgram) were studied in isolated lungs of male Sprague-Dawley rats perfused with a salt solution. Rats with pulmonary hypertension, induced by simulated altitude exposure, were also used to determine the actions of CGRP in a remodeled pulmonary vascular bed. In normotensive (NT) and altitude-exposed (AE) lungs, CGRP injections (10 nM), given after stable pre

Abstract:

Evidence exists implying multiple blood pressure quantitative trait loci (QTL) on rat chromosome 2. To examine this possibility, four congenic strains and nine substrains were developed with varying size chromosome segments introgressed from the spontaneously hypertensive rat (SHR/lj) and normotensive Wistar-Kyoto rat (WKY/lj) onto the reciprocal genetic background. Cardiovascular phenotyping was conducted with telemetry over extended periods during standard salt (0.7%) and high-salt (8%) diets. Our results are consistent with at least three independent pressor QTL: transfer of SHR/lj alleles

Abstract:

Amorphous to nanocrystalline ZrO2−3 wt. % Y2O3 powders were formed by chemical precipitation from mixed nitrate salt solutions. The powders were cold pressed and presintered in air for 2 to 6 h within the temperature range of 1100 °C and 1300 °C. Hot isostatic pressing was performed for 2 to 3 h within the temperature range of 1150 °C to 1350 °C in argon pressure of 150 MPa. Fully dense pellets with grain size of 22 nm to 45 nm were formed by application of low presintering temperatures.

Abstract:

Intracerebroventricular infusion of Na+-rich artificial cerebrospinal fluid (aCSF) causes larger sympathetic and pressor responses in Dahl salt-sensitive (S) than -resistant (R) or Wistar rats. Enhanced activity of the aldosterone-“ouabain” pathway or decreased nitric oxide (NO) release may contribute to this enhanced responsiveness. Where in the brain these mechanisms interact is largely unknown. The present study evaluated whether Na+ in the paraventricular nucleus (PVN) causes larger pressor responses in Dahl S (SS/Mcw) than R (Dahl SS.BN13) rats and whether mineralocorticoid receptors, ben

Insulin at doses of 10 or 100 units day−1 kg−1 was administered daily by subcutaneous injection to normal rats for 6 weeks. As it has been suggested that sodium retention plays a major role in the putative hypertensive activity of this hormone, insulin was also administered to saline- (1% NaCl) drinking rats according to the same protocol. Water- and saline-drinking rats served as controls. 3. After 6 weeks of insulin treatment, the mean arterial blood pressure did not increa

This study investigated the cardiovascular effects of the essential oil of Croton zehntneri (EOCZ) in deoxycorticosterone-acetate (DOCA)-salt hypertensive rats. Furthermore, in vitro experiments using isolated thoracic aortic rings were performed to assess the vascular effects of the EOCZ. In conscious hypertensive rats, intravenous (i.v.) injections of EOCZ (1–20 mg/kg) induced rapid (2–4 s) and dose-dependent hypotension and bradycardia (phase 1). The hypotension was followed by a significant pressor effect that was more evident at the higher doses (10 and 20 mg/kg) of EOCZ. Hypotension and

Environment-friendly membranes were fabricated from poly (lactic acid) (PLA) via the electrospinning technique. PLA is selected due to its biodegradability and thermoplastic. Firstly, the electrospinning parameters that affect the membrane structure and fibers morphology were identified. These include the polymer solution concentration, flow rate and salt additive. It was found that low concentration lead to smaller fiber size but with beads, and lower flow rates leading to thinner and uniform fibers, while salt additives limited the formation of beads.
