Atrial natriuretic factor in NaCl-sensitive and NaCl-resistant spontaneously hypertensive rats.

Our previous studies demonstrated that chronic dietary NaCl supplementation is associated with significant increases in plasma atrial natriuretic factor in Wistar-Kyoto (WKY) rats but not in NaCl-sensitive spontaneously hypertensive rats (SHR-S). The current study tested the hypotheses that 1) acute volume-induced atrial natriuretic factor release is impaired in SHR-S compared with control NaCl...

Atrial natriuretic factor prevents NaCl-sensitive hypertension in spontaneously hypertensive rats.

Our previous studies demonstrated that acute infusion of atrial natriuretic factor (ANF) produces an enhanced depressor response in NaCl-sensitive spontaneously hypertensive rats (SHR-S) fed a high (8%) NaCl diet compared with control SHR-S fed a normal (1%) NaCl diet and that dietary NaCl loading increases circulating ANF levels in Wistar-Kyoto (WKY) rats but not in SHR-S. The current study te...

Impaired release of atrial natriuretic factor in NaCl-loaded spontaneously hypertensive rats.

Our previous studies demonstrated that NaCl-sensitive spontaneously hypertensive rats (SHR) of the Okamoto strain exhibit increased blood pressure and reduced noradrenergic input to the anterior hypothalamus area when fed high NaCl diets. The current study tested the hypotheses that 1) release of atrial natriuretic factor (ANF) into the plasma is impaired in NaCl-loaded SHR, a defect that would...

Excitatory sympathetic reflex in NaCl-sensitive spontaneously hypertensive rats.

We have previously demonstrated blunted reflex responses of lumbar sympathetic nerve activity during volume expansion in NaCl-sensitive spontaneously hypertensive rats maintained on basal (1% NaCl) diets compared with NaCl-resistant spontaneously hypertensive rats, Wistar-Kyoto rats, and Sprague-Dawley rats. The current study tested the hypothesis that chronic ingestion of a high (8%) NaCl diet...

High NaCl diet enhances arterial baroreceptor reflex in NaCl-sensitive spontaneously hypertensive rats.

Previous studies from our laboratory have shown that arterial baroreceptor reflex control of lumbar sympathetic nerve activity is blunted in the NaCl-sensitive spontaneously hypertensive rat (SHR-S) compared with either the NaCl-resistant spontaneously hypertensive rat (SHR-R) or the normotensive Wistar-Kyoto (WKY) rat. In the current study, the effect of dietary NaCl supplementation on arteria...
