Enrichment Discrimination Behavior in Spontaneously Hypertensive Rats
Objectives: 1) To reveal, among spontaneously hypertensive rats, subpopulations that diverge in attention to objects enriching an empty cross-maze; 2) To evaluate effect of clinically efficient drug for treatment of attention deficiency atomoxetine on the attention to environmental cues in attentionally-low rats. Method: A novel paradigm that provides measure of attention towards enriching obje...

We have investigated whether differences seen in the pharmacological and morphological properties of mesenteric resistance vessels from spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) controls are also present in vessels from young SHR and WKY rats in which there is little difference in blood pressure (BP). Segments of small arteries (lumen diameter 150 ̂ m) were taken ...

The endothelium-dependent vascular relaxation to acetylcholine (ACh) in spontaneously hypertensive rats (SHR) may be impaired because of an imbalance of endothelium-derived relaxing factor and contracting factor. However, the role of the endothelium-dependent hyperpolarization remains undetermined. We examined the ACh-induced hyperpolarization and its contribution to relaxation in arteries of S...

Previous studies demonstrate that bilateral renal denervation enhances urinary sodium excretion and delays the onset of hypertension in young (7-week-old) spontaneously hypertensive rats (SHR) maintained on ordinary laboratory chow. We interpret these data as suggesting that increased renal nerve activity in this model contributes to hypertension by causing excess sodium retention. More recent ...

Intracellular calcium may be a mediator of insulin action in vascular smooth muscle cells. This study investigates effects of physiological concentrations of insulin on intracellular free calcium concentrations in primary unpassaged vascular smooth muscle cells derived from 3and 17-week-old normotensive rats (Wistar and Wistar-Kyoto) and spontaneously hypertensive rats (SHR). Underlying mechani...
