Differential Cardiovascular Responses in Wistar-Kyoto and Spontaneously Hypertensive Rats
With the use of a restraint stress paradigm, both normotensive Wistar-Kyoto (WKY ) rats and spontaneously hypertensive rats (SHR) underwent acute (1-hour restraint in a Perspex tube), chronic (1-hour restraint for 10 consecutive days), or no-restraint (control) stress. Rats experiencing chronic restraint were previously implanted with telemetric probes to measure heart rate and blood pressure. ...
متن کاملDiurnal cardiovascular patterns in spontaneously hypertensive and Wistar-Kyoto rats.
This study was designed to determine whether diurnal patterns of blood pressure, heart rate, or locomotor activity differed among two substrains of Wistar-Kyoto rats, derived originally from Charles River or Taconic Farms stock, or the spontaneously hypertensive rat. Cardiovascular parameters were continuously monitored over 24 hours. Resting systolic and diastolic blood pressure values were st...
متن کاملPartitioning of erythrocytes from spontaneously hypertensive and Wistar-Kyoto rats.
The charge-associated and non-charge-associated (probably lipid-related) surface properties of erythrocytes from spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY), from which SHR were originally derived, were studied by cell partitioning in dextran-polyethylene glycol aqueous phase systems. A major difference was found in the surface charge-associated and lipid-related propertie...
متن کاملIncreased Na+ and decreased Mg2+ intracellular concentrations in vascular smooth muscle cells from spontaneously hypertensive rats.
1. Although in blood cells decreased magnesium concentrations and increased sodium concentrations in essential hypertension have often been described, only sparse data exist on cellular magnesium or sodium content and exchange in vascular smooth muscle cells.2. Therefore in aortic smooth muscle cells from 10 spontaneously hypertensive rats (SHR) of the Münster strain and 10 normotensive Wistar-...
متن کاملImmunoreactive plasma concentrations of an endogenous antiopiate are higher in spontaneously hypertensive rats than in Wistar-Kyoto rats.
Tyrosine-MIF-1 (Tyr-Pro-Leu-Gly-NH2) is present in rat brain in varying concentrations throughout the day and can act as an opiate antagonist. Since altered sensitivity to pain is known to occur in hypertension, plasma and brain concentrations of Tyr-MIF-1--like immunoreactivity were measured in spontaneously hypertensive rats (SHR) and compared every 4 hours for 24 hours with the concentration...
