DOCA-sodium hypertension in rats
1. A reduced noradrenaline turnover rate has been previously demonstrated in the brain stem of deoxycorticosterone acetate (D0CA)-sodium hypertensive rats. In the present study, the turnover rate was measured in smaller brain regions and the effect of sodium depletion was studied on the turnover rate of these regions. 2. Catecholamine turnover rate was significantly reduced only in the pons, wa...
متن کاملTubuloglomerular feedback in Dahl rats.
We have previously demonstrated a loss of autoregulation in Dahl salt-sensitive (Dahl-S) rats rendered hypertensive on a high-salt diet. To determine whether this was due to a decreased activity of either the myogenic or the tubuloglomerular feedback (TGF) response, we tested the TGF response in both Dahl-S and salt-resistant Dahl rats on high- and low-salt diets. TGF was investigated in the cl...
متن کاملMechanism of hypertriglyceridemia in Dahl rats.
Plasma triglyceride concentrations were shown to be higher in hypertensive (153 +/- 2 mm Hg) male Dahl salt-sensitive rats than in control Sprague-Dawley rats (122 +/- 2 mm Hg). These differences in triglyceride concentrations were seen when blood was drawn at 9 AM from unfasted animals (229 +/- 27 versus 111 +/- 8 mg/dL), at 1 PM after a 4-hour fast (186 +/- 13 versus 88 +/- 4 mg/dL), or at 9 ...
متن کاملCatecholamines in discrete kidney regions. Changes in salt-sensitive Dahl hypertensive rats.
Steady state levels of catecholamines (dopamine, norepinephrine, and epinephrine) were measured by the use of radioenzymatic techniques in discrete areas of the kidney (outer and inner cortex, outer and inner medulla) dissected by a "punch" technique from frozen kidney sections of salt-sensitive (DS) and salt-resistant (DR) Dahl rats fed a low or high salt diet. All three catecholamines were pr...
متن کاملThe physiological changes of cumulative hemorrhagic shock in conscious rats.
Hemorrhagic shock is a common cause of death in emergency rooms. Current animal models of hemorrhage encounter a major problem that the volume and the rate of blood loss cannot be controlled. In addition, the use of anesthesia obscures physiological responses. Our experiments were designed to establish an animal model based on the clinical situation for studying hemorrhagic shock. Hemorrhagic s...
