Arterial baroreflex regulation of regional vascular conductance at rest and during exercise

We tested the hypothesis that dynamic exercise resets the operating point and attenuates the spontaneous gain of the arterial baroreflex regulation of mesenteric and hindlimb vascular conductance in hypertensive rats. Eleven adult male spontaneously hypertensive rats were chronically instrumented wi...

Description
Summary:We tested the hypothesis that dynamic exercise resets the operating point and attenuates the spontaneous gain of the arterial baroreflex regulation of mesenteric and hindlimb vascular conductance in hypertensive rats. Eleven adult male spontaneously hypertensive rats were chronically instrumented with left carotid arterial catheters and Doppler ultrasonic flow probes around the superior mesenteric and left common iliac arteries.
