Experiments were performed in seven conscious dogs to evaluate the contribution of total systemic autoregulation to the increase in mean arterial pressure (MAP) produced by the intravenous administration of pressor agents. Each dog was instrumented for the measurement of aortic pressure, central venous pressure, and cardiac output, and all dogs received(More)
Experiments were performed in nine conscious dogs to quantitate the contribution of systemic vascular autoregulation to the increases in total peripheral resistance (TPR) and mean arterial pressure (MAP) produced by angiotensin II (ANG II), arginine vasopressin (AVP), and norepinephrine (NE). We hypothesized that if autoregulatory vasoconstriction is(More)
Pressure diuresis is thought to be a major long-term regulator of arterial blood pressure (AP). Previously, pressure diuresis has been characterized using pharmacological or surgical blockade of other mechanisms known to affect renal function. This study evaluated pressure diuresis in conscious dogs with minimal experimental interference. Dogs were(More)
85SR was used for the local blood flow measurements in bones. A method for dynamic analysis of the magnitude of local blood flow based on 7-min analysis of the area under the logarithmic curve was presented. The radioactivity of the tibial diaphysis was followed by a gamma-scintillation dectector focused on the area of approximately 10 mm 0. The(More)
