Influence of a multideficient diet from northeastern Brazil on resting blood pressure and baroreflex sensitivity in conscious, freely moving rats.
The "regional basic diet" or RBD is a multideficient diet (providing 8% protein) which is known to produce dietary deficiencies in some populations in northeastern Brazil. The present study investigated the effects of RBD-induced malnutrition on resting blood pressure and baroreflex sensitivity in conscious rats. Malnourished rats were obtained by feeding dams the RBD during mating and pregnanc...
متن کاملPerindopril changes the mesenteric pressure profile of conscious hypertensive and normotensive rats.
Information about how antihypertensive therapy affects the arterial blood pressure profile in conscious animals is at present not available. Here we report measurements of part of the pressure profile in conscious spontaneously hypertensive rats (SHR, n = 7) and Wistar-Kyoto (WKY, n = 7) rats before and after treatment with the angiotensin-converting enzyme inhibitor perindopril. The previously...
متن کاملChronic measurement of left ventricular pressure in freely moving rats.
Measurements of left ventricular pressure (LVP) in conscious freely moving animals are uncommon, yet could offer considerable opportunity for understanding cardiovascular disease progression and treatment. The aim of this study was to develop surgical methods and validate the measurements of a new high-fidelity, solid-state pressure-sensor telemetry device for chronically measuring LVP and dP/d...

متن کاملA self-calibrating telemetry system for measurement of ventricular pressure-volume relations in conscious, freely moving rats.
Using Bluetooth wireless technology, we developed an implantable telemetry system for measurement of the left ventricular pressure-volume relation in conscious, freely moving rats. The telemetry system consisted of a pressure-conductance catheter (1.8-Fr) connected to a small (14-g) fully implantable signal transmitter. To make the system fully telemetric, calibrations such as blood resistivity...
