Indirect systolic and mean blood pressure determination by a new tail cuff method in spontaneously hypertensive rats.
A new tail cuff method for determining systolic and mean blood pressure in rats was developed based on photoelectric detection of tail arterial blood flow and pulsatile volume oscillation. Indirect systolic and mean blood pressure measured by this method correlated well with direct systolic and mean blood pressures recorded by a transducer and polygraph after carotid artery cannulation in strok...
متن کاملA simple versatile method for measuring tail cuff systolic blood pressure in conscious rats.
1. The non-invasive measurement of tail cuff systolic blood pressure in conscious rats is routinely used in long-term cardiovascular studies. There are a number of commercially available tail cuff systems, however, these apparatus are generally expensive and are dedicated for single-task operations. In the present study, a simple method for measuring systolic blood pressure, which requires only...
متن کاملValidation in awake rats of a tail-cuff method for measuring systolic pressure.
Bu~~AG, RUBEN D. Validation in awake rats of a tail-cuf method for measuring systolic pressure. J. Appl. Physiol. 34(2) : 279-282. 1973. -To determine why results of recent studies on applicability of the tail-cuff method to awake rats have been conflicting, arterial pressures were measured under various conditions. A Doppler ultrasonic flowmeter was used to detect blood flow changes occurring ...
متن کاملAmaranth Protein Hydrolysates Efficiently Reduce Systolic Blood Pressure in Spontaneously Hypertensive Rats.
Alcalase is the enzyme of choice to release antihypertensive peptides from amaranth proteins, but the hydrolysis conditions have not been optimized yet. Furthermore, in vivo assays are needed to confirm such a hypotensive effect. Our aim was to optimize the hydrolysis of amaranth protein with alcalase and to test in vivo the hypotensive effect of the hydrolysates. A response surface analysis wa...
متن کاملThromboxane synthesis and blood pressure in spontaneously hypertensive rats.
The present study examines effects of administration of OKY 046, an inhibitor of thromboxane synthesis, for 100 days on systemic blood pressure and renal function in spontaneously hypertensive rats and in normotensive control rats. Untreated spontaneously hypertensive rats had higher values for thromboxane excretion in the urine and higher values for blood pressure than did normotensive control...
