Heterogeneity of vascular smooth muscle alpha-adrenoceptors in canine blood vessels.

abstract：:1. We have examined the question asked in the title by studying: the carotid baroreceptor reflex in man with a variable-pressure neck chamber; the carotid baroreceptor reflex in conscious rabbits with a variable-pressure capsule around the carotid bifurcation; and the barorecptor-heart rate reflex. 2. At rest, the ass...

abstract：:1. It has previously been shown that perfusion with high O2-affinity-erythrocytes decreases venous PO2 (PVO2) and decreases O2 uptake (VO2) in contracting muscle at the same O2 delivery (arterial O2 concentration x flow). A linear VO2-PVO2 relationship has been obtained with a VO2-axis intercept, suggesting that, duri...
