Changes in the external diameter of active arteries, excised from the rabbit ear, were recorded following jumps in pressure within the arteries. The arteries were either spontaneously active or were constricted with noradrenaline. Active arteries dil

1. The effect of sinusoidal internal pressures on the constriction of in vitro, pressurized segments of ear arteries from rabbits has been examined. All arteries were constricted against a static transmural pressure of 60 mmHg to 35-60% of maximal, u

Ouabain given intravenously to normal subjects in therapeutic doses (0·5 mg) had little effect on blood flow or venous tone in the forearm or hand. Comparable doses given into the brachial artery also had no consistent effect; much larger doses caus

1. Distensibility characteristics of the isolated, perfused rabbit ear artery were measured in the presence and absence of different concentrations of adrenaline. 2. The major effect of varying the adrenaline concentration was to vary the radius at w

Excised, pressurized segments of the rabbit ear artery have been used to examine the interaction between the transmural pressure and constriction of arteries by extraluminal noradrenaline. The bath temperature was kept at 32-33 degrees C to suppress

This isolated, perfused ear artery of the rabbit has been used to examine the effect of alterations in muscle load on the construction of arteries. The equilibrium muscle load, taken as the difference in wall stress between the relaxed and constricte
