Introduction Evidence is emerging that endogenous opioids play an important role in reflex cardiovascular control. In rats, intraventricular injection...

... subjects did not show a significant reduction in resting blood pressures until the fifth bout of exercise had been completed. 3. In the second experiment also, the competence of baroreflexes was assessed by measuring cardiovascular responses to lower body sub-atmospheric pressure (LBSP) 30 min before...

... in effective blood volume. 3. Baroreflex control of the sinus node was assessed from the pulse interval responses to rises (induced by methoxamine) or falls (induced by glyceryl trinitrate or sodium nitroprusside) in systemic arterial blood pressure. The relation between pulse interval and systolic blood...

... stopping diuretic therapy could result in an enhanced vascular response to noradrenaline, and a sensitive baroreflex could contribute to the control of blood pressure during diuretic treatment and buffers the return of high blood pressure when diuretics are stopped. 22 4 1982 2 9 1982 ©...

... baroreflex sensitivity as measured by various methods (phenylephrine, neck suction etc.). 5. It is concluded that blood pressure variability increases and heart rate variability decreases with age, but that changes in variability are not so obvious in hypertension. Also, differences in variability among...

... that the impairment of baroreflex function by levodopa is mediated, at least in part, at the periphery. In contrast, mechanisms operating within the central nervous system contribute to the lowering of blood pressure recorded in the horizontal position in patients receiving levodopa. 20 6 1972 © 1972...

...T. G. Pickering; B. Gribbin; D. O. Oliver 1. Serial studies of the baroreflex control of heart rate (baroreflex sensitivity) were made in thirty-two patients on long-term haemodialysis by relating the reflex slowing of the heart to the arterial pressure rise produced by repeated sudden injections...
