...Marie-Cecile Jacobs; David S. Goldstein; Jacques J. Willemsen; Paul Smits; Theo Thien; Jacques W. M. Lenders 1. Lower body negative pressure provides a means to examine neurocirculatory reflexive responses to decreases in venous return to the heart. We assessed whether the pattern...

... orthostatic stress induced by lower body negative pressure at –15 mmHg. 3. Variations in glycaemia markedly influenced plasma renin activity, which was increased at baseline during hyperglycaemia (3.82 ± 0.66 pmol of angiotensin I h −1 ml −1 compared with 2.13 ± 033 pmol of angiotensin I h −1 ml −1 during...

... functional significance. 2. The effects of noradrenaline infusion (2 μgh −1 kg −1 ) and lower body negative pressure (−27 mmHg) on renal haemodynamics, sodium excretion and tubular function were investigated in 25 renal transplant recipients and 10 normal subjects. Sixteen of the transplant recipients had...

... of atrial natriuretic factor, sodium nitroprusside and placebo. As a sympathetic stimulation test, the technique of the lower body negative pressure (–20 mmHg) was used. 2. Lower body negative pressure increased the forearm vascular resistance by +37 ± 8% during concomitant intra-arterial infusion...

... to progressively increasing lower body negative pressure until the onset of vasodepressor responses. 2. There was no significant difference ( P = 0.78) between the central hypovolemia tolerances of the cardiac transplant and the control groups. 3. The decrease in systolic blood pressure before the onset...
