... pressure is not linear and, furthermore, changes with the sympathetic tone. The present study tests the hypothesis that these factors lead to a redistribution of venous blood, which may impair the accuracy of the technique. The relative volume expansion rates of four leg segments were studied with the leg...

... these humoral and haemodynamic variables. Taken together these findings support the hypothesis that sympathetic tone to skeletal muscle is an important determinant of the concentration of plasma noradrenaline in blood. 19 11 1984 6 12 1984 © 1985 The Biochemical Society and the Medical Research...

... increased during steroid administration. 4. The mechanism underlying the increase in total peripheral resistance during long-term mineralocorticoid administration remains unclear. Increased sympathetic tone does not seem to be a factor since plasma noradrenaline decreased considerably. Pressor response...
