Venous plasma noradrenaline levels did not change during cooling after the 12 h fast, whilst after 48 h of fasting a significant increase in noradrenaline level was observed at the lowest suit temperature. 6. The results of this study provide...

...B. M. Frier; R. J. M. Corrall; J. L. Pritchard; P. S. Sever 1. The changes in blood glucose, plasma noradrenaline and plasma renin activity were measured in 11 normal subjects and in six tetraplegic subjects with a transection of the cervical spinal cord (preganglionic sympathectomy), in response...

...W. Kiowski; F. R. Bühler; P. Vanbrummelen; F. W. Amann 1. Plasma noradrenaline concentrations and blood pressure were measured in 45 patients with essential hypertension and 34 matched normotensive subjects. Plasma noradrenaline was similar in both groups, but in the hypertensive patients plasma...

Hypertensive patients with severe renal function disturbance showed significantly higher plasma noradrenaline concentrations and lower urinary noradrenaline excretion than the controls. 3. Noradrenaline clearance calculated by free plasma...

... as a control group. 2. Plasma noradrenaline concentration and plasma renin concentration at rest supine and after acute stimulation, as induced by frusemide intravenously and ambulation, did not differ from reference values in the 40-year-old normotensive controls. In the hypertensive group a close correlation...

...P. S. Sever; W. S. Peart; T. W. Meade; I. B. Davies; D. Gordon; R. D. G. Tunbridge 1. Plasma noradrenaline concentration and plasma renin activity were measured in a control, British, urban population ( n = 115) in which blacks were matched for age and sex with whites. 2. Similar measurements were...

...Y. Miura; K. Kobayashi; H. Sakuma; H. Tomioka; M. Adachi; K. Yoshinaga 1. Plasma noradrenaline concentrations and haemodynamic status were simultaneously studied in young patients with uncomplicated essential hypertension and in age-matched normal controls. 2. Resting plasma noradrenaline...

Hypertension was induced in rats by renal artery clip with the contralateral kidney removed (Goldblatt I) or left intact (Goldblatt II). 2. Plasma noradrenaline was increased 62% in the Goldblatt I animals...

...D. H. Jones; C. A. Hamilton; J. L. Reid 1. Mean supine plasma noradrenaline was lower in 12 male laboratory staff (0·24 ± 0·02 μg/l) than similarly normotensive out-patients (0·44 ± 0·07 μg/l). 2. In 164 non-medical hospital staff, plasma noradrenaline increased with age in white males only. 3...

...H. M. Brecht; W. Schoeppe 1. Plasma noradrenaline was measured in 125 patients with stable essential hypertension (WHO I—II) and in 107 normotensive control subjects lying and standing. 2. In normotensive subjects and in patients with essential hypertension no sex-related differences of plasma...
