We evaluated sympathetic nervous system activity by sympathetic skin response (SSR) recording and we further investigated sympathetic and opioid outflow indirectly in patients with features of reflex sympathetic dystrophy by measuring concentrations of plasma catecholamines (CAs) and their metabolites and plasma metenkephalin (ME), before and after corticoid treatment. Six patients were studied...

SINCE the sympathetic nervous system has such a central place in homeostasis in general, and in circulatory adaptation in particular, it is paradoxical that so little is known about the possible contribution of disturbed sympathetic nervous function to the development of human diseases. Clinical tests of sympathetic nervous system activity have, by and large, been routinely applied in one setti...

The renin-angiotensin system plays an important role in the regulation of arterial blood pressure and in the development of some forms of clinical and experimental hypertension. It is an important blood pressure control system in its own right but also interacts extensively with other blood pressure control systems, including the sympathetic nervous system and the baroreceptor reflexes. Angiote...

Hypertonic saline solution can absorb part of the intracellular fluid volume into the extracellular space. The effects of this solution on the cardiovascular system are increased coronary flow and increased left ventricular contraction, without sympathetic system activation. This study was designed to assess the effects of hypertonic saline solution in open heart surgery and to compare it w...

Measurement of regional sympathetic activity in lean essential hypertension patients using electrophysiologic (sympathetic nerve recording) and neurochemical (measurement of norepinephrine spillover) techniques demonstrates activation of sympathetic outflow to the heart, kidneys, and skeletal muscle vasculature in younger (< 45 years) patients. The increase in sympathetic activity is a mechanis...
