The Sympathetic Nervous System in Hypertension

2018
It has been clearly shown that adrenergic tone has a primary role in blood pressure control due to the regulatory effects on cardiac output and systemic vascular resistance. Several mechanisms, both at central and peripheral levels, participate in this control exerted by the sympathetic nervous system.

Antihypertensive Drugs and the Sympathetic Nervous System

Journal of Cardiovascular Pharmacology, 2007
Hypertension has been associated with several modifications in the function and regulation of the sympathetic nervous system (SNS). Although it is unclear whether this dysfunction is primary or secondary to the development of hypertension, these alterations are considered to play an important role in the evolution, maintenance, and development of ...

Immunoregulation mediated by the sympathetic nervous system, II

Cellular Immunology, 1979
Abstract The effect of acute immunization or continuous environmental antigenic exposure on nor-adrenaline (NA) content of rat lymphoid organs was studied. Immunization with sheep red blood cells resulted in a decrease in splenic NA content. In other experiments, NA levels were determined in lymphoid and nonlymphoid organs of SPF rats exposed to ...

The sympathetic nervous system and the metabolic syndrome

Journal of Hypertension, 2007
Studies performed in the past two decades have unequivocally shown that several of the components of the metabolic syndrome are associated with indirect and direct markers of adrenergic overdrive. This is the case for hypertension and obesity, in which resting tachycardia, elevated plasma norepinephrine values, increased sympathetic nerve traffic, as ...

Sympathetic Nervous System, Sleep, and Hypertension

Current Hypertension Reports, 2018

Sympathetic Nervous System and Hypertension

1974
The role of the sympathetic nervous system in the pathogenesis of essential human hypertension is not yet established [6, 7, 10, 11, 25, 36]. In spite of this the majority of drugs currently used in the treatment of human hypertension act by modifying peripheral and/or central adrenergic mechanisms [27].

Tumours of the Sympathetic Nervous System

1975
Neuroblastomas, ganglioneuromas and phaeochromocytomas are the three tumours of the sympathetic nervous system which arise from the same tissue in embryonic life and have the same anatomical sites. They vary in pathological anatomy but are similar in biochemistry. They differ in symptoms, diagnosis and therapy.

Essential hypertension and the sympathetic nervous system

Neurological Sciences, 2008
Sympathetic neural factors exert a key role in homeostatic blood pressure control. Evidence is available that abnormalities in sympathetic function may favour the development and progression of the hypertensive state. This paper will review the data collected throughout the years on the role of adrenergic mechanisms in the pathophysiology of the ...

The central sympathetic nervous system in hypertension

2013
The sympathetic nervous system participates in the development and progression of the essential hypertensive state, as shown by increased circulating plasma levels of the adrenergic neurotransmitter norepinephrine, elevated norepinephrine spillover rate, and augmented sympathetic nerve traffic discharge detected in the high blood pressure state.

The Sympathetic Nervous System

2000
Altered function of the sympathetic nervous system (SNS), whether caused by age per se or by age-associated disease, may contribute to impaired homeostasis in aging. The SNS occupies a central role in the maintenance of homeostasis because of its involvement in the regulation of many important physiologic functions.
