Sympathetic nervous system and glioma growth
European Journal of Cancer and Clinical Oncology, 1986C-6 glioma cells possess beta-adrenergic receptors on the cell surface. Activation of beta-adrenergic receptors with beta-adrenergic agonists increases intracellular levels of cAMP and leads to differentiation of C-6 glioma cells in vitro. The present study shows that growth of C-6 glioma tumor in rats with ablated sympathetic nervous system is ...

Sympathetic nervous system modulates macrophage function
International Journal of Immunopharmacology, 1992We have reported previously that sympathectomy augments immune responses in mice and rats. In the present study, we show that ablation of the sympathetic nervous system augments macrophage function as measured by increased TNF secretion. We also show that a factor present in the sympathetic ganglia of newborn rats, suppresses secretion of TNF by LPS ...

Peptides and the sympathetic nervous system
Pharmacological Research Communications, 1969Several workers have observed that under certain conditions kinins, although acting directly on blood vessels causing vasodilatation to produce hypotension, sometimes increase arterial blood pressure as well. Croxatto, Belmar, Pereda and Labacea (1962) reported such an effect when bradykinin was injected into rats with low blood pressure. These authors

Sympathetic nervous system response to intake
The American Journal of Clinical Nutrition, 1995Meals increase the activity of the sympathetic nervous system (SNS) above the activity level observed in the postabsorptive state. Pharmacologic blockade of the thermogenic effect of norepinephrine, the primary neurotransmitter of the SNS, suggests that this response accounts for approximately 20% of the thermic response to food.

The Sympathetic Nervous System in Hypertension
Clinical and Experimental Hypertension. Part A: Theory and Practice, 1984Sympathetic drive can contribute not only to the acute adjustment to circulatory stresses but also to sustained elevation in vascular resistance and arterial pressure. In hypertensive animals and humans excessive sympathetic activity coupled with a possible genetic factor may result in defects in electrogenic ion transport of vascular muscle or in ...

The Sympathetic Nervous System
2000Altered 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.
