Guanethidine-induced destruction of sympathetic postganglionic neurons in neonatal rats leads to transneuronal degeneration of the sympathetic preganglionic neurons. Using this model, we have been able to show a approximately 35% decrease in [3H]substance P ([3H]SP) binding in the intermediolateral cell column--suggesting that sympathetic preganglionic neurons possess substance P receptors. Our results show that [3H]substance P binding in the intermediolateral cell column is dependent on the integrity of sympathetic postganglionic neurons.

Substance P is an important element in pain perception. The sensory function of substance P is thought to be related to the transmission of pain information into the central nervous system. Substance P coexists with the excitatory neurotransmitter glutamate in primary afferents that respond to painful stimulation.[16] Substance P has been associated with the regulation of mood disorders, anxiety, stress,[17] reinforcement,[18] neurogenesis,[19] respiratory rhythm,[20] neurotoxicity, nausea and emesis,[21] pain, and nociception.[22] Substance P and other sensory neuropeptides can be released from the peripheral terminals of sensory nerve fibers in the skin, muscle, and joints. It is proposed that this release is involved in neurogenic inflammation, which is a local inflammatory response to certain types of infection or injury.[23] The regulatory function of SP also involves the regulation of its high-affinity receptor, NK-1. Substance P receptor antagonists may have important therapeutic applications in the treatment of a variety of stress-related illnesses, in addition to their potential as analgesics.

The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.
Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.

the clinical results of both surgical and neurolityc sympathectomy are uncertain
However, the clinical results of both surgical and neurolityc sympathectomy are uncertain. Indeed these procedures lead to a redistribution of the blood flow in the lower limbs from the muscle to the skin, with a concomitant fall of the regional resistance, mainly in undamaged vessels. The blood flow will be diverted into this part of the vascular tree, so that a "stealing" of the blood flow may occur.

Surgical and chemical sympathectomy can alter cellular proliferation
Surgical denervation and chemical sympathectomy can alter cellular proliferation, B- and T-cell responsiveness and lymphocyte migration in lymphoid organs [17]. In vitro studies have shown that neuropeptides can have numerous effects, either inhibiting or stimulating the proliferation, differentiation and functions of immune cells [19]*

Ablation of the sympathetic nervous system is a standard model for the study of sympathetic nervous system regulation of immune function
Ablation of the sympathetic nervous system by chemical sympathectomy is a standard model for the study of sympathetic nervous system regulation of immune function. We have previously documented that chemical denervation results in enhanced antigen-specific, but suppressed mitogen-induced, cytokine production by spleen cells. In our investigation into the mechanisms of sympathectomy-induced immune alterations, we first evaluated the peritoneal environment into which the protein antigen keyhole limpet hemocyanin is administered. Denervation resulted in increased production of tumor necrosis factor- by peritoneal exudate cells and these cells appeared to have enhanced antigen presenting capability. We hypothesized that nerve terminal destruction may be inducing an inflammatory response by monocyte/macrophages and other cell types throughout the periphery that could differentially alter subsequent mitogen versus antigen-specific responses. However, no evidence of sympathectomy-induced systemic or local splenic inflammatory responses was observed, as indicated by measuring the proinflammatory cytokines tumor necrosis factor- and interleukin-1. These experiments indicate that an inflammatory response is not likely to be responsible for sympathectomy-induced immune alterations, eliminating a potential confounding factor in interpreting sympathectomy studies.

cervical sympathectomy induced mast cell hyperplasia and increased histamine and serotonin content in the dura mater

Long-term superior cervical sympathectomy induces mast cell hyperplasia and increases histamine and serotonin content in the rat dura mater,

Mast cells are critical players in allergic reactions, but they have also been shown to be important in immunity and recently also in inflammatory diseases, especially asthma. Migraines are episodic, typically unilateral, throbbing headaches that occur more frequently in patients with allergy and asthma implying involvement of meningeal and/or brain mast cells. These mast cells are located perivascularly, in close association with neurons especially in the dura, where they can be activated following trigeminal nerve, as well as cervical or sphenopalatine ganglion stimulation. Neuropeptides such as calcitonin gene-related peptide (CGRP), hemokinin A, neurotensin (NT), pituitary adenylate cyclase activating peptide (PACAP), and substance P (SP) activate mast cells leading to secretion of vasoactive, proinflammatory, and neurosensitizing mediators, thereby contributing to migraine pathogenesis. Brain mast cells can also secrete proinflammatory and vasodilatory molecules such as interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF), selectively in response
to corticotropin-releasing hormone (CRH), a mediator of stress which is known to precipitate or exacerbate migraines. A better understanding of brain mast cell activation in migraines would be useful and could lead to several points of prophylactic intervention.

chronic interference with β-adrenergic receptors (via either sympathectomy or β-blockade) on cardiac mast cell morphology/activation and on interstitial collagen deposition
In the present study we investigated the effects of chronic interference with β-adrenergic receptors (via either sympathectomy or β-blockade) on cardiac mast cell morphology/activation and on interstitial collagen deposition. In rats subjected to chemical sympathectomizy with the neuro- toxin 6-hydroxydopamine (6-OHDA) we observed a significant increase of mast cell density, and in particular of degranulat- ing mast cells, suggesting a close relationship between the cardiac catecholaminergic system and mast cell activation. In parallel, chronic 6-OHDA treatment was associated with increased collagen deposition. The influence of the β-adren- ergic receptor component was investigated in rats subjected to chronic propranolol administration, that caused a further significant increase in mast cell activation associated with a lower extent of collagen deposition when compared to chem- ical sympathectomy. These data are the first demonstration of a close relationship between rat cardiac mast cell activation and the catecholaminergic system, with a complex interplay with cardiac collagen deposition. Specifically, abrogation of the cardiac sympathetic efferent drive by chemical sympathectomy causes mast cell activation and interstitial fibrosis, possibly due to the local effects of the neurotoxin 6-hydroxy- dopamine. In contrast, β-adrenergic blockade is associated with enhanced mast cell degranulation and a lower extent of collagen deposition in the normal myocardium. In conclusion, cardiac mast cell activation is influenced by β-adrenergic influences.

sympathetic denervation disturbed the patterns of gut immune-associated cell distribution
These findings indicated that sympathetic denervation disturbed the patterns of gut immune-associated cell distribution. It would substantiate the thesis of neuro-immune-endocrine and provide the new ideas for the intestinal disease prevention and drug developments.
