Bueker (1948), investigating the effects of implanted tumors on the development of the nervous system of the chick embryo, found that sarcoma 180 caused enlargement (hypertrophy and hyperplasia) of the spinal ganglia in the segments adjacent to it. The motor columns, however, were not enlarged. He suggested that the sarcoma provided a selective periphery with mechanical and histochemical proper...

The innervation of the digestive tract, which is known to control a wide array of functions including smooth muscle contractility, splanchnic microcirculation, epithelial cell absorption/secretion and endocrine secretion, is composed of an intrinsic component consisting of neuronal cell bodies and nerve processes of the enteric neurons (i.e., the enteric nervous system) and an extrinsic compone...

Cardiac myocytes and the coronary circulation are innervated by both sympathetic and parasympathetic fibres which constitute the autonomic nervous system. 2 The autonomic outflow is controlled by regulatory centres in the midbrain, hypothalamus, pons, and medulla which integrate inputs from other brain areas as well as afferent stimuli from the periphery. The efferent signals follow descending ...

This study was performed to determine whether sympathetic stimulation reduces or redistributes cerebral blood flow. Total and regional cerebral blood flows were measured with the use of microspheres. Left stellate and superior cervical ganglia were stimulated electrically in anesthetized dogs. Sympathetic stimulation did not alter blood flow to ipsilateral cerebrum, cerebellum, or brainstem. Re...

Complex Regional Pain Syndrome (previously known as reflex sympathetic dystrophy, RSD) is a condition presenting with burning, nondermatomal pain associated with hyperhidrosis, intermittent oedema and discolouration and with evidence of mechanical and thermal allodynia. Conventional treatment is with sympathetic blockade produced by local anaesthetic injection around the appropriate sympathetic...

Functional recovery has been achieved in animal models of Parkinson’s disease by transplantation of the sympathetic ganglia, encouraging us to apply the graft therapy to patients with Parkinson’s disease/1/. In this situation, it is extremely important to maintain donor tissue in culture prior to grafting because in vitro culturing methods give an opportunity to manipulate donor tissue, thereby...

T H E sympathetic outflow to the head and neck and the greater part of that to the upper limbs passes on each side through the relatively small confines of the stellate ganglion and is here subject to interruption by stellate ganglion block. This block will cut off all efferent sympathetic impulses to the head and neck and most, if not all, of those to the upper limb and may be of value for exa...

Sympathetic hyperinnervation occurs in human ventricular tissue after myocardial infarction and may contribute to arrhythmias. Aberrant sympathetic sprouting is associated with elevated nerve growth factor (NGF) in many contexts, including ventricular hyperinnervation. However, it is unclear whether cardiomyocytes or other cell types are responsible for increased NGF synthesis. In this study, l...

Major nerve trunks that supply abdominal viscera contain axons of postganglionic neurons that originate in the coeliac ganglion, superior mesenteric ganglion, inferior mesenteric ganglia, hypogastric nerve ganglia and the sympathetic chain ganglia. Using the retrogradely transported neuronal marker Fast Blue, we mapped the distribution of labelled nerve cells after application of the dye to eit...
