The location and local arrangement of motor, sensory neurons within brain stem, nodose ganglia, spinal ganglia and sympathetic ganglia projecting to rat's kidney and meridian point BL 23, GB 25 were investigated by HRP immunohistochemical methods following injection of 5% WGA-HRP into left kidney and meridian point BL 23, GB 25. Following injection of WGA-HRP into left kidney, anterogradely labelled sensory neurons were founded within either nodose ganglia and spinal ganglia. The sensory neurons innervating rat's left kidney were observed within spinal ganglia $T_{7}{\sim}L_3$. Sympathetic motor neurons innervating rat's left kidney were labelled within left suprarenal ganglia, either celiac ganglia, superior mesenteric ganglia, and sympathetic chain ganglia $T_{1}{\sim}L_3$. Sympathetic chain ganglia were concentrated in $T_{12}{\sim}L_1$. The sensory neurons innervating rat's meridian point BL 23 were founded within spinal ganglia $T_{2}{\sim}L_2$. They were numerous in spinal in ganglia $T_{10}{\sim}T_{12}$. Sympathetic motor neurons innervating rat's meridian point BL 23 were observed in suprarenal ganglia and greater splanchnic trunk, sympathetic chain ganglia from $T_1$ to $L_3$. They were concentrated in $T_{12}{\sim}L_3$. The sensory neurons innervating rat's meridian point GB 25 were labelled within spinal ganglia $T_{6}{\sim}T_{13}$. They were numerous in from T10 to $T_{12}$. Sympathetic motor neurons innervating rat's meridian point GB 25 were labelled within greater splanchnic trunk and sympathetic chain ganglia $T_{12}{\sim}L_3$. They were concentrated in $T_{13}{\sim}L_1$. This results neuroanatomically imply that the location of rat's motor and sensory neurons innervating meridian point BL 23 and GB 25 were closely related that of innervating kidney.

Objectives This scoping review aimed to suggest a Korean medicine approach by analyzing domestic and international clinical studies targeting the thoracic sympathetic ganglia. Methods This study was conducted based on Arksey and O'Malley's five steps and guided by the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews checklist and appendix. We searched seven electronic databases for studies on thoracic sympathetic ganglia reported untill August 23, 2023. The search terms used were 'thoracic sympathetic chain', 'thoracic paravertebral sympathetic ganglia', and 'thoracic paravertebral ganglion'. Results One hundred twenty-nine studies were finally selected. 90 papers were non-comparative studies (69.8%). The most common disease or symptom was hyperhidrosis (n=109, 66.9%), associated with the T1-7 levels of thoracic sympathetic ganglia (n=107, 65.6%). There were 17 studies (13.2%) of percutaneous approaches targeting the thoracic sympathetic ganglia, five studies (3.1%) targeting the mid-lower thoracic sympathetic ganglia. Conclusions This study broadly analyzed trends in domestic and international research targeting the thoracic sympathetic ganglia and attempted to propose a future Korean medicine approach. Further studies are needed.

Satellite glial cells (SGCs), a major type of glial cell in the autonomic ganglia, closely envelop the cell body and even the synaptic regions of a single neuron with a very narrow gap. This structurally unique organization suggests that autonomic neurons and SGCs may communicate reciprocally. Glial Ca²⁺ signaling is critical for controlling neural activity. Here, for the first time we identified the machinery of store-operated Ca²⁺ entry (SOCE) which is critical for cellular Ca²⁺ homeostasis in rat sympathetic ganglia under normal and pathological states. Quantitative realtime PCR and immunostaining analyses showed that Orai1 and stromal interaction molecules 1 (STIM1) proteins are the primary components of SOCE machinery in the sympathetic ganglia. When the internal Ca²⁺ stores were depleted in the absence of extracellular Ca²⁺, the number of plasmalemmal Orai1 puncta was increased in neurons and SGCs, suggesting activation of the Ca²⁺ entry channels. Intracellular Ca²⁺ imaging revealed that SOCE was present in SGCs and neurons; however, the magnitude of SOCE was much larger in the SGCs than in the neurons. The SOCE was significantly suppressed by GSK7975A, a selective Orai1 blocker, and Pyr6, a SOCE blocker. Lipopolysaccharide (LPS) upregulated the glial fibrillary acidic protein and Toll-like receptor 4 in the sympathetic ganglia. Importantly, LPS attenuated SOCE via downregulating Orai1 and STIM1 expression. In conclusion, sympathetic SGCs functionally express the SOCE machinery, which is indispensable for intracellular Ca²⁺ signaling. The SOCE is highly susceptible to inflammation, which may affect sympathetic neuronal activity and thereby autonomic output.

Major pelvic ganglia (MPG) in rats are an unique autonomic ganglia, containing both sympathetic and parasympathetic neurons related with the function of bladder, penis and bowel. It has been widely known that ionotropic $GABA_A$ receptors are the molecular target of $\gamma$-aminobutric acid (GABA), a major inhibitory neurotransmitter in central nervous system. However, their functions and regulations of $GABA_A$ receptors expressed in autonomic ganglia have been poorly understood. 1 examined the modulatory role of adenylyl cyclase (AC) and protein kinase A(PKA) on $GABA_A$-induced inward currents in the neurons of rat MPG. $GABA_A$ receptors were identified using immunofluorescent labeling in the rat major pelvic ganglion. Electrophysiological experiments were performed to record the activities of $GABA_A$ receptors. $GABA_A$ receptors were expressed only in sympathetic neurons. GABA induced marked inward currents in a concentration-dependent manner. Mucimol ($5{\mu}M$), a $GABA_A$ receptor agonist induced inward currents were significantly reduced in the presence of SQ 225361 $20{\mu}M$, a AC inhibitor and myristoylated PKA inhibitor 100 nM. In addition, forskolin ($1{\mu}M$), AC activator, augmented the GABA induced currents. The activation of AC/PKA-dependent pathway could involve in the regulation $GABA_A$ receptors, expressed only in sympathetic neurons of rat MPG. These findings are helpful for the better understanding the function of various pelvic organs innervated by MPG.

The purpose of this morphological studies was to investigate the relation between the meridian, acupoints and viscera using neuroanatomical tracers. The common locations of the spinal ganglia, sympathetic chain ganglia, spinal cord and brain projecting to the large intestine meridian were observed following injection of transganglionic tracer, WGA-HRP and transsynaptic neurotropic virus, pseudorabies virus(PRV), Bartha strain(Ba) and PRV-Ba-Gal (Galactosidase)) into the the large intestine(cecum, colon and rectum), ST37 and LI4. After survival times of 96 hours following injection into the thirty rats with WGA-HRP, PRV-Ba and PRV-Ba-Gal. They were perfused, and their spinal ganglia, sympathetic chain ganglia, spinal cord and brain were frozen sectioned($30{\mu}m$). These sections were stained by HRP and X-gal histochemical and PRV immunohistochemical staining method, and observed with a light microscope. The results were as follows : 1. WGA-HRP labeled neurons innervating the large intestine were observed bilaterally within the T13-L4 sympathetic chain ganglia, and T9-11 spinal ganglia. WGA-HRP labeled neurons innervating ST37 were observed within the L3-5 sympathetic chain ganglia, and L2-4 spinal ganglia. WGA-HRP labeled neurons innervating LI4 were observed in the middle cervical ganglion and stellate ganglion, and C5-8 spinal ganglia. 2. In spinal cord, PRV-Ba labeled neurons projecting to the large intestine, ST37 and LI4 were found in thoracic, lumbar and sacral spinal segments. Densely labeled areas of each spinal cord segment were founded in lamina N, V, VII(intermediolateral nucleus), Ⅸ, X and dorsal nucleus. 3. In medulla oblongata, PRV-Ba and PRV-Ba-Gal labeled neurons projecting to the large intestine, ST37 and LI4 were commonly found in the A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular nucleus, dorsal motor nucleus of vagus nerve, nucleus tractus solitarius, raphe obscurus nucleus, raphe pallidus nucleus, raphe magnus nucleus and gigantocellular nucleus. 4. In pons, PRV-Ba and PRV-Ba-Gal labeled neurons were commonly found in locus coeruleus, Kolliker-Fuse nucieus and A5 cell group. 5. In midbrain, PRV-Ba and PRV-Ba-Gal labeled neurons were commonly found in central gray matter. 6. In diencephalon, PRV-Ba and PRV-Ba-Gal labeled neurons were commonly found in paraventricular hypothalamic nucleus. These results suggest that PRV-Ba and PRV-Ba-Gal labeled common areas projecting to the large intestine may be correlated to that of the large intestine meridian, ST37 and LI4. Especially, These morphological results provide that interrelationship of meridian-acupoints -viscera may be related to the central autonomic pathways.

The purpose of this study was to determine whether percutaneous interferential current stimulation on thoracic sympathetic ganglia with amplitude modulated frequency (AMF) $90\~100$ bps and subthreshold of muscle contraction for 10 minutes on peripheral blood flow velocity in healthy subjects. Thirty-seven healthy volunteers were assigned randomly into an experimental group (n=25) and a control group (n=12). the experimental group received interferential current stimulation with subthreshold of the muscle contraction of current at AMF $90\~100$ bps on $1st\~5th$ thoracic sympathetic ganglial region for 10 minutes. The control group received same handling and electode placement, but no current was applied. Using a Doppler blood flow meter, the radial arterial blood flow velocities and the pulse raters were determined for two-way analysis of variance for repeated measures on time and group. There were no significant difference between the two groups with respect to the changes in arterial blood flow velocity and pulse rate over the four measurement times. Interferential current stimulation did not change in mean blood flow velocity and pulse rate. We conclude that interferential current stimulation on the thoracic sympathetic ganglia, as used in this study, did not dilate peripheral artery. This results suggests that interferential current stimulation dose not alter the activtiy of sympathetic nerve.

The development of the ganglia of the trachea was studied by electron microscopy in human fetuses ranging from 40 mm to 260 mm crown rump length. At 40 mm fetus, the tracheal ganglia was observed in the submucosa of the trachea. The primitive ganglia consisted of neuroblasts, undifferentiated cells, and unmyelinated nerve fibers. At 50 mm fetus, the neuroblast and their processes in the tracheal ganglia ware ensheathed by the bodies or processes of satellite cells. The cytoplasm of the neuroblast contained rough endoplasmic reticulum, mitochondria, Golgi complex, and ribosomes. At 70 mm fetus, cholinergic and adrenergic axon terminals were observed. Cholinergic axon terminals with agranular vesicles were abundant in the tracheal ganglia with increasing age. During next prenatal stage from 100 mm fetus, the ganglion cells and its processes were completely covered by a thin processes of the satellite cells. Unmyelinated nerve fibers were also completely ensheathed by processes of Schwann cell. Synaptic contacts between the cholinergic axon and dendrite of ganglion cells and a few dendrodendritic synapses were first observed at 100 mm fetus. The granule-containing cells were first identified in the tracheal ganglia at 200 mm fetus. These findings indicate that tracheal ganglia of human fetus resembles other parasympathetic and sympathetic ganglia, but not the enteric ganglia.

Background: The location and the number of lumbar sympathetic ganglia (LSG) vary between individuals. The aim of this study was to determine the appropriate level for a lumbar sympathetic ganglion block (LSGB), corresponding to the level at which the LSG principally aggregate. Methods: Seventy-four consecutive subjects, including 31 women and 31 men, underwent LSGB either on the left (n = 31) or the right side (n = 43). The primary site of needle entry was randomly selected at the L3 or L4 vertebra. A total of less than 1 ml of radio opaque dye with 4% lidocaine was injected, taking caution not to traverse beyond the level of one vertebral body. The procedure was considered responsive when the skin temperature increased by more than $1^{\circ}C$ within 5 minutes. Results: The median responsive level was significantly different between the left (lower third of the L4 body) and right (lower margin of the L3 body) sides (P = 0.021). However, there was no significant difference in the values between men and women. The overall median responsive level was the upper third of the L4 body. The mean responsive level did not correlate with height or BMI. There were no complications on short-term follow-up. Conclusions: Selection of the primary target in the left lower third of the L4 vertebral body and the right lower margin of the L3 vertebral body may reduce the number of needle insertions and the volume of agents used in conventional or neurolytic LSGB and radiofrequency thermocoagulation.
