A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.
Disease or damage involving the SCIATIC NERVE, which divides into the PERONEAL NERVE and TIBIAL NERVE (see also PERONEAL NEUROPATHIES and TIBIAL NEUROPATHY). Clinical manifestations may include SCIATICA or pain localized to the hip, PARESIS or PARALYSIS of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. The sciatic nerve may be affected by trauma; ISCHEMIA; COLLAGEN DISEASES; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1363)
The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.
The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.
Nerve Compression Syndromes
The lipid-rich sheath surrounding AXONS in both the CENTRAL NERVOUS SYSTEMS and PERIPHERAL NERVOUS SYSTEM. The myelin sheath is an electrical insulator and allows faster and more energetically efficient conduction of impulses. The sheath is formed by the cell membranes of glial cells (SCHWANN CELLS in the peripheral and OLIGODENDROGLIA in the central nervous system). Deterioration of the sheath in DEMYELINATING DISEASES is a serious clinical problem.
Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.
Branch-like terminations of NERVE FIBERS, sensory or motor NEURONS. Endings of sensory neurons are the beginnings of afferent pathway to the CENTRAL NERVOUS SYSTEM. Endings of motor neurons are the terminals of axons at the muscle cells. Nerve endings which release neurotransmitters are called PRESYNAPTIC TERMINALS.
Nerve Growth Factors
Spinal Nerve Roots
Paired bundles of NERVE FIBERS entering and leaving the SPINAL CORD at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and PREGANGLIONIC AUTONOMIC FIBERS.
The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and SALIVARY GLANDS, and convey afferent information for TASTE from the anterior two-thirds of the TONGUE and for TOUCH from the EXTERNAL EAR.
Nerve Growth Factor
Peripheral Nervous System Diseases
Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
Nerve Fibers, Myelinated
A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the myelinated nerve fibers are completely encased in a MYELIN SHEATH. They are fibers of relatively large and varied diameters. Their NEURAL CONDUCTION rates are faster than those of the unmyelinated nerve fibers (NERVE FIBERS, UNMYELINATED). Myelinated nerve fibers are present in somatic and autonomic nerves.
Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy. (From Adams et al., Principles of Neurology, 6th ed, p1325)
A condition characterized by pain radiating from the back into the buttock and posterior/lateral aspects of the leg. Sciatica may be a manifestation of SCIATIC NEUROPATHY; RADICULOPATHY (involving the SPINAL NERVE ROOTS; L4, L5, S1, or S2, often associated with INTERVERTEBRAL DISK DISPLACEMENT); or lesions of the CAUDA EQUINA.
Peripheral Nervous System Neoplasms
Peripheral Nervous System
The nervous system outside of the brain and spinal cord. The peripheral nervous system has autonomic and somatic divisions. The autonomic nervous system includes the enteric, parasympathetic, and sympathetic subdivisions. The somatic nervous system includes the cranial and spinal nerves and their ganglia and the peripheral sensory receptors.
Piriformis Muscle Syndrome
The 5th and largest cranial nerve. The trigeminal nerve is a mixed motor and sensory nerve. The larger sensory part forms the ophthalmic, mandibular, and maxillary nerves which carry afferents sensitive to external or internal stimuli from the skin, muscles, and joints of the face and mouth and from the teeth. Most of these fibers originate from cells of the TRIGEMINAL GANGLION and project to the TRIGEMINAL NUCLEUS of the brain stem. The smaller motor part arises from the brain stem trigeminal motor nucleus and innervates the muscles of mastication.
Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.
A major nerve of the upper extremity. In humans the fibers of the radial nerve originate in the lower cervical and upper thoracic spinal cord (usually C5 to T1), travel via the posterior cord of the brachial plexus, and supply motor innervation to extensor muscles of the arm and cutaneous sensory fibers to extensor regions of the arm and hand.
Nerve Fibers, Unmyelinated
A class of nerve fibers as defined by their nerve sheath arrangement. The AXONS of the unmyelinated nerve fibers are small in diameter and usually several are surrounded by a single MYELIN SHEATH. They conduct low-velocity impulses, and represent the majority of peripheral sensory and autonomic fibers, but are also found in the BRAIN and SPINAL CORD.
A polyhydric alcohol with about half the sweetness of sucrose. Sorbitol occurs naturally and is also produced synthetically from glucose. It was formerly used as a diuretic and may still be used as a laxative and in irrigating solutions for some surgical procedures. It is also used in many manufacturing processes, as a pharmaceutical aid, and in several research applications.
Receptors, Nerve Growth Factor
A nervous tissue specific protein which is highly expressed in NEURONS during development and NERVE REGENERATION. It has been implicated in neurite outgrowth, long-term potentiation, SIGNAL TRANSDUCTION, and NEUROTRANSMITTER release. (From Neurotoxicology 1994;15(1):41-7) It is also a substrate of PROTEIN KINASE C.
Disease Models, Animal
Posterior Horn Cells
Neurons in the SPINAL CORD DORSAL HORN whose cell bodies and processes are confined entirely to the CENTRAL NERVOUS SYSTEM. They receive collateral or direct terminations of dorsal root fibers. They send their axons either directly to ANTERIOR HORN CELLS or to the WHITE MATTER ascending and descending longitudinal fibers.
Myelin P0 Protein
A protein that accounts for more than half of the peripheral nervous system myelin protein. The extracellular domain of this protein is believed to engage in adhesive interactions and thus hold the myelin membrane compact. It can behave as a homophilic adhesion molecule through interactions with its extracellular domains. (From J Cell Biol 1994;126(4):1089-97)
The major nerves supplying sympathetic innervation to the abdomen. The greater, lesser, and lowest (or smallest) splanchnic nerves are formed by preganglionic fibers from the spinal cord which pass through the paravertebral ganglia and then to the celiac ganglia and plexuses. The lumbar splanchnic nerves carry fibers which pass through the lumbar paravertebral ganglia to the mesenteric and hypogastric ganglia.
The 9th cranial nerve. The glossopharyngeal nerve is a mixed motor and sensory nerve; it conveys somatic and autonomic efferents as well as general, special, and visceral afferents. Among the connections are motor fibers to the stylopharyngeus muscle, parasympathetic fibers to the parotid glands, general and taste afferents from the posterior third of the tongue, the nasopharynx, and the palate, and afferents from baroreceptors and CHEMORECEPTOR CELLS of the carotid sinus.
Sympathetic Nervous System
The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.
Rats, Inbred Strains
Optic Nerve Injuries
Injuries to the optic nerve induced by a trauma to the face or head. These may occur with closed or penetrating injuries. Relatively minor compression of the superior aspect of orbit may also result in trauma to the optic nerve. Clinical manifestations may include visual loss, PAPILLEDEMA, and an afferent pupillary defect.
Type III intermediate filament proteins that assemble into neurofilaments, the major cytoskeletal element in nerve axons and dendrites. They consist of three distinct polypeptides, the neurofilament triplet. Types I, II, and IV intermediate filament proteins form other cytoskeletal elements such as keratins and lamins. It appears that the metabolism of neurofilaments is disturbed in Alzheimer's disease, as indicated by the presence of neurofilament epitopes in the neurofibrillary tangles, as well as by the severe reduction of the expression of the gene for the light neurofilament subunit of the neurofilament triplet in brains of Alzheimer's patients. (Can J Neurol Sci 1990 Aug;17(3):302)
Optic Nerve Diseases
Conditions which produce injury or dysfunction of the second cranial or optic nerve, which is generally considered a component of the central nervous system. Damage to optic nerve fibers may occur at or near their origin in the retina, at the optic disk, or in the nerve, optic chiasm, optic tract, or lateral geniculate nuclei. Clinical manifestations may include decreased visual acuity and contrast sensitivity, impaired color vision, and an afferent pupillary defect.
Diabetes Mellitus, Experimental
The 11th cranial nerve which originates from NEURONS in the MEDULLA and in the CERVICAL SPINAL CORD. It has a cranial root, which joins the VAGUS NERVE (10th cranial) and sends motor fibers to the muscles of the LARYNX, and a spinal root, which sends motor fibers to the TRAPEZIUS and the sternocleidomastoid muscles.
Neuritis, Autoimmune, Experimental
An experimental animal model for the demyelinating disease of GUILLAINE-BARRE SYNDROME. In the most frequently used protocol, animals are injected with a peripheral nerve tissue protein homogenate. After approximately 2 weeks the animals develop a neuropathy secondary to a T cell-mediated autoimmune response directed towards the MYELIN P2 PROTEIN in peripheral nerves. Pathologic findings include a perivascular accumulation of macrophages and T lymphocytes in the peripheral nervous system, similar to that seen in the Guillaine-Barre syndrome. (From Adams et al., Principles of Neurology, 6th ed, p1314; J Neuroimmunol 1998 Apr 1;84(1):40-52)
Nerve Sheath Neoplasms
Sensory Receptor Cells
Facial Nerve Injuries
Traumatic injuries to the facial nerve. This may result in FACIAL PARALYSIS, decreased lacrimation and salivation, and loss of taste sensation in the anterior tongue. The nerve may regenerate and reform its original pattern of innervation, or regenerate aberrantly, resulting in inappropriate lacrimation in response to gustatory stimuli (e.g., "crocodile tears") and other syndromes.
The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.
A local anesthetic that is chemically related to BUPIVACAINE but pharmacologically related to LIDOCAINE. It is indicated for infiltration, nerve block, and epidural anesthesia. Mepivacaine is effective topically only in large doses and therefore should not be used by this route. (From AMA Drug Evaluations, 1994, p168)
Cranial Nerve Neoplasms
Facial Nerve Diseases
Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle. The nerve may be involved intracranially, along its course through the petrous portion of the temporal bone, or along its extracranial course. Clinical manifestations include facial muscle weakness, loss of taste from the anterior tongue, hyperacusis, and decreased lacrimation.
Guided Tissue Regeneration
Procedures for enhancing and directing tissue repair and renewal processes, such as BONE REGENERATION; NERVE REGENERATION; etc. They involve surgically implanting growth conducive tracks or conduits (TISSUE SCAFFOLDING) at the damaged site to stimulate and control the location of cell repopulation. The tracks or conduits are made from synthetic and/or natural materials and may include support cells and induction factors for CELL GROWTH PROCESSES; or CELL MIGRATION.
Recurrent Laryngeal Nerve
Branches of the vagus (tenth cranial) nerve. The recurrent laryngeal nerves originate more caudally than the superior laryngeal nerves and follow different paths on the right and left sides. They carry efferents to all muscles of the larynx except the cricothyroid and carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.
Recovery of Function
Pathologic changes that occur in the axon and cell body of a neuron proximal to an axonal lesion. The process is characterized by central chromatolysis which features flattening and displacement of the nucleus, loss of Nissl bodies, and cellular edema. Central chromatolysis primarily occurs in lower motor neurons.
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)
Calcitonin Gene-Related Peptide
Calcitonin gene-related peptide. A 37-amino acid peptide derived from the calcitonin gene. It occurs as a result of alternative processing of mRNA from the calcitonin gene. The neuropeptide is widely distributed in neural tissue of the brain, gut, perivascular nerves, and other tissue. The peptide produces multiple biological effects and has both circulatory and neurotransmitter modes of action. In particular, it is a potent endogenous vasodilator.
An isomer of glucose that has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379) Inositol phospholipids are important in signal transduction.
Peripheral AFFERENT NEURONS which are sensitive to injuries or pain, usually caused by extreme thermal exposures, mechanical forces, or other noxious stimuli. Their cell bodies reside in the DORSAL ROOT GANGLIA. Their peripheral terminals (NERVE ENDINGS) innervate target tissues and transduce noxious stimuli via axons to the CENTRAL NERVOUS SYSTEM.
Abducens Nerve Diseases
Diseases of the sixth cranial (abducens) nerve or its nucleus in the pons. The nerve may be injured along its course in the pons, intracranially as it travels along the base of the brain, in the cavernous sinus, or at the level of superior orbital fissure or orbit. Dysfunction of the nerve causes lateral rectus muscle weakness, resulting in horizontal diplopia that is maximal when the affected eye is abducted and ESOTROPIA. Common conditions associated with nerve injury include INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; ISCHEMIA; and INFRATENTORIAL NEOPLASMS.
A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance.

Oculomotor Nerve Diseases
Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)
Gabapentin suppresses ectopic nerve discharges and reverses allodynia in neuropathic rats. (1/2173)Repetitive ectopic discharges from injured afferent nerves play an important role in initiation and maintenance of neuropathic pain. Gabapentin is effective for treatment of neuropathic pain but the sites and mechanisms of its antinociceptive actions remain uncertain. In the present study, we tested a hypothesis that therapeutic doses of gabapentin suppress ectopic afferent discharge activity generated from injured peripheral nerves. Mechanical allodynia, induced by partial ligation of the sciatic nerve in rats, was determined by application of von Frey filaments to the hindpaw. Single-unit afferent nerve activity was recorded proximal to the ligated sciatic nerve site. Intravenous gabapentin, in a range of 30 to 90 mg/kg, significantly attenuated allodynia in nerve-injured rats. Furthermore, gabapentin, in the same therapeutic dose range, dose-dependently inhibited the ectopic discharge activity of 15 injured sciatic afferent nerve fibers through an action on impulse generation. However, the conduction velocity and responses of 12 normal afferent fibers to mechanical stimulation were not affected by gabapentin. Therefore, this study provides electrophysiological evidence that gabapentin is capable of suppressing the ectopic discharge activity from injured peripheral nerves. This action may contribute, at least in part, to the antiallodynic effect of gabapentin on neuropathic pain. (+info)
Source of inappropriate receptive fields in cortical somatotopic maps from rats that sustained neonatal forelimb removal. (2/2173)Previously this laboratory demonstrated that forelimb removal at birth in rats results in the invasion of the cuneate nucleus by sciatic nerve axons and the development of cuneothalamic cells with receptive fields that include both the forelimb-stump and the hindlimb. However, unit-cluster recordings from primary somatosensory cortex (SI) of these animals revealed few sites in the forelimb-stump representation where responses to hindlimb stimulation also could be recorded. Recently we reported that hindlimb inputs to the SI forelimb-stump representation are suppressed functionally in neonatally amputated rats and that GABAergic inhibition is involved in this process. The present study was undertaken to assess the role that intracortical projections from the SI hindlimb representation may play in the functional reorganization of the SI forelimb-stump field in these animals. The SI forelimb-stump representation was mapped during gamma-aminobutyric acid (GABA)-receptor blockade, both before and after electrolytic destruction of the SI hindlimb representation. Analysis of eight amputated rats showed that 75.8% of 264 stump recording sites possessed hindlimb receptive fields before destruction of the SI hindlimb. After the lesions, significantly fewer sites (13.2% of 197) were responsive to hindlimb stimulation (P < 0.0001). Electrolytic destruction of the SI lower-jaw representation in four additional control rats with neonatal forelimb amputation did not significantly reduce the percentage of hindlimb-responsive sites in the SI stump field during GABA-receptor blockade (P = 0.98). Similar results were obtained from three manipulated rats in which the SI hindlimb representation was silenced temporarily with a local cobalt chloride injection. Analysis of response latencies to sciatic nerve stimulation in the hindlimb and forelimb-stump representations suggested that the intracortical pathway(s) mediating the hindlimb responses in the forelimb-stump field may be polysynaptic. The mean latency to sciatic nerve stimulation at responsive sites in the GABA-receptor blocked SI stump representation of neonatally amputated rats was significantly longer than that for recording sites in the hindlimb representation [26.3 +/- 8.1 (SD) ms vs. 10.8 +/- 2.4 ms, respectively, P < 0.0001]. These results suggest that hindlimb input to the SI forelimb-stump representation detected in GABA-blocked cortices of neonatally forelimb amputated rats originates primarily from the SI hindlimb representation.

Expression of alpha2-adrenergic receptors in rat primary afferent neurones after peripheral nerve injury or inflammation. (3/2173)1. Immunocytochemistry with polyclonal antibodies directed against specific fragments of intracellular loops of alpha2A- and alpha2C-adrenergic receptors (alpha2A-AR, alpha2C-AR) was used to explore the possibility that expression of these receptors in dorsal root ganglion (DRG) neurones of rat alters as a result of peripheral nerve injury or localized inflammation. 2. Small numbers of neurones with positive alpha2A-AR immunoreactivity (alpha2A-AR-IR) were detected in DRG from normal animals or contralateral to nerve lesions. In contrast, after complete or partial sciatic nerve transection the numbers of ipsilateral L4 and L5 DRG somata expressing alpha2A-AR-IR sharply increased (>5-fold). There was no discernible change in the number of DRG neurones exhibiting alpha2A-AR-IR innervating a region in association with localized chemically induced inflammation. 3. After nerve injury, double labelling with Fluoro-Gold, a marker of retrograde transport from transected fibres, or by immunoreactivity for c-jun protein, an indicator of injury and regeneration, suggested that many of the neurones expressing alpha2A-AR-IR were uninjured by the sciatic lesions. 4. In general the largest proportionate increase in numbers of neurones labelled by alpha2A-AR-IR after nerve lesions appeared in the medium-large diameter range (31-40 microm), a group principally composed of cell bodies of low threshold mechanoreceptors. The number of small diameter DRG neurones labelled by alpha2A-AR-IR, a category likely to include somata of nociceptors, also increased but proportionately less. 5. Relatively few DRG neurones exhibited alpha2C-AR-IR; this population did not appear to change after either nerve lesions or inflammation. 6. These observations are considered in relation to effects of nerve injury on excitation of primary afferent neurones by sympathetic activity or adrenergic agents, sympathetically related neuropathy and reports of sprouting of sympathetic fibres in DRG.

Hypothermic neuroprotection of peripheral nerve of rats from ischaemia-reperfusion injury. (4/2173)Although there is much information on experimental ischaemic neuropathy, there are only scant data on neuroprotection. We evaluated the effectiveness of hypothermia in protecting peripheral nerve from ischaemia-reperfusion injury using the model of experimental nerve ischaemia. Forty-eight male Sprague-Dawley rats were divided into six groups. We used a ligation-reperfusion model of nerve ischaemia where each of the supplying arteries to the sciatic-tibial nerves of the right hind limb was ligated and the ligatures were released after a predetermined period of ischaemia. The right hind limbs of one group (24 rats) were made ischaemic for 5 h and those of the other group (24 rats) for 3 h. Each group was further divided into three and the limbs were maintained at 37 degrees C (36 degrees C for 5 h of ischaemia) in one, 32 degrees C in the second and 28 degrees C in the third of these groups for the final 2 h of the ischaemic period and an additional 2 h of the reperfusion period. A behavioural score was recorded and nerve electrophysiology of motor and sensory nerves was undertaken 1 week after surgical procedures. At that time, entire sciatic-tibial nerves were harvested and fixed in situ. Four portions of each nerve were examined: proximal sciatic nerve, distal sciatic nerve, mid-tibial nerve and distal tibial nerve. To determine the degree of fibre degeneration, each section was studied by light microscopy, and we estimated an oedema index and a fibre degeneration index. The groups treated at 36-37 degrees C underwent marked fibre degeneration, associated with a reduction in action potential and impairment in behavioural score. The groups treated at 28 degrees C (for both 3 and 5 h) showed significantly less (P < 0.01; ANOVA, Bonferoni post hoc test) reperfusion injury for all indices (behavioural score, electrophysiology and neuropathology), and the groups treated at 32 degrees C had scores intermediate between the groups treated at 36-37 degrees C and 28 degrees C. Our results showed that cooling the limbs dramatically protects the peripheral nerve from ischaemia-reperfusion injury. (+info)
Injury-induced gelatinase and thrombin-like activities in regenerating and nonregenerating nervous systems. (5/2173)It is now widely accepted that injured nerves, like any other injured tissue, need assistance from their extracellular milieu in order to heal. We compared the postinjury activities of thrombin and gelatinases, two types of proteolytic activities known to be critically involved in tissue healing, in nonregenerative (rat optic nerve) and regenerative (fish optic nerve and rat sciatic nerve) neural tissue. Unlike gelatinases, whose induction pattern was comparable in all three nerves, thrombin-like activity differed clearly between regenerating and nonregenerating nervous systems. Postinjury levels of this latter activity seem to dictate whether it will display beneficial or detrimental effects on the capacity of the tissue for repair. The results of this study further highlight the fact that tissue repair and nerve regeneration are closely linked and that substances that are not unique to the nervous system, but participate in wound healing in general, are also crucial for regeneration or its failure in the nervous system.

A role for insulin-like growth factor-I in the regulation of Schwann cell survival. (6/2173)During postnatal development in the peripheral nerve, differentiating Schwann cells are susceptible to apoptotic death. Schwann cell apoptosis is regulated by axons and serves as one mechanism through which axon and Schwann cell numbers are correctly matched. This regulation is mediated in part by the provision of limiting axon-derived trophic molecules, although neuregulin-1 (NRG-1) is the only trophic factor shown to date to support Schwann cell survival. In this report, we identify insulin-like growth factor-I (IGF-I) as an additional trophin that can promote Schwann cell survival in vitro. We find that IGF-I, like NRG-1, can prevent the apoptotic death of postnatal rat Schwann cells cultured under conditions of serum withdrawal. Moreover, we show that differentiating Schwann cells in the rat sciatic nerve express both the IGF-I receptor (IGF-I R) and IGF-I throughout postnatal development. These results indicate that IGF-I is likely to control Schwann cell viability in the developing peripheral nerve and, together with other findings, raise the interesting possibility that such survival regulation may switch during postnatal development from an axon-dependent mechanism to an autocrine and/or paracrine one.

Krox-20 controls SCIP expression, cell cycle exit and susceptibility to apoptosis in developing myelinating Schwann cells. (7/2173)The transcription factors Krox-20 and SCIP each play important roles in the differentiation of Schwann cells. However, the genes encoding these two proteins exhibit distinct time courses of expression and yield distinct cellular phenotypes upon mutation. SCIP is expressed prior to the initial appearance of Krox-20, and is transient in both the myelinating and non-myelinating Schwann cell lineages; while in contrast, Krox-20 appears approximately 24 hours after SCIP and then only within the myelinating lineage, where its expression is stably maintained into adulthood. Similarly, differentiation of SCIP-/- Schwann cells appears to transiently stall at the promyelinating stage that precedes myelination, whereas Krox-20(-/-) cells are, by morphological criteria, arrested at this stage. These observations led us to examine SCIP regulation and Schwann cell phenotype in Krox-20 mouse mutants. We find that in Krox-20(-/-) Schwann cells, SCIP expression is converted from transient to sustained. We further observe that both Schwann cell proliferation and apoptosis, which are normal features of SCIP+ cells, are also markedly increased late in postnatal development in Krox-20 mutants relative to wild type, and that the levels of cell division and apoptosis are balanced to yield a stable number of Schwann cells within peripheral nerves. These data demonstrate that the loss of Krox-20 in myelinating Schwann cells arrests differentiation at the promyelinating stage, as assessed by SCIP expression, mitotic activity and susceptibility to apoptosis.

Sorbitol accumulation in rats kept on diabetic condition for short and prolonged periods. (8/2173)AIM: To study the influence of the course of diabetes, aging, and glycemia on the sorbitol accumulation in diabetic rats. METHODS: Streptozocin (Str) diabetic rats were obtained by Str i.v. (35 mg.kg-1). Glycemia and sorbitol levels from sciatic nerve and lens were measured after 1 d, 2, 5, and 8 months of diabetes. Sorbitol concentrations in serum, heart, diaphragm, small intestine, and kidney after 8 months of diabetes were measured. RESULTS: Diabetic rats after Str injection showed hyperglycemia (> 1.7 g.L-1), hyperphagia, polyuria, polydipsia, and loss of body weight. Sorbitol levels in lens and sciatic nerve increased in normal and diabetic rats; the increase was higher in diabetic rats. No relationship was shown between glycemia and sorbitol levels. An increased sorbitol level after 8 months of diabetes was found in small intestine and kidney. CONCLUSION: The sorbitol levels increased in lens and sciatic nerve with aging and this process was accelerated by diabetes. (+info)
Effect of acute and chronic administration of caffeine on pain-like behaviors in rats with partial sciatic nerve injury. |...
Caffeine, used in many pain medications as an adjuvant analgesic, is an adenosine A1 and A2A receptor antagonist. Here we examined the effects of acute or chronic caffeine administration in rats after partial sciatic nerve injury. The hindpaw response to mechanical or cold stimulation was assessed following photochemically induced sciatic nerve injury which leads to hypersensitivity to these stimuli. Caffeine was administered i.p. acutely or in the drinking water chronically. The mechanical and cold hypersensitivity of sciatic nerve-injured rats was dose-dependently alleviated by acute systemic administration of caffeine (10-80 mg/kg). The effect of caffeine was, however, associated with side effects including locomotor stimulation or depression. Chronic oral administration (average daily doses 27.5 mg/kg/day or 61.5 mg/kg/day for 2 weeks) of caffeine starting at the time of nerve injury did not significantly affect the development of pain-like behaviors. Thus, acute, but not long term, caffeine ...

Muscles are attached to the bones through tendons. Movement of limbs happens due to the contraction and relaxation of corresponding muscles present in that region. Joints help in the flexibility of bones, but a bone cannot be bent or stretched until a muscle acts on it. In other words, the muscles attached to that bone pulls it to the direction of movement.Explore of Anatomy and Physiology
Causes Of Sciatic Problems | Sciatic nerve pain
Reasons for sciatic nerve pain There are various causes that lead to sciatic nerve pain, but the major reasons that can lead to this type of pain are: 1. Excessive pressure on the sciatic nerve: Sciatic nerve pain can be a result of unwanted pressure put on the body due to improper posture, strain in the muscles, pregnancy, overweight, using a very soft mattress for sleeping purpose. It can also have excessive pressure on the sciatic nerve due to slip disc.

Objective- Comprehensive functional, histomorphometrical and immunohistochemical assessment of sciatic nerve regeneration through an inside-out vein graft in rat. Design- Experimental in vivo study.Animals- Fifty- four healthy male White Albino rats. Procedures- The rats were divided into three experimental groups (n=18), randomly: Sham operation (NC), Transected control (TC) and Inside-out vein graft (IOVG). In NC group after anesthesia the left sciatic nerve was exposed through a gluteal muscle incision and after careful homeostasis the muscle was sutured. In TC group the left sciatic nerve was exposed the same way, transected proximal to the tibio-peroneal bifurcation leaving a 10 mm gap. In IOVG group the left sciatic nerve was transected the same way and proximal and distal stumps were each inserted into an inside-out vein graft. Each group was further subdivided into three subgroups of six animals each and were studied 4, 8, 12 weeks after surgery.Results- Functional analysis showed ...
Sciatic nerve pain
There are various causes that lead to sciatic nerve pain, but the major reasons that can lead to this type of pain are: 1. Excessive pressure on the sciatic nerve: Sciatic nerve pain can be a result of unwanted pressure put on the body due to improper posture, strain in the muscles, pregnancy, overweight, using a very soft mattress for sleeping purpose. It can also have excessive pressure on the sciatic nerve due to slip disc. Some cases of sciatic nerve pain have been recorded by due to the compression of the sciatic nerve by a tumor encircling the spinal cord in the lower back. 2. Degenerative arthritis: It is also a common cause of sciatica. Degenerative arthritis also known as Osteoarthritis can be identified by certain specific characteristics like creation of bone spurs or a set of protruding bone which presses on the nerve roots. Older people sometimes may develop a medical condition called spinal stenosis, where the nerve is compressed due to narrowing of space in and around the spinal ...
Pressure of Local Anesthetic Solution While Performing Sciatic Nerve Blockade in Human Subgluteal Area
Intraneural introduction of local anesthetic belongs to the existing complications of peripheral nerves blockades. The damage of peripheral nerves is associated with the damaging effect of the injection needle and with the pressure caused by the introduction of local anesthetic. Purpose: Determine the pressure of the local anesthetic in fascial compartment of the sciatic nerve during his administration in the blockade of the sciatic nerve subgluteal access. Materials and Methods: Submitted blockade of the sciatic nerve subgluteal access in 22 patients with peripheral nerve electrostimulation under ultrasound guidance. To measure interstitial pressure system was used with the inclusion of a probe invasive blood pressure. Results: During the introduction of 1 ml in the fascial compartment of the sciatic nerve, the pressure of 0.77 psi (40 mmHg) was registered. In the course of the further introduction of local anesthetic up to 13 ml, the pressure did not alter validly (p > 0.05) and its average was 40 (35

TY - JOUR. T1 - Expression of genes encoding receptors for IgG (FcRIII) and for C3b/C4b (Crry) in rat sciatic nerve during development and Wallerian degeneration. AU - Vedeler, C. A.. AU - Conti, G.. AU - Bannerman, P.. AU - Pleasure, David E. PY - 1992. Y1 - 1992. N2 - Northern blots were used to examine the expression of genes encoding receptors for IgG (FcRIII) and for C3b/C4b (Crry) in rat sciatic nerve during development and Wallerian degeneration. Steady state levels of FcRIII (1.4 kb) and Crry (1.9 and 2.1 kb) mRNAs were higher in adult rat nerves than in 6 day and 21 day postnatal rat nerves, indicating that the expression of these receptors is developmentally regulated. The FcRIII and Crry cDNA probes also hybridized with total RNA from 3 day old rat Schwann cells and from adult rat peritoneal macrophages. The size of the FcRIII mRNA expressed by cultured Schwann cells (1.6 kb) differed from that expressed by peritoneal macrophages (1.4 kb); the two may be splice variants of one ...
Intraneural sciatic nerve pressures relative to the position of the hip and knee: a human cadaveric study | Read by QxMD
OBJECTIVES: To determine the effects of ipsilateral hip and knee position on intraneural sciatic nerve pressures.. DESIGN: Intraneural sciatic nerve pressures measured in intact, fresh cadaveric specimens relative to ipsilateral hip and knee positions.. LOCATION: Medical school anatomy laboratory.. SUBJECTS: Randomly acquired adult cadavers.. INTERVENTION: Pressure transducer placed within the sciatic nerve distal to the femoral attachment of the gluteus maximus. Intraneural pressures measured with the hip placed in 0, 45, and 90 degrees of flexion while the knee was positioned in 90, 45, and 0 degrees of flexion.. MAIN OUTCOME MEASUREMENTS: Tissue fluid pressures within the sciatic nerve relative to the position of the ipsilateral hip and knee. Tissue fluid pressure within the sciatic nerve exceeded previously defined critical thresholds for alteration of neural microcirculation and function. Although increased intraneural pressures were realized as the hip was positioned in greater flexion and ...
Ultrasound Guided Popliteal Fossa Block. Does Blockade Distal to Sciatic Nerve Bifurcation Speed Onset Time? A Prospective,...
Sciatic nerve block (SNB) has been shown to reduce postoperative pain and opioid requirements, as well as improve patient satisfaction after outpatient foot and ankle surgery. The sciatic nerve divides into two terminal branches (the common peroneal and tibial nerves) in the popliteal fossa. Through these two branches it innervates the entire leg, ankle and foot except for the skin over the anterior-medial aspect of the leg, which is supplied by the saphenous nerve, a branch of the femoral nerve.. Many approaches have been described to sciatic nerve blockade. High in the thigh or buttock are the classical posterior approach, the supine approach, and the anterior approach. In the popliteal fossa, a posterior, a lateral and a medial approach have been described. The popliteal fossa approaches are most commonly used to provide regional anesthesia and/or analgesia for major foot and ankle surgery.. Traditional nerve localization techniques include seeking paresthesiae on needle to nerve contact, or ...
If the sciatic nerve is afflicted, then treatment should be carried out immediately.
The second place where the sciatic nerve can still be subjected to sciatica is under the pear-shaped muscle. Such cases are not uncommon, if a person has excessive body weight and leads a sedentary lifestyle, that is, he simply sits the sciatic nerve. If there is an infringement of the sciatic nerve treatment is required immediately and under the supervision of a physician, that is, it must be treated as early as possible. Otherwise, compression-ischemic neuropathy of the sciatic nerve( also called infringement) can very quickly end with the death of nerve endings with limb paralysis. If, as a result of osteochondrosis of the lumbar spine, the sciatic nerve is affected by the symptoms, the treatment will be the same as for osteochondrosis. This, above all, the appointment of anti-inflammatory drugs, which should be selected only by a doctor and the maximum unloading of the damaged back. This is achieved by a horizontal position only on a solid surface without any deflections. That is, on the ...

Popliteal sciatic nerve block is indicated for procedures in the foot and ankle ...
Sciatic Nerve Pain : Sciatic Nerve Pain
Sciatica is a fairly common condition that refers to pain that originates in the sciatic nerve and often causes pain in the low back, buttocks, and down the leg. This can range from mild to severe, intermittent or constant, chronic or acute. Acute refers to the initial stages, and chronic refers to the later stages. The pain follows the path of the sciatic nerve from the low back down the leg, and more commonly affects only one side. Sciatica is not a condition in itself, but rather a set of symptoms that occur as a result of inflammation or irritation of the sciatic nerve - hence the term sciatica.. Sciatic nerve pain is very common and can affect people of all ages, however it is more prevalent as people reach their late thirties or beyond. It affects both men and women. When severe the pain can be quite crippling, making it difficult to walk, sit for long periods, go up stairs, or basically carry out a normal day. It can also be quite a nuisance at times. In the worst of cases, surgery may ...
Glatiramer Acetate Immune System Augmentation for Peripheral Nerve Regeneration in Rat Crushed Sciatic Nerve Model
Background: Protective antiself response to nervous system injury has been reported to be mediated by a T-cell subpopulation that can recognize self-antigens. Immune cells have been shown to play a role in the regulation of motor neuron survival after a peripheral nerve injury. The objective of the present study was to evaluate the effects of immune system augmentation with use of the antigen glatiramer acetate, which is known to affect T-cell immunity, on peripheral nerve regeneration. Methods: Wild-type and nude-type (T-cell-deficient) rats underwent crush injury of the sciatic nerve. Three and six weeks after the injury, the sciatic nerve was examined, both functionally (on the basis of footprint analysis and the tibialis anterior muscle response and weight) and histologically (on the basis of axon count). Results: Significantly greater muscle responses were measured after three weeks in the group of wild-type rats that were treated with glatiramer acetate (control limb:injured limb ratio, ...
Under anesthesia with ketamine-xylazine, the skin of the right lower limb was incised. The right sciatic nerve was exposed and ligated at mid-thigh level using surgical thread. For immunofluorescent analysis, operated mice were decapitated under deep anesthesia with ketamine-xylazine 8 h after ligation and perfused with 4% paraformaldehyde fixative in phosphate buffer, pH 7.4. The right sciatic nerve segment, including at least 5 mm both proximal and distal to the ligated site, was removed. The nonligated, left sciatic nerve was also taken out in the same manner as the right nerve. The removed nerves were placed into fixative for 4 h, transferred consecutively to 10, 15, and 20% sucrose in 0.01 m PBS, pH 7.4, for 4 h each at 4°C, mounted in Tissue-Tek OCT compound (Sakura, Tokyo, Japan), and frozen with powdered CO2 in acetone. Ten-micrometer-thick cryostat sections were prepared from the frozen tissues, blocked with normal goat serum (1:20), incubated with anti-synaptophysin (1:50,000; Dako) ...

ULTRASONOGRAPHIC ASSESSMENT OF THE CANINE SCIATIC NERVE - BENIGNI - 2007 - Veterinary Radiology & Ultrasound - Wiley Online...
To describe the ultrasonographic technique for investigation of the canine sciatic nerve, four canine cadaver pelvic limbs, two live healthy dogs, and five canine patients with suspected peripheral sciatic nerve lesions were examined with a high-resolution linear ultrasound transducer. The caudal part of the lumbosacral trunk and the origin of the sciatic nerve were visualized through the greater ischiatic foramen. The two components of the sciatic nerve, common peroneal and tibial nerves, were distinguished along the entire length of the nerve, until they branched at the level of the distal femur. In healthy live dogs they appeared as two adjacent hypoechoic tubular structures with internal echotexture of discontinuous hyperechoic bands, surrounded by a thin rim of highly echogenic tissue. The common peroneal component had a smaller diameter and was on the cranial aspect of the tibial component. An ultrasonographic lesion compatible with a peripheral nerve sheath tumor was found in one dog. ...
Examining the mechanical influences upon the sciatic nerve at the sciatic nerve-hamstring muscle interface during active and...
Background: Ultrasound imaging has been used to examine movement of the peripheral nervous system in response to normal body movements and therapeutic exercises, such as neural mobilisation. Researchers have clearly established that peripheral nerves must be able to move in relation to their surrounding interfacing tissues. However, to date the mechanical influences that these interfacing tissues have upon nerve movement has yet to be determined. Purpose: We sought to examine the different mechanical influences that the surrounding hamstring muscles have upon the sciatic nerve during lower limb movements. A better understanding of the mechanical influences imposed upon the sciatic nerve, from surrounding tissues, would be beneficial to then examine these relationships in clinical populations including lumbar-related leg pain. Methods: A cross-sectional, observational laboratory study was conducted in ten healthy participants (2 males, 8 females; age 24 ± 5 years (mean ± SD); height 169 ± 7 ...

A Computational Model for the Stimulation of Rat Sciatic Nerve Using a Transverse Intrafascicular Multichannel Electrode -...
Neuroprostheses based on electrical stimulation could potentially help disabled persons. They are based on neural interface that aim at creating an intimate contact with neural cells. The efficacy of neuroprostheses can be improved by increasing the selectivity of the neural interfaces used to stimulate specific subsets of cells. Selectivity is strongly influenced by interface design. Computer models can be useful for exploring the high dimensional space of design parameters with the aim to provide guidelines for the development of more efficient electrodes, with minimal animal use and optimization of manufacturing processes. The purpose of this study was to implement a realistic model of the performance of a transverse intrafascicular multichannel electrode (TIME) implanted into the rat sciatic nerve. A realistic finite element method (FEM) model was developed taking into account the anatomical and physiological features of the rat sciatic nerve. Electric potentials were calculated and interpolated

Increased protein kinase C (PKC) activity has been implicated in the pathogenesis of diabetic retinopathy and nephropathy. However, the role of PKC in diabetic neuropathy remains unclear. The present study was conducted to compare the effect of PKC inhibition by a PKC-beta-selective inhibitor, LY333531 (LY), on diabetic nerve dysfunction with that of an aldose reductase inhibitor, NZ-314 (NZ). Streptozotocin-induced diabetic rats were treated with or without LY and/or NZ for 4 weeks, and motor nerve conduction velocity (MNCV), coefficient of variation of R-R interval (CVR-R), sciatic nerve blood flow (SNBF), peak latencies of oscillatory potentials on electroretinogram, PKC activities in membranous and cytosolic fractions of sciatic nerves, and polyol contents in the tail nerves were measured. Untreated diabetic rats demonstrated delayed MNCV, decreased CVR-R, reduced SNBF, and prolonged peak latencies of oscillatory potentials. Treatment with LY as well as NZ prevented all these deficits in ...
Causes for sciatic nerve pain
This stretch may be a bit more difficult, and is most easily done lying down. Cross one foot on the opposite knee. Lie down on your back, and bend both of your knees. The Bonati Spine Procedures can provide immediate relief with sciatica treatment, especially if your symptoms of sciatic pain are related to a herniated or bulging lower lumbar intervertebral disc that is compressing one of the nerve roots before it joins the sciatic nerve. It can be caused either by an L3-L4 disk herniation, which is relatively rare, or by an L4-L5 disk herniation that happens to point out laterally into the nerve canal. False sciatica, by contrast, is caused by compression peripheral to the spinal nerve root. This symptom pattern tends to lead to the question of whether the whole sciatic nerve is being pinched somewhere along its course from the sacrum to the knee rather than one of the spinal nerves that leads into it. Again, this muscle follows along the sciatic nerve, and when tight, pulls on the pelvis which ...

Patterns of lipid changes with growth of chick sciatic nerve
Phospholipids and cerebrosides of the normal chick sciatic nerve were extracted by Folch procedures and separated with silica gel thin-layer chromatography using various chloroform-methanol solvents. The subsequent chemical assays were expressed as a function of the developmental stages of the chick from 15 days of incubation to 7 days after hatching (28 days from onset of incubation). A histological study of chick sciatic nerves at ages 18, 20, 22 and 25 days was conducted to identify the period of myelination. Luxol Fast Blue G stain was used to identify the myelin. Myelin, is poorly identified at 18 days but notably present at 25 days. The assays of the phospholipids, expressed as relative percent of the total phospholipid phosphorus, indicated that ethanolamine-phosphoglyceride ratio increases significantly from 17 days to 23 days from onset. Sphingomyelin ratio also increased during this time, but not as much. While the relative amount of serinephosphoglyceride remained constant and ...

4 Tips for Relieving Sciatic Nerve Pain | elistingz
2. Massage Therapy. Massaging on and around the affected area works just as well as over-the-counter pain relief medication for sciatica pain relief. Chiropractors can perform deep tissue massage to eliminate pressure around the sciatic nerve, as massaging soothes the tension built up in the muscles. 3. Good Posture Focusing on improving your posture regularly can, in the long-term, improve your experience with sciatica, and eliminate most of your pain. Most people with sciatic nerve pain do not realize that improper posture is largely responsible for their issues. Improper posture compromises the strength of the lower back muscles, making them weaker and more susceptible to sciatica. 4. Gentle Exercise. Aside from yoga stretches, other forms of gentle non-contact exercise can be helpful in the elimination of sciatic nerve pain. Lower back pain exercises are designed to re-strengthen the weakened lower back muscles and restore hip flexibility. ...

Functional Recovery after Peripheral Nerve Injury is Dependent on the Pro-Inflammatory Cytokines IL-1β and TNF: Implications...
The present study demonstrates that sciatic nerve injury induces a rapid production and release of IL-1β and TNF and causes infiltration of neutrophils and proinflammatory M1 monocytes/macrophages into the distal stump. Mice lacking both IL-1R1 and TNFR1 had reduced neutrophil and M1 macrophage influx and reduced nociceptive hypersensitivity compared with wild-type littermates after injury. However, recovery of sciatic nerve function was impaired in IL-1β-, TNF-, and IL-1β/TNF-ko mice. In addition, we found that neutrophil depletion, a strategy that alleviates neuropathic pain after sciatic nerve ligation, does not affect axonal regeneration and recovery of sciatic nerve function. Together, these results indicate that therapeutic approaches aimed at blocking neutrophil entry are likely to be more beneficial than neutralizing proinflammatory cytokines such as IL-1 and TNF in the treatment of neuropathic pain.. Activation of the innate immune response orchestrates a complex, tightly regulated ...

Mifepristone (RU 38486) influences expression of glycoprotein Po and morphological parameters at the level of rat sciatic nerve...
The observations here reported indicate that, in vivo, the expression of an important protein of peripheral myelin, the glycoprotein Po, is influenced by mifespristone (RU 38486), that is, an antagonist of progesterone (PR) and glucocorticoid (GR) receptor. In our experimental model, male rats have been treated at the first day of life with this antagonist and after repeated treatments, we have analyzed in the sciatic nerve of 20- (20d) and 30-day-old rats (30d) the mRNA and protein levels of Po. Moreover, expression of Po has also been analyzed in the sciatic nerve of animals treated during the first 30 days of postnatal life and then sacrificed at 90th day of life (90d). The results obtained have indicated that both mRNA and protein levels of Po decrease at 20d. Apparently, these effects seem to be transient because no changes are evident at the other two times of analysis. As shown by morphometric analysis, the treatment with RU 38486 is also able to induce morphological changes at the level ...
Expression of GLUTs in rat peripheral nerve was first studied at the mRNA level with Northern transfer analysis with cDNAs specific for GLUT1, GLUT2, GLUT3, and GLUT4. GLUT1 mRNA was the only GLUT mRNA detectable in rat sciatic nerve. In situ hybridization localized this mRNA to the perineurium and to some endo- and epineurial capillaries. Indirect immunofluorescence stainings demonstrated that GLUT1 protein epitopes were concentrated primarily in the perineurium and endoneurial capillaries. Also, some Schwann cells, a few epineurial capillaries, and medium-sized blood vessels showed a faintly positive immunoreaction. All cell types present in primary cultures initiated from rat sciatic nerve (perineurial cells, Schwann cells, and fibroblasts) expressed GLUT1 protein in vitro. Thus, Schwann cells, which expressed GLUT1 only occasionally at a low level in vivo, have the potential to express GLUT1 at a markedly higher level under cell culture conditions. Incubation of the cultures in 25 mM ...

Sciatic Nerve Pain And Upper Cervical Care - Natural Healing
Pelvic distortion is one of the major underlying causes of sciatic pain because when the pelvis is twisted or tilted, it places stress and pressure on the sciatic nerve and can cause pain, spasms, and inflammation in the area. When the upper vertebrae are corrected, the realignment not only corrects issues in the neck but also throughout the body. The hip no longer needs to compensate with twisting or tilting and the pressure lifts from the sciatic nerve. As a result, patients who undergo upper cervical treatment report having fewer episodes and less painful spasms.. If you or someone you know suffers from sciatic or chronic pain, reach out to us to schedule an upper cervical treatment to stop or reduce your pain. ...
