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)

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.  (+info)

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.  (+info)

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.  (+info)

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.  (+info)

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.  (+info)

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)

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 ...
Anatomy Of Sciatic Nerve Anatomy sciatic nerve anatomy diagram sciatic nerve sensory distribution sciatic nerve piriformis anatomy sciatic nerve distribution sciatic nerve innervation Muscles are specialised tissues which assist the bones in locomotion. 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
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. 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 ...

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 ...

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 ...
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 ...
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 ...
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 ...
The sciatic nerve in the popliteal fossa is bordered superolaterally by the long head of the biceps femoris muscle and superomedially by the semimembranosus and semitendinosus muscles. The sciatic nerve branches into the common peroneal nerve and the tibial nerve at variable location along its course in the thigh. Popliteal sciatic nerve block is indicated for procedures in the foot and ankle ...
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 ...
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) ...
The five nerve roots come together to form a right and left sciatic nerve. On each side of your body, one sciatic nerve runs through your hips, buttocks and down a leg, ending just below the knee. The sciatic nerve then branches into other nerves, which continue down your leg and into your foot and toes ...
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. ...
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 ...
The aim of the present study was to examine inflammatory responses during Wallerian degeneration in rat peripheral nerve when the regrowth of axons was prevented by suturing. Transected rat sciatic nerve was sutured and ligated to prevent reinnervation. The samples were collected from the left sciatic nerve distally and proximally from the point of transection. The endoneurium was separated from the surrounding epi- and perineurium to examine the expression of cytokines in both of these compartments. Macrophage invasion into endoneurium was investigated and Schwann cell proliferation was followed as well as the expression of cytokines IL-1β, IL-10, IFN-γ and TNF-α mRNA. The samples were collected from 1 day up to 5 weeks after the primary operation. At days 1 to 3 after injury in the epi-/perineurium of the proximal and distal stump, a marked expression of the pro-inflammatory cytokines TNF-α and IL-1β and of the anti-inflammatory cytokine IL-10 was observed. Concurrently, numerous macrophages

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
Injury to the rat sciatic nerve leads to the induction of nerve growth factor (NGF) receptors on the denervated Schwann cells and their disappearance on the regenerating axons of the axotomized, normally NGF-sensitive sensory and sympathetic neurons. This disappearance in the axonal expression and r …
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 ...
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 ...
The sciatic nerve is the largest nerve in the body. It is a combination of smaller nerves (nerve roots) that join together and become the sciatic nerve. When the sciatic nerve is being compressed very specific symptoms in the legs arise. Pain, numbness, tingling and/or weakness in one leg are the most common signs of…
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 ...
Sciatica can be very painful and it can even be debilitating. This nerve condition is often caused by inflammation from your back pressing on the sciatic nerve. The pain can be so intense that pain relievers dont even help to control the pain. If you have this condition, you want to get sciatic nerve relief right away.. When you have sciatic nerve pain you really feel it. It can radiate down your entire leg and you can even feel it in your foot. The pain is intense and unrelenting. You usually feel it on just one side of your body. There are many conditions that can cause sciatica. It often happens when your spine compresses the nerve which will irritate it and cause problems and pain.. In many cases, the condition will improve in a few weeks with rest and exercises you can do at home. This isnt always the case however, and sometimes you need surgery to heal your back. If you have sciatica you know it because the pain is very intense. It can hurt from your lower back all the way into your ...

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. ...

Who ever thought that sitting would be a painful experience, but thats exactly what happens with those that suffers from sciatica.. Without this annoying and painful condition, sitting is normally a very relaxing thing to do, especially when you are watching a good movie or sporting event…. One of the most painful things that you can ever run into is known as sciatica, or the inflammation of the sciatic nerve. This condition sends shooting pain from your back all the way into your leg, and it can be a very scary thing. Sciatic nerve conditions can be almost debilitating, with the affected individuals having trouble with the most basic tasks in many instances. With that in mind, you have to be willing to get a little bit creative with their sciatic treatment. There are ways to relieve the pain temporarily and ways to get rid of the pain long term.. Surgery works….but not for everyone.. Though surgery is a good ...

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 ...

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 ...

MATERIAL AND METHODS: Forty adult male rats (250-300 g) were randomized into (1) collagen channel+CSF, (2) collagen channel+normal saline (NS), (3) autograft, and (4) sham surgery groups. The left sciatic nerve was exposed and a 10 mm nerve segment was cut and removed. In the collagen groups, the proximal and distal cuts ends of sciatic nerve were telescoped into the nerve guides and CSF or NS injected into collagen conduit. In the autograft group, the 10 mm nerve segment was turned backwards and used an autologous nerve graft. All animals were evaluated by sciatic functional index (SFI) and electrophysiology, histology, and immunohistochemistry ...
KISSIMMEE, Fla. -- Two minutes of pressure on the path of the sciatic nerve appears to bring up to an hours relief of pain and discomfort for people with a variety of symptoms.
The sciatic nerve is a nerve in the body that runs from the spinal cord down the leg and all the way down to the ankle. Occasionally, irritation of this nerve can occur and can actually cause some rather excruciating pain, or even a loss of movement in the affected leg. There are many causes of sciatic nerve pain including that caused from pregnancy. ...
Sciatica is a painful problem that is experienced by many people. The nerve root connecting to the sciatic nerve becomes irritated or compressed and causes a lot of pain and difficulty of movement of the leg or hip. The most common cause of sciatic nerve damage is lower back problems, such as occurs with a herniated disk, lumbar spinal stenosis, degenerative disc disease, and even from tumors or infections.HealingSciatic nerve damage will usually heal on its own within a few weeks, says Dr. Stephen Hochschuler of Spine Health.

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. ...
