The present study investigates the effects of pregabalin (PGB) and codeine (COD) combination on neuropathic hyperalgesia in an animal model of peripheral nerve injury represented by partial sciatic nerve ligation. Hot plate and analgesimeter tests were performed to evaluate the influence of PGB, COD and their combination on thermal and mechanical hyperalgesia in the hind paw with partial sciati...

Metabotropic glutamate receptor 5 (mGluR5) protein increased after sciatic nerve section in ipsilateral L4 and L5 DRG neuronal profiles, with most of the increase occurring in myelinated A-fiber somata. mGluR5 also increased in lamina II of the ipsilateral spinal cord and the proximal sciatic nerve stump in this model. After L5 spinal nerve ligation, mGluR5 immunoreactivity increased dramatical...

Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...

After peripheral nerve injury, nociceptive afferents acquire an abnormal excitability to adrenergic agents, possibly due to an enhanced expression of α1-adrenoceptors (α1-ARs) on these nerve fibres. To investigate this in the present study, changes in α1-AR expression on nerve fibres in the skin and sciatic nerve trunk were assessed using immunohistochemistry in an animal model of neuropathic p...

BACKGROUND Developmental differences in responses to acute and chronic nerve injury have received minimal attention. This study examines developmental differences in behavioral responses to a proximal (closer to the spinal cord) (L5 and L6 spinal nerve root ligation) or to a more distal (closer to peripheral innervation) (partial sciatic nerve ligation) nerve injury in rats paralleling the infa...

The contemporary treatment of hamstring avulsions has been evolving, as more patients are being identified having persistently symptomatic partial tears recalcitrant to nonoperative treatment. endoscopic repair allows surgeons improved visualization the footprint, well safe dissection sciatic nerve. present technique article provides a step-by-step technical note allow for and effective surgica...

objective(s):  the aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (esm) tube conduit in comparison with autograft. materials and methods: thirty adult male rats (250-300 g) were randomized into (1) esm conduit, (2) autograft, and (3) sham surgery groups. the eggs submerged in 5% acetic acid. the decalcifying membranes were cut into four pie...

Objective(s) The role of Elaeagnus angustifolia fruit as an analgesic agent in acute pain has been proved earlier. In this study, the effects of aqueous extracts of three parts of this fruit (pericarp, medulla and seed) on chronic pain were investigated in mice. Materials and Methods A partial nerve injury was made using a tight ligature around the sciatic nerve, then doses (0.5, 1, 1.5 g/kg...
