We tested the ability of lithium (Li(+)) to block heat hyperalgesia, cold allodynia, mechanical allodynia and mechanical hyperalgesia in rats experimentally subjected to painful peripheral neuropathy. Chronic constrictive injury (CCI) to the sciatic nerve induced persistent hyperalgesia and allodynia. Intrathecal injection of Li(+) (2.5-40 micromol) into the region of lumbar enlargement dose-de...

Nerve Injury In article 2200227, Jingwei Xie and co-workers summarize the recent advances in microfluidic nerve injury models, which enable scientists to test various hypotheses regeneration mechanisms. Representative device designs techniques, such as vacuum-assisted axotomy, compression or tension-based physical injury, laser-based chemical are described discussed.

Abstract Background Stem cell transplantation has been reported as one of the promising strategies to treat retinal degenerative diseases. But, application and role retina stem cells (RSCs) in treatment patients with diseases have not fully revealed. This study aimed investigate potential embryo-derived RSCs into vitreous cavity repairing damaged mice. Methods were isolated from Kunming mice E1...

background suprascapular neuropathy (ssn) is generally thought of as a diagnosis of exclusion. however, increasing attention is being paid to the diagnosis, treatment and rehabilitation of this pathology to prevent chronic supraspinatus and infraspinatus atrophy in patients. to date, literature has only articulated variable or customized treatment and rehabilitation plans without clear standard...

Tumor necrosis factor-α plays important roles in immune system development, immune response regulation, and T-cell-mediated tissue injury. The present study assessed the net value of anti-tumor necrosis factor-α treatment in terms of functional recovery and inhibition of hypersensitivity after peripheral nerve crush injury. We created a right sciatic nerve crush injury model using a Sugita aneu...

The use of multiple loose ligations of the rat sciatic nerve has been proposed as a model for the study of allodynia and hyperalgesia. This pain hypersensitivity results from both an increase in the peripheral and central sensitization. The evidence indicating that the development of neuropathic thermal hyperalgesia and mechanical allodynia requires activation of spinal cord NMDA receptors. NMD...

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, i...

traffic accident has increased in the last decade. one of the most important outcomes of accident is spinal cord injury (sci). so, cell therapy is obtained a greater attention in most fields of medicine because of its potential for incurable diseases through replacing of dead cells. the current study aims to describe the important of locomotor functional and structural connection of the spinal ...

Tumor necrosis factor(TNF) appears as a key player at both central and peripheral terminals in early degenerative pathology and pain behavior after peripheral nerve injury. Recent studies suggest that TNF may be axonally transported and thereby contribute to these central and peripheral actions. To characterize this transport, we used a double ligation (DL) procedure that distinguishes between ...
