1. THE ACTION OF SERICIN PROTEIN ON INITIAL NERVE REPAIR, ASSOCIATED OR NOT WITH SWIMMING IN WISTAR RATS
RESUMO Objetivo: Analisar os efeitos do tratamento da sericina, associada ou não ao exercício de natação com sobrecarga, sobre o reparo inicial do nervo isquiático após compressão em ratos Wistar. Métodos: Foram separados 40 animais em cinco grupos, sendo eles: controle; lesão; lesão-sericina; lesão-natação e lesão-sericina-natação. Durante

2. Combination of heterologous fibrin sealant and bioengineered human embryonic stem cells to improve regeneration following autogenous sciatic nerve grafting repair
Abstract Background Peripheral nerve injury is a worldwide clinical problem, and the preferred surgical method for treating it is the end-to-end neurorrhaphy. When it is not possible due to a large nerve gap, autologous nerve grafting is used. However, these surgical techniques result in nerve regeneration at highly variable degrees. It is thus very importa

3. Comparative study between standard and inside-out vein graft techniques on sciatic nerve repair of rats. Muscular and functional analysis
Abstract Purpose: To compare the functional result of standart vein grafts and inside-out vein graft technique on sciatic nerve repair. Methods: We used 24 male Wistar rats divided into 4 groups: control group (CG), standard vein graft group (SVG), Inside-out vein graft group (IOVG) and denervated Group (DG). SVG, IOVG and DG underwent total section of th

4. N-acetylcysteine downregulates phosphorylated p-38 expression but does not reverse the increased superoxide anion levels in the spinal cord of rats with neuropathic pain
We determined the effect of N-acetylcysteine (NAC) on the expression of the phosphorylated p38 (p-p38) protein and superoxide anion generation (SAG), two important players in the processing of neuropathic pain, in the lumbosacral spinal cord of rats with chronic constriction injury (CCI)-induced neuropathic pain. The sciatic functional index (SFI) was also m

5. Combined polyglycolic acid tube and autografting versus autografting or polyglycolic acid tube alone. A comparative study of peripheral nerve regeneration in rats
PURPOSE: To compare sciatic nerve regeneration in rats using three different techniques of repair.METHODS:Fifteen isogonics rats were divided into three groups according to the method used to repair a 5-mm long defect created in the sciatic nerve: autogenous graft (Group A), polyglycolic acid tube (PGAt) (Group B), and of the association of PGAt with the gra

6. Evaluation of nerve regeneration in diabetic rats
PURPOSE: To compare sciatic nerve regeneration between non-diabetic (control) and streptozotocin-induced diabetic Wistar rats. METHODS:Four subgroups were evaluated. CN: Non-diabetic rats submitted to neurorrhaphy (n=9); DN: Diabetic rats submitted to neurorrhaphy (n=9); CG: Non-diabetic rats submitted to nerve grafting (n=10); DG: Diabetic rats submitted to

7. Thermographic evaluation of hind paw skin temperature and functional recovery of locomotion after sciatic nerve crush in rats
INTRODUCTION: Peripheral nerves are often damaged by direct mechanical injury, diseases, and tumors. The peripheral nerve injuries that result from these conditions can lead to a partial or complete loss of motor, sensory, and autonomic functions, which in turn are related to changes in skin temperature, in the involved segments of the body. The aim of this

8. Beneficial effects of treadmill training in experimental diabetic nerve regeneration
OBJECTIVES: We investigated the effects of treadmill training (10 weeks) on hindlimb motor function and nerve morphometric parameters in diabetic rats submitted to sciatic nerve crush. MATERIALS AND METHOD: Wistar rats (n = 64) were divided into the following groups: non-diabetic; trained non-diabetic; non-diabetic with sciatic nerve crush; trained non-diabe

9. Vein graft fulfilled with fat in peripheral nerve repair: a new proposal / Enxerto venoso preenchido com gordura no reparo de nervo periférico: uma nova proposta
With technology advance and the resultant production of more sophisticated equipment, microsurgery has been obtaining more attention in the experimental investigation field referred to peripheral nerves repair. It is know that in case of simple nerve section, without tissue loss, the end-to-side-neurorraphy is the most recommended technique. However, in each

10. Utilização de células mononucleares da medula óssea na regeneração do nervo ciático de ratos após neurorrafia
Peripheral nerves injuries are frequent and can result in permanent loss of function. Currently, cell therapy constitutes a great possibility of improving nerve regeneration, increasing the success of the nerve repair. Objective: To evaluate the use of mononuclear cells in the regeneration process of the sciatic nerve after its section and followed by end-to

11. Investigação da ação neuroprotetora do fator neurotrofico ciliar (CNTF) conjugado com peptideo contendo dominio de translocação de proteina (PTD) / Investigation of neuroprotective action of ciliary neurotrophic factor (CNTF) fused to a protein transduction domain (PTD)
Ciliary neurotrophic factor (CNTF) is known as a neuroprotective agent on motoneurons after peripheral nerve section in neonatal rats and adult mice. However, side effects like weight loss and caquexia have limited its clinical use. A promising approach for the avoidance of such side effects is the fusion of a protein transduction domain (PTD) with CNTF. Pre

12. The effects of low power laser irradiation on the regeneration of the common fibular nerve in rat submitted to a crush lesion. / Os efeitos da irradiação com laser de baixa potência na regeneração do nervo fibular comum do rato submetido a lesão por esmagamento
Peripheral nerve regeneration is a natural process, which requires a long period to complete, with a few evidences that physical agents including laser, can speed it up. The main objective of this investigation was to analyze the influence of low power laser (AsGaAL) irradiation on nerve regeneration, in a model of crush injury of the common fibular nerve of
