2. Efeito do plasma rico em plaquetas e da eritropoietina na regeneração do nervo ciático de ratos wistar
Injuries to the peripheral nervous system present a challenge for regenerative medicine. The study investigated the effects of platelet-rich plasma (PRP) and erythropoietin (EPO), alone or in combination, in the regeneration of peripheral nerve in rats. The work was developed in three phases using 70 rats. The first phase, evaluated the platelet concentratio

3. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

4. Células mononucleares autólogas de medula óssea na regeneração do nervo tibial em coelhos / Autologous mononuclear cells from bone marrow in the regeneration of tibial nerve in rabbits
The regeneration of peripheral nerves after injury has been target in researches for new technologies that lead to good results, so as to get completely restoration of nerve function. For such, many techniques have been developed using synthetic materials associated to exogenous factors that enhance the regeneration process, as mononuclear cells of bone marr

5. Emprego do colageno com organização supramolecular na regeneração nervosa periferica in vitro e in vivo / Influence of a naturally supraorganized collagen on the peripheral nerve regeneration in vitro and in vivo
The present study investigated in vitro and in vivo the influence of naturally supraorganized collagen on the peripheral nerve regeneration. In the in vitro study, Schwann cells (SCs) were seeded on naturally supraorganized collagen membranes and evaluated with immunocytochemistry and scanning electron microscopy. The results revealed that SCs kept the expre

6. Utilização de células-tronco autólogas de medula óssea na regeneração do nervo tibial de coelhos mediante técnica de tubulização com prótese de silicone / Applyng of autologous stem cells from bone marrow in the regeneration of tibial nerve of rabbits using the tubulization technique with silicone tube
Neste estudo é apresentado um modelo experimental de defeito agudo em nervo periférico para avaliação da regeneração nervosa mediante técnica de tubulização associada à inoculação de células-tronco autólogas de medula óssea. Foram utilizados 12 coelhos Nova Zelândia albinos, submetidos à secção bilateral e ao afastamento de 5mm do nervo ti

7. 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

8. Expression and localization of myogenic regulatory factors (MyoD and Myogenin) in somatic rat muscle after reinervation with vein graft tubulization / Expressão e localização de fatores regulatórios miogênicos (MyoD e Miogenina) em músculos somíticos de ratos reinervados pela técnica de tubulização
Peripheral nerve injuries can result in the loss of propioception, morphological and functional alterations of muscle fibers which causes a negative impact on the quality of life. These injuries elicit an alteration on the expression of muscle specific genes, like MyoD and Myogenin, involved in the satellite cell activation and muscle mass regulation. The ve

9. The reinnervation of extensor digitorius longus (EDL) of rats (Rattus norvegicus), would be influenciate by the association of adipose tissue and low power laser in tubulization technique by vein? / A reinervação do músculo extensor longo dos dedos (EDL) de ratos (rattus norvegicus) seria influenciada pelo uso do laser de baixa potência e do tecido adiposo na técnica de tubulização?
Lesões nervosas periféricas com alterações morfofuncionais são de grande importância clínica, porque pode prejudicar a função, comprometendo a sensibilidade e/ou a motricidade do órgão alvo. Quando o nervo é lesado, o indivíduo torna-se impossibilitado de realizar suas atividades, seja profissional ou pessoal, e a partir do acidente esta situaç

10. Estudo da ação das neuregulinas 1-alfa e 1-beta na regeneração nervosa. Estudo experimental em camundongos isogênicos (C57BL/6J) / Neuregulins 1-alpha e 1-beta on the regeneration the sciatic nerves of (C57BL/6J) isogenic mice using the tubulization technique
PURPOSE: To evaluate the effect of neuregulins 1-alpha and 1-beta on the regeneration the sciatic nerves of male adult C57BL/6J mice, using the tubulization technique. METHODS: Eighteen animals were used, divided into three groups. A polyethylene prosthesis was implanted in a 4.0 mm defect of the left sciatic nerve, as follows: group 1 containing only purifi

11. CÉLULAS TRONCO AUTÓLOGAS DE MEDULA ÓSSEA NA REGENERAÇÃO DO NERVO TIBIAL DE COELHOS MEDIANTE TÉCNICA DE TUBULIZAÇÃO COM PRÓTESE DE SILICONE / AUTOLOGOUS STEM CELLS FROM BONE MARROW IN THE REGENERATION OF TIBIAL NERVE OF RABBITS USING THE TUBULIZATION TECHNIQUE WITH SILICONE TUBE
This study presents an experimental model of an acute defect in a peripheral nerve to evaluate neural regeneration using a tubulization technique associated with the inoculation of autologous stem cells from bone marrow. A total of 12 New Zealand white rabbits underwent a bilateral dissection of the tibial nerve followed by repair with silicone tubulization.

N-acetylmuramyl-L-alanyl-D-isoglutamine (MDP) was evaluated for its effect on the regenerating peripheral neurons in adult animals. The left sciatic nerve of nine male adult mice C57BL/6J was cut, the proximal and distal nerve stumps were inserted into a polyethylene tube (PT) with 0,76 mm inner diameter, leaving a four mm distance gap. Animals were randomly
