Abstract

Aim: To explore the effect of nerve regeneration through repairing the defect of sciatic nerve in rats with the combination of optimized acellular allogeneic nerve and autologous neuroma. Material and Methods: 30 SD rats were randomly divided into two groups A and B, with 15 in each, which were used in preparing the models of the autologous neuroma and the defect of sciatic nerve. In the group A, the combination of allogeneic nerve and autologous neuroma was transplanted; in the group B, the autogenous nerve was transplanted. 15 Wistar rats were used to provide acellular allogeneic nerve, which came from the sciatic nerve in one side of the leg. The electrophysiology examination, the evaluation of sciatic nerve function index and the histological examination were done at the 8th weeks and the 16th weeks after the operation. Results: At the 8th week, the limb escape response appeared in all rats; at the16th week, there were many nerve fibers passing through the transplant in group A and group B. There was no significant difference in the number of the regenerated nerve fiber, diameter and the thickness of medullary sheath. At the 8th week, the conduction velocity of the regenerative nerve in group A were lower than that in group B (p<0.05), and there was no statistical difference in two groups at the 16th week; there was no significant deviation in the function index of sciatic nerve in group A and group B(P >0.05). Conclusion: The combination of allogeneic nerve and autologous neuroma, which repairs the defect of peripheral nerve, can promote the regeneration of nerve, and the function of nerve conduction can be recovered, which is a good substitute of nerve grafts.

Özet

Amaç: Hücresiz allojenik sinir ve otolog nöroma dokuları birleştirilip optimal hale getirilmiştir. Bu materyalin siyatik sinir defekti üzerine olan rejenere edici etkisi araştırılmıştır. Yöntem ve Gereç: Otuz sıçan rastgele olmak üzere A ve B grubu olarak ikiye ayrıldı. Her bir grupta 15 sıçan vardı. Grup A'daki sıçanlara hücresiz allojenik sinir ve otolog nöroma kombinasyonu nakledildi.Grup B'deki sıçanlara ise, otojenik sinir nakli yapıldı. Onbeş wistar rat hücresiz allojenik sinir sağlamak için kullanıldı. Bu doku, her bir sıçanın tek bir bacağının siyatik sinirinden elde edildi. İşlemden 8 ve 16 hafta sonra iki kez elektrofizyolojik muayene, siyatik sinir fonksiyon testi ve histolojik inceleme yapıldı. Bulgular: Sekizinci haftada tüm sıçanlarda alt uzuvlarda kaçınma refleksi görüldü. Onaltıncı haftada her iki gruptaki sıçanlarda sinir liflerinin geçiş yaptığı görüldü. Rejenerasyona giden sinir liflerinin sayısı, lif kalınlığı ve meduller kılıf açısından iki grup arasında farklılık görülmedi. Sekizinci haftada rejenere olan sinir liflerinde iletim hızı A grubunda B grubuna göre daha yavaştı (P 0.05). Sonuç: Periferik sinirlerdeki defektlerin onarımı için, allojenik sinir ve otolog nöroma birleşimi sinir rejenerasyonunu hızlandırır, sinir iletimini yeniden sağlar; bu nedenle: allojenik sinir ve otolog nöroma birleşimi sinir greftlerinin yerine kullanılabilecek iyi bir seçenektir.
