Abstract

The aim of the present study was to investigate the synergism effect of Nerve growth factor(NGF) and monosiagangliosides (GM1) on dorsal root ganglion(DRG) and spinal cord neurons in sciatic nerve injured animal model. Ninety-six normal adult rats at the age of 6 months were randomly divided into 4 groups. NGF, GM1, NGF+GM1 and saline were given during and after operation and at 1w, 4w, and 8w after operation, following examination were processed: the number of neurons of DRG and anterior horn of spinal cord neurons were counted; the thickness of myelin sheath of regenerated nerve fibers of sciatic nerve was measured and the nerve conduction velocity (NCV) was measured.At 4w and 8w after operation, the morphology of neuron cells almost keep normal in the GM1 and NGF groups compared with that in injured group; The number of neurons was increased significantly in groups of NGF, GM1, NGF+GM1 than that in injured group; The thickness of myelin sheath of regenerated nerve fibers in sciatic nerve was increased significantly in groups of NGF, GM1, NGF+GM1 than that in injured group; The nerve conduction velocity (NCV) was increased significantly in groups of NGF, GM1, NGF+GM1 than that in injured group.NGF and GM1 had neuroprotective effects on neuronal normal structure and function of DRG and spinal cord neurons. The neuroprotective effects of NGF combined with GM1 were more effective than that NGF or GM1 applied alone.

Özet

Bu çalışmanın amacı siyatik sinir lezyonu olan sıçan modelinde sinir büyüme faktörü (NGF) ile monosiagangliosidlerin (GM1) dorsal kök ganglion (DRG) ve spinalkord nöronları üzerindeki sinerjetik etkilerini araştırmaktır. Doksan-altı normal erişkin sıçan 6 aylık iken randomize olarak 4 ayrı gruba ayrıldı. Operasyon sırasında ve 1h, 4h, ve 8h sonrasında NGF, GM1, NGF+GM1 ve salin solüsyonu uygulanan gruplarda DRG, ön zon spinal kord nöronları sayıldı, regenere olan siyatik sinir liflerinin miyelin kılıflarının kalınlıkları ve sinir iletim hızları (NCV) ölçüldü. Operasyondan 4 ve 8 hafta sonra GM1 ve NGF gruplarındaki nöron hücrelerinin morfolojileri hasarlı grup ile karşılaştırıldığında hemen hemen normal özellikte bulundu. NGF, GM1 ve kombine grupta nöron hücrelerinin sayısında kontrol gruba göre belirgin artış saptandı. NGF, GM1 ve kombine grupta regenere siyatik sinir myelin kılıfı kalınlıklarında yine kontrol grubuna gore önemli ölçüde artışlar saptandı. Sinir iletim hızlar ında da belirtilen her üç grupta da kontrol grubuna gore önemli artışlar kaydedildi. NGF ve GM1 nöronal normal yapı üzerinde DRG ve spinal kord nöronlarına nöroprotektif etkileri söz konusudur. Bu nöron koruyucu özellikleri birlikte kullanıldıklarında ayrı ayrı tek başına kullanılmalarına gore daha etkilidir.
