Abstract:
This paper aims to study the recovery function of two drugs combination on rat sciatic nerve injury regeneration model. Sixty rats were divided into groups randomly and averagely. All animals after dividing left sciatic nerve were given epineurium-interrupted suture for constructing peripheral nerve injury model. Muscle on operation side in medication administration team was injected 0.5 ml drug while the contract group was given equal amount of normal saline. Sciatic nerve function evaluation and nerve electrophysiology index detection were conducted after operation at fixed period. We drew materials for morphological observation 12 weeks after operation. The results showed that group with independent administration of nerve growth factor (NGF) and nimodipine (ND) in large dose was superior than group in small dose in nerve electro physiology index (P<0.05) and group with combination administration of NGF and ND in large dose was also superior than group in small dose (P<0.05). In addition, regeneration effect of combination administration group was better than that of independent administration group when using same dose. The larger the dose was, the better the effect was. We can conclude that two-drug combination can promote recovery function on rat sciatic nerve injury regeneration model.
