OBJECTIVE: To determine the roles of axoplasmic transportation during regeneration after facial nerve injury.
METHOD: Facial nucleus injection and isotopic-label tracer with liquid scintillation counting techniques were used to investigate the changes of radioactivity after guinea pig facial nerve compressed.
RESULT: Axoplasmic transportation was observed again at 3 d after facial nerve injury, and the function recovered until 14 d. At 21 d after injury, it showed that transportation curve of radiolabeled protein was similar with that of the normal. There was particular curve in slow axoplasmic transportation that included two wave: W1 and W2. The axons regenerated at a rate of (2.84 +/- 0.12) mm/d in fast transportation while that of slow transportation is (3.16 +/- 0.08) mm/d.
CONCLUSION: It suggests that axoplasmic transport act as a important role during the course of facial nerve regeneration.
