[Experimental study of peripheral nerve regeneration influenced inverted and non-inverted distal nerve segments].
The sciatic nerves of adult rats were sectioned bilaterally and the ends of the nerves were placed in silicone tubes. One side of the distal nerve segment was inverted and that of the contralateral side was non-inverted. After 2, 4, 6 weeks, the rats were killed and the specimens were removed for macroscopic, histologic and morphometric analysis. The results showed that either the inverted or non-inverted distal nerve segments had no influence on the number of the myelinated axons in the regenerated nerves, but the number and density of the myelinated axons was markedly diminished in the inverted distal nerve segments.
