Nerve regeneration in synthetic and autogenous interfascicular grafts. II. Morphometric analysis

Cross-sectional areas at different levels, number of axons, maximal diameters, and number and maximal diameters of vessels were measured comparing autologous transplants with synthetic implants and nonlesion controls in a rat nerve regeneration model. The corresponding electrophysiologic data have been reported earlier in this journal. Although similar in many aspects, transplants led to the overall more reliable and slightly superior results, still lacking a substantial percentage of numerical qualities found in normal nerve, at least within the 3-month regeneration in this study.
