The increases in caspase 3, 8-oxo-dG, Bad, Bax, and ratio of Bax\/Bcl-2 levels in the denervated muscle were attenuated by mitochondrial infusion, and the downregulation of Bcl-2 expression was prevented by mitochondrial infusion. In addition, the decrease in the expression of desmin and the acetylcholine receptor was counteracted by mitochondrial infusion; this effect paralleled the amount of distributed mitochondria. The restoration of the morphology of injured muscles and nerves was augmented by the local infusion of mitochondria. Mitochondrial infusion also led to improvements in sciatic functional indexes, compound muscle action potential amplitudes, and conduction latencies as well as the parameters of CatWalk (Noldus) gait analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>The local infusion of
