[The ultrastructure of accumulated mitochondria in injuries of demyelinated axons].
The authors ligated the nervus lienalis of the cat, and observed the subsequent accumulation of mitochondria in nonmyelinated axons in close vicinity proximal and distal to the ligature. In enlarged axons they found groups of mostly homogen population of mitochondria with specific morphologic signs. Concerning the mitochondrial ultrastructure authors arranged the mitochondria to three classes and five subclasses. The authors discuss the aim and function of mitochondrial accumulation in the injured nonmyelinated axon. Different directions of mitochondrial group's motion in axons was hypothetically assumed.
