Summary

In rabbits subjected to a 40 min abdominal aorta ligation and then reperfused 24 h, the calcium binding and ultrastructural changes in myelinated axons of the lumbosacral segments were visualized. To assess the calcium accumulation, the binding agent pyroantimonate was used.
Ultrastructural results show that the nodal axon membrane is very well suitable to calcium exchange, and that the intra-axonal and interlamellar calcium accumulation may by influence negate the axoplasmic neurofilaments and their participation in axoplasmic transport.

Key words: rabbit; spinal cord; myelinated fibres; calcium
