Crystalloid tubular arrays in sensory neurons after ischemia in the dog.

Crystalloid tubular arrays in the cytoplasm of canine sensory neurons were found after repeated 40 min aortic occlusion. The inclusions were composed of 35-40 nm tubules in parallel rows connected by fine side-arms. The tubular aggregates seem to be transient formations and were observed mostly in animals with 2-3 days of survival. After longer survival period (6 days) when signs of recovery in neurons were noticed, the crystalloids were not found.
