Ultrastructural changes of the cat cerebral cortex within 30 60 minute recovery after anoxia






Tsitologiya 29(9): 1027-1031

Ultrastructural changes of the cat cerebral cortex within 30 60 minute recovery after anoxia

The ultrastructural changes in the cat sensorimotor cortex during 30-60 minute recovery after a 2.5-6 minute anoxia have been studied. The most prominent changes were hypertrophy of Golgi apparatus, reorganization of the neuronal endoplasmic reticulum (including the formation of lamellar bodies), increase of the number of lysosomes within nerve cell bodies, formation of deep invaginations of the neuronal cytoplasm into the nucleus, intensification of endocytosis and phagocytosis in the dendrites, appearance of the ultrastructural heterogeneity of the synapses (from normal synapses to depleted ones), normalization of ultrastructure of the part of mitochondrial pool. Glycogen granules were revealed in glial cell processes. The ultrastructural changes after a 6 minute anoxia followed by a 30-60 minute recovery were more expressed than after a 2.5 minute one.
