[Electron microscopic investigations on the neuroglia in a case of postnatal hypoxia (author's transl)].

The authors report a case of a six week-old infant, who has died from postnatal brian hypoxia. The ultrastructural investigation of the neuroglia shows lipid accumulations in most of astroglia cells, but only in a few oligodendrocytes. There is no correlation between glial metamorphosis and myelinization. Furthermore, there were found an immature neuropil, disturbed myelinization, and myelin and neuropil resorption processes. The study demonstrates the important role of hypoxic glial lesions n the evolution of the brain.
