[Reactive changes and the phagocytic activity of the glial cells in pathological processes in the central nervous system].

This review deals with the current status of reactive changes and phagocytic activity in various types of glia in the CNS. Data from literature and partly our own findings on the reactive processes in oligodendrocytes, astrocytes, microgliocytes, and "multipotential glia" as well as their relationship with mesenchymal cells, particularly with those of hematogenous origin are given. Glial reactions both in pathological processes (Walter degeneration, trauma, etc) and in different functional states during the development of the central nervous system are considered.
