[Ultrastructure of neurons and glial cells in the solitary tract nucleus and in the ventrolateral sections of the rat medulla oblongata after subdiaphragmatic vagotomy].
Using electron microscopy, complex remodelling of neuronal and glial cell ultrastructure was demonstrated in the solitary tract nucleus and ventrolateral medulla at different time intervals following bilateral subdiaphragmatic truncal vagotomy. Four weeks after vagotomy phagocytizing microgliocytes were demonstrated in the vicinity of nuclei of degenerating neurons within the rostral, but not the caudal, areas of solitary tract nucleus and ventrolateral medulla. It is suggested that the ultrastructural changes observed in the medulla after vagotomy depend on the distribution pattern of vagal projections to the caudal brainstem.
