title: [The localization of the acetylcholinesterase in the area postrema and area subpostrema of the rat. Light and electron microscopical investigations (author's transl)].
abstract: In perfusion fixed material was studied the localization of acetylcholinesterase in the region of rat Area postrema on frozen slides and chopped tissue light and electron microscopically. In the light microscope there was a week reaction in the parenchyma cells of the Area postrema and the capillary endothelium and some nerve fibres of the Area subpostrema. Electron microscopically was demonstrated the AChE in the perinuclear cisterna, in the cisternae of the rough endoplasmatic reticulum and the neurotubuli of the axons and dendrites in the Area postrema. It was also evidenced the AChE-reaction in the pinocytic vesicles of the capillary endothelium, the axons, dendrites and some other structural elements of the neuropil in the Area subpostrema. The results were discussed from the standpoint of the functional morphology.
