摘要: Areas containing AChE-positive capillaries were mapped in the brain of cat and guinea pig. Regions with mostly also contain neuronal elements AChE activity. Electron-microscopical cytochemistry revealed localization basement membranes endothelial cells pericytes very often continuity activity extracellular space. Intraendothelial was seen only pinocytic vesicles. The vascular is thought to be origin since no cytochemical evidence has been obtained for a synthesis this enzyme or other non-neuronal CNS.
