title: Age-dependent increase in the non-specific cholinesterase activity of the capillaries in the rat neostriatum.
abstract: Histochemically demonstrable non-specific cholinesterase activity in the capillaries of the neostriatum of 3-5-month-old rats was much weaker than that of 24-27-month-old rats. In the young adult rats the activity was electron microscopically localized mainly in endoplasmic reticulum and perinuclear cisternae of the endothelial cells, while capillaries of old rats showed a positive reaction also in the basal lamina and outer cell membranes of glial processes.
