Cytochemical localization of the K+ regulation interface between blood and brain

Cytochemical localization of the K+ regulation interface between blood and brain

J A Firth. Experientia. .

Abstract

Phosphatase activity identified with Na+-K+-ATPase was localized at the basal surface of cerebral cortical capillary endothelium by perfusion with a p-nitrophenyl phosphate-strontium medium. The relationship of this to the blood-brain barrier to K+ is discussed.
