title: [Electron-cytochemical study of the localization of ATPase activity in the brain tissue of white rats].
abstract: A localization of ATPase activity in a rat's brain was studied by the lead method at the presence of Mg2+. The highest activity was noticed in the capillar basal layer, in nucleoli and nuclear chromatin. Less intensive sedimentation of precipitate was observed on the external nuclear membrane, granular cytoplasmic reticulum, ribosomes and in lipofuscin granules. Besides, the reaction product was observed on the cytomembrane of neurons, in synaptic slits and on the vesicles of some terminals. No ATPase activity was seen in mitochondria in the experimental conditions. Equal distribution of reaction product was seen in the cortex and hypothalamus.
