title: [Dynamics of the distribution of labeled etimizol in brain cell structures].
abstract: The time course of 14C-etimizol distribution in cell structures of the rat cerebral cortex was studied. Two minutes after intraperitoneal injection etimizol penetrates brain cells. At this time the greater portion of the drug is found in cytosol. In five minutes the maximal part of the label gets bound with cell nuclei and microsomal protein fraction extracted with 0.14 M NaCl. These two cell fractions show the highest radioactivity throughout the entire observation period (up to 7 days). Since these fractions are reported to be capable of calcium accumulation, a suggestion is made that metabolic effects of etimizol are likely to be related to calcium metabolism.
