title: [Effect of Ca2+ on ruthenium red sorption by the brain synaptosomes of rats deprived of the paradoxical sleep phase].
abstract: A sorption of ruthenium red by the rat's brain synaptosomes under condition of a paradoxical sleep deprivation: the number of dye binding sites decreased, whereas the affinity for the dye increased. If synaptosomes were cultivated in the Ca2+-containing medium (0.5 mM), the synaptosomal dye sorption registered in rats with paradoxal sleep deprivation did not differ from that in the control rats.
