title: [Effect of aminazine on the concentration of bound calcium in grape snail neurons].
abstract: By cytospectrophotometry it was shown that with the increase of chlorpromazine concentration in the external medium [CPZ]0 equal to 1-10(-8) M the concentration of bound calcium in the nuclei of neurons of Helix pomatia decreased, and at 3.2-10(-7) M chlorpromazine the Ca-concentration reduced to its minimum. A further increase in [CPZ]0 gradually increased the concentration of bound calcium, and at 1-10(-5) M chlorpromazine the concentration reached its maximum. An increase in [CPZ]0 from 1-10(-5) M to 1-10(-3) M caused a secondary decrease in the concentration of intranuclear calcium. A similar dependence was noticed for calcium bound by the cytoplasm of these cells.
