title: [Effect of substances inhibiting the ion transport on Mg2+, Ca2+-ATPase activity of synaptic plasma membranes].
abstract: The Mg2+, Ca2+-ATPase activity of plasma membranes in bull brain synaptosomas was studied as affected by ruthenium red, hexamine cobalt, aminazine, verapamyl, melipramin, lanthanum acetate and oligomycin. Lanthanum acetate in a concentration of 5.10(-5)M is shown to inhibit completely the enzyme activity. Ruthenium red and hexamine cobalt in a concentration of 10(-4) inhibit this ATPase activity by 50-60%. Melipramin, aminazine, verapamyl in concentrations of 10(-6)-10(-4)M and oligomycin in a concentration of 0.01-5 microgram/ml have no effect on the enzyme activity.
