[Role of vanadium in regulation of oxidation-reduction reactions in membranes].

The effect of vanadium on the microsomal membrane system of rat brain and heart was studied. The results obtained exclude the involvement of vanadium in redox processes occurring in brain microsomes. In heart microsomes vanadium, being a redox agent, can control important processes of heart metabolism, while NADH-vanadate-reductase may be a very effective regulator of local pH in heart intracellular membrane systems.
