[The effect of polarization of the vascular wall on the ion transport and contractile activity of the rat tail artery].
The effects of the blood velocity upon the responsiveness of blood vessels seem to be based on the processes inducing a deforming of the diffuse part of a double electrical layer at the border between the blood and vascular wall of the rat tail artery. Salts of polyvalent metals were found to diminish the negativity of the transmural potential and to diminish the contractile activity and the tone of the blood vessels. Heparin exerted an opposite effect.
