[The surface activity of vasopressin and its interaction with artificial and biological membranes].
It was determined that vasopressin has surface active properties and in nanomolic concentrations is capable to incorporate in lipoprotein monolayers which are formed from myocytes plasma membranes. By means of pH-metric and fluorescent analysis it was shown that vasopressin interacts with other membrane structures which have no specific receptors--phosphatidylcholinic liposomes and vesicles of sarcoplasmic reticulum of skeletal muscles causing increasing permeability of phospholipid bilayer for Ca2+ ions.
