 Title    Organometallics and Quaternary Ammonium Salts Affect Calcium Ion Desorption from Lecithin Liposome Membranes  
 Abstract    The objective of the present work was to compare the effects of groups o f tin and lead organometallic com pounds and their mixtures with amphiphilic quaternary ammonium salts (Q A S) on the process of calcium ion desorption from lecithin liposom e membranes, as de­ pendent on the properties of the hydrophilic and hydrophobic parts o f QAS. In the investiga­ tions the method of radioactive labels was applied. Synergism and antagonism in the action of both groups o f compounds were found. The effectiveness o f the cooperation depended more on chain length o f Q A S compounds than on the size and polarity of their hydrophobic parts. The most effective of all compounds studied was a the mixture of benzyldimethylam-monium chloride in a mixture with tripropyltin. Since the rate of calcium desorption proved to be a good measure o f efficacy of biologically active surfactants, it seem s that the conclu­ sions reached in this paper may be useful for choosing compounds which are able to decon­ taminate the environm ent polluted with heavy metals.
