Rapid determination of the identity of aqueous drug solutions

The stationary stability of giant heterophase clusters (GHCs) of water in samples of sodium chloride isotonic aqueous solutions from three manufacturers has been studied. The influence of the NaCl concentration on the relaxation kinetics of GHCs is established. A method for determining the identity of aqueous drug solutions without violating the integrity of the packaging is developed. © 2009 Springer Science+Business Media, Inc

Physicochemical properties and biological activity of the water depleted of heavy isotopes

Data on physicochemical properties of the light water (deuterium concentration is reduced to the ratio D/H = 4 ppm and that of the isotope of oxygen 18-to the ratio 18O/16O = 750 ppm) have been obtained. They include the melting and boiling points, kinematic viscosity, density, the spin-spin proton relaxation time, self-diffusion coefficients, and the small-angle laser light scattering. It was found out that the biological activity of the light water was determined by the mechanisms different from the ligand-induced toxic effects. An explanation was proposed for the detected significant changes of the light water as compared with the high-resistivity water having geochemically ordinary isotope composition. This explanation was based on the mechanism of formation of supramolecular density inhomogeneities in water representing the deuterium-stabilized heterophase clusters. © 2011 Allerton Press, Inc
