Sustained release medicine preparation and its production
This sustained release medicine preparation is obtained by homogenizing an organic or inorganic medicine active substance, a fatty acid required for attaining a continuous phase transition or its salt and an ethylene vinyl acetate copolymer to give a uniform mixture.
[Analytic and biological standardization of Prunus avium extracts].
The result of experiments demonstrated that the standard Novicardine improves the contraction force of heart muscle by some 20-25%, and at the same time doesn't exert influence on the basic electrophysiological parameters and doesn't cause significant changes in heart rate.
Selective complexometric determination of glyphosate and related compounds
- J. Répási
A complexometric method has been developed for the selective determination of glyphosate and related compounds. The method is based upon the different pH-dependence of tridentate and tetradentate…
