METHOD OF CHANGING EFFICIENT VISCOSITY OF WEAK GELS BASED ON L-CYSTEINE AND SILVER NITRATE Russian patent published in 2011 - IPC A61K9/00 A61L2/16 A61P31/00 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, in particular, to obtaining gels based on L-cysteine and silver nitrate. Method of obtaining weak gels based on L-cysteine and silver nitrate includes preparation of water solution, which contains fractal clusters based on L-cysteine and silver nitrate of concentration 0.5·10^-4 mMol to 1.17·10^-2 mMol of L-cysteine in 1 ml of solution and silver nitrate, whose concentration is 1.25 times higher than concentration of L-cysteine, preparation is mixed, mixture is kept for maturing in protected against sun place for 10 hours at room temperature, to obtained solution of clusters added is water solution of alkali or alkali-earth metal in such amount that content of metal sulfate in mixture constitutes from 2.5·10^-4 mMol to 8·10^-4 mMol in 1 ml, mixture is kept in thermostat at temperature 30°C in protected against light place for 20 hours.

EFFECT: invention makes it possible to obtain weak gels base of on L-cysteine and silver nitrate with specified efficient viscosity.
