Abstract: The invention relates to a method for processing an aqueous gel of nanofibrillar cellulose by removing water from the aqueous gel by means of an organic solvent miscible with water. In the method: aqueous gel is introduced into a volume of organic solvent miscible with water in a controlled manner so that the aqueous gel is kept as a separate phase and forms discrete physical entities containing the nanofibrillar cellulose within the phase; water is changed with the organic solvent in said discrete physical entities of nanofibrillar cellulose; and the physical entities are separated from the volume of organic solvent.

Abstract: The present invention discloses a mercapto-modified biocompatible macromolecule derivative with a low degree of modification. The mercapto-modified biocompatible macromolecule derivative not only maintains the initial structure, physiological function and biocompatibility as much as possible, but also allows the preparation of the biocompatible macromolecule cross-linked material with a low degree of cross-linking through the effectively chemical cross-linking with the introduced mercapto group. The present invention further discloses a disulfide-bond cross-linked biocompatible macromolecule material with a very low degree of cross-linking.
Abstract: The invention relates to medicine, hepatology and pharmacology and can be used for producing and using a pharmaceutical composition based on a hepatoprotector and a prebiotic for treating and preventing liver diseases which are caused by lipid-cholesterol exchange and selected from the following group: cholelitiasis mainly with cholesterol stones, alcoholic and non-alcoholic steatohepatitis, biliary cirrhosis, cholesterol imbibition gallbladder and drug-induced and toxic liver damage. The pharmaceutical composition is administered by mouth and contains a hepatoprotector and a prebiotic taken, as an active agent, in therapeutically effective doses. The invention contributes to the liver's functional recovery in a short time and prevents disease recidivation owing to the recovery of cholesterol exchange and intestinal biocenosis as a result of the synergistic interaction of a hepatoprotector and a prebiotic, thereby also preventing hepatoprotector side effects.
