Abstract: The invention relates to a self-supporting, biodegradable film comprising a C10-C22-acylated derivative of hyaluronic acid according to the general formula (I), where R is H+ or Na+, and where R1 is H or —C(?O)CxHy, where x is an integer within the range from 9 to 21 and y is an integer within the range from 11 to 43 and CxHy is a linear or branched, saturated or unsaturated C9-C21 chain, wherein in at least one repeating unit one or more of R1 is —C(?O)CxHy and where n is within the range from 12 to 4000; a method of preparation thereof and use thereof.

Abstract: Disclosed is a method of preparing a medical preparation with a carrier based on hyaluronan and/or its derivatives, which can be used in the field of medicine and cosmetics. The medical preparation comprises a conjugate of hyaluronic acid and/or its derivative with a medical substance, according to the general formula A-S—N, where: A is the medical substance; S is the way of linking the medical substance with the carrier; and N is the carrier based on hyaluronic acid and/or its derivatives.

Abstract: The invention relates to the preparation and the use of ?,?-unsaturated aldehydes in the structure of sulfated polysaccharides. It concerns the derivatives with a conjugated double bond in the 4th and 5th positions of the galactopyranose part situated in the 6th position with respect to the aldehyde, according to the general structural formula (I) or its hydrated form according to the general structural formula (II). The preparation of these derivatives derives from sulfated polysaccharides containing a galactopyranose ring sulfated in the 4th position that is bound in the polymer chain via ?(1?3) or ?(1?3) O-glycosidic bond. In the described solution, the sulfated polysaccharides undergo a regio- and chemoselective oxidation to form C6-saturated aldehyde, which, via a direct elimination of the sulfate group, provides the ?,?-unsaturated derivative according to the general formula (I) or (II).

Abstract: The invention relates to the biodegradable fibres which are based on hydrophobic derivatives of hylauronan, specifically on the base of the hyaluronan derivative C11-C18-acylated on hydroxyl groups of hyaluronic acid, and use thereof. Further the invention relates to the preparation of these fibres which is performed with the use of the wet spinning method in a coagulation bath comprising water solution of organic acid, with the production of continuous monofiles which can be thereafter processed to threads and further to textiles, knitted textiles, or nonwoven textiles. These textiles, knitted textiles or nonwoven textiles can be used for example for the production of implantable surgical material for human and veterinary medicine.

Abstract: The invention relates to the method of the preparation of polysaccharide fibers based on hyaluronic acid, a compound comprising hyaluronic acid and metal ions, schizophylan, chitin/chitosan-glucan complex, a compound comprising chitin/chitosan-glucan complex and metal ions, internal mixture of chitin and chitosan, a compound comprising internal mixture of chitin and metal ions, sodium alginate, potassium alginate, ammonium alginate, xanthane, xanthane sodium salt, xanthane potassium salt, oxycellulose, oxycellulose sodium salt, oxycellulose potassium salt, carboxymethyl cellulose, carboxymethyl cellulose sodium salt, and carboxymethyl cellulose potassium salt, or a mixture of polysaccharides, in a non-stationary coagulation bath.

Abstract: The invention relates to a preparation containing a pharmacologically suitable chitosan-glucan complex or a salt thereof, either alone or in combination with one or more polysaccharides or suitable salts thereof and an antiseptic agent, that is intended for wound healing and that, besides accelerating wound healing, is at the same time able to prevent a bandage adhesion to the wound. The preparation according to the invention, having been applied, indirectly supports the healing processes in the wound and drains the redundant secretion together with the tissue mediators and enzymes that support the healing. By doing this, it provides for the necessary hydration of the wound and its surroundings, without any maceration of the surrounding skin or drying and sticking to the wound. An addition of antiseptic agents prevents a further infection. The preparation contains 0.01 to 100% by weight of chitosan-glucan complex, 0 to 99.99% by weight of another polysaccharide and 0 to 50% by weight of an antiseptic agent.
