Patent RU-2006102028-A (RU)
IPC: A61P35/00
Filed: 2004-06-28
Abstract: This invention relates to stable pharmaceutical compositions of 5,10-methylene-(6R)-, -(6S)-, or -(6R,S)-tetrahydrofolate (MTHF), by adjusting a basic pH and the simultaneous use of citrate. Stabilisation is effected even in the absence of a reducing agent. The present invention is particularly suitable for producing lyophlisation solutions and lyophilisates or dry powders and dry mixtures, since the stable MTHF solutions can be used in high concentrations for filling corresponding vessels such as vials, ampoules, etc. The lyophilisates have a surprisingly long shelf life and are surprisingly stable. They can be reconstituted without problems by adding wateror aqueous solutions, and the final clear injection solutions again exhibit excellent stability properties. Moreover, the present invention even makes it possible to prepare difficulty soluble calcium 15 or acidic salts of MTHF in high concentrations and as physiologically compatible isotonic solutions.

IPC: D21H21/00
Filed: 2004-10-27
Abstract: The invention relates to cardboard used in authenticity products, comprising a fiber matrix having two surfaces, whereby the second surface of the fiber layer has a layer of surface sizing containing a marking agent in a particle form, its particle size being smaller than 50 μm. By incorporating the marking agent into the surface sizing, the particles of the marking agent can be attached to the board, at the same time decreasing their total consumption by 80 to 90% compared with a case where they would be added to pulp. By using particles of a size less than 50 μm, a top free from streaks and roughness can be formed, which streaks might otherwise weaken the quality of the product.
Patent RU-2006113165-A (RU)
IPC: D21H17/21
Filed: 2004-11-12
Abstract: Disclosed is a method of manufacturing pulp and paper using Rhodophyta, including immersing Rhodophyta in an extraction solvent able to dissolve agar gel for a predetermined time period to dissolve the agar gel in the extraction solvent, reacting the dissolved agar gel with a reaction solvent to be converted into a fiber, curing the fiber using a curing agent, and pulping the cured fiber. The method of the current invention is advantageous because of lower manufacturing costs, due to eliminating the need to purchase wood. Further, the use of chemicals for lignin removal and bleaching drastically decreases, thus preventing environmental contamination. Furthermore, since a final product does not contain harmful chemicals, humans and the environment are not negatively affected.
