    Abstract: This invention is in the field of animal food, in particular food for female animals in their reproductive phase. Food according to the invention improves the fertility of animals and increases their chances on a pregnancy. It was found that the fertility of animals may be improved by feeding the animal with a certain amount of naturally occurring immune enhancing ingredients such as beta-glucans and/or phytohormones like auxin or gibberellic acid. Also, combinations of these substances, in particular the combination of beta-glucans and phytohormones, were shown to have a synergistic effect in that they improved the fertility of the animal more than these individual components on their own.

  • Publication number: 20040248847
    Abstract: An ophthalmic pharmaceutical composition containing acetylcysteine as the active ingredient having a mucolitic action, suitable for administration in eyedrops, where N-acetyl-cysteine is neutralised with base DEAE-dextrane in order to reach pH levels preferably between 6.0 and 7.5, and having a physiologically acceptable osmolarity less than 320 mOsm/kg. The presence of a neutralising agent for N-acetyl-cysteine that does not negatively affect the composition osmolarity allows the formulation to be isotonic or even hypotonic, thus avoiding the irritative and potentially damaging effects of previous ophthalmic products containing N-acetyl-cysteine.

  • Publication number: 20040235791
    Abstract: A method of reducing scar formation at a wound site includes contacting the wound site with an effective scar reducing amount of a cross-linked polysaccharide having a positive charge and thereby reducing scar formation as the wound site heals. Such polysaccharide include bioabsorbable cross-linked dextrans or alginates. The positive charge may be provided by diethylaminoethyl (DEAE) moieties. The cross-linked polysaccharide can be applied to the wound site as a powder or bead. The cross-linked polysaccharide may also be contained in a composition including a pharmaceutically acceptable vehicle. Biocompatable surgical devices are provided with an effective scar reducing amount of a cross-linked polysaccharide having a positive charge which reduce scar formation at healing wound sites. A method of reducing TGF-&bgr; activity is also provided.
