  • Publication number: 20100303921
    Abstract: The present invention relates to pharmaceutical compositions comprising a ? (1-3) ? (1-4) glucan and a pharmaceutically active agent or a botanical extract. A method to extract and purify cereal ?-glucan is also described. The high purity of the cereal ?-glucan obtained according to the present invention allows for the preparation of clear, colourless viscous liquid preparations. These liquid preparations are stable to gelling effects when kept at ambient temperatures and low ash concentrations, and can be used to prepare the pharmaceutical compositions of the present invention.

  • Publication number: 20100158988
    Abstract: Cereal ?(1-3) ?(1-4) glucan is used as a film or coating agent to produce clear, edible, biodegradable, delivery, lubricating, and protecting agents. Cereal ?(1-3) ?(1-4) glucans are distinctive polymers of glucose differentiated from other polymers by not only their source but also their physicochemical properties. The ?(1-3) ?(1-4) forms a matrix to sequester other materials, such as pharmaceutical, medical and therapeutic agents, flavours, fragrances. The technology has applications to essential oils and non-aqueous materials that are rendered deliverable by the ?(1-3) ?(1-4) glucan. The ?(1-3) ?(1-4) glucan films described may be consumed whereby they dissolve in the mouth in a controlled manner and may be used for the delivery of pharmaceutical, medical or confectionery products.

  • Publication number: 20100042070
    Abstract: Apparatus for delivering therapeutic agents to the central nervous system of a subject is described. The apparatus comprises at least one intracranial catheter and a percutaneous access device. The percutaneous access device comprises a body having at least one extracorporeal surface and at least one subcutaneous surface, the body defining at least one port for connection to an implanted intracranial catheter. The port is accessible from the extracorporeal surface of the device, but is provided with a seal such as a rubber bung between the lumen of the port and the extracorporeal surface. The percutaneous access device may have more than two ports and/or a flange. A method of implanting the percutaneous access device is also described.

  • Publication number: 20060251590
    Abstract: The present invention relates to oral compositions comprising a ?(1-3) ?(1-4) glucan and one, or more than one compound of interest. In particular, the present invention provides an oral composition comprising an effective amount of a ?(1-3) ?(1-4) glucan and an effective amount of one, or more than one of an antibacterial agent, a botanical extract, and a flavouring agent, and also provides a method of using this composition for maintaining fresh breath in a subject over a prolonged period of time.

  • Publication number: 20060122149
    Abstract: A novel method to extract and purify cereal ?-glucan is described. Cereal ? glucans are distinctive polymers of glucose differentiated from other polymers not only by their source but also by their physicochemical properties. The high purity of the cereal ?-glucan obtained according to the present invention allows for the preparation of clear, colourless viscous liquid preparations. These liquid preparations are stable to gelling effects when kept at ambient temperatures and low ash concentrations. Compositions comprising ? (1-3) ? (1-4) glucan and a freezing point depressant are also, described.

  • Patent number: 6989098
    Abstract: A process is described for the preparation f electrostatically-linked, aliphatic- or alicyclic-substituted anionic or cationic polysaccharide gels from readily available macroporous ionic polysaccharide chromatographic media, such as diethylaminoethyl (DEAE), quaternary aminoethyl (QAE) and sulfopropyl (SP) substituted polysaccharide gels. These novel gels are used for the isolation, recovery and purification of non-polar extractives using one or more extracting solvents from the group of lower alcohols, ketones, and water. The non-polar extractives may be alk(n)lyresorcinols, steroid, triterpenoid, cardiac glycosides and saponins, steryl ferulates and other phenolic acid conjugates, flavonoids, lipids, alcohol-soluble antimicrobials, prolamines or other alcohol-soluble proteolipid complexes.

  • Patent number: 6910623
    Abstract: A substantially paperboard container for releasably dispensing contents contained therein is convertible from a substantially sealed orientation to a substantially open, dispensing orientation and back to the substantially sealed orientation. The paperboard container comprises a tubular container member, a bottom member and a top member, with the top member being telescopically received within the container member to seal the top member to the container. The top member is pivotable about the hinge portion and is pivotable to the sealed orientation to substantially reseal the container member. The lid is fabricated in whole or in part, from plastic material.

  • Publication number: 20050042243
    Abstract: A simple and efficient method for the production of stable, clear, high-potency oat extracts is disclosed. The method employs the use of differential dissociation constants and ultrafiltration to stabilise extracts, prevent hazing, and prevent the loss of functional activity as an anti-irritant and anti-oxidant. Also disclosed are compositions of oat extracts derived from whole oat grains and oatmeal. Further disclosed are compositions of oat extracts for use in cosmetic, nutraceutical, therapeutic medical and veterinary preparations.
