Abstract: The invention described herein relates to the composition of a liquid in which a silver ion moiety can act as a preservative as well as an astringent for the inhibition of microbial infections of the eye.

Abstract: The present invention relates to a patch, which can be used to secure catheters, wound drainage devices, and/or drug delivery devices, when said catheter and related devices are inserted into the body. The invention also can deliver antimicrobial substances to the site of insertion of a catheter and related devices into a body as well as other medicinal factors, such as wound and tissue healing factors that may be desired to be delivered to the site of insertion.

Abstract: The present invention relates to the preparation of a hemostatic dressing in the form of a powder that is particularly applicable for stemming severe bleeding and for incorporation of the powder into dressings that can stabilize the site of tissue injury, and simultaneously act as an antimicrobial agent.

Abstract: The invention described herein relates to the preparation of silver compounds prepared from pectin and pectin derivatives and the process for preparing them. The silver derivatives thus prepared are amenable for use in the preparation of medical and/or veterinary dressings or implants.

Abstract: The specification discloses an alginate foam composition dressing which may be prepared with or without a backing. The foam dressing exhibits unique capability in including soluble or insoluble medicaments as part of the alginate foam composition, attributes not inherent in alginate dressings prepared by spinning. The dressings so prepared also eliminate the need for adhesives and secondary dressings for retaining an alginate dressing on a wound site.

Abstract: The invention described herein relates to the preparation of cellulosic foam products prepared from silver alginate and derivatives thereof and the process for preparing them. The silver alginate products and related silver products are amenable for use in the preparation of medical and veterinary dressings for the treatment of burns, wounds, ulcerated lesions, and related pathological states.

Abstract: The specification discloses an alginate composition in which medicaments or cells may be interspersed with aqueous insoluble alginate molecules, so that pellets prepared by this procedure would survive the stomach contents, any enzymatic activity contained therein, as well as the low pH, and gradually dissolve in the intestinal tract behaving as a controlled release system of any specific medicament or cells including, but not limited to, vaccines that are entrapped in the alginate coacervate. Orally administered particles so prepared could be used to eliminate the need for parenteral needle inoculation of various medicaments in man and animals.

Abstract: The invention described herein relates to the preparation of cellulosic foam products prepared from silver alginate and derivatives thereof and the process for preparing them. The silver alginate products and related silver products are amenable for use in the preparation of medical and veterinary dressings for the treatment of burns, wounds, ulcerated lesions, and related pathological states.

Abstract: The invention described herein relates to the preparation of cellulosic foam products prepared from pectin and pectin derivatives and the process for preparing them. The cellulosic foam products are amenable for use in the preparation of medical and veterinary dressings for the treatment of wounds and related pathological states.

Abstract: A composition sodium alginate which is capable of being formed into an insoluble alginate salt in a mold or dish which insoluble alginate salt may be frozen and lyophilized resulting in an alginate foam product which has utility in wound management as a dressing, in surgical, and implant procedures. The insoluble alginate salt thus formed may also be prepared as a coercive mixture or covalent-link mixture with insolubilizing chemical agents which thus provide a product having utility as a medical dressing, in surgical, and implant procedures, which can retain their integrity in or on tissues over extended periods of time and a method of making the same.

Abstract: The specification discloses an alginate dressing comprising a fibrous alginate layer needle punched to a non-alginate backing web such that fibers from the alginate layer penetrate into and are interlocked with the backing web thereby affixing the alginate layer to the backing web. The dressing exhibits improved absorbency and long-term stability when used in the treatment of wounds. The dressing also eliminates the need for adhesives and secondary dressings for retaining an alginate fibrous dressing on a wound site.

Abstract: A vaccine for protecting animals against infection by Dirofilaria which comprises fractions of extracts of the adult organisms of Dirofilaria.

Abstract: Detection of antigens in a biological specimen of animal origin by means of antibody-sensitized microbial particles, which particles may be sensitized from a whole immunoglobulin fraction, an immunoglobulin fraction derived therefrom (IgG), a purified antibody fraction or the whole serum containing immunoglobulin molecules.

Abstract: Detection of gentamicin is made possible by preparing an analytical body comprising a macromolecule which carries gentamicin, attached to a particle.

Abstract: A method is described for conducting immunological tests in which a hapten or antigen is coupled to a soluble macromolecule of natural origin which complex is then aggregated into a particulate suspension which can then be used in an agglutination or indirect agglutination test procedure for detecting antigens or haptens similar in special configuration to that coupled to the macromolecule or detecting antibodies specific for such haptens or antigens. The aggregation for the protein can be affected initially with subsequent coupling of the hapten or antigen to it, or aggregation can be effected after hapten or antigen coupling to the macromolecule.The test procedure utilizing such aggregate macromolecule-hapten or macromolecule-antigen complexes may be achieved in indirect agglutination test in well trays or by the augmentation with antibody against the species of animal from which antibody against the hapten or antigen has been prepared, effect a direct agglutination on a slide.
