  • Patent number: 5874006
    Abstract: A process for the aseptic concentration of collagen from about 0.25% (w/w) suspensions to gels of 15% using vortex flow filtration with a variety of membrane types--ultrafiltration and microfiltration and polymeric and stainless steel is provided. The resulting gels are suitable for use in medical products and/or pharmaceutical formulations. This process achieves high degree of concentration in a closed system and at high flux with minimal trans-membrane pressure drop.

  • Patent number: 5874402
    Abstract: Methods are provided for the treatment of a host suffering from a cellular proliferative disease through administration of a chemotherapeutic agent in conjunction with a cell membrane permeant. Optionally, the cell membrane permeant and/or chemotherapeutic agent will be present in a pharmaceutically acceptable vehicle capable of acting as a depot. In the subject methods, the chemotherapeutic agent and membrane permeant are administered at least proximal to a target site of the host. Administration of chemotherapeutic agents in accordance with the subject methods results in improved efficacy of, and/or decreased host toxicity to, the intralesionally administered chemotherapeutic agent.

  • Patent number: 5573781
    Abstract: Methods and compositions are provided for the treatment of a host with a cellular proliferative disease, particularly a neoplasia. In the subject methods, a pharmaceutically acceptable, substantially anhydrous, injectable semi-solid composition which acts as a depot for a cytostatic agent, is administered to a lesion of the disease, particularly intralesionally. The subject compositions comprise a water immiscible, fatty acid ester matrix and a cytostatic agent.

  • Patent number: 5290552
    Abstract: The present invention provides a surgical adhesive comprising, in an aqueous composition, fibrinogen, FXIII, collagen, thrombin, Ca.sup.2+ and optionally, an antifibrinolytic agent. The present adhesive may be formed from the patient's plasma without the use of any added reagents for concentration or isolation of the fibrinogen. Conveniently, the adhesive is formulated as a two-part composition which is mixed together just prior to use.
