  • Publication number: 20020127223
    Abstract: Method for reducing side-effects of a drug caused by undesired effects of said drug upon body cells which are not the intended target of said drug comprising the preferential delivery of antidote for said drug to said body cells when said drug is used, said preferential delivery effected by attaching to said antidote antibody with affinity for said body cells.

  • Patent number: 6440118
    Abstract: In a hypodermic needle having an end that attaches to a syringe, an elongated hollow shaft for passing fluid terminated at a sharpened point; the improvement comprising an electrically insulating layer positioned on the shaft and at least one electrically conductive area positioned on the insulating layer. The electrically conductive area being adapted to be connected to an electrical source. A method of determining when a hypodermic needle penetrates into tissue, vein, or lumen by providing an electrical source; connecting the electrical source electrically to a hypodermic needle designed to provide two electrically conducting portions, spaced apart from each other, and near a point on the hypodermic needle.

  • Patent number: 5328614
    Abstract: Apparatus and method wherein body fluid to be treated flows proximate the surface of hepatocytes, the hepatocyte treatment of said body fluid substantially being made to occur across a layer of albumin concentration substantially greater than the concentration in said body fluid, the albumin layer being less than 3 microns.

  • Patent number: 5175004
    Abstract: A method for creating a propagatable, new combinant cell with differentiated function to replenish dwindling number of similar cells in diseased subjects. The new combinant cell is obtained by 1) removing a nucleated cell, which is of the same differentiative phenotype as the diseased cells, from a subject and isolating therefrom a karyoplast, 2) isolating from a source other than said subject a proliferation-prone cell which is of the same differentiative phenotype or which is predestined to become the same phenotype as the diseased cells and isolating therefrom a cytoplast, 3) fusing the cytoplast and karyoplast to form a propagatable, new combinant cell, 4) propagating the combinant cell in culture, and 5) transplanting the combinant cells into said subject. In another embodiment the karyoplast donor is histocompatible to said subject. In yet another embodiment a whole cell is used in lieu of a karyoplast for fusion with the cytoplast.

  • Patent number: 5078885
    Abstract: The method for removing molecules bound to proteins in body fluid comprising positioning said body fluid in contact with one side of an albumin-dimensioned bottle-neck pore membrane and positioning proximate the opposite side of said membrane aqueously suspended adsorbent. The apparatus comprises an albumin-dimensioned bottle-neck pore membrane and means associated therewith for positioning body fluid to be treated in contact with one side of said membrane and aqueously suspended adsorbent located proximate the opposite side of said membrane.
