Patent EP-0232986-B1 (EP)
IPC: G01M11/02
Filed: 1987-01-16
Granted: 1989-09-27
Abstract: A method for evaluating the in vivo ability of a contact lens to become or remain wet includes the steps of supporting the subject's head to determine a fixed orientation of the lens, illuminating the lens with coherent light, imaging the pre-lens tear film in a manner to form an interference pattern, recording in a time sequence manner the image formed thereby, and determining the tear film thickness by correlating the interference bands of the recorded image. The classical contact angle is derived, and other measures, such as the time interval from blink until the onset of tear film breakup, or the time until the film evaporates, and the initial or average film thickness are derived. In addition, the nature and evolution of localized dry spots may be directly observed, clarifying the causes of tear film breakdown on worn contact lenses. The invention enables wetting characteristics to be evaluated as they are affected by lens material, lens aging and lens soiling, as well as the evaluation of solvents, additives and cleaners, for their effects on wetting characteristics.Apparatus for performing the method includes means for supporting the head so as to determine a fixed location of the contact lens (8), a coherent light source (9), and a camera (19) focused at the pre-lens film from a position to image light from the source specularly reflected from the front and rear surfaces of the tear film. A film motion analyzer (50) provides numerical coordinates of interference bands, and a microprocessor (60) analyses the coordinates to provide a quantitative measure of lens position or wetting characteristics.

Title: The sm-b/b1 antigens, the cloning of the sm-b/b1 antigens and the detection of systemic lupus erythematosus by using the sm-b/b1 antigens
IPC: C12N15/00
Filed: 1988-09-13
Granted: 1993-03-10
Abstract: SnRNP proteins are isolated, as by immunoaffinity chromatography, using antibodies from a serum sample of a living being affected by systemic lupus erythematosus. The Sm-B and/or Sm-B min  polypeptides are in turn isolated from the snRNP protein complex as by gel electrophoresis and electroelution. The amino terminus of the Sm-B and/or Sm-B min  polypeptides are then sequenced, and labelled DNA probes with nucleotide sequences complementary to that encoding the amino acid sequence are synthesized. A human cDNA library in a lambda cloning vector is transferred to appropriate filters such as nitrocellulose filters. These filters are screened as by hybidization with the labelled probes to identify the cDNA clones in the library with sequences matching those of the labelled probes. The cDNA encoding the Sm-B and/or Sm-B min  proteins are then subcloned. The Sm-B and/or Sm-B min  polypeptides are then isolated as by immunoaffinity chromatography and, if further desired, as by HPLC chromatography. An assay is then made with the isolated Sm-B and/or Sm-B min  polypeptides by reacting the Sm-B and/or Sm-B min polypeptides with a serum sample of a living being to determine whether the living being is affected by systemic lupus erythematosus. The assay may also be made with a mixture of the isolated Sm-B and/or Sm-B min  polypeptides and an isolated Sm-D polypeptide (isolated substantially as described above). The assay may be performed as by an enzyme-linked immunoabsorbant such as anti-human IgG/IgM antibodies covalently attached to an enzyme indicator. Lactoperoxidase/alkaline phosphatase are each an example of an enzyme indicator to indicate, as by a distinctive color, an affected person.

Granted: 1993-05-12
Abstract: A jellied food is manufactured by the manner that a jelly-like substance mixed and heat agitated in the liquid state is first filled in the container and a cream- or jam-like substance separately prepared and solidified in a predetermined shape is then incorporated into the jelly-like substance in the container at a temperature range at which the jelly-like substance is not solidified, and in the range below a melting point of the gelling agent contained in the jelly-like substance. The cream- or jam-like substance includes a gelling agent having a melting point lower than that of the gelling agent of the jelly-like substance. The container is then heat sterilized at a temperature of the melting point of the gelling agent of the jelly-like substance with the cream- or jam-like substance preserving the shape and quality at the time when it was contained in the container. The cream- or jam-like substance is also prepared by diluting the same with an amylopectin and water in a paste substance. The thus prepared substance is frozen, and the frozen paste substance is incorporated into the jelly-like substance separately prepared and contained in the container before the jelly-like substance is not solidified. The parts of the jelly-like substance surrounding the frozen substance are instantaneously solidified to form a thin film therearound. The container is then sealed and heat sterilized, whereby a jellied food with the cream- or jam-like substance preserving the shape and quality at the time when it was contained in the container, can be obtained.
