  • Patent number: 5422076
    Abstract: An apparatus for sanitarily and easily collecting urine or other liquid specimens for testing, including a collection vessel having a handle portion and a cover. The relatively long, narrow dimensions of the collection vessel assure maneuverability. The handle also assists maneuverability, as well as facilitating sanitary collection of the specimen. The easy-to-use cover further ensures that the specimen remains free from contamination after collection, yet the user of the apparatus can readily and sanitarily seal the vessel.

  • Patent number: 5411876
    Abstract: Improvements to the polymerase chain reaction (PCR), a process for in vitro enzymatic amplification of specific nucleic acid sequences, can be achieved by changing the way that PCR reagents are mixed and the enzymatic reaction is started and by the replacement of mineral oil, commonly used as a vapor barrier to minimize solvent evaporation, by a grease or wax. The use of such mixtures allows for the delay of reagent mixing until the first heating step of a PCR amplification, thereby reducing the enzymatic generation of nonspecific products which occurs when a complete mixture of PCR reagents, with or without test sample, stands at room temperature or below. These mixtures increase the shelf-life of PCR reagents and increase protection of the laboratory environment against contamination by PCR product.

  • Patent number: 5209920
    Abstract: Inbred Lewis (LEW/N) female rats develop an arthritis in response to Group A streptococcal cell wall peptidoglycanpolysaccharide (SCW) which mimics human rheumatoid arthritis. Histocompatible Fischer (F344/N) rats, on the other hand, do not develop arthritis in response to the same SCW stimulus. To evaluate this difference in inflammatory reactivity between the two strains, the function of the hypothalamic-pituitary-adrenal axis and its ability to modulate the development of the inflammatory response was studied. It has been found that, in contrast to F344/N rats, LEW/N rats had markedly impaired plasma ACTH and corticosterone responses to SCW, recombinant human Interleukin-1 alpha (IL-1 alpha), the serotonin agonist, quipazine, and synthetic rat corticotropin-releasing hormone (CRH). In addition, LEW/N rats compared to F344/N rats had smaller adrenal glands and larger thymuses. Treatment of LEW/N rats with replacement doses of dexamethasone decreased the severity of their SCW-induced arthritis.

  • Patent number: 5018531
    Abstract: A system to record the color, size and location of skin blemishes on the skin using an objective standard is provided. The system includes a color scale containing colors and shades of colors sufficient to portray a skin blemish; a blemish-size gauge for measuring the size of the blemish; a distance scale for measuring the distance of the blemish from reference points; and a body map of the skin surface of the entire human body with reference points for recording the location of the blemish. Each color in the color scale and size in the size gauge is given an individual designation for easy reference. The color scale and the measuring devices may be combined in one multi-functional tool and with a folded chart for easy storage in a folder to protect the colors from changes due to exposure to light.

  • Patent number: 4995402
    Abstract: An assay employing a tracer comprising a ligand having a mercury label wherein mercury label is released from at least one of a bound or free tracer phase and iunteracts with a metal. Analyte is determined by a change in at least one property of the metal caused by such interaction. The invention also relates to a device for such an assay wherein mercury ions released from a free or bound tracer are caused to eventually amalgamate with a metal, and the presence and/or amount of analyte is determined by changes in the metal resulting from the eventual amalgamation which may be measured electrically or by other means. The invention also relates to novel assay instruments, novel lancets, assay sensors, assay sensor packets, instrumentation and combinations of assay components, and related methods.

  • Patent number: 4979515
    Abstract: A blood sampling kit having a plurality of glass vials for receiving blood therein; a puncture pin for puncturing the skin of the subject to be tested; an alcohol swab for cleansing the area punctured, and an envelope for returning the specimen to a laboratory. The specimen receiving kit further comprises a quantity of clay like material for sealing the ends of the blood vials after the blood sample has been received therein, so that blood is not lost during transit. The system provides that the test subject would receive the kit containing the above- referenced items to prick one's finger, place blood into the plurality of blood-receiving vials, close off the end of the vials with a quantity of clay plug; return the vials to the kit, reseal the blood it, place the kit in a sealable plastic bag container, note one's name and address on the plastic bag and place the kit in an envelope provided for returning to the laboratory for testing.

  • Patent number: 4970053
    Abstract: A reagent cartridge for use in an automated clinical analyzer, the reagent cartridge including a plurality of storage compartments each including wall members. The reagent cartridge includes connecting members formed integrally with the storage compartments for holding the storage compartments in a fixed relationship with respect to each other and separating the wall members from each other to thus prevent reagent migration between adjacent reagent compartments. Each of the storage compartments includes an access opening and a neck formed about the opening, the neck including a collar that is spaced a predetermined distance from a bottom wall of the associated storage compartment, the predetermined distance adapted to accommodate an automatically controlled reagent transfer probe.
