  • Publication number: 20020182260
    Abstract: This invention provides concentrated inflammation modifiers obtained from various plant, animal, and mineral sources, and methods for the preparation of such concentrated inflammation modifiers. Also provided are methods of preventing and treating inflammation using the concentrated inflammation modifiers. The invention also provides methods of treating inflammation of the skin and mucosal membranes by administering compositions that contain concentrated inflammation modifiers as active ingredients. The methods are useful for treating inflammatory diseases, as well as for reducing or eliminating inflammation that results from transdermal delivery of a drug, or from cosmetics and skin care products. The concentrated inflammation modifiers and methods are also useful for enhancing wound healing and skin aging.

  • Patent number: 6190691
    Abstract: The present invention provides a number of screening methods for evaluating compounds capable of suppressing cytokine production either in vitro or in vivo. The methods generally involve stimulating the production of a cytokine in a cell, exposing a portion of the cells to a putative cytokine modulating agent and determining subsequent levels of cytokine production in the cells. Additionally, the present invention provides certain compounds identified by this method.

  • Patent number: 5490415
    Abstract: A diffusion test apparatus (2), used to test diffusion of a drug within a vehicle through a test membrane (8), includes a receiver assembly (6) and a donor assembly (4) secured to one another. The receiver assembly includes a number of open-top receiver receptacles (26) arranged in a chosen pattern along its face (12). Similarly, the donor assembly includes a number of open-top donor receptacles (38) arranged along its face (10) in a mirror image of the chosen pattern. The test membrane is captured between the receiver and donor faces. The drug diffuses through the test membrane and into the receiver liquid (53) during an incubation period (62). Samples (66) of the receiver liquid are preferably automatically transferred to a conventional microtiter plate (70) using a programmed liquid transfer system for assay by a scintillation counter (76).
