  • Cornea preservation medium
    Patent number: 7087369
    Abstract: Steinhardt defined medium preserves cornea tissue during cold storage. Tissue preservation kits comprise a premeasured amount of Steinhardt's medium and copackaged instructions describing use of the medium to preserve a tissue. Kits for making Steinhardt medium comprise premeasured amounts of medium ingredients; and copackaged instructions describing how to combine the ingredients to make the medium. The medium is made by combining the recited ingredients, and used by incubating a tissue in the medium.

  • Methods for screening compounds to determine calcium leak channel inhibition activity
    Patent number: 5559004
    Abstract: Intracellular free calcium concentrations are lowered by administering certain dihydropyridine derivatives to cells. Dihydropyridine and other test compounds are screened for their ability to lower intracellular free calcium, particularly by inhibiting the influx of calcium through calcium leak channels, and the identified compounds incorporated into pharmaceutical compositions. Exemplary dihydropyridine derivative compounds include 4-(3-trifluoromethylphenyl)-2,6-dimethyl-3,5-dicarbomethoxy-1,4-dihydropyr idine; 4-(4-bromophenyl)-2,6-dimethyl-3,5-dicarbomethoxy-1,4-dihydropyridine; 4-(4-trifluoromethylphenyl)-2,6-dimethyl-3,5-dicarbomethoxy-1,4-dihydropyr idine; 4-(4-methylphenyl)-2,6-dimethyl-3,5-dicarbomethoxy-1,4-dihydropyridine; and 4-(4-cyanophenyl)-2,6-dimethyl-3,5-dicarbomethoxy-1,4-dihydropyridine.
