    摘要： An improved photographic element comprises a support bearing at least one silver halide emulsion layer having associated therewith a hydrazide compound that functions as a scavenger for oxidized developing agent. The hydrazide compound includes an electron-withdrawing and aqueous-solubilizing group on an aromatic ring linked to the carbonyl of the hydrazide group and a ballasting group on an aromatic ring linked to a nitrogen atom of the hydrazide group. Preferably, the hydrazide compound is incorporated in a photographic element which comprises a four-equivalent 5-pyrazolone magenta-dye-forming coupler.

    摘要： A dry analytical element has been prepared for the assay of leucine aminopeptidase at a pH of 6.5 to 11. The element zone contains an aromatic substrate for the enzyme. This substrate provides an aromatic reactant which has a primary amino group on the aromatic ring in the ortho or para position to an electron donor group. The aromatic reactant is oxidized with an oxidizing compound (such as an oxidase) and the oxidized compound reacts with a ballasted color-forming coupler to provide a dye.
