Abstract: A solid storage stable composition comprising ibuprofen or a pharmaceutically acceptable salt thereof and codeine or a pharmaceutically acceptable salt thereof together with a sufficient amount of a pharmaceutically acceptable insoluble salt of carboxymethylcellulose to prevent discoloration of the composition.

Abstract: An improved card for use in an automated machine to detect the continued existence of microbes in a plurality of wells containing different media so that the organism can be speciated. The card includes an improved configuration wherein the wells have different reduced oxygen environments and all of the wells have an improved bubble chamber connected to the well by a bifurcated passage.

Abstract: Microorganisms in a specimen are detected, identified, and enumerated by introducing the specimen into a sampling cartridge and diluting the specimen with a known volume of water within the cartridge. The cartridge has a manifold and several cassettes attached to the manifold. Each cassette contains a serpentine flow channel having a series of filters therein and a detection cell located downstream from each filter. The flow channel in each cassette also contains a culture medium which is freeze dried and is highly selective in the sense that it promotes the growth of one type of microorganism, but not others. The mixture of the specimen and water flows from the manifold into the flow channel of each cassette where it rehydrates the culture medium therein and further flows through the filters. Each filter removes a known proportion of the microorganisms from the mixture of specimen, water and medium, thereby effecting a serial dilution.

Abstract: A broth medium for the detection of Candida yeasts, Saccharamyces cerevisiae, Torulopsis glabrata, and Aspergillus niger in urine. The medium employs chloramphenicol and potassium tellurite to inhibit the growth of gram-positive and gram-negative organisms. The medium also uses reduced aniline blue biological pH indicator.

Abstract: A medium for the detection and identification of Escherichia coli (E. coli) in urine samples.The medium employs para-coumaric acid, saponin and 3,4-dihydroxybenzoic acid to inhibit growth of unwanted microorganisms and thus eliminate false positive test results.

Abstract: Process of preparing reduced aniline blue pH indicator for use in detecting presence of microorganisms in culture media. The process involves reducing aniline blue by the sequential addition of sodium thioglycollate. The reduced aniline blue indicator may be used in certain media designed for use in the cards and wells of the mechanism described in applications AUTOMATED MICROBIAL ANALYZER and MACHINE AND PROCESS FOR READING CARDS CONTAINING SPECIMENS.

Abstract: A broth medium for the detection of Staphylococcus aureus in urine. The medium employs mannitol to promote growth of S. aureus, potassium tellurite to inhibit growth of gram-negative organisms, amphotericin B to inhibit growth of yeast, and DNA methyl green indicator.
