  • Publication number: 20070224226
    Abstract: A pharmaceutical composition comprises (a) metronidazole in an antibacterially effective amount; and (b) an antifungal agent in an antifungally effective amount, illustratively comprising butoconazole or a pharmaceutically acceptable salt or ester thereof. The composition is adapted for application in a unit dose amount to a vulvovaginal surface and has at least one nonlipoidal internal phase and at least one lipoidal external phase that is bioadhesive to the vulvovaginal surface. The composition is useful for administration to a vulvovaginal surface to treat a mixed bacterial vaginosis and vulvovaginal candidiasis infection.

  • Publication number: 20050171177
    Abstract: The present invention relates to methods of treatment vulvovaginitis caused by nonspecified Candida isolates using controlled release antimycotic delivery systems. The invention utilizes a minimal number of administrations to obtain cessation of the condition. The methods and systems are especially effective against any Candida species causing vaginal irritation, and thus reduce the need for identification of the isolate prior to treatment.

  • Patent number: 5105858
    Abstract: A stackable, lightweight water dispenser bottle and method of using a plurality of such bottles in conjunction with a conventional water cooler is disclosed. The bottle comprises a generally parallelepipedal container body with rounded edges and corners with a plurality of dimples in a top portion and complementarily shaped protuberances on a bottom portion. The top portion has a central depression therein with a round hole surrounded by a cylindrical collar sealed by a screw-on cap. A neck portion rising from a central depression in the bottom portion terminates in an opening communicating with the interior of the container body and is sealed with a plastic cap after the water bottle is filled. A first such water bottle can be inverted and sealingly inserted into the opening at the top of a water cooler to partially fill the cooler.

  • Patent number: 4323642
    Abstract: Lignosulfonates are incorporated in photographic developing compositions containing an indazole antifoggant in order to prevent or retard the precipitation of the indazole. Both black-and-white developing compositions, containing such developing agents as dihydroxybenzenes and/or pyrazolidones, and color developing compositions, containing primary aromatic amino color developing agents, are effectively stabilized against precipitation of indazole antifoggants by the lignosulfonates.

  • Patent number: 4201590
    Abstract: A heat bleachable material comprises (i) at least one hexaarylbiimidazole with (ii) at least one dye, especially an antihalation or filter dye, that is reactive with the product of the hexaarylbiimidazole formed upon heating the material to a temperature above about 90.degree. C. This provides a material that becomes at least 40% colorless within about 20 minutes, typically within about 30 seconds, upon heating to a temperature as described. The dye-containing material is especially useful for antihalation and filter purposes in a photographic element. The material can be a heat bleachable dye layer of a photothermographic element. The heat bleachable dye layer can also be useful in a thermographic element.

The motor includes a rotary drive shaft having a first end portion on which an impeller is secured and to which the flexible drive shaft is connected. A vacuum chamber is provided in the housing over the impeller and the rotary shaft extends therethrough. The vacuum chamber has an inlet port laterally offset from the rotary shaft. A removable filter bag is mounted within the housing between the port and the vacuum tube.In one embodiment the cutting device includes a handpiece having a rotary bur. The shroud is a tubular member having a flared open mouth. The handpiece is releasably secured within the shroud, with the abrading bur extending from the interior of the shroud to slightly outside the flared mouth.
