  • Patent number: 7579381
    Abstract: The present invention provides methods for treating tissue to inhibit post-implant calcification of a biological tissue. In one method of this invention, a tissue is immersed in or otherwise contacted with a pretreated glutaraldehyde solution, i.e., a heat-treated or pH-adjusted glutaraldehyde solution. The tissue may be partially fixed with glutaraldehyde prior to, after, or concurrently with the step of contacting the tissue with the pretreated gluteraldehyde. Contact with the pretreated gluteraldehyde produces free amine groups on the tissue, which are subsequently blocked by contacting the crosslinked tissue with a blocking agent. In another embodiment, a tissue is contacted with either a non-pretreated glutaraldehyde or a pH-adjusted glutaraldehyde solution for a period of time sufficient to crosslink the tissue. The crosslinked tissue is then treated with a reducing agent that reduces aldehyde and carboxylic acid groups on the fixed tissue.

  • Patent number: 5004757
    Abstract: Very potent, stable, ordorless, and phenol-free virciudal solutions are active at high dilution when used for surface decontamination of animate and inanimate objects. The virucidal compositions described are efficacious in a matter of minutes against both the lipophilic and the more resistant hydrophilic viruses. The three active ingredients in these virucidal compositions are the glutaraldehyde monomer in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an anionic surfactant of the alkyl sulfate, alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A preferred anionic surfactant would be the Sodium Dodecyl Sulfate (SDS), which exhibits strong cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde aqueous solutions (0.0025%). Improved virucidal killing at higher dilutions of the same formula were observed with the more resistant Coxsackie B viruses.

    Abstract: Composition for use as a pulpotomy agent having glutaraldehyde as the active ingredient in a solution stabilized by a buffer suitable for maintaining the pH of the glutaraldehyde solution at near-physiological levels. The stable composition also includes the anti-oxidants sodium nitrite and glycerol. The composition is used by direct application to infected coronal pulp tissue to fix the tissues and prevent further deterioration caused by pulpitis. A method of treating the infected tissue prior to dental restoration is also disclosed.

  • Patent number: 4784790
    Abstract: In the cleaning and disinfection of endoscopes, the endoscope surfaces to be cleaned are successively(a) brought into contact with a cleaning solution which is heated to 55.degree. to 65.degree. C., kept at that temperature for 1 to 15 minutes and then drained off and which contains a low-foam nonionic surfactant, a proteolytic enzyme, at least one complexing agent and, optionally, other standard detergent constituents, and has a pH value of from 6 to 8;(b) brought into contact with a disinfectant solution which is heated to 55.degree. to 65.degree. C., kept at that temperature for 1 to 15 minutes and then separated off and which contains an aldehyde selected from the group consisting of formaldehyde and aliphatic C.sub.2 -C.sub.8 dialdehydes and at least one complexing agent, and has a pH value of from 6 to 8;(c) washed at least twice with water of which the pH value is adjusted to pH 6-8, the water being heated to 55.degree. to 65.degree. C.

  • Patent number: 4784844
    Abstract: The present invention provides silicone-water emulsions formed from volatile cyclic polysiloxanes which are emulsified with a preblended mixture of water and a combination of emulsifying agents. Highly ethoxylated nonionic emulsifying agents are particularly well-suited for the formation of stable silicone-water emulsions from volatile cyclic polysiloxanes. These volatile silicone-water emulsions can be combined with epidermal enhancing agents for cosmetic and medicinal purposes.

  • Patent number: 4675327
    Abstract: Embalming preparations, which are far less noxious than previously known compositions, comprise a combination of a disinfectant and a plant growth regulating compound. The compositions achieve anti-microbial potency at concentrations of these ingredients far lower than the concentration levels of disinfectants found in known embalming preparations.
