  • Patent number: 9895331
    Abstract: An object of the present invention is to provide a preventive and/or therapeutic agent for radiation damage that has a novel mechanism of action and can prevent and alleviate a wide range of symptoms of radiation damage for which no therapeutic measures have been available so far, and moreover, is highly safe to humans. A preventive and/or therapeutic agent for radiation damage comprising a compound represented by the following formula (I) such as 5-aminolevulinic acid (5-ALA) or a salt thereof as an active ingredient can be used to improve the survival rate, improve body weight reduction, and alleviate hematopoietic disorder: (wherein R1 represents a hydrogen atom or an acyl group; and R2 represents a hydrogen atom, a linear or branched alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group).

  • Patent number: 9723991
    Abstract: An apparatus and method for photodynamic therapy or photodynamic diagnosis using an illuminator comprising a plurality of light sources generally conforming to a contoured surface and irradiating the contoured surface with substantially uniform intensity visible light. The light sources may comprise generally U-shaped fluorescent tubes that are driven by electronic ballasts. The spacing of the U-shaped tubes is varied to increase the output at the edges of the illuminator to make the output more uniform. Also, different portions of the tubes are cooled at different amounts, to improve uniformity. A light sensor monitors output from the U-shaped tubes to provide a signal for adjusting the output from the tubes.

  • Patent number: 9572881
    Abstract: Halo-organic heterocyclic compounds are described, in which at least two halogen atoms are bound to a nitrogen-containing heterocyclic terminal moiety of the compound, with at least one of such halogen atoms being iodine or bromine. Also described are polymethine dyes based on these heterocyclic compounds, and dendrimeric compounds and conjugates of such polymethine dyes. The polymethine dyes are characterized by enhanced properties, e.g., brightness, photostability, sensitivity and/or selective affinity that make them useful to target cancer cells, pathogenic microorganisms, and/or other biological materials, in applications such as photodynamic therapy, photodynamic antimicrobial chemotherapy (PACT), cancer treatment, selective removal or attachment of biological materials, antimicrobial coating materials, and other diagnostic, theranostic, spectrum shifting, deposition/growth, and analytic applications.

  • Patent number: 7345092
    Abstract: A topical insecticide preparation is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. The topical insecticide contains a combination of a first pyrethroid insecticide effective for killing fleas, a second pyrethroid insecticide effective for killing ticks, and an insect growth regulator (IGR). The topical insecticide preparation can be packaged together or packaged so that the first and second pyrethroid insecticides are stored separately prior to administration of the insecticide preparation to the animal. The combination of the first and second pyrethroid insecticides with an insect growth regulator results in an insecticide preparation formulated to have enhanced insecticidal activity against fleas and ticks compared to the effectiveness of the first and second insecticides used alone.

  • Patent number: 6740637
    Abstract: Conjugates of chlorophyll (Chl) and bacteriochlorophyll (Bchl) derivatives with amino acids, peptides and proteins are provided by the invention. The amino acid, peptide or protein residue is linked to the 17-propionic acid group of a Chl or Bchl residue directly or through a chain. The conjugates are for use as photosensitizers in photodynamic therapy and in diagnostics of tumors. Conjugation with cell-specific ligands, such as hormones, growth factors or tumor-specific antibodies, will target the Chl or Bchl moiety to the tumor site. Thus, conjugates with melanocyte stimulating hormones are suitable for photodynamic therapy of melanoma tumors.

    Abstract: The invention relates to use of (a) compounds of phosphorus containing at least partly lipophilic organic radicals together with (b) urea and/or urea derivatives in selected quantity ratios of (a) to (b) as a soil additive for biologically controlling plant-parasitic soil nematodes by strengthening the correspondingly antagonistic soil potential, more particularly by strengthening the growth of antagonistic and/or nematicidal rhizosphere bacteria and/or corresponding mycorrhiza strains—and at the same time strengthening the growth of cultivated plants in soil. The multicomponent mixtures which strengthen bacterial growth are preferably introduced into the region of the plant roots in the form of an aqueous preparation using plant-compatible emulsifiers before and/or during plant growth. Components (a) and (b) are used in such quantity ratios that the ratio by weight of C to N is no higher than 6:1 and preferably no higher than 5:1.
