  • Patent number: 10300085
    Abstract: A nutrient composition, a lipid metabolism-improving agent, and prophylactic and/or therapeutic agents typically for inflammatory bowel diseases, immune disorders, cancers, non-alcoholic steatohepatitis, obesity, diabetes, and hypercholesterolemia each contain a cellulose acetate having a total degree of acetyl substitution of 0.4 to 1.1. The cellulose acetate may be one having a compositional distribution index (CDI) of 2.0 or less, where the CDI is defined by the formula: CDI=(Measured value of half height width of chemical composition)/(Theoretical value of half height width of chemical composition) where the measured value of half height width of chemical composition represents a half height width of chemical composition determined by HPLC analysis of a cellulose acetate propionate prepared by propionylating all residual hydroxy groups of the cellulose acetate (sample), and the theoretical value of half height width of chemical composition =2.

  • Patent number: 10058590
    Abstract: The invention presents a therapeutic agent (and progress suppressant) for amyotrophic lateral sclerosis (ALS) containing HGF and/or HGF gene as active ingredient. HGF has an effect of improving the motor function of ALS and life span through two actions, that is, direct neuronutrient factor activity on motoneurons, and indirect improving action of glutamate cytotoxicity on motoneurons by maintaining the level of glutamate transporter in astrocytes. Hence, HGF and/or HGF gene can be used as an effective therapeutic agent not known in the past.
