  • Publication number: 20180325975
    Abstract: The present invention provides a prophylactic and/or therapeutic agent for non-alcoholic fatty liver disease (NAFLD), and particularly non-alcoholic steatohepatitis (NASH) comprising an ume (Japanese apricot) juice concentrate or a processed product thereof. The prophylactic and/or therapeutic agent is obtained by utilizing a component contained in a plant or a processed product thereof, and hence is safe and easily taken. It has been confirmed that when the ume juice concentrate or the processed product thereof is orally administered to a streptozocin (STZ)-induced NAFLD model mouse or an STZ-induced NASH model mouse, liver fibrogenesis can be reduced.

  • Publication number: 20180201890
    Abstract: When mammal cells are administered by using a container whose surface in contact with the mammal cells is formed of a fluororesin material at least partially having a —CF3 terminal group or a container whose surface in contact with the mammal cells is formed of a fluororesin material having a total number of non-fluorinated group terminals and —CF2H group terminals in the fluororesin of 70 or less per 1×106 carbon atoms, or mammal cells are stored or cultured in such a container, the cell adhesion on the container inner surface and the cell survival rate reduction can effectively be suppressed. Therefore, by using these containers, a mammal cell-containing liquid having a high concentration and a high proportion of living cells can be administered, stored or prepared, which contributes to regenerative medicine using the mammal cell-containing liquid (suspension liquid).

  • Patent number: 9884149
    Abstract: An object of the present invention is to provide an infusion preparation in which the Maillard reaction between an amino acid and a reducing sugar does not occur during storage and the size of fat particles in the fat emulsion does not increase during storage, and in which various types of vitamins can be incorporated in a stable manner, in spite of the fact that it is a two-chamber infusion preparation. Furthermore, even if only one of the infusions (of the infusion preparation) is administered, the patient is unlikely to develop hyperkalemia, vascular pain, or phlebitis. The present invention provides an infusion preparation containing two chambers separated by a partition that can be communicably opened, wherein a first chamber contains a first-chamber infusion containing a sugar and a fat emulsion, a second chamber contains a second-chamber infusion containing an amino acid and an electrolyte, the first-chamber infusion is substantially free of potassium, and has a relative osmotic pressure of 2.0 to 3.
