  • Patent number: 10456433
    Abstract: Provided are an inhibitor, a prophylactic, and a therapeutic agent for rheumatoid arthritis that have no side effects and that can correct immune abnormality associated with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent for rheumatoid arthritis contain a Euglena-derived material as an active ingredient. The inhibitor, the prophylactic and the agent are used as an antirheumatic drug for controlling the activity of rheumatoid arthritis by alleviating immune abnormality associated with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent are also used for a living individual who has not been definitively diagnosed with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent are continuously administered to the living individual from any point before definitive diagnosis of rheumatoid arthritis to any point after the definitive diagnosis.

  • Patent number: 10231989
    Abstract: Provided are a novel renal failure progression inhibitor, prophylactic agent for renal failure, and indoxyl sulfate production inhibitor, intended for human use, in particular, for a patient with renal failure. The renal failure progression inhibitor, prophylactic agent for renal failure, and indoxyl sulfate production inhibitor each comprises paramylon derived from Euglena or a processed product thereof as an active ingredient. In the case of the renal failure progression inhibitor, for example, paramylon is continuously orally administered to a patient suffering from chronic renal failure, undergoing a dialysis therapy, several times per day in a dose of 1 to 5 g per intake. In particular, the renal failure progression inhibitor is singly administered to the patient in a capsule or powdered preparation at a prescribed time interval before and after administration of other drugs.

  • Patent number: 10117901
    Abstract: Provided are a prophylactic or therapeutic agent for a peptic ulcer, a food additive for prevention and treatment of a peptic ulcer, an iNOS expression inhibitor, and a COX-2 expression inhibitor, all of which have little side effects. The prophylactic or therapeutic agent contains a Euglena-derived material as an active ingredient. The Euglena-derived material may be Euglena, paramylon, or an acid-treated paramylon. The prophylactic or therapeutic agent is useful for the prevention or treatment of a peptic ulcer induced by psychological stress. The peptic ulcer may be a gastric ulcer. The food additive contains a Euglena-derived material as an active ingredient.

  • Publication number: 20170020939
    Abstract: The present invention provides a novel immune balance regulator that regulates an immune balance in a living body. The immune balance regulator contains a Euglena-derived material and regulates an immune balance between Th1, Th2, and Th17, which is a balance between immune responses individually induced by Th1, Th2, and Th17 in a living body. The immune balance regulator regulates the immune balance between Th1, Th2, and Th17 so that immune responses induced by Th1 become relatively dominant over immune responses induced by Th2 or Th17 to improve a physical constitution that has an immune imbalance of Th1, Th2, and Th17 shifted towards Th2 and to prevent or treat a disease associated with the immune imbalance of Th1, Th2, and Th17 shifted towards a Th2 dominance. The immune balance regulator is administered prior to expected onset of a disease associated with the immune imbalance of Th1, Th2, and Th17 shifted towards the Th2 dominance.
