AGENT FOR PREVENTING DEVELOPMENT OF PRION DISEASE, FOOD ADDITIVE AND FEED ADDITIVE COMPRISING THE SAME

摘要

There has been found no substantially effective method for treating/preventing prion diseases which are neurological diseases caused by impairment of central nervous system by prion (i.e., abnormal prion protein), including Creutzfeldt-Jakob disease (CJD), Gerstmann-Straussler-Scheinker syndrome (GSS), scrapie in animals, bovine spongiform encephalopathy (BSE) and chronic wasting disease (CWD). Then, it is intended to provide an agent for preventing the development of a prion disease, a food additive and a feed additive having inhibitory effect on the proliferation of abnormal prion protein by utilizing a natural food material ingested orally in daily life. The agent comprises fucoidan as an active ingredient. The food additive or feed additive comprises the agent.
