PURPOSE:To obtain an immunological competence-activating substance used for improving human immunological competence regarded as readily administrable with being solubilized in water comprising an enzyme-treated material of euglena. CONSTITUTION:The aimed immunological competence-activating substance is composed of an enzyme-treated material of euglena or an enzyme-treated material or a hydrolysis-treated material with an acid of paramylon extract as a component of euglena. The enzyme in said treatment is preferably protease or beta-1,3 glucanase and the acid is preferably hydrochloric acid, acetic acid, phosphoric acid or sulfuric acid. The paramylon-treated material having 5000-2000000 molecular weight is preferable in a viewpoint of a slight reduction of activity and being solubilized in water. |
