METHOD OF PROTECTING LIVING BODY FROM FOREIGN FACTOR AND COMPOSITION THEREFOR

摘要

The objective is to provide a composition or a food material for protecting a living body from an external factor, which includes an extract from Agaricus Blazei Murill. The composition protects a living body through immunocompetent cells. The immunocompetent cells may be macrophages, and optionally, T cells. The immunocompetent cells may be antibody producing cells. The composition may protect a living body through an enhancement of humoral immunity. The enhancement of the humoral immunity may be caused by activating lymphocytes selected from the group consisting of activating T cells and macrophages, and thus enhancing expression of interleukin selected from the group consisting of interleukin-1 beta and interleukin 6. The external factor may be taken by smoking, or may be an antigen substance.
