Abstract
Polysaccharides produced in microorganisms and plants are known to increase the immune response in the body. We proposed analysis of beta-glucan contents of phellinus linteus fruit body (FB) and mycelium (MC) cultured in cudrania tricuspidata . Also, we examined whether fruit body and mycelium can increase the immune response in cyclophosphamide-induced immunosuppression animal models. We injected cyclophosphamide (50 ㎎/㎏) twice to produce immunosuppression mice. Then, FB (200 ㎎/㎏) and MC (200 ㎎/㎏) were oral administered for 14 days. In order to confirm the immune-enhancing effect of FB and MC, we analyzed spleen weight, the number of immune cells, cytokines, and immunoglobulins levels. Cyclophosphamide decreased the weight of spleen, the number of immune cells. However, FB and MC have significantly increased the weight of spleen, the number of white blood cell, lymphocyte and monocyte. In addition, they have significantly increased immune-related cytokines (IL-2 and IFN-γ) and immunoglobulins (IgA, IgG, IgM) levels. As a results, phellinus linteus fruit body (FB) and mycelium (MC) cultured in cudrania tricuspidata can be used as effective natural materials for immune-enhancing.
