The immune effects of edible fungus polysaccharides compounds in mice.

From the paper

Abstract

Most of the current researches on immune function of fungus polysaccharides were based on individual component. Only a few studies were involved in the mixture of proprietary compounds from different species of edible fungi. The main objective of this study was to evaluate mice's immune effects of the mixed polysaccharides (ratio 1: 0.5: 0.5) extracted from Lentinus edodes, Ganoderma lucidium and Grifola frondosa. Kunming mice weighted 20+/-2 g (10 mice/group) was treated for 30 consecutive days with polysaccharides compounds, which were added to basal diet at three concentrations: 0.17, 0.33 and 1.00 g/kg body weight. Then the NK cells' activities, ratio thymus/body and spleen/body, macrophage's activities, hemolysis, and delayed hypersensitivity (DTH) were determined by standard methods. Polysaccharides compounds at the concentrations of 0.33 and 1.00 g/kg body weight significantly increased the thymus and NK cells activities (p 0.05). The results indicated that the mixed polysaccharides compounds could enhance the cell immune of the mice.
