RESUMO
Objective :To investigate the effects of ethanol precipitate(ET-Pre) and RNA of Grifola frondosa on non-specific immunity in mouse.Methods:The common biological methods were used to examine the levels of cytokines and immunocyte activity. Results: The killing activity of the NK cells, the phagocytosis function of macrophages and the levels of TNF?/IL-1 in the animals treated with ET-Pre and RNA respectively were significantly higher than those in the control.The RNA was stronger than ET-Pre in increasing killing activity of NK cells and phagocytosis function of macrophages. Conclusion:Both ET-Pre and RNA extracts of Grifola frondosa may promote immunoactivity nonspecifi-cally and inhibit tumor cells indirectly.
