In vivo effects of feeding mushrooms. C57BL/6 mice were fed control diet only or control diet that contained 2% WB freeze dried mushrooms. (A) Weights of the WB fed mice gained weight over the 4 weeks of the study. Values are mean ± SEM with 6–10 mice per group. (B) IL-10 and (C) IFN-γ production of Con A and LPS stimulated splenocytes from 1% WB fed, 1% oyster fed and control (Ctrl) fed mice. Values are mean ± SEM with 3–5 mice per group.
