Immunostimulatory effects of Mc-fEE in vivo by promoting NK cell activities. a Specific lysis levels of YAC-1 cells by activated NK cells from Mc-fEE-treated mice spleens were measured by cell-mediated LDH assay. b Relative mRNA expression levels of IL-1β, IFN-γ, and TNF-α were detected from Mc-fEE-treated mice splenocytes using quantitative real-time PCR. The data are expressed as mean ± SD (n = 3) with an additional experiment under same conditions. *: p < 0.05, **: p < 0.01 compared to the normal group
