The results in Figure 5 showed that the cytokines including interleukin-2 (IL-2), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) secreted by splenocytes in CY-treated mice were lower than those in normal animal (p < 0.01). However, there was a dose-dependent increase of cytokines production after AHG administration in CY-treated mice. More interestingly, the 10 mg/kg AHG provided obvious promotion and strengthening of cytokines (IL-2, IFN-γ, TNF-α and IL-4) secretion (p < 0.01), and led to slight increases versus values seen in the normal control mice.
