The effect of P vulgaris on mice serum concentrations of cytokines.
The serum levels of IL-1β, IFN-γ, IL-4 and IL-10 in P. vulgaris exact treated (0.00, 0.15, 0.30, 0.90 g/kg BW) mice for 30 days were detected by ELISA according to the manual of ELISA kits. The data were expressed as mean±SD of each group (n = 10 per group). No significant difference in serum levels of IL-1β (Fig. 2.A), IFN-γ (Fig. 2B), IL-4(Fig. 2C) and IL-10 (Fig. 2D) was observed among these four groups of mice (p>0.05).
