Effect of PGE on the plasma levels of immune-related cytokines in the sera of CP-induced immunosuppression rats. Rats were given saline, CP (5 mg/kg/day), and PGE (0, 10, 30, or 100 mg/kg/day) once daily for 28 days, after which the serum levels of TNF-α (a), IFN-γ (b), IL-2 (c), and IL-12 (d) were quantified using ELISA kits. Bars labeled with different superscripts have significantly different values (P < 0.05). Data are presented as the means ± standard errors (n = 7)
