Effects of t-TUCB and Rolipram on pulmonary inflammatory cytokines. Inflammatory cytokine (A) IL-1β, (B) IL-6, (C) IFN-γ, and (D) IL-12p70 concentrations in whole-lung homogenate are reported. Data are expressed as mean ± SEM for 4–8 animals/group. *P < 0.05, TS-exposed groups were significantly different from the control group. †P < 0.05, treatment group with sEHI t-TUCB was significantly different from the TS vehicle group.
