After Eq administration, the jejunal TNF-α and IL-10 concentrations and ileal TNF-α concentrations were lower (p < 0.05) in the IUGR + Eq group than those in the IUGR group, while no differences (p > 0.05) were observed in the jejunal and ileal IFN-γ and IL-4 concentrations among treatments. The gene discussed is IL4; the disease is fetal growth restriction.
