Figure 4.

Expressions of IL-6, IFN-γ, TNF-α, and iNOS mRNA in the uterus quantified with real-time PCR. β-Actin was used as a reference gene. Data are presented as means and SEM (n = 6). Values with no letters or the same superscripts are not significantly different, whereas those with different superscript letters are significantly different (P < 0.05). IFN-γ, interferon-γ; IL-6, interleukin-6; iNOS, inducible nitric oxide synthase; LPS, lipopolysaccharide; OCR, organic chemical reagent; TNF-α, tumor necrosis factor-α.
