TNF and preterm premature rupture of the membranes: reported that mean IL-8 levels in cord blood and mothers’ serum were significantly higher in the PPROM group (p < 0.001, p< 0.005); IL-6 levels found in mothers’ serum were significantly higher than those found in the control group (p < 0.01), but levels of IL-6 in UCB were similar (p > 0.05); TNF-a levels were also similar in both groups (p > 0.05) (Satar et al., 2008).
