TNF and hydrops fetalis: In comparison to the lungs from the LF (Fig. 3a-c) and HF (Fig. 3g-i) control animals, we observed a significant increase in TNF- α in the lungs from both the LF DEP (Fig. 3d-f, p = 0.001) and HF DEP (Fig. 3j-l, p < 0.001) groups, F = 42.48 for exposure, as quantified in Fig. 3m.
