Fig. 2: Intracellular and extracellular concentrations of NO (as determined by Griess assay) in resting and ECNs-stimulated (24 h) A549 (Panel A) and BV-2 (Panel B) cells.

Data are the mean of four independent experiments. Standard deviations are represented by vertical bars. *Significantly different from resting (control) cells, p < 0.001
