Effect of iloprost (100 ng ml−1) on O2•− formation by cultured PAVSMCs and PAECs derived from pig PA after a 16-h incubation with (a) 1 μg ml−1 LPS, (b) 10 ng ml−1 IL-1α, (c) 10 ng ml−1 TNF-α or (d) 10 nM U46619. Data = mean±s.e.m., n=6. *P< 0.05; comparing controls to LPS, cytokine or U46619 induced levels in the absence of iloprost. $P<0.05; comparing LPS, cytokines or U46619 treated in the presence of iloprost to those in the absence of iloprost.
