H2S release from NaHS and ACS6 in vitro measured by the methylene blue assay, (a) concentration–response, (b) as a function of time. (c) H2S release from ACS6 in the absence or presence of pulmonary arterial endothelial cell (PAEC) lysates. Each point is the mean±s.e.mean, n=6. *P<0.01; significantly increased compared with ACS6 alone.
