Fig. 1From: HS-GC–MS analysis of volatile organic compounds after hyperoxia-induced oxidative stress: a validation studyHyperoxia-induced cytotoxicity of A549 cells. Relative fold change of interleukin-8 (A) and lactate dehydrogenase (B) supernatant concentrations of control, hyperoxia-exposed and H2O2-exposed cells in comparison to the levels before experimental exposure are shown. Differences were tested by Dunn’s test with Holm’s correction for multiple comparisonsBack to article page
