Fig. 1From: Arsenic trioxide induces apoptosis and the formation of reactive oxygen species in rat glioma cellsThe inhibitory effects of As2O3 on the cell viability of C6 glioma cells, 9 L sarcoma cells and normal non-tumor (glial) cells (control). a The inhibitory rate was determined using the MTT assay 24, 48 and 72 h after exposure to As2O3 and it is expressed as % of control exposure at 24 h. b Cell viability was determined using the Trypan blue exclusion assay. *p < 0.05, **p < 0.01 vs. glial cellsBack to article page
