Effect of Survanta®on cell toxicity and cell number. Subconfluent (80%) cultures of human lung epithelial BEAS-2B cells were exposed to various concentrations of Survanta® and, at one and two days after the treatment, cells were analyzed for cytotoxicity and cell number by LDH assay (A) and cell counting (B). Plots are mean ± S.D. (n = 4). No significant changes over non-treated controls were observed in all measurements at p < 0.05.
