Figure 3: Cell viability in human umbilical vein endothelial cells pretreated with Thymelaea microphylla acetone extract (20–40 μg/ml) for 24 h and then exposed for 2 h to tumor necrosis factor-α (20 ng/ml). Cultures treated with the vehicle alone (dimethyl sulfoxide 0.1%) were used as controls. Data represent percentage of viable cells (mean percentage) calculated from the number of viable cells in treated samples versus control untreated and unexposed. *P < 0.05 versus respective tumor necrosis factor-α 0 ng/ml; §P <0.05 versus vehicle exposed to tumor necrosis factor-α 20 ng/ml
