Effects of 100 μg/mL silymarin on the attachment and entry of EV-A71 to Vero cells. a The viral attachment inhibition was calculated as the number of plaques formed by the silymarin-treated virus over the number of plaques formed by the untreated virus. b Viral entry inhibition was calculated as the number of plaques formed by the virus treated with silymarin after attachment to the cells over the number of plaques formed by the untreated virus. Data presented as mean ± S.E.M. Error bars indicate the range of values obtained from three independent experiments. *** p < 0.001 indicates a significant difference in between groups compared by t-test
