Figure 1. Viral titers of DEV at growing conditions with different concentrations of resveratrol.

(A) DEFs were infected with DEV (TCID₅₀) and then treated with resveratrol. After incubation for 72 h, the supernatants were collected and analyzed for TCID₅₀ values. Values are means ± SD (n = 3). Significance: *P<0.01 vs. non drug treated control group. ^a TCID₅₀ >9. (B) DEFs were first infected with DEV (TCID₅₀) and then treated with resveratrol. After incubation for 72 h, MTT assay was performed, and the results were expressed as percent of inhibition in drug-treated cultures compared with untreated group. Values are means ± SD (n = 3).
