Fig 4. Oxidative stress produced by resveratrol in trophozoites.

A) ROS production in trophozoites untreated or treated with IC₅₀ resveratrol. Quantification was performed by flow cytometry using the DCFDA reagent. B) Lipid peroxides in total lipids of trophozoites. 0.4% ethanol- and 0.5 mM H₂O₂-treated trophozoites were used as controls. Values represent the mean ± standard error of three independent experiments. ***p<0.001.
