Effect of walnut polyphenol extract (WPE) on cytotoxicity in splenocytes exposed to malathion/chlorpyrifos (MT/CPF). Splenocytes were treated with (A) MT (10−7–10−4 M); (B) CPF (10−7–10−4 M); (C) WPE ((1, 5, and 10 µg/mL) or MT (10−5 M) or different concentrations (1, 5, and 10 µg/mL) of WPE together with MT; (D) WPE (1, 5, and 10 µg/mL) or CPF (10−5 M) or different concentrations (1, 5, and 10 µg/mL) of WPE with CPF; (E) MT (10−5 M) or different concentrations (1, 5, and 10 µg/mL) of WPE or ellagic acid or proanthocyanidin or quercetin with MT; (F) CPF (10−5 M) or different concentrations (1, 5, and 10 µg/mL) of WPE or ellagic acid or proanthocyanidin or quercetin with CPF. Cell viability was evaluated by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. EA, ellagic acid; PC, proanthocyanidin; QUE, quercetin. Results are presented as mean ± SD of three separate experiments. * p < 0.05 or ** p < 0.01 vs. untreated control; # p < 0.05 or ## p < 0.01 vs. MT or CPF treatment.
