In vitro effect of CWE on the viability of macrophages. Peritoneal macrophages from thioglycollate-injected mice were isolated and treated with varying concentrations of CWE for 24 hours with or without LPS (100 ng/ml). Cell viability was measured by the MTT assay. Control: cells without CWE ( 0 μg/ml). Data are expressed as the mean ± SD of two independent experiments.
