In murine models of colitis induced by dextran sulfate sodium (DSS), baicalein treatment markedly lowers colonic levels of these cytokines, reduces neutrophil infiltration (as evidenced by decreased myeloperoxidase (MPO) activity), and improves histological damage scores (Zhang et al., 2017; Feng et al., 2014; Dou et al., 2012). Here, MPO is linked to colitis.
