Baicalein inhibits leukocyte infiltration in radiation-induced enteritis. (A) Attachment of elastase-positive neutrophil in the mesenteric vessels in the intestine of control (Con), irradiated (IR), and baicalein-treated IR (IR+Bai) mice at 6 days after radiation exposure. Immunohistochemistry of (B) myeloperoxidase (Mpo) and (C) neutrophil elastase for neutrophil detection, and (D) Congo red stain for eosinophil detection in the intestine of Con, IR, and IR+Bai mice. Red arrowhead indicates Mpo- and elastase-positive neutrophils. Yellow arrowhead indicates eosinophil. (E) Eosinophil counting in the intestine of Con, IR, and IR+Bai mice. Bar = 100 μm. Data are presented as the mean ± standard error of the mean; n = 5 mice for each group. *P < 0.05 compared to the control; # P < 0.05 compared to the IR group.
