Quantitative evaluation of the M1 and M2 macrophage/microglia. By immunofluorescence staining, most iNOS or Arg1 were expressed in ED1 positive cells. In LBP-pre groups at 7 d and 14 d, there were elevated ED1 expression, increased ED1⁺iNOS⁺ cells and reduced ED1⁺Arg1⁺ (M2) cell, in comparison to the controls. LBP-pre treated animals showed an increased number of M2 cells. Bar = 20 μm.
