Effects of SE on the recruitment of inflammatory cells in mouse lung tissue. a Histological examination of lung tissue was performed 24 h after the last OVA challenge. Lung tissues were fixed, sectioned at 4-µm thickness, and stained with H&E solution. b Scoring of the extent of inflammation by quantitative analysis of inflammatory cell infiltration in lung sections. Values are expressed as mean ± SE (n = 8). Means with the same letters are not significantly different at P < 0.05 using Duncan’s multiple-range test
