Total cell counts in BALF of SEA group were much higher than that of control group (SEA group vs. control group: 56.3±3.172 vs. 2.31±0.143; #, P=0.010) and CAM group (SEA group vs. CAM group: 56.3±3.172 vs. 13.22±1.046; *, P=0.019). Each group cells were counted to compare the proportions of different cell types. A total of 200 cells were counted and the four different cell types were calculated as Figure 3B showed. Macrophages (Mac) in SEA group had the lowest number in comparison to control group and CAM group (#, SEA group vs. control group: 64.4±3.48 vs. 162.2±5.036, P=0.014; SEA group vs. CAM group: 64.4±3.48 vs. 132.464.4±5.352; *, P=0.026). Eosinophils (Eos) in OVA group accounted for a large part; in SEA group, there was significant difference when compared to control group and CAM group (SEA group vs. control group: 44.2±2.040 vs. 0.8±0.749; #, P=0.027; SEA group vs. CAM group: 44.2±2.040 vs. 34.2±3.060; *, P=0.042). While neutrophils (Neu) in SEA group were dramatically higher than that in control group (SEA group vs. control group: 68.0±1.424 vs. 28.2±5.418; #, P=0.035) and CAM group (SEA group vs. CAM group: 68.0±1.424 vs. 26.8±2.401; *, P=0.022).
