Figure 2 Chlorogenic acid (CGA) reduced the infiltration of differential inflammatory cells in nasal lavage fluid (NALF) and prevented epithelial cells disruption. NALF was collected immediately after sacrifice, and the cells were isolated by cytospin. (A) Cells from different groups were stained by Diff-Quick. Red arrows indicate eosinophils. Black arrows indicate epithelial cells lost from inflammatory tissues. (B) The number of total cells in NALF. (C) The number of eosinophils in NALF. (D) The number of neutrophils in NALF. (E) The number of lymphocytes in NALF. (F) The number of macrophages in NALF. Scale bar: 25μm, ×400 magnification. n=10 per group. ### P<0.001 vs. control, *** P<0.001 vs. OVA.
