Eosinophil influx in BALF and lung.

(A) Total cell count in BALF of NaCl or HDM challenged vehicle (white bars) or C1-INH (black bars) treated mice. (B) Differential cell count in BALF showing eosinophil, neutrophil, macrophage, and lymphocyte numbers in NaCl challenged vehicle (dotted bars) and C1-INH treated (blocked bars) mice and in HDM challenged vehicle (white bars) and C1-INH treated (black bars) mice. (C) Influx of eosinophils in the lung was determined by digital analysis of Major Basic Protein (MBP) stained lung sections in C1-INH (black bars) and vehicle (white bars) treated mice following challenge with NaCl or HDM. Representative pictures of each group are shown, magnification 4x. Data are presented as mean ± SEM, n = 6 (NaCl) and n = 10 (HDM).
