AD significantly decreased neutrophil infiltration. (A,B) Immunohistochemical analysis was performed to detect myeloperoxidase (MPO) (A) and neutrophil elastase (NE) (B) expression in the ankle joint tissue sections of each treatment group on day 37 (n = 10). Representative images are shown. (C,D) The air pouch assay showed that the AD (25 μM) treatment significantly suppressed lipopolysaccharide (LPS)-induced recruitment of total leucocytes (C) and neutrophils (D). The numbers of neutrophils and total leukocytes in the air pouch are expressed as means ± SD. ** p < 0.01 (n ≥ 5).
