Calycosin attenuates severe acute pancreatitis-associated acute lung injury by curtailing high mobility group box 1 - induced inflammation

Figure 4 The effect of calycosin on the immunological staining of lung slices for Ly6G. A: Micrographs of lung section stained with immunological staining of lung slices for Ly6G (brown); B: Average optical density for Ly6G was determined; C: Levels of myeloperoxidase in per milligram lung tissue were determined by enzyme-linked immunosorbent assay kits. Data represent mean ± SD values. ^aP < 0.001 vs L-arg group; ^bP < 0.01 vs L-arg group; ^cP < 0.05 vs L-arg group. Con: Control group; Cal: Calycosin group; L-arg: L-arginine group.
