Abdominal paracentesis drainage ameliorates severe acute pancreatitis in rats by regulating the polarization of peritoneal macrophages

Figure 5 Number of M2 macrophages increases in the pancreas of abdominal paracentesis drainage rats and exerts anti-inflammatory effects. A: Pancreatic tissues from each group were stained with DAPI (blue), CD163 (green in upper two panels), CD86 (green in lower two panels) and CD68 (infrared represented by carmine). Representative images are shown; B and C: Protein levels of Arg-1, CD163, CD86 and iNOS in the pancreatic tissues of each group were measured by Western blot, and the relative expression of these proteins was normalized to GAPDH. Data are representative of at least three independent experiments. ^aP < 0.05 vs severe acute pancreatitis.
