a The comparison of scavenger receptor A (SRA) expression in various time points (IHC) mcp/HP. Compared among acute obstructive cholangitis (AOC) group, Bile Duct Ligation (BDL) group and Sham Operation (SO) groups, *P < 0.01, ^△P < 0.05; compared with same group, ^#P < 0.01. b Kupffer cells’ SRA expression in acute obstructive cholangitis (AOC) groups at 0 h (SP × 400). The brown positive products of SRA expression are mainly located on the surface of Kupffer cells and diffusely distributed in liver tissue. c–f Kupffer Cells’ SRA expression in liver tissue in acute obstructive cholangitis (AOC) group at 3, 6, 12, 24 h (SP × 400). SRA expression products reduce with prolonged experimental time
