Synergistic protection of astragalus polysaccharides and matrine against ulcerative colitis and associated lung injury in rats

Figure 3 Astragalus polysaccharides combined with matrine inhibit diamine oxidase activity in rats with ulcerative colitis. A: Serum endotoxin levels in various groups detected by enzyme-linked immunosorbent assay; B: Serum diamine oxidase activity in various groups detected by spectrophotometry. ^aP < 0.05 and ^bP < 0.01 vs normal group; ^cP < 0.05 and ^dP < 0.01 vs model group. APS: Astragalus polysaccharides; ET: Endotoxin; DAO: Diamine oxidase.
