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

Figure 5 Astragalus polysaccharides combined with matrine relieve inflammatory response and oxidative stress injury in lung tissues of rats with ulcerative colitis. A and B: Tumor necrosis factor-α (A) and interleukin-1β levels (B) in lung tissues in various groups detected by enzyme-linked immunosorbent assay (ELISA); C-E: Activities of superoxide dismutase (C), malondialdehyde (D), and myeloperoxidase (E) in lung tissues in various groups determined with commercial detection kits. ^aP < 0.05 and ^bP < 0.01 vs normal group; ^cP < 0.05 and ^dP < 0.01 vs model group. APS: Astragalus polysaccharides; TNF-α: Tumor necrosis factor-α; IL-1β: Interleukins-1β; MPO: Myeloperoxidase.
