Astragalus polysaccharide, as one kind of biological macromolecule extracted from Astragalus, has antiviral activities. IC50 value: Target: In vitro: Adding astragalus polysaccharide before PCV2 infection decreased significantly PCV2 DNA copies, the number of infected cells, MDA level, ROS level and NF-κB activation in PK15 cells and increased significantly GSH contents and SOD activity compared to control without astragalus polysaccharide [1]. H2O2 induced oxidative damage in MRC-5 cells in a concentration-dependent manner. We chose the oxidative damage model induced by 800 μmol/L H2O2 for 24 hours to further study the protective mechanism of APS. Compared with H2O2 control groups, 200 mg/L APS significantly increased the protein level of APE/Ref-1 and TRX, decreased the content of 8-OHdG and the apoptosis of MRC-5 cells, and improved dramatically the cell viability [2]. In vivo: Spragne-Dawley rats were treated with astragalus polysaccharide (0.5 g/kg/day, once daily), astragalus polysaccharide administration enhanced the expression of T-bet (P=0.04) and GATA-3 (P=0.019) in comparison to TNBS group, and resulting in an up-regulated GATA-3/T-bet ratio [3].
