The results showed that astragalus polysaccharide （APS）, epimedium polysaccharide （EPS）, Chinese angelica polysaccharide （CAPS）, propolis flavone （PF）, and astrogalosides （AS） promoted IL-2 mRNA levels in T lymphocytes in vitro and in vivo to differing degrees, and the level of IL-2 mRNA induced by propolis polysaccharide （PPS） in vitro was higher than that induced by the control, which differed from that of PPS in vivo.展开更多
