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
目前,国内尚无将体外转译体系应用于IL 2研究的报道。本文以长春1号小麦种制备麦胚无细胞体系,经与兔网织红细胞、腹水癌细胞两体系比较筛选,结果证明麦胚无细胞转译体系适于实验室应用。通过对ML A 144mRNA作转译活性鉴定,证明该系统...目前,国内尚无将体外转译体系应用于IL 2研究的报道。本文以长春1号小麦种制备麦胚无细胞体系,经与兔网织红细胞、腹水癌细胞两体系比较筛选,结果证明麦胚无细胞转译体系适于实验室应用。通过对ML A 144mRNA作转译活性鉴定,证明该系统可以合成具有生物活性的、完整的IL2分子。展开更多

文摘In this study, the IL-2 mRNA levels of T lymphocytes in normal mice stimulated by nine Chinese herbal medicinal ingredients （CHMIs） were measured using semiquantification reverse transcription polymerase chain reaction. 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.
