摘要: 应用半定量RT-PCR方法,测定了9种中药成分对小鼠脾脏T细胞IL-2mRNA水平的影响。结果显示,体内注射黄芪多糖、淫羊藿多糖、当归多糖、蜂胶黄酮和黄芪皂甙能够使ConA诱导的小鼠脾T细胞IL-2mRNA水平显著升高,蜂胶多糖、板兰根多糖、人参皂甙、淫羊藿黄酮不能影响细胞内IL-2mRNA丰度;中药成分体外诱导时与体内应用时的作用效应相同,但与对照相比较,蜂胶多糖在体外能够显著促进IL-2mRNA的诱生,与体内不同。

Abstract: In this study, the IL-2 mRNA levels of T lymphocytes in normal mice stimulated by nine Chinese herbal medicinal ingredients(CHMIs) were measured with a reverse transcription and semi-quantification polymerase chain reaction. The results showed that astragalus polysaccharide(APS), epimedium polysaccharide(EPS), Chinese angelica polysaccharide(CAPS), propolis flavone(PF)and astrogaloside(AS) promoted IL-2 mRNA levels in T lymphocytes in vitro and in vivo in different degrees, and the level of IL-2 mRNA induced by propolis polysaccharide(PPS) in vitro was higher than that of the control, which differed from that of PPS in vivo.
