摘要: 为了研究黄芩苷、连翘酯苷对大鼠肺微血管内皮细胞(pulmonary microvascular endothelial cells,PMVECs)分泌IFN-α、IFN-γ的影响,本试验以体外培养的PMVECs为模型,用ELISA法检测这2种中药成分在不同浓度、不同时间点诱导PMVECs分泌IFN-α和IFN-γ的量。结果表明,黄芩苷在10 μg/mL,24 h时诱导PMVECs分泌的IFN-α和IFN-γ的量均最高,连翘酯苷分别在20 μg/mL、12 h时和5 μg/mL、24 h时诱导PMVECs分泌的IFN-α和IFN-γ的量最高。这一结果为体外筛选诱导PMVECs表达干扰素的中药成分提供了参考,为进一步研究中药成分的抗病毒机理奠定了基础。

Abstract: To study the effect of baicalin and forsythiaside to induce rat pulmonary microvascular endothelial cells to express IFN-α and IFN-γ, the model was based on cultured PMVECs in vitro. With the method of ELISA, we detected the secretory volume of IFN-α and IFN-γ after PMVECs was induced by baicalin and forsythiaside at different concentration and time. The results indicated that PMVECs produced the most IFN-α and IFN-γ after induced 24 h by baicalin at 10 μg/mL, while forsythiaside was 20 μg/mL at 12 h and 5 μg/mL at 24 h, respectively. The result provided references for screening Chinese herbal medicinal constituents that could induce PMVECs to express IFN, and laid the foundation to further study the anti-virus mechanism of medicinal constituents.
