陆皂苷甲对小鼠胸腺细胞凋亡的影响

Effect of esculentoside A on apoptosis of mouse thymocyte

目的 :研究商陆皂苷甲 (Es A )对小鼠胸腺细胞的凋亡效应的影响。方法 :采用电镜、DNA琼脂糖凝胶电泳和流式细胞仪三种分析方法 ,测定 Es A对小鼠胸腺细胞的凋亡效应的影响。 结果 :Es A在 2 .5～ 10μg/ ml的浓度范围内 ,对小鼠胸腺细胞自发出现的细胞凋亡无影响 ,但能显著地促进 Con A活化的胸腺细胞的凋亡。 结论 :Es A有促进 Con A活化的胸腺细胞凋亡的作用 ,显示商陆皂苷甲对细胞免疫有调节作用。

Objective:To investigate the effect of esculentoside (EsA) on apoptosis of murine thymocyte. Methods:Using electronic microscope, DNA agarose electrophoresis and flow cytometry analysis,the effect of EsA on apoptosis of murine thymocyte was examined. Results:The result showed that apoptosis of activated thymocyte by ConA was markedly promoted by 2.5, 5, 10 μg/ml EsA in murine thymocyte culture for 3 h, but the spontaneous apoptosis was not affected by EsA. Conclusion:The results suggest that EsA has the positive effect on apoptosis of activated murine thymocyte.
