[目的]研究DHA复合物抗肿瘤作用机理。[方法]以人胃癌细胞SGC-7901为模型,利用吖啶橙染色,荧光显微镜观察人胃癌细胞SGC-7901经DHA复合物治疗前后的形态,研究DHA复合物诱导人胃癌细胞SGC-7901的凋亡作用。[结果]实验发现:经DHA复合物治疗后,人胃癌细胞SGC-7901细胞核出现明显的凋亡核形态。[结论]DHA复合物具有明显诱导人胃癌细胞SGC-7901发生凋亡的作用。
[Objective] To study the anti-tumor mechanism of DHA complex. [Method] The human gastric cancer cell line SGC-7901 was used as a model to observe the morphological changes of human gastric cancer cell line SGC-7901 treated with DHA complex by acridine orange staining and fluorescence microscopy. The apoptosis of human gastric cancer cell line SGC-7901 Dead effect. [Results] The results showed that: After DHA complex treatment, obvious apoptotic nuclear morphologies were observed in human gastric cancer cell SGC-7901 cells. [Conclusion] The DHA complex can obviously induce the apoptosis of human gastric cancer cell line SGC-7901.
