目的：探讨紫苏油对人乳腺癌系M C F7细胞的生长抑制和凋亡诱导作用，为开发紫苏油进行抗肿瘤提供理论基础。方法用不同稀释度的紫苏油处理人乳腺癌细胞系MCF7，做肿瘤细胞生长抑制的噻唑蓝（MTT）实验，Hoechst 33258与碘化丙啶（PI）染色荧光显微镜观察凋亡细胞的核形态改变，流式细胞术检测细胞凋亡率和凋亡峰。结果紫苏油对人乳腺癌细胞系MCF7的增殖有抑制作用，并有时间和浓度依赖性，而同类的大豆油没有此作用。用Hoechst 33258和PI染色观察到典型的凋亡细胞的核形态学改变。流式细胞术检测到细胞凋亡率随时间和紫苏油浓度的增加而增加。结论紫苏油具有抑制人乳腺癌M C F7细胞增殖和诱导细胞凋亡的作用，提示其有可能作为一种抗肿瘤药物应用于临床。

Objective To investigate perilla oil on human breast cancer MCF7 cell growth inhibition and induction of apoptosis , and provide a theoretical basis for the development of perilla oil anti-tumor .Methods Breast cancer MCF7 cells were treated with different dilutions of perilla oil to do tumor cell growth inhibition MTT experiment ,to observe the changes in the nuclear morpholo-gy of apoptotic cells with Hoechst 33258 and PI staining and fluorescence microscopy ,and to detect rate of apoptosis and apoptotic peak with flow cytometry .Results Perilla oil inhibited the proliferation on human breast cancer cell line MCF7 with a time-and concentration-dependent manner .Typical apoptotic nuclear morphological changes could be observed with Hoechst 33258 and PI staining under a fluorescence microscope .Detected by flow cytometry ,apoptosis rate was increased with time and concentration . Conclusion Perilla oil can inhibit human breast cancer MCF7 cell proliferation and induce apoptosis ,suggesting that it may be used as an anticancer drug in clinical practice .
