The contents of inorganic arsenic in three kinds of algae are determined using this method. The result shows that algae have a low content of inorganic arsenic, complying with the results frequently reported in recent years, in which combination of some testing methods such as HPLC-ICP- MS and HPLC-HGAFS are used. Compared with these results, the results obtained from national standard methods are relatively high, due to the inapplicability of atomic fluorescence method.

并运用本法检测了海带、裙带菜、紫菜等三种海藻中的无机砷含量，发现海藻中的无机砷含量并不高，原国标方法检测的结果就相对较高，原因主要是原国标方法中的原子荧光法不适合于海藻类样品，检测结果与近来国内外报道较多的HPLC-ICP- MS、HPLC—HGAFS等联用技术检测海藻类物质中无机砷含量结果基本吻合，结果良好。

Results:Whith the time and doses of ART incubation extended, ART significantly inhibited the proliferation of SGC-7901 cells and the inhibited effect shows dose-and -time-dependent. Obvious changes of apoptotic morphology were observed by invert microscope, fluorescence microscope, scanning electron microscope and transmission electron microscope, they showed that cells had marked nuclear condensation or the fragmentation of chromation as well as apoptotic , mitochondrial edema and vesicle , with the time of incubation extended , the proliferation rate become slow and the volume became small and transformed. FCM assay indicated that most of the cells were arrested in Go/Gi and the apoptotic peak appeared. During the prolong of incubation time, the apoptosis rate was increased. At the same time, the number of S and G2/M phase cells were decreased. The result of TUNEL indicant that there are apoptosis and necrosis.

结果：随着药物浓度的增加和作用时间的延长，蒿甲醚对胃癌SGC-7901细胞的抑制作用呈时间和浓度依赖关系：在倒置显微镜、荧光显微镜、扫描电镜和透射电镜下可观察到典型的凋亡细胞的形态改变，表现为：核固缩或染色质边聚或凝聚成大块状，可见凋亡小体，线粒体肿胀增殖，严重的空泡化，随作用时间的延长，细胞增殖速度减慢，细胞体积缩小变形；流式细胞术显示胃癌SGC-7901细胞出现明显的凋亡峰，随着作用时间的延长，其凋亡率逐渐升高，细胞周期阻滞在G_0/G_1期，S及G_2/M期细胞数大量减少；流式细胞术TUNEL检测结果显示细胞凋亡和坏死同时存在。
