The mechanisms of such treatment have been proposed as inhibition of proliferation and angiogenesis, as well as induction of differentiation and apoptosis, as has been tested by various in vivo and in vitro experiments. in our experiments, it has also been demonstrated that after the treatment of arsenic trioxide, the k562 cells has undergone major morphological changes, which included nuclear shrinkage, membrane bleb and scattered apoptotic bodies. dna gel electrophoresis also discovered that the typical " dna ladder " phenomena in the treatment group, while the control group showed the regular genomic banding
我們在實驗中觀察到as _ 2o _ 3作用人紅白血病k562細胞后，細胞生長明顯變緩，部分細胞出現皺縮、染色質濃聚及胞膜起泡現象，部分細胞胞膜破裂，在其周圍有緻密的凋亡小體出現， dna電泳出現典型的凋亡「梯狀」帶，提示as _ 2o _ 3能有效抑制k562細胞生長，誘導k562細胞凋亡。 -
