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.
