Objective To investigate the morphologic influence ofβ-carboline alkaloids on apoptosis,as well as the related inhibiting mechanism,in human gastric cancer cell cell SGC-7901.Methods Human gastric cancer Cell SGC-7901 was pretreated with 5different concentrations ofβ-carboline alkaloids(0,5,10,20,and 40μg/mL).Ultra structure of cell SCG-7901 was observed by transmission electronic microscope,and apoptosis of cell SCG-7901 was observed by fluorescence microscope.Results After 48 htreatment with different lev...
