ABSTRACT
Aim To study the effects of EVn-50 on human gastric carcinoma SGC-7901 cells in vitro and invivo. Methods Human gastric carcinoma SGC-7901 cells were cultured in vitro. The inhibitory rate of cells was determined by cell counting and the cell growth curve was made. Plate clone formation assay was carried out to detect the phenotypes of colony formation. Trail of human gastric carcinoma xenografts in nude mouse model was used to draw the transplant tumor growth curve and test inhibition rate of EVn-50 on human gastric carcinoma. The histopathological changes were observed by lightmicroscopy and electronmicroscopy. Results In vitro,EVn-50 at 1,10,100 mg?L-1inhibited the growth and proliferation of SGC-7901 cells in a dose-dependent manner and a time-dependent manner; The colony-forming rate was reduced drastically compared with control group(P
