Objective To investigate the the changes of reactive oxygen species in gastric cancer cell and its value on proliferation and apoptosis.Methods With flow cytometry,reactive oxygen species,apoptosis and hyperproliferation were detected in 30 fresh specimens from gastric cancer cells and adjacent normal tissues.Results Reactive oxygen species,apoptosis and hyperproliferation in gastric cancer cells were all significantly higher those in adjacent normal tissues.Conclusion Reactive oxygen species plays an important role in the development of gastric cancer. |
