| Abstract: | Objective To provide experiment materials for the biological characters investigation during the stomach carcinogenesis by establishing the stomach cancer model.Methods The Wistar rat stomach carcinogenesis was induced by addingN Methyl N' Nitro N Nitrosoguanidine(MNNG) into the drinking water and diet according to the different period in our experiment,and samples were collected periodically.Results By histological observation,the neoplasma was found in mucous limited in the 24th week;the infiltration was found in the 40th week.Conclusion The stomach carcinogenesis can be sucessfully induced by MNNG. |
