[OPISTHORCHIASIS AS A PROMOTER OF GASTRIC CARCINOGENESIS].

The paper presents an experimental model of gastric cancer in the presence of chronic opisthorchiasis, which has been created to study its possible role in gastric carcinogenesis. The performed investigation has supported the hypothesis that opisthorchiasis plays a promoting role in the development of experimental gastric cancer. A larger number of experimental hamsters receiving the carcinogen methylnitronitrosoguanidine (MNNG) developed earlier gastric tumors in. the presence of chronic opisthorchiasis than the control animals in the experiment.
