title: Production of group I pepsinogen by gastric carcinoma.
abstract: Group I pepsinogen levels were determined in the homogenized supernatant of the lymph nodes with metastasis of the gastric carcinoma by radioimmunoassay. Mean levels of group I pepsinogen were 941 ng/g and some of the lymph nodes showed very high levels compared with those of non-metastatic lymph nodes, 269 ng/g. They were also significantly higher than those of the sera in the same subjects, that is, the production of group I pepsinogen by gastric carcinoma was clarified.
