Med., 1986, 148 (2), 239-240 - 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 941ng/g and some of the lymph nodes showed very high levels compared with those of non-metastatic lymph nodes, 269ng/g. They were also significantly higher than those of the sera in the same sabjects, that is, the production of group I pepsinogen by gastric carcinoma was clarified.
