| Abstract: | The distributions of acid alpha1-glycoprotein, alpha1-fetoprotein, beta-galactosidase and gastrin in gastric carcinoma and gastric ulcer as well as in the neighbourhood of these lesions were studied by means of immunohistochemical methods on imprint preparation. We could not find significant differences between gastric carcinoma and the nonneoplastic lesions, except for the acid alpha1-glycoprotein. The results of this first study indicate that the immunochemical and immunohistological assay of acid alpha1-glycoprotein might be of practical value in diagnosing malignant changes of gastric mucosa. |
