| pubmed-article:2355465 | pubmed:abstractText | So as to study the cell proliferation in a case with triple gastric cancers, we labeled an operated whole stomach with bromodeoxyuridine (BrdU) by the isolated organ perfusion system using artificial blood. Anti-BrdU immunohistochemical staining of sections from every part of the stomach was performed, and 3 separated cancerous lesions were all diagnosed as well differentiated adenocarcinomas. The labeling index (L.I.) of the cancerous lesions were found to differ from part to part. However, the L.I. tended to be higher in the superficial mucosal areas and in the cell-dense areas of the submucosa. In the almost normal fundic glands, the labeled zone was localized in the neck of the glands. The more metaplastic gastritis was advanced, the more the labeled zone shifted irregularly toward the bottom of the glands. Whenever the interstinal metaplasia was completed, the labeled zone was localized in the bottom of the glands. This method was found useful in studying the cell proliferation in the stomach without causing any harm to the human body. | lld:pubmed |
