Secretor status and ABH antigens expression in patients with oral lesions

2007

Objectives: The aim of this work was to investigate the secretor status of patients with oral pre-cancerous and cancerous lesions and ABH antigens expression in fixed tissue sections of these patients. Study design: To reveal A, B and H antigens in tissue sections of patients with precancerous and cancerous oral lesions (n= 54) we used a modified specific red cell adherence technique (SRCA-test). Normal endothelial cells expressed ABH antigens, the presence of indicator erythrocytes at the lumen of the blood vessels served as a built in positive control. The test results were graded from negative adherence to very strongly positive adherence. Negative adherence was defined as a complete abs…
