title: The ABO(H) paradoxical and aberrant secretion in human saliva.
abstract: The paradoxical secretion and aberrant secretion of the ABH substances have been studied in the saliva of 251 and 283 subjects, respectively. A standardized hemagglutination-inhibition method was used and the results were scored by an Inhibition Index. Frequencies of 4.3% for paradoxical secretion and of 5.3% for aberrant secretion were observed. Gel chromatography on Sephadex G-25 showed that only the paradoxical secretors have in their saliva the oligosaccharides which inhibit nonspecifically the anti-A, anti-B and anti-H reagents.
