title: [Increase in Alkaline Phosphatase Activity after High-Fat Meal Ingestion is Correlated to the Amount of ABH Substances in Saliva].
abstract: Intestinal alkaline phosphatase (IAP) appears in the circulation more frequently in blood group B or O secretors than in blood group A or AB secretors and non-secretors, and serum IAP activity rises following the ingestion of a high-fat meal. In a previous study, the occurrence of two IAP isoforms, with high (HIAP) and normal molecular mass (NIAP), in healthy sera was demonstrated by 6.0% polyacrylamide gel electrophoresis in the presence of 1% Triton X-100. NIAP was present in the fasting serum of only healthy blood group B or O secretors, but was present in all subjects following ingestion of a high-fat meal. We classified 56 healthy subjects into 3 blood groups: B (n = 19), O (n = 17), and A (n = 20), and measured their serum ALP activity in a fasting state and 6 h after a high-fat meal. The amount of ABH substances in the saliva of each subject was determined by the hemagglutination inhibition test. Correlation coefficients between the change in ALP activity after high-fat meal ingestion and the hemagglutination inhibition values in saliva were 0.925 in blood group B, 0.879 in blood group O, and 0.906 in blood group A. These results suggest that increases in ALP activity in the circulation following the ingestion of a high-fat meal are closely related to the amount of ABH substances in saliva.
