In order to classify the human saliva, hemagglutination inhibition tests were performed, using a phytagglutinin, Agastsche rugosa and 268 human saliva specimens. The agastache rugosa extracts, which was absorbed by the human saliva, reacted upon the human red blood cells as inhibitor or non-inhibitor of hemagglutination.
The newly classified saliva types (inhibitor and non-inhibitor) were compared with the established saliva secretion types, blood groups, and serum types statistically. On the other hand, the agglutination inhibition tests were also carried out using the saliva stains in the same methods.
The results obtained could be summarized as follows:
1. Human saliva could be classified into two groups. One group inhibited the agglutination activities of agastache rugosa extracts to human red blod cells and the other did not.
The frequency of the former was 40% and the latter was 60% among the investigated 268 human saliva.
2. The new saliva types, inhibitor and non-inhibitor, showed no constant relation with the known saliva types, secretor and non-secretor.
3. The classification and distribution of the new saliva types showed no constant relation with that of the other known blood groups and serum types, such as ABO, MN, ARI-ch and ARN-CH, IPO and NPO, ICO and NCO respectively.
4. This new classification of human saliva type may be applicable for the classification of human saliva stains.
