“…The average titer of the H substance in O persons is higher in milk. This finding confirms the results of Morganti et al [6] but not those of Denborough et al [3] who found higher H scores in saliva. An analysis of variance considering the PI average sali vary titers of individuals with different ABO blood groups indicated that the differences were statistically significant (F4>20-= 29.8; p < 0.001).…”

“…In a general way the titers we obtained in this last fluid are higher than those observed by other authors [3,5,6]; this can be ex plained by differences in the time that elapsed between delivery and sample collec tion. In our study this was standardized (2 days) while in these three other investiga tions the material was obtained at variable periods, after the third day.…”

“…Despite the fact that isolated quantitative studies in human saliva are relatively nu merous [9], comparative analysis between the ABH substances in saliva and milk are few in number [3,6], Investigations that in cluded the Lea antigen are even more re stricted [5]. Research done with the purpose of analyzing several genetic and nongenetic factors that might modify the ABH and Lewis antigen levels in these secretions is practically nonexistent; some authors in vestigated the saliva only from this point of view [13].…”

The saliva and milk of 250 parturient women were studied in relation to ABH antigen levels; part of the sample was also investigated for the Lewis (Le^a) substance. The levels of A and B are higher in saliva, and those of H and Le^a higher in milk. The H average salivary titers presented the relationship 0 > A₂ > A₁ > B > AB, but these differences were not present in milk. In addition, the salivary levels of A and B are similar in individuals of these groups but B > A in AB persons, and A₁ > A₂; while in milk A > B in A, B and AB subjects, and A₁≈ A₂. The amount of Le^a substance depends of the ABH secretor status in both secretions; but independently of this difference, the average titers were always higher in milk. Correlation coefficients between the levels observed in the two secretions are statistically significant for the A substance in A persons (0.46), H in B (0.58) and Le^a in all subjects tested (0.47). A stepwise multiple regression analysis performed to verify the influence of four genetic and six nongenetic variables in the ABH levels of both fluids indicated only one consistent modifying factor: ABO type.

“…Compared with saliva, human milk from group A and B secretors contains more H activity than A or B [5]. Szulman [8] has suggested that this may be caused by competition for galactose which is necessary to form A and B antigen.…”

In man the Sd^a antigen is present in most secretions with the greatest concentration in urine. There is little difference in the amount of Sd^a substance in the urine of newborn infants, pregnant women and normal adults but there is a much greater amount in the saliva of newborn infants than in adults. Approximately half the people whose red cells group as Sd(a-) secrete Sd^a substance in the urine. Anti-Sd^a antibody is present in 50% of Sd(a-) non-secretors of Sda substance, though most of these antibodies only react with the strongest Sd(a+) cells. The greatest Sda activity has been found in human meconium, guinea pig urine and guinea pig kidney. Activity can be detected in the urine of many animal species. The kidneys of 5 bird species did not contain Sd^a.
