【Abstract】 The titer of me blood-group substances in human saliva samples of 500 normal adults (age 16~55 years) is presented. The level of blood-group substances in saliva samples is from zero to 2, but the number of saliva samples free from blood-group substances is very (0.6%) The secretion of A-group substance is unequal to that of B-group substance in the majority of AB- group saliva samples. The secretion of H-substance is lower than that of corresponding bloodgroup substances in the vast majority of A-, B-, and AB-group saliva samples. Paradoxical phenomena (false-neutralisation) may arise in the analyses of bloodgroup substances when undi-11uted saliva samples and lowrtiter sera are used for analysis, but if saliva samples have been diluted to 1:10 or more and other methods are taken, the false-neutralization phenomena can be avoided.更多还原
