Abstract:
From observation of women who had anaphylactic accidents to hymenoptera venoms, with positive histamine release, we have noticed that these same patients lose their histamine release during pregnancy. Measurement of histamine release to pollens confirms the existence of a histaminase, which develops from the third month of the pregnancy and which is the origin of the loss of histamine release. This study makes eliminates a possible anti-degranulation ability of pregnancy sera.
