title: [Secretory IgA in amniotic fluid].
abstract: Immunoglobulin composition was studied in the amniotic fluid (AF) and in the urine of newborn babies. IgA was revealed with the aid of anti-secretory component of the serum in 50 of 57 AF samples; in the urine of babies in the course of the first 24 hours after birth it was revealed in 2 of the 21 cases only. This fact and also the detection of the secretory IgA in the AF at the early periods of pregnancy permit to suppose the synthesis of IgA or of its C-fragment in the amniotic membranes.
