title: [Comparative study of the content of blood group substances A and B in immunoglobulins prepared from placental and donor sera].
abstract: Blood group specific substances A and B were revealed in all the samples of immunoglobulin commercial preparations made in the USSR, Bulgaria, and India from the retroplacental, abortion sera, and from the placental extract. Their content varied in different batches of the preparations--from 8 to 64 microgram/ml of substance A, and from 6 to 256 microgram/ml of substance B. In the majority of immunoglobulin batches prepared from donor sera no group-specific blood substances A and B were revealed; only in 3 of 14 batches was there revealed substance A in the amount of 3 microgram/ml.
