title: [Gonadotropic activity of the immunoglobulins from placental, abortion and donor blood].
abstract: Gonadotropic activity of 106 series of immunoglobulin preparations obtained in the USSR and-the People's Republic of Bulgaria was studied. In difference from donor immunoglobulins, all the preparations of placental materials were contaminated with chorionic gonadotropin. Gonadotropin content in the immunoglobulins made of abortion serum was 2--7 times greater than in the preparations from the retoplacental serum and the placental extracts. The mean results of gonadotropin content in the immunoglobulins obtained by biological studies differed from those obtained from the investigations by immunological methods since the mentioned methods apparently characterized different properties of the hormonal molecule.
