Abstract
Serum ceruloplasmin, α1-antitrypsin, α2-macro-globulin and the iron and T3 binding proteins were studied in six women during abortion induced by hypertonic saline. After correction of the results for total serum protein changes (15%), no significant variations in the concentrations of the proteins studied could be observed within 48 hours following saline treatment. The insensibility of specific serum proteins as indicators of the welfare of the fetoplacental unit is discussed.
