Maternal serum alpha 1-antitrypsin concentrations in normotensive and hypertensive pregnancies.

Maternal serum alpha 1-antitrypsin concentrations in normotensive and hypertensive pregnancies.

Maternal serum alpha 1-antitrypsin concentrations were measured serially in pregnant women who were normotensive and those with mild, moderate, and severe hypertension of pregnancy from 27 weeks' gestation to term. alpha 1-antitrypsin concentrations increased with advancing gestation in all four groups. In addition, the hypertensive pregnancies showed higher than normal concentrations at each s...

Serum alpha 1 antitrypsin and pulmonary emphysema.

Using isoelectric focusing (IEF) and radial immunodiffusion (RID) techniques, serum samples from 100 normal healthy adults and 21 patients with pulmonary emphysema were analysed to identify various alpha 1 antitrypsin phenotypes and the serum concentrations. Ten percent of the patients had low serum values. The normal or most common genetic form, MM, is the predominant phenotype in both control...

Serum alpha 1 antitrypsin in liver diseases.

Genetic variants of serum alpha 1 antitrypsin.

Complete absence of data on alpha 1 antitrypsin in this country prompted us to determine serum levels using radial immunodiffusion (RID) and phenotypes by isoelectric focusing (IEF) in 100 healthy adults (52 males and 48 females). Mean serum alpha 1 antitrypsin concentration in healthy subjects was 2.47 +/- 0.08 g/l and the main phenotypes MM (70%), M1 M2 (28%) and FM 3 (2%) are infrequent in o...

Neonatal and maternal platelet cytosolic calcium in normotensive and hypertensive pregnancies.

A prospective study investigated platelet cytosolic calcium in non-pregnant volunteers (n = 30) and samples from the umbilical veins of babies from both normotensive (n = 18) and hypertensive (n = 15) primigravidae, and their mothers. There was no significant difference between the neonatal umbilical venous platelet cytosolic calcium concentration (p[Ca2+]i) in babies born to normotensive primi...
