[Pregnancy-specific beta-glycoprotein in the serum of women with a complicated early pregnancy].

The author determined pregnancy specific beta 1-glycoprotein in 109 women with threatened early pregnancy as 32 of the women suffered from abortus imminens with several unsuccessful pregnancies in the past as well as 67 women with abortus incipiens with bleeding ex utero. The author established that 87% of women with abortus imminens and preserved pregnancies had values of beta 1-glycoprotein close to those of normal pregnancy for the respective gestational week. 93% of women with abortus incipiens preserved pregnancies till term, but the specific glycoprotein was with in normal ranges.

[Effect of the glucose concentration in the maternal blood on the level of specific beta 1-glycoprotein].

The authors carried out studies on 20 women with normal pregnancy between 38 and 40 weeks gestation. Hypoglycemia, induced by insulin, was provoked in 10 of them, but hyperglycemia--in the other 10 women. Maternal blood samples for glucose and SP1 were taken on 15,30 and 60 min as well as on 2, 6, 12, 24 and 48 h after the onset of the trial.

[The serum concentration of specific beta 1-glycoprotein in trophoblastic disease].

Twelve women with hydatidiform mole were studied between 12 and 20 weeks-gestation. The level of SP1 was determined by radioimmunologic method. The author found statistically significant increase of SP1 over 90th percentile of gestational age (p less than 0.
