Effect of smoking on maternal blood SP1 levels in late pregnancy. 1981

J N Lee, and J G Grudzinskas, and T Chard

Maternal blood levels of pregnancy-specific beta 1-glycoprotein (SP1) were measured in 1669 samples from 1078 patients at 31 to 40 weeks' gestation. Mothers who smoked throughout pregnancy showed a general reduction in infant birth weight and blood SP1 levels. Further analysis of these findings showed that SP1 levels were directly related to fetal weight, and suggested that smoking affects fetus and placenta as a single unit.

D011268	Pregnancy-Specific beta 1-Glycoproteins	Glycoproteins with the electrophoretic mobility of BETA-GLOBULINS, secreted by the placental TROPHOBLASTS into the maternal bloodstream during PREGNANCY. They can be detected 18 days after OVULATION and reach 200 mg/ml at the end of pregnancy. They are associated with fetal well-being.

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
