[Sialic acid, steroids and proteohormones in maternal, cord and retroplacental blood].

Background: To study the storage of sialic acid in newborns reference concentrations for sialic acid were measured in maternal, retroplacental and cord blood and compared with the concentration of human placental lactogen (hPL) and estriol (E3). High serum concentrations of hPL and E3 in retroplacental blood indicate the synthesis of these products in the fetoplacental unit. The comparison of the serum concentrations give first informations for a possible role of the placenta as a place of production and storage of the investigated products.

[Diagnosis and therapy of toxoplasmosis infections in pregnancy at the Rostock University Gynecologic Clinic 1986-1994].

Over a period of eight years, 61 patients with toxoplasmosis infection in pregnancy were examined retrospectively at women's hospital. Diagnosis of maternal infection was based on seroconversion, positive IgM, raising IgG--titers above twofold, and very high primary titers in SFT. In 20 patients (32.

[Analysis of 122 twin deliveries with special reference to morbidity and mortality of the second twin].

122 consecutive twin deliveries between 1986-1992 were analysed retrospectively under special consideration of morbidity and mortality of the second twin. 13.9% of the twin deliveries occurred before the 33rd week of gestation.

[Tocolysis with ethanol--effects on the ethanol content of the blood in the mother and neonate].

In 10 pregnant women infusions with fructose and ethanol have been performed during labour until delivery. Ethanol concentration in blood have been estimated during delivery and in the post partum period. A decrease of labour activity could be found already with ethanol blood level below 0.

[East German percentile values for newborn infants--1985 relation of age, parity, body weight and height of the mother and the birth weight of newborn infants].

Based on an analysis of very comprehensive data material multidimensional investigations on connections between age, parity, weight and height of mothers and birth weight of infants have been made. Maternal height as well as maternal weight have a considerable influence on birth weight of infants. At the same maternal height infant birth weight will rise in connection with the rise of maternal weight.
