In a study of 464 inner-city black infants, whose mothers were recruited prenatally based on alcohol and cocaine use during pregnancy, gestational age of less than 38 weeks was significantly correlated with cocaine use in the mothers (283). The infants were tested at 6.5,12, and 13 months of age the cocaine-exposed infants were more excitable, preferred faster frequencies of stimulation, had more difficulty habituating, were more reactive, and showed a greater startle response to noise. Moreover,... 

Gestational diabetes mellitus (GDM) is defined as glucose intolerance which is first recognized during pregnancy. Gestational diabetes complicates about 7% of all pregnancies. Clinical detection is important, as therapy will reduce perinatal morbidity and mortality.

Three studies examined the effects of endosulfan exposure on reproductive performance in rats. Consumption of estimated doses of endosulfan of up to 9 and 8 mg/kg/day by male and female rats, respectively, for 2 weeks prior to mating and continued consumption throughout gestation resulted in no adverse effect on mating performance, pregnancy rate, or gestation (Hoechst 1982). This study is limited in that the actual intake of test material was quantified only during the first 2 weeks of exposure, and a relatively small number of animals was used. Similarly, consumption of 5 mg/kg/day by male rats and... 

Uniformly labeled C-8-D with a specific activity of 2.99 juc/mg was administered orally to pregnant females at 2 /xg/kg/day from 6-15 days of gestation. Three females were sacrificed on alternate days during days 6-20 of pregnancy. Triplicate samples of fetus, placenta, blood, brain, abdominal fat, and sartorius muscle were procured from each female. The samples were dissolved in 1 ml of Soluene (Packard Instruments) to which 15 ml of Aquasol were added. Each sample vial was counted for 30 min in a Nuclear Chicago Mark I liquid scintillation counter. 

In rare instances (0.5% to 2% of pregnancies), NVP progresses to hyperemesis gravidarum.9 Treatment may require the use of enteral or parenteral nutrition if weight loss is present. A corticosteroid such as methylprednisolone may be considered. Methylprednisolone is associated with oral clefts in the fetus when used during the first trimester therefore, corticosteroids should be reserved as a last resort and should be avoided during the first 10 weeks of gestation.9,11...

Exchanges between bone and soft tissue stores of americium would be expected to be more rapid during periods of active bone metabolism such as infancy and childhood, pregnancy, and menopause. Thus, it is possible that, in humans, some of the maternal bone americium stores may be transferred to the fetus during gestation and may be incorporated into fetal bone during the development of the fetal skeleton. 

Three cows calved after the feeding of the hay was discontinued (Table I). The pregnancy of the cows was apparently normal and there were no abnormalities in any of the calves. This indicated that the level of DDT was not sufficiently high to affect the cows or calves during the period of gestation.
