“…Perera et al (1998) found that fetal development was adversely associated with PAH-DNA adduct levels, and that transplacental exposure to PAHs in ambient air could compromise fetal development. Air pollution may affect maternal respiratory function or general health, which may in turn impair uteroplacental and umbilical blood flow, transplacental glucose, and total insulin, all of which are important determinants of fetal growth (Vorherr, 1982). Ambient air pollution or its effective constituents could be inhaled and absorbed into the maternal bloodstream, and subsequently interfere with nutritional development of the fetus.…”

“…Multiple sociodemographic and clinical factors are also believed to influence fetal growth (Kramer, 2003). Intrauterine growth restriction (IUGR) is an important predictor of neonatal morbidity and mortality (Vorherr, 1982;Kramer, 1987). Severely growth restricted fetuses are at increased risk of stillbirth, and those born alive are at increased risk of neonatal death as well as short-term morbidity from hypoglycemia, hypocalcemia, and polycythemia (Kramer, 1987;Duvekot et al, 1995;Kramer, 2003).…”

Previous research demonstrated consistent associations between ambient air pollution and emergency room visits, hospitalizations, and mortality. Effect of air pollution on perinatal outcomes has recently drawn more attention. We examined the association between intrauterine growth restriction (IUGR) among singleton term live births and sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), carbon monoxide (CO), ozone (O 3 ), and fine particles (PM 2.5 ) present in ambient air in the Canadian cities of Calgary, Edmonton, and Montreal for the period 1985-2000. Multiple logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for IUGR, based on average daily levels of individual pollutants over each month and trimester of pregnancy after adjustment for maternal age, parity, infant gender, season, and city of residence. A 1 ppm increase in CO was associated with an increased risk of IUGR in the first (OR ¼ 1.18; 95% CI 1.14-1.23), second (OR ¼ 1.15; 95% CI 1.10-1.19) and third (OR ¼ 1.19; 95% CI 1.14-1.24) trimesters of pregnancy, respectively. A 20 ppb increase in NO 2 (OR ¼ 1.16; 95% CI 1.09-1.24; OR ¼ 1.14; 95% CI 1.06-1.21; and OR ¼ 1.16; 95% CI 1.09-1.24 in the first, second, and third trimesters) and a 10 mg/m 3 increase in PM 2.5 (OR ¼ 1.07; 95% CI 1.03-1.10; OR ¼ 1.06; 95% CI 1.03-1.10; and OR ¼ 1.06; 95% CI 1.03-1.10) were also associated with an increased risk of IUGR. Consistent results were found when ORs were calculated by month rather than trimester of pregnancy. Our findings add to the emerging body of evidence that exposure to relatively low levels of ambient air pollutants in urban areas during pregnancy is associated with adverse effects on fetal growth.

“…It has been suggested that fetal growth is influenced by genetic, nutritional, environmental, uteroplacental and fetal factors [11], In Japan, the fetal growth retardation and low birth weight infants make up about 10 percent of all deliveries, and their morbidity and mortality are very high in comparison with normal babies.…”

“…utrient uptake by the gravid uterus in domestic livestock is mainly dependent on the rate of uterine blood flow (UBF, l/min [1][2][3][4]). Reynolds et al [5] indicated that the increased rates of uptake or secretion of metabolites by tissues of the gravid uterus could be explained primarily by the increased rates of the uterine and umbilical blood flows.…”

Abstract. Blood flow to the gravid and nongravid uterine horns of four multiparous Holstein cows (mean ± SD, BW=641.8 ± 95.4 kg; age=4.8 ± 1.2 years; parity=3.0 ± 1.2) was measured on days 225, 248, and 266 of gestation. Surgery was conducted on day 214.5 ± 4.0 of gestation through the flank of the standing cows. Transit-time ultrasonic flow probes (diameter 12 or 14 mm) were fitted surgically around the uterine arteries of each cow. Surgery was completed within two hours of anesthesia, and the animals recovered rapidly following surgery. Uterine blood flow (UBF, l/min) was recorded at 10 sec intervals for approximately 23.5 hours; these values were averaged to determine UBF. The mean gravid UBF was significantly (P<0.05) greater than the nongravid UBF in this study. The range of the gravid and nongravid UBFs varied from 3.61 to 14.05 and 0.72 to 6.54 l/min, respectively. There were no changes (P>0.1) in the mean gravid and nongravid UBFs from day 225 to 266 of gestation.
