They were given natural Se dietetic liquid (100 μg / d) for 6-8 weeks during late pregnancy, and 48 controls were given placebo. They received similar routine prenatal care. The results revealed that Se supplement on the pregnant women prevented and decreased the incidence of PIH and gestational edema, and elevated the mother's blood Se level by 0.1008± 0.091 ppm in the treated group while decreased by 0.0402±0.046 ppm in the control group (P<0.01). The umbilical blood Se level was 0.2756± 0.100 ppm in the treated group and 0.1544 ± 0.051 ppm in the control (P<0.01). The differences of the neonatal birth weight and the amount of postpartum hemorrhage between the two groups were not significant.展开更多

Because the direct and indirect relationship between low calcium intake and many diseases, such as rachitis, young age myopia and hypertension, calcium supplementation has been a hot topic among nutritionists, Randomized trials of calcium supplementation during pregnancy were conducted in 212 healthy primipara. They were divided into 4 groups and pave 120mg, 240mg, Ig or 2g of calcium daily from 20 to 28wks of gestation up to delivery respectively. As a result, the incidence of PIH was 8.9%, 7.5%, 8% and 4% respectively in these groups, The control group (106 pregnant women) who did not receive calcium gave an incidence of 18%. Supplementation of 2g of calcium daily showed significant resutls in lowering the incidence of PM (P<0.05) without any adverse effects. In 1992 calcium supplementation was widely used in antenatal clinic. 200 cases with intake of 2g calcium were compared with corresponding non-calcium supplementation cases, and the incidence of PIH was 7.5% and 16.5% (P< 0.005) respectively. Mediating parathyroid hormone and renin activity are thought to be the effect of calcium on decreasing the incidence of PIH,展开更多
