Placental Handling Of Zinc In The Guinea Pig Abstract . Extraction of zinc from the perfusate was also slow, and partly by absorption. Maternofetal transfer of zinc was directly related to both uterine and umbilical blood flows. The high concentration of zinc in the syncytium, relative to both maternal and fetal plasma levels, suggests active uptake at the maternal surface, combined

Zinc deficiency has been identified as a malnutrition issue worldwide. ZN deficiency is more prevalent in areas of low animal consumption and high cereal consumption. It’s not that the diet is low in ZN but more so the bio-availability of ZN which plays a major role in its absorption. Phytic acid has been identified as the main inhibitor of ZN. Adolescents, children, infants, lactating

The influence of zinc on bone healing in rats Meta

The importance and necessity of the trace element zinc for tissue restitution after injuries has been known for a long time. The influence of zinc on the healing of tibial fractures in rats is studied by daily administration of 0.6 mg zinc-dl-aspartate compared to a non-treated control group. There is a significant decrease of bone-zinc concentration after fracture. This decrease
