| Research Abstract |
We analyzed the polyunsaturated fatty acid (PUFA) compositions in maternal and cord blood erythrocytes of 523 pregnant women living along the shore of the Miyagi prefecture and determined the transport of arachidonic acid (ARA) and docosahexaenoic acid (DHA) across the placenta to the fetus. The PUFA levels of infants reflected those of their mothers, indicating that PUFA transport across the placenta to the fetus determined the PUFA compositions in cord blood erythrocytes. In the third trimester, the ARA level in maternal erythrocytes decreased compared with that in the second trimester, but no change in maternal DHA was observed. This finding suggested that the DHA in maternal blood satisfied the increasing demand of the fetus in the third trimester.
