| Summary: | 碩士 === 中山醫學院 === 營養科學研究所 === 84 === The purposes of our study are to investigate the differences
of vit A, vit Eand red blood cell phospholipid fatty acids in
newborns and their mothers as well as to find out whether there
are any relationships between maternal bloodand cord blood for
the nutrients measured. The subjects of our study are twenty-
nine pairs of mothers and their term infants from Chung Shan
Memorial Hospital. Maternal venous blood was collected both in
the first trimesterand at delivery, and cord blood was collected
at delivery.Plasma vitamin Aand E levels were determined by
high performance liquid chromatography andred blood cell
phospholipid fatty acid profile were estimated by gas chromat-
ography. Plasma vitamin A, E and vit E／total lipid of mothers
were significan-tly greater than those of their term neonates (p
＜0.05). Maternal plasma vit E and vit E／total lipid were
significantly greater in the first trimester thanat delivery (p
＜0.05). However, there was no difference of maternal plasmavit
A between first trimester and at delivery. Red blood cell
phospholipid o-leate and linoleate weresignificantly greater in
maternal blood than in cord b-lood (p＜0.05). However, stearate
and arachidonate were significantly greater in cord blood than
in maternal blood (p＜0.05). There was significantly greater
docosahexaenoate at delivery than in the first trimester (p
＜0.05). Maternal vit E was positively correlate between the
first trimester and at delivery (r=0.38, p＜0.04). Maternal
palmitate, linoleate, arachidonate and docdsahexaenoate were
also positively correlated to those of their neonates. Gender of
newb-orns did not affect the nutrients measured. In summary, the
results suggested that there were significantly relationships
between maternal blood and cord bl-ood for some nutrients. The
nutritional status of mothers may affect the nutri-tional
outcome of their neonates.
