Outline of Final Research Achievements

Feto-Placental 11 β HSD2 controls glucocorticoid disclosure to fetus. We investigated the influence by which these give it to fetus growth. Placental HSD11B2 mRNA was employed as a placental 11βHSD2 activity. Although urinal cortisone/cortisol metabolism ratio(u-F/E) didn't correlate with placental HSD11B2 mRNA, we thought that u-F/E could estimate fetal 11βHSD2 activity.
The placental HSD11B2 mRNA in SGA infants was significantly low compared with AGA infants. And, The placental HSD11B2 mRNA was correlated with SDS of the birth weight and birth head circumference respectively. u-F/E in SGA infants was significantly low compared with AGA infants. However, there was no correlation between urine F/E and fetal growth. These relations were admitted in girls.
