Abstract
OBJECTIVE: We measured cord blood and urine 8-iso-prostaglandin F2α (8-iso-PGF2α) levels in babies of different gestational ages to determine lipid peroxidation status. METHODS: Babies at gestational ages of 28-43 weeks were divided into group A (28-32 weeks), group B (33-36 weeks), group C (37-41 weeks), and group D (42-43 weeks). 8-iso-PGF2α in umbilical cord blood (UCB) at birth and urine at 6 hours after birth was and tested by ELISA. RESULTS: UCB and urine 8-iso-PGF2α levels in group C were 130.09 ± 31.73 pg/ml and 27.14 ± 6.73 pg/ml, respectively. UCB 8-iso-PGF2α levels in group A and B were 188.42 ± 59.34 pg/ml and 189.37 ± 68.46 pg/ml, and urine 8-iso-PGF2α were 32.14 ± 7.32 pg/ml and 30.46 ± 8.83 pg/ml, respectively. Blood and urine 8-iso-PGF2α levels in group D (post-term) were 252.01 ± 46.42 pg/ml and 44.00 ± 8.50 pg/ml. For all babies, UCB and urine iso-PGF2α levels were significantly correlated (r = 0.65, P < 0.01). CONCLUSIONS: We established blood and urine iso-PGF2α levels in normal full-term babies. Urine 8-iso-PGF2α levels may reflect the extent of lipid peroxidation in babies. In pre-term and post-term babies, there was evidence for increased lipid peroxidation.
