Abstract:
Objective To explore the relationship between the serum level of leptin,growth hormone(GH),insulin like growth factor-1(IGF-1),insulin like growth factor binding protein-3(IGFBP-3)and those modulatine effects on fetal growth.Methods One hundred and thirty-five cases of newborns were divided into 4 groups according to the relationship between born weight and gestational age.Group A:premature infants small for gestational age(SGA),n=30.Group B:premature infants appropriate for gestational age(AGA),n=36.Group C:mature infants small for gestational age,n=32.Group D:mature infants appropriate for gestational age,n=37.All infants were measured se-rum leptin,GH,IGF-1 and IGFBP-3 level with radiommunosassay(RIA).Results There were significant difference in the levels of leptin,GH,IGF-1,IGFBP-3 as group C0.05).There were positive correlation between levels of leptin,IGF-1 and IGFBP-3 in group A,B and C,while,there was positive correlation between only level of IGF-1 in group D.Conclusions Leptin,IGF-1 and IGFBP-3 may play an important role in the fetal growth regulation of premature infants and IUGR infants.IGF-1 also regulate intrauterine growth of group D.Another side,in group D,Leptin,GH,IGF-1 and IGFBP-3 don't regulate fetal growth.
